"The '#1 Superfood' That Americans Are Missing Out On"

It's highly prized in other parts of the world, but sadly not here… Find out why AARP named this a '#1 Superfood' and why you may be missing out on one of the most astonishing health-supporting foods in existence.*


If you eat as the average American eats, you're likely missing out on one of Nature's greatest sources of extraordinary nutrients.

And what's that?


The single-celled microalgae that thrives on sunshine and fresh water.

Different varieties of algae grace the tables of many countries, especially Japan, whose people consume more of it than anyone else in the world.

For good reason, too. Scientists hail its many purported benefits for total body health.*

Sadly, algae remain conspicuously off the plate in American homes. Taste, odor, appearance… for many possible reasons… people in the U.S. and other westernized countries are truly missing out on one of Nature's top sources for important nutrients.

But, as you'll soon see, that's about to change…

Spirulina Named a '#1 Superfood'*

Healthy Lifestyle
The superfood that supports a healthy, active lifestyle*

There are over forty thousand different varieties of these single-celled organisms, but one has consistently stood above the crowd during the last forty years for its spectacular nutrient content.

This acclaimed "superfood" is spirulina.

Spirulina is a variety of fresh water blue-green algae similar in makeup to sea vegetables such as dulse, kelp, nori, kombu, arame, wakame, and chlorella.

However, compared to other sea vegetables, spirulina has been shown to be more easily digestible and have greater nutrient bioavailability.

Having gained international attention and the focus of extensive research, the AARP labeled spirulina as a #1 superfood in its September 2005 issue.

What's more, because of its rich nutrient content and highly available, abundant protein, the United Nations Food and Agriculture Organization identified it as a potential tool in the fight against widespread malnutrition.

Spirulina - In My Opinion, Nature's Nearly 'Perfect' Whole Food

Deep Blue Green Spirulina
Deep blue-green spirulina provides complete, digestible protein along with other important phytonutrients.

Simply stated, containing up to 70 percent protein by weight and with all of the essential amino acids, the quality of spirulina's protein rivals that of the best protein sources.

This even includes milk, eggs, and beef.

However, one must consider the dosing since spirulina is typically used in much smaller levels than these proteins. It typically is considered a supplement and not a protein replacement.

What's more, spirulina is one of the highest, most digestible sources of "complete" protein. A complete protein contains all essential amino acids.

Spirulina contains other important phytonutrients, too:

  • Carotenoids
  • Essential fatty acids, including hard-to-find gamma-linoleic acid (GLA) for your heart and joint health*
  • Minerals such as iron, magnesium, calcium, selenium, and zinc
  • Sulpholipids and the antioxidant enzyme Superoxide dismutase (SOD) all of which are in a bio-available form

And that's not all…

Deep Within Spirulina's Rich Blue-Green Color Lies a Rainbow
of Health-Supporting Pigments*

Within spirulina's deep, dark color lies an impressive array of natural pigments.

Green from chlorophyll… blue from phycocyanin… and orange from carotenoids… all collecting and passing along the sun's energy and supporting your healthy, normal growth.*

In fact, spirulina is one of the highest sources for phytopigments like phycocyanin, beta-carotene, zeaxanthin and other plant pigments.

One of the richest beta-carotene foods in existence, spirulina's ten mixed carotenoids, including orange carotenes, alpha, beta, gamma, and yellow xanthophylls, work within your body.*

Research suggests spirulina's potential benefits for promoting total body health, including…

  • Promoting normal immune response*
  • Promoting optimal gastrointestinal flora*
  • Supporting optimal digestion*
  • Helping to maintain normal blood pressure levels that are already within the normal range*
  • Helping to maintain normal blood sugar levels that are already within the normal range*
  • Promoting increased seasonal comfort*
  • Supporting heavy metal detoxification*
  • Promoting optimal cardiovascular health*
  • Supporting normal immune system activity*
  • Curbing hunger and promoting a feeling of increased energy*

Of all the phytopigments found in spirulina, there is one in particular generating much interest among scientists…

The Unique Pigment Found Only in Spirulina…

Spirulina is especially recognized among scientists for its phycocyanin content, the vibrant phytopigment that gives spirulina its natural bluish tint.

Studies show that phycocyanin may have multiple health benefits, including support of brain and heart health, protection against oxidative stress, and the promotion of a healthy immune system.*

In mammals, phycocyanin converts to phycocyanorubin, an antioxidant very close in structure to bilirubin.

Why is this important? Evidence suggests bilirubin can protect tissues against free radical-caused oxidative damage.* In fact, slightly elevated bilirubin blood levels have been linked to normal healthy cardiovascular function.*

Phycocyanin is found only in spirulina. And it's plentiful, too – phycocyanin makes up about 16 percent of spirulina's total weight.

Plus, phycocyanin may play a major role in stem cell regeneration, especially in bone marrow and blood cells.* Phycocyanin supports the creation of the red blood cells that oxygenate your body and the white blood cells that make up your cellular immune system.*

What's more, scientists have discovered that the phycocyanin in spirulina supports white blood cell production.*

Whole Food Nutrition

When I do recommend a supplement, I believe it's important to use one derived from safe, whole foods. This helps ensure that you receive all of the cofactors and enzymes naturally found in the food along with the vitamins and minerals.

With whole food supplements you're not getting isolated, lab-manufactured vitamins and minerals like those typically found in many supplements. Rather, you're receiving them as nature intended – as part of the entire food.

Spirulina powder is readily available today, both online and in health food stores.

Problem is, many people shun spirulina because of its strong algae scent and taste. Commonly added to smoothies and green drinks, the taste of spirulina is difficult to mask. You either love it or you don't…

Another option is to include generous quantities of sea vegetables such as kombu, kelp, arame, dulse, kelp, nori, or wakame in your everyday diet, just like 95 percent of the Japanese population.

Warning: Spirulina and Nutrient-Rich Sea Vegetables
Aren't Always Good for Your Health

Avoid Tropical Algae
Be sure to avoid any spirulina or sea vegetables grown in areas subject to radiation fallout.

As healthy as spirulina, kelp, and other sea vegetables may be, here's a word of caution if you do include them in your diet now...

Just as eating some fish can negatively impact your health because of heavy metal and chemical contamination, most sea vegetables and many natural sources of spirulina are now contaminated as well.

Plus, many sea vegetables have been found to contain bromine instead of iodine.

And since the Fukushima nuclear incident, I recommend that you avoid any sea vegetables, including spirulina and kelp, from Japan and nearby waters harvested after March 1, 2011 as they may be contaminated with radiation.

If you can be certain the sea vegetables you choose to eat are toxin- and radiation-free, I believe this is the ideal way to obtain the important whole food nutrients you need.*

However, if you're like most Americans and other Westerners, I'm guessing that sea vegetables are not likely to fill your plate on a daily basis anytime soon…

For that reason, I am now recommending that you include a supplemental source of spirulina in your diet every day for that added measure of nutrition.*

But be careful, freshwater algae like spirulina can contain high levels of microcystins, toxins that can damage your liver and brain. Microcystins have the potential to be produced in large quantities during algae blooms, so it's important that spirulina be grown in a clean, controlled environment and independently tested for safety.

Since Not All Sources Can Be Trusted…
How Do You Find a Spirulina That's Nutritious and Safe?

There's no shortage of spirulina products in the marketplace. How do you know which is high in important nutrients? And which one you'd feel comfortable taking yourself and giving to your family?

When choosing a spirulina supplement, here are some of the important nutrients that I believe you should look for…

  • Total carotenoids
  • Phycocyanin
  • Zeaxanthin
  • Chlorophyll
  • Gamma linolenic acid (GLA)

To safeguard you and your family, I recommend that you make sure your source is organic and has independent third party lab verification that the spirulina is both toxin- and radiation-free and contains iodine and not bromine.

Know your source. Some less-than-optimal brands add animal wastes to deceptively boost protein levels. Insist on vegetarian organic nutrients in your spirulina supplement.

We Searched for a Long Time... And We Finally Found What I Believe Is the Best Source of Spirulina

Organic Spirulina
The source of our organic Spirulina is SpiruZan™ from Oonaiyur, a remote area far away from polluting industry.

Not until now have we found a spirulina that I can fully trust and recommend to you.

This organic spirulina comes to us from a leading manufacturer of high-quality plant-based nutritional products and ingredients.

I'm pleased to say that they've been producing spirulina for over 30 years and have conducted more than 25 in vitro and in vivo studies on their product on both humans and animals.

Our Chief Research Scientist has visited the ponds where the spirulina is grown, located twenty miles away from the historic town of Pudukottai in South India. The place is called Oonaiyur, a quiet, pristine stretch of land far away from any polluting industrial or agricultural activity.

Free from ground water contamination, and far away from pesticide, herbicide, and synthetic fertilizer use, our spirulina microalgae is grown across this vast hundred and thirty acres of land.

The ponds where the spirulina is grown are incredibly clean and well-maintained, as is the processing and extraction equipment used. The facility is organic certified by European 3rd party assessors, which comply with the USDA National Organic Program Standards.

This unwavering commitment to maintaining a pristine environment ensures our organic spirulina is...

  • Low in heavy metals, yeast and mold.
  • Grown without Chilean nitrate, manure or synthetic minerals.
  • Non-GE (genetically engineered) and non-irradiated.
  • Produced without herbicides, pesticides, gluten and harsh chemicals.
  • Grown with only natural herbal fertilizers and pure, artesian groundwater.
  • Third-party tested to ensure it’s free of 15 different common microcystins, including ß-methylamino-L-alanine (BMAA).

As a further plus, the manufacturing practices and usage of pure vegetarian organic nutrients help minimize contamination from toxic heavy metals. Each batch of our spirulina is tested to ensure consistent quality and nearly undetectable heavy metal content.

Our spirulina manufacturer also takes care to ensure that the conditions in the pools are not suitable for mycrocystins. You can rest assured that these dangerous toxins are never present in our product.

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

When the '#1 Superfood' Meets the 'King of the Antioxidants'…
Spiru-Blue Emerges

Born white, flamingos develop their vibrant glow once they start eating their astaxanthin-rich diet.

As near-perfect as spirulina may be, it does lack one key carotenoid.

That missing carotenoid is astaxanthin.

Now, if you've been visiting my site lately, you'll quickly recognize that hard-to-spell word. It happens to be one of the most powerful antioxidants discovered to date.*

In fact, it's considered the "King" of the carotenoid antioxidants by many who have studied it.

So, it only stands to reason… why not make a near-perfect food even more perfect by adding the "king of the antioxidants"?*

To make our remarkable combination product called Spiru-Blue, our manufacturer combines certified organic spirulina with a very special form of astaxanthin.

Just in case you're not familiar with astaxanthin, I'll give you a quick review of its amazing benefits…

Simply, astaxanthin is what puts the rosy glow in flamingos and the scarlet coloring in lobsters, shrimp, and krill.

Born white, these animals and crustaceans gain their brilliant color after feeding on microalgae, the source of the red pigment astaxanthin.

Neither animals nor humans can produce their own astaxanthin, so the only way to get it is to eat something in the food chain of the microalgae itself.

How Astaxanthin Supports Your Health*

Truly the "King" of the carotenoids, astaxanthin's ability to scavenge free radicals in your body* 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

It does this by quenching a molecule called singlet oxygen - a harmful reactive oxygen species formed through normal biological processes occurring in your body.* Singlet oxygen possesses a high amount of excess energy that must be released to keep it from damaging other cells.

Astaxanthin absorbs this energy and dissipates it as heat, thereby returning the singlet oxygen to a grounded state.*

There's another way, too, that astaxanthin helps to protect cells, organs and tissues against oxidative damage from free radicals.*

It traps free radicals at both ends of the molecule.* Once captured, the potentially harmful free radicals pass into cellular fluids where they become neutralized by vitamin C. In this way, astaxanthin is sometimes considered a 'booster' for other antioxidants like vitamins A, C and E.*

What's more, astaxanthin can't act as a potentially detrimental "pro-oxidant" like some of the other carotenoids such as beta-carotene, lycopene, and zeaxanthin.

  • Support your joint health, flexibility, and mobility*
  • Support a healthy immune response*
  • Support your central nervous system*
  • Support your cardiovascular system*
  • Support your brain and eye health due to its unique ability to cross blood-brain and blood-retina barriers*

Especially because we face so many stressors in our everyday lives, I now believe astaxanthin has an important role in everyone's daily regimen.*

What, in My Opinion, Makes Our Astaxanthin Stand Shoulders
Above Some Other Astaxanthin Supplements?

You've just seen how powerful astaxanthin is - and how much more of an antioxidant punch it packs than other antioxidants.

But the Zanthin® brand of astaxanthin complex found in our Spiru-Blue delivers a high-quality extract with scientifically supported activity. It's even patented for use in eye health formulas.*

As you can see in the ORAC table below, Zanthin® astaxanthin delivers over THREE times the free radical scavenging activity as synthetic astaxanthin, the form commonly found in other supplements.*

ORAC values of antioxindants

So why is this form of astaxanthin more effective at protecting your body against free radicals?*

The DeepExtract™ Process Delivers More of Nature's Bounty

The Zanthin® brand of astaxanthin is manufactured from the microalgae Haematococcus pluvialis, nature's most plentiful source yet discovered.

In its natural environment, the microalgae Haematococcus pluvialis produces astaxanthin as a protective measure when its water supply dries up.

During processing, once the tough cell wall of the microalgae is cracked open, the astaxanthin is highly unstable and must be extracted immediately. Our manufacturer uses a proprietary extraction process that yields a stabilized and standardized 7% oleoresin containing:

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

Unlike other processing methods that use toxic chemicals to extract the astaxanthin, our manufacturer's proprietary DeepExtract™ supercritical CO2 process yields a product that's more natural, and safer too, for you and the environment.

DeepExtract™ offers gentle treatment of high-quality astaxanthin at much lower temperatures than those used in expeller press and certain chemical solvent extraction operations. And it's done in the absence of oxygen – which reduces degradation and chemical changes in the product.

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

All this means it stays fresher on your shelf – up to 24 months!

So, with Spiru-Blue, you receive 300 mcg per dose (75 mcg per pill) of high quality astaxanthin that's:

  • Untouched by chemical solvents
  • Free of impurities and residues
  • No genetically engineered ingredients
  • Stable, fresh, and long-lasting

When I recommend an astaxanthin supplement, I want to know that it's not only a natural product, but it actually delivers the benefits promised. I have 100 percent confidence that this exceptional astaxanthin does that and more.

Top 13 Frequently Asked Questions
  1. 1. Q: How is Spiru-Blue different from chlorella?

    A: Spiru-Blue is a combination of organic spirulina, Zanthin® natural astaxanthin complex, and blue phycocyanin from organic spirulina.

    Both spirulina and chlorella are forms of algae. However, the main difference between the two is spirulina does not possess the hard cell wall that makes chlorella resemble a plant more than algae.

    Spirulina is a "super food" that nourishes your body with its abundant protein, helps support your immune system, and maintains cholesterol and blood pressure levels that are already in the normal range.*

    Spirulina is especially recognized among scientists for its phycocyanin content, the brain, heart, and immune supporting phytopigment that gives spirulina its natural blue tint.*

  2. 2. Q: I've heard that sea vegetables may be contaminated and unsafe to eat. How can I be assured this spirulina is safe?

    A: You're wise to be careful, especially since the Fukushima nuclear incident has contaminated sea vegetables, including kelp and spirulina, in the Western Pacific waters surrounding Japan.

    Choose only organic sources that have independent third-party lab verification that the spirulina is both toxin- and radiation-free and contains iodine, and not bromine.

    The spirulina we use in Spiru-Blue comes from a pristine area in South India, far from pollution, ground water contamination, pesticides, herbicides, and synthetic fertilizer use. Our trusted supplier has been producing high-quality organic spirulina for over 30 years.

  3. 3. Q: How soon after I take this can I eat?

    A: Ideally, take spirulina 30 minutes before meals to allow your body optimal absorption of the nutrients without food in your stomach.
