ALZHEIMER'S +
Spirulina may be useful in treating neurodegenerative disorders such as Alzheimer’s and Parkinsons disease. 
Its powerful antioxidant and anti-inflammatory properties and iron content protect against oxidative stress and decline of neuron functioning. 
It has been shown to prevent memory loss by reducing the deposit of amyloids and reducing oxidative stress.
ANTIOXIDANT +
Spirulina is rich in phycocyanin, a beautiful blue pigment, which is a potent antioxidant. Studies indicate that people who eat plenty of antioxidant-rich foods have reduced risk for disease, increased life expectancy, and are better able to handle stress. Protecting your cells from oxidative stress can also enhance performance during exercise, and prevent muscle damage, speeding post-exercise recovery. 
ANTI-INFLAMMATORY & ANTI-ALLERGY +
Spirulina contains a blue pigment called phycocyanin that has extensive anti-inflammatory and antioxidant properties. Taking Spirulina prevents the release of histamine by immune cells, which reduces inflammation and is anti-allergy. Spirulina has been shown to protect against allergic rhinitis (hay fever), significantly reducing symptoms such as itching, sneezing and nasal congestion. 
CANCER +
The antioxidant and immune modulatory properties of Spirulina may play a role in cancer prevention and tumor destruction. Phycocyanin, the blue pigment in Spirulina, is a powerful antioxidant – preventing DNA damage – and has been shown to have anti-tumor effects. Although there have not been a lot of studies done in humans to date, Spirulina is able to prevent carcinogenesis and to reduce tumor size and growth in animals. 
A selection of relevant studies:
DETOX +
Spirulina is one of the few substances that has a body of evidence supporting its detoxifying action against heavy metals. It is such a powerful detoxifier that it has been shown to reverse the effects of chronic arsenic poisoning. It is a biosorbent of heavy metals and can significantly reduce the toxicity of arsenic, cadmium, lead and mercury. 
DIABETES & BLOOD SUGAR +
Several studies have shown the beneficial effects of Spirulina for people with diabetes. A daily dose of Spirulina improves insulin sensitivity and lowers blood glucose, triglycerides, LDL and total cholesterol levels, improves blood pressure, and reduces inflammation and oxidative stress. 
A selection of relevant studies:
FATIGUE +
Spirulina may reduce physical and mental fatigue. In a clinical study testing 17 healthy men, the participants taking Spirulina showed an increase in exercise output and improved performance on a mental fatigue test. 
Several studies have shown that Spirulina enhances physical endurance, reduces lactic acid production, promotes fat burning and reduces muscle damage, allowing people to perform for longer and recover more quickly.
A selection of relevant studies:
GUT HEALTH +
Spirulina inhibits the growth of ‘bad’ bacteria and stimulates the growth of beneficial gut bacteria, thereby stabilizing the intestinal microbiome, improving gut health and functioning and reducing chronic inflammation. Taking Spirulina together with probiotics makes them more effective. Studies have noted an increase in the abundance of gut bacteria that, among other things, help to reduce blood lipid levels, regulate energy metabolism, improve insulin sensitivity, prevent liver disease, reduce body weight, reduce inflammation and lower cholesterol levels.
A selection of relevant studies:
HEART HEALTH & BLOOD LIPIDS +
Spirulina has been shown to have many beneficial cardiovascular effects. Three months of regular consumption of Spirulina lowered blood pressure and arterial stiffness. Several other studies have shown that Spirulina lowers triglyceride, LDL and total cholesterol levels.
A selection of relevant studies:
HIV +
The immune-boosting, anti-viral, nutritional and blood sugar regulatory properties of Spirulina are all beneficial to people living with HIV. Compounds in Spirulina have been proven to inhibit the replication of HIV. Daily supplementation with Spirulina has been shown to significantly increase CD4 cell count and reduce viral load. Spirulina is also useful for nutrition management and in regulating insulin-resistance and blood lipid levels in HIV patients. 
A selection of relevant studies:
IMMUNE SYSTEM BOOSTING +
Spirulina provides micronutrients and active compounds that stimulate the immune system – boosting the number and activity of white blood cells and increasing production of antibodies. 
A selection of relevant studies:
MENTAL PERFORMANCE +
Spirulina has been shown to improve performance on maths tests, reduce mental fatigue, and improve language and cognitive skills and the intellectual status of school children. 
Studies have found that it may prevent memory loss by reducing amyloid deposition. 
Spirulina during late pregnancy and early childhood, provides critical micronutrients that improve the future learning, working and thinking performance of children.
A selection of relevant studies:
OLDER ADULTS +
Spirulina has been shown to boost the immune system and ameliorate anemia in adults over 50. It also protects against liver inflammation, possibly through changing the gut microbiota. There is evidence to suggest that it may reduce the risk of osteoporosis and memory loss. Spirulina is a rich source of zeaxanthin which has been shown to protect against common age-related eye diseases: cataracts and macular degeneration. 
A selection of relevant studies:
WEIGHT LOSS & CHOLESTEROL +
Spirulina supplementation can significantly reduce body weight, body fat percentage and waist circumference. People who took Spirulina daily had a reduction in appetite, significantly lower BMI and lower triglyceride (fat) and cholesterol levels. Two studies on people with mild hyperlipidemia showed that taking Spirulina every day significantly reduced blood cholesterol, TG and LDL levels.

Unique Natural Healing Compounds

PHYCOCYANIN +
Phycocyanin is a blue pigment-protein complex found only in algae. It is a powerful antioxidant and stimulates the immune system and is known to have anti-viral, anti-cancer, anti-inflammatory and cholesterol-lowering properties. 
More and more studies show that phycocyanin can block the proliferation of and kill cancer cells in multiple types of cancer including pancreatic cancer.
In addition to anti-cancer benefits, research indicates important antioxidant and anti-inflammatory properties with a neuro-protective anti-ageing effect, that it works to protect the heart, liver and kidneys, and may help control or eliminate cataracts. 
A selection of relevant studies:
CHLOROPHYLL +
Chlorophyll is a green pigment present in green plants and algae. The chlorophyll concentration in Spirulina is 10 x greater than in wheatgrass. 
It is a powerful antioxidant — that protects from free radicals that damage cells and DNA — and antimutagenic — that protects against a variety of cancer-causing compounds. 
Chlorophyll seems to prevent cancer cells from multiplying. 
A selection of relevant studies:

ZEAXANTHIN +
Zeaxanthin is thought to play a role in prevention and treatment of eye diseases, particularly age-related degeneration and cataracts due to its blue-light filtering and antioxidant properties. 
Found in high concentrations in the human eye – it may provide significant protection against damage caused by light striking the retina. 
Zeaxanthin may also protect against UV skin damage.
