Vitamins & Supplements

What is in the Energy Support Formula?
The formula is composed of Eleuthero, Cordyceps and Ashwagandha, all traditional herbs which may give those energy levels the boost you need. Eleutherococcus senticosus (commonly referred to as Siberian Ginseng) is a plant in the ginseng family that has been used for centuries as an adaptogen. Cordyceps, a medicinal mushroom, is highly prized in traditional Chinese medicine (TCM) as a stamina-boosting tonic. Ashwagandha, another tonifying herb that is sometimes called Indian Ginseng, is used in the Ayurvedic medicinal tradition as a general tonic to increase energy. This unique formula is free of stimulants such as ephedra and caffeine.

What is an adaptogen?
An adaptogen or tonic is an herb or nutrient that is thought to increase the body?s general resistance to stress of all kinds.

"I'm a great believer in tonic herbs -- nontoxic natural products that increase energy and resistance to stress of all kinds."
Andrew Weil, M.D.
