Although we acknowledge that there are many valid definitions for aging, we suggest that biological aging be defined as the progressive, event-dependent decline in the ability to maintain biochemical/physiological function. Longevity is the length of the life span independent of the biological aging process. In addition to following a healthy diet and lifestyle, taking certain supplements may help slow the aging process and promote a long, healthy life. Curcumin, collagen, CoQ10, crocin, and vitamin C are just a few of the substances that have been shown to offer age-supportive effects.
