What it does: Glycerin functions as a humectant, drawing and holding water to keep supplement products moist, stable, and flexible. When consumed, it may help support gentle hydration by drawing water into the digestive tract.
How it is used: It is frequently used in supplements to keep softgels and capsules from drying out, to stabilize liquid formulas, and sometimes to support digestive hydration or palatability.
Natural sources and supplement forms: Glycerin occurs naturally in vegetable oils such as coconut, palm, and soy, as well as in animal fats. For supplements, it is usually produced from purified vegetable oils and appears as a food-grade liquid.
Why it appears in supplement formulas: Its remarkable moisture-retaining properties preserve product freshness, ingredient stability, and texture, and make it a useful carrier for certain nutrients.
What to know before use: Glycerin is well tolerated by most people in typical amounts, but large doses or sensitivity may cause mild gastrointestinal discomfort or have a mild laxative effect.
