Q I read your recent article on N-acetylcarnosine but was unable to find the product on your Web site. Do you carry such a product, and if not, where can I obtain it?

MOLLY, Silver Spring, MD

A N-Acetylcarnosine is contained in Eye D’Clare II, a sterile eye-drop formulation for reduced irritation and relief from dryness, and more. A comprehensive index of all the ingredients in all Life Enhancement products is being developed and will appear on the Web site (www.life-enhancement.com).
