Deer antler velvet is the tissue that covers the bone and cartilage that develop into deer (and elk) antlers. It has been harvested for centuries and used traditionally to increase strength, boost the immune system, and counter the effects of stress. Now it’s promoted to improve athletic performance; raise testosterone levels to increase sex drive, fertility and erectile function in men; as well as to reduce the signs of aging and treat problems ranging from high cholesterol, high blood pressure, asthma and osteoporosis to migraine headaches, indigestion, and many more.
The truth? While research is limited, there’s nothing to suggest that deer antler velvet (or deer antler spray in the supplement form) actually does what it claims. In fact, there are two published studies (in real scientific journals, you can see them here and here) that suggest deer antler velvet does not (I repeat, does not) even elicit a hormonal response. What’s more, it also did not increase muscular strength or aerobic power.
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.
