According to the product label, the supplement supports energy metabolism, heart and prostate health.

B Vitamins

B-complex vitamins, which include thiamin, riboflavin, vitamin B6, vitamin B12, niacin, pantothenic acid, biotin and folic acid, keep the various organ systems working properly. The body also needs B-vitamins to absorb and metabolize other micronutrients, proteins and fats. A serving of OneSource Ultimate Men's Multivitamins contains 100 percent of your daily needs for folic acid, more than 2000 percent of thiamin, riboflavin and vitamin B6, more than 500 percent of pantothenic acid and vitamin B12, and 250 percent of niacin.

Minerals and Other Nutrients

Each serving of OneSource Ultimate Men's Multivitamins contains 100 percent or more of the daily value for several dietary minerals, including copper, manganese, chromium, molybdenum, iodine and zinc. Selenium is at 286 percent, calcium is at 20 percent and magnesium is at 25 percent of your daily needs. OneSource Ultimate Men's Multivitamins also contains a variety of amino acids and antioxidant blends from fruits and vegetables, along with boron, lycopene, inositol and lutein.


Multivitamins may help fill some of the nutrients missing from your diet, however, there is not enough evidence supporting the need to use supplements to protect or reduce the risk against prostate cancer or heart disease. The National Cancer Institute notes that taking 400 mcg of folic acid may lower the risk of prostate cancer, but taking 1 mg may increase the risk. Neither vitamin C, E, selenium nor lycopene lowers the risk of prostate cancer, according to the Institute. Further, there is not enough evidence to support that vitamins A and E will protect against heart disease, according to the Cleveland Clinic. On the contrary, taking large amounts of a certain nutrients through supplements for long periods can put you at risk of adverse effects from overdose.
