Navicular Problems in Horses: What to Know

First published November 2015 · Revised 2026

Navicular problems are the most common cause of lameness in horses, and they start in a bone most owners have never seen: a small one, tucked behind the coffin bone, doing two big jobs. Here's what it does, what goes wrong, and what helps.

First, the bone itself

A small bone with two big jobs.

The navicular bone sits directly behind the coffin bone, held in place by tendons and ligaments. Small as it is, it matters to the health of the whole hoof, and the whole horse.

Job one
Shock protection

It protects the joint and tendons from the pressure and concussion of every stride.

Job two
Blood-flow valve

It acts as a valve for blood flow to the coffin bone and the corium inside the hoof.

When trouble comes, it usually comes from the ground up: improper trimming of the hoof, short- or long-term shoeing, or an inadequate natural environment.

Symptoms to watch for

Navicular problems tend to worsen when the horse is worked in a circle, especially in activities like lunging, so stumbling can show up at any gait, even a simple walk. It's usually most obvious when the horse is asked to step over obstacles: ground poles, tree roots, rocks.

Your farrier is your first ally here. Regular farrier work keeps navicular issues manageable, and in some cases special shoeing is needed; shoes can add extra support to the foot, ligaments, and structure of the leg.

The nutrition underneath it all

Support for the structures doing the work.

The Nzymes Sprouted Granules are a super-food protein supplement that supports the musculoskeletal side of a comeback: bones, muscles, tissues, skin, and hair. The live sprouted food delivers resources that enhance the body's own natural enzyme activity and help it produce its own supporting antioxidants. Because of this, they may ease inflammation and support healthier bone density. That cellular-level activity supports the metabolic processes that reduce toxic and free-radical damage, and every joint and muscle structure in the body benefits from that work, the navicular area included.

Questions horse owners ask
What is the navicular bone, and what does it do?

A small bone located directly behind the coffin bone, held in place by tendons and ligaments. It has two main jobs: protecting the joint and tendons from pressure and concussion, and acting as a valve for blood flow to the coffin bone and corium in the hoof.

What are the signs of navicular trouble?

A short, choppy stride with lameness, toe-first gaits (tippy-toeing), shifting weight from foot to foot, and soreness after working. Problems often show more when the horse works in a circle, as in lunging, or steps over obstacles like ground poles, roots, or rocks.

What causes navicular problems?

Common contributors include improper trimming of the hoof, short- or long-term shoeing, and an inadequate natural environment.

Can farrier work really help?

Yes. Regular farrier work keeps navicular issues manageable, and in some cases special shoeing is needed: shoes can add extra support to the foot, ligaments, and structure of the leg.

How do the Sprouted Granules support the navicular area?
