Reining horse executing a sliding stop in a show arena, calm and focused under rider
A horse that spooks at shadows, jigs at the trailer, or melts down in a busy warm-up pen is not being bad. He is being overwhelmed. Performance Equine Nutrition was built around that single insight: behavior is often nutrition, and a busy, fearful mind is frequently a mineral-depleted one. The company formulates calming and magnesium supplements for nervous, spooky, unsettled, or irritable horses, with a stated mission to balance horses both mentally and physically, one horse at a time.

Why is my horse so nervous and spooky?
Magnesium drives more than 300 biochemical reactions and is vital to nerve and muscle function, yet performance horses burn through it under the stress of hauling, hard work, and showing. A depleted horse runs hot: skin sensitivity, chronically sore backs, hard muscles, muscle tremors, head shaking, and a mind that cannot settle. Performance Equine Nutrition's MagRestore rebuilds that reserve using di-magnesium malate, a patented form in which one molecule of malic acid binds two molecules of magnesium for superior bio-availability. Because malate does not react with gastric acids, it delivers magnesium to the nervous system without upsetting the gut, which is why it is a frequent companion for horses managed on omeprazole.

What calms a busy-minded competition horse without dulling him?
Focus Equine
is the company's competitor's choice for calming. It pairs magnesium with L-tryptophan, B-vitamins, and a Neuro-Support System of amino acids, including glycine, taurine, L-tyrosine, and inositol, to modulate the neurotransmitters tied to stress responses. The result is a horse that stays calm and trainable while keeping the energy it needs to perform, rather than one that is simply sedated. Mix one scoop daily into feed, starting about seven days ahead of a major event and continuing through the competition window. For horses that need both the mental and the physical side addressed, Focus and MagRestore are offered together as a combo, because Focus quiets a busy, fearful mind while MagRestore replenishes the magnesium behind the physical symptoms.

Performance Equine Nutrition (PEN) is a California-based, direct-to-consumer supplement company operating under the tagline "Where nutrition meets training®" with the stated mission to "balance horses both mentally and physically: one horse at a time." The company is based at 985 Eastman Lane, Petaluma, CA 94952-3622, and can be reached at (707) 766-8624. Rather than selling through feed stores or catalogs, PEN ships therapeutic-grade formulations straight to riders, which is how it keeps USP-grade compounds in the bag at a working-rider price.
Focus Equine calming supplement for performance horses by Performance Equine NutritionWhat is MagRestore® and why di-magnesium malate instead of cheap magnesium oxide? MagRestore® is PEN's flagship equine magnesium supplement, built on di-magnesium malate, a patented form that binds two magnesium molecules to one molecule of malic acid and delivers 2 grams of elemental magnesium per serving. The pelleted version runs 13% magnesium and the powder up to 20.38%, and PEN positions this form for superior bioavailability without the laxative, loose-manure effect riders see from oxide-based products. It comes as pellets (45 servings $33.00, 135 servings $90.00, 450 servings $275.00, 1550 servings $900.00) or powder (45 servings $25.00, 135 servings $70.00, 450 servings $200.00), with Subscribe & Save taking 5% off.
Flex EZ Equine joint supplement with glucosamine by Performance Equine NutritionHow do you actually feed it, and how fast should you see a change? For a 1,000-lb horse, each scoop equals 0.52 oz. The loading or performance dose is 2 scoops AM and 2 scoops PM for ten days (larger horses can go to 3 scoops AM and PM), then horses in light work drop to 1 scoop AM and 1 scoop PM while horses in steady work hold the loading dose. PEN's "Magnesium 101" guidance says deficient horses typically improve within ten days, and points to behavior clues like persistently tight or sore backs, the inability to truly relax, hypersensitivity to grooming along the spine, resistance to blankets, muscle tremors, and the need for long lunging before a horse can focus. The pelleted formula carries no artificial colors, flavors, or preservatives and is built on rice bran, lecithin, ground flax, wheat bran, brewers yeast, and dried molasses flavoring.
Focus and MagRestore combo pack by Performance Equine NutritionWhat about the calming blend, Focus Equine? Focus Equine is PEN's "Competitor's Choice" calming supplement, built around a proprietary Neuro-Support System of USP-grade nutrients including di-magnesium malate, magnesium oxide, taurine, thiamine, glycine, betaine, L-leucine, L-valine, L-alanine, inositol, and L-tyrosine, finished with a natural peppermint sweetener. The intent is to take the edge off a busy, noise-sensitive, or "hot" mind without dulling the horse, by modulating the neurotransmitters tied to stress. The feeding plan is one scoop in daily feed starting seven days before a major event and continued through the competition, with sizes at 7 servings $30.00, 30 servings $105.00, 60 servings $195.00, and 90 servings $285.00. PEN backs it with a money-back guarantee if you see no noticeable improvement within seven days.
What else is in the PEN catalog beyond calming?
The line extends past behavior into soundness and recovery. Flex EZ Equine is a veterinarian-formulated joint supplement delivering 11,000 mg of glucosamine per serving from USP-grade ingredients, fed at 1 scoop (1 oz) daily for light use up to 2-3 scoops for horses in intense work or rehab, priced from $70.00. There is also a Focus / MagRestore Combo (from $52.25), MSM with Aloe Vera (from $34.99), and a family of topical magnesium products, including MagBath ($33.00), MagneSoothe Magnesium Oil (from $10.95), MagneSport Roll On ($13.95), and Mg12 balms (from $14.95), which PEN describes as the most efficient route for raising magnesium levels transdermally.

Supplements for nervous, spooky, unsettled, or irritable horses that combine calming support with nutrition. The core line includes MagRestore magnesium, Focus Equine calming supplement, the Focus and MagRestore combo, and Flex EZ Equine for joint health, plus topical magnesium products such as magnesium oils and balms.
What is in MagRestore and why magnesium?
The active ingredient is magnesium as di-magnesium malate, with each serving supplying 2 grams of elemental magnesium. Magnesium is essential to nerve and muscle function and to over 300 reactions in the body. The pelleted version blends the magnesium with rice bran, lecithin, ground flax, wheat bran, and brewers yeast, with no artificial colors, flavors, or preservatives.
How is MagRestore fed?
For performance horses, a loading dose of two scoops in the morning and two at night is given for about 10 days, or until signs of deficiency ease, with larger horses going up to three scoops twice daily. Maintenance for light work is one scoop morning and night. Each scoop is roughly 10 grams and delivers 2 grams of elemental magnesium for a 1,000 lb horse.
What is in Focus Equine?
Focus Equine uses USP-grade amino acids and botanicals in a Neuro-Support System that includes magnesium, L-tryptophan, B-vitamins such as thiamine, and amino acids including glycine, L-valine, L-alanine, L-tyrosine, taurine, and inositol, sweetened with natural peppermint. It is built to reduce nervous energy and support mental stability while maintaining alertness.
How and when do I feed Focus Equine?
Mix one scoop daily into feed. The company recommends starting about seven days before a major event and continuing through the competition period, and notes it is useful before workouts, trailering, vet visits, and arena schooling, as well as during rehab.
Which horses is this for?
Busy-minded or hot horses, nervous and easily distracted mounts, and horses that are sensitive to noise or new environments. The supplements are aimed at horses whose nervous, spooky, or irritable behavior gets in the way of training and competing.
Should I use Focus, MagRestore, or both?
It depends on what you are seeing. MagRestore addresses the physical signs of magnesium depletion such as muscle tension, sore backs, and twitching, while Focus Equine targets the mental side, quieting a busy, fearful mind and reducing adrenaline release. Horses that show both are often served by the Focus and MagRestore combo, and the company offers complimentary one-on-one consultations to match products to the individual horse.
How does Performance Equine Nutrition keep quality high?
The company emphasizes USP-grade compounds rather than cheaper animal-grade nutrients, and sells directly to customers without middlemen so it can maintain that quality at an accessible price. Its products carry no artificial colors, flavors, or preservatives.
What is MagRestore® and what makes it different from other equine magnesium supplements?
MagRestore® is Performance Equine Nutrition's magnesium supplement built on di-magnesium malate, a patented form that binds two magnesium molecules to one molecule of malic acid and delivers 2 grams of elemental magnesium per serving. The company positions this form for high bioavailability without the loose-manure laxative effect commonly seen with magnesium oxide products. It is sold in pelleted (13% magnesium) and powdered (up to 20.38% magnesium) versions.
How much MagRestore® do I feed my horse?
For a 1,000-lb horse, each scoop equals 0.52 oz. The loading or performance dose is 2 scoops in the morning and 2 scoops in the evening for ten days, and larger horses can increase to 3 scoops AM and PM. After loading, horses in light work drop to 1 scoop AM and 1 scoop PM, while horses in steady work maintain the loading dose.
How much does MagRestore® cost?
The pelleted version is priced at $33.00 for 45 servings (a ten-day trial), $90.00 for 135 servings (30 days), $275.00 for 450 servings, and $900.00 for 1550 servings. The powder is $25.00 for 45 servings, $70.00 for 135 servings, and $200.00 for 450 servings. A Subscribe & Save option takes 5% off across all sizes.
What is Focus Equine and how is it different from MagRestore®?
Focus Equine is Performance Equine Nutrition's calming supplement, marketed as the Competitor's Choice. Where MagRestore® is a daily magnesium-restoration product, Focus Equine is a proprietary Neuro-Support System blend of magnesium plus amino acids and nutrients designed to take the edge off a busy or stressed mind, especially around competition. Many riders use them together via the Focus / MagRestore Combo.
How do I use Focus Equine for a show or competition?
Mix one scoop of Focus Equine into the daily feed, starting seven days before a major event and continuing through the competition period. It is also used situationally for trailering, vet visits, and arena schooling. Performance Equine Nutrition recommends consulting your veterinarian for personalized guidance, and offers a money-back guarantee if you see no noticeable improvement within seven days.

What are the signs my horse may be magnesium deficient?
Performance Equine Nutrition's Magnesium 101 resource lists indicators such as persistently tight or sore backs unrelated to saddle fit, an inability to truly relax, sensitivity during grooming along the spine, resistance to blankets, a history of tying-up, unexplained muscle tremors, needing long lunging before the horse can focus, bucking shortly after exercise begins, hypersensitivity to touch, difficulty engaging the hindquarters, and compulsive behaviors like weaving or pacing. Stress hormones, hard work, sweat, diuretics, and over-supplementing calcium or sodium can all deplete magnesium.
Will MagRestore® cause loose manure or diarrhea?
Performance Equine Nutrition specifically formulated MagRestore® with di-magnesium malate to avoid the laxative effect linked to magnesium oxide. Loose manure is listed as a possible side effect but is typically resolved by adjusting the dosage. Horses with renal insufficiency should be monitored, and the product should be separated from omeprazole, slippery elm, ulcer products, and gut-health supplements.
Can I give MagRestore® to a horse on ulcer medication like omeprazole?
Yes, MagRestore® is even targeted at horses on omeprazole, but the company advises separating the magnesium dose from omeprazole, slippery elm, and other ulcer or gut-health supplements rather than feeding them at the same time. As always, consult your veterinarian for horses on medication.
What is Flex EZ Equine and who is it for?
Flex EZ Equine is Performance Equine Nutrition's veterinarian-formulated joint supplement, delivering 11,000 mg of glucosamine per serving from USP-grade ingredients. It is designed to support joint integrity, reduce inflammation, and promote long-term soundness in horses facing the wear and tear of training and competition. It is priced from $70.00.
How do I feed Flex EZ Equine?
For a 1,000-lb horse, each scoop is 1 ounce and delivers a full dose. Light use is 1 scoop daily top-dressed on feed; moderate use is 1 to 2 scoops daily for horses in light training or older horses; and heavy use is 2 to 3 scoops daily for horses in intense training, competition, or rehabilitation.
What other products does Performance Equine Nutrition sell?
Beyond MagRestore®, Focus Equine, and Flex EZ Equine, the catalog includes MSM with Aloe Vera (from $34.99), the Focus / MagRestore Combo (from $52.25), and a range of topical magnesium products such as MagBath ($33.00), MagneSoothe Magnesium Oil (from $10.95), MagneSport Roll On ($13.95), and Mg12 balms (from $14.95). They also carry Kombat Boots and branded merchandise like caps, mugs, and water bottles.
Why does Performance Equine Nutrition use USP-grade ingredients?
The company exclusively uses USP-grade compounds rather than animal stock-grade ingredients, which it says yields therapeutic-grade formulations not available in feed stores or catalogs. The argument is that higher-purity, more bioavailable ingredients are ones the horse's body can actually absorb and use, producing more reliable results.
Is topical magnesium effective for horses, and what products are offered?
Performance Equine Nutrition presents transdermal application as one of the most efficient ways to raise a horse's magnesium levels, noting that smaller, frequent doses enhance bioavailability. Topical options include MagBath for soaking, MagneSoothe Magnesium Oil, the MagneSport Roll On for targeted areas, and Mg12 body and MagneSport balms.
How do I buy from Performance Equine Nutrition, and is there a guarantee?
