What Gives Salmon Their Strength and Colour — And Why It Matters for Your Pet

Have you ever wondered why wild salmon have that deep pink colour?

It’s not artificial. It’s not random.

That colour comes from a naturally occurring compound called astaxanthin — a powerful antioxidant found in marine life.

It’s also one of the reasons salmon can do something extraordinary:

swim long distances upstream against strong currents.

That kind of endurance doesn’t happen by accident.

And while your pet isn’t about to swim upstream for miles, the reason astaxanthin matters in nature is also why it can be valuable in daily pet nutrition.

What Is Astaxanthin?

Astaxanthin is a naturally occurring carotenoid produced by microalgae and passed up the marine food chain.

That’s why it’s found in:
• Krill
• Shrimp
• Wild salmon

In nature, it acts as a protective compound — helping organisms deal with stress and supporting cellular resilience.

Why Antioxidants Matter

Your pet’s body is constantly working:

• Producing energy
• Repairing tissue
• Processing nutrients

As part of this, it naturally produces free radicals.

That’s normal.

But when these build up faster than the body can manage, it creates internal pressure known as oxidative stress.

Antioxidants help the body manage that stress and support cells over time.

What Makes Astaxanthin Different?

There are many antioxidants — but astaxanthin stands out.

It has a unique structure that allows it to support both the inner and outer parts of cell membranes. In simple terms, this means it can help provide antioxidant support in areas where cell protection is especially useful.

It’s also fat-soluble, which makes it particularly effective when paired with marine oils.

Why This Matters for Your Pet

Most pet owners aren’t thinking about antioxidants.

They’re thinking about:

• Comfort
• Movement
• Coat condition
• Energy
• Vitality

Astaxanthin matters because it supports the body at a foundational level — where many of these outward signs begin.

Not as a quick fix.

But as consistent support over time.

Why Marine Ingredients Work Better Together

In nature, astaxanthin doesn’t exist alone.

It’s found alongside marine fats in animals like salmon.

That matters because it needs the fat to be properly absorbed.

So combining it with a quality marine oil isn’t just convenient — it’s logical.

Why We Pair It with New Zealand Hoki Oil

At Newflands, we combine natural astaxanthin with premium New Zealand hoki oil.

Hoki oil provides omega-3 fatty acids (EPA & DHA), supporting:

• Joints
• Skin and coat
• Brain and nervous system
• Overall wellbeing

When paired with astaxanthin, it becomes more complete daily support — helping the body manage both oxidative stress and normal inflammatory processes.

Common Questions About Astaxanthin for Pets

What is astaxanthin?

Astaxanthin is a natural marine antioxidant and carotenoid. It is produced by microalgae and moves through the marine food chain into krill, shrimp, and wild salmon. It is one of the compounds responsible for salmon’s natural pink colour and helps support cellular resilience against oxidative stress.

Why does astaxanthin matter for pets?

Astaxanthin matters because it helps support the body’s natural antioxidant defences. In pets, this can be useful for daily support of cellular health, skin and coat condition, mobility, vitality, and healthy ageing. It is not a quick fix, but it can be part of consistent long-term wellness support.

Is astaxanthin the reason salmon are pink?

Yes. Wild salmon get much of their natural pink-orange colour from astaxanthin in the marine food chain. Astaxanthin comes from microalgae and is passed through organisms such as krill and shrimp before being consumed by salmon. This is part of what makes salmon colour a useful way to explain how marine antioxidants work in nature.

Is astaxanthin good for dogs and cats?

Astaxanthin can be a useful antioxidant for dogs and cats when used appropriately as part of a balanced wellness routine. It may support cellular health, skin and coat condition, mobility, vitality, and healthy ageing. It should not replace veterinary care, and any pet with health concerns, medication, pregnancy, or complex needs should be discussed with a vet first.

Why is astaxanthin paired with hoki oil in Omega-i?

Astaxanthin is fat-soluble, which means it works well when paired with a quality marine oil. In Omega-i, Newflands combines natural astaxanthin with New Zealand hoki oil to support daily antioxidant intake, omega-3 nutrition, skin and coat condition, mobility, vitality, and healthy ageing. This pairing reflects how marine nutrients naturally work together rather than treating each ingredient in isolation.

I chose to use astaxanthin in Omega-i because it made sense to me from both a marine nutrition and lived pet-care perspective. Over the years with my own dogs, I have seen how skin, coat, movement, and brightness can shift quietly before there is an obvious problem. Pairing a marine antioxidant with New Zealand hoki oil felt like a more complete way to support pets daily, rather than relying on omega-3 alone.

 

Where Omega-i Fits In

Omega-i was created to bring these two ingredients together in a way that makes sense.

• Natural astaxanthin
• Premium New Zealand hoki oil

Together, they support:

• Cellular health
• Mobility
• Coat condition
• Healthy ageing
• Daily vitality

Not hype.
Not trends.

Just thoughtful support built around how the body actually works.

For readers who want to understand the science behind astaxanthin, Science Direct has a useful overview of astaxanthin as a carotenoid antioxidant found in algae, salmon, trout, shrimp, and other marine life.

Because sometimes the most powerful support comes from understanding what nature has been doing all along.
