Spirulina is a microscopic spiral shaped, blue-green vegetable algae. Spirulina is highly digestible and the most nutritious, concentrated whole-food known to humankind. 

Spirulina contains:

* More than sixty five percent complete highly digestible protein per serve and all essential amino acids;

* More beta-carotene than any other whole food;

* Nature’s richest whole-food source of iron. 

* Excellent sources of K1, K2 and B12; and 

* Source of health-giving phytonutrients such as carotenoids, GLA, SOD, and phycocyanin


Here is what science and research says about Spirulina:

IMMUNE SYSTEM: Spirulina is rich in vitamins essential for maintaining a healthy immune system, such as vitamins E, C and B6. Spirulina can enhance the rate of production of antibodies, and also red and white blood cells by enhancing hematopoiesis, the formation of blood cellular components. Spirulina also shows direct effect on both innate and specific immunity. Spirulina activates macrophage, natural killer cells and T-cells, for an effective immune system. 

CARDIOVASCULAR HEALTH: Studies have shown that the protein component in spirulina can decrease our body’s absorption of cholesterol, which can lower cholesterol levels keeping the arteries clear. This protein can also reduce triglyceride levels, which are the fats in our blood which can contribute to our arteries hardening, increasing the risk of heart disease. 

In a randomized, double-blind, placebo-controlled study, patients with hypertension but free from other cardiovascular diseases, after 3 months of supplementation with 2g Hawaiian spirulina, showed a significant reduction in systolic blood pressure and body mass index, and an improvement of endothelial function. 

BRAIN HEALTH & ENERGY: Spirulina contains a powerful plant-based protein called phycocyanin, and studies have found that this protein may have brain-protective properties. Research is now finding that Spirulina can offer neuroprotection, antioxidant and anti-inflammatory mechanisms in the brain parenchyma, which could prevent neurodegenerative or psychocognitive pathologies, in particular where there is an inflammatory component present. Research has also found Spirulina to help with physical and mental fatigue, which may be due to the high levels of brain nutrients.

EYE HEALTH: The high levels of beta-carotene in Spirulina can provide benefits to improving and maintaining good eyesight. Spirulina is concentrated with zeaxanthin, a plant pigment which can decrease the risk of cataracts and age-related vision loss. 

ALLERGY RELIEF: The antioxidants spirulina contains can have an anti-inflammatory effect. This may help people who suffer from allergies caused by dust, pollen and animal hair. A study of participants with allergies who consumed Spirulina found that symptoms such as sneezing, itching and congestion, was significantly reduced, suggesting that spirulina could help with allergy sufferers. 

There are so many more benefits of spirulina, these are just to name a few!
