Spirulina is a microalga that has been found to have powerful nutritional and therapeutic effects. Studies show that this blue-green algae can help with a wide range of issues, from weight loss and blood pressure to cholesterol and heart health. Although it is an excellent source of protein, spirulina is also packed with vitamins, minerals and antioxidants. It also contains phycocyanin, which gives spirulina its color and has been shown to have anti-inflammatory, pain-relief, anti-tumor, and brain-protecting properties.
The Spirulina effect is based on the fact that the algae is an obligate photoautotroph, meaning that it does not need to consume anything other than sunlight for energy. In addition, Spirulina can absorb carbon dioxide, which it reduces to carbohydrates during photosynthesis. It can also assimilate nitrates, which it uses as its main source of nitrogen.
It has been found that spirulina can reduce both LDL-C and VLDL-C, as well as triglycerides and HDL-C in multiple studies of mostly unhealthy populations. It does this by promoting vasodilation and nitric oxide production. In addition, spirulina appears to inhibit platelet adhesion.
Some studies have shown that spirulina can also prevent high blood triglyceride levels after a meal by slowing the absorption of dietary fats. In one study, eating 5 grams of spirulina per day for two weeks reduced post-meal triglyceride levels by 20 percent. Spirulina can also decrease oxidative stress, which contributes to dyslipidemia.
Spirulina may also increase your immune system, which can strengthen your body’s ability to fight off infections. In addition, this organism can improve digestion by stimulating the growth of healthy bacteria in your intestines. It can also help balance your hormones, lower your cholesterol and blood sugar levels and boost your energy.
However, spirulina is not a cure-all, and it should be used in conjunction with a balanced diet and exercise to achieve the best results. For example, if you have high cholesterol or blood pressure, you should not take spirulina supplements alone without first working with your doctor to create an appropriate treatment plan. You should also avoid taking spirulina if you have certain medical conditions, including hypothyroidism or hyperparathyroidism. The excess nutrients in spirulina could negatively affect the function of these glands, leading to fluid retention in the legs, an imbalance in calcium, phosphorus and iodine absorption, weight gain or loss, and other symptoms.
Spirulina is not appropriate for pregnant women or children under the age of 2. It can also cause allergic reactions in some people. If you are allergic to shellfish or seafood, you should also avoid spirulina.
Spirulina can have some side effects, including bloating, stomach upset and allergic reaction in some people. If you experience any of these symptoms, stop taking the supplement and contact your doctor immediately.
