Hello, I'm Spirulina.

My Benefits

Supports Immunity

Spirulina may be able to help support healthy immune function and immunosenescence. Studies revealed an increase in mean corpuscular hemoglobin, indoleamine 2,3-dioxygenase (IDO) activity, and white blood cell count in senior men and women (1). 

Research also suggests that spirulina may help improve the immune response by covering nutritional deficiencies that lead to poor production of immune cells like T cells, natural killer cells, and cytokines (2). 

Studies conclude that spirulina may help reduce tumor size and growth in certain types of cancers (3). 

Reduces Inflammation

Spirulina and other blue-green algae are high in C-phycocyanin (C-PC), a biliprotein that has been shown to have significant anti-inflammatory and therapeutic effects on the body (4). Studies show that C-PC inhibits proinflammatory cytokine formation and COX-2 expression to reduce inflammation (5). 

Alters Gut Bacteria

Spirulina can support a healthy gut by promoting the growth of helpful intestinal microflora (9). Studies also show it could help reduce inflammation in the gut, improve gut permeability, and prevent gut dysbiosis (10). 

Supports Respiratory Health

Studies show that spirulina supplementation can improve lung function and help support those with respiratory conditions, specifically chronic obstructive pulmonary disease and asthma (8). Much of this is attributed to spirulina’s ability to reduce oxidative damage. 

Lowers Heart Risks

Spirulina may be a natural defense against type-2 diabetes and cardiovascular disease. Studies show that spirulina enhances insulin sensitivity to manage blood sugar levels (11). Spirulina has also been shown to reduce hypertension and blood lipid levels (12).


Improves Mood

Spirulina is high in tryptophan, the natural precursor to 5-HT and serotonin. Studies suggest that spirulina may help to boost mood and improve conditions like depression, anxiety, bipolar disorder, eating disorders, and other mood disorders by improving serotonin levels (15).

Increases Energy

Anemia is a common cause of fatigue and low energy. Studies show that spirulina can increase hemoglobin levels in circulating red blood cells to effectively reduce anemia and boost energy (13). 

Other studies show that spirulina can be used to increase strength and endurance for active individuals (14).

Relieves Allergy Symptoms

Spirulina can help reduce or prevent allergic reactions by releasing histamine from mast cells (6). Studies also show that spirulina effectively reduces allergic rhinitis and symptoms like nasal congestion, sneezing, and itching (7). 

Improves Sleep

Spirulina may help improve sleep disruption by regulating the production of melatonin (16).
