The flip-top container comes with 60 fast-melting tablets. The bottle and tablets have a distinct odor, not necessarily a bad one, but it's pungent and your finger tips will smell after handling. They do dissolve quickly for those that have trouble swallowing pills. They do have a hint of strawberry taste but I was not able to get past the odor. These tabs are sugar-free, gluten-free, not genetically modified and vegan, which I really like. I am not a physician but this synthetic type of B complex is supposedly good for those with anemia (iron deficiency) and diabetes. The list of ingredients in this B-complex are 150% of the daily recommendation with the exception of Biotin at 1500% and B12 at 15,000%. I experienced no upset stomach when taking on an empty stomach. I also did not experience any boost of energy like I get from my current B-complex. I am not sure if this type of synthetic B-complex is designed for specific or particular health conditions that I do not suffer from so I am not sure what health benefits this supplement is supposed to provide. This product did not “wow” me and I am not planning on deviating from my current B-complex.
