Astragalus Root is described by Glycens as an adaptogenic root traditionally used to support vitality and the body's natural metabolic balance. Ingredient-level research includes a 2024 randomized, double-blind, placebo-controlled study in Nutrients on telomere length in a middle-aged population, a review in Archives of Pharmacal Research on astragalus polysaccharide's immunomodulatory effects, and a 2023 paper in the International Journal of Biological Macromolecules on its anti-inflammatory activity. This research covers astragalus generally, not GlycoAid's specific extract, form, or amount, which the brand does not disclose.
