It took about three days but I really started to notice the difference. I had way more energy to get through the day. This has all the vitamins I need for the day so I was able to get rid of my other supplements. The pills seem to have the right amount of caffeine to eliminate that after lunch soda pop.

I've been using this for about 3 weeks now and I'm pretty satisfied with the supplements so far. Multivitamins, similar to other supplements, typically take a while to notice longer term benefits but at least I did not notice any down sides based on the few weeks that I've been taking it. I took these in the evening before bed and it was good in the stomach unlike other supplements. Have been feeling good so far and I can see that the vitamin contents on these pills are much higher than any typical multivitamin so overall pretty happy with it so far.

I got Mega Men Energy & Metabolism about a month ago, I wanted to use it as directed for a month before I wrote this. I do feel more energy which is huge because I'm 62 and battling fatigue. so I give the product a thumbs up. The only down side was that the pills were large and a little hard to swallow.

I’m sure some people are upset with my subject line because coffee is like a religion to them but this stuff just works really well. The reason I say this is better than coffee is because it provides consistent, long lasting energy instead of a short burst like other caffeine products. These pills are slow release and help me stay energetic the whole day and even help me stay super alert on long drives. The pills aren’t too big and are easy to swallow. The only down side is they smell kinda funny, but you can’t taste them anyway. I would definitely recommend.

The product is easy to swallow and does not have an overpowering smell like a lot of supplements do. I have used this product for about thirty days and have definitely noticed an increase in my energy levels. My only complaint is that you have to take two pills a day.. I would definitely use the product again.

I've been taking these for 2 weeks now. After using another brand previously, I feel like these are a far superior product. I can tell there is a slight increase in energy levels, while not affecting my sleep. Pleasant enough taste without the "burps" some supplements tend to bring on. Definitely will be my choice on the next purchase.

Feeling more energy - not sure if it is metabolizing faster, but do feel more energized.

Great product!

I did notice a bump in energy when I started on these vitamins. I've been using them for several years now and I'm happy with them.

I have used these vitamins for several years now and I am quite pleased with the energy it provides.
