This liquid extract delivers 665 mg of **astragalus root** per serving via an alcohol-water extraction. Astragalus is an adaptogenic herb with moderate evidence for supporting your body's natural immune defenses. The liquid tincture format means faster absorption compared to capsules, since the active compounds begin absorbing in your mouth and stomach lining.
At the suggested 2–4 servings per day, you're getting 1,330–2,660 mg of extract daily, which aligns with the ranges seen in clinical studies on immune function. The dual-solvent extraction method (cane alcohol and water) pulls out both types of active compounds — the water-soluble and alcohol-soluble fractions — giving you a broader range than either method alone.
One thing to understand: most astragalus research uses extracts standardized to specific active compound levels, and this product doesn't specify those percentages on the label. That makes it harder to know exactly how much of the key compounds you're getting per dose. If your goal is immune support, taking the full suggested dose between meals gives you the best chance of reaching a meaningful intake.
