A good multivitamin, super B-complex, 2000 mg of fish oil, 1 tbsp of Apple Cider Vinegar (get the version with the "mother") daily are recommendations I give to all men I train especially if you're over 40. Most people are deficient in Vit D and Magnesium also so adding them in is a good idea. Go with Magnesium Citrate around 200 mg (the other versions will cause stomach issues). If you add these things in I guarantee your blood work looks better at your next annual physical even if don't do anything else for your health.
