I've been prescriped 50,000 iu vitamin d2 plus 5000 mcg b12, is that safe?

Who prescribed?: It would be prudent to talk to the doctor who prescribed these. In general vitamin D3 is better than D2. You can safely take about 4000 units of vitamin D3 daily. Taking B12 orally may not work if you cannot absorb it. If you are prescribed 5000 mcg/day that is far more than you need. Let me reiterate, talk to your doctor, if you do not have a rapport with him/her, see a new doctor.Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. 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, if you have sex.
