In a double blind study (Edelman, 2000), 54 patients with arthritis in the knee were given deer antler velvet or a placebo and assessed at 1, 3 and 6 months. Patients treated with deer antler velvet showed improvement in pain and physical global assessment at 3 and 6 months. No significant improvement was observed for the placebo group for any of the parameters examined.
Insulin-like Growth Factor 1 (IGF-1) is an anabolic molecule which appears to induce growth of the antlers themselves,[31][32] although testosterone may be the primary growth factor.[33] Currently, there is no evidence that serum IGF-1 is increased following Velvet Antler ingestion with one study using 1.5g of Velvet Antler for 11 weeks failing to increase serum IGF-1.[26]

The IGF-1 in deer antler velvet can help increase the body's natural healing by affecting cell repair and growth. When an injury or surgery occurs that leaves a wound on the body, the wound is healed naturally by the cells which line the wound. Those cells multiply and rejoin over time. Using deer antler velvet can help promote faster cell repair and growth so that the wound can heal at a faster rate which means less time being injured or sore.


Deer antler products contain mostly amino acids (that form proteins) along with growth factors, which are poly-peptide bonded amino acid chains. (4) The most abundant growth factor is IGF-1. However, it isn’t a factor found in these products. Depending on the specific brand, deer antler spray/powder/capsules may contain amino acids and growth factors including: (5)
L-Arginine: An amino acid usually found in red meats that is important for the body’s ability to manufacture proteins. L-Arginine has been used to treat conditions like high blood pressure, congestive heart failure, blocked arteries, and erectile dysfunction. L-Arginine is safe for most people, however it should not be taken by women that are pregnant or breastfeeding.
