Beyond its natural sweetness that allows us to create a great taste without sugar, glycine is backed by clinical studies showing remarkable benefits during fasting: 27% less muscle loss and 14% accelerated fat loss. While commonly known as a sleep supplement, glycine's advantages extend throughout active hours, supporting energy production and metabolic health.
