If you condensed your most recent meal down to a few pills, would they be tiny dynamos, or the nutritional equivalent of Tic Tacs? If you're like most men, what's on your plate falls somewhere in between—that is, leaving plenty of room for improvement. "If men start to favor certain foods—meat and potatoes, for example—they may develop nutritional blind spots as a result," says Kristie Lancaster, Ph.D., an associate professor of nutrition at New York University.
This can be a problem, because your body needs a basic roster of vitamins and minerals to run properly. If your regular diet comes up short, you may need a multivitamin to reach this nutritional baseline. But to actually boost your health, you need to consider moving beyond a multi by folding in some less common elements. Lycopene, for instance, is a powerful antioxidant found in tomatoes. Red yeast rice, a heart-healthy statin. Bottled boosters such as these can be insurance policies for your nutritional blind spots—and if you have specific health concerns, a form of extended coverage
The right supplements can help your heart, sharpen your immune system, and even improve your sex life. The wrong ones, however, can be ineffective or even harmful. "You run into problems because most men are 'prescribing' these things themselves," says Tod Cooperman, M.D., president of ConsumerLab.com, an independent tester of health and nutritional products. "Don't take supplements with abandon. They should be used carefully, because taking in too much of certain nutrients can cause problems."
We consulted with top doctors, reviewed the latest research, and waded through marketers' claims to bring you 18 of the best supplements for men. Use our guide—along with advice from your own doc, since many supplements can interact with other medications—to fine-tune your strategy.
Problem: Brain drain Solution: ACETYL L-CARNITINE
This amino acid converts fats to energy and boosts antioxidant activity in the body. In supplement form, it may protect gray matter from stress caused by alcohol and aging. And in a 2006 study, people who received 1,000 milligrams (mg) of acetyl L-carnitine a day saw relief from mild chronic depression.

Our pick: Carlson Co-Q10, 100 mg; carlsonlabs.com ($40/90 soft gels)
Natural sources: Meat and fish, eggs, broccoli
Problem: Bone weakness Solution: VITAMIN D
Vitamin D is a hormone that helps your bones absorb calcium. That's a critical benefit, but there's also a steady stream of other compelling reasons to take it, Dr. Cooperman says. For instance, Vitamin D has been linked to reduced levels of depression, reduced risk of colorectal cancer, and less chance of a heart attack.
Dose: 1,000 IU Vitamin D3/day
Our pick: GNC Vitamin D-3 1000; gnc.com ($10/180 tablets)
Natural sources: Sunshine, fortified milk
Problem: Heart disease Solution: FISH OIL
Loaded with the essential omega-3 fatty acids EPA and DHA, fish oil can reduce triglycerides, boost HDL cholesterol, and lower blood pressure. But your heart isn't the only beneficiary: The healthy fats may also reduce inflammation and improve cognitive performance, and may lower your risk of colon and prostate cancers.

Our pick: Nordic Naturals Ultimate Omega; nordicnaturals.com ($28/60 soft gels)
Natural sources: Salmon, tuna, or other fatty fish

A drop in magnesium can be a major headache. "Blood vessels in your brain constrict, and receptors in the feel-good chemical serotonin malfunction," says Alexander Mauskop, M.D., director of the New York Headache Center. Result: a migraine. The mineral also might help regulate blood pressure and could ward off stroke and diabetes.
Dose: 250 mg/day, plus the magnesium in your diet
Our pick: Life Extension Magnesium Citrate, 160 mg; lef.org ($9/100 capsules)
Natural sources: Leafy greens, whole grains, pumpkin seeds, coffee, nuts
Problem: Diabetes Solution: PSYLLIUM HUSK
This fiber is more than a colon clearer. In a recent Finnish study, the addition of psyllium to meals reduced participants' blood sugar and insulin response. Paired with protein, it was also shown to suppress ghrelin, a hormone that makes you hungry. Psyllium is one of five soluble fibers approved by the FDA for lowering LDL cholesterol.

Our pick: GNC Natural Brand Colon Pure; gnc.com ($16/19 oz)

Probiotics are healthy bacteria that crowd out the disease-causing bad bacteria in your gut. Some can reduce diarrhea caused by certain infections, antibiotics, chemotherapy, and irritable bowel syndrome, Dr. Cooperman notes. The encapsulated good guys may also boost your immune function.
Dose: 1 capsule (with at least 1 billion bacteria) a day
Our pick: GNC Natural Brand Acidophilus Probiotic Complex; gnc.com ($14/100 tablets)
Natural sources: Yogurt, kefir, and other dairy products

Our pick: Jarrow Formulas Quercetin 500; vitaminexpress. com ($16/100 capsules)
Natural sources: Red wine, parsley, grapefruit, onions, apples
Problem: Poor memory Solution: PYCNOGENOL
This supplement's antioxidants fight free-radical stress in your brain and stop the degradation of nitric oxide, which preserves neural connections.

Dose: 150 mg/day*
Our pick: TwinLab Pycnogenol, 50 mg; twinlab.com ($50/60 capsules)
Natural source: Pine bark
Your noggin depends on a variety of nutrients to keep itself balanced. Eat these6 foods to increase your brainpower.
Problem: Joint pain Solution: GLUCOSAMINE
Glucosamine, a building block of cartilage, can relieve pain and inflammation in joints, says Nicholas DiNubile, M.D., an orthopedic surgeon.

Sixty percent of adult men don't get enough vitamin C in their diets, according to an American Journal of Clinical Nutrition study.

Our pick: Ester-C, 500 mg; cvs.com ($11/90 tablets)
Natural sources: Rose hips, citrus fruits, broccoli, guava, kiwifruits, parsley
Problem: Extra body fat Solution: EGCG
Men who took green-tea extract burned 17 percent more fat after moderate exercise than those taking placebos, according to one study.
