I struggle with Rheumatoid arthritis, so I depend on Joint-4 to get me through the day. I notice a visible difference in how stiff and painful my joints are when I'm off this product.

Mike Hamel

Joint-4 has helped my athletic career tremendously. I have had tons of injuries throughout my lifetime that this supplement has helped with. I used to live off of Tylenol because of my constant pain. That has completely stopped since taking Joint-4.

Maddie Chaffee

After graduating college and leaving collegiate soccer I was in pain. I always thought joint supplements were for older people and I didn't think I could benefit from it. I was surprised to see my knee pain fade away! Joint-4 is now a staple in my supplement routine and will continue to be for years to come!

Works great!

I started having hip pain about a month ago. It got so bad that it didn't just hurt when going upstairs but also when sitting and sleeping. After only taking this for a few days the pain decreased significantly. I've been taking it regularly now and I am now able to get back to my workout routine.

Hi AP,

Won’t live without XENDURANCE

I have been taking XENDURANCE 4-joints for over 15 years. I’ve had arthritis since childhood and in constant pain. Had many surgeries but nothing helped until my neighbor told me about her husbands family in Germany that she orders for as they were having trouble getting XENDURANCE 4-Joints, so she gave me the contact info. I ordered and in a short time my pain was gone. It’s all natural and works. I’m now in my mid 80’s and still walk 2 to 3 miles a day, do my yard & house cleaning. I’m taking XENDURANCE as long as I live.


Filled with the essential vitamins I need for my knees. Very happy to find this product.

Feel young again!!

I have been having pain in my knees when running and his not improved no matter what I took until now. I took as instructed and in about 30 days I am back to normal running and training for a 1/2 marathon to celebrate turning 50 this month! I recommend this to everyone!

Impressive! We're so happy to hear that Joint-4 helped you get back on track. We hope that you'll continue to use it to help improve your overall fitness and well-being!

Feel Amazing!

I started taking Xendurance products a couple months ago and haven't looked back since, they have helped with my recovery and endurance more than I could've ever have imagined. I'm sleeping better, making longer strides in the gym and in my running routine. Super grateful for these supplements!
