I don't know why, but this vitamin makes me throw-up every time I take it. About a couple of hours after eating and taking the vitamin, I suddenly feel sick. I won't be taking it anymore. I do like other Country Life vitamins, but this one does not work for me.

I have been using Jarrow Formulas Methyl B-12, 5000 mcg for eight years. Up until now, they have been great. After years of suffering, I finally went to a doctor who knew to check my B12 level, but he didn't understand how to treat it properly. He only prescribed shots temporarily, so I started taking these vitamins to keep my level up. It worked! My level has always stayed above the highest end of the particular lab's testing range (>2000). As of 2017, something has changed about these vitamins. The taste is so horrible that I really thought I had a bad batch. As another reviewer stated, they are chalky, but it's worse than that. We also order the 1000 mcg form for our children, and those do not have the bad taste. I need the 5000 mcg (at least two per day dissolved under the tongue) to keep my B12 level up. I still do not know if I received a bad batch (two bottles of the same expiration date) or if this is a change Jarrow has made. iHerb was kind enough to allow me to send the bottles back, but I chose to keep them because I am pregnant and am unsure if there could be something wrong with these vitamins. If anything were to happen to my baby, we will have these tested. I also contacted Jarrow with my concerns but got no response. If they have made poor changes, I would just like to know. In the meantime, I have been trying other brands of Methylcobalamin but can't seem to find one that I think works well. I feel more numbness everyday. If Jarrow has not made changes and this was a bad batch, I would really like to know so that I can order a good batch. There aren't any doctors in our area who prescribe Methylcobalamin injections, so the only way I can keep my level up is by quality tablets/sublinguals.
