I am a healthy but very stressed (work related) 33 year old male. I workout 3-4 times a week and take suppliments to help with muscle gains (mostly pre workout energy, Creatine and Nitric Oxide, multivitamins), and also am on a high protein diet. I have had blood tests due to unusual fatigue, and my kidney enzymes came back elevated. Any reason for this due to the diet or suppliments? I drink plenty of water, eat a lot of fruits and veggies.
