What Is Hawaiian Spirulina Green Complete?

The product is an all-natural, green superfood with Hawaiian Spirulina as its star ingredient.

Spirulina is a blue-green microalgae, Arthrospira platenesis, grown in Hawaii. It contains protein, iron, beta carotene, minerals, vitamin B12, zeaxanthin, chlorophyll, and phycocyanin.

According to the website:

One 3 gram serving has higher levels of some key antioxidants, enzymes, and minerals compared to 5 servings of fruits and vegetables.

Along with the spirulina, there are greens, antioxidants and probiotics.

Some of the unique benefits of Hawaiian Spirulina Green Complete Superfood, according to the official website include:

  • More nutrition, gram per gram, than any other Spirulina on the market
  • Complete protein with essential and non-essential amino acids
  • 60% protein and is an excellent source of vitamins A, K1, K2, B12, and iron

It is manufactured by Nutrex Hawaii Inc., established in 1999 in Kailua-Kona, Hawaii.

Hawaiian Spirulina Green Complete Ingredients


Spirulina contains carotenoids which support vision, cardiovascular and skin health among other benefits.

It also contains gamma linolenic acid (GLA), a lesser known omega-6 fatty acid. It reduces inflammation, including symptoms of rheumatoid arthritis, improves attention deficit hyperactive disorder, and eczema.

Superoxide dismutase (SOD) is also found in spirulina. SOD acts as a powerful antioxidant which helps protect cells from damage.

Phycocyanin is another substance found in spirulina that has been shown to lower blood pressure, support kidney, liver and brain health.

Spirulina also has a host of other vitamins and minerals.

Organic Greens Blend

Contains vitamin A which supports vision, vitamin C which plays a role in collagen formation and vitamin K which protects against heart disease, diabetes and osteoporosis.

The blend also includes folate which contributes to vision and heart health. While omega-3s promote healthy heart and blood pressure.

Antioxidant Blend

Organic Dulse, organic acai, organic Goji berry.

This blend prevents free radical damage, detoxifies and strengthens cells.


Echinacea Angustifolia Extract 4:1, Organic Licorice Root, Royal Jelly 3x Concentrate, Organic Milk Thistle

The immunity blend fortifies the immune system.

Probiotic Blend

Saccharomyces boulardii.

This is a yeast and a probiotic used mainly to prevent diarrhea. There is some evidence that it is useful in reducing acne.

How Does Hawaiian Spirulina Green Complete Work?

Hawaiian Spirulina Pacifica is cultivated in open ponds using fresh potable water and deep ocean water.

The patented drying system used by the company eliminates the oxidation of carotenes, enzymes and fatty acids that occurs in standard dryers preserving the potency of the ingredients.

The ingredients maintain their effectiveness and ability to provide energy, improve immunity and support eye, brain and heart health in addition to a host of other benefits.

How To Use It?

One scoop should be taken daily with 8 ounces of water, juice or in a smoothie.

While the product may be taken at any time, it is advisable to take it at least 4 hours before bed as the energy boost it provides may interrupt sleep.

Hawaiian Spirulina Green Complete Side Effects

Nutrex makes every effort to ensure the purity of their formula.

All ingredients are organic.

The Hawaiian Spirulina Green Complete Superfood contains no soy, gluten or dairy.

It is also non-GMO, pesticide and herbicide free and vegan.

Nutrex conducts a series of 15 different tests for microbials, heavy metals and other contaminations. They also allow third-party testing of the product.

The company also periodically tests for microcystins and have never found any.

Microcystins are toxins that develop from cyanobacteria that may cause liver damage and cancer if ingested long term.

Most of the products included in the formula are food-based and generally quite safe, however, there are some exceptions.

Spirulina contains iodine, an essential nutrient and generally safe to ingest for most people.

However, in some people, iodine may cause nausea, stomach pain, runny nose, headache, metallic taste, and diarrhea.

Beta-carotene, the material used by the body to make vitamin A in the form of retinol.

Vitamin A is necessary for healthy vision, skin and immune system among other things.

The body regulates retinol conversion, so overdosing on beta-carotene has no permanent adverse effects as long as the beta-carotene comes from food sources.

When this happens, the skin and nails may turn orange or yellow but this is temporary and can be reversed by reducing intake of beta-carotene.

Overdosing on beta-carotene supplements can have serious and even fatal side effects specifically in smokers who have a higher risk of developing lung cancer.

Since spirulina is a natural food source, beta-carotene overdose is not an issue.

Another possible cause of side effects is a sensitive digestive system.

Some people may experience stomach pain, nausea and other symptoms due to the potency and bioavailability of the product.

Is It A Scam?

Nutrex Hawaii has an A+ rating with the Better Business Bureau.

The company’s stringent manufacturing and quality control processes exceed the standard requirements to ensure the purist, highest quality product.

The company has been in existence since 1999 and there are no legal issues associated with them.

The company and its products are definitely not a scam.

This stuff is a gift from God I live off this stuff for my protein needs.

Love love love. Makes me feel very euphoric too.

Sunflower Darling:

I just started taking for the first time and its only the second day, but so far the first thing I noticed is I am urinating a lot more. I added a tea spoon to my morning smoothie that already had Turmeric.

Also I have insomnia and last night I went right to bed with no problem and woke up today feeling good and well rested. Very excited to see the additional results with the longer I use. I highly recommend it.

A few customers experienced issues.

Sorry to say, I had a very negative experience with this product. I experienced a break out on my face, dizziness, and stomach pains. I have not had any of those reactions with other types of spirulina I have tried. I returned it.
