Good for a vitamin D boost. GNC makes several formulations under the Mega Men label, including this fairly basic blend. It has a pretty standard combination of vitamins as recommended for men, including no iron, with slightly higher levels of vitamin D3 -- 1,600 IU. It's on the high side for B vitamins, and exceeds the recommend tolerable upper intake level (UL) for niacin, but that's not considered to be a dangerous or even unusual formulation -- although excess niacin can cause flushing, we did not read of any report of flushing in user reviewers. Mega Men puts a focus on antioxidants with a proprietary blend of fruits and vegetables. It has been certified by professional testing organizations for accuracy in labeling. Instructions say to take two capsules per day.
No red flags. If you have any health problems whatsoever, you should speak with your doctor before taking any multivitamin. However, for most people, GNC Mega Men is unlikely to cause any sort of side effects. Other than the high levels of niacin, which, as we mentioned in the previous section can cause flushing in some, Mega Men's ingredients are fairly standard in a general multivitamin and are well-tolerated by most. Because of its high levels of B vitamins, it may cause urine to appear bright or fluorescent yellow an hour or so after ingestion. This is normal and is merely the body's way of ridding itself of unneeded vitamins. It is gluten-free, but not vegetarian as it contains fish oils.

In more than 630 customer reviews, GNC Mega Men earns an overall rating of 4.5 stars out of 5. A number of users say they started taking it after being diagnosed with low levels of vitamin D and that follow up tests have shown a marked improvement. The only complaints we saw were that it "doesn't work" for some (although they don't specify what they expected it to do), and that this supplement turns urine a bright florescent color.
There are just a few reviews of GNC Mega Men multivitamin at GNC's site, although there are quite a few for other formulations of this line. Still, the basic multi earns an overall rating of 4.7 stars out of 5, although users don't say much about it other than it has a powdery, flour smell.
