BioMatrix progesterone is derived from an extraction of the steroidal backbone of the Mexican Wild Yam (Dioscorea villosa). It is bioidentical, which means it possesses the same molecular structure as that produced naturally by the body.
Vitamin E (mixed with tocopherols) is a blend of natural-source alpha-tocopherol and mixed tocopherols. An independent assay of a leading brand of oil-based hormones determined that only one form of vitamin E (tocopheryl acetate) is included in their formula. Acetate is cheap acid, used in wood glue. In contrast, BioMatrix uses premium vitamin E in mixed tocopherol forms for enhanced stability and oxidative protection.
Rice Bran Oil is a reliable oil carrier that contributes to the stability and viscosity of numerous formulas.
