There are many places to source this superfood, but they are of varying quality.
So how do you find the best Spirulina?
Best Spirulina powder and tablets
Spirulina can be harvested where it grows naturally in warm waters, and is also commercially produced under controlled conditions in many parts of the world.
When harvested correctly from non-contaminated bodies of water, it’s one of the most potent nutrient sources on the planet.
The most important factor when choosing the best Spirulina powder or tablets is knowing that the source is clean from pollutants or chemicals.
You want the goodness of Spirulina without worrying about other things it could have absorbed along the way.
The best Spirulina tablets and powders have been tested for contaminants and state the origin clearly on the label. If the information is unclear, don't buy it.
Some Spirulina products are cultivated in areas that are affected by environmental or industrial pollution.
For example, there have been concerns that Spirulina grown in some parts of China has sometimes been contaminated with lead, mercury and arsenic.
Please also remember that natural lakes have the potential to be affected by pollution and Spirulina will absorb these toxins so always check your source.
