What’s the difference between MYOS Original and Vet Strength?

MYOS Original contains pure Fortetropin® — a natural egg-yolk–derived ingredient clinically shown to support healthy muscle mass. It’s ideal for general muscle maintenance, aging pets, and everyday mobility support.

MYOS Vet Strength includes the same Fortetropin® base plus added BCAAs (leucine, isoleucine, valine) for enhanced muscle recovery and rebuilding. It’s designed for pets with more significant muscle loss, those in rehab, or high-performance working dogs needing extra support.

Simple. Natural. 
MYOS uses a single, all-natural ingredient called Fortetropin®, derived from egg yolks. No additives or artificial ingredients. Fortetropin® has been shown in multiple clinical studies to accelerate gains in muscle mass, improve mobility and enhance recovery from injury.

- Muscle supports joint and skeletal health. Strong muscles stabilize joints, reducing the risk of secondary injuries.
- Muscle mass contributes to metabolic health. It plays a major role in insulin sensitivity and nutrient utilization.
- Muscle impacts recovery outcomes. Animals with better muscle tone typically recover faster from surgery or injury.

The MYOS Muscle Formula is perfect for:

- Senior pets with noticeable loss of muscle mass
- Post-operative patients to support recovery
- Inactive or mobility-limited animals due to arthritis or neurological issues
- Performance animals looking to maintain optimal muscle conditioning
