PetAg KMR Healthy Aging is a nutritional supplement designed specifically for adult and senior cats aged seven years and older. It provides targeted nutrition to support the common health concerns of aging felines, including heart, muscle, joint, immune, and skin health.
The standout feature is its high-quality protein content that helps maintain a healthy heart and strong muscles.

Buying Guide: What to Look for in Healthy Aging Muscle Supplements
Cellular Rejuvenation Ingredients
For human supplements, ingredients like Urolithin A, NAD+, and resveratrol are clinically linked to improved mitochondrial function and muscle strength. These compounds help remove damaged mitochondria and promote cellular renewal, which is essential for maintaining energy and muscle mass as you age. Products such as Timeline Mitopure and the liposomal complexes leverage these pathways. If you are interested in combining NAD+ with resveratrol, see our review of the best NR resveratrol stack for healthy aging.
Protein and Amino Acid Support
For pets, high-quality protein is the foundation of muscle health. Look for formulas with easily digestible protein sources, omega fatty acids, and added vitamins. The PetAg KMR Healthy Aging formula provides protein to support heart and muscle function in senior cats. Similarly, the MYOS Canine Muscle Formula uses a patented Fortetropin blend to reduce myostatin, a protein that inhibits muscle growth. Both are vet-recommended and designed for aging animals.
Delivery and Absorption
How a supplement is delivered matters. Liposomal encapsulation, as seen in the Plus+Ultra and HMHDWelltra products, enhances bioavailability so your body can absorb more of the active ingredients. For pets, powders that mix easily with food (like MYOS and PetAg) ensure consistent intake. Always choose a form that fits your daily routine, whether that is softgels, liquid drops, or powder.

Choosing the best healthy aging supplements for muscle depends on your specific goals. For a clinically proven human option that targets cellular renewal and muscle strength, Timeline Mitopure Urolithin A Supplement Softgels is our top recommendation for adults seeking longevity support.
