Vitamin D 2000 DUO Gold

Vitamin D is one of the few nutrients the body can't reliably get from food alone — most of it is produced in the skin through sunlight exposure, which makes daily supplementation especially valuable during darker months or for indoor lifestyles.

Vitamin D 2000 DUO Gold delivers a high dose of 2000 IU (50 µg) vitamin D3 per capsule, paired with native linseed oil to support absorption.

Because vitamin D is fat-soluble, taking it alongside a source of healthy fat — like the omega-rich linseed oil built into this formula — helps the body use it more effectively.

Each capsule also contains lutein, a plant-derived carotenoid with antioxidant properties.

The formula uses NutriGellets® technology, encapsulating the active ingredients in a protective gelatin matrix without artificial colorants, preservatives, or coating agents.

It's produced in-house at BIOGENA Good Health World in Salzburg, Austria, under FSSC 22000 certification, with every batch independently tested by the German LEFO Institute.

 The product carries the Austrian Science Gold quality seal and follows Biogena's pure substance principle — free from titanium dioxide, GMOs, nanoparticles, and magnesium stearate.

Gluten-free and lactose-free. Note: this formula is not vegan, as NutriGellets® use fish-derived gelatin (Biogena offers a lichen-derived vegan D3 alternative for those who need one)
