One theory is that mental health problems are caused by high homocysteine levels (vitamin B12 is needed to break down this chemical)
B12 is frequently paired with MIC injections and medical weight loss injections to support metabolism and energy during a weight-management program
Risks The NIH reports that in those with confirmed deficiency, B12 injections can have important benefits
Who Can Benefit from Vitamin Injections Vitamin injections are great for just about anyone who wants to feel better and function at their best, including those who: Struggle with fatigue or low energy Follow vegetarian or vegan diets Experience poor nutrient absorption Deal with stress or burnout Are recovering from illness or surgery Want to boost overall wellness and vitality Theyre also a convenient option for people who find it hard to stay consistent with daily supplements
In adults and older children, the total volume used should also stay within safe limits animal studies suggest up to about 30 mL (the full vial) can be given to an adult without benzyl-alcohol toxicity, but one should still use only the amount needed and discard the rest if sterility is lost
These results suggest that sublingual and oral B12 supplementation may serve as viable alternatives to IM injections, particularly in clinical settings where frequent intramuscular administration is impractical or resource intensive
