It is also a fast inhibitory neurotransmitter.[MeSH]FabaceaeThe large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of beans belong to this family.[MeSH]

Overview

Creatine is a nitrogenous organic acid and plays roles such as fast phosphate energy buffer to replenish ATP, osmolyte, antioxidant, neuromodulator, and as a compound with anabolic and ergogenic properties in muscle. Creatine is an essential metabolite in the creatine kinase reaction, which plays a critical role in maintaining normal cardiac function.

Toxicity

creatine supplementation is safe and effective for treating idiopathic inflammatory myopathies, but no pediatric study has been conducted. The vague regulatory status of creatine supplements hinders effective monitoring of adverse events.

Dosage Studied

creatine is considered a medicinal product by the Council Directive 65/65/CEE. When dosed at 300 mg/kg/day for 3 months, cyclocreatine-related mortality, convulsions, and multi-organ pathology were observed in wild-type mice. There were no adverse findings in creatine transporter-deficient mice.
