Discover the Power of Spirulina: A Natural Superfood for Optimal Wellness

Spirulina is a superfood for everyone's health! Nutrient-rich algae with a wide range of health benefits.


Spirulina was once a little-known superfood. But in recent years, because more and more research has been conducted on the potential benefits of this unique algae, it has started gaining increasing popularity as a natural way to support optimal wellness. It is a rich source of protein, vitamins, minerals, and antioxidants, and has been shown to have a number of health-promoting properties.

Today, spirulina can be found in a variety of forms, including capsules, tablets, and powder; it is commonly added to smoothies, protein bars, and other health products.

Spirulina – Nutrition facts

Spirulina has high energy value, mega-high protein, a small amount of fat, also high carbs and a small amount of sugar. There is also a small amount of fibre and a very low glycemic index which is good for blood glucose levels.


Spirulina – Good news

Spirulina is associated with many health benefits, from normalizing your blood pressure to weight loss.

1Can support blood sugar control

According to a review of eight studies, spirulina supplementation in doses ranging from 0.8-8 g daily could significantly reduce fasting blood sugar levels in people with type 2 diabetes

2May reduce blood pressure

One review of five studies showed that taking 4.5g a day for 6 weeks has a positive effect on reducing both systolic and diastolic blood pressure, especially in overweight patients.

3Can have anti-cancer properties

The effects of spirulina on oral cancer or oral cavity cancer have been particularly well-studied.

In fact, several studies have shown that taking spirulina may be useful in treating oral submucosal fibrosis (AMF), a type of precancerous lesion in the mouth.

4Takes care of your heart health

Spirulina can lower total cholesterol, LDL (bad) cholesterol and triglycerides, and raise HDL (good) cholesterol.

Triglycerides and cholesterol are both types of fats that are found in the body. These types of fats are often measured together as part of a lipid panel, a blood test used to assess the risk of heart disease. Elevated triglyceride and LDL cholesterol levels can increase the risk of heart disease and other health problems.

Managing triglycerides and cholesterol levels is important for overall health and well-being. This may involve making lifestyle changes such as eating a healthy diet, getting regular physical activity, and limiting alcohol intake. In some cases, medication may be necessary to lower high levels of triglycerides or cholesterol.

5Boasts powerful antioxidant and anti-inflammatory properties

Spirulina is a fantastic source of antioxidants that can protect against oxidative damage. Its main active ingredient is called phycocyanin, which is an antioxidant and gives spirulina its unique blue-green colour. Phycocyanin can fight free radicals and block the production of molecules that promote inflammation, providing an impressive antioxidant and anti-inflammatory effect.

6Promotes weight loss

The 2020 review concludes that including spirulina in the diet can help reduce:

  • body mass index (BMI)

  • excess body fat

  • waist size

  • appetite

  • blood lipids

Spirulina also has an extremely high protein content, as 60-70% of its weight is made of proteins and amino acids. This makes it a great product for weight loss, as many diets are based on consuming fewer carbohydrates and more protein. After all, a protein-rich diet helps you stay satisfied longer, as your body needs more time to process the protein. Moreover, protein-rich foods help our bodies build muscle mass, making us stronger.

7Can increase your endurance

When it comes to the benefits of exercise and fitness, spirulina can help increase muscle strength, endurance and performance. In one study men who took 6 grams of spirulina daily for four weeks exercised longer without fatigue than those who did not take spirulina. Although the mechanism of the ergogenic effect of spirulina is difficult to determine, the most plausible explanation is fat oxidation, whose rate increased significantly (15.8%) during the 2-hour trial in people taking spirulina.

8Helps improve mental health

Spirulina can also support mental health – even play a role in treating mood disorders. This superfood has been found to contain tryptophan, an amino acid that increases the amount of serotonin in the brain and may be useful for preventing and controlling certain mental disorders such as depression, bipolar disorder, eating disorders and anxiety disorders, schizophrenia etc.

9An affordable source of protein and other nutrients

The cost of spirulina can vary depending on a number of factors, such as the form in which it is sold (e.g. powder, tablets, capsules), the brand, and the place of purchase. In general, spirulina is considered to be a relatively affordable supplement.

For example, Holland & Barrett Spirulina 60 Tablets 500mg cost £6.99.

Naturya Organic Spirulina Powder 100g will cost you £5.99

Green Origins Spirulina Tablets 500mg 180 Tablets cost £14.99

Spirulina – Bad news

Despite all the benefits of spirulina, there are some risks associated with its consumption.

May harm the liver

During the growth cycle of the algae in the marine environment, they can accumulate heavy metals, harmful bacteria or microcystins, which can be harmful to the liver.

Do not combine with blood thinners

Spirulina also has anticoagulant (or blood-thinning) properties, so people with clotting disorders or who take blood-thinning medication should consume it with caution.

Not recommended for people with autoimmune diseases

Spirulina also contains phenylalanine, an amino acid that is harmful to people with the genetic disease phenylketonuria (PKU). People with autoimmune disorders may also experience negative reactions to the algae.
