MAK is an herbal preparation available as a food supplement. It is being taken for its anticipated health-promoting and anti-aging benefits. MAK refers to the combination of two natural products: M4 a paste, and M5 a tablet. Combined, MAK is comprised of plants or plant parts from 24 different herbs. Sharma et al. (Pharmacol Biochem Behav, 35:767–773, 1990) showed that MAK prevents and even reverses chemically induced breast tumors in rats. We showed (JZ Fields et al, The Pharmacologist, 32:155, 1990) that aqueous extracts of MAK scavenged both OFR (superoxide) and non-radical oxidants (hypochlorous acid) in suspensions of human neutrophils without compromising the viability of the cells. In mice (C57BL/6 male, n=29/group) fed 6% MAK in the diet starting at 18 months of age, 80% of MAK mice were alive at 23 mo vs. 48% for controls (p<0.05). Body weights for control (41.5 g) and MAK mice (38.3 g) were not significantly different. In fruitflies (male, wild type, Drosophila melanogaster, n=100/group) fed 12% MAK from hatching to expiration, mean life span was significantly increased (+70%). The antioxidant properties and anti-carcinogenic properties of MAK may contribute to its anti-aging properties.
