Key Evidence #1
Public scholarly dataCitation signal: 141
observational

In patients with knee OA with at least moderate subjective improvement with prior glucosamine use, this study provides no evidence of symptomatic benefit from continued use of glucosamines sulfate.

Key Evidence #2
Public scholarly dataCitation signal: 160
observational

Chs3p-dependent chitin synthesis in S. cerevisiae is regulated both by the levels of intermediates of the UDP-GlcNAc biosynthetic pathway and by an increase in the activity of the enzyme in the plasma membrane.

Key Evidence #3
Public scholarly dataCitation signal: 60
observational

Circuit style resistance-training and weight loss improved functional capacity in women with knee OA and functional aerobic capacity was increased to a greater degree for those in the HP and GCM groups while there were some trends suggesting that supplementati
