A unique blend of saw palmetto and other plant extracts to support healthy prostate function in adult men.†
Detail Overview
Saw palmetto is highly useful for support of prostate function in adult men, and so are a number of other plant extracts and nutrients.† Four botanical extracts with recognized roles in prostate health are combined in ProstaThera™ to augment the actions of MultiThera® multivitamin formulas along with key trace elements and lycopene creating a highly beneficial prostate-support program. These ingredients influence testosterone metabolism and promote a favorable balance with dihydrotestosterone, help reduce an age-related decline in prostaglandin production, and help maintain normal cell and tissue functions.† Graminex® flower pollen extract contributes a unique, natural spectrum of amino acids, carotenoids, flavonoids, phytosterols, nucleic acids, minerals, vitamins, and enzymes and has been shown in numerous clinical trials to be particularly beneficial for prostate and urinary function.† ProstaThera™ clinical trial results in clinical improvement in prostate and urinary functions were observed in 92% of men participating in an unpublished, open-label clinical study of ProstaThera™.1 Twenty-four men took 1 tablet twice daily for 12 weeks. American Urological Association Symptom Index (AUASI) scores showed noticeable improvement in the majority of subjects within 6 weeks with no adverse effects.†

Hormone precursor to support mood and memory
Benefits and Features
Pregnenolone is a hormone precursor to over 150 hormones. Restoring pregnenolone to youthful levels may have a positive effect on memory, mood, and energy.†
Detail Overview
Pregnenolone is an endogenous steroid and precursor/metabolic intermediate in the biosynthesis of most of the steroid hormones, including the progestogens, androgens, estrogens, glucocorticoids, and mineralocorticoids. In addition, pregnenolone is biologically active as a neurosteroid.† Pregnenolone levels drop dramatically after age 30. Research indicates that restoration of pregnenolone to the levels of healthy young adults may have a positive effect on memory, mood, and energy.† Physiologically active pregnenolone, derived from natural diosgenin sterols, is micronized to a very small particle size to facilitate absorption.
