Vitamin D is often referred to as ‘the sunshine vitamin’ as it is naturally produced under the skin following exposure to sunlight. During winter periods we can’t make vitamin D from sunlight because the sun is too low in the sky. Because it’s difficult to get enough vitamin D from food, Public Health England recommends supplementation of vitamin D to maintain bone and muscle health.

Dietary sources of vitamin D include fortified foods, eggs and fatty fish. Whereas most vitamin D3 supplements on the market are derived from the lanolin in sheep’s wool, Viridian Vitamin D3 capsules provide vitamin D3 in a vegan form derived from lichen. Viridian D3 has been clinically studied at the University of Surrey and proven to increase blood serum levels of vitamin D.

Vitamin D contributes to the maintenance of normal bones, teeth, muscle function and immune function. Vitamin D also contributes to normal absorption/utilisation of calcium and phosphorus.
