Australian Spirulina
Best Quality of Spirulina in the world.

Australian spirulina, the world's the most pure Spirulina compared other 24 products around the world (including USA, UK, Canada, Japan, New Zealand, India).

Al-Dhabi (2013) from King Saud University carried out a research published on Saudi Journal of Biological Sciences on Oct 2013

"Heavy metal analysis in commercial Spirulina
products for human consumption" (Al-Dhabi, 2013).

This study shows the high concentrations of six typical heavy metals/minerals (Nickel , Zinc , Mercury , Platinum , Magnesium , and Manganese) in 25 Spirulina products commercialized worldwide.

The results indicated that Australian Spirulina (TAAU Australia) was the most pure on the market.

The report was published on:

Saudi Journal of Biological Sciences Volume 20, Issue 4 October 2013, Pages 383388 ( click for link)

Summary of Journal paper

List of Spirulina products and their country of origin

12 samples from USA, 1 from Japan, 3 from UK, 1 from India, 5 from Canada. You may ask Why is TAAU the only sample from Australia? because TAAU is the ONLY Spirulina grower in Australia. Other products simply claim to be Australian made. (simply importers, some called Handler as they are described on Ambiguous Australian Ceritified Organic Certificate)

While other Australian Brands rave about their Spirulina product being

"Australian made" or "Australian Certified Organic"

But they never admit their Spirulina is not even grown in Australia. Their Spirulina is 100% imported from other countries.

Ni : Nickel

The lowest was S1 ( TAAU) at 0.211 mg/kg, highest was S2 at 4.672 mg/kg. it's more than 22 times higher than our product. other samples ranged between 1.618 mg/kg (S21) to 3.577 mg/kg(S8), about 7.6 times to 17 times higher than our sample.


Zn : Zinc

Our sample S1 was lowest at 0.533 mg/kg, highest at 6.225 mg/kg (S6), which is about 12 times higher than ours.

Other samples ranged between 1.478 mg/kg (S21) to 5.627 mg/kg (S2), about 2.8 times to 10.6 times higher than our sample.


Hg : Mercury

Again, sample S1 was lowest 0.002 mg/kg, highest is 0.028 mg/kg (S2), 14 times higher than our S1 sample.

Other samples ranged between 0.016 mg/Kg (S18) to 0.026 mg/Kg. (S14) aboout 8 times to 13 times higher than our S1 sample.


Pt : Platinum

TAAU sample S1 was at 0.001 mg/kg, highest was 0.012 mg/kg (S8). 12 times higher than our sample.

Other samples ranged between 0.006 mg/kg (S21) to 0.011 mg/kg ( S4,S7,S9), about 6 times to 11 times higher than our S1 sample.


Mg : Magnesium

No doubt, our S1 was the lowest at 0.002 mg/kg , highest was 0.042 mg/kg (S14), 21 times higher than our sample S1.

Others samples ranged between 0.014 mg/kg (S5) to 0.036 mg/kg(S19) about 7 times to 18 times higher than Ours.


Mn : Manganese

TAAU Sample S1 was at 0.076 mg/kg, highest was 2.248 mg/kg (S19). almost 30 times higher than Our S1 sample.

Others between 0.006 mg/kg (S25) to 1.777 mg/kg (S16).

At Australian Spirulina, we pride ourselves in our quality. From this journal article, it is evident that our Spirulina is of the finest quality in the world.

While other Spirulina companies promote how great their products are and that they are "Certified Organic", they never state where the Spirulina is grown.

It is also important to note that 3 samples were reported from the UK. As we understand, Spirulina cannot grow in the UK due to the colder climate and therefore must import the products from other more tropical countries (most likely from China, India, Thailand, etc).

Canada, Japan, New Zealand are also not suitable for Spirulina production due to their low temperatures and weather. There is no doubt that these products are imported from other counties.

Spirulina requires tropical weather and a pollution free environment, which ensures it's purity and sustainability.

Not all Spirulina manufactured are of the same quality. Budget options are available but are of lower quality from China and India, flooding the market. These products are often masked and labelled in other countries as their own during packaging (such as Made in USA, United Kindom, Australia, or New Zealand, etc). Often customers are not aware that some countries do not produce Spirulina at all.

Good quality Spirulina is never cheap. Being aware of how your Spirulina is grown and where it comes from is more important than chasing "Organic" certificates.
