I finally found a B-12 supplement that works perfectly, I am not allergic to the fillers/flavors, and has no side effects (which only took me about 3 yrs!) but now when I want to re-order it, it is out of stock! It is made by "Seeking Health" and is Hydroxo B-12 (1000 mcg) and Folinic Acid (800 mcg) in a lozenge form. The one I had contained 60 lozenges per bottle (but this part does not matter to me). I take it every day and still have quite a few left but was planning ahead. It is "out of stock" on the Seeking Health website and the only bottle left on Amazon is $105 which is insane and I am not paying! Does anyone know when this product will become available again or where I can buy it? (I don't tolerate the Methyl versions of B-12 or Folate and this product was perfect and like every product that is perfect, it becomes discontinued or out of stock shortly after I find it ). Thanks in advance to anyone who has any info on how to find this product!
