Frequently asked questions about ingredients

What does main ingredient mean?
A product is listed under the nutrient that defines it. All other nutrients it contains are listed in the full ingredient list on the product page.
Why is a product listed under several ingredients?
A product with zinc and vitamin C appears under both nutrients, so you can find it whichever one you search for.
Why can't I find a particular nutrient?
We only show areas for which we have products in our range. When a matching product is added, the area appears automatically.
Is a higher amount automatically better?
No. Many nutrients have reference values and maximum amounts. What counts is the recommended daily dose stated on the packaging.
A combination product or a single nutrient?
That depends on what you already take. Combinations cover several nutrients in one serving, single products can be dosed more precisely. You'll find both here – the exact amounts are shown on each product page.
Can I take two products with the same nutrient?
Then the amounts add up. Keep an eye on your total intake and the recommended daily dose. If in doubt, ask your doctor or pharmacist.

Food supplements are not a substitute for a balanced and varied diet and a healthy lifestyle. Do not exceed the stated recommended daily intake. Keep out of the reach of young children.
