INTRODUCTION

Calcium Gluconate is the calcium salt of gluconic acid, an oxidation product of glucose, and contains 9.3% calcium, which is about one-third of the calcium in the strength of calcium chloride. It is an ingredient found in a variety of supplements and vitamins and is used to lower potassium in the blood. Calcium gluconate is used as a mineral supplement and medication when there is insufficient calcium in the diet. Supplementation may be done to treat or prevent osteoporosis or rickets, consequences of hypocalcemia.

Manufacture
It is made by mixing gluconic acid with calcium carbonate or calcium hydroxide
