Protykin® Mimics Calorie Restriction

Calorie Restriction is Well Studied to Support Healthy Aging

Caloric restriction slows several aspects of the aging process, including age-related health issues. The wide scope of these actions, and the possible health benefits have led to efforts to find a natural compound that mimics the effects of a calorie restricted diet.

Protykin® may help support healthy aging.

Just 8 mg a day of Protykin® delivers 4 mg of trans resveratrol and is for use in dietary supplements and food and beverage products.
