I have used this product for at least 2 years. It gave me energy after working 3 consecutive night shifts. I take them after a meal before I get ready for work. I don't take them before going to bed because I wake up before I really need to wake up. I also take them so I'm not wasted after a vigorous workout.
I have only recently started taking these pills. So far I feel like I have more energy. I think it will take a little longer to see any results on my skin. The only down side is it is a LOT of pills to take at one time. However, my philosophy is "no pain, no gain".
I am nearly done with my second box. I didn't notice an immediate difference, but towards week 3 I noticed a significant improvement to my nails. I received compliments on my skin, but wasn't sure what to attribute to these supplements versus new skin care products and makeup. I have an incredibly sensitive stomach and this is one fo the few that I seem to be able to take without getting heartburn or stomach aches. So I bought a second box. I have a bout a week left int he second box and am about to order my third. It is a lot of money. But considering how hard I have worked to try to find a multi- vitamin that didn't hurt my stomach and the results I see in my nails and hair, I think it is worth it.
