Favorable safety and promising impact of supplemental creatine on human well-being and functioning emanated from plenty of small-sampled interventional studies perhaps suggest a need for recommending creatine to the general public.
The participants who consumed more than 0.95 g of creatine per day (3rd and 4th quartiles of creatine intake) were found to have higher scores on the cognitive functioning test as compared to their peers with lower creatine intake (1st and 2nd quartiles).
The health and ergogenic effects of dietary taurine, creatine, carnosine, anserine, and 4-hydroxyproline are expected to reverse the drastic decline in consumption of red meat (e.g., beef) in the U.S. due to an inadequate understanding of animal-source foods to provide functional amino acids, peptides, and creatine.
