Hi,
Glucosamine chondroitin is a nutritional supplement that used in treatment of
osteoarthritis and prevention of further bone fractures. It is also used to treat temporomandibular joint disorder, cataracts,
hypercholesterolemia, urinary tract infections etc. Glucosamine chondroitin causing
muscle weakness or cramping isn't found in evidence based studies but this doesn't mean no side effects on muscles exist.
Potassium gluconate is a nutritional supplement that is used in the treatment and prevention of
potassium deficiency in the body. However, it may cause muscle weakness or limp feeling, cramping, twitching etc., as side effects. Other side effects of potassium gluconate are leg discomfort, numbness, tingling or twitching sensation in the hands and feet, nausea, GIT upset, anxiety, fainting, confusion, vomiting, diarrhea, abdominal pain, increased thirst, increased urination etc.
Take care. Hope I have answered your question. Let me know if I can assist you further.
