Anti-Fatigue Caps are designed primarily for ammonia reduction in long distance events, but many of the nutrients in the formula are excellent for helping counteract everyday fatigue, even chronic fatigue symptoms. During extended endurance exercise the body accumulates excess ammonia from protein metabolism, which interferes with glycogen production, disrupting energy output. Anti-Fatigue Caps are a one-of-a-kind product combining three well-known ammonia-scavenging nutrients. Usage information 2-4 capsules one hour prior to training. This would provide an initial dose of 500-1000 mg magnesium/potassium aspartate, 200-400 mg citrulline, and 280-560 mg OKG, an excellent dose at the onset of an endurance workout or race. An additional 1-2 capsules each hour, at the two-hour mark and beyond, during extended endurance sessions is also suggested. Ingredients per capsule: Potassium Magnesium Aspartate 250 mg, L-Citrulline 100 mg, OKG (Ornithine alpha Ketoglutarate) 140 mg, Enzyme Enhancement System (A proprietary blend of protease and phytase) 10 mg. Other ingredients: Stabilized Rice Bran, Vegetable Capsules (pullulan and water).
