Not just Vitamin E. A complete delivery system.
Cellular support for muscle, nerve, recovery, and capacity. Natural Vitamin E + functional fat delivery system.
ScoopRx uses a whole-food fat base to deliver natural Vitamin E into a more functional cellular environment — where recovery, nerve signaling, stress response, and regulation are happening. Because what matters isn't just how much goes in. It's how much the horse can actually use.

The form matters. The delivery system matters.
Fresh green pasture is the horse's natural source of Vitamin E. Once forage is cut and dried, Vitamin E begins to decline. Many modern horses live on hay-based diets for part or all of the year — receiving less Vitamin E than they would from fresh pasture.
And here's the part that surprises most people: UC Davis / Finno Laboratory research found that 35.5% of horses already receiving Vitamin E supplementation remained below optimal serum levels.
Not unsupplemented horses. Horses whose owners were already doing the right thing. The problem isn't effort — it's often form, delivery, and utilization.
Synthetic Vitamin E is a mixture of eight molecular forms. Only one is the natural RRR form the horse's body retains and uses preferentially. Natural Vitamin E provides the RRR form directly.
"The difference isn't the IU number. It's the form, the fat, and the biology behind it."
Two layers, not one. Built around the matrix.
Most equine Vitamin E products focus on alpha-tocopherol alone. Stacked Fat+E goes further — delivering a natural Vitamin E complex containing both tocopherols and tocotrienols, layered into a functional fat matrix designed for absorption and utilization.
Tocopherols — the established foundation
Tocopherols provide the core Vitamin E foundation: antioxidant protection, muscle support, normal neuromuscular function, cell membrane protection, and Vitamin E status support. This is the Vitamin E language horse owners already understand — but it's not the whole story.
Tocotrienols — the membrane-active layer
Tocotrienols are structurally different from tocopherols, with a more flexible, mobile character inside lipid-rich membranes. That matters because muscle cells, nerve cells, and mitochondrial membranes are all lipid-rich — the places where energy is produced, stress accumulates, and recovery begins.
Functional fat matrix — 39.2% minimum
Vitamin E is fat-soluble. Stacked Fat+E is built around a five-source functional fat matrix — rice bran, coconut, flax, sunflower, safflower — plus digestive enzymes and pre/probiotic support. No sugar carrier. No synthetic Vitamin E. No fillers. A tight horse is not always just a muscle story. Tension lives in the conversation between the nervous system, the muscle, and the body's ability to recover from cellular stress. Tocotrienols add a membrane-active antioxidant layer that supports the cellular environment where stress, recovery, nerve signaling, and regulation are happening.
The science behind the formula.

per scoop — the same dose used in the Fagan University of Georgia study, where natural Vitamin E outperformed synthetic at the same dose.
In the 2020 University of Georgia Fagan study, horses receiving 4,000 IU/day of natural RRR-alpha-tocopherol showed higher serum Vitamin E, lower oxidative-stress markers CSF Saturation, lower AST after exercise, and less reduction in stride duration compared with synthetic Vitamin E groups — including the synthetic group fed the same 4,000 IU/day dose.AST Reduction
Tocotrienol research adds a mechanistic layer: their structurally different tail gives them a more mobile character inside lipid-rich membranes, where they're being studied for antioxidant, mitochondrial, inflammatory-signaling, and neuroprotective effects.12-LOX Block
Stacked Fat+E is research-informed and biologically intentional — built around published equine Vitamin E science, veterinary guidance, and formulation logic.
You have done the training. You have done the bodywork. The saddle fits. The program is thoughtful. And still, something feels guarded. The back does not fully release. The body stays braced. The horse tries, but cannot quite get there.
Sometimes nutrition is part of that picture. Oxidative stress, mitochondrial load, recovery demand, and nerve-muscle communication can all influence how available a horse feels in their body.
The horse isn't resistant. The system is overloaded.
- Hauling, competition, and hard training trigger a surge in oxidative load across muscle tissue, nerve cells, and the mitochondria generating energy for every stride. When that load exceeds the body's antioxidant capacity, the horse compensates.
- Tension. Slow recovery. Reactivity. Flatness. These aren't personality. They're biology. The horse is not broken — the system is carrying more than it should, including unchecked nitrogen radicals that create background nervous-system irritation.
- Stacked Fat+E supports the cellular environment where that stress is actually happening — not by taking the edge off, but by reducing the load the body is trying to compensate for.
For the horse being asked to do more.
For the horse in work. For the horse under stress. For the horse who is traveling, aging, training, or carrying more internal load than they show on the surface. For the horse who needs more than a basic powder in a bucket.
- Performance horses in heavy training, travel, or competition
- Horses on hay-based diets with limited pasture access
- Older horses needing increased antioxidant support
- PPID-managed, insulin-sensitive, or metabolic-sensitive horses (as part of a vet- or nutritionist-guided program)
- Any horse already supplementing Vitamin E whose owner wants a more complete form-and-delivery system
"A horse that softens after nutritional support wasn't anxious. They were overloaded. Remove the load. Support the system. The horse finds their own balance."
Ten weeks. One horse. What changed when the load was removed.
Mango was carrying oxidative stress in muscle tissue, hindgut inflammation, and hormonal dysregulation. On paper, she was managed. On the ground, she was guarded. Her in-gate person gave the judge a heads-up before every class — out of habit, out of necessity.
That behavior had a biology underneath it. Over ten weeks of targeted nutritional support — with Stacked Fat+E supporting the cellular environment where her stress was happening — the picture changed.
Oxidative load cleared. Gut inflammation reduced. Hormonal system supported. The internal noise that was driving her behavioral patterns went quiet. In week ten, Mango walked into the ring. No heads-up to the judge. No bracing at the gate.
The behavior hadn't been trained out of her. It had no reason to exist anymore.
"The stride opens when the body stops compensating. It did."
Flexible dosing for what your horse actually needs.
Each scoop provides 4,000 IU of natural Vitamin E. Adjust based on individual need, workload, age, diet, and veterinary or nutrition guidance.
| Goal | Daily Amount | Vitamin E |
|---|---|---|
| Baseline Support | 1/4 scoop | 1,000 IU |
| Maintenance | 1/2 scoop | 2,000 IU |
| Performance Support | 1 scoop | 4,000 IU |
For horses with known Vitamin E deficiency, neurological symptoms, muscle disease, PPID, insulin dysregulation, laminitis history, or other medical concerns, supplementation should be guided by a veterinarian and bloodwork.
Add-on to Athlete or Master — does not replace the daily scoop.
Most products sell an IU number. Stacked Fat+E delivers a system.
