Regular physical activity can help athletes and people recover more quickly, have more endurance, and lessen muscular tiredness. Spirulina pills were found to improve an athlete’s performance during an arm cycling workout by raising oxygen levels, according to a study published in the European Journal of Applied Physiology.

5. Heart health

By lowering blood pressure and cholesterol, spirulina may help lessen the risk of cardiovascular illnesses. It has been demonstrated to raise HDL (good cholesterol) and lower triglycerides and LDL (bad cholesterol). According to a study of five research papers published in Nutrients, individuals with high blood pressure can benefit from consuming up to 8 g of spirulina daily.

6. Blood sugar control

Those who already have diabetes or are at risk of getting it may benefit from spirulina’s ability to control blood sugar levels. According to animal studies that were published in Cambridge Open Access, spirulina affects insulin secretion and may have a hypoglycemic effect. According to a different study that was published in the Journal of Diabetes and Metabolic Disorders, patients with type 2 diabetes may benefit from taking 0.8–8g of spirulina to lower their fasting blood sugar levels.

7. Anaemia treatment

Anaemia can cause a great deal of fatigue, but it can be prevented with the help of spirulina. According to a study that was published in the International Journal of Caring, spirulina can assist pregnant women manage their anemia during the second trimester. Iron deficiency in young children can also be treated with it.

Benefits of Spirulina

Danger of Spirulina!

Although there are many advantages to spirulina, there are also some dangers.

1. Contamination

Spirulina may contain toxins like heavy metals (such as lead, mercury, and arsenic), dangerous microorganisms, or microcystins if it is collected from contaminated waterways or handled incorrectly. In addition to numerous health problems, these pollutants can harm the liver.

2. Allergic reactions

Another uncommon side effect of spirulina is that some people may have allergic reactions to it, which can show up as respiratory problems, skin rashes, swelling, or itching. Starting with a little dose is crucial in order to check for any negative responses.

3. Digestive issues

Some people may experience mild digestive problems, including nausea, bloating, diarrhea, or cramping in their stomachs, as a result of consuming spirulina. Starting with a smaller dose and progressively increasing it will help control these symptoms, which are typically moderate.

4. Interference with medications

Certain medications, especially immunosuppressive ones taken by people with autoimmune illnesses or organ transplants, may interact with spirulina. Because of its high vitamin K content, it can also impact how well anticoagulants (blood thinners) work.

What Does Spirulina Do to The Body?

Spirulina is a concentrated supply of nutrients that support a number of body functions, adding to general health and well-being. Its high protein and vitamin B content, which are necessary for energy generation, raise energy levels. The anti-inflammatory and antioxidant substances boost the immune system, shield cells from harm, and encourage normal aging. Furthermore, spirulina helps the body rid itself of toxins and heavy metals by binding to them, according to Veena. Additionally, it helps to enhance digestion and nutrition absorption by encouraging the growth of good gut flora.

Can You Take Spirulina Every Day?

It is possible to include spirulina in a balanced diet and take it every day. Veena states that although the suggested dosage varies, the usual range is 1 to 3 grams daily. To monitor any negative responses, it’s crucial to begin with a smaller dose and progressively raise it as tolerated. Consistent nutrient intake and continuous health advantages can be achieved by daily ingestion.

Who Should Not Take Spirulina?

Some people should stay away from spirulina. These consist of:

  • People who suffer from autoimmune disorders: Spirulina has the ability to boost the immune system, which may make symptoms worse for those who have lupus, rheumatoid arthritis, multiple sclerosis, or other autoimmune diseases.
  • People with Phenylketonuria (PKU): People with PKU are unable to effectively metabolize phenylalanine, which is found in spirulina.
  • Women Who Are Pregnant or Nursing: Spirulina should not be consumed by pregnant or nursing women unless a healthcare professional recommends it, as there is not enough evidence to support its safety.
  • Individuals with Iodine or Seafood Allergies: Because spirulina may cause allergic reactions, people with iodine or seafood allergies should stay away from it.
  • Those on Specific Medication: Because spirulina can interact with immunosuppressive medications and anticoagulants, those on these prescriptions should speak with their doctor before taking it.

How to Use Blue Spirulina Safely?

Precautions

Keep the following in mind while thinking about using spirulina:

  • Spirulina’s safety for expectant or nursing mothers has not been proven. Before taking spirulina, consult your doctor if you are nursing a baby, intend to become pregnant, or are already pregnant.
  • Spirulina’s safety in youngsters has not been shown. Before giving your child spirulina, please consult their pediatrician.
  • Lake-grown spirulina can occasionally be tainted by lead, other heavy metals, or pollutants present in contaminated water, such as microcystins in the algae.

Spirulina may also need to be avoided by those with certain medical diagnoses, such as autoimmune diseases like multiple sclerosis and lupus. Phenylketonuria (PKU) and maple syrup urine disease (MSUD) are two other situations where spirulina may need to be avoided. These ailments impact how the body processes proteins or amino acids.

Interactions

When consuming spirulina, keep the following interactions in mind:

  • Blood thinners: Each gram of spirulina contains a trace amount of vitamin K (0.26 micrograms). 20 Theoretically, taking a lot of spirulina may affect how some medications, such as Jantoven (warfarin), thin the blood.
  • Medication for diabetes: Spirulina and metformin, a drug used to decrease blood sugar in patients with type 2 diabetes, may have synergistic effects. Twelve When using spirulina with diabetes drugs, care should be taken to avoid lowering blood sugar too much, which could lead to issues.
  • Immune system medications: methotrexate, etanercept (Enbrel), and adalimumab (Humira) may interact with spirulina, though there is little data on this.
