Saint Petersburg, Florida

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.

I've been using glucosamine sulfate since 1998 and it has helped immensely.Earlier this year I was diagnosed with the gout - glucosamine uses shellfish/fish in their blend - which I have to avoid.

Instaflex advanced doesn't use shellfish/fish so I tried it.

For the last 3 months I have felt slightly better in the knees, back and ankle (gout hit me hard here).So if you're body can handle shellfish/fish I would stay with the glucosamine.


Thanks for the information about Osteo Bi Flex. I had a hip replacement and suffer from arthritis, and have old sports knee injuries. I'll try out the Osteo Bi Flex.
