Spirulina is a type of blue-green algae that people can take as a dietary supplement. People consider spirulina a superfood due to its excellent nutritional content and health benefits.
Spirulina has a high protein and vitamin content, which makes it an excellent dietary supplement for people on vegetarian or vegan diets.
Research suggests that spirulina has antioxidant and inflammation-fighting properties, as well as the ability to help regulate the immune system.
Here are some potential health benefits people may get from adding spirulina to their diet:
1. Excellent nutritional profile
Spirulina is high in protein and vitamins.
Consuming spirulina is one way to supplement protein and vitamins in people’s diets without notable side effects.
One tablespoon or 7 grams (g) of dried spirulina contains:
4.02 g of protein
1.67 g of carbohydrate
0.54 g of fat
8 milligrams (mg) of calcium
2 mg of iron
14 mg of magnesium
8 mg of phosphorous
95 mg of potassium
73 mg of sodium
0.7 mg of vitamin C
It also contains thiamin, riboflavin, niacin, folate, and vitamins B-6, A, and K.
Taking spirulina, as part of a balanced diet, may help a person to stay well nourished.
2. Losing weight
People can usually lose weight if they eat fewer calories than they use. Spirulina is a high-nutrient, low-calorie food that contains a lot of nutrition in a small amount of powder. Introducing spirulina to the diet may help people lose weight without losing nutrition.
3. Improving gut health
Spirulina can be digested easily because of its structure where the cells do not have tough, fibrous walls. Spirulina may support gut health as people age, as spirulina may preserve healthy gut bacteria during the aging process.
4. Managing diabetes
Spirulina shows promise as a way to manage the symptoms of diabetes, as spirulina supplementation significantly lowers people’s fasting blood glucose levels.
5. Lowering cholesterol
Studies suggest that spirulina supplements can reduce total cholesterol.
Taking spirulina extract may help to lower cholesterol levels. Cholesterol is an unhealthful fat in a person’s blood that medical experts link to heart disease.
6. Reducing blood pressure
Spirulina may lower cholesterol, and there is also evidence that it could help control a person’s blood pressure.
7. Preventing heart disease
High blood pressure and cholesterol levels are both linked to heart disease, and spiruluna may play a role in preventing heart disease. This might be due to their cholesterol-lowering, anti-inflammatory, and antioxidative effects.
8. Boosting metabolism
Taking spirulina may help boost a person’s metabolism. A higher metabolic rate may make a person feel as if they have more energy. It may also increase the number of calories they burn each day, which may aid weight loss.
9. Reducing allergy symptoms
When a person has allergies to pollen, dust, or pets, the inside of their nose may swell. This reaction is called allergic rhinitis. There is some evidence that spirulina could help improve the symptoms of this condition, including:
10. Antitoxic action
In certain parts of the world, people are at risk of poisoning from contaminated drinking water and other sources of pollutants. Early research suggests that spirulina may offer a way to treat those affected.
11. Supporting mental health
Spirulina could play in treating mood disorders. People with certain mental health conditions, such as depression and anxiety, may have reduced levels of serotonin. Taking spirulina to maintain healthful serotonin levels may play a role in supporting mental wellbeing.
