Helping Your Horse Gain Lean Muscle Mass and Build Topline

view of a horses back topline

Question: A judge at the show said my horse needs to “bulk up,” especially on his topline, but my vet said his weight is fine. What’s up with that?

Answer: Sounds like your horse is fine weight-wise, but he could use a little more lean muscle. Adding more calories from hay or grain could result in unwanted weight gain. Instead, try adding amino acids like those found in SmartMuscle® Mass, which includes limiting amino acids proven to improve topline condition in horses of all ages.

Question: Mass, huh? Is that gonna make my horse fat?

Answer: Nope. SmartMuscle Mass uses the building blocks of lean muscle tissue to help your guy fill out the healthy way!


Question: My Thoroughbred mare really needs to fill out, but increasing her grain is making her crazy! Help!

Answer: You should consider SmartGain®. It contains healthy fats for a “cool” source of calories (i.e. no more crazy horse) plus ingredients to support your mare’s muscles, digestion and appetite.
