Not too high: Your B12 level while high is not abnormally high. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.

Because there are no side effects from large doses of vitamin B-12, no tolerable upper intake was ever established. Elevated B12 levels can be seen in normal patients and in patients taking Estrogens, Prilosec and Vitamin A. Can also be elevated in several disorder
