I have a 10 yr old 60 pound yellow lab with sore joints. I have been using joint supplements (glucosamine) for dogs, and am considering switching to a human supplement for cost reasons. The supplement I’m considering using has more than glucosamine, and I’m wondering if this is safe: 3 tablets (the serving size for humans) contain 300 mg Calcium (as calcium carbonate), 1500 mg Glucosamine HCL, and 170 mg of a "proprietary blend" which includes Ginger Root Extract (Zingiber officinale), Green Tea Leaf Extract (Camellia sinensis) and Enzymes (Bromelain and Papain). Other ingredients include: Microcrystalline celluluse, stearic acid (vegetable), croscarmellose sodium, hydroxypropyl cellulose, cellulose, glycerin, magnesium stearate (vegetable), and silicon dioxide. The product states that it contains shellfish (crab and shrimp). Is this product safe for dogs? If so, how much should I give?

I know this is asking a lot, but is there a multivitam that contains all the essential nutrients at the RDA level, or at the very least, the below nutrients.

I know I can buy individual supplements to catch each of the nutrients listed below, but if there was say 1 or 2 multivitamin tablets that contained all the nutrients, that would be great.
