After having a high serum level of approximately 1900 for years without supplementation, I had a test that determined I wasn’t absorbing it. Exactly what Mrs. D said the first time I posted. I was put on 1000 mcg with folate and B6. It worked great! In fact for two weeks it was the best I’ve felt in years. Unfortunately a couple of weeks ago, it stopped helping and all of the old symptoms came back. Has that happened to anyone here?

I’ve decided on my own to go up to the Jarrow formula 5000 with 800 folate and 2.5 B6. I’m just wondering if anyone has thoughts as to why it would stop working and I’m also curious if most of you take the B12 alone or if you take it with the folate and b6 formula. My folate was also very low, but my b6 was normal.

Thank you!
