Key Benefits of Soy Isoflavones Powder:
- Bidirectional Regulation Mechanism: As a natural phytoestrogen, its structure is similar to that of human estrogen. It acts as a supplement when estrogen levels are low; when estrogen levels are too high, it competitively binds to receptors, achieving gentle and safe bidirectional regulation.
- Natural Origin and High Safety Profile: Extracted from non-GMO soybeans, it is well-tolerated at recommended doses. It possesses antioxidant activity, helping to neutralize free radicals and delay cellular aging.
- High Bioavailability: The powder form facilitates use in various dosage forms. After conversion by gut microbiota, it is efficiently converted into the active aglycone form, significantly enhancing absorption and utilization.

- Alleviates Menopausal Symptoms Daily intake can reduce symptoms such as hot flashes, night sweats, and insomnia. Suitable for women in perimenopause and postmenopause experiencing a decline in estrogen levels.
