Mice with severe combined immunodeficiency drank brewed green tea, ate a diet with 0.4% quercetin, or both for two weeks. Rutgers researchers report the combination raised total and non-methylated EGCG two- to threefold in lung and kidney. Quercetin inhibits the methylation that blunts catechins.

Green tea extract fights cancer, but this supplement makes it more effective
In mice, brewed green tea plus a diet with 0.4% quercetin raised total and non-methylated EGCG two- to threefold in lung and kidney. Quercetin also quadrupled EGCG uptake in lung cancer cells and cut the methylation that would otherwise deactivate the tea's anticancer compounds.

This ingredient found in meat helps Alzheimer's disease
Rats given homocystine to mimic Alzheimer's changes had less tau hyperphosphorylation and beta-amyloid accumulation and fewer memory deficits when fed acetyl-L-carnitine, a Rejuvenation Research study reports. The researchers call it a promising protective agent.

These supplements fight prostate cancer
In mice carrying human prostate tumors, combining a soy diet with calcitriol inhibited tumor growth more than either alone but also caused hypercalcemia and in some cases lethal toxicity, a study in Prostate found. Soy raised the bioavailability of calcitriol.

Maca power good for your sexual health
Maca, a root grown high in the Peruvian Andes, appears to raise sexual desire in men and women without changing male sex hormone levels. A 2001 study of nine men reported better sperm count and motility, and a later 12-week trial found greater desire after eight weeks on 1,500 or 3,000 mg.

Equol is a nonsteroidal estrogen that gut bacteria make from the soy isoflavone daidzein, though only about 30-50% of people carry bacteria that produce it. Of its two mirror-image forms, S-equol preferentially activates estrogen receptor beta. Text cited from Wikipedia.
