Lutein and Visual Processing

Lutein and zeaxanthin are known to help certain people who suffer from macular degeneration, an eye disease. A new study suggests that they may also improve visual processing, perhaps through effects outside the eye. For more details of the study, including dosage, as well as our tests of supplements, see the Review of Vision Supplements with Lutein and Zeaxanthin Review >>

New Curcumin Increases Bioavailability

Curcumin (from turmeric) is not well absorbed, so many formulations have been developed to increase its bioavailability. A recent study found a new formulation to be 49 times as bioavailable as standard curcumin, making it, by far, the most available form on the market. Get the details about this and other formulations of curcumin, as well as CL's tests and reviews of turmeric and curcumin products, in the Turmeric and Curcumin Supplements Review >>

Take Choline When Pregnant

It was recommended last year that women take a choline supplement when pregnant. Adding momentum to this recommendation is a recent study showing that giving pregnant women a larger amount of choline than normally considered adequate resulted in improved information processing speeds in their infants. Currently, choline is not found in most prenatal vitamins. For more information, see the During Pregnancy and Lactation section of the Choline Supplements Review. (Also see our Top Picks among products.)

Saw Palmetto May Not Work

It's used by many men hoping to reduce urinary symptoms caused by benign growth of the prostate, or BPH, but a new, well-designed study suggests that it doesn't work. Some other recent research suggest the same. Even when doubling and tripling the standard dose, the high-quality saw palmetto extract used in the new study failed to provide benefit.

What should you do? You may want to consider a different supplement -- beta-sitosterol, a phytosterol. The evidence remains fairly good for beta-sitosterol. To find out more about saw palmetto, beta-sitosterol, and the supplements we have tested, see the Prostate Supplements ReviewMore >>
