At the cellular level

How photobiomodulation works at the cellular level

This is how research describes the mechanism: red light (660 nm) and near-infrared (810 nm) penetrate the tissue and reach the mitochondria — the "powerhouses" of the cell. This is where photobiomodulation (PBM) takes effect.

The mitochondrial hub: cytochrome c oxidase

Red and near-infrared light is absorbed by cytochrome c oxidase (Complex IV) in the inner mitochondrial membrane. This enzyme is the key of the respiratory chain — it catalyses the final stage of the electron transport chain, where oxygen is used to generate energy. It is considered the central light acceptor (chromophore) of PBM.

1 · More ATP — more cellular energy

Activating cytochrome c oxidase strengthens the proton gradient across the mitochondrial membrane. Research associates this with an increased ATP production — more available energy that can support the cell's natural processes.

2 · Less mitochondrial stress

At the same time, a lower formation of reactive oxygen species (ROS / free radicals) is described — which can reduce oxidative stress at the cellular level and support cell regulation.

3 · Cellular signalling pathways

The rise in ATP and the modulation of ROS are considered triggers of cellular signalling cascades associated with cell survival, balanced regulation processes and the body's own regeneration — processes that can support wellbeing.

Not only local — the systemic perspective

Current research describes that PBM doesn't act only on the irradiated tissue: a local application can reach more distant regions via circulating factors released from the irradiated cells — an approach that can support microcirculation broadly.

Why in horses?

Muscle, tendon and cartilage cells have a high mitochondrial density — exactly the target structure of PBM. Red light reaches surface-near structures (approx. 5–10 mm), near-infrared medium depths (up to approx. 20–30 mm) — suitable for skin, coat, muscles, tendons and joints.

Level	Effect described in PBM research
Mitochondrial	ATP ↑ · ROS ↓
Cellular	cell regulation & cell survival supported
Tissue	circulation ↑ · regeneration ↑
Systemic	circulating, regulating factors

Our approach

The right approach instead of raw power

Infrared-focused: more 810 nm

8 of the 14 LEDs are near-infrared. NIR physically has a greater penetration depth than red light — the [B4A] PBM deliberately focuses more on depth than many comparable devices.

Selectable 10 Hz pulse

Continuous light or pulsed at 10 Hz. Pulsed photobiomodulation is an active research field; the choice is yours.

One button. Deliberately simple.

No display, no app: Press — red + infrared on. Hold 3 seconds — 10 Hz pulse. Press again — off. One-hand operation, even with gloves.

LED — not laser

14 high-power LEDs, red and infrared combined. Photobiologically tested to EN 62471, Risk Group 1 — no safety goggles required; do not look directly into the light source.

Areas of use

Three areas – one device

From targeted use in rest phases through the routine after exertion to daily prevention — the [B4A] PBM supports your horse through every phase.

1 · Recovery in rest phases

Targeted at strained regions when a demanding phase is ahead.

Targeted at strained regions

Support for regeneration at tendons, joints and muscles – a few minutes daily, in coordination with your vet.

In rest & rebuilding phases

In low-movement phases, the body's own regeneration can be supported – position by position.

Alongside professional care

As a supportive wellness routine – in coordination with your vet and physio.

2 · Regeneration after exertion

After training, shows and transport: the short routine for muscles, tendons and joints.

Muscles & tension

Can accompany the relaxation of strained muscles — e.g. after training, work or longer rest periods.

Tendons & joints

Can be used supportively around heavily loaded regions such as tendons and joints — as part of the recovery routine.

Shows & transport

Between two starts and after the trailer: planned regeneration for tendons, joints and trunk muscles – the device travels with you.

3 · Prevention & routine

The daily habit that sticks.

Skin & coat

Can be used supportively in the care routine around skin and coat — e.g. at the pastern and coronet.

Seniors

Can support the wellbeing of older or heavily worked horses in daily life — lower joints, back in sections.

The daily short routine

Box, paddock, standing times: the short daily application – short enough to actually happen every day.

Nervous system & recovery

Regeneration starts in the nervous system

The vagus nerve is the main line of the rest-and-digest nervous system (parasympathetic) – and regeneration mainly happens when it is in charge. This is exactly where an exciting, emerging research field begins.

The vagus nerve

As the central nerve of the parasympathetic system, the vagus stands for "rest and recovery". Only when the nervous system switches to rest can the body regenerate. It runs relatively close to the surface at the side of the neck.

What research describes

Current research is investigating whether photobiomodulation may also influence the autonomic nervous system. Individual small studies describe changes in heart rate variability (HRV) – a possible indication of a shift towards relaxation.

An emerging field

Not a settled truth – but exactly the direction that makes recovery so exciting: regeneration begins where the nervous system comes to rest.

Note: Always apply at the neck with a good distance from the eyes.

Included training

The device is the start – the knowledge makes the difference

Recovery, regeneration and prevention only work with the right routine: which position, how long, when recovery and when prevention. That's why every [B4A] PBM includes the matching B4A Academy online course – a dedicated course for your horse.

Step by step on the horse

Guided application position by position – from the leg to the back to the hindquarters.

Recovery vs. prevention

When each routine makes sense – after exertion, in rest phases and as a daily habit.

Safe & correctly dosed

Distance, duration and the selectable 10 Hz pulse mode – used correctly in everyday life.

FAQ

Frequently asked questions about the [B4A] PBM

What is the [B4A] PBM?

A handy battery-powered device for light wellness in horses. It combines red light (660 nm) and near-infrared (810 nm) — for your horse. A wellness product, not a medical device.

Which horses is the [B4A] PBM suitable for?

For horses of any age – from the sport horse to the senior. The included manual describes use on horses. It is a wellness product and not a medical device.

Does my horse need safety goggles?

No. The [B4A] PBM is photobiologically tested to EN 62471 and classified in Risk Group 1 (low risk) — safety goggles are not required. As with any bright light source: do not look directly and deliberately into the LEDs.

What does photobiomodulation (PBM) mean?

PBM describes how light of certain wavelengths is absorbed by cells and triggers biological processes there — above all in the mitochondria, the "powerhouses" of the cell. Red and infrared light are considered the relevant wavelengths for this.

Why 660 nm and 810 nm together?

660 nm acts more on the surface (skin & coat), 810 nm penetrates deeper and reaches muscles, tendons and joints. The [B4A] PBM always emits both wavelengths together, covering surface and depth.

What can I use it for?

As part of your horse's daily recovery and care routine: around muscles, tendons and joints, for regeneration after exertion, on skin & coat and for general relaxation. It can provide supportive care for wellbeing — it is not a medical device and makes no healing claims.

PBM or PEMF — which first?

As a practice-proven recommendation: first PBM, then PEMF. The reason lies in the optics: red and near-infrared light penetrates best into undisturbed tissue. PEMF increases blood flow — more haemoglobin in the tissue absorbs the light and reduces penetration depth. If you use the light first, it uses the full "optical window". Afterwards, PEMF can stimulate circulation over a larger area and distribute the effects in the tissue.

In practice: 1) PBM on the target area, 2) a short pause, 3) PEMF over a larger area afterwards. For very tense or cold tissue, PEMF can also come first as a "warm-up" — both orders are fine.

Note: The combination of PBM + PEMF is an active research field without robust sequence studies. A practice-oriented recommendation, not a proven synergy.

How do I operate the device?

One button: press — red + infrared light up together. Hold for 3 seconds — 10 Hz pulse mode. Press again — off. No display, no app, operable with one hand.

What is the 10 Hz pulse mode for?

You can choose between continuous light and pulsed light at 10 Hz. Pulsed photobiomodulation is an active research field – we deliberately built the mode in so you have the choice, rather than leaving it out.

Is it loud?

No. The [B4A] PBM works without a fan — especially with horses an advantage for acceptance.

How long does an application take?

It depends on the distance. As a rough guide: at contact a few minutes per point, and correspondingly longer at greater distances.

LED or laser?

14 high-power LEDs, red and infrared combined. No laser safety goggles needed; 810 nm is invisible and creates no glare reflex in the horse.

Battery and charging?

10,000 mAh battery (3.7 V / 37 Wh), charging via USB-C. The battery is not permanently sealed but replaceable. The device is screwed shut; the battery swap is handled by our service (please don't open it yourself during the warranty period). So only the battery is replaced, not the whole device.

Is this a medical device?

No. The [B4A] PBM is a wellness product for horses. No medical, therapeutic or healing effects are claimed.
