Spirulina is a tiny aquatic plant with a blue-green color produced from species of the cyanobacteria. It is a very rich source of proteins, iron, vitamin A and carotenoids, an antioxidant that protects the body from the harmful effects of free radicals abundant in the environment. It is grown in many parts of the world and used as a whole food or as a dietary supplement. It is also extensively used in aquaculture as fish feed as well as in the poultry industry. It is available in tablet, flake, and powder form.
Pure spirulina is considered a superfood because it contains the essential vitamins and minerals needed by the body such as the B complex vitamins including vitamin B1 (thiamine), B2 (riboflavin), B3 (nicotinamide), B6 (pyridoxine), B9 (folic acid), plus vitamin C, vitamin D, and vitamin E. It is also a very rich source of minerals, including a large amount of potassium, zinc, selenium, calcium, phosphorus, magnesium, sodium, chromium, iron and manganese. It has vitamin K, zeaxanthin or lutein and the essential fatty acid, gamma linoleic acid and some unique pigments that give spirulina their bluish color.
Spirulina has become a household name the world over because of the promise of tremendous health benefits to its users. Thus together with spirulina’s increase in demand also comes the increase in the number of manufacturers who want to have a share of its lucrative market. Because of this, production becomes difficult to control which could compromise quality of the product. This is especially true if you are looking for the pure spirulina product.
Pure spirulina can be obtained from a number of manufacturers who produce it in various forms. The pure spirulina that these manufacturers claim to be 100% pure should contain no other ingredients added to their product, it should be free of pesticides or herbicides, it should not be contaminated by pathogens, pesticides or heavy metal and it should not contain any additives, preservatives or fillers.
You can easily identify a Pure Spirulina tablet because it has retained its original dark green color and it is shiny. On the other hand, an impure Spirulina tablet has white specks and has a dull, light green color. The specks are caused by the binders that have been added to the mixture. In the case of the capsules, it is difficult to check the purity of its contents because it is enclosed and you cannot check the purity of its contents right away.
With regard to the Pure Spirulina flake, you can tell it’s pure because of its invigorating marine fresh aroma. And besides the Pure Spirulina flake did not have to undergo multiple steps to process thus retaining its natural form and nutritional content.
