New Zealand research reports that although the mechanism is unknown, deer antler velvet shows strong anti-inflammatory effects. Recent clinical tests suggest oral ingestion of glycosaminoglycan-peptide complex, or components such as chondroitin sulfate and glucosamine sulfate — both found in deer antler velvet — may help stimulate cartilage repair.
Repeated studies have been conducted on the interactions of Velvet Antler and hormones, and all studies have found that this supplement has failed to increase circulating hormone levels. One study found a highly variable increase in power output, which is antagonized by another study suggesting no significant increase in power. For the purposes of performance enhancement, the evidence does not currently support Velvet Antler as a supplement.
Supplements are best used in situations where an individual is unable to get their nutrients from their diet. Perhaps an individual has an allergy or intolerance, for example lactose. They are unable to consume milk products which in turn limits their ability to get sufficient calcium and vitamin D from their diet. In that case, a supplement makes sense.
