5 Popular Anti-aging Supplements

Coenzyme Q10

Also known as CoQ10, this enzyme is an important part of our metabolism. Mitochondria, the power centers of cells, control cell growth and play a role in the aging process. CoQ10 needs to be present for mitochondria to function properly, and as we age, we produce less. Taking CoQ10 in supplement form may keep our bodies healthier and happier and, according to some studies, may boost heart health. Another option, the amino acid acetyl-L-carnitine, may help your mitochondria function properly and can be taken as a supplement. Unfortunately, this enzyme can cause some unpleasant side effects including dizziness, fainting, allergic reactions, nausea, diarrhea and gastrointestinal conditions [source: Monson & Schoenstadt]
