how long does a b12 injection take to kick in It For Injections Work? How Long Does It Take

Real medical staff

As we can intuitively grasp, these high levels arent a sign of B12 toxicity or overdose

Common reasons for deficiency include: Low intake particularly diets low in whole grains, legumes, leafy greens or animal products Gut health issues like low stomach acid, SIBO, coeliac disease, IBD, or other factors affecting absorption Medications such as the contraceptive pill, metformin or antacids, which can deplete B vitamins Chronic stress increases demand for certain b vitamins, including B5 and B6 Vegan or vegetarian diets higher risk of B12 deficiency, which can be corrected through supplementation Genetic reasons some mutations on certain genes can increase a persons need for B vitamins This is why I always recommend testing before supplementing

Typically, B12 injections are administered once a week
