A “vitamin A B C D E supplement” is a multivitamin that covers the five vitamin families people most often look for by letter — A, B, C, D and E — in a single daily tablet. It is a shopper’s shorthand rather than an industry term, which is why searching for it returns mostly generic multivitamins. This guide explains what the letters cover, what each one is authorised to do, and what to check on a label before you buy.
Why “vitamin A B C D E” is hard to shop for
Almost nobody in the supplements industry uses the phrase. Manufacturers name products “multivitamin”, “A–Z”, “one a day” or “complete”, and then list the contents in a panel on the back. Shoppers, reasonably enough, search for the letters they actually want.
The result is a mismatch. You search for five specific vitamins and get results for products containing twenty-odd ingredients, most of which you did not ask for, at doses the listing does not show you. The useful question is not “which multivitamin is best” but “does this product actually contain A, B, C, D and E at a meaningful amount, and what else has been added?”
Two things are worth knowing before you compare anything:
“B” is not one vitamin. It is a family of eight: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6, B7 (biotin), B9 (folate) and B12. A product described as containing “vitamin B” might contain one of them or all eight. This is the single biggest source of confusion in the category, and the place where listings are most often vague.
“D” is usually D3. Vitamin D comes as D2 (ergocalciferol) or D3 (cholecalciferol). D3 is the form the body makes in sunlight and is the form used in most supplements. If a label just says “vitamin D”, it is worth finding out which.
What each vitamin is authorised to do
In Great Britain, only claims on the official register may be made about a vitamin, and only when the product contains enough of it to qualify. That register is a genuinely useful shopping tool, because it tells you what is established rather than what is marketed. Here is what applies to the five letters:
| Vitamin | Authorised claims |
|---|---|
| A | Vitamin A contributes to the maintenance of normal vision · contributes to the normal function of the immune system · contributes to the maintenance of normal skin |
| B1 (thiamine) | Thiamine contributes to normal energy-yielding metabolism · contributes to the normal function of the heart · contributes to normal psychological function |
| B2 (riboflavin) | Riboflavin contributes to the reduction of tiredness and fatigue · contributes to the maintenance of normal red blood cells · contributes to the protection of cells from oxidative stress |
| B3 (niacin) | Niacin contributes to normal energy-yielding metabolism · contributes to the maintenance of normal skin and mucous membranes · contributes to the reduction of tiredness and fatigue |
| C | Vitamin C contributes to the normal function of the immune system · increases iron absorption · contributes to normal collagen formation for the normal function of skin |
| D | Vitamin D contributes to the maintenance of normal bones · contributes to the normal function of the immune system · contributes to the maintenance of normal muscle function |
| E | Vitamin E contributes to the protection of cells from oxidative stress |
Anything a product claims beyond this list is marketing, not established science. If a listing promises energy, focus, detox or immunity in stronger language than the wording above, that is a signal about the seller rather than the product.
Six things to check before you buy
1. Which B vitamins are actually in it. Look for the individual entries — thiamine, riboflavin, niacin — not a line that says “vitamin B complex”. A product naming three B vitamins is being more honest than one naming none.
2. The %NRV column, not the milligrams. Nutrient Reference Value is the percentage of a day’s reference intake per tablet. It is the only figure that lets you compare two products directly, because milligram amounts differ wildly between vitamins — 80 mg of vitamin C and 80 mg of vitamin D would be very different propositions.
3. Whether the doses are sensible rather than dramatic. More is not better with vitamins, and A and D in particular are fat-soluble, meaning the body stores rather than excretes the excess. Around 100% NRV is the sensible target for a daily multivitamin. Products advertising many times the reference intake are selling a number, not a benefit.
4. The full ingredient list, including what is not a vitamin. Tablets need binders, fillers, anti-caking agents and often a coating. These are legitimate and unavoidable, but they should be declared. A listing that shows only the active ingredients is showing you half the label.
5. Where it was made. In the UK, look for GMP certification — Good Manufacturing Practice, an audited standard covering how the product is produced and tested. It is not a quality claim about the formula, but it is a meaningful floor.
6. Allergens and suitability. Vitamin D3 is commonly derived from lanolin (sheep’s wool), which makes many D3 products unsuitable for vegans. Gelatine capsules are not vegetarian. If this matters to you, check rather than assume.
How to compare products
Once you have those six answers, comparison is straightforward: line up the %NRV figures for each of A, B1, B2, B3, C, D and E, then divide the price by the number of days the pack lasts. A 120-tablet pack at one a day is four months; a 60-tablet pack at two a day is one month. Pack size alone tells you very little.
The JeaKen option
JeaKen Multivitamin A B C D E is a 120-tablet pack — four months at one tablet a day — containing vitamins A, B1, B2, B3, C, D3 and E, each at 100% of the reference intake. It is manufactured in the UK under GMP-certified standards, is non-GMO and is free from artificial additives.
It is deliberately a narrow product. It covers the five letters people search for and does not add the botanical extracts, minerals and amino acids that pad out longer formulas. If you want a broader spectrum, an A–Z style multivitamin is the better fit; if you want the letters and nothing else, this is built for that.
For the per-nutrient breakdown and the full ingredient declaration, including binders and coating, see the label on the pack.

What is a vitamin A B C D E supplement?
It is a multivitamin covering the five vitamin families most often searched for by letter — A, B, C, D and E — usually in a single daily tablet. It is a shopper’s term rather than an industry one, so products matching the description are normally sold as multivitamins.
Does “vitamin B” mean all eight B vitamins?
Not necessarily. The B family has eight members: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5, B6, B7 (biotin), B9 (folate) and B12. A product listing “vitamin B” may contain one or all of them. Check for the individual names in the nutrition panel.
Is vitamin D the same as vitamin D3?
D3 (cholecalciferol) is one of two forms of vitamin D, the other being D2 (ergocalciferol). D3 is the form the body produces in sunlight and the form used in most supplements. Note that D3 is often derived from lanolin, so it may not be suitable for vegans.
Can I take vitamins A, B, C, D and E together?
They are routinely combined in a single multivitamin tablet, which is the standard format for this category. Follow the dosage on the label and do not exceed it. If you take other supplements, are pregnant or breastfeeding, or are on medication, speak to your doctor or pharmacist first.
How much of each vitamin should a daily multivitamin contain?
Around 100% of the Nutrient Reference Value (NRV) per daily dose is the usual target. Vitamins A and D are fat-soluble, meaning the body stores rather than excretes any excess, so doses well above the reference intake are not automatically better.
What does %NRV mean on the label?
NRV stands for Nutrient Reference Value — the percentage of a day’s reference intake supplied per tablet or serving. It is the figure to compare between products, because raw milligram amounts are not comparable across different vitamins.
When is the best time to take a multivitamin?
Vitamins A, D and E are fat-soluble and are generally taken with a meal containing some fat. Beyond that, the most effective timing is whichever one you will remember consistently.
Are these tablets suitable for vegetarians or vegans?
It depends on the product. Vitamin D3 is commonly sourced from lanolin, and tablet coatings and capsule shells vary. Check the suitability statement on the pack rather than assuming.
How long does a 120-tablet pack last?
At one tablet a day, 120 tablets is roughly four months. When comparing prices between products, divide the pack price by the number of days it covers rather than comparing pack prices directly.
Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Do not exceed the stated dose. Keep out of the reach of young children. If you are pregnant, breastfeeding, taking medication or under medical supervision, consult your doctor or pharmacist before use.
