Eclipse 2000 Glutamine caps contain the free form amino acid L-Glutamine. Maximum growth and proliferation of most cell types occurs with adequate glutamine stores. Glutamine plays a key part with the branched chain amino acids (BCAA) in muscle energy metabolism and the over training syndrome of athletes. The relative mild stress of weight training can result in a significant decline in skeletal muscle free glutamine. Over training is associated with even greater decreases in muscle glutamine levels. The supplementation of L-Glutamine can cause an anti-catabolic effect and contribute to cell volumizing.
