Before I started using this product I use to wake up in the middle of the night with severe back pain and stiffness in the back. After using Now foods Devil Claw for over 3 months, I rarely wake up in the middle of the night from any back pain discomfort. This item has really helped me out. 2 thumbs way up for this herbal supplement!
