About 7 years ago, I was experiencing odd symptoms such as tingly hands and feet and extreme fatigue. After months of testing, my primary care doctor sent me to a hematologist/oncologist, convinced that I had Leukemia. The first visit was for blood work and I returned the next week, expecting bad news. My diagnosis was not Leukemia, it was a B12 deficiency! It was the most relief I ever felt. I was given a few weekly b12 shots and some horse pills to swallow. My body went back to normal. Last month, I started getting minor symptoms again. I ordered these gummies to try to avoid choking on pills. It's only been a few days but I feel better already. I am not a doctor so this obviously isn't medical advice if you don't feel well. I just wanted to share that these worked for me as a good replacement to hard to swallow pill
