Ginsenoside Re is a major bioactive saponin in Panax ginseng, and it’s often the first compound researchers look at when studying ginseng’s cardiovascular and metabolic effects. It’s a protopanaxatriol-type ginsenoside, with a structure that includes four sugar residues — that’s what makes it water-soluble and easily absorbed in the gut.
Synonyms: Ginseng saponin Re, Panaxoside Re, (20S)-Protopanaxatriol 6,20-bis(glucoside), Ginsenoside Re (CAS 51542-56-4)
You won’t find Re in significant amounts in most commercial ginseng extracts — it’s often discarded during processing. The richest sources are fresh ginseng roots and ginseng berries, where Re can make up 1-2% of the dry weight. Our raw material is carefully selected Panax ginseng cultivated in Jilin, China, harvested at optimal maturity to maximize Re content.
The key advantage of Re over other ginsenosides is its oral bioavailability. The sugar chains protect it from stomach acid, and once in the intestine, it’s partially metabolized to Rg1 and Rh1, which are even more active. Studies show that Re is rapidly absorbed and reaches peak plasma levels within 1-2 hours — that’s why formulators prefer it for fast-acting ginseng supplements.
Ginsenoside Re has been used in traditional medicine for centuries, and modern research confirms its safety profile. Clinical studies have used doses up to 100 mg per day without adverse effects. It’s particularly well-studied for supporting cardiovascular function, insulin sensitivity, and neuroprotection. Unlike some synthetic drugs, Re works through multiple pathways, which makes it a versatile ingredient for wellness products.
As consumers shift toward natural, evidence-based ingredients, Ginsenoside Re is gaining traction in sports nutrition, anti-aging formulas, and metabolic health products. It’s often paired with other ginsenosides like Rb1 and Rg1 to create a full-spectrum ginseng extract. Our Re is manufactured in a GMP-certified facility, with rigorous quality control from raw material to finished powder. Every batch is tested for purity, heavy metals, and microbial limits, and ships with a complete COA.
