About AminAmend™
AminAmend™ is a nutritional supplement designed to support healthy muscle mass and function as pets age. AminAmend™ contains HMB and Vitamin D3, a proven and clinically tested combination that prevents muscle protein breakdown and supports muscle protein synthesis. With age, the amount of HMB produced by the body decreases with muscle health.
HMB has been clinically tested and used to improve muscle mass and function in humans for over two decades. Specifically formulated for companion animals like cats and dogs, AminAmend™ improves pets’ quality of life and lifespan by keeping them healthy and mobile as they age.


Complements a healthy diet by enabling the body to better utilize the protein found in foods to build and maintain muscle.



Supported by more than 20 years of clinical research and safety in humans. A human innovation adapted for cats and dogs.

Helps to prevent age-related declines in muscle strength and mass.
