250 µg Cholecalciferol · No Vitamin K · No Sugar · Adults Only
Vitamin D3 10,000 IU Tablets
Our strongest vitamin D, and the only one we make without vitamin K. One 8mm tablet holds 250 micrograms of cholecalciferol — 10,000 IU, 5,000% NRV — and nothing else working alongside it.
Deliberately high strength. One tablet provides more vitamin D than the 100 microgram daily figure given as the adult maximum — we say so on the pack and we say so here, because you should know it before you buy.
Directions & High-Strength Notice — Please Read First
Take one (1) tablet daily with a meal. A meal containing some fat is best, as vitamin D is fat-soluble. Do not exceed the recommended dose.
Be aware before you buy: one tablet provides 250 micrograms (10,000 IU) of vitamin D3 — 5,000% of the NRV. The NHS, EFSA and the UK supplement industry each give 100 micrograms a day as the maximum for adults. This product is above that figure, which is what "high strength" means here — it is not an accident and it is not hidden. The 5,000% figure looks more alarming than it is, and we explain exactly why further down.
That makes this a product to use deliberately rather than casually. If you would rather sit inside the 100 microgram figure, take it less often — the table below shows exactly what each frequency works out at, because the limit is a daily average. If you are at all unsure, speak to your GP or pharmacist, and consider a blood test first.
Most high-strength vitamin D is sold on the size of the number and nothing else. We would rather tell you how to use it, because 10,000 IU is a perfectly sensible amount of vitamin D to own and a poor amount to take every day.

Quick Answer
What it is. High-strength vitamin D3 tablets. 250 micrograms (10,000 IU) of cholecalciferol per 8mm tablet, 5,000% NRV. No vitamin K, no added sugar.
Directions. One tablet daily with a meal. Do not exceed the recommended dose.
Be aware. One tablet provides more than the 100 microgram daily figure the NHS, EFSA and the UK supplement industry each give as the adult maximum. That is what high strength means here. If you would rather sit inside it, take it less often — the table below shows what each frequency works out at.
Health claims. Seven authorised GB claims for vitamin D, quoted in full on this page in their legal wording. No heart or cardiovascular claim exists for vitamin D and none is made.
Not suitable for. Children, under-18s, pregnancy or breastfeeding without medical advice. Not vegan — the cholecalciferol is lanolin-derived. Do not take alongside another vitamin D supplement or a multivitamin containing vitamin D.
Price and packs. From £7.99. 120 to 1,000 tablets, plus a 25,000 trade pack. Made in the UK, dispatched from Essex, documentation free on request.
If you want to sit inside the 100 microgram figure
The 100 microgram adult maximum is a daily average, not a per-tablet limit. So although the directions are one tablet daily, you can place yourself wherever you want on this scale simply by taking it less often. Very few sellers will tell you this, and it is the single most useful thing to understand about any high-strength vitamin D.
| How often | Daily average | Inside the 100 µg figure? | 365 tub lasts |
| Once a week | 36 µg | Yes — 36% | 7 years |
| Twice a week | 71 µg | Yes — 71% | 3 years 6 months |
| Three times a week | 107 µg | No — above it | 2 years 4 months |
| Every day — as directed on the pack | 250 µg | No — above the figure | 1 year |
Read the bottom row honestly: taken every day as the pack directs, this product sits above the 100 microgram figure. That is the trade a high-strength tablet asks you to make, and we would rather set it out in a table than leave you to work it out. Twice a week brings you to 71 micrograms a day and once a week to 36 — both inside it, and both legitimate ways to use the product.
Whichever you choose, never take more than one tablet in a day and never alongside another vitamin D source. If you would rather have a tablet whose daily dose sits closer to the figure, our 5000 IU with K2 is the gentler of the two.
Why You Can Space Vitamin D At All
Vitamin D is fat-soluble. The body keeps a reserve of it in fat and liver tissue and draws on that between doses — which is exactly how anyone gets through a British winter on a summer's worth of sunlight.
That is the opposite of vitamin C and the B vitamins, which are water-soluble, are not stored, and genuinely need topping up daily. Official intake guidance for vitamin D is written as a daily average for this reason, and intermittent dosing is a normal, well-understood way to take it.
About that 5,000% on the label
It is the figure that makes people put the tub down, so here is what it actually means.
The NRV — Nutrient Reference Value — for vitamin D is 5 micrograms. Every supplement in the country has to calculate its percentage against that figure, because it is fixed in labelling law. 250 µg divided by 5 µg is 50, so the label has to print 5,000%. It is arithmetic, not a warning.
And note something odd: the NRV is 5 µg while the UK's own Reference Nutrient Intake is 10 µg — the figure the NHS advice is built on. The value used for labelling is half what the UK actually recommends you get. Two numbers, two different purposes, and nothing on a pack explains it.
So the percentage overstates the size of the dose by a factor of two before you start. Work in micrograms against the 100 µg ceiling instead — that is the comparison that tells you something, and it is the one in the table above.
Why we make a vitamin D with no vitamin K in it
Almost every high-strength vitamin D on the market now comes paired with K2. Ours is deliberately not, and there are three good reasons to want it that way.
You have been told to watch your vitamin K intake. This is the important one. Vitamin K is directly involved in blood clotting, which is the mechanism anticoagulant medicines such as warfarin act on — so people taking them are generally advised to keep vitamin K intake steady rather than add to it. If you need vitamin D but vitamin K is a complication, a D3-only tablet is the sensible shape. Speak to your doctor or pharmacist before starting any supplement in that situation.
You already take K2 separately. Plenty of people do, often at a strength of their own choosing. No reason to pay for it twice or end up stacking two sources.
You want the simplest possible tablet. One active, declared in full, nothing else along for the ride.
The seven authorised health claims for vitamin D
Around 220 health claims are authorised in Great Britain across every ingredient there is. Vitamin D holds seven of them, which is unusually strong ground. The wording is fixed in law and we are not permitted to improve on it — so here it is exactly as authorised, with a plain explanation of each underneath.
Each panel below gives the authorised wording exactly as it is fixed in law, then explains in plain English what that process actually is. The wording is the claim; the explanation narrows it rather than widening it.
| 🔄 |
Authorised Claim 1 of 7 Vitamin D contributes to normal absorption/utilisation of calcium and phosphorus This is the foundation the other six sit on. Vitamin D is involved in how the gut takes calcium and phosphorus out of food and moves them into the bloodstream. Calcium in your diet is only useful once it has been absorbed, and vitamin D is part of that step — which is why the two are so often discussed together. |
| 🩸 |
Authorised Claim 2 of 7 Vitamin D contributes to normal blood calcium levels Blood calcium is held within a narrow range by the body rather than allowed to drift with what you eat. Vitamin D contributes to maintaining that steadiness, drawing on what is absorbed from food and on the body’s own stores. |
| 🦴 |
Authorised Claim 3 of 7 Vitamin D contributes to the maintenance of normal bones Bone is living tissue, built largely from calcium phosphate and continually broken down and rebuilt rather than finished once and left alone. Vitamin D contributes to maintaining it — keeping a working structure working, not improving on it. |
| 💪 |
Authorised Claim 4 of 7 Vitamin D contributes to the maintenance of normal muscle function Muscle contraction is a calcium-signalled process, and vitamin D contributes to maintaining normal muscle function. This is the authorised claim people are least aware exists, and it applies as fully as the bone one. Note it is about maintaining function, not about strength or performance. |
| 🦷 |
Authorised Claim 5 of 7 Vitamin D contributes to the maintenance of normal teeth Teeth are mineralised with the same calcium phosphate chemistry as bone, so the same absorption role carries through. Vitamin D contributes to maintaining them. |
| 🛡 |
Authorised Claim 6 of 7 Vitamin D contributes to the normal function of the immune system Vitamin D contributes to the immune system working normally. In Britain the months when skin makes no vitamin D at all are also the months people spend indoors together, which is why this is the claim most winter buyers have in mind. It is not a claim about colds, infections or illness of any kind. |
| 🧬 |
Authorised Claim 7 of 7 Vitamin D has a role in the process of cell division Cell division is the basic process of tissue renewal and repair, going on constantly throughout the body. Vitamin D has an authorised role in it. Nothing more specific than that is authorised, and nothing more specific is implied. |
Those seven are the complete list and we make no claim beyond them. In particular there is no authorised heart or cardiovascular claim for vitamin D, and you will not find one implied anywhere on this page. The explanations above describe how the nutrient is involved; they are not additional promises.
Why British adults run low on this one
Between roughly October and March there is not enough UVB in sunlight at this latitude for skin to make any vitamin D at all, however long you stand outside. That is geography, not lifestyle, and it applies to everyone in the country.
The National Diet and Nutrition Survey — the government's rolling programme measuring what the UK eats and what shows up in people's blood — found that 16% of adults aged 19 to 64 have low vitamin D status, rising to 19% of 11 to 18 year olds. Intake from food alone runs at between a quarter and a third of the 10 microgram reference intake, because the richest everyday sources are oily fish and egg yolk and British diets do not contain much of either. Even counting supplements, adults 19 to 64 reach only 54% of the reference intake — and the reason is that just 17% of them take anything at all.
The NHS advises that everyone over four "should consider taking a daily supplement containing 10 micrograms of vitamin D" through autumn and winter, and year-round for people who are not often outdoors, people in care homes, people who cover most of their skin outside, and people with dark skin.
▸ We go through all of this properly in our guide to high-strength vitamin D dosing — including the full spacing tables for both our tablets.

Ingredients
Declared in full, in descending order as required:
Bulking Agents (Microcrystalline Cellulose, Dicalcium Phosphate), Vitamin D3 (Cholecalciferol), Anti-Caking Agents (Magnesium Stearate, Silicon Dioxide).
Four excipients and the active. We are not going to call this a no-filler product, because it is not one — 250 micrograms of anything is a speck, and a tablet needs bulk and flow agents to exist at all. What we will say is that there is nothing in it beyond what the job requires, and no added sugar of any kind.
Allergens
Our supplier's specification declares this product free from all fourteen allergens named in UK law:
No peanuts · No nuts · No sesame seeds · No milk · No egg · No cereals containing gluten · No soya · No lupin · No mustard · No celery · No fish · No molluscs · No crustaceans · No sulphur dioxide
Vegetarian yes, vegan no — and why
Vitamin D3 is cholecalciferol, and commercially it is made in one of two ways. The overwhelming majority — including the D3 in this tablet — comes from lanolin, the grease in sheep's wool, which is UV-treated to convert it. The sheep are sheared, not harmed, which is why the product is suitable for vegetarians. It is not vegan.
The only vegan route is lichen, which genuinely produces cholecalciferol and costs several times more. It is the same molecule and absorbs no differently — the difference is the source, not the quality. We do not currently use it, so we do not make a vegan claim, and we would rather tell you that plainly than let a plant-looking label imply otherwise.
If vegan sourcing matters to you, buy a product that states a named lichen source and can evidence it.
Safety — Please Read
Adults only. This is not a children's product and must not be given to children. The NHS daily maximum is 25 µg for infants under 12 months, 50 µg for ages 1 to 10, and 100 µg for ages 11 to 17 — one of these tablets is 250 µg. Children's vitamin D is sold as drops and low-dose chewables, and that is what they should have. Keep out of reach of children.
Do not stack it. This is the commonest way people go well over the ceiling, and it is nearly always an accident — a high-strength D3 plus a multivitamin plus a cod liver oil capsule, each sensible alone. Add up every vitamin D source you take. Do not take this alongside another vitamin D supplement or a multivitamin containing vitamin D.
Why the ceiling exists. Vitamin D is stored rather than cleared, so very high intakes accumulate over months. The NHS states that taking too much over a long period "can cause too much calcium to build up in the body (hypercalcaemia)", which "can weaken the bones and damage the kidneys and the heart." This is a long-term, high-intake effect and it is precisely why the 100 microgram figure exists. At one tablet daily this product is above that figure, so if you intend to take it long term, talk it through with your GP or pharmacist and ask about a blood test — or use the table above to place yourself lower.
Speak to your doctor or pharmacist before use if you take any prescribed medicine, or if you have a condition affecting blood calcium, the parathyroid glands or kidney function. Not recommended during pregnancy or breastfeeding without medical advice — the NHS applies the same 100 µg ceiling then, and recommends a 10 µg daily supplement, which is a much smaller product. You cannot get too much vitamin D from sunlight; the risk here is from supplements only.

Questions
Is 10,000 IU too much?
It is above the 100 microgram daily figure the NHS, EFSA and the UK supplement industry give as the adult maximum — one tablet is 250 micrograms. We state that openly rather than hiding behind the IU number. It is a deliberately high-strength product for people who want one, it is legal to sell and buy, and if you would rather sit inside the 100 microgram figure you can simply take it less often. The table above shows what each frequency works out at. If you are unsure which is right for you, that is a conversation for your GP or pharmacist, ideally with a blood test behind it.
Is it legal to sell a 10,000 IU tablet in the UK?
Yes. UK food supplement law governs which forms of vitamins may be used and how products must be labelled, but it sets no maximum dose for vitamin D. The 100 microgram figure comes from NHS advice, the EFSA tolerable upper intake level and a voluntary industry maximum agreed by CRN UK, the HFMA and PAGB — all advisory rather than statutory.
Can I take it less often than daily?
Yes, and many people do. Because the 100 microgram limit is a daily average, taking a 250 microgram tablet twice a week averages 71 micrograms a day and once a week averages 36 — both inside it. Vitamin D is fat-soluble and stored rather than cleared, which is why it does not need topping up every single day the way vitamin C does. Pick a frequency, peg it to fixed days and stick to it. A missed tablet is nothing to correct for — take the next one as normal and do not double up.
Why sell a tablet above the recommended maximum at all?
Because there is real demand for it from people working from a blood test result or a clinician's instruction, and because the alternative — stocking it while saying nothing about the 100 microgram figure, as most sellers do — serves nobody. Our answer is to sell it and put the number on the page.
Should I get a blood test?
It is the single most useful thing you can do before using any high-strength vitamin D. A serum 25-hydroxyvitamin D result turns the whole question from judgement into arithmetic. Your GP can arrange one and private tests are widely available. If a clinician gives you a dose, follow theirs rather than this page.
Can I take it with my other supplements?
Generally yes, with one firm exception: not alongside anything else containing vitamin D, including multivitamins and cod liver oil. Check the labels. If you take an anticoagulant or any prescribed medicine, speak to your pharmacist first.
Why no vitamin K in this one?
Deliberately. Some people have been advised to keep their vitamin K intake steady, usually because of an anticoagulant, and others already take K2 separately. For both, a D3-only tablet is the right shape. If you want the two together, our 5000 IU tablet includes K2 MK-7.
Is it vegan?
No — the cholecalciferol is lanolin-derived. It is suitable for vegetarians. We explain the whole thing above rather than leaving you to guess.
Which pack size should I buy?
Work from how often you intend to take it rather than the headline count. Taken daily, 120 tablets is four months and 365 is a year. Taken twice a week, 120 is around fourteen months and 365 is three and a half years. Larger packs cost less per tablet, so buy the size you would realistically get through rather than the biggest one on the list.

How this page is written
Every figure here is taken from our manufacturer's product specification sheet for this item, not from marketing material. The seven health claims are quoted in the exact wording fixed by law and checked against the Great Britain Nutrition and Health Claims Register before publication; the explanations alongside them narrow the claim rather than widening it, and no claim is made beyond the seven. The 100 microgram daily figure is stated plainly on the page rather than left out, because this product exceeds it. Written and maintained by Charge Products, trading since 2016. Last reviewed October 2026.
Only the seven authorised claims quoted above are made for this product. The plain-language explanations alongside them describe how the nutrient is involved and are not additional claims. No heart or cardiovascular claim is made or implied. Information on this page is general and is not medical advice — if you are unsure how much vitamin D to take, speak to your GP or pharmacist.
Food supplement. Not a medicine. Not a substitute for a varied and balanced diet or a healthy lifestyle. Do not exceed one tablet daily. Do not take alongside other vitamin D supplements or multivitamins containing vitamin D. Adults 18 and over only — not suitable for children. Keep out of reach of children. Not recommended during pregnancy or breastfeeding without medical advice. Speak to your doctor before use if you take any prescribed medicine, including anticoagulants, or if you have a condition affecting blood calcium, the parathyroid glands or kidney function. Store sealed in a cool, dry place away from light.
