children and adolescents should consume a total (diet plus supplements) of 1,300 mg/day of calcium.
For example, most infants with pulmonary hypertension have an increased level of asymmetric dimethylarginine (ADMA- an inhibitor of nitric oxide production) in their blood. The easiest, most efficient method of combating this condition is to supplement with L-arginine, which overcomes ADMA's nitric oxide inhibition.
Although safe, citrulline does not directly convert to nitric oxide, but instead is recycled to L-arginine (an ATP-dependent process), which then converts to nitric oxide. Ferid Murad, MD, PhD, Nobel-prize winner for his research on nitric oxide, has said the use of L-citrulline to increase nitric oxide is only marginally effective.
Common sense says toss out the Viagra, the BiDil and the citrulline, and utilize L-arginine. Change bad medicine to good medicine and ignore the hype.
