Product Description
Kudzu root extract (Pueraria lobata) is standardized to puerarin, commonly 15%, 30%, 80% or 98%, or to about 40% isoflavones.
Puerarin is an isoflavone glycoside used in capsules and in some alcohol-metabolism research formulas. The 40% isoflavone grade is a broader cut and will not meet a 98% puerarin test.
When buying, choose puerarin or total isoflavones and write the percent. Confirm the species; other Pueraria roots are sold.

Applications
Drink Concepts
Puerarin solubility is modest. Trial the grade before a clear beverage.
Root Extract Versus Starch
Kudzu starch is a thickener. This powder is the isoflavone extract.
Tablets
15% and 98% puerarin do not share a tablet weight.
Isoflavone Blends
The 40% isoflavone grade is the blend grade. It will fail a 98% puerarin test.
Not Kudzu Starch
Starch thickens a food. This extract is the puerarin or isoflavone fraction.
