Muscle stiffness and back pain which due to work stress have been bothering me for years. As most of the time I do require a pillow to support my back while dining at the restaurant. At one time, while I was having lunch with foreign guest, I was advice and introduce to consume Naturion collagen with 2 sachets per day for about 2 months. I’m feeling great now, more energized and no more back pain. I’m reordering Naturion Collagen for myself and as a gift to my father-in-law to reduce his joints problem.
