Great B-Complex Supplement
The Twin Labs Stress B-Complex is the best B-supplement I've found (and I've tried a few). And on Amazon, the price is good. The potency is excellent - another reviewer posted the amounts in this supplement, which is very helpful for comparing. My husband and I both take this and notice a general feeling of well being (B-complexes are great for balancing hormones/mood) and sustained energy throughout our day. We don't need caffeine in the morning! Also, my nails and skin are much improved. I had symptoms of a deficiency (peeling lips, cracked skin on thumbs and fingers) and within a week of taking this supplement I saw a drastic change. I also appreciate the nice boost of Vit. C for energy and immune support.

I Feel Much Better When I Take These!
I am going through perimenopause and one of the symptoms is joint stiffness and pain. If I don't take these then I feel like I'm a hundred years old when I wake up in the morning. When I do take them, then I'm normal again. I know that I don't get enough of the B vitamins in my diet so taking these really help me feel better and they also give you a good dose of vitamin C too. The bottle says to take 2 capsules a day, but I'm good with just one. These are easier to swallow than most B complex pills. The old style ones just about make me choke, but I can tolerate these. You will notice that these pills will make your urine bright yellow because your body isn't able to absorb all of the vitamins.so if you decided to take two a day it's better to space out the dosages rather than taking them at the same time, otherwise your body will expel the extra potency that it can't absorb into your urine.

As expected
It’s a good product but not as good as the liquid version they used to make a few years ago.
