By selecting the appropriate form of vitamins and minerals, the absorption in the body can be significantly increased. Therefore, we use bioavailable forms, in this case - magnesium citrate, magnesium bisglycinate and zinc bisglycinate. Moreover, the molecular structure of the chelate, consisting of two amino acids, fulfils two key functions - excellent absorption and good tolerability in the gastrointestinal tract. And how does the chelate work? Two glycine molecules surround the mineral and protect it from reactions with other food components, such as phytates or fibre, during transport through the gastrointestinal tract.
