What is Spirulina?

Spirulina is a kind of blue-green algae that can use as a dietary supplement. However, people apprise spirulina as a superfood due to its better nutritional content and health benefits.

Spirulina has a greater amount of protein and vitamin content, which builds it a better dietary supplement for people on vegetarian or vegan diets. Some study has suggested that spirulina antioxidant and inflammation-dealing properties, as well as the ability to support balance the immune system.

However, there are some potential health benefits people may obtain from adding spirulina to their diet.

1. Excellent nutritional profile

However, absorbing spirulina is one step to supplement protein and vitamins in people’s diets without remarkable side effects. One tablespoon or 7 grams of dried spirulina may hold:-

  • 20 calories
  • 4.02 grams of protein
  • 1.67 grams of carbohydrate
  • 0.54 grams of fat
  • 8 milligrams of calcium
  • 2 milligrams of iron
  • 14 milligrams of magnesium
  • 8 milligrams of phosphorus
  • 95 milligrams of potassium
  • 73 milligrams of sodium
  • 0.7 milligrams of vitamin C

However, it may also hold thiamin, riboflavin, niacin, folate, and vitamins B-6, A, and K. Using spirulina as part of a balanced diet may support a person to stay well-nourished.

2. Losing weight

People can normally reduce weight if they eat lower calories than they use. However, spirulina is a great-protein low-calorie food that holds severe nutrition in a small amount of powder. Introducing spirulina to the diet may support severe people reduce weight without reducing nutrition.

However, the outcomes of a 2016 double-blind placebo-managed trial advise that spirulina may aid weight management. In the survey, people who have to be overweight and continually ate spirulina for 3 months exhibited increased body mass index or BMI.

3. Improving gut health

Spirulina can be accumulated easily because of its structure, where the cells do not have hard, fibrous walls. But can absorbing it build gut health?

A severe study on humans is required, but animal surveys indicate spirulina may help gut health as people age. A 2017 study on older mice advises that spirulina may protect healthy gut bacteria throughout the aging process.

4. Managing diabetes

Spirulina shows promise as a step to control the signs and symptoms of diabetes. But severe research is required before health consultants can recommend it.

A 2018 review study established that spirulina supplementation significantly fewer people’s fasting blood glucose levels. High fasting blood sugar is a familiar issue in people with diabetes type 1 and 2. However, this may suggest spirulina supplements may support people manage diabetes.

However, these outcomes suggest that spirulina shows promise as a food to help type 2 diabetes management.

A 2017 animal survey helps the idea that spirulina may support control diabetes. In this survey, the researchers gave mice with type 1 diabetes spirulina to take out orally. As a  result, the mice showed:-

  • Low blood sugar
  • Greater insulin levels
  • Raised liver enzyme markers

5. Lowering cholesterol

Taking spirulina extract may support lower cholesterol levels. Cholesterol is a harmful fat in a person’s blood that medical specialists connected to heart disease.

A 2016 systematic review and meta-analysis advises that using spirulina supplements may have a positive (+) impact on blood lipids, which are fats in the blood. In the survey, spirulina was established to significantly decrease total cholesterol and lower LDL “bad” cholesterol while raising HDL “good” cholesterol.

6. Reducing blood pressure

As discussed above, spirulina may bottom above cholesterol, and there is also proof that it could support manage a person’s blood pressure.

A small-scale 2016 study established that eating spirulina regularly for 3 months decreased people’s blood pressure when they were overweight and had dehydration.

7. Preventing heart disease

However, high blood pressure and cholesterol levels are both connected to heart disease. As spirulina may decrease both of these risk factors, is it viable that it could support stop heart disease?

A 2013 review advises that these blue-green algae may play a vital role in stopping heart disease. However, this might be due to their cholesterol-bottoming, anti-inflammatory, and antioxidative effects.

8. Boosting metabolism

Taking spirulina may support increase a person’s metabolism. However, a greater metabolic rate may build a person feel as if they have severe energy. However, it may also raise the severe calories they burn each day, which may aid in weight loss.

In a small-scale 2014 study, people who grip 6 grams of spirulina a day felt advantageous metabolic effects, alongside weight loss and excellent health-linked quality of life.

9. Reducing allergy symptoms

When a person has allergies to pollen, dust, or pets, the inner side of their nose may swell. However, this reaction is known as allergic rhinitis. However, there is some proof that spirulina could support build the symptoms of this situation.

A 2013 study states that spirulina can manage nasal inflammation and decrease histamine in the body. Compared to a placebo, it may decrease the symptoms of allergic rhinitis, including:-

  • Runny nose
  • Sneezing
  • Nasal congestion
  • Itching

10. Antitoxic action

In certain parts of the world, people are at risk of poisoning by polluted drinking water and other sources of pollutants. However, early research advises that spirulina may offer a way to cure those affected.

A later 2016 review established that spirulina had antitoxic materials that could counteract particles in the body, including:-

  • Arsenic
  • Flouride
  • Iron
  • Lead
  • Mercury
