Study Summary

Astaxanthin is a natural compound, present in many foodstuffs and available as a nutritional supplement that has been shown to have beneficial effects on many of the features of insulin resistance/glucose intolerance, at least in animals. The goal of this project is to provide a validation of astaxanthin effects on metabolic regulation in humans and their mechanism(s) of action, to determine if astaxanthin could have any value as a "neutraceutical" to help improve regulation of glucose and fat metabolism in subjects with insulin resistance/ glucose intolerance.

Primary Outcome

Change from baseline insulin sensitivity during hyperinsulinemic/euglycemic clamp at 6 months.
