Multivitamins for Men

By: Kelly Burgess on February 27, 2018

GNC Mega makes a quality line of men's multivitamins

Multivitamins for men don't usually contain iron, because men generally don't need more than 8 mg (milligrams) of iron a day, which is easy to get from diet alone. Premenopausal women need more iron because they lose it monthly during menstruation, so women should see our discussions on Multivitamins for Women or Prenatal Multivitamins elsewhere in this report. Once men reach age 50, they may need more B vitamins, so if you're over age 50, see our discussion of Multivitamins for Adults over 50.

The GNC Mega Men line of multivitamins are well-reviewed across the product line for accuracy in labeling and claimed ingredients, but GNC Mega Men (Est. $30 for 180 capsules) multivitamin rises to the top on the strength of professional tests, expert recommendations and user reviews. It contains no iron, as men in this age group don't need to supplement for that mineral, experts say. Users like that it has higher levels of vitamin D than many other men's supplements -- 1,600 IU.

GNC Mega Men is a pretty standard formulation for a basic, everyday vitamin meant just to cover your nutritional bases, and not for any targeted need. It has a few more B vitamins than you really need, including 50 mg of niacin, which is 250 percent of the current RDA. This leads to the observation that we see frequently in reviews of this multivitamin, that it turns urine a bright yellow color. This is just the body's way of ridding itself of unused nutrients. However, niacin can also cause flushing in some sensitive people. Niacin is often added to supplements as it is thought to act as a thermogenic, or fat burner, often euphemistically referred to as "energy boosting." The combination of included antioxidants claim to support heart, colon and prostate health -- claims that have not been verified by the FDA. It also contains fish ingredients, so it's not suitable for vegetarians or vegans.

If you want a men's multivitamin that specifically targets weight loss, GNC Mega Men Energy & Metabolism (Est. $40 for 180 caplets) is intended to act as a thermogenic fat burner. It contains caffeine and green tea extract in addition to 50 mg of niacin. However, be warned that all three of those ingredients, especially when combined, can cause jitteriness or heart palpitations in sensitive individuals. Do not take this or any supplement if you have any health issues that may contraindicate caffeine.

One-A-Day, Men's Health Formula (Est. $15 for 250 tablets) is another men's multivitamin without iron. It doesn't provide 100 percent of all nutrients -- including vitamin E, vitamin K, biotin, calcium and magnesium, but does contain 700 IU of vitamin D. It gets very high ratings from users, some of whom say they have been taking it for years and find it to be very well-tolerated. Many who have generally healthy diets say they take it just as an insurance policy -- and most love that they only have to take one pill a day since so many other vitamins require multiple doses. One-A-Day Men's Health Formula contains gelatin derived from animal sources, so it isn't suitable for vegetarians or vegans.

Natural vitamins contain no artificial colors, sweeteners or dyes, but they're typically more expensive than other multivitamins. One that does well in testing for ingredient accuracy, product purity, safety and nutritional value is Rainbow Light Men's One Multivitamin (Est. $40 for 150 tablets), which claims to be the "number one selling natural men's multivitamin." However, it contains more than the DV for several nutrients, including 1,667 percent of the DV of vitamin B1, 1,471 percent of the DV of vitamin B2 and 1,250 percent of the DV of vitamin B6. Because cereals and breads are fortified with B vitamins, experts say there's no reason to take more than the DV in a multivitamin, although higher levels of B vitamins within reason won't hurt you and may be a good choice if your way of eating does not allow or include breads, cereals or grains. Like most men's multivitamins, Rainbow Light contains small amounts of calcium and magnesium. This Rainbow Light formula is suitable for vegetarians and vegans.
