Everything.

The Science · The Library  ·  By Sara Kirkwood, Founder of Improve Equine  ·  June 2026 “Natural” and “proven” are not the same word, and neither are “a plant” and “a drug.” Before we ever get to which herbs do what in a horse, it’s worth slowing down on what these words actually mean — […]

The supplement aisle is one of the least regulated places a horse owner spends money. Here are the seven questions I run before I trust a product — study, dose, form, survival, ceiling, mechanism, and population.

The Science · The Library  ·  By Sara Kirkwood, Founder of Improve Equine  ·  June 2026 A horse loses minerals in a very specific pattern when it sweats and most of what we reach for to replace them may be solving a problem the horse didn’t have — or worse, creating one. So let’s start […]

Follow the Money: What the Horse World Pays to Learn The Science · The Library  ·  By Sara Kirkwood, Founder of Improve Equine  ·  June 2026 I went looking for proof that a more varied diet builds a more resilient horse. What I found instead was a map of who pays for equine science — […]

By Sara Kirkwood, Founder of Improve Equine · June 2026 — Choke gets treated as a feeding-management problem. But it's really a saliva problem — and the things that prevent it are dentition, feed that makes a horse chew instead of bolt, and hydration.

Written by Sara Kirkwood in The Science The maintenance baseline and the three things that cover it before you consider additional supplementation. Most horse owners walk out of a feed store feeling like they’re underdoing it. The aisles are long, the marketing is confident, the labels are dense, and the implicit message is that figuring […]

Refusing food because it smells wrong is not stubbornness. It is an evolutionary safety latch — and the fix is almost never a new supplement.

Docosahexaenoic acid (DHA) is a long-chain omega-3 polyunsaturated fatty acid found in highest concentrations in marine algae — the original biosynthetic source from which all dietary DHA ultimately derives. DHA and its downstream metabolites play a central role in resolving inflammation, modulating mast cell activity, and supporting immune regulation in both horses and other mammals. […]

Ascorbyl palmitate is the fat-soluble (lipophilic) ester form of Vitamin C. Unlike standard ascorbic acid — which is water-soluble and clears from the body relatively quickly — ascorbyl palmitate integrates into lipid membranes and fatty tissues, providing extended antioxidant protection at the cellular level. This distinction matters for immune function, tissue defense, and the specific […]

Bromelain is a proteolytic enzyme complex extracted from pineapple (Ananas comosus) stem. Beyond its own significant anti-inflammatory properties, bromelain plays a critical synergistic role with quercetin — enhancing its bioavailability and potentiating its effects at the site of action. This combination has been validated in peer-reviewed research on the mechanisms of flavonoid absorption and immune […]

Not all MSM is the same. The method by which methylsulfonylmethane is produced has a profound impact on its purity, contaminant profile, bioavailability, and stability. OptiMSM® (manufactured by Bergstrom Nutrition) is the only MSM produced in the United States using a multi-stage distillation process — a fundamentally different and superior manufacturing approach compared to the […]

Methylsulfonylmethane (MSM) is an organosulfur compound that serves as a bioavailable source of dietary sulfur — an essential element in collagen synthesis, glutathione production, and inflammatory pathway regulation. MSM has been extensively studied for its anti-inflammatory, antioxidant, and immunomodulatory properties, with applications particularly relevant to equine joint health, respiratory inflammation (heaves/equine asthma), and hypersensitivity skin […]

Quercetin is a powerful anti-allergic and anti-inflammatory flavonoid, but it faces a significant limitation: poor oral bioavailability. In its aglycone (free) form, quercetin is only approximately 4% bioavailable after oral administration. Isoquercetin (quercetin-3-O-glucoside, also called isoquercitrin) is a naturally occurring glycoside form of quercetin that is absorbed more rapidly and at significantly higher levels — […]

Quercetin is a naturally occurring flavonoid found in many plants. It is one of the most extensively studied natural compounds for its ability to inhibit mast cell degranulation — the process that releases histamine and other pro-inflammatory cytokines responsible for allergic symptoms. Research consistently shows quercetin outperforms pharmaceutical mast cell stabilizers in human cell studies. […]

Spirulina (Arthrospira platensis) is a blue-green microalgae with well-documented anti-inflammatory properties. Research demonstrates that spirulina directly inhibits mast cell degranulation — the process by which mast cells release histamine and other inflammatory mediators that drive allergic reactions. Key Research Inhibitory Effect on Mast Cell-Mediated Immediate-Type Allergic Reactions Kim HM, Lee EH, Cho HH, Moon YH. […]

Opinion · The Library  ·  By Sara Kirkwood, Founder of Improve Equine  ·  July 2026 Last week I asked what’s stopping you. A reader pushed back with a true and honest take on consequences that was worth it’s own thoughtful response. A response that made me think Last Friday I asked what’s stopping you from […]

By Sara Kirkwood, Founder of Improve Equine  ·  July 2026 There’s the moment you decide to do something better — and then there’s actually doing it, again and again, until it’s just how you do things. These are the areas of friction that prevent me from taking the actions. The seed For me, a change […]

Opinion · The Library  ·  By Sara Kirkwood, Founder of Improve Equine  ·  July 2026 Horses have long been viewed as livestock. So everything we invest in them tends to arrive with a question attached: yeah, but what does it do? The question we attach to horses When people find out I have horses they […]

I yell in the barn sometimes, and I carry a lot of shame about it. But my horses don't perceive it the way I do — and the real work isn't to never have a human moment. It's the untangling: keeping what's good, looking honestly at what isn't, and stopping the habit of treating my own humanness as the thing that has to be trained out of me.

Opinion · The Library  ·  By Sara Kirkwood, Founder of Improve Equine  ·  June 2026 We all agree our horses need a hydration strategy. The question is what you can do with what you have, in the time you’ve got — and why doing some of it always beats waiting until you can do all […]

Opinion · The Library  ·  By Sara Kirkwood, Founder of Improve Equine  ·  June 2026 I just love horses. When I was a kid playing with my Breyers, I didn’t put tack on them or make my Barbies ride them. I took them outside, set them up as a herd, and had them run around […]

Opinion · The Library  ·  By Sara Kirkwood, Founder of Improve Equine  ·  June 2026 I’ve tried being busy, distracting myself, even just checking out and being gone, but it cannot be outrun and this is how, through trial, error and practice, I’ve learned to move through grief. As a child I was described as […]

This past Tuesday, we humanely euthanized Ruthie. A horse person's honest, practical look at planning a good death — the decision, the logistics, the science, and the law — so you're not learning it in the worst hour.

Opinion · The Library  ·  By Sara Kirkwood, Founder of Improve Equine  ·  May 2026 Foundations cover what a horse needs. Optimization is what happens when you decide to do better than the floor — and the only way to do that is to control your levers independently. For the past two weeks, we’ve been […]

By Sara Kirkwood, Founder of Improve Equine · May 2026 — In the horse industry, we have a psychological blind spot: we equate price tags with value. The $1,000 hock injection must be where the result comes from. Meanwhile, water comes out of a tap, so we treat it as ambient. But hydration is the upstream input that decides whether every other investment we make actually works.

By Sara Kirkwood, Founder of Improve Equine · May 2026 — Years before I knew anything about horse welfare science, I was running an agency experiment on humans. I just didn't know that's what it was. The story of how four years in a network test center taught me what every horse owner needs to know about choice, hydration, and the welfare science behind the Water Buffet.

The science on early training of young horses is clear — and it's not up for cherry-picking. A look at bone modeling, confinement, and the three honest paths forward.

Feed manufacturers designed for humans, not horses. Why dietary monoculture causes flavor burnout — and the peer-reviewed science of sensory-specific satiety.

In the largely unregulated world of horse supplements, "proprietary" is a wall between a brand and the consumer. Here's why I'm not building that wall — and why the standard is the standard.

The standard play for a horse that won't drink is salt and electrolytes — hack their biology into thirst and hope they drink enough. Here's why that loop has a flaw, and what desire-based hydration does differently.

I decided to do something a little radical. I'm putting it all on the table — every ingredient, every dosage, every study. No gatekeeping, no mystery. Just the facts.

Getting a horse to take unpalatable medication is one of the most frustrating daily battles in horse ownership. Here's why most masking strategies fail — and what actually works long-term.

Florida horses need significantly more water than horses in temperate climates — and Florida well water creates its own set of challenges. Here's what I learned after moving my herd to Land O' Lakes.

The Water Buffet method isn't a product — it's an approach. Give your horse options, watch what they choose, and let their body tell you what it needs. Here's how to run one.

Cushing's, IR, and laminitic horses need consistent hydration — but most electrolytes and water palatants are the wrong tools for them. Here's what we built instead, and why it matters.

Your horse drinks fine at home. The moment you haul to a show, they stop. Here's the science behind why — and the specific protocol that fixes it.
