2. Promotes cardiovascular health

Spirulina turns out to be favorable for cardiovascular health . It is an antioxidant food, capable of controlling lipid levels in the blood, that is, reducing the development of LDL cholesterol or waxy substances such as triglycerides, even improving the development of platelets for coagulation.

Spirulina may also be helpful in controlling blood glucose . It is an ideal food for diabetics, on the one hand because it lowers cholesterol or lipids that are involved in glucose. 

On the other hand, it provides polysaccharide carbohydrates necessary for type 2 diabetes and as a replacement for insulin, so it can be said that it has hypoglycemic effects.

4. Reduces the action of free radicals

Spirulina becomes so important that it is capable of reducing the effects of free radicals.

With this, cellular oxidative damage to DNA is prevented, apart from preventing chronic diseases, this is possible since food is an essential antioxidant that works with the inhibitory enzymes of the organism , in order to reduce oxidative stress.

To highlight: A study adds that: “Phycocyanin is a powerful radical scavenger that inhibits lipid peroxidation, present in abundance in the structure of Spirulina . ” (two)

5. Improves brain health

Spirulina can dramatically improve brain health in the nervous system, for multiple reasons.

It mainly stimulates the production of hormones such as serotonin and melatonin , apart from being protective of the neural networks of the brain, not to mention that it also improves the flow of blood, essential proteins and oxygen to the brain tissue, which keeps this organ in full and good condition. functioning.

6. Promotes liver, kidney and visual health

Spirulina is wonderful for liver health, since the melatonin compound provides proteins and enzymes for the liver system , in addition to stimulating regeneration and elimination of toxins in the same organ.

This is because xanthine improves skeletal muscle contractions, which is favorable for increasing muscle mass , where essential proteins that are housed in muscle tissue also play a key role, providing energy and strength to the muscles. themselves.

8. Fights anemia

Spirulina is a food that can combat anemia and its symptoms. Reduces fatigue by improving brain activity, along with providing enough iron, mixed with the necessary antioxidant agents that help stimulate the production of red blood cells, improve the quality of hemoglobin and reduce feelings of fatigue or intense dizziness .

9. Contributes to weight loss

Spirulina can contribute a lot to weight loss, in cases of obesity. This food can effectively stimulate the body’s metabolism, achieving greater fat burning and providing the body with enough calories, taking into account that it is capable of generating full satiety in the face of hunger.

3. Other compounds

Spirulina or spirulina, has other content of important compounds such as fiber , phycocyanin (the pigment that gives it its blue-green color), amino acids, proteins , xanthine, essential fatty acids such as saturated, polyunsaturated and monounsaturated, apart from lipids. , chlorophyll, calories and carbohydrates.

How is spirulina consumed?

The consumption of spirulina is done in two special ways, because they maintain the nutritional content. The first is in the typical form of greenish powder, which is used as a seasoning for various foods such as salads and soups, adding flavor or color that is even pleasant and helps the digestive system due to antioxidants.
