The linear regressions of kidney functions including renal plasma flow creatinine clearance and protein synthesis have shown with age. A decrease in the functions of the endocrine system and reproductive organs are also observed with age. It has been reported that Kidney deficient persons have higher blood lipid peroxide (LPC) levels in comparison to non Kidney -deficient persons.

The Kidney formula was able to decrease the serum LPO levels and increase SOD activities in blood and brain tissues.
