Product Description
Ever feel like you'd have to eat a whole field of soybeans to get the good stuff? We did the hard work for you. We took the superstar plant compounds from non-GMO Soy Isoflavones Powder-think of Genistein as the lead singer-and squeezed them into a pure, powerful powder. It's like soy, minus the boring bits.
Your body loves it, it helps keep things in balance (a win for women's wellness!), and we test it so much it's practically exhausted. Ready to make supplements that don't sound like a science textbook? Start here.


Types of Soy Isoflavones Powder Available
We offer various standardized concentrations and ratios to suit diverse formulation needs:
Standard Soy Isoflavones 40%
Contains ≥ 40% Total Isoflavones, predominantly as glycosides (Daidzin, Genistin). A cost-effective option for general wellness formulations.
01
High-Purity Soy Isoflavones (80% - 98%)
Ultra-purified extract with very high total isoflavone content, ideal for high-potency supplement applications where low dosage is key.
02
Aglycone-Rich Soy Isoflavones
Standardized for high levels of the active aglycone forms (Genistein, Daidzein), which are readily absorbed by the body without requiring gut bacteria conversion.
03
Customized Ratios
Tailored blends with specific ratios of Daidzein to Genistein, or standardized to a single predominant isoflavone as required.

FAQ
Q: Is this safe for women with estrogen-sensitive health histories?
A: Our Soy Isoflavones Powder act more like gentle plant messengers than human estrogen. Still, if you're managing a specific health condition, it's smart to check with your doctor first-better safe than sorry!
Q: What's the deal with glycosides vs. aglycones?
A: In nature, soy's good stuff comes "locked" with a sugar (glycoside). Your body has to "unlock" it to use it (aglycone form). Our extract delivers the unlocked version, so it gets to work faster-especially handy if digestion isn't your strong suit.
Q: Can guys take this, too?
A: Absolutely! At regular supplement levels, soy isoflavones are safe for men and won't mess with testosterone. In fact, they're often studied for heart and prostate support.
Q: Can I try a sample?
A: Sure thing! We offer free 25–50g samples of our standard products (like our 40% grade) to qualified businesses. Custom blends might come with a small production charge-let's chat details!
