ABBOTT PARK, Ill. — Abbott has introduced two new nutrition shakes, Ensure Muscle Health and Ensure Clinical Strength, which are designed to responding to the growing needs of America’s aging baby boomer population.

The company said Thursday that Ensure Muscle Health shakes provide Abbott’s proprietary ingredient, Revigor, a source of HMB (beta-hydroxy-beta-methylbutyrate, an amino-acid metabolite), and 13 grams of protein to help rebuild muscle and strength naturally lost over time.

Meanwhile, Ensure Clinical Strength shakes offer focused clinical nutrition coupling the benefits of Revigor and protein with Immune Balance, a blend of prebiotic fiber to support digestive tract health and antioxidants to support the immune system, according to Abbott.

The Ensure Muscle Health shakes come four flavors (creamy milk chocolate, homemade vanilla, strawberries and cream, and banana cream), and the Ensure Clinical Strength shakes are available in three varieties (creamy milk chocolate, homemade vanilla, and strawberries and cream).

Besides adding two new nutrition shakes, Abbott said it also recently relaunched the Ensure line with a new, streamlined look. The Ensure brand now sports an updated logo and bold packaging, which the company said makes it easier than ever for consumers to find the Ensure shake to fit their nutritional needs. Products in the line include Ensure Muscle Health, Ensure Clinical Strength, Ensure Immune Health, Ensure Bone Health, Ensure or Ensure Plus.

Ensure shakes are available at pharmacies, drug stores, supermarkets wholesale clubs and mass merchandisers nationwide.
