H2 antagonist or proton pump inhibitor is well advised to do oral B12 supplementation, especially if older than 50 years.

B12, like most proteins and protein-bound nutrients, needs the action of stomach acid to be broken out of food and absorbed, and people on these acid-reducing meds for significant periods of time do risk deficiencies, especially if they already may be predisposed.

I am, at least, seeing references to possible B12 deficiencies in the warnings about these meds lately.

Amen Brother!

In addition to B12, folate also appears impacted by these drugs...... In the last year or so it has really come become clear to me how much the general public is unaware of these issues. It gives me some solice knowing that we can freely discuss these issues on an open forum. Hopefully more people will discover these topics and use them to their benefit by doing futher research like many of us have done within this community.

The list "so far" of nutrients negatively affected by acid blocking drugs is:

Protein digestion impaired
B12
Folate
calcium
magnesium
zinc
iron

These are the ones so far that require an acid environment to
be absorbed correctly as nature intended.

There are reports of a drug on the PN causation lists which is also quite toxic to the bone marrow, showing up in shrimp that are farmed in Thailand and other countries.

This drug is still available as Chloromycetin for rare, life threatening disease states, but was removed from sale in most countries otherwise in the 70's due to its toxicity.

Horse meat:

This article details why horse meat may be dangerous, and it lists chloramphenicol and nitrofurans (this is Macrodantin/Macrobid a drug used in humans for bladder infections) may be present in the meat.
The article is pretty complex, but if you use the search function in Windows edit=find...you'll find the warnings.
