Product Description
Daidzein is a naturally occurring isoflavone compound primarily extracted from soybean and other leguminous plants. It is supplied as a standardized botanical ingredient for nutraceuticals, functional foods, and dietary supplement formulations requiring consistent isoflavone content and reliable analytical quality control.
Daidzein belongs to the phytoestrogen class of flavonoid compounds and is one of the major soy isoflavones together with genistein and glycitein. Commercial Daidzein ingredients are commonly standardized by purity percentage and verified through HPLC analysis for professional supplement development.
Daidzein is an isoflavone polyphenol naturally found in soybeans, chickpeas, and other leguminous plants. It is classified as a non-steroidal plant compound with a characteristic isoflavone structure consisting of two aromatic rings and oxygen-containing functional groups.
Commercial Daidzein is commonly produced through extraction and purification from soybean-derived materials or through controlled synthesis processes. It is typically supplied as a light yellow to off-white crystalline powder and evaluated for identity, purity, and active compound content.

Daidzein is widely used in soy isoflavone supplements and botanical formulations requiring standardized isoflavone compounds.
Manufacturers incorporate Daidzein into functional nutrition products containing plant-derived flavonoids and soybean-based ingredients.
Daidzein is commonly included in specialized nutrition products formulated around soy isoflavone ingredients and plant-based wellness concepts.
For buyers sourcing Daidzein, the most important evaluation factors are purity level, botanical source, extraction quality, and analytical verification. Since soybean extracts contain multiple isoflavones, manufacturers should consider whether they need isolated Daidzein or a broader soy isoflavone profile.
| Selection Factor | Why It Matters | Typical Buyer Consideration |
|---|---|---|
| Purity Level | Determines concentration of the target isoflavone compound | High-purity grades are commonly selected for standardized supplement products |
| Source Material | Influences labeling, traceability, and ingredient positioning | Confirm soybean-derived or other botanical source requirements |
| Isoflavone Profile | Determines whether the product contains isolated or mixed isoflavones | Choose Daidzein alone or combined isoflavone extracts according to formulation goals |
| Analytical Documentation | Supports quality evaluation and supplier qualification | Review COA, TDS, HPLC reports, and specification documents |
