Sleep is one of the most important (and easiest) ways to stay healthy.  If you have trouble sleeping but don't like having to take a prescription or OTC drug, check out a melatonin supplement, like SomnaPure (my favorite)

If you're working out and eating properly, you're probably in good health.  There's always more you can do to keep your body in healthy shape though; Men's Health recently published an article titled "The 5 Supplements Your Heart Needs," by Amanda Junker, which covered nutritional supplements not usually associated with body building, but are key components to cardio health.  The important part of the article are posted below (source).  For those of you using or thinking of using Force Factor, they also make a multivitamin and omega-3 product along with their NO supplement.

Aspirin Aspirin is an anti-inflammatory medicine that thins your blood, making it more difficult for your body to develop clots that can cause heart attacks. A Canadian study shows aspirin is especially effective in men. The reason why isn't confirmed, but researchers speculate it's because "blood clots tend to form in bigger blood vessels in men, and aspirin could have bigger efficacy in these larger cells more readily," says Don Sin, M.D., of University of British Columbia, one of the study's researchers.

Omega-3 This fatty acid is found in fish, and it can be helpful in balancing blood lipids such as cholesterol and triglycerides. "Fish oil is helpful for people who have high triglycerides or who are at risk of heart disease," says Charles Campbell, M.D., clinical cardiologist and director of inpatient services at the University of Kentucky. Studies show Omega-3 can help prevent heart attack because it slows the build-up of plaque in the arteries. You can get pure fish oil in capsule form, but that can be expensive, and eating more fish will do more to improve your total health. "The best way to treat triglycerides is to treat metabolic syndrome with diet and exercise—prevention starts there," he says.

Vitamin D D can determine your risk of heart attack, according to a recent Framington Heart Study. "Vitamin D deficiency is associated with increased cardiovascular risk, above and beyond established cardiovascular risk factors," said Thomas J. Wang, M.D., assistant professor of medicine at Harvard Medical School in Boston, Mass. The higher risk was particularly evident among individuals with high blood pressure.

Coenzyme Q 10 "CoQ10 has shown to increase heart contractility [the performance of cardiac muscles]," says Dr. Campbell. A bonus: It may improve muscle function throughout your whole body. Preliminary research suggests that CoQ10 causes small decreases in blood pressure (systolic and possibly diastolic), according to the Mayo Clinic. Low blood levels of CoQ10 have been found in people with hypertension, although it is not clear if CoQ10 "deficiency" is a cause of high blood pressure.

Niacin "More men die from low good cholesterol than high bad cholesterol—and niacin boosts that HDL ‘good cholesterol,'" says Dr. Berkowitz. "HDL is a clearing mechanism to get rid of LDL or bad cholesterol, it's like the garbage truck of the system," says Berkowitz. "Boosting HDL facilitates the transport of cholesterol and triglycerides so they can be extracted out of body." The downside: It must be taken at very high doses to be effective, so side effects like flushing and diarrhea are common. Use this like a drug with a doctor's recommendation.
