I have been taking this product for many years - thanks
Well made hard to find item at a reasonable price. My Hg is always on the low side of normal. I have a slight case of Mediterranean anemia and the number has come up just slightly above normal after using this product with B12.
I'm very pleased with this product. I have tried a few other products by other companies that either didn't work at all or worked some only for a while. I'm healing now and feeling better and I will reorder it soon. I recommend it.
