A good protein powder, glutamine(you can buy protein powder with glutamine in it to try to kill two birds with one stone if you really need to cut costs), a good omega oil combo such as Udo's Perfected blend(has omega 3,6.9 oils) and a multi vitamin. I take a liquid blend with antioxidants that absorb faster than capsules. Oh. Because I had surgery on my right knee, I use MSM and glucosamine for the joints. Since it's just me, I buy the big sizes and it lasts.
