Sorry about the repetitive nature of this post, but it was noticeable for me how much improvement I felt in my energy levels when I started to take a B50 tablet and a B12 tablet (methyl type) regularly. Few of my vitamins have brought me this much noticeable difference. These are two tablets I make sure to never forget to take. I strongly believe in the power of the B vitamins and recommend them to everyone. Many of my friends are taking them now...including a friend in the medical field who took the time to do her own research and is now a big fan!
