As a new school year approaches, many parents are hoping for a breakthrough for their children: Higher grades, better behavior and fewer talks with exasperated teachers. Tutors, counseling, stern lectures and good old-fashioned wishful thinking are all possibilities. But some moms and dads also try to give their kids a nutritional edge in the classroom with the help of supplements. Many supplements promise to boost young brains with doses of docosahexaenoic acid, or DHA, an omega-3 fatty acid that's naturally found in cell membranes throughout the body.

Struggling with the black dog of depression? The supplement aisle abounds with options for people seeking a non-medicinal remedy - but figuring out what works and what doesn't can be a challenge for consumers and experts alike. That's because the data are generally poor, says Dr. Charles Raison, associate professor of psychiatry in the College of Medicine at the University of Arizona in Tucson. There are some exceptions. Hundreds of studies have investigated the effects of omega-3 fatty acids and St. John's wort.

Not so long ago "working on a tan" meant a choice among baking in the sun, broiling on a tanning bed or slathering on a chemical-laden self-tanner that left streaks, smelled awful and imbued skin with a distinct fake orange glow. Today, there's another choice. All-natural and organic ingredients have arrived inself-tanningformulations that rely on sugar beets and various natural oils to help gradually darken the outer layer of skin. These eco-friendly products are free of many of the no-no components other all-natural skin care products avoid, such as parabens, synthetics, fragrance, colorings and dyes.

A glowing suntan is still glorified in the U.S., despite decades of public education campaigns about the relationship between sun exposure and skin cancer. According to the American Cancer Society, rates of melanoma, the most lethal form of skin cancer, have continued to increase through the last 30 years. And though death rates from melanoma have recently decreased, largely due to earlier diagnoses, almost every hour one American dies of the disease. In light of these statistics, it's no wonder that sunless tanning options — creams, aerosol sprays and pills — continue to flood the market, promising consumers who seek darker skin tones a golden glow without the harmful effects of UV radiation.

An omega-3 fatty acid plentiful in fish oil boosts the ability of healthy young adults, whose brains are already at their peak levels of speed and performance, to hold several items in memory for a short time, a study has found. The study is the first to suggest that fish oil might enhance cognitive performance in healthy people by boosting their working memory. The latest research adds to evidence of fish oil's beneficial neuropsychiatric effects: Supplementation with the docosahexaenoic acid (DHA)

Claims touting a component of fish oil as a mood enhancer and a spur to infant brain development may be a bit fishy, a new study suggests. DHA, an increasingly common ingredient in prenatal vitamins and baby formula and taken as a supplement by pregnant women, failed to prevent postpartum depression or to enhance babies' cognitive development or language acquisition, a large study has shown. The finding, reported Tuesday in the Journal of the American Medical Assn., casts new doubt on a dietary supplement whose promise as brain food has been aggressively marketed despite inconsistent results.
