It took several months for my breast lump to recede into nothingness. I still don't miss it! B complex is a good backstop and gives you the B's other than B2 and B3. My only question is whether you'll get enough B2 and B3, which the Iodine docs emphasized. You can try it to find out. People have different needs. If you decide to try ATP Cofactors later, it can be purchased on both iHerb and Amazon.
