The reason I was wondering this was because of Natasha St. whatever her name is. She said in her videos that she had been taking B12 oral supplements for years and tested dangerously low afterwards.
Knowing that Durianrider is a big proponent of the shots and other people cite studies saying that sublinguals are just as effective, I'm wondering if anyone in our community has experienced taking b12 pills yet later testing too low.
This is a good question, isn't it? thanks guys!
thank you for the advice. It's not an issue though. I'm honestly trying to learn the answer to the question I posed, if some people have diligently taken sublinguals and not absorbed B12 like what Natasha claimed.
Somewhat of a poor question because there was somebody here who said they did, but turns out they used them only rarely. If you're trying to cure a deficiency, you probably should use them every day. That study mentioned that even WITHOUT intrinsic factor, 1% of b12 is still absorbed orally (closer to 100% sublingually of course). People just don't take enough, simple as that.
thank you for the judgement on the question itself- very helpful!
The question specifically is asking for feedback from community members. I'm trying to figure out if what Natasha said was truthful. I don't think she'd lie but there could have been some complications like she simply wasn't taking enough.
I tested low two summers ago. I got six shots at first, and then I switched to sublinguals. Last summer I tested at the top of the normal range, so I'm sure they're working for me. I'll check again this summer and post if not, but I'm confident that I'm fine. I have another friend (he's a member here and might weigh in and I know him in real life too) who also tested low and only did the sublinguals and then tested fine, so they worked for him too.
I'd love an answer on this topic as currently sublinguals are my only option. The only way I could get shots would be if someone in another country bought them and mailed them to me!
I recon that if sublingual's where effective Dr's and hospital's would be offering them as an alternative to injections, seen that most "patients" would jump on the option to take a grape flavored vitamin pill over a "painful" injection, fact is they don't. I recon because it is questionable if sublingual's are actually effective.
Also the reason why B12 deficiency is very common under meat eaters, is because they lack the ability to absorb B12 through their digestive track. B12 deficiency is defiantly not a Vegan only problem.
Sublingual's are only going to work for you if you don't have B12 digestive/absorption issues. B12 shots defiantly work period because they don't pass you digestive track and go directly through your muscle to your blood.
I recently switched from taking B12 sublingual's to giving myself shot's and I can defiantly feel the difference in my running and fitness.
B12 sublinguals work for me, at least the brand I buy works! I think the brand you buy is very important. I have tried so many brands across the years and the brand I use is the one that started working for me!
Also, doctors love giving shots of anything, especially if it is preventative, like "vaccines." To "treat," they love handing out pills and liquids.
Sublinguals are starting to become a subject of conversation, as I learned in my clinical nutrition course this past semester.
Yes they do. That's why you keep them under your tongue to absorb right into the bloodstream. And the reason hospitals don't offer them is probably because they're not an immediate fix like a shot is, and they're not prescription drugs. They work just fine - there are many studies documenting this, not just anecdotal evidence.
Existing evidence does not suggest any differences among forms with respect to absorption or bioavailability. However the body’s ability to absorb vitamin B12 from dietary supplements is largely limited by the capacity of intrinsic factor. For example, only about 10 mcg of a 500 mcg oral supplement is actually absorbed in healthy people
In addition to oral dietary supplements, vitamin B12 is available in sublingual preparations as tablets or lozenges. These preparations are frequently marketed as having superior bioavailability, although evidence suggests no difference in efficacy between oral and sublingual forms [16,17].
Vitamin B12, in the form of cyanocobalamin and occasionally hydroxocobalamin, can be administered parenterally as a prescription medication, usually by intramuscular injection . Parenteral administration is typically used to treat vitamin B12 deficiency caused by pernicious anemia and other conditions that result in vitamin B12 malabsorption and severe vitamin B12 deficiency .
Vitamin B12 is also available as a prescription medication in a gel formulation applied intranasally, a product marketed as an alternative to vitamin B12 injections that some patients might prefer . This formulation appears to be effective in raising vitamin B12 blood levels , although it has not been thoroughly studied in clinical settings.
