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.
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.

Function:
1. INCREASE IN MUSCLE CREATINE LEVELS.
In order for creatine to be effective, you need to see increased levels of creatine in skeletal muscle. According to recent research, 10-40% increases in muscle creatine and PC stores have been observed with creatine supplmentation.
These results were observed after a specific “loading” protocol was observed. This protocol involves ingesting roughly .3 g/kg/day for between 5 and 7 days (roughly 20 grams a day in 5 gram increments) and 3-5 g/day following the first 5-7 day period.
While other protocols have been suggested that involve no loading phase and “cycling” on an off creatine supplementation, they have not shown to be quite as effective in maintaining increased levels of muscle creatine levels.
 
2. INCREASE IN POWER & PERFORMANCE.
Creatine supplementation appears to be the most effective legal nutritional supplement currently available in regards to improving anaerobic capacity and lean body mass (LBM). The research surrounding the ergogenic effects of creatine supplementation is extensive with hundreds of published studies looking exactly at those two outcomes. Approximately 70% of the research has reported a significant (P<.05 for the stats people out there) increase in exercise capacity, while none have reported an ergolytic effect.
In both the short term and long-term, creatine supplementation appears to enhance the overall quality of training, leading to 5 to 15% greater gains in strength and performance. In addition, nearly all studies indicate that “proper” CM supplementation increases body mass by about 1 to 2 kg in the first week of loading.
In the International Society of Sports Nutrition position stand on creatine the authors state, “The tremendous numbers of investigations conducted with positive results from CM supplementation lead us to conclude that it is the most effective nutritional supplement available today for increasing high-intensity exercise capacity and building lean mass”.
