Study Summary

This trialwill test if supplementing with acetate can reduce risk of cardiovascular diseases in adults over 50.

Who is the study for?
This trial is for adults aged 50+ with low fiber intake, stable weight, and normal serum phosphorus levels. They must not be pregnant or planning pregnancy, have a BMI over 40, take calcium supplements, or suffer from serious chronic diseases like heart disease or diabetes.Check my eligibility
What is being tested?
The study tests if a 12-week oral acetate supplement can improve arterial function in older adults by reducing oxidative stress and increasing nitric oxide. It compares the effects of Calcium Acetate Oral Solution to Calcium Carbonate Oral Suspension.See study design
What are the potential side effects?
Potential side effects may include digestive discomfort due to the supplements and possible changes in blood mineral levels. The safety profile will be closely monitored given that participants are older adults.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: AcetateExperimental Treatment1 Intervention
Subjects will be orally supplemented with calcium acetate for 12 weeks. Subjects will be instructed to take a volume of the oral liquid solution that contains 1,334 mg of calcium acetate 3x per day with meals, for a total dose of 4,000 mg/day. Calcium acetate will be compounded by the CU Anschutz Medical Campus Research Pharmacy and dispensed to subjects in 4-week supplies.
Group II: PlaceboPlacebo Group1 Intervention
Subjects will be orally supplemented with calcium carbonate for 12 weeks. This placebo has been selected to match any potential effects of calcium and phosphate binding of the calcium acetate, i.e., we will isolate the effects of acetate. Subjects will be instructed to take a volume of the oral liquid solution equal to that of the calcium acetate group 3x per day with meals. To match the amount of elemental calcium between calcium acetate and calcium carbonate, this dose of calcium carbonate will contain 833 mg of calcium carbonate, for a total dose of 2,500 mg/day. Calcium carbonate will be compounded by the CU Anschutz Medical Campus Research Pharmacy, visually identical to calcium acetate including the packaging, and dispensed to subjects in 4-week supplies.
