I'm healthy, active, normal weight, mid 50 lady. I have normal age related cartilage & joint degeneration. No inflammation. Shoulders clicks when rotated, knees click when squatting. it has been like this for a long time. I considered it normal. I started taking Biocell collagen out of curiosity. 2 pills a day, morning and evening, with food. After 5 weeks my knees and shoulders feel better. No clicking anymore. My skin also feels better with regards to dryness and sofness. Forehead wrinkles are not as deep. So far so good.
I will continue to use it. - Maria
