This product provides 1,410 mg of **astragalus root** per serving (3 capsules) using whole root powder. Astragalus (Astragalus membranaceus) has a long history in traditional Chinese medicine, primarily used for immune support. The clinical evidence from human trials is still limited — a handful of small RCTs suggest it may support immune cell activity and help your body manage seasonal stress on the immune system, but large-scale confirmatory studies are lacking.

You're getting whole root powder rather than a standardized extract. Most clinical trials use extracts standardized to specific compounds like astragalosides or polysaccharides, which concentrate the active components. Whole root powder delivers a broader range of plant compounds but at lower concentrations per milligram. The 1,410 mg dose is within the traditional use range, and the twice-daily dosing (2,820 mg total) keeps you at a reasonable daily intake.

If you're considering this for immune support, set your expectations based on the current evidence level, which remains preliminary. Astragalus may be worth including as part of a broader immune-support routine, but the research hasn't yet produced the large-scale confirmatory trials that would make it a high-confidence recommendation on its own.
