For me, it was bad.
I did not have a good result with this product. I also have neuropothy in lower legs and feet and taking Instaflex caused that to be much worse so I stopped taking the Instaflex. I am sure it would be great for those who only have bad knees. I did not notice any improvement in the knees while I took the Instaflex for about six days.

Instaflex for Joint Relief
I found if I take one tablet a day I do receive relief from my knee joint problems.

Do Not Order This from TV ADD!!! Like the Product a lot !
Instaflex- has helped me considerably-- I would and have recommended this product to many friends.
I do not recommend ordering it from anyplace but GNC-- I ordered it from a television commercial - free sample, you pay for shipping, then the auto deliveries started I was charged$ 74.99 for some months --promised price was $49.00 still more then GNC--be careful-- very unhappy with this TV COMPANY-- I have contacted them 3-4 times for records-- because I did not receive- all the products I was billed for-- their number is 800-436-0920-- do not use them !!!!

So far I have not noticed a difference. I still have pain in all my joints. The hips are the worse and they remain the same. Ask me again at the end of 30 days.

Not that good
Compared to Instaflex Advanced, this delivers very little in the way of joint relief.

This one works for me.
I tried several brands before I found this product. Instaflex works for me. Arthritic knees are so scary. You never know when you will twist, turn, jerk and be in pain for days, or worse be in the bed.
I have lost weight, been to PT, and take Instaflex. All of this means, right now, I am able to climb steps and walk without pain.
Exciting stuff for me.
I take it twice a day.

Just bought a btl for my husbands hip & knee pain
After reading reviews the joint supplement has helped reduce some pain with people from all ages with knee, hip, shoulder, & even back problems. If you have torn ligaments or a slight tear in the meniscus this will only prolong surgery. I just want to add you should exercise with caution this does not repair any tears or broken bones it just helps with pain.
