According to Stanford Chiropractic Centre, benefits of apple cider vinegar for arthritis include:
Mineral deficiencies in the body can make joint pain worse. Because Apple Cider Vinegar contains the calcium, magnesium, potassium, and phosphorus your body needs, it helps as a supplement and therefore reduces pain.
The magnesium in apple cider vinegar helps bones absorb calcium, which is essential to bone strength.
Apple cider vinegar also contains antioxidants, beta-carotene, and acetic acid. Antioxidants block the damaging effects of free radicals, preventing the cell and tissue damage commonly found with degenerative conditions like arthritis.
