Many people think of whey protein as a supplement only used by athletes wanting to increase their muscle mass. But evolving research suggests the branched-chain amino acids (BCAAs) leucine, isoleucine, and valine and other fractions found in whey can mimic the longevity benefits of calorie restriction (CR)!
Searching for CR-mimetics, scientists recently investigated the life span effects of a balanced amino acid mixture high in the branched chain amino acids found in whey.1,2 In keeping with earlier studies on other organisms,3,4 they found branched chain amino acids significantly increased life span in mice.2
This “superfood” provides all 18 amino acids, naturally occurring bioactive components such as immunoglobulins and lactoferrin, and a cysteine concentration over 4-fold higher than other proteins—all in a highly absorbable form.5-8 And whey is one of the greatest foods for maximizing glutathione,9,10 the endogenous antioxidant that quenches oxidative stress11,12 to inhibit diseases of aging.10,13-15
In addition to expanding life span, whey has been found to reduce muscle wasting in the elderly, reduce the risk of diabetes, inhibit cancer development, and defend against cognitive decline.16-19
Given all these benefits, whey has now been substantiated by significant science as a powerful super food in the quest for healthy longevity.
