Depends: At your age if your intestinal track works okay you eat fish, chicken or meat at least three times a week, and you don't take any medicines like a proton pump inhibitor like Prilosec for heartburn then you probably don't need any extra B12. Your doctor can confirm if you need.

The amount!: If you can absorb b12, the mdr is 5 mcg. If you cannot, the rexcommeded dose is 2500 mcg, which is 2.5 mg. Yet this small amount is 466 x the mdr!

Yes: In fact, it might be a good idea. Crohn's patients who do not have good control may have trouble absorbing B12 in the termal ileum. Your physician is a good guide here.

What medication?: You haven't supplied any info about the medication you're talking about. Although the risk to your health would be low, it's hard to answer correctly without that info. Some meds shouldn't be combined with B12 for absorption reasons, etc. If you want us to try again, re-ask and include the medication you're wondering about.

Is it safe to take vitamin b12?

Depends on why...: Also, depends on dose. If a person has a very balanced diet, then he may not need to take a daily vitamin because his foods contain enough. Doctors may recommend each person take a multivitamin because many people don't have a truly balanced diet. Some people need extra vitamin D, vitamin B12, calcium, folate, omega-3, etc..., depending on individual issues. Usually, there are no side effects.

Is it possible to take excessive vitamin b12?

Dr. Karen Lawson
Internal Medicine 46 years experience
No: This is a water soluble vitamin and the body will lose excess by urination. However moderation is an important rule of thumb and there is no reason to take more than 1, 000 units a day even in documented deficiency.
