SPIRULINA Benefits according to Dr. Group, there are literally thousands of different types of algae, but three are by far the most popular: spirulina (the main ingredient in those strikingly blue lattes), AFA, and chlorella. First, the good news on The Big Three: “They all have very high concentrations of nutrients and vitamins, including protein, iron, potassium, zinc, calcium, and B vitamins.”
1. Excellent nutritional profile
SPIRULINA Benefits is after consuming spirulina is one way to supplement protein and vitamins in people’s diets without notable side effects.
SPIRULINA Benefits in One tablespoon or 7 grams (g) of dried spirulina contains:
- 20 calories
- 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. SPIRULINA Benefits in 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.
The results of a 2016 double-blind placebo-controlled trial suggest that spirulina may aid weight management. In the study, people who were overweight and regularly ate spirulina for 3 months showed improved body mass index or BMI.
3. SPIRULINA Benefits in Improving gut health
Spirulina can be digested easily because of its structure where the cells do not have tough, fibrous walls. But can consuming it improve gut health?
More research on humans is needed, but animal studies indicate spirulina may support gut health as people age. A 2017 study on older mice suggests that spirulina may preserve healthy gut bacteria during the aging process.
Spirulina does not contain much fiber, so it is essential to include other gut-healthful, high-fiber foods in the diet.
4. SPIRULINA Benefits in Managing diabetes
Spirulina shows promise as a way to manage the symptoms of diabetes. But more research is needed before doctors can recommend it.
A 2018 review study found that spirulina supplementation significantly lowered people’s fasting blood glucose levels. High fasting blood sugar is a common problem in people with diabetes type 1 and 2. This suggests that spirulina supplements may help people control diabetes.
These results suggest that spirulina shows promise as a food to support type 2 diabetes management.
A 2017 animal study supports the idea that spirulina may help manage diabetes. In this study, the researchers gave mice with type 1 diabetes spirulina extract orally. As a result, the mice showed:
- lower blood sugar
- higher insulin levels
- improved liver enzyme markers
The researchers note that the antioxidant effect of spirulina may be helpful in treating type 1 diabetes.
5. Lowering 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.
A 2016 systematic review and meta-analysis suggests that taking spirulina supplements may have a positive impact on blood lipids, which are fats in the blood. In the study, spirulina was found to significantly reduce total cholesterol and lower LDL — “bad” — cholesterol while increasing HDL — “good” — cholesterol.
A 2013 study also supports this health claim. Researchers found that taking 1 g of spirulina every day reduced participant’s total cholesterol after 3 months.
6. Reducing blood pressure
As discussed above, spirulina may lower cholesterol, and there is also evidence that it could help control a person’s blood pressure.
A small-scale 2016 study found that eating spirulina regularly for 3 months reduced people’s blood pressure when they were overweight and had hypertension.
7. Preventing heart disease
High blood pressure and cholesterol levels are both linked to heart disease. As spirulina may reduce both of these risk factors, is it possible that it could help prevent heart disease?
A 2013 review suggests that these blue-green algae 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.
In a small-scale 2014 study, people who took 6 g of spirulina a day experienced beneficial metabolic effects, alongside weight loss and better health-related quality of life.
The people in this study had non-alcoholic fatty liver disease, and so more research is needed to see if spirulina may boost metabolism in others without this condition.
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.
A 2013 study states that spirulina can relieve nasal inflammation and reduce histamine in the body. Compared to a placebo, it may reduce the symptoms of allergic rhinitis, including:
- runny nose
- nasal congestion
A 2011 review notes that there is a reasonable amount of evidence for the positive effects of spirulina on allergic rhinitis, but that larger trials are needed before researchers know the true impact.
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.
A later 2016 review found that spirulina had antitoxic properties that could counteract pollutants in the body, including:
The authors of the review suggest that spirulina could be a useful substance to use alongside clinical treatment of pollutant poisoning.
11. Supporting mental health
A 2018 paper highlights the potential role that spirulina could play in treating mood disorders.
The theory is that spirulina is a source of tryptophan. Tryptophan is an amino acid that supports serotonin production. Serotonin plays an important role in mental health.
People with certain mental health conditions, such as depression and anxiety, may have reduced levels of serotonin. Taking tryptophan supplements to maintain healthful serotonin levels may play a role in supporting mental wellbeing.
Researchers need to conduct more clinical trials before they know the true role of spirulina in supporting mental health.
Are there interactions or risks?
The United States Food and Drug Administration (FDA) does not regulate spirulina, but a 2014 review notes that spirulina is well-tolerated by most people, so does not cause any significant side effects.
It is a good idea to check any drug interactions with a doctor before taking a new dietary supplement, including spirulina.
How to include spirulina in the diet
Spirulina is available in powder or tablet form.
As a powder, people can:
- add it to smoothies, which gives the drink a green color
- sprinkle spirulina powder on salads or in soups
- mix it into energy balls, along with other healthful ingredients
- stir a tablespoon into fruit or vegetable juices
People can also take spirulina as a dietary supplement in tablet form.
People can buy dried spirulina from health food stores or online stores. Spirulina tablets are also available in health food stores, drug stores, and online.
Initial research suggests taking spirulina may improve the following:
- weight loss
- gut health
- diabetes management
- blood pressure
- risk of heart disease
- metabolic rate
- allergy symptoms
- mental health
Alongside zinc, spirulina shows promise as a treatment for chronic arsenic poisoning.
More research is needed before doctors can recommend spirulina for the treatment of any health condition.
