Deer antler velvet can help slow the aging process and possibly even increase longevity due to the IGF-1 present in deer antler velvet. Aging occurs because our DNA becomes damaged throughout our lives and the damages accumulate over time. The damaged nuclear DNA can either directly cause the aging process by increasing cell dysfunction or it can indirectly cause the aging process by increasing programmed cell death (apoptosis) or increasing the number of cells which are unable to divide any further (cell senescence).
A systemic review on human interventions makes note of a study conducted on patients of osteoarthritis (Edelman et al. 2000; cannot be located online) which found improvements in joint pain symptoms relative to baseline in the Velvet Antler group and not placebo, although a lack of information on blinding and randomization precludes results that can be drawn from this study.
