The Burgerstein preparation is a classic vitamin preparation. Depending on scientific studies, the benefit is low to negative, except in cases of clearly proven deficiency symptoms. And Strath is an alternative product made from herbal yeast, but sweetened.

If you eat a vegan diet, yeast can be useful (B vitamins, B12 is often no longer available in sufficient quantities because it is usually in the "dirt"). However, I would rather use unsweetened yeast flakes. The Burgerstein preparation, and all other multivitamin preparations, seem to me to be unnecessary; they simply make money with the old desire for the miracle pill. There is only one thing that really helps: a healthy diet, exercise and enough sleep.
