Astragalus
Also known as: Astragalus membranaceus, Huangqi, Milk Vetch Root, Astragalus polysaccharides (APS), Astragaloside IV, AS-IV
Effective Dosage
No established dose from provided studies
What the Science Says
Astragalus is a root herb used for centuries in Traditional Chinese Medicine. The provided research suggests its polysaccharides (APS) may improve amino acid absorption from protein supplements and support muscle function, particularly in older adults, when combined with resistance training. Early-stage lab and animal studies also point to potential anti-inflammatory, antioxidant, and anti-tumor properties, but these have not been confirmed in large human trials.
What It Doesn't Do
Not proven to cure or treat cancer in humans — lab results don't translate directly to people. Won't replace standard diabetes or thyroid medications. No solid evidence it boosts immunity on its own in healthy adults. Not a standalone muscle-builder. The multi-ingredient products studied make it impossible to credit Astragalus alone for any benefit.
Evidence-Based Benefits
No papers were provided for this analysis, so no evidence-based efficacy claims can be made. Astragalus is a traditional Chinese medicinal herb commonly marketed for immune support and anti-aging properties, but these claims cannot be verified or cited from the provided research corpus.

Absorption & Bioavailability
Unknown — no provided studies directly measured Astragalus bioavailability in humans. One study noted APS improved amino acid absorption from whey protein, suggesting gut-level activity, but absorption of Astragalus compounds themselves was not characterized.
Red Flags to Watch For
- Most promising findings come from animal or cell studies — human evidence is very limited and often involves multi-ingredient blends, making it impossible to isolate Astragalus's contribution
- No established safe or effective human dose identified in the provided studies
- Used in combination products (SQP, SH003, SHPro) alongside many other herbs — any benefits cannot be attributed to Astragalus alone
- Cancer-related claims are based entirely on pre-clinical (lab/animal) data; no human efficacy trials for cancer were provided
- Mild adverse events (GI issues, skin reactions) reported in some combination product trials
