Conventional folic acid, used in many food supplements, is a synthetic product that does not occur in nature in this form. The Metafolin® we use provides active folate as L-methylfolate (L-5-MTHF), which is bound to a calcium salt in a special crystalline type I form and therefore enables excellent absorption by the body.
When selecting this ingredient, we paid particular attention to the stability and the specific crystal form of the salt, in addition to a purity of at least 99.9% of the active (6S) isomer. While many products on the market contain mixed forms with the inactive (6R) isomer, which cannot be utilised by the body, Metafolin® offers an optimised form for efficient utilisation. The patented premium folate Metafolin® features a particularly high absorption rate: studies show that this form can be absorbed into the blood at a rate of 76%, whereas other salt types sometimes achieve much lower values.
Folate contributes to normal blood formation, normal amino acid synthesis and normal psychological function. It also supports the normal function of the immune system, contributes to the reduction of tiredness and fatigue and has a role in cell division. Folate is particularly important during pregnancy, as it contributes to maternal tissue growth. Furthermore, it contributes to normal homocysteine metabolism.
The only other ingredient we use is premium gum arabic as a plant-based carrier. Our gum arabic comes from sustainable and resource-conserving cultivation. For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.
