The safety and health of our customers is our priority.
We have carefully chosen silicon dioxide because on the one hand it ensures the dissolution of the product and on the other hand it protects the components of the product from oxidation.
We have chosen a form of silicon (synthetic amorphous silica; > 100 nm) that is well proven for nutritional supplements.
Silicon dioxide is found in nature and in many foods we eat every day, such as green leafy vegetables, whole grains, beets and sprouts such as alfalfa.
According to EFSA's 2019 re-evaluation, there are no toxic effects from common use for humans if a form and size like ours is chosen. We comply with the given recommendation not to exceed 50 mg per kg body weight, we used only under 1 g, which is about ⅓ of the recommended safe daily amount for a normal-weight adult. It was shown in studies that exposure of up to 9 grams per day showed no negative effects.
The risks raised from a justified scepticism about the lack of regulation of the form and size of silicon dioxide applied, as well as results from animal studies on forms we don't use, and the lack of long-term studies of the latter. We keep an eye on this and regularly monitor the study situation. That means, we always take care of the safety of our customers.
