Hey everyone! I've been reading a few sites and I'm just getting more confused. I just recently put Midnite on Glucosmaine 1000mg and Chondroitin 800mg (human grade). Should I add vitamin C? If so is ester-C better? What about Magnesium, MSM, Selenium and vitamin D? Midnite weighs about 48lbs. if I should add these supplements these are the amounts that I figured for some of them, tell me what you think? vitamin C/ester-C: 1000mg Magnesium: 30mg MSM: I believe comes in capsule form-give 1 capsule Selenium: 50mg vitamin D: not sure?? It just seems like a whole lot of supplements and I'm wondering if I just should stick with the Glucosamine/Chondroitin and just add the ester-C since its human grade. I'm a bit confused :/ Thanks again!
