My doctor says I have a vitamin deficiency. How can I find out which vitamin I need more of?

Your doctor is right that you may be deficient in certain vitamins, so it's important to determine what those are and how much you need. You should consult with your doctor or healthcare provider to get an accurate assessment of your specific needs. In general, though, the most common deficiencies are Vitamin A, Vitamin B12, Vitamin D, and Vitamin E. Depending on your individual situation, you may also require additional supplementation such as Vitamin C, Calcium, Iron, Zinc, Selenium, Magnesium, and Omega-3 Fatty Acids.
