Can we trust getting an MD b12 injection anymore?
Will big pharma add mrna to simply b12 therapy?
I took a supplement that had high vitamin B12. It gave me heart rate issues. Too much is bad also.
That is why the globalists are pushing plant based food. Less B12, more control over the population.
Bird flu is a hoax just like the scamdemic as well.
Interesting article. Couldn’t find a supplement dosage recommendation in the article though. I am on a typical 50+ mens multivitamin and the B12 is like 1000% of RDA, so maybe not too bad?
Wife and I each take a 5000 mcg supplement each day. You put it under your tongue and let it dissolve. Supposedly you get more B12 letting it absorb into your mouth's membranes. Stomach acid destroys most of it (I guess).
I have a stash of B12, take half a dose now and then, but the label says 1 pill is 200,000% of the MDR and I really don’t feel that needy.
Given the sources of B12 in food, the primary group vulnerable are the stupid (i.e., liberals).
Given my diet, there’s no risk whatsoever.
So, thanks for the health affirmation bump!
B12 is not bioavailable orally, that’s why any elevated doses are useless. Intravenous is a way to go with B12.
It appears that the author of the study did not consider that stomach acid destroys B-12, especially if the parietal cells in the fundus of the stomach that produce the acid don’t also produce “intrinsic factor.”
Thus, people who are taking proton pump inhibitors often are B-12 deficient as they influence the production of acid in the parietal cells.
Intrinsic factor attaches to the B-12 like an enteric coating that stops the stomach acid from destroying the B-12. When the chime from the stomach passes the bile ducts and enters the small intestine, the alkaline solutions from the liver, pancreas, and gall bladder neutralize the acid so the intrinsic factor can dissolve.
Thus if the chime stays acid in the small intestine, B-12 will not be absorbed.
The injections bypass the stomach and small intestine, thus they have been used for years to treat B-12 deficiency.
Problem is, there are medical problems that need to be addressed such as stomach cancer that causes the parietal cells to malfunction, causing the B-12 deficiency.
It is better to find the root cause and treat it, rather than just treat the deficiency.
I think that the B-12 deficiency is the leading cause of depression in the elderly.
People who have intestinal bypass also must address vitamin deficiencies due to lack of absorption.
The G-cells or gastrin cells in the lining of the stomach indirectly cause the stomach to produce acid. I say indirect as the G-cells cause a histamine increase in the bloodstream (they function like a hormone) that stimulates the parietal cells to produce acid and intrinsic factor.
I started taking B12 as a daily supplement a couple months ago and its made a huge difference from an energy perspective.
Vegans would be Deeply Saddened if they weren’t already in Memory Care:
“What are some food sources high in vitamin b12?
ChatGPT said:
Vitamin B12 is essential for nerve function and the production of red blood cells. Here are some food sources that are particularly high in B12:
Animal Liver and Kidneys (especially beef liver) – These organ meats are some of the richest sources of vitamin B12.
Fish – Fish like salmon, trout, sardines, and tuna are excellent sources of B12.
Shellfish – Clams, oysters, and mussels are very high in vitamin B12.
Meat – Poultry, beef, and pork are good sources of B12.
Dairy Products – Milk, cheese, and yogurt are all rich in B12.
Eggs – Especially the yolks, are a good source of vitamin B12.”

WARNINGS about B12
ConsumerLab.com notes that a large study in the Netherlands found that people age 65 and older who took 500 mcg of B12 and 400 mcg of folic acid daily for 2 to 3 yrs. had a 77% higher risk of colorectal cancer than those in the placebo group, and an overall cancer rate 15% higher than those in the placebo group.
A study of middle-aged men found that those with B12 blood levels above 455 pg/mL had an 85% higher risk of dying over the next 8 years, compared to men with blood levels below 339 pg/mL.

Lots of B12 in beer. I’ve got it covered.
