This B-12 vitamin complex comes in a liquid form, which I find easier to digest. My bottle has a dropper, which makes dosage easy to measure and ingest. As for the product....I was always exhausted by mid-afternoon, especially on days that I worked out. I have noticed an NOTICABLE difference in my energy levels throughout the day in this past month of use (I began to feel this about 1-2 weeks of consistent use). My only negative comment on this is the horrible taste and smell (I do not know how to describe it....it has that pungant odor that many natural supplements have).
