Fosters and Smith Vitamins and Omega-3 supplements good or bad?

Vets barely scratch nutrition in school therefore are a shot in the blind as far as nutrition goes (which is why most of the sell Science Diet). Omega 3 is ALWAYS good, never be afraid of Omega 3! But, some dog vitamins have too much calcium. I give my dogs a daily vitamin but I don't give them daily, lol. I give them once a week. 50mg of calcium is a lot if your dog has a diet that already supplies all the calcium it needs daily (like my dog's diet because I feed raw)...see what I mean? Most dog foods also give a dog all the calcium required because dog food companies dump vitamins and minerals in dog food because after it's been cooked twice at high heat most of the vitamins, minerals, and essential amino acids have been burned off rendering dog food with nearly no nutritional value. The way I put it is dog food keeps the dog's stomach feeling full and the vitamins and minerals that they dump into the dog food keeps him alive.
