Product Overview
Soy Isoflavones are plant compounds derived from Glycine max (soybeans), concentrated and standardized to deliver a consistent level of the primary isoflavones — genistein and daidzein. These compounds belong to a class of plant-based phytoestrogens and are among the most studied ingredients in the women's hormonal-health supplement category.
For supplement manufacturing, soy isoflavones are extracted from soybeans or soy germ and standardized into a powder that can be encapsulated to deliver a specific, measurable isoflavone dose per serving — a key differentiator from unstandardized soy-derived ingredients.
Key Considerations for Formulating with Soy Isoflavones
- Standardization to a specific total isoflavone percentage supports a clear, verifiable label claim
- Frequently combined with red clover, black cohosh, or calcium in women's midlife wellness formulas
- A soy-derived ingredient, relevant to labeling for soy-free or allergen-conscious product lines elsewhere in a brand's catalog
- Capsule is the standard format for this category, supporting precise, consistent dosing
Soy isoflavones are a well-recognized standalone SKU for women's wellness brands and also serve as a common ingredient within larger combination formulas like menopause-support blends. Private label buyers typically specify their target isoflavone percentage and capsule dosage, and should flag soy content clearly for consumers managing soy allergies or sensitivities.
