A daily multivitamin/mineral is a good place to start. ...Read more

B12 deficiency. I take cobalamin. Should I be taking Methylcobalam instead?

Methylcobalamin best: You must be taking cyanocobalamin (most common) or hydroxocobalamin. These are both effective but methylcobalamin has some significant advantages and is the optimal form to take if possible.

What meds are available for B12 deficiency? What are side affect of each? (injectible meds my B12 levels were 169). Thanks

Methylcobalamin: Injectable B12 is the surest way to increase your B12 levels. Injections are usually administered weekly, but I occasionally prescribe them on a daily basis. Methylcobalamin is the most bio-available form of b12, but is slightly more expensive than the traditional cyancobalamin form. Sublingual methylcobalamin is the next most effective way to restore tissue B12 levels. No adverse effects. ...Read more

If I eat a flexitarian diet like Okinawans, Japanese, & some Africans do will I avoid b12 deficiency like they do? Or do they have B12 deficiency?

Animal protein: I do not know what these diets are. To have adequate intake of B12 you need to consume animal protein, keeping in mind that milk is an animal protein. 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 or alcohol in any form.

Once you have a B12 deficiency and take monthly injections, will that be the case for the rest of your life or will you be able to stop injections?

To stop would put you at risk for anemia and severe neurologic problems like neuropathy, difficulty with balance and walking, "megaloblastic madness", and death. Sometimes, patients can take high doses of vitamin B12 1-2 mg orally once daily instead of the shots. Ask your doctor if this is possible for you. ...Read more
