Coenzyme Q10
Naturally produced by the body, coenzyme Q10 improves the muscle cells' ability to translate oxygen in the blood to usable energy. Unfortunately, as we age, the natural production of this compound decreases. Because coenzyme Q10 is not found in any food source or any available multivitamin, the only way for men to regain their youthful vitality is by taking it in supplement form.

Men who take 100-150 mg of this compound daily have reported a significant reduction in fatigue. The results from recent studies also suggest that coenzyme Q10 may help in the fight against cancer, Parkinson's disease and Huntington's disease.

Creatine
Creatine not only boosts muscle mass, but it is also linked with improved memory and intelligence test scores. Studies at the Medical College of Wisconsin found that men taking creatine for two to three months increased their bench press weight by an average of 15 pounds. By adding 5 grams of creatine a day to whey in a protein shake, you can boost your man's muscle and memory. He will remember your anniversary and can carry you over the threshold like he did on your wedding day. What more can a woman ask for?

Chromium

Although chromium is a popular muscle-building supplement, this mineral is most beneficial for the control of diabetes. By improving the body's sensitivity to insulin, chromium makes it easier to keep blood-sugar levels where they belong. Studies have also determined that men who regularly take chromium picolinate, which is the best form of the mineral, have a much easier time controlling their weight.
