Buy Vitamin D – Supplements with Vitamin D3 as Capsules & Drops

Vitamin D is a fat-soluble vitamin and chemically belongs to the group of secosteroids. The most important form for food supplements is vitamin D3 (cholecalciferol). In this category you'll find vitamin D supplements from Scheunengut – with a defined content in international units (IU), often as capsules or drops and lab-tested.

Origin & Extraction

Vitamin D3 is traditionally obtained from lanolin (wool fat). For vegan supplements, lichen extract serves as the raw material from which vitamin D3 can be obtained from plants. Both sources provide the same molecular form but differ in the starting material.

Standardisation & Format

The content is given in international units, with common levels ranging from 1,000 to 5,000 IU per serving. Vitamin D is available as a capsule, oil-based drops or a tablet. It is often combined with vitamin K2 (MK-7); as a fat-soluble vitamin, it pairs well with other fat-soluble vitamins such as vitamin A and vitamin E.

Häufige Fragen zu Vitamin D

What does vitamin D do?

Vitamin D has several approved functions. It contributes to the normal function of the immune system, to the maintenance of normal bones and teeth, and to normal muscle function. It also supports normal absorption and utilisation of calcium. This makes vitamin D3 one of the most important micronutrients – particularly during the darker, low-sunlight months.

What's the difference between vitamin D3 from lanolin and from lichen?

Vitamin D3 (cholecalciferol) is traditionally obtained from lanolin, i.e. wool grease. For vegan products, lichen extract is used instead as a plant-based raw material. Both sources provide the same molecular form and therefore the same effective vitamin D3 – they differ only in the starting material. Anyone wanting a vegan option should choose the lichen-derived variant.

Which dosage and format suits me?

Content is given in international units (IU), with common strengths ranging from 1,000 to 5,000 IU per serving. Vitamin D is available as a capsule, an oil-based drop, or a tablet. Since it's fat-soluble, oil-based formats work particularly well. Which strength suits you best depends on your personal needs.

Why is vitamin D3 combined with K2?

Vitamin D3 and K2 (MK-7) are often offered together, as both play a role in bone metabolism – a very popular and sensible combination. Our vitamin D products are made in Germany, lab-tested, and have a clearly defined IU content, so you can manage your intake with full transparency.
