Waited for a very long time before this product was brought online by I-herb. Have been researching a large number of similar products, and came to the conclusion that this one is by far the most superior, in terms of its components. It is the only multi that I know of that has balanced (whole) vitamin E with all E vitamers present. Decent amounts of D, and superior forms of B vitamins. This product particularly has the methylated form of B12 as opposed to cyanocobalamin form, which has cyanide, which is universal to other multis. The ingredients in this multi are not without flows however, it contains too little zinc (11 mg I think), which is low for a sexually active male or a person in stressful conditions (usually would need more zinc), also if the person is low in zinc to begin with. Maybe also more Folate than a person would usually need. Finally, it also could benefit from more B5, more Magnesium, and more C (it is particularly low on Vitamin C). My final saying on this multi is that you feel the effect immediately (two or three days after you start taking it). It feels like night and day. This multi serves as a basic pillar for any supplements program for any purpose. This is the best Multi-vitamin by far, but some tweaks in its composition would make it better still. Four star is adequate in my opinion.
