What, in My Opinion, Is Truly the Best Way to Ensure Your Pet's Needs?

As their first line of defense, your pet depends on their diet to provide antioxidants to help protect them from the negative effects of free radicals caused by stress and pollution.


The number one question I'm asked as a veterinarian is "What's a good multivitamin supplement for my pet?"

That's a tough one to answer.

Ideally, I prefer that your pet receive all the nutrition he or she needs through the foods they eat.

Your pet's body is designed to absorb nutrients from fresh, living foods very efficiently.

However, much as the situation for us humans, your pet's food doesn't always contain the nutrients they need. The Association of American Feed Control Officials (AAFCO) provides the basic vitamins and minerals to sustain life, but certainly not optimal levels of antioxidants and phytonutrients proven to improve well-being, reduce disease and bolster immune defenses and quality of life. Surviving (meeting minimal nutrient requirements) is very different than thriving (providing abundant naturally sourced antioxidants, essential fatty acids and phytonutrients in optimal quantities).

The best of diets – even a raw, species-specific diet – can come from soils that are depleted or from lower quality food sources. Sometimes the food simply loses many of its nutrients through processing and storage.

And most commercially available pet foods, even if they’re “fortified” to meet AAFCO standards, contain synthetic, lab-concocted vitamins and minerals which don’t provide optimum nutrition.

From Their Early Years to Their Senior Yours – Your Pet's Many Needs for High-Quality Nutrition

Pet Needs
Young or old, your pet needs protection from damaging free radicals

Right from the start, your puppy or kitten needs lots of high-quality protein to support the explosive growth that takes place during their first year of life.

And, young or old, your pet needs protection from free radicals, which can hasten aging.

What exactly are "free radicals?"

Free radicals form in your pet's body when oxygen combines with complex metabolic molecules.

These highly unstable molecules travel around your pet's body looking to steal an electron from a stable molecule to stabilize them.

When they successfully snatch an electron, they, in turn, create new unstable molecules, or more “free radicals” with uneven numbers of electrons.

This process is called "oxidation," and once it begins, it can produce a chain reaction that generates more and more free radicals.

The Dangers of Oxidation

Oxidation in the human, feline or canine body is not much different than what happens to a piece of metal when it rusts. As it reacts with oxygen, the metal rusts – or “oxidizes” – and it slowly disintegrates.

In just a few short years, that piece of metal is gone.

Just like that piece of metal, attacking free radicals can cause damage, potentially leading to less-than-optimal conditions in your pet as well as premature aging.

And the oxidative stress resulting from free radical damage can affect your pet's immune system, too. In addition, free radicals can weaken and damage cellular DNA.

As you know, DNA is the “blueprint” of your pet’s cells – that amazing material that directs all cellular activities, including the precise timetable of when cells should divide.

If DNA becomes damaged, cells no longer function optimally. Scientists believe that DNA damage is a major component of the aging process and possibly affects normal cell division and growth.

The Added "Extra" to Support Your Pet's Good Health

Let's consider that piece of metal again.

What if, instead, you painted it? Now you've done a good job of preventing the metal from reacting to the oxygen in the air and oxidizing.

It doesn't rust and it doesn't disintegrate.

Antioxidants are like the “paint” when it comes to helping to protect your pet's body from free radicals.

These powerful nutrients neutralize oxidizing free radicals, rendering them harmless. Antioxidants reduce oxidative stress in your pet's body and protect his cells' delicate DNA. At the same time, cell, tissue, and organ health is supported.

Antioxidants are also important for the health of your pet's eyes. Especially in certain breeds of dogs with more protruding eyes, it is important to help them maintain good eye health.

Antioxidants can help support your dog's eye health as he or she ages.

A healthy diet complete with foods rich in natural antioxidants are important for helping to maintain your pet's eye health and vision.

For valuable support of good eye health, you want to look for antioxidants that can cross your pet's blood brain and blood retina barriers to reach and nourish delicate eye tissues.

The Best Antioxidant Sources for Your Pet

What foods contain antioxidants for your pet?

If you feed your pet a homemade diet, you can add antioxidant-rich foods such as these:

  • Carotenoids: Kale, spinach, carrots, squash, sweet potatoes
  • Vitamin C: Green leafy vegetables, broccoli, Brussels sprouts
  • Vitamin A: Liver, eggs, cheddar cheese, greens, carrots, pumpkin
  • Lutein: Green leafy vegetables including spinach, broccoli
  • Vitamin E: Spinach, sweet potatoes

Spirulina is also an abundant source of carotenoids.

If you'd like to learn how to prepare a balanced homemade diet at home, Beth Taylor's and my book Real Food for Healthy Dogs and Cats provides the recipes and everything you need to know to get started.

Feeding your pet a species-specific diet, loaded with natural antioxidants is a great way of supporting your pet's health.

If you're feeding your pet a commercial diet, you can boost its nutritional value by mixing in some finely chopped, antioxidant-rich foods.

Regardless of the diet you feed, your pet likely has a tremendous need for antioxidants.

And of all the antioxidants I recommend for my furry patients, there's one that truly stands above the crowd.

A member of the carotenoid family, along with beta-carotene, lycopene, and lutein, astaxanthin is by far the “super” antioxidant.

"King" of the Carotenoid Antioxidants…
Astaxanthin Rules

Astaxanthin is considered by many to be “King” of the carotenoids – a potent class of fat-soluble antioxidants. So potent, in fact, astaxanthin's antioxidant capacity is up to…

  • 550 times more powerful than vitamin E
  • 65 times more powerful than vitamin C
  • 54 times more powerful than beta-carotene
  • 5 times more powerful than lutein

Astaxanthin shows very strong free radical scavenging ability and helps protect cells, organs and tissues from oxidative damage. It’s also far more effective than other carotenoids at “singlet oxygen quenching” – a certain type of oxidation.

What also makes astaxanthin especially impressive – and important for your pet in particular – is its ability to cross the blood-brain and blood-retina barriers to support brain and eye health. Very few antioxidants can do that.

Before I tell you more about how astaxanthin can potentially help your pet, there’s one other ingredient you need to know about…

An Algae-Derived Supplement at Its Finest

Spirulina Superfood for Pets
Powdered green spirulina, a quality nutritional supplement for pets

When I recommend a supplement, I believe it's important to use one derived from natural sources. This helps ensure all the cofactors and components naturally found in the plant are included.

With naturally sourced supplements, you don’t get isolated, lab-manufactured vitamins and minerals like those commonly found in commercial diets and supplements. Rather, you receive them as nature intended – as part of the entire plant substance.

The supplement I immediately reach for my furry patients is Arthrospira platensis Spirulina.

Here is what I like about Spirulina:

  • Contains one of the highest concentrations of nutrients in any plant, grain or herb
  • Composed of over 60 percent of complete and easily digestible vegetable protein
  • An abundant source of the hard-to-find essential fatty acid GLA
  • Contains up to 16 percent of its weight of phycocyanin, a bilirubin precursor that powerfully supports normal immune function

Deep within spirulina’s dark green color lies a rainbow of natural pigments: Green from chlorophyll, blue from phycocyanin and orange from carotenoids… all collecting the sun's energy to support healthy, normal growth.

Spirulina is one of the richest beta-carotene plants, with 10 mixed carotenoids, including orange carotenes, alpha, beta, gamma and yellow xanthophylls. These potent antioxidants work together to support health throughout your pet’s body.

When you consider all of spirulina’s attributes, it's easy to see that it contains one of the most powerful combinations of nutrients ever discovered in any grain, herb or plant.

When Spirulina Meets the Super Antioxidant…
Introducing SpiruGreen for Cats & Dogs

Good Health for Pets
My SpiruGreen supports your pet's health in multiple ways

What if you could get both of these amazing ingredients in a single tablet? That you didn't have to choose between the two?

You can with my Healthy Pets SpiruGreen – a unique spirulina and astaxanthin complex.

With SpiruGreen, your pet receives two of nature's most nutrient dense dietary supplements to support healthy, normal:

  • Brain and cognitive function
  • Eye and retinal health
  • Heart and vascular health
  • Immune function
  • Cell division and growth
  • Skin and coat health
  • Movement and flexibility
  • Central nervous system function

SpiruGreen for Cats & Dogs packs a one-two punch with all the nutrient value of spirulina, including carotenoids, phycocyanins and enzymes, plus all the goodness of astaxanthin, one of the world's most powerful fat-soluble antioxidant carotenoids.

After Much Searching, We Found the Very Best…

There's no shortage of individual astaxanthin and spirulina products out in the marketplace. Some good, some not so.

Not until now did we find a product that contains both in one exceptionally high quality tablet. And from a manufacturer that we can fully trust.

The manufacturer we selected for this amazing product is a leading manufacturer of high-quality plant-based nutritional products and ingredients.

To make our SpiruGreen, they combine their Zanthin® brand Astaxanthin technology with organic Spirulina from India to ensure a high-quality product.

Along with using an allergy-free facility for manufacturing this product, there's science and superior world-class manufacturing practices behind it, too.

The Astaxanthin in SpiruGreen Is NOT Your Everyday Astaxanthin… Not Even Close

I've already shared with you how powerful astaxanthin is – and how much more of an antioxidant punch it packs than others.

Astaxanthin is truly one of the most powerful antioxidants ever discovered, as you can see from the ORAC table below. As an antioxidant, it has been shown to be up to 550 times more powerful than vitamin E, 10 times more potent than beta-carotene and 5 times more potent than lutein.

What this high level of antioxidant activity means for your pet is an optimal ability to address oxidative stress.

Antioxidants Values

Unlike synthetic astaxanthin, commonly found in feed formulas and many supplements, the Zanthin® brand of astaxanthin complex found in our SpiruGreen for Cats & Dogs delivers a high-quality extract with scientifically-supported activity.

What's different about this form of astaxanthin?

The Zanthin® brand of natural astaxanthin, like most natural astaxanthin, is manufactured from the microalgae Haematococcus pluvialis. With this microalgae, once the tough cell wall is cracked open it is highly unstable and must be extracted immediately. The difference is that our manufacturer uses a proprietary extraction process that yields a stabilized and standardized 7% oleoresin containing:

  • 85-90% natural astaxanthin
  • 2% lutein
  • 2% carotene
  • 6% other carotenoids

Our manufacturer uses a proprietary DeepExtract™ supercritical CO2 process to extract the astaxanthin rather than toxic chemicals (like many others do). It's far more natural and much safer, too, for your pet and the environment.

And they use a special O2B™ Peroxidation Blocker stabilization technology to help ensure long-term stability and antioxidant activity of the pigments.

When I recommend an astaxanthin product for my patients, I want to know that it's not only a natural product, but it actually delivers the benefits promised. I have 100 percent confidence in this exceptional product.

Why We've Selected Organic Spirulina From India,
and Not the Tropical Beaches of Hawaii

What's important when choosing a spirulina supplement for your pet?

To get the valuable health benefits I've talked about, you want to look for a spirulina supplement that is high in total carotenoids, phycocyanin, zeaxanthin, chlorophyll and gamma linolenic acid (GLA).

And, for truly phenomenal spirulina, we've found that U.S. sources do not always contain the highest concentrations of nutrients.

Here's what I mean… Our manufacturer recently commissioned two independent studies by outside laboratories on the organic spirulina used in our SpiruGreen for Cats & Dogs. They examined a series of batches over a period of several months.

Let me assure you… these studies were complete analytical workups that looked at more than 30 different dietary and nutritional parameters, including vitamins, minerals, fatty acids and carotenoids. These studies especially paid attention to total carotenoid levels, zeaxanthin, phycocyanin, and chlorophyll and gamma linolenic acid.

When compared with published information on Hawaiian spirulina, they found these important differences with the Indian source of organic spirulina in SpiruGreen for Cats & Dogs:

  • Organic spirulina had 8% higher total carotenoids
  • Organic spirulina had 23% more zeaxanthin (a critical carotenoid that supports eye and retina health)
  • Organic Spirulina had equal levels of C-phycocyanin and crude phycocyanin; however, our organic spirulina has the potential to reach higher phycocyanin levels on a consistent basis
  • Organic spirulina had 30% more chlorophyll
  • Organic spirulina had 20% more GLA

As you can see, these are significant differences! And considering we want to offer nothing but the best, we decided to go where the best can be found.

How to Choose a Pure and Safe Spirulina Product

In my opinion, you also want to look for purity when it comes to spirulina, especially because algae absorbs nearly everything it contacts, including toxins.

Here are a few questions to ask the manufacturer when selecting a quality spirulina product:

  • Is it free from pesticides, herbicides, and artificial fertilizers?
  • Does it contain any added synthetic minerals (not a good thing)?
  • Is it produced AWAY from industry, farms, and polluted bodies of water?
  • Does it really deliver the nutrients it says it does? What's the potency?
  • What quality controls measures are in place to help guarantee a quality, toxin-free product?
  • Do you have verification from third-party testing that your spirulina does not contain microcystins, including ß-methylamino-L-alanine (BMAA), a known neurotoxin?

It is vitally important to independently test any spirulina product for microcystins, especially BMAA, as they may present a potential hazard to your pet's liver and brain. Most companies are not doing this.

Far, Far Away, in the Southern Tropical Region of India…

Outside the bustling cities, in a remote area of India, you'll find the manufacturing home of the organic spirulina that goes into our SpiruGreen. Manufactured away from polluting industry and farms, this spirulina is cultivated…

  • With no animal products or wastes
  • With only natural herbal fertilizers
  • With pure, artesian groundwater
  • Without nitrates or manure
  • Without synthetic minerals
  • Without pesticides and herbicides

As a further plus, the manufacturing practices and usage of pure vegetarian organic nutrients help ensure that the heavy metals in this spirulina are the lowest possible.

In fact, this organic spirulina is verified under the U.S. Pharmacopeia ingredient verification program and is also GRAS (“Generally Regarded as Safe”).

Plus, we test our product through a third-party lab to ensure it is free of 15 different microcystins, including BMAA.

It is certified by four major organic standards organizations – USDA NOP, Naturland (Germany), ECOCERT (France) and OCIA-IFOAM (USA).

To meet these exacting standards, no trace minerals – such as iron – are added in the spirulina cultivation process. The practice of boosting the mineral content by adding mineral salts is common with non-organic spirulina.

Quality control includes HACCP (Food Safety Standards), ISO 14001 (Environmental Management Systems) and ISO 9001 (Quality Management Systems) certified by Bureau VERITAS.

How to Supplement Your Pet's Diet With SpiruGreen to
