Vitamin D is a group of fat-soluble vitamins that play a crucial role in the regulation of calcium and phosphorus absorption, bone health, and immune system function. Vitamin D3, also known as cholecalciferol, is a type of vitamin D that is synthesised by the skin when exposed to sunlight. It is the most active and most commonly used form of vitamin D in supplements.

Vitamin supplementation may be important to fill nutritional gaps and prevent deficiencies that may lead to health problems. While a balanced diet is the best way to obtain vitamins, certain factors can make it difficult to get enough. Vitamin D supplements can provide a convenient and effective way to ensure adequate vitamin D intake and support overall health and well-being.

    Helps boost the immune system

    I have ordered the vitamin 3 D as I have read it helps to boost the immune system. So I have only just started taken them


    Good value, well packaged.

    Tablets look fit for purpose, and quick delivery. No reason to believe they will not provide all the vitamin D we require.

  9. V. Brazier

    Compact Packaging

    The thin, rectangular packaging is a good idea to save space but is less stable than circular and can tip over spilling contents.

    Would have given 4 but..

    Great shaped bottle for keeping in the cupboard and easily recognisable.. but just getting ONE tablet out is a problem. Tip the bottle slightly and too many come out! Redesign the neck maybe?
