Viridian Vitamin D3 400iu

Viridian Vitamin D3 400iu is a gentle and appropriate daily maintenance dose of vitamin D3 (cholecalciferol) sourced from lichen — a certified vegan form of vitamin D3, as the majority of vitamin D3 supplements are derived from lanolin in sheep's wool. This product is particularly suitable for those with moderate vitamin D requirements, children, and individuals who prefer a lower-dose supplement for ongoing nutritional insurance.

Vitamin D3 is the form of vitamin D produced in the skin upon exposure to ultraviolet B radiation from sunlight, and is the preferred form for supplementation due to its superior bioavailability and greater efficacy in raising blood 25(OH)D levels compared to vitamin D2. In countries with limited sunlight exposure during the winter months, such as the United Kingdom, dietary sources and supplementation become critical to maintaining adequate vitamin D status.

Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus, maintenance of normal bones and teeth, normal muscle function, normal immune system function, maintenance of normal blood calcium levels, normal cell division, and the maintenance of normal teeth. Low vitamin D levels have been associated with increased risk of bone loss, immune impairment, muscle weakness, fatigue, and poor mood, among many other health concerns.

The lichen-derived vitamin D3 in this product is identical in structure and activity to the vitamin D3 produced in the skin and from lanolin, making it an effective vegan option without compromise on efficacy. This supplement contains 100% active ingredients, no artificial fillers, and is suitable for vegans. Produced in the UK to Viridian's strict ethical standards.
