A Baylor University study has found that a popular nutritional supplement that is marketed to lead to greater muscle strength through increasing blood flow to the muscle does not increase blood flow as claimed on the bottle. In recent years, various nutritional supplements have been developed containing arginine-alpha-ketoglutarate (AAKG), which is alleged to increase nitric oxide production thereby resulting in "vasodilation," the widening of blood vessels and increased blood flow to the muscles. The AAKG supplement-enhanced blood flow to working muscles during resistance exercise is alleged to provide increased muscle strength than just exercise alone.
