Ester-C is the 3rd generation of Vitamin C. It is developed in the form of Calcium Ascorbate that is non-acidic and safer for people with hypertension and kidney disorders as compared to Sodium Ascorbate.
It contains active Vitamin C metabolites including L-threonate, which facilitates 400 times faster absorption, clinically proven higher bioavailability and 24 hours protection of the body.
Calcium ascorbate generally provides 90-110 mg of calcium (890-910 mg of ascorbic acid) per 1,000 mg of calcium ascorbate. Calcium in this form appears to be reasonably well absorbed.
The recommended dietary calcium intake for adults is 1,000 to 1,200 mg/day. Total calcium intake should not exceed theUL, which is 2,500 mg/day for adults aged 19-50 years and 2,000 mg/day for adults older than 50 years.
