Spirulina for weight loss: why and how to use it?


Many people use spirulina to lose weight, without really knowing why it allows you to lose weight, or how to use it to lose weight.

So let’s develop the subject to find out everything about the slimming virtues of this famous seaweed recommended by nutritionists!


Overweight and obesity affect more and more people in France and are becoming a real public health problem. Whether for their health or only from an aesthetic point of view, nearly 75% of French people want to lose weight.

For this, we find diets as varied as each other, while it is enough to adopt a healthy and balanced lifestyle to see the superfluous pounds disappear, except in the case of more important health concerns: disorders of the thyroid, obesity, etc.


As for food, divide your plate in half and put vegetables in one half, separate the other half again in two and put meat or fish in a quarter, and starches in the remaining quarter, you will see, that makes miracles.

In addition to that, get moving, exercise regularly, and apply little tips as we will see in this article on spirulina and weight loss. Because does spirulina make you lose weight?

Yes and no. You cannot lose weight just by consuming these microalgae, however, it can help burn fat indirectly and it works in many ways towards lasting weight loss by helping to control your diet.

Benefits of spirulina for weight loss

It is advisable to consume spirulina to accompany a diet because:

• it acts as an appetite suppressant,

• it is rich in proteins,


• it provides energy and supplements the diet

• it detoxifies the body,

• all for a low-calorie intake.

Natural appetite suppressant

Spirulina contains phenylalanine, an amino acid that acts as an appetite suppressant. By consuming spirulina, we accentuate the feeling of satiety and we, therefore, have less desire to eat.

Once in the intestine, it causes the secretion of a hormone that signals to the brain that the level of satiety has been reached.

Studies have shown a decrease in the amount of food consumed caused by taking phenylalanine before meals by up to 22%.


The action of phenylalanine hydroxylase converts phenylalanine into another amino acid, tyrosine, a precursor of adrenaline, norepinephrine, and melanin.

Therefore, combining phenylalanine with a diet helps reduce moods and motivation drops, while promoting a state of joy, well-being, and pleasure in the brain.

To take advantage of this appetite suppressant action and to optimize it, it is advisable to consume the spirulina powder about 15 to 20 minutes before eating to allow time for the phenylalanine to be digested and to cause the effects.

High protein content

Spirulina is a cyanobacterium made up of up to 70% protein, which makes it a perfect ingredient in a diet.

Indeed, proteins require more energy to be digested by the body than they provide, thus, by producing more efforts to digest them, and the body directly burns more fat and calories.

Let us add that the proteins of spirulina are what are called complete proteins, that is to say, composed of 8 essential amino acids, unique in the world of vegetable proteins. Indeed, the only other sources of complete proteins are all derived from animal products such as meat or eggs.


Thus, spirulina is an ideal dietary supplement for weight loss.

Note that the proteins contained in spirulina, both numerous; of excellent quality, and containing all the essential amino acids, promote the synthesis of keratin, a protein representing 95% of the hair composition, whose role is to protect the hair from external aggressions: pollution, UV, seawater, etc.

Thus, spirulina is beneficial for the hair, allows them to regain their shine and flexibility, whether in treatments or masks.

Stimulating, energizing, and revitalizing effect

Spirulina is known and recognized to stimulate the body and raise the general level of energy in the body, ideal during a slimming diet which can tend to cause slackening.


Food supplements such as spirulina are, in fact, foods that are much richer in minerals, nutrients, vitamins, electrolytes, and phytonutrients than most foods, which makes them unique.

The exceptional nutritional composition of the seaweed helps to fill any deficiencies caused by a poorly calibrated diet, which is unfortunately often the case when you want to lose weight on your own and without professional advice.


It improves the overall state of health and is beneficial for the entire body, which is why it is often advisable to consume spirulina for thyroid problems for example.

With the reserve of vitamins and energy provided by spirulina, you will feel more inclined to move around, to walk, in short: to exercise, which is essential for lasting weight loss.

Some people compare spirulina to coffee, tea, and other exciting drinks for its stimulating effects, with the difference that spirulina increases vitality quickly, but especially in the long term.

Detoxifying action

It is more difficult to lose weight with an organism whose cells are loaded with toxins.

Intoxication of cells prevents the proper function of the organs they make up: gall bladder, pancreas, liver, intestine, nervous system, etc.

As the body does not function optimally, this will create an imbalance and will promote weight gain.


One of the properties of spirulina is its ability to detoxify the body in depth, in particular thanks to its phycocyanin content, the natural pigment that gives the algae color. Phycocyanin works on two fronts:

• it is a powerful detoxifier: it allows deep cleansing of the cells

• it is a powerful regenerator: it activates the cellular regeneration of tissues

Spirulina will therefore help cleanse and purify the whole body, promoting the elimination and loss of extra pounds. It is also one of the reasons for the action of spirulina on acne and skin problems.

Low in calories

Yes, the principle of losing weight is still bringing fewer calories to the body than it burns, and this is the case with spirulina.

Despite its nutritional richness, spirulina is low in calories: 1 teaspoon, or about the daily dose during a cure, contains only 20 calories.


Thus, by taking spirulina, we will meet several nutritional needs, without increasing its calorie rate.

How to use spirulina for weight loss

To take full advantage of its nutritional composition, you must consume cold spirulina, because the nutritional value of food decreases with heat.

It has a strong flavor, so it is rather advisable to combine it with a drink or tasty food: fruit juice, vegetable juice, a smoothie, yogurt, etc.

If you want to use it for its appetite suppressant properties, it is recommended to take a dose of spirulina about 15 minutes before the meal.

If you want to play sports and increase your performance to lose weight and lose weight, it is recommended to take a dose of spirulina about 30 minutes before exercise.

Dosage of spirulina for weight loss

The classic dosage is to consume between 2 and 5 g of spirulina powder per day (approximately 1 teaspoon), starting with a dose of 1 g per day during the first week, then gradually increasing the doses by 0, 5 g every 5 days.


It is possible to take this daily dose several times, for example: if you take 4 g of spirulina, you can take 2 g before lunch and 2 g before dinner.

Spirulina is only effective if taken as a daily cure for several weeks, between 4 and 6 weeks, followed by a break as long as the cure. It is not recommended to do more than 3 cures per year.

The general recommendation is not to exceed 6 g and the first effects of spirulina are felt from 800 mg.

We have dedicated a special article detailing what are the contraindications and side effects of spirulina.
