> 3 dayThis is my go to. It was recommended to me by my neurologist and I’ve seen a big difference since I started taking it 2yrs ago. I have the MTHFR gene mutation and some other health problems that make it where it’s difficult to not be deficient in B12. Jarrow has been a reliable brand who doesn’t cost an arm and a leg. The taste is decent, it’s easy to chew, and does the job.

> 3 day1000 mg made me jittery after a few days. I cut it d own to once every 3 days and now I can tolerate it. I can tell you this works and it works WELL. My MD told me to only buy Jarrow Methyl B-12, I dont know why. But it works very fast and will zing you out, so watch for it and reduce dose if needed.

> 3 dayI take this B-12 supplement a few times a week. I am a semi vegetarian and was told to supplement with B-12. I do feel an energy boost from it but not a jitter kind of energy, more like a I wanna go do something kind of energy. My husband also takes this and has said the same thing. A gentle energy boost. No negative side effects at all from either of us. We are both productive during the day and we both sleep great at night. If this review has helped you at all please let me know. Thanks!

> 3 dayMy husband takes these everyday with a few other vitamins. We chose this particular brand because of the type of B12 listed in the ingredients and the various levels of B12 we could order and choose from as our needs may vary. It works for my husband very well and he says he can feel the difference if he does not take one. He chews it normally to take it. I have tried taking them and do not feel a noticeable difference, even when I take it daily with consistency. We will continue to order it since it makes a difference for my husband and is a good price.

06-06-2025I have much I could say about Jarrow Methyl B 12. I have had Rheumatoid Arthritis for 45 of my 50 years, Recently I was diagnosed with severe anemia and B 12 deficiency. My symptoms ranged from horrible nightly Neuralgia pain, balance problems, speech problems, anxiety. After just 3 months taking 9,000 mcgs a day the Neuralgia pain is gone, my balance is so much better as is my speech. America needs to learn the difference between the main types if B 12 - Methyl the right kind and Cyanocobalum the wrong kind which is what is sold the most. I experienced a distinct difference as I took both. I will always choose Methyl B 12 in the future.

> 3 dayThis is the best B12 Ive encountered. Im in the health profession and usually give it to patients via injection. However, I also know that the alternative route for best absorption is sublingual. I tried another brand in the past that did not work so I stopped taking B12 altogether. However, I had fasciculations...almost like a nerve twitch - for lack of a better explanation, that had been going on and started to get progressively worse last year to the point that I started having PVCs. . I actually put myself on the monitor and panicked when I saw it. Im too young for this and I have no cardiac history. It was in my legs years prior but it started coming up and was getting allover- torso, face, back...scary. I mean it was so bad I started to worry about ALS but I dont have it in my family or fit certain risk factors. Plus, I had low energy and other symptoms. B12 deficiency is no joke as it can cause B12 anemia and other nerve issues. Then first thing to go when I started taking this was the PVCs, then the upper body fasciculations. I guess last in , first out. Eventually, the frequency for the lower body ones decreased and has gone away. I stopped taking this initially last October when everything went away and eventually after about 6 weeks, i started noticing the twitch in my legs so I went back on it. I have it on subscribe and save. I dont take it on a daily basis now. Initially I was. Ill say I take it on an almost daily basis. The weird thing is that for me it, makes me sleepy so I only take at night. I And yes, the other B12 related symptoms resolved. Im hoping this review helps someone because B12 isnt a usual suspect for a lot of things and it can be crazy and a bit scary.

> 3 dayI love this brand because it is METHYLCOBALAMIN and not CYANOCOBALAMIN which is in most Vitamin B-12 products. Cyanocobalamin is a synthetic form of vitamin B12 found only in supplements, while methylcobalamin is a naturally occurring form that you can get through either food sources or supplements. I like these in particular because they are chewable and I usually chew one in the morning and then later on in the day for a pick me up and they truly DO give a great boost of energy!! I highly recommend Jarrow

12-06-2025I got my blood tested and my B12 is high... it used to be really low. I am not sure my body (Ihave MTHFR issues) absorbs B vitamins well but this is absolutely helping me. I highly recommend them.
