The nine nutrients, and only nine
In Great Britain a supplement can only use health claims from the official register. The claim "contributes to the normal function of the immune system" is authorised for vitamin C, vitamin D, vitamin B6, vitamin B12, folate, iron, zinc, copper and selenium. That is the whole list. Echinacea, elderberry, chlorella, moringa, mushrooms, probiotics and "immune blends" have no such claim, however they are sold. Every product on this page contains at least one of the nine at a level above the claim threshold, and the claim is the only thing we say.
What the claim means, nutrient by nutrient
| Nutrient | Authorised claim | What it means | Threshold per day |
|---|---|---|---|
| Vitamin C | Vitamin C contributes to the normal function of the immune system | Immune cells need vitamin C to develop and work as they normally do. Vitamin C cannot be stored, so daily intake matters. | 12mg |
| Vitamin D | Vitamin D contributes to the normal function of the immune system | Immune cells carry vitamin D receptors; adequate status keeps their normal function normal. The NHS suggests UK adults consider vitamin D from October to March. | 0.75µg (30 IU) |
| Zinc | Zinc contributes to the normal function of the immune system | Zinc is a cofactor in the enzymes immune cells use to divide and signal. Cannot be stored; daily intake matters. | 1.5mg |
| Iron | Iron contributes to the normal function of the immune system | Iron is needed for immune cells to multiply and for the enzymes they use. | 2.1mg |
| Vitamin B12 and folate | Vitamin B12 / folate contributes to the normal function of the immune system | Both are needed for cell division, which the immune system does constantly. | 0.375µg B12 · 30µg folate |
| Copper, B6, selenium | Same wording for each | Copper is in Triple Zinc + Copper and Testosterone Pro; B6 and selenium are not currently in our range as standalone products. | 0.15mg Cu · 0.21mg B6 · 8.25µg Se |
Every claim above is about maintaining normal function. Boosting, strengthening, preventing colds or flu, and shortening illness are not authorised for any nutrient.

Zinc: keep total supplemental zinc under 25mg a day; take after food. Iron: not unless you need it; keep away from children, for whom iron overdose is dangerous; leave two hours between iron and thyroid medicine or antibiotics. Liposomal vitamin C products contain soya. Not for under 18s, or during pregnancy or breastfeeding without advice. If you are frequently unwell, that is a GP conversation, not a supplement one.

| Vitamin D for the winter | D3 5000 IU & K2 tablets | The everyday strength, within long-term guidance |
| Vitamin C on its own | Liposomal Vitamin C capsules or powder | Amount declared as vitamin C, not just the liposomal weight |
| Zinc on its own | Triple Zinc + Copper | Three forms, copper included to balance long-term use |
| Zinc for men | Spermer-Dons or T-Force | Zinc's fertility and testosterone claims alongside the immune claim |

Which vitamins and minerals are good for the immune system?
Nine nutrients carry the authorised claim that they contribute to the normal function of the immune system: vitamins C, D, B6, B12 and folate, and iron, zinc, copper and selenium. No other ingredient can make that claim in Great Britain, whatever the label suggests.
What does "contributes to the normal function of the immune system" mean?
That the nutrient is needed for the immune system to work as it normally does. It does not mean boosting immunity, preventing colds or shortening illness. No food supplement can claim any of those.
Do echinacea, elderberry, chlorella or moringa support immunity?
None has an authorised claim in Great Britain, so no seller can lawfully say so. That is why they are not in this collection. Our echinacea and chlorella are sold on the herbal and botanical page, on specification only.
How much do I need for the claim to apply?
At least 15% of the reference value per daily serving: 12mg vitamin C, 0.75µg (30 IU) vitamin D, 1.5mg zinc, 2.1mg iron, 0.375µg B12, 30µg folate. Every product here is well above its threshold.
Is vitamin D 10,000 IU safe every day?
UK guidance puts the long-term upper level at 4,000 IU a day. 10,000 IU is for short-term use or on GP advice, not for daily use over months. Our 5000 IU D3 K2 tablets are the everyday strength.
How much zinc is too much?
UK guidance is to keep supplemental zinc under 25mg a day, because long-term intake above that reduces copper absorption. Our zinc products declare the elemental amount so you can add them up.
Should I take vitamin C with iron?
Vitamin C increases iron absorption, which is itself an authorised claim. The Iron 4 Complex and the Multivitamin both pair them.
Do you supply these wholesale?
Yes, across the vitamins and minerals range: tablets and capsules in trade counts, liposomal vitamin C powder in bulk, white label available. Use the contact page for a trade price.
