Between October and early March, the NHS says we do not make enough vitamin D from sunlight. That is why many people in the UK consider a daily vitamin D supplement through autumn and winter.
This guide explains what that NHS advice means, which authorised health claims apply to vitamin D and vitamin B12, and how to buy Proaid’s Winter Immune options — as a bundle or separately.
Why vitamin D matters in the darker months
The NHS advises that everyone should consider taking a daily vitamin D supplement during autumn and winter. It also says you should not take more than 100 micrograms (4,000 IU) of vitamin D a day from supplements.
In Great Britain, vitamin D is authorised to contribute to:
- the normal function of the immune system
- the maintenance of normal bones
- the maintenance of normal muscle function
These claims describe the nutrient itself. They are not a claim that any one product “boosts” immunity, treats deficiency or replaces medical advice. Proaid does not use the NHS logo, and nothing here means the NHS endorses Proaid.
Where vitamin B12 fits
Vitamin B12 is often taken as a daily tablet alongside other staples. Authorised claims for vitamin B12 include that it contributes to:
- the normal function of the immune system
- the reduction of tiredness and fatigue
Again, these are nutrient claims only — not disease claims, and not promises of energy “boosts”.
Winter Immune Bundle: what’s in it
Our Winter Immune Bundle puts two 180-pack staples together for about six months of daily use:
- Vitamin D3 2000IU (50mcg) tablets, 180 pack
- Vitamin B12 1000mcg tablets, 180 pack
How to use: take one tablet of each a day. Both contribute to the normal function of the immune system.
Bundle or buy separately: you can checkout the bundle in one go, or buy the D3 and B12 packs on their own if you only need one nutrient.

Safety

- Keep out of sight and reach of children.
FAQ

It also says not to take more than 100 micrograms (4,000 IU) a day from supplements. That is general public-health advice, not an endorsement of Proaid.
