I am sure this is a fine multivitamin for most men, however I am someone who has always been very sensitive to multivitamins. I took this after eating a full breakfast. I was fine for a couple of hours after taking it, then suddenly got extremely nauseous and felt like I was going to vomit. Fortunately for me it did not last long. I drank a bunch of water to help clear my system. There is far too high amount of B-vitamins in this. It made me feel a little weird, and like I had ingested a large amount of caffeine. Not natural energy. I don't know what percentage of B vitamins gets absorbed, but any product with 1200% daily value of B-6, for example, is way way too much for any person at one time. I believe they have a formula with much less amounts of B vitamins that I might be interested in trying. I do like the fact that there is food based nutrition and the packaging is completely recyclable (the label comes off very easily and allows the bottle to be recycled).
