Have taken Osteo Bi-Flex for over 5 years.Decided to try Instaflex Advanced to see if it might work better.
Instead of getting caught in the automatic re-orders, I bought the 14 pill bottle at Walgreens and dropped the Osteo. Tried a second 14 pill bottle hoping results would improve. Cost is $2.00 per pill. Results never improved so I went back to Osteo.
I take the triple strength 2 pill a day Osteo that I buy at Sam's club for $27.99 for 190 tablets. That works out to just under 30 cents a day.
I'm a very active 66 year old and have had three knee surgeries, not all on the same knee.Wish results had been better, but for now, will stick with the Osteo Bi-Flex.
Reason of review: Not as described.
