Buying Guide: Everything You Need to Know About Spirulina

Spirulina is unquestionably a superfood with tremendous potential in improving health. However, before buying it, you must have all the information available to make sure that this is the right supplement for you. You will thus know how to take full advantage of all its properties.

The Best Spirulina

We hope to answer all of your questions regarding spirulina supplementation in the following sections.

What Exactly is Spirulina?

Spirulina is generally considered to be algae because it thrives in water, can photosynthesize, and, when bundled together, forms blue-green filaments.

However, the supplement we know as Spirulina is a photosynthetic spiral-shaped cyanobacterium. As it grows and attains sufficient density, it is dried and pulverized to be consumed as a powder or administered as capsules or tablets.

What Makes Spirulina so Good for Our Health?

Firstly, spirulina has an excellent nutritional profile, including:

  • 57-60% of its dry weight is protein, containing all the essential amino acids – those that humans get exclusively from food or supplements, as our bodies cannot synthesize them.
  • About 20% complex carbohydrates.
  • Between 5% and 7% fat, with a predominance of omega 3 and omega 6.
  • It contains provitamin A (beta-carotene), vitamins B1, B2, B3, B5, B6, and B9 (folic acid) and vitamin E (tocopherol).
  • It contains iron, zinc, magnesium, manganese, potassium, selenium, calcium, and sodium.

Did you know that a historical UNESCO publication (1969) defined spirulina as “an alga three times more nutritious than a good steak”?

What Are the Other Benefits of Spirulina?

In addition to its nutritional contribution, spirulina provides other benefits and can be a real ally in improving health and well-being. Therefore, it is considered to be a superfood with the following properties:

  • Energizing and revitalizing
  • Immunostimulant
  • Antioxidant
  • Detoxifying
  • Satiating and appetite suppressant
  • Hypoglycemic (decrease in fasting and after meals blood sugar)

Why Are We Talking So Much About Spirulina?

Although this is an ancient food, the interest of Western health professionals and researchers for its beneficial health properties only emerged a few decades ago.

One of the first cases of recognition of the excellent health effects of this microalgae dates back to 1974 when the United Nations (UN) World Food Conference declared it “the food of the future.”


Why is it Recommended to Consume Spirulina?

People who have consumed this supplement for the long term attest to its benefits:

  • The increased energy level and a revitalizing feeling. Less physical and mental fatigue.
  • Less appetite and a feeling of fullness, a feeling of being satisfied for several hours after a meal.
  • Reduction in blood cholesterol and triglyceride levels.
  • Improves insulin resistance and lowers blood sugar.
  • Strengthening the immune system.

Why is it Recommended to Supplement Spirulina to fight Against Fatigue?

Spirulina is a concentrate of vitamins and minerals. Many of them are involved in metabolic reactions in our body to obtain energy from nutrients.

As fatigue can be the result of a deficiency of vitamins and minerals involved in the transformation of energy, this supplement ensures that the body has the necessary nutrients to convert them into energy.

On the other hand, this microalgae is very effective in preventing and treating anemia, by providing a significant amount of iron and folic acid. These two nutrients are essential for the production of red blood cells in the bone marrow.

Supplement Spirulina

Is it True that Spirulina is an Almost Essential Supplement for Vegans?

In reality, a supplement, no matter how good, is not a substitute for a balanced diet. Therefore, although spirulina is a great ally in improving nutritional intake in vegans, the nutrition of any person – vegan or not – should be carefully planned and supervised by a nutritional professional.

However, this microalgae is an important source of protein for vegans, being proteins of high biological value that contain essential amino acids that the human body cannot produce on its own. In addition, it is rich in iron, zinc, and folic acid, nutrients that are often lacking in the vegan diet.

That said, vegans can significantly improve their nutritional status by pairing this supplement with a balanced diet.

Is Spirulina a Real Source of Vitamin B12?

You will probably read the nutritional labels of spirulina supplements that contain a considerable amount of vitamin B12. Some authors have even mentioned algae as a plant source of this nutrient. The reality is that this information is false and risky.

Spirulina contains a false vitamin B12, which is non-functional. In other words, it does not fulfill the role that real vitamin B12 plays in the body.

The risk is that many vegans believe that by taking spirulina (or other algae) they can meet their needs for this vitamin and thus lead to deficiency.

Is it Advisable to Consume Spirulina to Reduce Cholesterol and Triglycerides?

The lipid-lowering effect of spirulina is undoubtedly one of the most significant benefits this supplement can provide. This is possible thanks to the content of omega 3, omega 6, and soluble fiber.

Numerous scientific research confirms the effectiveness of spirulina in reducing total cholesterol, LDL cholesterol (“bad cholesterol”) and triglycerides in the blood. According to the World Health Organization, this lowers the risk of developing cardiovascular disease, the leading cause of death worldwide.

What Makes Spirulina an Antioxidant Food?

The beta-carotene, vitamin E, and chlorophyll contained in spirulina have antioxidant effects, which means they block free radicals that are responsible for oxidative damage to cells.

Cardiovascular disease, cancer, fibromyalgia, and neurodegenerative diseases (Alzheimer’s disease, dementia, Parkinson’s disease) are pathologies caused by oxidative stress, hence the importance of supplementing spirulina to prevent these conditions.

Did you know that oxidative stress accelerates aging? If you want to live a long life and get older in a healthy way, then consider spirulina supplements.

Are There Any Contraindications to The Use of Spirulina Supplements?

Spirulina supplements are generally safe for the healthy adult population. They are unlikely to produce any side effects and there are no known interactions with the drugs.

Regardless, the following categories of people should consult a doctor before consuming it to prevent risks and complications:

Why is it Important Not to Exceed the Recommended Daily dose for Spirulina Supplements?

As a general rule, the recommended dose of spirulina powder is 2-3 grams per day, and in the case of tablets, 4-6 units per day.

It is important not to exceed the amounts mentioned above, as some nutrients, such as iron and vitamin E, accumulate in the body and can cause excess leading to disease.

Nutritionist and dietitian

“Excess iron is linked to gastrointestinal symptoms and heart problems, while hypervitaminosis E can cause changes in blood clotting.”

How to Take Spirulina to Promote Weight Loss?

To take full advantage of its satiating powered, and appetite suppressant effect, it is advisable to take the supplement 15 to 30 minutes before meals, along with plenty of water.

The mucilages in spirulina absorb water and gel in the stomach. This gel stays in the digestive tract for several hours, prolongs the feeling of fullness, and controls appetite. In this way, less food is consumed throughout the day, which promotes weight loss.

What Types of Spirulina Supplements Are Available and Which One is Right for Me?

Spirulina supplements can be divided into two major groups: powder and tablets. In the rest of the article, we will develop the characteristics of each of them, as well as their advantages and disadvantages.

Types of Spirulina Supplements

Spirulina Powder

Spirulina powder is packaged in bags or jars, the content of which generally varies between 100 and 1000 grams. It is advisable to consume 2 to 3 grams per day, mixed in water, fruit juices, smoothies, shakes, bowls of smoothies, yogurts, dressings, soups, etc.
To choose this type of powdered supplement, it is essential to appreciate the unique flavor of spirulina; otherwise, the intake will be tricky.

Spirulina in Tablets

The supplement in tablet (or capsule) form consists of spirulina powder mixed with a minimal amount of magnesium stearate, hypromellose, or silica. It has a mild taste, and you just need to take it with plenty of water. This form is easy to store and transport.
The calorie intake of the tablet supplement, like the powder one, is negligible. Regarding the nutritional composition, there is no significant difference between the two forms. In contrast, tablets and capsules generally involve more digestive work than powder.

This form of supplement is still the ideal option for those who do not like the taste of spirulina. Also, if you are used to eating meals outside, the tablets and capsules will be easier to carry.

Purchase Criteria

Once you have decided to improve your nutritional status and, more generally, your health with spirulina, there are some characteristics to consider to choose the best alternative for you.


Spirulina has an intense and distinctive flavor, very noticeable in the powdered supplement. So if you don’t like the taste, it is better to go for the tablets or capsules, which have a lighter feeling.
If this is the first time you have purchased a spirulina supplement and you want to try its powder version, we recommend that you go for a small container, such as 100 grams.


Tablets and capsules are much more convenient to take, store and transport, while the powder version should be mixed with water or another liquid (soups, juices, smoothies, vegetable milk, etc.).


The best way to compare the cost of supplements is to divide the price by the number of doses in the package. In general, spirulina powder is cheaper than tablets and just as effective.

Purchase Criteria Spirulina


Certification is a fundamental point because spirulina must be produced in an ecological way, and with the most excellent care. It can be easily contaminated with toxic and heavy metals (lead, mercury, arsenic, cadmium) if these substances are present in the culture medium.

Besides, vegans should ensure that the excipients in tablets and capsules are 100% herbal.

Presence of Gluten, Lactose and Allergens

Since spirulina is naturally gluten, lactose, and allergen-free, it should not contain any of these substances unless it has been contaminated during processing or packaging.


In this article, we have introduced you to the benefits and properties of spirulina, the different supplements available, and the characteristics of each. Our goal is to provide you with quality information so that you can make the best decision for your health.
