Description

Astragalus polysaccharides (APS) are bioactive molecules isolated from the root of Astragalus membranaceus, a traditional Chinese medicinal herb. APS are studied for their immune-enhancing, anti-inflammatory, and antioxidant properties.

benefits
Main effects with level of evidence
Moderate
Note on evidence

Preclinical and early clinical studies show promise for immune support and inflammation reduction, but more large, high-quality human trials are needed.

Supports Immune Function

Moderate

APS appear to enhance immune cell activity, including macrophages and T cells, and may help counter immunosuppression.

Reduces Inflammation

Moderate

Studies indicate APS lower inflammatory cytokines and may reduce symptoms in inflammatory conditions.

Provides Antioxidant Protection

Moderate

APS show strong free-radical scavenging effects, reducing oxidative stress.

Particularly relevant for: people at risk of oxidative stress

Supports Cardiovascular Health

Limited

Preclinical models and some clinical evidence suggest APS protect heart tissue and improve cardiac function after ischemia.

Particularly relevant for: those at risk of cardiovascular disease
