Besides the fact that methylcobalamin injections aren't even available in Canada (not sure about the US but was unable to get them at major pharmacies although they seem to available via certain select laboratories), I brought my serum b12 level from the mid 100's (pg/ml) to high 900's simply by supplementing with sublingual methylcobalamin 1000mcg a day every day... not sure exactly how fast it rose but I had my blood tests done a year apart. I've been a strict vegan for 9.5 years. DR just likes needles.
I haven't seen any evidence of anyone taking 1000-2000mcg sublingual methyl tablets daily for at least 3 months who wasn't able to get their levels up.
I do know some people that have not had success with sublinguals. Good you are doing well with em ilan. :)
Do you know what your homocysteine/uMMA levels were before and after?
Any b12 ampules from a pharmacy will work. Methyl just gets a better rating thats all.
Im a man that enjoys certainty. I want to know my front wheel on my bike is secure. I want to know what Im doing is working. Im OCD objective in that respect. Thats why I do/promote b12 shots vs sublinguals. Even my meat eating friends come to me for b12 shots.
My homocysteine levels were normal even while my serum b12 was deficient (of course I had to tell my physician my b12 lvls were low since they fell into the bs lab range). I did not have a uMMA test done. The blood test I just had recently came back perfect in every regard we did a CBC, lipid profile, b12, ferratin, etc.. as well as urinalysis.. all spot on.
The only individuals I know who haven't had success with sublinguals are those who were on cyanocobalamin which is entirely ineffective... like taking a placebo. It's not a big deal but obviously it is a lot more convenient to just stick a tiny pill under your tongue for 2 minutes a day than to inject yourself... especially when traveling. Here in Canada you need a prescription for b12 ampules and the dosage costs 2x as much as taking sublingual tablets.
I would like to see evidence of individuals supplementing consistently with sublingual methyl who weren't able to absorb it. Maybe we'll have some volunteers on this board.
Didn't work for me. I used nutrisorb b12 for a year. Levels were actually lower at the next test.
Nutrisorb is not sublingual methylcobalamin, the brand seems a bit fishy, and one serving is only 50 mcg. It doesn't surprise me that your levels didn't rise.
took that amount for 1 year and my levels still went down
My opinion is that you are wasting your money. The only supplementation I recommend for long term vegans is 1000mcg sublingual methylb12 per day for life and 2000IU vit D per day when your skin does not get enough exposure to sunlight. Nothing more.
Which brands are you taking ilan? I took B12 tablets (not sublinguals) with minimal effect and have just recently had my first course of injections, but am considering trying sublinguals to maintain my new levels.
Any brand should be fine, I happen to take Solgar 1000mcg tablets.
ilan, you should post the brand you used in your original thread so for those wishing to go down that route can get the right brand and fingers crossed, it works.
I am doing exactly this to fill the holes on cronmeter both D and B-12 are 0's also noticed zinc was light but foods that have high zinc on a vegan basis tend to be fatty ones like nuts and seeds stopped drinking fortified soy milk so some holes popping up

wondering about zinc (different topic)
Zinc requirements are probably low when you're eating fruit since I think it has a highly absorb able form of it. 5 - 7mg should do it. If you're still struggling to get that, then you should be eating more I guess
