B12 shots for malabsorption or dietary restriction Vegans, vegetarians, older adults, and people with GI conditions (Crohn's disease, celiac disease, pernicious anemia) commonly have inadequate B12 absorption
And while adequate B12 levels are essential for good health, research has shown that additional intake will not provide additional health benefits for those who are otherwise healthy
A B12 shot is a quick intramuscular injection of vitamin B12 (cobalamin) that bypasses the stomach acid, liver metabolism, and intestinal absorption issues that limit oral B12 to roughly 1% bioavailability in most adults
Drinking too much coconut water can be dangerous, particularly for certain people
By restoring cobalamin levels, these injections help support healthy red blood cell production, neurological function, and DNA synthesis
