Quercesome is a high-profile molecular complex of quercetin phospholipid and vitamin C. High-purity quercetin is surrounded by a special phospholipid layer, which drastically increases the bioavailability of the molecule. In the complex, quercetin meets the finest acerola fruit powder, which is particularly rich in vitamin C. In this combination, the vital substance acts as a bio-enhancer that further improves the absorption of the molecule. The molecule quercetin is an important representative of the group of polyphenols and flavonoids, which are among the secondary plant substances. Quercetin is referred to as the king of flavonoids. This royal attribute is no coincidence, as the molecule is the focus of the latest research with promising results.
