Lamberts Vitamin D3 4000iu 100mg 30 tabs

Lamberts Vitamin D 4000iu provides 100µg of this important micronutrient in the preferred form of D3 (cholecalciferol). This strength is the increasingly recommended for the correction of vitamin D deficiencies. These easy-to-swallow capsules are manufactured in the UK to the British Pharmacopoeia's pharmaceutical GMP standards.

The sun's ability to contribute to the synthesis of vitamin D by the skin is affected by: the season (highest amounts of vitamin D are produced during the summer), latitude (the UK is quite north), time of day in which the skin is exposed to the sun (11am and 3pm exposure is necessary), cloudiness (a full cloudy sky causes a 50% decrease in vitamin D production by the skin), smog/environmental pollution (most residents live in large cities), the skin's melanin content (people with a dark skin phototype synthesize smaller amounts of vitamin D after exposure to sunlight) and the use of sunscreen (SPF 8 and above).

Even during summer when vitamin D synthesis becomes more feasible, it is estimated that 45% of the English population have plasma vitamin D levels below 40nmol/L (vitamin D insufficiency) and 75% fail to achieve the ' late' levels of 75nmol/L. The naturally derived vitamin D3 of this product is of the same chemical form as that which is synthesized naturally in the body following exposure of the skin to solar radiation.

The use of Lamberts Vitamin D 4000iu is recommended to be done on the recommendation of the health professional.
