the 軟骨 of my knee is 退化 and i usually have to stop action 1-2 times during 50 minutes jogging everyday.....i started to have the 七海健駱 2 months ago after the advice of my chiropractor....
lately....although i still feel my knee is uncomfortable but i don't have to stop action during exercise....so i found it is somehow helpful...
regarding 骨骼疏鬆....i don't think it can help as there's no calium at all....i think it's for joint but not for bone
i just tell my experiece.....you may ask those professional again
