The micro tablets dissolve almost instantly and have no lingering after taste. I immediately felt the difference a boost in vitamin B-12 had on my system: no more brain fog, no more lethargy, and no more angst. I purchased two bottles: the second one for my mom. She also felt an immediate boost in energy and noticed her mental processing is becoming clearer.
