FAQ
What makes Aqua Silica better than other silicon products?
Aqua Silica contains organic colloidal silicon in levitated water according to the Hacheney process. This special structure ensures the highest purity and optimal stability. We also do not use artificial additives, binders or preservatives – for uncompromisingly pure quality.
How is Aqua Silica taken and how long does one bottle last?
The recommended daily dose is one tablespoon (15 ml), which is simply mixed into a drink. One bottle contains 500 ml and is sufficient for 33 applications, meaning over a month of daily use.
Does the product contain artificial additives or preservatives?
No, Aqua Silica is completely free of synthetic additives, binders, or preservatives. We rely on a purely natural formula without unnecessary fillers.
Why is silicon important for the body?
Silicon is a natural component of the body and is found in blood vessel walls, cartilage, and bones. It plays an important role in the structure of connective tissue and is absorbed through a conscious diet.
How should Aqua Silica be stored?
The product should be stored in a cool, dry, and dark place. After opening, we recommend storing it in the refrigerator at 4-8 °C and using it within 30 days. Shake well before use.
