Greetings. Supplementing the nutrition with certain vitamins and elements is a good idea. You can check your vitamin B12 and Vitamin D levels , and replenish them. Other supplements can be taken based on the effects you wish to see. Alternatively you can rotate the multivitamins and other products to derive maximum benefit and assure that you are not duplicating any. Too much of supplements can be harmful as well. A reasonable gap should be there.
