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.
Russian and Japanese researchers have conducted experiments using deer antler extract and found that it appears to lower blood pressure in both human subjects and laboratory animals. A series of clinical case studies (Albov, 1969) were conducted in which the effects of Pantocrin on cardiac patients were assessed. In one test involving 32 subjects with high blood pressure caused by cardiac disease, early onset menopause or obesity, blood pressure was lowered in 81% of patients. In another study involving 13 patients with hypotension caused by disorders of heart muscle activity, blood pressure was lowered for 84% of patients.
To be clear, some doctors and researchers have stated that they feel deer antler spray is unlikely to cause any significant benefits. This is because it only provides very small amounts of IGF-1, some of which may not even be fully absorbed. However, studies do show that higher doses, or using very high-quality supplements, may contribute to some improvements in performance, body composition, etc. IGF-1 itself has been studied extensively. It can certainly change the way the body looks and operates. Whether or not the role of IGF-1 in the body will translate into any real benefits when obtained from deer antler products will depend on the specific person and dosage used.
The harvesting of deer antler velvet can be a painful process, as the velvet tissue contains an abundance of nerves and bleeds profusely if cut or removed. Dr. Low Dog says she has no problem with harvesting velvet from deer killed for food, but is concerned that shortcuts will be taken should demand for the supplements continue to grow. She notes that the United Kingdom has banned the removal of deer antler velvet under its welfare-of-livestock regulations, unless the antlers have been damaged or most of the velvet has been shed.
Deer antler velvet can play a pivotal role in helping to not only relieve the symptoms of diseases that affect joints, such as osteoarthritis, they can possibly eliminate them entirely. The way it may do this is through the introduction of chondroitin sulfate and glucosamine sulfate into the body. Both of these compounds are abundant in deer antler velvet.
