The growing market has bred plenty of competition. A company called Now Foods is now making deer antler velvet lozenges. GNC just started selling deer antler velvet capsules called New Vigor from a company called Vitalast and Amazon.com has more than 30 products will deer antler velvet in it including the raw powder from New Zealand, where the most coveted deer velvet is harvested.
Generally researchers agree that deer antler velvet protects, strengthens and restores the body's functions that are out of balance. In other words, it can act as an adaptogen on the human body, helping where it is needed. Studies suggest that deer antler velvet may have beneficial effects related to: increases in muscular development, strength and endurance; improved recovery; prevention and reduction of inflammation; improvement of sexual health; reduction in blood pressure; improvement in bone and joint health; stimulation of the immune system; and more.
Fat Metabolism* -Besides containing a plethora of nutrition, such as peptides, growth factors and important minerals, which may help to prevent cravings, deer antler velvet also contains ursolic acid, which may be beneficial for increasing fat metabolism, we can, with a little effort and motivational boost, achieve a leaner and firmer physique.* Additionally, research in other fields suggests that it may be responsible for a smaller waist.*
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.
Companies attributing health claims from using dietary supplements of velvet antler have received warning letters from the US Food and Drug Administration (FDA) concerning the sale of encapsulated powders connected to their marketing claims. The claims were in violation of the United States Food, Drug and Cosmetic Act [21 USC/321 (g)(1)] because they "establish the product as a drug intended for use in the cure, mitigation, treatment, or prevention of disease" when velvet antler has no such scientific evaluation. Additionally stated by the FDA, velvet antler was "not generally recognized as safe and effective for the referenced conditions" and therefore must be treated as a "new drug" under Section 21(p) of the Act. New drugs may not be legally marketed in the United States without prior approval of the FDA. As of 2018, it is legal to sell velvet antler powder, extract or spray in the U.S. as a dietary supplement as long as no disease treatment claims are made and the label bears the FDA disclaimer: "This product has not been evaluated by the FDA. It is not intended to diagnose, treat, cure or prevent any disease."
