Pregnenolone 50 mg (plant source) is micronized and sustained released. Itis formulated in a lipid matrix to bypass the liver so that the pregnenolone is presented directly to the systemic circulation and it is micronized to a particle size of less than 50 microns for optimal absorption. Soy free – the source material (wild yam) is non-irradiated and non-ethylene-oxide-treated. Replaces product #74811.
