"Creatine Nitrate"

Louise Deldicque, Marc Francaux
PURPOSE OF REVIEW: The purpose of this article is to collect the most recent data regarding the safety of well-known or emerging dietary supplements used by athletes. RECENT FINDINGS: From January 2014 to April 2016, about 30 articles have been published in the field. New data show that 90% of sports supplements contain trace of estrogenic endocrine disruptors, with 25% of them having a higher estrogenic activity than acceptable. About 50% of the supplements are contaminated by melamine, a source of nonprotein nitrogen...

BACKGROUND: Creatine monohydrate (CrM) and nitrate are popular supplements for improving exercise performance; yet have not been investigated in combination. We performed two studies to determine the safety and exercise performance-characteristics of creatine nitrate (CrN) supplementation. METHODS: Study 1 participants (N = 13) ingested 1.5 g CrN (CrN-Low), 3 g CrN (CrN-High), 5 g CrM or a placebo in a randomized, crossover study (7d washout) to determine supplement safety (hepatorenal and muscle enzymes, heart rate, blood pressure and side effects) measured at time-0 (unsupplemented), 30-min, and then hourly for 5-h post-ingestion...

BACKGROUND: Creatine monohydrate has become a very popular nutritional supplement for its ergogenic effects. The safety of creatine monohydrate has previously been confirmed. However with each novel form of creatine that emerges, its safety must be verified. Therefore, the purpose of this study was to examine the safety of a novel form of creatine, creatine nitrate (CN), over a 28 day period. METHODS: 58 young males and females (Pooled: 24.3 ± 3.9 years, 144...

Muscle creatine kinase (MCK; EC2.7.3.2) is a 86 kDa homodimer that belongs to the family of guanidino kinases. MCK has been intensively studied for several decades, but it is still not known why it is a dimer because this quaternary structure does not translate into obvious structural or functional advantages over the homologous monomeric arginine kinase. In particular, it remains to be demonstrated whether MCK subunits are independent. Here, we describe NMR chemical-shift perturbation and relaxation experiments designed to study the active site 320s flexible loop of this enzyme...
