GNC Mega Men Multivitamin

The GNC Mega Men Multivitamin doesn't contain iron -- a plus since the amount men need can easily come from diet -- and includes important nutrients such as vitamin D, folic acid and calcium. It also has vitamin A, 50 percent of which comes from beta-carotene. GNC seems to follow a more-is-better philosophy when it comes to B vitamins: Mega Men contains 3,333 percent DV of thiamin, 2,941 percent DV of riboflavin and 2,500 percent DV of vitamin B6. However, upper tolerable intake levels aren't established for thiamin and riboflavin, and B6 is well below the upper limit. This multivitamin is approved in independent tests, but experts say these large doses aren't necessary because many food products are fortified with B vitamins. If you prefer a multi with smaller amounts of B vitamins, Target Up&Up Men's Daily Multivitamin (*Est. $7.50 for 210 tablets) and Centrum Silver Men 50+ (*Est. $9 for 100 tablets) also pass independent tests and cost much less.

The best feedback on the GNC Mega Men Multivitamin comes from ConsumerLab.com, which tests dozens of multis in its latest review. The organization analyzes each product to ensure it dissolves properly, contains what it states on the label, and isn't contaminated with lead or other toxins. Although most multivitamins don't attract many user reviews, Mega Men gets a good amount of feedback on Drugstore.com and NutritionalTree.com. Comments on the former seem more credible; many of the reviews posted to NutritionalTree.com sound strangely similar.
