Superfluous to risky – dietary supplements fail at Stiftung Warentest. Dietary supplements are not a good idea for osteoarthritis.
All of the products tested are unnecessary, and a large number are even risky. The prices for a daily ration varied greatly, from 14 cents to 2.18 euros.

The funds are therefore most likely unnecessary and therefore a waste of money.
