cakana:Is there any reason not to use the human joint supplements?
In most cases, I would think that the human supplements are superior. The reason I choose to give pure Glucosamine & MSM (human) is that they are pure and in powder form, as well as, high quality and less is more - 450 mg in a teaspoon. The only thing that concerns me about most human supplements is - if they are in the form of capsules or tablets - what the coating, fillers or binders might be (or inactive ingredients).
Supplements will vary widely on the quantity of active ingredients per dosage. With Myrika having HD, she is supposed to receive 2500 mg of Glucosamine per day. The pure powder I am getting from the herbalist is the highest quantity & quality per dosage I have found.
