Cognitive Function: Adequate B12 levels are linked to improved memory and reduced risk of cognitive decline

If anything, most studies seemed to trend towards higher B12 levels being protective, as you can see below and at 2:03 in my video

The METAOD005 12-week murine study used 300 models across five concentration groups plus one control group and reported a statistically significant mean mass reduction in one peptide-exposed group with improved lipid markers, again limited to obese models

People with gastrointestinal conditions : Individuals with conditions such as Crohns disease, celiac disease, or those who have undergone gastrointestinal surgery are at higher risk of B12 deficiency

Some common signs include weight loss, anemia, lethargy, and loss of appetite

I have no hard evidence , just what Ive read on this forum for over 9 years
