Why It Works
Benefits
Kikkoman's formula delivers comprehensive support through carefully selected ingredients that work together for women's wellness.
Supports Hormonal Balance Naturally
Soy isoflavone aglycone, particularly genistein, has a structure similar to estrogen and may help support hormonal balance during menopause. Unlike standard isoflavones that require gut bacteria conversion, the aglycone form is directly absorbed - meaning consistent results regardless of individual digestive variations.
Research-backed ingredientPromotes Bone Health & Density
The formula combines soy isoflavone aglycone with vitamin D3 (30.0mcg) and works synergistically to support calcium absorption and bone mineral density. This is particularly important during menopause when bone loss may accelerate due to hormonal changes.
Synergistic nutrient combinationProvides Antioxidant Support
200mg of grape seed-derived proanthocyanidin provides powerful polyphenol support - equivalent to 4-6 glasses of red wine. This king of polyphenols supports healthy aging and helps maintain youthful vitality at the cellular level.
Polyphenol research-backedComprehensive Women's Wellness
Beyond isoflavones, the formula includes folic acid (400mcg) for cellular health support. This comprehensive approach addresses multiple aspects of women's health during the transitional years, supporting overall wellness from within.

How It Works
Understanding how Kikkoman's isoflavone supplements support your body's natural processes during menopause.
Aglycone Form: Direct Absorption Without Conversion
Kikkoman's aglycone form bypasses this requirement entirely - the isoflavones are absorbed directly in their active form. This means consistent benefits for everyone, regardless of individual gut microbiome composition.
Key advantage:
- 50%+ genistein content - the most supportive form for women
- Direct absorption without bacterial conversion needed
- Consistent effectiveness for all users
Four Synergistic Components for Women's Health
Soy Isoflavone Aglycone (25mg) - Core hormonal support
Proanthocyanidin (200mg) - Antioxidant protection
Folic Acid (400mcg) - Cellular health support
Vitamin D (30.0mcg) - Enhanced calcium absorption
These ingredients work synergistically rather than in isolation.
Proanthocyanidin: The King of Polyphenols
Just 2 tablets provide polyphenol content equivalent to 4-6 glasses of red wine. This supports healthy aging and helps maintain a youthful, vibrant lifestyle - complementing the hormonal support from soy isoflavones.

Ingredient Research Highlights
SOY ISOFLAVONE AGLYCONE
Soy isoflavones, particularly in the aglycone form, have been studied for their potential to support women's health during menopause. The aglycone form (genistein, daidzein, glycitein) is the active form that can be directly absorbed without requiring enzymatic conversion by intestinal bacteria.
Nutritional science research on phytoestrogensPROANTHOCYANIDIN
Grape seed-derived proanthocyanidins are oligomeric proanthocyanidins (OPCs) studied for their antioxidant properties. Research suggests they may support cardiovascular health and healthy aging through their potent free-radical scavenging activity.
Polyphenol researchVITAMIN D3
Vitamin D3 supports calcium absorption and bone health. During menopause, adequate vitamin D becomes increasingly important for maintaining bone mineral density. The 30.0mcg in this formula supports daily nutritional needs.
