Red and near-infrared light therapy is a non-invasive tool commonly used to support circulation, comfort, recovery, and long-term wellness in horses. ReGen Equine systems are designed for horses at every stage of life and may also be used for dogs and humans.

​

This page provides foundational information about equine red light therapy — what it is, how it works, and how it is generally applied. More detailed guidance on wavelengths, usage, and condition-specific support is available through the resources linked below.

At a Glance

• Non-invasive red and near-infrared light therapy
• Commonly used to support circulation, comfort, and recovery
• Applied for daily maintenance, post-work recovery, and ongoing support
• Utilizes clinically relevant wavelengths selected for equine anatomy
• Consistency over time is typically more important than longer individual sessions

​

What Is Red Light Therapy for Horses?

Red light therapy, also known as photobiomodulation, uses specific wavelengths of visible red and near-infrared light to interact with tissue. These wavelengths are absorbed by cellular photoreceptors and are commonly used to support normal cellular function, circulation, and tissue comfort.

In horses, red light therapy is used as a supportive tool and is most often incorporated alongside proper training, veterinary care, farrier work, and rehabilitation programs.

​

How Red Light Therapy Works in Horses

When red or near-infrared light is applied to tissue, light energy is absorbed by structures within the cell — primarily within the mitochondria. This interaction is associated with changes in cellular energy availability and circulation.

Because horses have dense muscle, connective tissue, and large joints, wavelength selection and output matter. Equine-specific systems are designed to account for tissue depth, coat thickness, and anatomical scale.

​

Why Wavelength Choice Matters

Different wavelengths of light interact with tissue at different depths. Using more than one wavelength allows support across multiple tissue layers rather than focusing on the surface alone.

ReGen Equine systems use a multi-wavelength approach designed specifically for equine anatomy, rather than relying on a single light output.

​

​

Understanding ReGen’s Wavelength Approach

ReGen Equine systems utilize three clinically relevant wavelengths selected for general therapeutic application in horses:

660nm (Red Light)
Commonly associated with surface-level tissue, skin, and superficial circulation.

850nm (Near-Infrared)
Commonly used for muscle, tendon, ligament, and connective tissue support.

940nm (Infrared)
Often included where deeper tissue interaction, circulation support, or dense structures are involved.

​

These wavelengths are used together as part of ReGen Equine’s Tri-Wave Light System™, allowing for layered tissue interaction rather than isolated depth targeting.

​

How Red Light Therapy Is Commonly Used

Red light therapy is commonly incorporated into equine care routines for:

• Daily maintenance and comfort
• Post-exercise recovery
• Long-term wellness support
• Structured rehabilitation programs

Application methods, frequency, and session length vary based on the individual horse, the area being supported, and the overall care plan.

​

​

Safety, Expectations & Consistency

Red light therapy is non-invasive and widely used as a supportive modality when applied appropriately.

General best-practice principles include:

• Starting with shorter sessions and increasing gradually

• Allowing time between sessions on the same area

• Avoiding direct exposure to the eyes

• Monitoring comfort and response during use

Responses vary between horses. Some may show visible relaxation quickly, while others benefit most from consistent use over time.

Red light therapy is not intended to replace veterinary diagnosis or treatment and is most commonly used as part of a broader care approach.

​

​

Essential Series vs Pro Series (High-Level Overview)

ReGen Equine offers two product lines built around the same core light therapy principles:

​

Essential Series
Designed for reliable daily use, maintenance, and general recovery support.

​

Pro Series
Designed for higher workloads, structured programs, and situations where greater output or coverage is preferred.

​

Selection typically depends on routine structure, frequency of use, and intensity of need rather than different therapeutic principles.

​

​

Final Note

Red and near-infrared light therapy is best viewed as a long-term support tool rather than a one-time solution. Thoughtful application, consistency, and integration with proper care practices are key.
