One of the questions we're often asked is, " What actually is Spirulina ?"

Thing is, Spirulina isn't a herb at all. It's a microscopic blue-green algae that evolved billions of years ago and remains one of the most nutrient-dense foods ever discovered. Long before horses, humans, or even trees existed, these remarkable organisms were already helping shape life on Earth.

Billions of years later, they're valued for exactly the same reason.

Spirulina concentrates an extraordinary amount of nutrition into an incredibly small space. Rich in highly digestible protein, chlorophyll, essential fatty acids, antioxidants, vitamins, minerals, and unique pigments such as phycocyanin, it provides the raw materials every cell depends upon to function normally.

That's why Spirulina appears in so many different areas of health, because healthy cells underpin healthy muscles, immunity, metabolism, tissue repair, energy production.

Rather than targeting one body system, Spirulina simply helps nourish the body from the ground up.

But there's another reason we value it so highly at EquiNatural.

Unlike many nutritional superfoods, Spirulina also has a remarkable ability to bind naturally occurring mycotoxins within the digestive tract before they can be absorbed. That makes it particularly useful during forage changes, when feeding haylage, following digestive disturbance, or whenever we want to provide a little extra support for the hindgut.

It's one of the reasons you'll find Spirulina throughout our Gut System range.

• In LeakyGutCOMBO and KPUCOMBO, it helps support the intestinal environment while binding unwanted microbial toxins.
• In PollenCOMBO, it contributes valuable antioxidant and immune-supportive nutrients during the allergy season.
• And in VitaBoost and LymeCARE, it provides concentrated nutritional support whenever the body is working that little bit harder.

In short? Some supplements perform one specific job. Spirulina quietly supports almost every system in the body because every system ultimately depends on healthy, well-nourished cells.

Spirulina is a good fit when you're looking to nourish your horse at the most fundamental level – the cell.

✔ You'd like to add one of nature's most nutrient-dense wholefoods to the daily diet

✔ Your horse is recovering from illness, injury, or a demanding period of work

✔ You'd like to support healthy immunity, muscle recovery, or overall vitality

✔ Haylage, forage quality, or digestive health has you thinking about mycotoxins

✔ You simply want to strengthen your horse's nutritional foundations rather than target one specific problem

In short: if you're looking for a versatile nutritional superfood that quietly supports almost every system in the body, Spirulina is one of the simplest places to start.

From there, support can be adapted depending on what you're seeing.

- Supporting specific systems

• LeakyGutCOMBO – where Spirulina combines with SiboCARE and GutAminos to help support hindgut stability, intestinal health, and bind unwanted microbial toxins.
• KPUCOMBO – where additional nutritional support is needed alongside the gut–liver–nutrient pathways involved in more complex, multi-system patterns.
• PollenCOMBO – where Spirulina contributes valuable antioxidant and nutritional support during periods of seasonal respiratory or pollen challenge.

- Foundation support

Spirulina complements rather than replaces the foundations of a balanced diet. Good-quality forage and a forage-based mineral blend such as VitaComplete or EquiVita provide the wider nutritional framework, while Spirulina adds an exceptionally rich source of natural proteins, pigments, minerals, and phytonutrients.

I*f you're not already feeding a mineral balancer, try one of our 1kg trial bags.

In summary

Use Spirulina as an everyday nutritional foundation that quietly supports the whole horse. Then layer more targeted blends around it depending on whether your focus is gut health, immunity, respiratory wellbeing, recovery, or longer-term metabolic resilience.

This is a nutritional, functional horse food supplement and not veterinary medicine. See Dr Kellon's article - Nutrition is not 'Alternative' Therapy.

Energetic Architecture explains how a nutrient or formula is structured to support the body in a balanced and purposeful way.

Spirulina is unusual because it doesn't focus on one particular system. Instead, it works at the level every system has in common - the cell.

Think of it as strengthening the foundations rather than reinforcing just one room of the house.

Functional intent

Spirulina is designed to support:

• everyday cellular nutrition
• healthy energy production
• natural antioxidant defence
• gut and immune resilience
• nutritional recovery during periods of increased demand

Rather than targeting one problem, Spirulina helps supply many of the raw materials the body relies upon every single day.

Functional categories – support in action

1. Cellular nutrition & protein foundation
   - Providing highly digestible protein, essential amino acids, vitamins, minerals, and chlorophyll to help nourish cells throughout the body.

   - Supplying naturally occurring pigments including phycocyanin, chlorophyll, and carotenoids that help support normal antioxidant defences and healthy cellular metabolism.
3. Gut ecology & mycotoxin binding
   - Helping bind naturally occurring mycotoxins within the digestive tract while supporting a healthier intestinal environment during periods of forage or digestive challenge.
4. Immune & recovery support
   - Providing broad-spectrum nutritional support for the body's natural immune function, tissue renewal, and recovery following periods of physical or environmental demand.

Big picture

Here's what I find most fascinating about Spirulina - people often ask which body system it supports, but the honest answer is... almost all of them.

Not because Spirulina somehow has a separate job for every organ, but because every organ is built from healthy cells.

When you nourish the cell well, you're quietly supporting everything that depends upon it.

It's one of the reasons this tiny blue-green algae has earned such a remarkable reputation - it's simply giving the whole body better building materials.

Spirulina is generally considered a highly safe, nutrient-dense superfood when sourced responsibly and used within the recommended feed rate. However, a few caveats apply:

• Protein Sensitivity – Due to its high protein content (up to 65%), spirulina may not be suitable for horses with compromised kidney function. Always consult with your vet if in doubt.
• Autoimmune Conditions – Spirulina’s potent immune-modulating effects are usually a plus, but in rare cases, excessive intake may overstimulate the immune system in individuals with existing autoimmune conditions.
• Contamination Risk – Not all spirulina is created equal. Poorly sourced spirulina (especially wild-harvested from uncontrolled lakes) can contain heavy metals or I, which are toxic. We only use Organic Certified clean, cultivated spirulina from trusted sources - tested for heavy metals, microcystins, and other environmental contaminants.

The tiny organism that changed the world

Spirulina isn't a herb. In fact, it isn't even a plant.

It's a microscopic blue-green organism that was quietly living on Earth around three and a half billion years ago - long before there were humans, forests... or even horses.

And here's the truly extraordinary part.

Scientists believe ancient ancestors of Spirulina helped produce much of the oxygen that transformed Earth's atmosphere, making it possible for more complex life to evolve.

Which means, in a very real sense, we're all here because tiny organisms rather like Spirulina got to work billions of years before anything else.

Not bad for something you can fit on the end of a teaspoon.

Ancient food, long before it became a superfood

Although Spirulina has only become fashionable in recent decades, people have been eating it for far longer than most realise.

The Aztecs harvested it from Lake Texcoco, where it was dried into nutrient-rich cakes that became an important everyday food.

Thousands of miles away, the Kanembu people around Lake Chad independently developed almost exactly the same idea, harvesting Spirulina from alkaline lakes and drying it into traditional cakes called dihe that remain part of local diets today.

I always find this sort of thing fascinating - different cultures, different continents, no communication between them, yet both recognised that this tiny blue-green organism was worth collecting and eating.

That usually tells us something.

What people noticed before laboratories did

Long before anyone measured protein percentages or discovered pigments like phycocyanin, people simply observed what Spirulina seemed to provide.

It was nourishing, satisfying, and remarkably sustaining.

Modern science has since explained why. Gram for gram, Spirulina is one of the most nutrient-dense foods we've discovered, naturally rich in highly digestible protein, chlorophyll, vitamins, minerals, essential fatty acids, and an extraordinary range of protective plant pigments.

But in many ways, the laboratories were simply confirming what generations of people had already worked out.

Some foods nourish us far more deeply than others.

From ancient lakes... to outer space

One of my favourite parts of Spirulina's story is that it doesn't end in history books - it reaches into the future.

When scientists began looking for foods that could sustain astronauts during long-duration space missions, Spirulina quickly caught their attention.

It grows efficiently, produces exceptional nutrition in a remarkably small space, and does so with very few resources.

Quite an impressive career progression really - from ancient alkaline lakes to being studied as a potential food for space travel.

Not many foods can claim that.

Why Spirulina still matters today

Over the years I've often been asked which body system Spirulina supports. The immune system? The muscles? The gut? The metabolism?

And the honest answer is... almost all of them.

Not because Spirulina somehow has a different job for every organ, but because healthy cells underpin healthy horses.

That's why you'll find it appearing throughout many of our formulations. Whether we're supporting the gut, recovery, seasonal resilience, immunity, or simply helping horses through more demanding periods, it always comes back to the same simple principle:

Healthy cells build healthy systems.

Perhaps that's why this tiny blue-green organism has remained relevant for billions of years. Sometimes the oldest solutions really are the cleverest.
