Benefits to the body

Spirulina is suitable for anyone who wants to take care of their health and appearance. However, there are a number of special circumstances when spirulina will show its power.


Spirulina is an alternative to traditional anti-allergenic drugs. It can help reduce the symptoms of allergic rhinitis by “calming” the cell’s reaction to allergens. For example, pollen.

Cleansing the body

Spirulina contains chlorophyll, beta-carotene, zeaxanthin and phycocyanin, which are powerful antioxidants. They can neutralize oxidative damage caused by free radicals. By removing free radicals, we protect our body from the risk of cancer and cardiovascular diseases.

Spirulina can help protect healthy cells from the negative effects of radiation therapy after cancer treatment. Its useful components save cells from the toxic effects of chemotherapy. But please note that if you are undergoing cancer treatment, consult your doctor before taking any supplements.

Normalization of cholesterol

High cholesterol is a risk factor for heart disease. Spirulina will help lower cholesterol and blood pressure. 1 gram of spirulina taken daily for 12 weeks can reduce total cholesterol by 16%. It also lowers triglycerides and “bad” cholesterol.


Type 2 diabetes is the main cause of heart disease, strokes, kidney disease and memory impairment. A person with type 2 diabetes can control glucose levels by monitoring their diet and exercise, and oral medications are often prescribed to a patient in need of further help. Spirulina can also be a useful addition to your daily routine.


Spirulina has anti-inflammatory properties and can help with any pain associated with arthritis. It reduces inflammation by reducing the level of COX-2 enzyme in the blood.

Several possible side effects from the use of spirulina:

Increased body temperature.
After taking spirulina, your metabolism will increase, so you may feel a slight increase in body temperature.

This side effect is temporary. Acne is just the result of cleansing the colon of toxins. Ultimately, taking this supplement will cleanse your skin.

Green chair.
