Pure Encapsulations Vitamin D3 5,000 IU is a high-strength vitamin D food supplement, supplied as 60 vegetarian capsules. Each capsule provides 125 mcg (5,000 IU) of vitamin D3 (cholecalciferol), a dose considerably higher than a standard everyday vitamin D supplement, and is intended to be taken as directed by a healthcare professional.

Key Features

• High-strength single dose: each capsule provides 125 mcg (5,000 IU) of vitamin D3, well above the 10 mcg most adults need daily, so it suits higher intake needs identified by a healthcare professional rather than routine everyday use.
• Supports bones, muscles and immunity: vitamin D contributes to the maintenance of normal bones, normal muscle function and the normal function of the immune system.
• Minimal ingredient list: contains only two other ingredients, hypoallergenic plant fibre (microcrystalline cellulose) and a vegetarian capsule shell (hydroxypropyl methylcellulose), with none of the 14 major EU allergens.
• Vegetarian capsules: the capsule shell contains no animal-derived material, so it's suitable for vegetarians.
• Simple daily dose: one capsule taken with a meal, straightforward to fit into a daily routine when a higher dose has been recommended.

Is 5,000 IU of vitamin D too much to take every day?

NHS guidance says adults should not take more than 100 mcg (4,000 IU) of vitamin D a day, as more could be harmful. One capsule of this product provides 125 mcg (5,000 IU), which is above that general limit, so it is intended for use as directed by a healthcare professional rather than for everyday, unsupervised use. See the Warnings section for more detail.

Who is this high-strength vitamin D3 supplement suitable for?

It's intended for people who need a higher vitamin D intake than the standard recommendation, for example when a healthcare professional has advised it to help correct a low vitamin D level. Most adults only need 10 mcg of vitamin D a day, so this high-strength capsule is not intended for routine daily use without professional guidance.

Is this vitamin D3 supplement suitable for vegetarians and people with allergies?

Yes. The capsules are vegetarian, made from hydroxypropyl methylcellulose, and the only other ingredient is hypoallergenic plant fibre (microcrystalline cellulose). The product does not contain any of the 14 major allergens listed under EU food labelling law (Regulation 1169/2011), including gluten-containing cereals, milk, soya, egg, fish, crustaceans, molluscs, peanuts or celery.
