Effective Dosage
No established dose from provided studies
What the Science Says
AstraGin is a patented blend of extracts from Astragalus membranaceus and Panax notoginseng, developed by NuLiv Science. It is marketed as a bioavailability enhancer — meaning it is added to supplements with the claim that it helps your gut absorb other nutrients more efficiently. The proposed mechanism involves activating certain transporter proteins in the intestinal lining, but this has primarily been studied in cell and animal models, not in robust human clinical trials.
What It Doesn't Do
Not proven to meaningfully boost muscle gains or athletic performance in humans. No solid clinical evidence it increases absorption of every nutrient it's paired with. Being in 679 products doesn't mean it's been clinically validated. The manufacturer's own in-house data is not a substitute for independent peer-reviewed trials.
Evidence-Based Benefits
Patented blend of Astragalus and Panax notoginseng. Some studies show improved nutrient absorption.

Absorption & Bioavailability
Unknown — AstraGin is itself claimed to enhance bioavailability of other ingredients, but its own absorption and the real-world magnitude of its effect in humans has not been established by independent published clinical trials.
Red Flags to Watch For
- Nearly all supporting evidence comes from the ingredient's manufacturer (NuLiv Science), not independent researchers — a major conflict of interest.
- Only 1 indexed PubMed paper found, and it is an EFSA safety review, not an efficacy trial — there are essentially no published human clinical trials on AstraGin.
- Widely used in 679+ supplement products despite a very thin evidence base — popularity does not equal proof.
- Doses used in products vary widely with no established human effective dose from independent research.
- Often added to justify premium pricing on supplements without meaningful evidence of benefit to the consumer.
