Product description Centrum Vitamin D Boost Multivitamin 30 Tablets
What Centrum Vitamin D Boost is
Centrum Vitamin D Boost is a daily multivitamin tablet with a higher-dose vitamin D component. Each tablet gives you 30 micrograms (1,200 IU) of vitamin D3 alongside a full multivitamin blend.
The 30-tablet pack gives you a month’s supply at one tablet per day. Take with water, ideally with a meal containing some fat for best vitamin D absorption.
Why the higher vitamin D dose matters
The UK Government recommends everyone considers taking 10 micrograms (400 IU) of vitamin D daily from October to March, when sunlight can’t produce enough vitamin D in the skin. Some people should take vitamin D all year round, including those with limited sun exposure, darker skin, or spending long hours indoors.
At 30 micrograms per tablet, Centrum Vitamin D Boost gives three times the basic recommendation. This higher dose suits people who want stronger vitamin D support alongside their other vitamins.
The dose stays well within safe limits. The UK safe upper limit for adults is 100 micrograms (4,000 IU) per day. At 30 micrograms, one tablet leaves room for vitamin D from food and (in summer) sunlight.
Complete 23-nutrient formula
The tablet delivers 13 essential vitamins plus 10 minerals in a single dose. This makes it a full daily multivitamin, not just a vitamin D top-up.
For people who currently take a plain vitamin D supplement AND a multivitamin, Centrum Vitamin D Boost lets you cut down to one tablet. This suits many people looking for a simpler routine.
Food supplement status
Centrum Vitamin D Boost sits in the food supplement category, not the licensed medicine one. This means it doesn’t carry MHRA approval and can’t make medical claims.
We can only use the approved EU/UK health claims for its nutrients. So we can’t say the product ‘treats’ vitamin D deficiency or ‘cures’ immune problems. We can say the nutrients support normal body functions.

A complete multivitamin with 6x more vitamin D than Centrum Advance for immunity, bones, and energy
Centrum Vitamin D Boost is a daily multivitamin food supplement from Haleon (the makers of Centrum). Each tablet delivers 30 micrograms (1,200 IU) of vitamin D3, plus 22 other essential nutrients including all 13 vitamins.
The vitamin D dose sits at the heart of this product. At 30 micrograms per tablet, it gives you six times more vitamin D than the standard Centrum Advance multivitamin. This makes it a good choice if you want extra vitamin D support without taking two separate products.
The dose also sits comfortably within safe daily intake for adults. The UK safe upper limit is 100 micrograms per day, so 30 micrograms leaves plenty of room for dietary vitamin D from foods like oily fish, eggs, and fortified cereals.
Vitamin D contributes to normal function of the immune system, normal absorption of calcium and phosphorus, and maintenance of normal bones, muscles, and teeth. These are the approved EU/UK health claims for vitamin D.
Beyond vitamin D, the tablet packs in vitamin C and zinc for immune support, magnesium for bones and muscle function, calcium for bones, and vitamin B12 to help release energy from food. The full 23-nutrient formula covers your daily vitamin and mineral needs.
Take one tablet daily with water, preferably with food. Vitamin D is fat-soluble, so a meal with some fat helps absorption.
Centrum Vitamin D Boost suits adults who want a single daily tablet covering both a complete multivitamin and higher-dose vitamin D. This works well for many people in the UK, especially through autumn and winter when sunlight is limited.
The formula suits vegetarians and is free from wheat, lactose, nuts, and gluten. However, always check the current pack label for the latest ingredient details.
Centrum Vitamin D Boost is a food supplement, not a licensed medicine. Don’t use it in place of a varied diet and healthy lifestyle. It works best as part of a balanced approach to nutrition, sunlight (safely), and activity.
At Courier Pharmacy, we stock Centrum Vitamin D Boost as part of our vitamin range. Our pharmacy team can help you work out if it suits your needs, or whether a plain vitamin D supplement or a lower-dose multivitamin would fit better.
When to see a doctor about vitamin D or vitamins
Centrum Vitamin D Boost is a food supplement for daily wellbeing. However, some situations call for a doctor rather than self-supplementation.
You suspect vitamin D deficiency: symptoms include bone pain, muscle weakness, low mood, and frequent infections. A blood test tells you if levels are actually low
You’ve been diagnosed with vitamin D deficiency: this may need prescription-strength vitamin D (20,000 IU or 40,000 IU capsules) for several weeks, not a food supplement
You have sarcoidosis, tuberculosis, hyperparathyroidism, or lymphoma: these conditions affect vitamin D handling
You have chronic kidney disease or liver disease: vitamin D handling may be affected
You take digoxin, thiazide diuretics, or certain seizure medicines: interactions are possible
You have high blood calcium levels (hypercalcaemia) or a history of calcium kidney stones
You already take another vitamin D supplement, cod liver oil, or a different multivitamin. Combining products can lead to excessive intake
You’re pregnant or breastfeeding: routine antenatal vitamins usually include vitamin D at appropriate doses. Extra vitamin D may not be needed
You have persistent tiredness that doesn’t improve after 4-6 weeks. Fatigue has many causes and needs proper assessment
Signs of vitamin D overdose (rare): nausea, vomiting, weakness, frequent urination, kidney stones, confusion. Stop the supplement and see your doctor
Centrum Vitamin D Boost is a daily multivitamin food supplement with 30 micrograms (1,200 IU) vitamin D3 per tablet, six times more vitamin D than Centrum Advance.
Complete 23-nutrient formula with all 13 essential vitamins plus 10 minerals, including vitamin C, zinc, magnesium, calcium, and vitamin B12.
One tablet daily with water, preferably with food. The 30-tablet pack lasts one month at the standard dose.
Suitable for vegetarians. Wheat-free, lactose-free, nut-free, and gluten-free. Check the current pack label for the full ingredient list.
Food supplement, not a licensed medicine. See your GP for suspected vitamin D deficiency, and avoid combining with other vitamin D or multivitamin supplements. Available from Courier Pharmacy.
What is Centrum Vitamin D Boost: overview
A daily adult multivitamin food supplement with 30 micrograms (1,200 IU) vitamin D3 per tablet, the highest-dose vitamin D in the Centrum range.
Complete 23-nutrient formula with all 13 vitamins plus 10 minerals covering daily nutritional needs.
Combines the convenience of a multivitamin with higher vitamin D support, reducing the need for two separate products.
Suitable for adults, vegetarians, and people avoiding wheat, gluten, lactose, and nuts.
Food supplement, not a licensed medicine. Not for use in confirmed vitamin D deficiency, see your GP for prescription-strength vitamin D if needed.
Where Centrum Vitamin D Boost fits in vitamin D supplementation
Vitamin D supplements come in many formats: plain vitamin D tablets, sprays, drops, capsules, and combined multivitamins.
Standard doses range from 10 micrograms (basic RDA) through 25-50 micrograms (higher-dose supplements) up to 100 micrograms (upper safe limit). Prescription vitamin D goes even higher (500-1,000 micrograms weekly) for correcting deficiency.
Centrum Vitamin D Boost at 30 micrograms sits in the higher end of routine daily supplements, enough to boost levels for most people without approaching safety limits.
Centrum Vitamin D Boost vs Centrum Advance
Centrum Advance is the standard Centrum multivitamin. It contains vitamin D at 5 micrograms per tablet, half the basic UK RDA.
Centrum Vitamin D Boost has 30 micrograms vitamin D per tablet, six times the amount in Centrum Advance. Choose Vitamin D Boost if you want extra vitamin D support alongside your multivitamin, especially through autumn and winter.
Centrum Vitamin D Boost vs plain vitamin D supplements
Plain vitamin D supplements come in doses from 10 to 100 micrograms per tablet. They give vitamin D only, without other vitamins or minerals.
Choose Centrum Vitamin D Boost if you want a full multivitamin as well. Choose plain vitamin D if you already get a good range of nutrients from your diet and just want targeted vitamin D support.
Centrum Vitamin D Boost vs cod liver oil
Cod liver oil contains vitamin D and vitamin A, plus omega-3 fatty acids. Standard cod liver oil gives around 5-10 micrograms vitamin D per dose.
Cod liver oil suits people who want the omega-3 benefits too. Centrum Vitamin D Boost gives more vitamin D and a full multivitamin blend, but no omega-3s.
Centrum Vitamin D Boost vs Centrum Women or Centrum Men
Centrum Women and Centrum Men are gender-tailored multivitamins. They contain different iron levels (Women: with iron; Men: without or lower) and other adjustments.
Centrum Vitamin D Boost is a general adult formula, not gender-specific. If you’re a woman with heavy periods (needing iron support) or want gender-specific balancing, the Women or Men formulas may fit better.
Centrum Vitamin D Boost vs Centrum Silver 50+
Centrum Silver 50+ is designed for adults over 50, with adjusted nutrient levels for the age group (higher B12, higher vitamin D than Centrum Advance, less iron).
Centrum Vitamin D Boost has higher vitamin D than either Advance or Silver 50+. Older adults who want strong vitamin D support could choose Vitamin D Boost, but Centrum Silver 50+ is designed specifically for the 50+ age group.
Centrum Vitamin D Boost vs prescription vitamin D
Prescription vitamin D (20,000 IU or 40,000 IU capsules) is used for correcting confirmed vitamin D deficiency. Doses are much higher and usually given weekly for 6-12 weeks.
Centrum Vitamin D Boost is for daily maintenance and general support, not for correcting deficiency. If your blood tests show significant deficiency, see your GP for prescription vitamin D.
Where to spend your money
If budget matters, plain vitamin D 25-50 microgram tablets often cost less than multivitamins with high-dose vitamin D. However, Centrum Vitamin D Boost delivers both the vitamin D and a full daily multivitamin, which can work out cost-effective if you’d otherwise buy both.

Main active nutrient in Centrum Vitamin D Boost
Vitamin D3 (cholecalciferol) 30 micrograms (1,200 IU) per tablet
Vitamin D3 (cholecalciferol) is the same form of vitamin D your skin makes when exposed to sunlight. It's the natural, active form of vitamin D found in animal sources and produced by the body.
Vitamin D3 is more effective at raising blood vitamin D levels than vitamin D2 (ergocalciferol, the plant-derived form). Most supplements now use D3 for this reason.
The body converts vitamin D3 into its active hormone form in two steps, first in the liver, then in the kidneys. The active form regulates calcium absorption, bone health, immune function, and many other body processes.
Approved health claims for vitamin D
Vitamin D contributes to normal function of the immune system. Vitamin D contributes to normal absorption and utilisation of calcium and phosphorus. Vitamin D contributes to normal blood calcium levels. Vitamin D contributes to the maintenance of normal bones, muscles, and teeth. Vitamin D has a role in the process of cell division.
Other nutrients in Centrum Vitamin D Boost
Complete vitamin range (all 13 essential vitamins)
Vitamin A, thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), vitamin B6, biotin (B7), folic acid (B9), vitamin B12, vitamin C, vitamin D (the boosted nutrient), vitamin E, and vitamin K. These cover the full range of essential vitamins needed for normal body functions.
Mineral range (10 essential minerals)
Calcium, phosphorus, magnesium, iron, zinc, copper, manganese, selenium, chromium, and molybdenum. These minerals support bone health, immune function, energy metabolism, and many other body processes.
Vitamin C and zinc for immune support
Vitamin C and zinc both contribute to normal function of the immune system, alongside vitamin D. This gives Centrum Vitamin D Boost a strong immune-supportive profile.
Magnesium and calcium for bones and muscles
Magnesium supports normal muscle function and normal energy-yielding metabolism. Calcium is needed for normal bones and teeth. Together with vitamin D, these support bone and muscle health.
Vitamin B12 for energy
Vitamin B12 contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue. It also supports red blood cell formation and nervous system function.
What Centrum Vitamin D Boost doesn't contain
Free from wheat, lactose, nuts, and gluten. Suitable for vegetarians. Check the current pack label for the full ingredient list, as formulations can be updated over time.
What is Centrum Vitamin D Boost for?
Supporting immune function
Vitamin D, vitamin C, and zinc all contribute to normal function of the immune system. This combined support suits people wanting to support their immune health, especially through winter.
Supporting bones and teeth
Vitamin D helps your body absorb calcium and phosphorus from food. Calcium and vitamin D together contribute to normal bones and teeth. Magnesium supports bone health too.
Supporting muscle function
Vitamin D and magnesium both contribute to normal muscle function. Low vitamin D is a common cause of muscle weakness and aches, particularly in older adults.
Reducing tiredness and fatigue
Vitamin B12, vitamin C, and other B vitamins contribute to the reduction of tiredness and fatigue. If your tiredness stems from suboptimal nutrient intake, a good multivitamin may help.
If tiredness comes from other causes (sleep, thyroid, mental health, other medical conditions), a multivitamin won't help and you need medical assessment.
Filling nutritional gaps
Even with a healthy diet, many people fall short on some vitamins and minerals. A daily multivitamin fills common gaps without requiring perfect eating habits.
Centrum Vitamin D Boost suits people who want the reassurance of covering all vitamin and mineral bases in one tablet.
Autumn and winter vitamin D support
The UK Government recommends adults consider taking vitamin D from October to March, when sunlight can't produce enough in the skin. Centrum Vitamin D Boost's 30 micrograms suits this need well.
Year-round vitamin D for at-risk groups
Some people should take vitamin D year-round: those with limited sun exposure, darker skin, spending long hours indoors, older adults, or people who cover most of their skin. Centrum Vitamin D Boost fits this ongoing need.
What Centrum Vitamin D Boost isn't for
Not for treating confirmed vitamin D deficiency. This needs prescription-strength vitamin D from your GP.
Not for children, choose age-appropriate products instead.
Not as a substitute for a healthy diet and lifestyle. Real food, sun exposure (safely), and activity remain the foundations of good health.
Not to combine with other vitamin D supplements or multivitamins. This can push intake above safe levels.
How does Centrum Vitamin D Boost work?
Vitamin D activation and use
Vitamin D3 from the tablet absorbs in the small intestine, alongside dietary fat. Once absorbed, it travels to the liver, where it converts to 25-hydroxyvitamin D (the storage form and the form measured in blood tests).
The kidneys then convert 25-hydroxyvitamin D into 1,25-dihydroxyvitamin D (calcitriol), the active hormone form. Calcitriol acts on cells throughout the body, bone, gut, immune cells, muscle, and many others.
Vitamin D helps regulate calcium absorption from the gut, supports normal calcium and phosphorus levels in blood, and contributes to healthy bones, muscles, and immune function.
How other vitamins and minerals work
Each vitamin and mineral in the formula has its own role. Vitamin C is an antioxidant and immune supporter. B vitamins work in energy metabolism. Iron supports oxygen transport. Zinc supports immune function and wound healing. Magnesium supports muscle and nerve function. And so on.
The synergy of the full nutrient blend is why multivitamins remain popular. Nutrients work together, not in isolation.
Time to reach steady blood levels
Vitamin D blood levels rise gradually. Steady state (where daily intake balances daily use and elimination) takes 8-12 weeks of consistent use.
This is why blood tests to check vitamin D levels should be done after at least 3 months of supplementation to reflect the true impact of your current dose.
Treatment dosage for Centrum Vitamin D Boost
At a glance
Age: adults
Dose: one tablet daily
Timing: any time of day, with water, preferably with food
Duration: continuous daily use as part of a healthy routine, especially through autumn and winter
Do not exceed the recommended daily dose
Do not use as a substitute for a varied diet and healthy lifestyle
Adult dose
Take one tablet daily with water, preferably with a meal. A meal with some fat (from any source) helps vitamin D absorption because vitamin D dissolves in fat, not water.
Any meal of the day works. Choose a time that fits your routine so you're less likely to forget.
Not for children
Centrum Vitamin D Boost is for adults. For children, choose age-appropriate multivitamins or plain vitamin D supplements sized for children.
The NHS recommends a daily vitamin D supplement of 8.5 to 10 micrograms for babies and children under 4. Older children and teenagers can take up to 10 micrograms daily.
Pregnancy and breastfeeding
Discuss any multivitamin with your midwife first if you're pregnant or breastfeeding. Antenatal vitamin products (like Pregnacare or Boots antenatal vitamins) are specifically designed for pregnancy needs, with folic acid and appropriate iron levels.
The NHS advises 10 micrograms of vitamin D daily during pregnancy and breastfeeding. Centrum Vitamin D Boost gives 30 micrograms, so check with your midwife before using it during pregnancy.
Older adults
Older adults often benefit from higher vitamin D intake. Skin produces less vitamin D from sunlight as we age, and many older people spend more time indoors.
The NHS recommends people over 65 take a daily vitamin D supplement all year round. Centrum Vitamin D Boost suits this need, though a plain vitamin D supplement (without the extra multivitamin) may also work well.
People with limited sun exposure
If you rarely get out in the sun (housebound, care home residents, those who cover most of their skin for cultural or religious reasons, night-shift workers), the body can't make enough vitamin D from sunlight.
Year-round vitamin D supplementation is recommended for these groups. Centrum Vitamin D Boost fits this need well.
Duration
Vitamin D supplementation can continue year-round, especially for those at higher risk of deficiency. For people who get plenty of sun in summer, October to March is the main period when supplementation matters.
There's no need to take breaks from vitamin D supplementation at these doses. However, long-term users should have vitamin D blood levels checked periodically.
How to take Centrum Vitamin D Boost
Standard use
Take one tablet daily with water, preferably with food.
Swallow whole
Swallow the tablet whole with a glass of water. Don't chew or crush it. If you have trouble swallowing tablets, tell us, we can suggest other vitamin D options in liquid, spray, or chewable format.
Take with food
Vitamin D is fat-soluble. Taking the tablet with a meal that contains some fat helps your body absorb more vitamin D. Any typical meal usually contains enough fat.
If you take it without food, you'll still absorb some vitamin D, just less than if taken with food.
Timing
Any time of day works. Many people find breakfast or dinner the easiest time to remember. Consistency matters more than the exact time.
Missed doses
If you miss a day, take the tablet as soon as you remember. If you don't remember until the next day, just carry on with your normal dose. Don't take two tablets in one day to catch up.
Take just one at a time
The one-tablet daily dose is designed to give you the right amount of each nutrient. Taking more than one tablet a day can push some nutrients above safe levels.
Don't combine with other multivitamins or vitamin D supplements
Avoid taking Centrum Vitamin D Boost alongside another multivitamin, cod liver oil, or plain vitamin D supplement. Combining products can push your total intake above safe levels for some nutrients.
Storage
Store the pack in a cool dry place, out of direct sunlight. Keep the container sealed. Keep well out of reach of children.
How quickly you'll notice a difference
Vitamin D blood levels rise gradually over weeks. Most people don't notice a direct 'feeling different' when taking daily vitamin D. The benefits (immune, bone, muscle support) come from maintaining healthy levels over time.
People starting from very low vitamin D levels may notice improved energy, mood, or muscle strength after 6-12 weeks. However, if you have significant deficiency, prescription-strength vitamin D from your GP will correct levels faster.
Warnings and precautions for Centrum Vitamin D Boost
Don't combine with other vitamin D or multivitamin products
Above all, don't take Centrum Vitamin D Boost alongside another multivitamin, cod liver oil, or plain vitamin D supplement. Combined intake can push some nutrients above safe levels, particularly vitamin D, vitamin A, and iron.
Check the labels of all your supplements. Many products contain overlapping ingredients.
Not for children
Centrum Vitamin D Boost is for adults. Children need age-appropriate multivitamin products with lower doses of most nutrients.
Keep out of reach of children. Adult multivitamins containing iron can be dangerous if a child accidentally takes them.
Pregnancy and breastfeeding
Discuss with your midwife before using Centrum Vitamin D Boost during pregnancy or breastfeeding. Antenatal-specific vitamin products are usually a better fit for pregnancy nutritional needs.
The NHS recommends 10 micrograms of vitamin D daily during pregnancy, less than the 30 micrograms in Centrum Vitamin D Boost.
Vitamin D toxicity risk (rare at this dose)
Vitamin D toxicity is rare at doses under 100 micrograms daily but can happen. Symptoms include nausea, vomiting, weakness, frequent urination, and (in severe cases) kidney stones, kidney damage, and heart rhythm problems.
Don't exceed one tablet daily. Don't combine with other vitamin D products.
Certain medical conditions
Discuss with your GP before taking Centrum Vitamin D Boost if you have any of these conditions:
Discuss with your GP or pharmacist before starting if you take:
Digoxin (heart medicine), vitamin D affects calcium levels, which affect digoxin safety
Thiazide diuretics (like bendroflumethiazide), can raise calcium levels when combined with vitamin D
Certain seizure medicines (phenytoin, carbamazepine, phenobarbital), reduce vitamin D activity
Corticosteroids (long-term), reduce vitamin D activity
Weight loss medicines that block fat absorption (orlistat), reduce vitamin D absorption
Iron content and its effects
The formula contains iron. If you take other iron supplements, you may exceed safe iron intake. Iron interacts with several medicines (levothyroxine, quinolone antibiotics, tetracyclines, bisphosphonates).
Iron also causes black or dark stools, which is normal but can be alarming if you don't expect it.
Calcium content and its effects
The formula contains calcium. If you also take calcium supplements or antacids containing calcium (Rennie, Tums), your total calcium intake may become too high.
Vitamin K content
The formula contains vitamin K. If you take warfarin, discuss with your GP before starting any vitamin K-containing product. Vitamin K affects how warfarin works.
Signs of allergic reaction
Rare allergic reactions to ingredients are possible. Symptoms include rash, itching, facial swelling, or breathing difficulty. Call 999 if severe.
Alarm symptoms need medical review
Don't self-supplement if you have any of these unexplained symptoms:
Persistent bone pain or muscle weakness
Frequent infections
Persistent tiredness that doesn't improve with supplementation
Symptoms suggesting vitamin D deficiency
Long-term use monitoring
Consider a vitamin D blood test every 6-12 months if you take Centrum Vitamin D Boost long-term. This helps ensure your levels stay in the healthy range without becoming too high.
Driving and machinery
No expected effects on driving or using machinery.
Alcohol
No direct interaction with alcohol. Heavy alcohol use, however, can affect vitamin and mineral absorption and metabolism.
Side effects of Centrum Vitamin D Boost
Common side effects
Centrum Vitamin D Boost is generally well tolerated. Mild stomach upset, nausea, or constipation can happen, especially if taken on an empty stomach. Taking with food usually resolves this.
Dark stools
The iron content can cause dark or black stools. This is normal and doesn't indicate bleeding. Very dark, sticky, foul-smelling stools may indicate upper gut bleeding, see your doctor if unsure.
Allergic reactions (rare)
Rare allergic reactions to ingredients are possible. Symptoms include rash, itching, facial swelling, or breathing difficulty.
Signs of vitamin D overdose (very rare at this dose)
Vitamin D overdose is very rare at 30 micrograms daily but symptoms would include nausea, vomiting, weakness, frequent urination, confusion, and (in severe cases) kidney stones or heart rhythm problems. Stop the supplement and see your doctor if these develop.
Serious side effects requiring urgent help
Above all, seek urgent medical help for signs of severe allergic reaction (facial or throat swelling, breathing difficulty, widespread rash). Call 999.
Drug interactions with Centrum Vitamin D Boost
Digoxin
Vitamin D affects calcium levels. High calcium can worsen digoxin toxicity. Discuss with your GP if you take digoxin.
Thiazide diuretics
Bendroflumethiazide and other thiazide diuretics reduce urinary calcium excretion. Combining with vitamin D can raise blood calcium too high.
Corticosteroids
Long-term steroid use reduces vitamin D activity. You may need higher vitamin D intake to maintain levels.
Anticonvulsants
Phenytoin, carbamazepine, phenobarbital, and some other seizure medicines increase vitamin D breakdown. People on these often need extra vitamin D.
Orlistat
Orlistat blocks fat absorption, which also blocks vitamin D absorption. Take vitamin D at least 2 hours away from orlistat doses.
Iron interactions (from the iron content)
The iron in the multivitamin formula reduces the absorption of levothyroxine, quinolone antibiotics, tetracyclines, and bisphosphonates. Leave at least 2 hours between Centrum Vitamin D Boost and these medicines.
Warfarin (from the vitamin K content)
Vitamin K in the multivitamin formula can affect warfarin. Discuss with your GP or anticoagulation clinic before starting.
Other vitamin or mineral supplements
Don't combine with other multivitamins, plain vitamin D supplements, cod liver oil, or high-dose single-nutrient supplements without checking the combined amounts.
Alcohol
No direct interaction. Heavy alcohol use can affect vitamin metabolism.
Frequently asked questions about Centrum Vitamin D Boost
What makes Centrum Vitamin D Boost different from other Centrum products?
The main difference is the vitamin D dose. Centrum Vitamin D Boost has 30 micrograms (1,200 IU) of vitamin D3 per tablet, six times more than Centrum Advance.
Is Centrum Vitamin D Boost a licensed medicine?
No. It's a food supplement, not a licensed medicine. It doesn't carry MHRA approval and can't make medical claims.
How much vitamin D does it contain?
30 micrograms (1,200 IU) of vitamin D3 per tablet. This is three times the basic NHS recommendation of 10 micrograms daily.
Is 30 micrograms of vitamin D too much?
No, it's well within safe limits. The UK safe upper limit for adults is 100 micrograms (4,000 IU) daily. At 30 micrograms, one tablet leaves room for vitamin D from food and sunlight.
How much should I take?
One tablet daily with water, preferably with food. Don't take more than one tablet a day.
Should I take it with food?
Yes, preferably. Vitamin D is fat-soluble, so a meal with some fat helps absorption. Any typical meal usually contains enough fat.
How long does a 30-tablet pack last?
30 days at one tablet per day. This is a one-month supply.
Is Centrum Vitamin D Boost suitable for vegetarians?
Yes. It's suitable for vegetarians.
Is Centrum Vitamin D Boost suitable for vegans?
Check the current pack label. Vitamin D3 is usually animal-derived (from lanolin, in wool grease). Vegans may need to choose a plant-based vitamin D2 or D3 supplement.
Is Centrum Vitamin D Boost gluten-free?
Yes. It's wheat-free, lactose-free, nut-free, and gluten-free.
Can I take it in pregnancy?
Discuss with your midwife first. Antenatal-specific vitamin products are usually a better fit for pregnancy. The NHS recommends 10 micrograms of vitamin D daily during pregnancy, less than in this product.
Can I take it while breastfeeding?
Discuss with your midwife or GP first. Postnatal-specific vitamins may fit better.
Can children take it?
No, this is for adults. Children need age-appropriate multivitamins with lower doses.
Can I take it with my other multivitamin?
No. Don't combine with other multivitamins, cod liver oil, or vitamin D supplements. Combined intake can push some nutrients above safe levels.
Can I take it with a plain vitamin D supplement?
No. Centrum Vitamin D Boost already contains 30 micrograms vitamin D. Adding another vitamin D supplement risks excessive intake.
Should I take it if I'm on warfarin?
Discuss with your GP or anticoagulation clinic first. The vitamin K in the formula can affect how warfarin works.
Should I take it if I'm on thyroid medication?
Yes, but timing matters. The iron in the multivitamin reduces levothyroxine absorption. Take levothyroxine first thing in the morning and Centrum Vitamin D Boost at least 4 hours later.
How quickly will I notice a difference?
Vitamin D blood levels rise gradually over weeks. Most people don't notice a direct feeling difference. The benefits come from maintaining healthy levels over time. Those starting from very low levels may notice improved energy or muscle strength after 6-12 weeks.
Can I take it forever?
Yes, at recommended doses. Long-term use is safe for most people. Consider a vitamin D blood test every 6-12 months to check your levels stay in the healthy range.
Can I use it to treat vitamin D deficiency?
No. Confirmed vitamin D deficiency needs prescription-strength vitamin D (usually 20,000 IU or 40,000 IU capsules weekly for 6-12 weeks). Centrum Vitamin D Boost is for daily maintenance, not for correcting deficiency.
How is it different from a plain vitamin D tablet?
Plain vitamin D tablets give only vitamin D. Centrum Vitamin D Boost gives higher-dose vitamin D plus 22 other essential nutrients. Choose based on whether you want a full multivitamin or just vitamin D.
Do I need a prescription for Centrum Vitamin D Boost?
No. It's a food supplement, available without prescription.
