Material & Methods: Forty healthy menstruating regularly women, around 18-34 years of age, participated as subjects in our study. Estimation of serum inorganic phosphorus, uric acid, calcium, and magnesium were done by UV Molybdate (End point assay), Modified Trinder Peroxidase method, O-Cresolphthalein-Complexone method, and Calmagite method. Sodium levels were analyzed by Neochem Sodium-Potassium kit (Colorimetric Method). Results: The mean serum inorganic phosphorous level in menstrual phase (4.11¡À 0.40) was significantly higher as compared to proliferative phase (3.64 ¡À 0.44) and secretory phase (3.23 ¡À 0.54). The levels of serum uric acid were significantly decreased (p < 0.05) in secretory phase whereas serum calcium level was increase in the proliferative phase. The serum magnesium level was significantly decrease from menstrual to proliferative phase (p
