Progressive Lab B-12 with Intrinsic Factor

I have been using this product for about 15 years. My body isn't able to sufficiently absorb nutrients from food. Since taking this, when I eat (my restricted diet due to allergies), I have energy. I also take regular B-12 pills but no longer have to give myself B-12 shots. I definitely recommend this product.

Good Product

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.

Very good product

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.
