Selenium is a component of many selenoproteins that play a critical role in reproduction, thyroid hormone metabolism, DNA synthesis, and protection from o...

Steve Bui, M.S.If you look at any advertising in the media, you will notice constant bombardment by ads for performance enhancing supplements. The supplement industry is one of the most lucrative marketing fields. The promise of being able to perform bigger, faster, and stronger by drinking some special water, swallowing a small pill, or anything in between just sounds so appealing. Unfortunately, unbeknownst to the majority of consumers, most supplements do not work at all. Supplements are desi...

Majid Koozehchian, M.S.Vitamin C is a water soluble vitamin, and thus our body does not retain it in large amounts. It is a strong antioxidant that has a key role in protecting against oxidative damage and tissue trauma. Vitamin C can neutralize potentially harmful reactions in the watery parts of our body, such as blood and the fluid inside and surrounding cells. It is one of the vitamins that many athletes consume in rather substantial amounts; therefore they are more familiar with i...

It is formed from methionine, a proteinogenic amino acid, and can biosynthesize back to methionine or into cysteine, another proteinogenic amino acid, as well as several other substances. Benefits of Hcy are unknown; however, its harmful effects...

Chang Woock Lee, B.A.Cholesterol is perhaps the most notorious biological molecule of all. To many people, cholesterol is simply a synonym for heart attack, stroke, or cardiovascular disease because excessive blood cholesterol and lipid contributes to development of plaque build-up in the arteries and can eventually narrow and clog the blood vessels. Thus, cholesterol has become a nemesis to be overcome and destroyed. People try to eliminate cholesterol from their diet, and the media constantly ...

Emily Schmitt, Ph.D.Should I “Enhance” Athletic Performance with Dietary Products?This is one of the questions that constantly arise in the sports medicine and performance world. And to be honest, it is a difficult question to address. Researchers have studied diet manipulation for years in relation to delaying the onset of fatigue, and these studies have resulted in mixed conclusions. Scientific publications conclude that carbohydrate (products such as energy gels or ...
