Best Organic Spirulina Powder & Supplement – October, 2020 Reviews & Buyers Guide

Spirulina powder is algae, or cyanobacteria, that is blue-green, and one of the most nutritionally dense superfoods on Earth. Spirulina is versatile and a “must” in everyone’s kitchen arsenal. It grows in fresh and saltwater in warm climates and is dried after it’s harvested. It absorbs the nutrients from the water in which it grows, in combination with the suns rays, so it’s ideal to have a pure water source for ultimate quality.

This nutritious powder and supplement were first thought to be used by the Aztecs in 16th century Mexico, where it was harvested from Lake Texcoco. They would refer to it as “Tecuitlatl,” which means “stone excrement.”

Don’t fret- you’re not eating stone “poop!” That’s just a funny term they named it way back when.

As the Aztecs main source of protein, they liked to bake spirulina and dry it into cakes to snack on (think of a big chip). It’s currently consumed by millions all over the globe due to its overwhelming nutritional value. It’s full of chlorophyll, protein, antioxidants, and B-vitamins. But, it’s mainly protein and essential amino acids.

The unique smell of spirulina that many talks about comes from the sulfur content in the algae.

If you’re pregnant, recuperating from a surgical procedure, or getting over a cold, spirulina would be helpful due to its high levels of protein and iron. Proteins help promote tissue healing and are required for tissue growth.

Spirulina powder has been compared to eggs for its protein content per gram. It’s readily usable protein, too! This means our body does not have to work hard (or really at all) to digest the protein.

Organic spirulina powder and supplements are also teeming with other nutrients, such as Vitamins C, D, and A, potassium, magnesium, manganese, phosphorus, and calcium.

It’s often mistakenly believed that spirulina has large amounts of vitamin B-12, but this is a myth, as the body is unable to absorb this pseudovitamin, nor is it even effective.

Spirulina powder is also revered for its Gamma Linolenic Acid (GLA) and Omega-3 fatty acid content. GLA wards off inflammation and omega 3’s have numerous health benefits, including a reduction in anxiety and enhancing overall mental health. Spirulina is one of the only foods with a natural GLA content of this sort.

Spirulina powder has proven helpful in lowering blood sugar, so much so that diabetics find spirulina to be as effective as prescribed diabetic medications, in some cases.

This colorful powder is also effective in decreasing heavy metals from the blood via your excrement, by binding with and removing them.
