Lena,
I am homozygous 1298C and also have some other snps which have been shown to interfere with B12 metabolism. When I did the Spectracell test, the only nutrient I was deficient in was B12, in addition to low overall antioxidation function. I do not have CFS and have not experienced the symptoms prototypical of B12 deficiency. That is why I need to rely on testing rather than symptom improvement. My symptoms have been low energy and low motivation. I'm feeling better since I started on the b12 oils, but a change in other, totally unrelated, factors could be responsible for that, so I'm reluctant to say it's because of the B12oils.
I started using the B12oils in March 2013, when it was just adenoB12, 3 months before it was commercially available. Back then Greg included Vitamin D3 in the formulation, for a dose of 2,000 IU (IIRC) per pump. He has since removed it from the adenoB12/methylB12 formulation, but upon my request he has added it back in for the pumps I order. To minimize shipping expense per pump, I order 6 pumps at a time, which is the max he can ship without getting into customs declarations. The B12oil has a long shelf life.
Greg switched to a bigger pump awhile back (1-2 years ago?), and each pump now lasts at least 45 days. Someone earlier on this thread talked about unscrewing the cap and using a dropper to get a smaller dose of the oil than one pump would put out. After reading what Freddd has written about how methylB12 converts to hydroxyB12 with very minimal light exposure, this doesn't seem to me to be a good practice.
I have consulted with Greg on my Organic Acid (OAT) tests. He thinks OAT tests are good, often picking up on dysregulations that the usual lab tests don't pick up. If you aren't feeling right, it can be a blessing to finally have a lab result that identifies that something is wrong. Since you have now ordered from B12oils, if you were inclined to get your own OAT test, I think Greg would help interpret it for you.
Vitamin B2 is a cofactor for Vitamin B12 metabolism, so make sure you have enough Vitamin B2 on board.[/
Thank you Lynn, I am on B2 waiting for B12 oils to arrive.
