Spirulina is a blue-green alga that can be used as a nutritional supplement. It’s usually offered as a dark-green powder. Spirulina powder is considered a superfood because of its nutritional value and potential health advantages. Spirulina is high in protein and vitamins, making it an excellent dietary supplement. According to research, it possesses antioxidant and anti-inflammatory characteristics and can assist in regulating the immune system. This article highlights the significant health benefits of using spirulina powder.
Nutritional Value of Spirulina Powder
Spirulina powder is an excellent source of vitamin A, E, and K. It also contains fatty acids (DHA, EPA), beta carotene, phycocyanin (A pigment with antioxidant effects), and minerals. It is also a good source of protein. According to USDA, one table teaspoon of spirulina powder has the following nutrients:
- Energy-20 calories
- Protein-4.0 gram
- Fat-0.5 gram
- Carbohydrates-1.5 gram
- Fibers-9.3 gram
- Potassium-95 milligrams
- Iron-2 milligrams
- Vitamin C-1 milligram
- Salt-0.18 gram
It also has a good amount of magnesium, potassium and manganese, as well as trace levels of nearly every other nutrient.
Health Benefits of using Spirulina Powder
Spirulina has been linked to various health benefits, including cardiovascular health, blood pressure control, and weight loss.
It is high in antioxidants
Oxidation is a constant inflammatory and cell-damaging process that can eventually lead to chronic diseases and cancer. Antioxidants abound in spirulina. The dark blue-green color of spirulina is due to one of its pigments, phycocyanin. Phycocyanin is an essential antioxidant and anti-inflammatory product. This pigment helps prevent inflammation, and reduce oxidative stress.
Spirulina powder boosts cardiovascular health
According to a study conducted in 2018, spirulina supplements can considerably lower total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides. For 48 weeks, the participants consumed 1 to 19 grams of spirulina each day. According to the researchers, spirulina had a “favorable effect” on certain cardiac parameters .
According to another study, spirulina can improve blood lipid profiles, reduce inflammation and oxidative stress, and protect against cardiovascular disease. 
Spirulina Powder can also help decrease blood pressure. A study discovered that taking 4.5 grams of spirulina powder daily for six weeks reduced systolic and diastolic blood pressure . If you are suffering from high blood pressure, do not hesitate to use spirulina powder.
It can help with diabetes
Spirulina has also been demonstrated to aid in preventing and treating diabetes. According to a study supplementing with spirulina dramatically reduced fasting blood glucose levels of many patients. It has about 4 grams of protein per tablespoon, which is beneficial for blood sugar and diabetic management. It is never advised to start taking spirulina and stop taking any medications. However, if you’re starting to notice signs of insulin resistance, this could be one of several tools in your toolbox.
Using spirulina powder can enhance muscle strength
According to a study published in 2020, adding spirulina to one’s diet can help reduce :
- BMI (body mass index)
- Body fat
- Waist measurement
- Lipids in blood
An explanation for all these effects is that the chemicals in spirulina powder hinder the small intestine from absorbing as much fat. However, more research and clinical trials are needed to validate these advantages.
Final Words about Spirulina Powder
Spirulina consumption has significant risks, despite its many advantages. Spirulina powder also contains anticoagulant (blood-thinning) properties, so anyone who has clotting issues or uses blood-thinner drugs should avoid it. And also includes phenylalanine, an amino acid toxic to people who have the genetic condition of phenylketonuria. When purchasing a supplement, ensure it has been third-party evaluated to guarantee it is safe to consume.
