Due to its excellent nutritional content, which confers numerous benefits for the proper functioning of the body, many people consider spirulina as a “superfood”. It has a high content of proteins and vitamins, which is why it is indicated as a food supplement for people who follow vegetarian or vegan diets.

We have already seen that spirulina has antioxidant and anti-inflammatory properties, as well as the ability to balance the immune system.

Spirulina increases the body’s defense capacity against infections, regulates the feeling of hunger, favors digestive processes and stimulates the regeneration of liver cells. Last but not least, it contributes to the reduction of “bad” cholesterol and has a beneficial effect in improving and preventing eye diseases.

Numerous antioxidants in Spirulina have an anti-inflammatory effect, which is very beneficial, because chronic inflammation leads to the appearance of cancer and other diseases. It was discovered that the phycocyanin pigment, which I mentioned previously, not only reduces inflammation in the body, but also contributes to blocking the development of tumors and destroying cancer cells.

Next, we will provide details about the 10 health benefits that spirulina can bring to your life.

1. Spirulina Promotes Weight Loss

In general, to reduce body weight, the value of the calories ingested must be lower than the calories burned to obtain energy. Spirulina is rich in nutrients, but has a low caloric content, so by introducing it into your daily diet, you can lose weight without suffering from a nutritional deficit.

2. Improves Gut Health

Due to its structure, made up of cells that do not have hard and fibrous walls, blue-green algae can be easily digested. Animal studies show that seaweed can support gut health as people age. A 2017 study conducted on elderly mice suggests that spirulina can maintain the health of gut bacteria during the aging process.

Despite these benefits, Arthrospira platensis has a low fiber content, so it is very important to include in your diet other healthy foods for the intestine, which are rich in fiber.

3. Spirulina Manages diabetes

Spirulina has shown promise as a way to manage diabetes symptoms. Following a 2018 study, it was found that supplementing the diet with spirulina significantly reduces blood glucose levels, a common problem for patients with type 1 and 2 diabetes. Research results suggest that spirulina supplements benefit people who want to keep their blood sugar control.

During another study, carried out in 2017, researchers administered this type of algae to mice that had type 1 diabetes. As a result, they found a reduction in sugar levels, an increase in insulin concentration and an improvement in liver enzyme markers. The researchers concluded that the antioxidant effect of this superfood can be helpful in the treatment of type 1 diabetes.

4. Lowers Cholesterol

The administration of the spirulina extract also benefits the body in that it can help reduce the level of cholesterol, an unhealthy fat that gradually accumulates in the blood and that specialists associate with heart disease.

A systematic meta-analysis from 2016 suggests that spirulina supplements can have a positive influence on blood lipids (blood fats). Through this study, it was discovered that blue-green algae significantly reduces the level of total cholesterol, decreasing LDL (“bad”) cholesterol and, at the same time, increasing the concentration of HDL (“good”).

An older study from 2013 also supports these results. The researchers observed that by administering 1 g of spirulina daily, the study participants managed to reduce their cholesterol level after 3 months.

5. Reduces Blood Pressure

In addition to the fact that spirulina can reduce cholesterol, there is evidence that it can also help in lowering blood pressure. A small-scale study in 2016 showed that, administered regularly for 3 months, Arthrospira platensis reduced blood pressure, bringing benefits to overweight people who had hypertension.

6. Spirulina Prevents Heart Diseases

Hypertension and high cholesterol levels are associated with cardiovascular diseases. Since spirulina supplements have benefits in both respects, it is believed that this can also contribute to reducing the risk of heart disease.

A 2013 study suggests that blue-green algae may play a role in preventing these conditions, probably due to its antioxidant, anti-inflammatory and cholesterol-lowering effects.

7. Stimulates Metabolism

Spirulina supplements can help improve metabolism. When a person’s metabolic rate increases, they feel more energetic. It can also increase the number of calories that the person burns daily, thus reducing body weight.

All of these benefits were confirmed by a 2014 study that was conducted on a small scale. The participants in the study administered 6 g of spirulina per day, then found favorable metabolic effects, accompanied by weight loss and an improvement in the quality of life. The participants suffered from non-alcoholic fatty liver disease. We hope that in the future, additional research will be carried out on the effects of spirulina on the metabolism of people who do not suffer from this condition.

8. Reduces Allergy Symptoms

People who suffer from allergies to pollen, dust or pet hair, face inflammation of the inner area of ​​the nostrils, a reaction called “allergic rhinitis”. Fortunately, it seems that blue-green algae can bring benefits in such cases as well.

Through a 2013 study, it was observed that spirulina can improve nasal inflammation and reduce the level of histamines in the body. Compared to placebo, blue-green algae actually reduces the symptoms associated with allergic rhinitis, namely:

  • Runny nose
  • Sneezing
  • Nasal congestion
  • Itching

9. Spirulina Fights Toxins

In certain regions of the world, the population is exposed to the risk of poisoning, due to the consumption of contaminated water and other sources of pollution. Early research suggests that spirulina may confer benefits to those affected by these conditions.

Following a study from 2016, it was observed that this superfood has anti-toxic properties, which can counteract the polluting agents that enter the body, including:

  • Arsenic
  • Fluoride
  • Iron
  • Lead
  • Mercury

The authors of the conducted research suggest that spirulina supplements can be useful as an adjuvant in the case of the treatment recommended to combat poisoning with polluting agents.

10. Supports the Nervous System

And the last, but not the least important on the list of benefits, is the fact that Arthrospira platensis can be helpful for good cognitive functioning. In this sense, a scientific paper from 2018 highlighted the potential role that spirulina can play in the treatment of various mood disorders.

The theory from which the respective work started consists in the fact that spirulina is a source of tryptophan, an amino acid that favors the production of serotonin (neurotransmitter), which in turn plays an important role in maintaining mental health.

People suffering from certain mental disorders, such as depression and anxiety, may have low levels of serotonin. Supplementing the diet with products based on tryptophan can help maintain optimal levels of serotonin, thus favoring the functioning of the nervous system.
