Vitamin D is essential for strong bones, active muscles, and a well-functioning immune system — but most of us get it primarily from sunlight, making it hard to maintain adequate levels during darker months or with limited sun exposure.

Biogena's Vitamin D3 2000 Vegan delivers 2,000 IU (50 µg) of cholecalciferol per capsule, sourced entirely from lichen rather than the lanolin (sheep's wool) typically used in conventional vitamin D3 supplements.

This makes it one of the few truly plant-derived, bioavailable forms of vitamin D3 available — ideal for anyone following a vegan or vegetarian lifestyle.

The formula follows Biogena's "pure substance principle": only active ingredients, with no artificial colorants, preservatives, magnesium stearate, titanium dioxide, or technological additives such as anti-caking or binding agents.

Each capsule is free from gluten, lactose, and fructose, and every batch is independently tested by the German LEFO Institute for potency and purity.

Production takes place in-house at Biogena's FSSC 22000-certified facility in Salzburg, Austria.

Vitamin D3 supports calcium and phosphorus absorption in the intestine, contributing to the maintenance of normal, healthy bones and teeth. It also plays a role in normal muscle function and helps the immune system operate as it should — functions that become especially relevant when sunlight exposure drops in autumn and winter.
