Even sellers of deer antler products doubt that the products could deliver IGF-1. "IGF-1 is very unstable," Dean Nieves of Florida-based Bio Lab Naturals told the Baltimore Sun. "It could not exist outside of a very controlled environment." Nieves' company therefore markets the product as a nutritional supplement. "It is just packed with nutrients," he said.
Studies have found that deer antlers themselves contain a highly concentrated amount of essential trace minerals, fatty acids, amino acids and growth factors that can all support the immune system. This includes the gastrointestinal tract, where the majority of the immune system is found. Antlers contain minerals such as: calcium, phosphorus, magnesium, iron, potassium and sodium in addition to numerous minor components.
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.
