This is the best Men's multi vitamin I have found. Two days after I run out, even if using another men's multivitamin, I have a very noticeable drop off in energy and overall feeling of wellness. I highly recommend.!

I have bought GNC multivitamins for myself and my family for years. I am so pleased to be able to purchase them from Sam’s Club at a much better price. Please keep stocking them!

I have only been taking them for a week but I have noticed an increase in energy especially around 2pm when I’m normally reaching for a cup of coffee. Take them with meals when I tried it without eating it didn’t sit on my stomach so well.

I have been taking this for about a week now and feel like it gives me more energy to make it through the day. Haven't seen any weight loss, but I will continue to monitor as I keep taking the product.

While I have only used the product about 2 weeks, I have noticed a little energy pickup. I look forward to seeing if that continues to last after taking for a few months. I don't usually take products such as this but I must say "So far and so Good!

This product didn’t really so much for my energy level…Metabolism did not change, but it did curb my hunger…I was expecting an energy boost similar to a preworkout drink, but not as strong…didn’t see any of that at all…

Great daily vitamin and supplemental nutrition developed for active and inactive people. I was buying 1 box in the 1990s for $14. This is a great deal and lasts for months.

Great product!

Two weeks ago I replaced the One A Day vitamin that I had been taking for quite a while with the GNC - GNC Mega Men Energy & Metabolism Multivitamins, 180 count. I haven't noticed any loss of energy or metabolism in my daily routine. I have noticed that in the late evening I haven't nodded off in my chair like I had been.

First the pros: I can tell it does give me a boost when I'm sluggish. It also gives my urine a bright neon green color, which makes for a super cool effect when the bathroom light is off. Now the cons: These things smell, and taste, absolutely horrific. I've been a paramedic for 21 years, and this smells worse than anything I ever encountered at work, and that's saying something. The burping later on in the day is pretty disgusting too.
