Efficacy and safety of astragalus polysaccharides in patients with malignant tumors: A systematic review and meta-analysis
Naunyn-Schmiedeberg's archives of pharmacology (2025) · Meta analysis · n=2648
No substantial distinctions were noted between the two groups in terms of CD8 + T cell count [MD = -1.74, 95% CI (-4.66, 1.17), P = 0.242].
Effect of 12-Week Intake of Nicotinamide Mononucleotide on Sleep Quality, Fatigue, and Physical Performance in Older Japanese Adults: A Randomized, Double-Blind Placebo-Controlled Study
Nutrients (2022) · Rct · n=108
Significant interactions were observed between 5-STS and drowsiness. 5-STS of all groups on post-intervention and drowsiness of the NMN_PM and Placebo_PM groups on mid- and post-intervention showed significant improvement compared with those in pre-intervention.
Anti-inflammatory effects of nicotinamide mononucleotide (NMN) in human skeletal muscle after BFR-exercise
Journal of the International Society of Sports Nutrition (2026) · Rct · n=11
BFR-exercise increased the mitochondrial content in exercised muscle by 171% after 24 h of recovery.
The differential impact of three different NAD(+) boosters on circulatory NAD and microbial metabolism in humans
Nature metabolism (2026) · Rct · n=65
Ultimately, we propose a gut-dependent model for the modes of action of the three NAD+ precursors with NR and NMN elevating circulatory NAD+ via the Preiss-Handler pathway, while rapidly absorbed Nam acutely affects NAD+ levels via the salvage pathway.
Based on multiple meta-analyses showing adjuvant benefits for diabetic conditions. Effects appear time-dependent (>12 weeks). Studies primarily used combination therapy rather than astragalus alone.
Based on multiple RCTs showing dose-dependent increases in blood NAD+ levels. Effects vary significantly by formulation bioavailability. Most studies used 250-1000mg doses.
AI-estimated from published studies. Interpret as directional guidance.
Astragalus has a higher evidence score (5/10 vs 5.5/10) and wins in 2 of 3 categories.
For healthy aging, NMN has a higher relevance score (85 vs 35).
No known interactions between Astragalus and NMN have been documented in our database. However, always consult a healthcare provider before combining supplements.
