Very nice B-Complex supplement, there is a lot going on with this supplement, it contains five b-vitamins that use the active methylated form of the vitamins, a nootropics blend and more 11 vitamins total, the serving size is just two capsules daily, the capsules are soft and were easy to swallow, so far this supplement agrees with me perfectly with no side effects, as with any supplement it's difficult to know the effects with short term use.I like that this supplement is made in a GMP facility and is NSF certified, non-gmo and 3rd party tested for heavy metals, microbes and for potency it also doesn't use proprietary blends so you know exactly how much of each ingredient is in the serving.Overall I highly recommend, excellent top quality ingredients, made in the USA, contains 30-servings.
