with many people here having issues with 'low acid' and in Deb's post that she was deficient in Glutathioine - it was a hint at the root cause of the issues...
it reiterates the importance of amino acids and their linkage into the methylation cycle
taking this a step further..... this links provides a good explanation of the steps/process. Within it i found the quoted text below, it is another element to people having 'high B12' in blood tests but still feeling poorly...

One of the jobs that glutathione normally does is to protect your supply of vitamin B12 from reacting with toxins. If left unprotected, vitamin B12 is very reactive chemically. If it reacts with toxins, it can’t be used for its important jobs in your body. A routine blood test for vitamin B12 will not reveal this problem. In fact, many people with CFS appear to have elevated levels of B12 in their blood, while their bodies are not able to use it properly. The best test to reveal this is a urine organic acids test that includes methylmalonic acid. It will be high if the B12 is being sidetracked, and this is commonly seen in people with CFS.
When your glutathione level goes too low, your B12 becomes naked and vulnerable, and is hijacked by toxins. Also, the levels of toxins rise in the body when there isn’t enough glutathione to take them out, so there are two unfortunate things that work together to sabotage your B12 when glutathione goes too low
