vitamin b12 1000 mcg injection side effects Are Shots Safe? Royal Palm Beach Medical Group Vitamin B12 Side Effects

People receiving high-dose B12 therapy appear more likely to experience skin changes than those taking standard dietary supplements, based on case reports

However, theyre not a standalone weight loss solution

Vitamin B12 helps to metabolize an amino acid known as homocysteine

When sufficient folic acid is available, all known B12 related deficiency syndromes normalize, save those narrowly connected with the B12 dependent enzymes Methylmalonyl Coenzyme A mutase (MUT), and 5-methyltetrahydrofolate-homocysteine methyltransferase (MTR), also known as methionine synthase

For instance, patients with liver disease may experience fatigue, jaundice, or abdominal swellingsymptoms related to hepatic dysfunction rather than the elevated B12 itself
