Tag: B12 warnings

While vitamin B12 is essential for numerous bodily functions, studies have shown that high doses, often from injections, can cause side effects like acne and anxiety in sensitive individuals. Most healthy individuals do not experience negative side effects of vitamin B12 when consuming it at recommended levels from diet or oral supplements.

While excess B12 is water-soluble and often harmlessly excreted, abnormally high blood levels, especially without supplementation, can signal serious underlying diseases like liver or kidney issues. This makes it crucial to understand who should not take a B12 supplement, as it could otherwise mask symptoms or lead to adverse effects.
