Document Summary
Benefits of l-carnitine: acts as a vasodilator in peripheral tissues, may enhance regional blood flow and oxygen delivery, might improve oxygen supply to injured tissue and promote clearance of muscle damage byproducts. Chromium: for athletes with chromium-deficient diets, prudent use of chromium supplements seem appropriate, poor intestinal absorption of chromium chloride is a main hindrance to effective supplementation, chromium picolinate is absorbed better by the body. Negative effects of chromium: competes with iron for binding to transferring, excessive dietary chromium inhibits zinc and iron absorption. Improves repetitive performance in muscular strength and power activities: augments short bursts of muscular endurance, provides for greater muscular overload to enhance training effectiveness. Risks associated with creatine supplementation: short-term use in healthy men has produced no detrimental effect on blood pressure, plasma creatine, plasma ck activity, or the renal response. Individuals with suspected renal malfunction should refrain from creatine supplementation.
