IP6 may not only suppress the body s production of free radicals and inhibit lipid peroxidation, but may also affect the basic mechanisms regulating cellular growth, effectively extending its applications to both cancer prevention and treatment. Several studies have shown that diets rich in soy products or supplemental isoflavones increase bone density and strength, and reduce calcium excretion in the urine, indicating that soy may be important in the prevention of osteoporosis. This health benefit is largely due to the presence of daidzein. Daidzein is a metabolite of a compound know as ipriflavone, which has been shown to inhibit bone loss. The ability of isoflavones to bind to estrogen receptors is also important for controlling menopausal and premenstrual symptoms.
Soy lecithin is an important dietary source of choline.
Phosphatidylserine and phosphatidylcholine are two types of choline that have been the focus of recent research. Phosphatidylserine is a vital nutrient for brain cell membranes. Several clinical studies indicate that phosphatidylserine improves learning, concentration, mood, and age-related memory loss. Phosphatidylserine has also been shown to improve athletic performance by suppressing the catabolic stress hormone, cortisol. Phosphatidylcholine is a major building block for all cell membranes.
