However, buying spirulina online still maybe be a tricky job to get around. Algae can be easily contaminated with different metals and hence you must make sure that you shop from a reliable manufacturer.

What Is Spirulina?

Spirulina is a cyanobacteria that originates from a family of single-celled organisms. This blue-green colored micro-algae grows in both; salt and freshwater sources. People all over the world have been consuming spirulina in some form over the past centuries for its therapeutic and supplementary attributes.

One that you might have come across is blue spirulina, a pretty trendy ingredient in green smoothies.  Spirulina can be consumed in many forms such as raw, fine powder, flakes, pills, and capsules. As a supplement, spirulina powder is the most popular one.

A tablespoon of this superfood provides you 4 grams of complete plant protein, multiple vitamins, minerals and antioxidants (reference). Its rich nutrient profile makes spirulina an attractive supplement for vegans and carnivores alike.

How Does Spirulina Affect Your Body?

By itself, spirulina is not dangerous when consumed in the right amounts. However, when grown in the wrong conditions, there are chances of contamination from bacteria, metals and other toxins.

If ingested without prior confirmation for purity, it might cause nausea, vomiting and other side effects with liver damage in extreme cases of contamination. This reason makes it critical to only shop spirulina supplements from a recognized non-GMO certified manufacturer.

Also, it is always a good idea to consult with your doctor or nutritionist before you add a new supplement to your diet. Depending upon your health conditions and nutritional needs, they can suggest you best if or not you are in need of a supplement.

Overall, spirulina has a host of potential health benefits. It is one of the few vegan foods to contain all essential amino acids in required proportions to be called a ‘complete source of protein’.

Besides it contains essential micronutrients including vitamin B1, B2 and B3, copper, iron, magnesium, and more. As a result, makes for a power-packed addition to your salads, smoothies and soups. The antioxidant and anti-inflammatory properties in spirulina can reduce the risks of fatal diseases like cancer (reference).

As a supplement, it reduces bad cholesterol and raises good cholesterol in the body (reference).
