Creatine News and Research

RSS

Creatine is an endogenous amino acid which is synthesized from simpler amino acids, namely glycine, arginine and the sulfur-containing amino acid methionine. Approximately 95 percent of creatine in the body is stored in skeletal muscle.

Scientists discover metabolite fueling aggressive brain tumor growth

Virtually all high-grade, aggressive gliomas in adults accumulate massive amounts of a metabolite called guanidinoacetate (GAA) that overstimulates nearby neurons and promotes tumor growth, according to new research from scientists at Children’s Medical Center Research Institute at UT Southwestern (CRI) published in Cell.

Zidesamtinib shows strong activity in TKI-naive ROS1-positive non-small cell lung cancer

New results from the global Phase I/II ARROS-1 trial showed clinically meaningful activity with zidesamtinib in patients with advanced or metastatic ROS1-positive non-small cell lung cancer (NSCLC) who had not previously received a tyrosine kinase inhibitor (TKI).

Women use creatine differently from men, survey reveals

A cross-sectional survey of 2,094 current or recent creatine users found that women were more concentrated in shorter-duration use groups than men and reported different supplementation goals, information sources, and knowledge patterns. Women were less likely to cite athletic performance and more likely to cite healthy aging as a goal, while researchers cautioned that the survey design cannot explain why these differences exist.

Trial identifies 4 grams a day as the tested safe level for L-tyrosine in healthy men

A randomized, crossover trial in healthy adult men found that 4 weeks of L-tyrosine supplementation at doses up to 4 g/day did not cause clinically meaningful changes in safety markers, diet, blood pressure, or body measures. The highest tested dose, 4 g/day, was identified as the no-observed-adverse-effect level under the study’s four-week conditions, although broader and longer-term studies are still needed.

Can supplements slow Parkinson’s disease? Review reveals where the evidence stands

Dietary supplements are widely used by people with Parkinson’s disease, but this review finds that none have yet been proven to slow disease progression. Biotics, nicotinamide riboside, and omega-3 fatty acids combined with vitamin E show the most promise, but larger, longer, and better-designed trials are needed.
