Glucosamine, Chondroitin & MSM

Does anybody give theyre older dogs human grade glucose supplements? After several months of buying the $15 90pill bottle of dog glucose @ wal mart for a few older dogs, I decided to get smart and walk down the human supplement isle. I found a brand of gel caps that has 1500mg of glucose, 1200 mg of chondroitin & (I believe) 500mg of msm.
Now, the one ive been giving labled for dogs is 650mg of glucose, 250mg of chondroitin (& I cant exactly remember the dose of msm), but ive been giving 2 pills daily (so double the serving listed, as labled per weight of dog). So I know im ok with the amount of glucose in 1 human grade pill. Its the amount of chondroitin & msm that scares me. My question is am I ok to go this route vs the stuff labled for dogs? As far as chondroitin & msm, how much is "too much"? 4 older dogs on cosequin adds up really fast! However if I am indeed able to go this route I can get over 300 capsules for a fraction of what im paying for the other stuff. Thanks in advance for your time & concern.

Crisis,

I've used the human grade joint supplements for years. You can always buy those products individually if you don't like the dosages they come in combined.

I was using Synflex for humans and it worked very well. I was told by several medical people that the liquid joint supplements worked better because they were easier to absorb so I used those more often.

I used to be able to buy that Synflex inexpensively but then the price went way up. I switched to Liquid Health 5000 and it worked just as well. My old dog had arthritis pretty bad and I did see a difference.

The above links are just to show what those products look like. You can find much cheaper prices.

Try ebay and use google. Countryside Pets used to have good sales on the Liquid Health 5000 and I world buy it by the gallon for about $115 which lasted well over a year for one 50 pound dog.

i ended up going with this one it on its way in the mail.
