These vitamin B12 tablets are excellent for helping me control and maintain my B12 level,along with my monthly B12 injections at my lab in the doctor's office. Nature Made is a wonderful and reliable company and the prices are reasonable for me and my family. I have also taken some of their other vitamins and was satisfied with them. It is so important to take vitamins and minerals especially as we grow older and hopefully wiser. I will certainly continue to purchase the Vitamin B12 tablets asit has become a part of my regular daily regimen.
