I was speaking with an elderly man (83) in Florida who suffered from loss of cartilage in his knee. He had hip replacement years back and took forever to heal from that surgery and did not want to do another surgery. A friend suggested he drink half Ruby Red Grapefruit/Orange Juice everyday for awhile. He told me it healed his knee and rebuilt the cartilage.
Grapefruit juice has potential anti-inflammatory and joint-protective benefits due to its antioxidants and flavonoids, which may help with arthritis.
