I was told by a Naturopath that the joint popping was a symptom of mild inflammation in the joints.
My Husband takes a vegetarian glucosamine & MSM supplement made by Blue Bonnet, and also another MSM supplement (to get lots of MSM). If swallowing the capsules is a problem, the powder from the capsules could be mixed with a bite of food, such as apple sauce, to make it easier to get it all down. Anyway, my Husband had very bad joint pain prior to taking the MSM/glucosamine (he has tendon damage & joint degeneration from long-term Prednisone use), but since starting the supplements, he has not had nearly the pain. He was becoming disabled from the pain before, but now he goes hiking in the mountains on weekends without any difficulty.
Also, muscle twitching/cramping could be from a lack of sufficient magnesium, calcium, potassium, and/or water (i.e., dehydration and/or electrolyte imbalance). A daily multi-vitamin/mineral will not give you enough of these electrolytes to meet your body's needs, so you might want to make sure you eat foods rich in these minerals (fruits & vegetables, nuts/seeds, etc.).
I have no financial connection with Blue Bonnet... Take care,
