Hi Deb!
Does the methyl B-12 (sublingual) negate the malabsorption issues related to gluten intolerance? I've thought I have read it bypasses the intestinal absorption issues (if absorbed sublingually)? Since you know more about your malabsorption issues, thought I'd ask your opinion on this.
I have found my toughest times of functioning to be caused by changes that are truly multifactorial in nature. On a rare occasion, I can trace it down to one factor; yet, this is incredibly rare.
If this continues for you, while taking your B-12, maybe try some d-ribose?
This makes a huge difference for me! I had started this last summer. It gives me so much more muscle strength, energy, stamina. This has really shown up in my ability to use muscles for walking! I enjoy an incredible difference!
(See MrsD's thread on this in her post above. I happen to use Jarrow's D-ribose and love it. I may try another brand soon, just to see if there is a difference in performance.)
Always happy to learn as to how things are going for you!
I hope you feel better soon!
