Summary
The purpose of this study was to evaluate the effects of daily glycine supplementation on metabolic health and cognitive performance in older adults. Over a period of six months, participants received 1,000 mg of glycine per day to determine if this amino acid could improve markers of insulin resistance, glucose metabolism, and cognitive functions such as memory and executive tasks. The research aimed to identify whether this nutritional intervention provides a safe and effective strategy to support healthy aging, focusing on the link between metabolic balance and brain health in the elderly population.
