Reading Horse Supplement Labels: What AAFCO Compliance Actually Tells You

Most equine supplement labels are designed to be admired, not read. Here's how to read one.

If you keep horses, you've probably seen a lot of bottles in your tack room. Big claims on the front, blurry guaranteed-analysis on the back, ingredient lists in a font you have to squint to find. There's a reason for that, and it's not a flattering one.

What AAFCO compliance actually means

AAFCO — the Association of American Feed Control Officials — sets the standards US states use to regulate animal feed and feed supplements. When a label is “AAFCO-compliant,” it means it includes the things AAFCO requires you to disclose, in the format states expect to see them: a product name, a guaranteed analysis with specific nutrient minimums and maximums, an ingredient list, feeding directions, and a statement of purpose.

It doesn't mean the product was tested or approved by AAFCO. AAFCO doesn't approve products. State feed control officials do, and they do it on a state-by-state basis. What AAFCO compliance does mean is that the label is structured in a way regulators can interpret, which is the floor for being able to sell honestly.

What to look for on a horse supplement label

Guaranteed analysis with real numbers

Look for specific values: protein min %, fat min %, fiber max %, plus the nutrients the product is built around. Vague potency claims (“high in minerals”) aren't compliant labeling — they're marketing copy.

A complete ingredient list, in descending order by weight

If the label hides ingredients behind a “proprietary blend,” you can't tell how much of anything is actually in the bottle. That's not illegal, but it tells you what the brand prioritizes.

Feeding directions that match the math

If a bottle is sold for one scoop per day and contains 100 scoops, that's a 100-day supply. If the math doesn't add up, the product won't actually do what the label promises — not because the formula is wrong, but because the operational assumptions are wrong.

A clear purpose statement

What does the product do? AAFCO requires a purpose statement in structure/function language — supports digestive function, supports condition, supports recovery. If the label is making disease claims (“cures,” “treats,” “heals”), the product isn't supposed to be sold as a feed supplement.

What we put on the Equine Intact label

The Equine Intact™ label leads with guaranteed analysis, a complete ingredient list (no proprietary blend), feeding directions that match the 157-day cycle math, and a structure/function purpose statement. You can see it on the product page, or read our broader sourcing & labeling standards.

One last thing

If a horse supplement is selling on adjectives — revolutionary, breakthrough, doctor-formulated — without specific nutrients in specific amounts on the back of the bottle, the adjectives are doing the work the math should be doing.

You earned the right to read a label that respects you. Demand one.

Equine Intact™ is formulated and labeled in accordance with AAFCO guidance for animal feed supplements. This product is not intended to diagnose, treat, cure, or prevent any disease.
