Be very, very careful with this mega-dose of B12. Humans only need a tiny amount of B12 - 2-3 micro grams per day. These 5000 mcg tabs will blow you out of the water. That's exactly what happened to me. Firstly, it was awesome - after being slow, generally in the bad mood and not motivated to do anything in daily life (due to b12 insufficiency caused by veg diet) I started taking them and voila - I was almost immediately back into action! Heaps of energy! "Can do anything" attitude! But little I knew. After a couple of weeks on these I started getting headaches. Like really bad ones, lasting for, I kid you not, 2-3 days in a row. Imaging waking up with a headache. Going to work. Then going back home. Falling asleep. Only to wake up with that headache again. So, be very, very careful. I'd say get a mildel version of these. And if you get headaches - STOP TAKING THEM!
Did the formula change?

I was taking this daily with great results and would have given it 5 stars. Then I noticed feeling worse after starting on a new batch. I am on a forum of people who take this for various health issues and there is a whole thread about people who had been taking Jarrow Methyl B12 who noticed less effectiveness. Not sure what changed, but clearly, something has. Will be buying a different brand for now, but for most other supplements, I love Jarrow.
Do not by this>>>Buy Solgar's

I did not remember I was taking this until I looked up my order history. It means to me that this B12 did nothing, no noticeable effect. However, Solgar's B12 is a miracle!! Please take a look at my review on Solgar's B12!!

It's too soon to tell. I was told I wouldn't feel a lot better until the third month. This goes for my entire order.
