Dear Annie: I have had many odd symptoms over the years that got worse, and it has taken much research to finally get help.

I have deficiencies in vitamins D and B12 that require more than a multivitamin. Doctors don’t learn nutrition in medical school and are unaware of what deficiencies look like. Vitamins aren’t part of routine bloodwork.

Please advise readers to request their vitamins, as well as their children’s, be checked when having blood drawn. If deficient, it is important to educate oneself on the possible cause, symptoms and where to get help.

Deficiencies don’t go away on their own and they have health consequences over time. Thank you. — Vitamins Can Be Vital

Dear Reader: Thank you for your letter.

You bring up a very important point about nutrition.

You can get many of your vitamins if you eat a well-balanced diet, but knowledge is power. Learning from your doctor what vitamins you are deficient in could really help your overall health.
