Creatine nitrate is a form of creatine where the molecule is found to a nitrate group, and this form of creatine is currently being tested to see its worth as a nutritional supplement.
Only one study has been published thus far, indicating that creatine nitrate has about 10 times the water solubility as does either creatine monohydrate or buffered creatine. In other words, 10 times as much creatine is needed in a certain volume of water for a precipitate (sediment) to form; this likely means that creatine nitrate would be more palatable than creatine monohydrate when drank.[1]
Currently, no studies on creatine nitrate in regards to exercise performance or strength have been conducted. Claims of creatine nitrate being superior to creatine monohydrate are unsupported by the literature.
Creatine nitrate supplementation is likely to be simply creatine supplementation plus nitrate supplementation.
Creatine nitrate is more soluble than creatine monohydrate, a similar property that other forms of creatine have (micronized creatine, creatine malate or citrate) and currently does not have any studies supporting its usage over other forms of creatine.
