What it does: Glycerin attracts and holds onto water, helping maintain moisture in both supplement products and, when taken orally, the digestive tract. This can help keep formulations stable and may gently support hydration.
How it is used: It is widely used to keep softgels and capsules flexible, prevent drying, stabilize liquid supplements, and occasionally to assist with hydration or improve taste and texture.
Natural sources and supplement forms: Glycerin occurs naturally in animal fats and vegetable oils such as coconut, palm, and soy. Commercial glycerin for supplements is typically purified from plant oils and supplied as a food-grade liquid.
Why it appears in supplement formulas: Its ability to retain moisture, stabilize ingredients, and act as a mild humectant or sweetener makes it valuable in maintaining the quality, texture, and shelf life of supplement products.
What to know before use: Glycerin is generally well tolerated, but can cause mild digestive discomfort or a laxative effect in high amounts, especially in sensitive individuals.
