The Impact of pH on Bone Cell Function and Acid-Base Balance in Osteoporosis
This article explores the relationship between extracellular pH levels and the functioning of bone cells, particularly osteoblasts and osteoclasts. It discusses the consequences of acidity (pH ≤ 7.0) and alkalinity (pH ≥ 7.4) on bone health, mineralization, and maintenance. A focus is placed on how deviations in pH affect the balance between bone formation and resorption, leading to conditions such as bone loss and osteopenia. Understanding these mechanisms may help in developing strategies for preventing bone-related disorders linked to acid-base imbalances.
