The Lamberts Vitamin D 4000iu provides 100μg of this crucial micronutrient in the preferred D3 form (cholecalciferol). This concentration is increasingly recommended to address vitamin D deficiencies. These easy-to-swallow capsules are manufactured within the UK, adhering to the pharmaceutical GMP standards of the British Pharmacopoeia.

In the United Kingdom, the primary dietary source of vitamin D is fatty fish. Despite sun exposure being a significant contributor to vitamin D production in the skin, several factors affect the population’s ability to generate sufficient vitamin D levels. These factors include the season, geographical latitude, time of day (optimal exposure between 11 am and 3 pm), cloud cover (complete cloud cover reduces vitamin D production by 50%), pollution, skin melanin content (darker skin types produce less vitamin D upon sun exposure), and sunscreen use (SPF 8 and above). Even during summer, when vitamin D synthesis is more achievable, approximately 45% of the English population is estimated to have plasma vitamin D levels below 40nmol/L (vitamin D insufficiency), and 75% fail to reach the desirable levels of 75nmol/L. The natural vitamin D3 in this product is chemically identical to the form synthesized naturally in the body after skin exposure to sunlight.

In summary, this product:

• Contains small, easy-to-swallow capsules
