If you only want one supplement, this is it.
Foundation Formula is the complete daily multivitamin we built to cover what hay and grain leave out. It packs vitamins, minerals, amino acids, and gut support into one premium pellet, so no matter your horse's age, breed, or workload, they get what they need for a shinier coat, stronger hooves, better muscle, and a healthier gut.
The last multivitamin your horse will ever need.
Foundation Formula includes a full set of daily vitamins, the same kind of complete lineup you'd want in your own multivitamin, covering energy, blood health, and overall condition.
Better muscle and a stronger topline
Amino acids are the building blocks of muscle. Without enough of them, your horse can't fully use the protein in their hay, so they struggle to build and hold muscle along the back and hindquarters. Foundation Formula adds the key ones most feeds leave out.
A calmer, healthier gut
Live probiotics and enzymes support the good bacteria in your horse's gut. That means they get more out of every flake of hay you already feed, with steadier digestion and appetite.
A shinier coat and stronger hooves
Biotin gets the credit for hooves, but it doesn't work alone. Zinc, methionine, and omega-3s from flax work together to grow tougher hoof wall and bring out real shine in the coat. All of it is already in the scoop.
Everyday protection
Horses that don't graze on fresh grass are almost always short on vitamin E. Paired with selenium, it helps protect muscles and keep your horse feeling strong day to day. We use forms that absorb well and stay in a safe range.
The Premium Ingredients Doing the Work
Tap any ingredient to see why it's included.
-
Lysine is the number one building block for muscle, and it's the one horses run short on most. Without enough of it, your horse can't fully use the protein in their hay, which makes it hard to build and hold a good topline.
-
Methionine is a key ingredient in strong hoof wall and healthy coat. It's one of the main things that helps turn good nutrition into visible results you can see in the feet and the shine.
-
Magnesium supports calm focus, steady nerves, and normal muscle function. Horses low on it can seem tense or spooky, so this is one owners often feel the difference from.
-
Zinc is a workhorse for skin, coat, and hoof quality, and it supports a healthy immune system. Most hay is short on it, which is why so many horses need it added.
-
Copper brings out rich coat color and works with zinc to build strong hooves and healthy connective tissue. A faded, washed-out coat is often a sign a horse is short on it.
-
Vitamin E protects muscles and nerves and keeps your horse feeling strong. Horses that don't graze on fresh grass are almost always low on it, so it's one of the most important things to add back.
-
Selenium teams up with vitamin E to protect muscle and support recovery. We use a form that absorbs well and stays in a safe range, dosed carefully so you don't have to worry about overdoing it.
-
Biotin is the ingredient best known for growing stronger, healthier hooves. Paired with the zinc and methionine in this formula, it helps build hoof wall that holds a shoe and resists cracks.
-
Choline supports healthy metabolism, liver function, and steady energy. It's the kind of behind-the-scenes nutrient that keeps everything running the way it should.
-
Live yeast probiotics and digestive enzymes support the good bacteria in your horse's gut. That means better digestion, steadier appetite, and more nutrition pulled from the hay you already feed.
-
A complete set of daily B vitamins for energy, healthy blood, and a strong nervous system, the same kind of full lineup you'd want in your own multivitamin. Most horse supplements skip these or include only one or two.

Built for our horses, backed by our data.
Mane Metrics started as a horse hair testing lab. Before we ever made a supplement, we tested hundreds of horses and kept seeing the same gaps show up again and again, even in horses that looked perfectly healthy.
Foundation Formula is our answer to what we saw. We built it to cover the gaps that are common in nearly every horse's diet, so you can feed it with confidence.
