Frequently asked questions

Good to know

What should I look for when buying food supplements?

It pays to read the label: how much is in one daily serving, in which form (capsule, powder, drops) and with which other ingredients? At Viterna you will find this information on every product page, exactly as it appears on the pack.

We ship directly from Austria, and you pay with secure payment methods.

When can food supplements be useful?

The foundation is always a varied, balanced diet. Food supplements can complement it in a targeted way, for example in months with little sunshine or on a vegan diet.

Two examples: vitamin D contributes to the normal function of the immune system. Vitamin B12 contributes to the reduction of tiredness and fatigue.

Food supplements are not a substitute for a varied and balanced diet and a healthy lifestyle.

How do I find the right product?

The quickest way is via a topic, an ingredient or your favourite brand:

Immune system Stomach & gut Vitamin D Magnesium Sports
