Glycine is the simplest amino acid, abundant in gelatin, and it earns its place in this formula through a research angle most people have never heard of.

What it is

Glycine is the smallest and structurally simplest of the twenty standard amino acids. It's abundant in collagen and gelatin, and the body can also synthesize it internally, meaning it isn't a strictly "essential" nutrient in the way some other amino acids are.

Why it's included here

Research interest in glycine within the metabolic-support category centers on its studied role in gut-hormone signaling and glucose metabolism — some evidence suggests glycine may influence insulin secretion and glucose handling after meals.

What the evidence actually supports

It's important to be precise about the state of this research: most of the relevant studies use doses considerably higher than what a food-derived gummy provides, and human evidence at food-derived doses remains preliminary. This is one of the less-established ingredients in the formula on a pound-for-pound evidence basis.

Why it's still a reasonable inclusion

At the doses present in a gummy, glycine carries essentially no risk and a plausible, if unproven, mechanistic rationale — a low-cost, low-risk addition to a formula built around several complementary angles rather than one single proven mechanism.
