Deer Antler Extract
Deer antler extract may contain the hard base of deer antlers in powdered form, the velvety covering on deer antlers, or some combination of the two. Deer antler base has a long history of use in traditional Chinese medicine, as documented in classical Chinese texts dating to more than 2,000 years ago. Deer antler velvet is a newer addition to the dietary supplement market, becoming more popular only in recent years.
