How to use spirulina against cholesterol and triglycerides

Published by

Does spirulina act on cholesterol and triglyceride levels, and if so how to use it?

Spirulina has always been used as a superfood, and its exceptional composition would be beneficial in the fight against cholesterol.

Is it effective on bad cholesterol? What about triglycerides? If so, how can you use it to lower your cholesterol level? Let’s see this together.

NB: Discover our spirulina of French origin!

What is cholesterol?

We talk about good and bad cholesterol, HDL, and LDL, let’s quickly explain this to better understand.


Types of cholesterol

Cholesterol is transported from the liver to other cells in the body, via LDL lipoproteins.

When we talk about LDL-C and HDL-C, we are therefore not talking about cholesterol, but lipoproteins whose role is to transport cholesterol molecules.

There is, therefore, no such thing as “good cholesterol” or “bad cholesterol”, but good or bad modes of cholesterol transport.

When we talk about LDL Cholesterol, called “bad cholesterol”, it is a poorly transported cholesterol molecule. This is because LDL-C can “deposit” cholesterol, which will build up in the arteries.

While when we speak of HDL Cholesterol, said “good cholesterol”, it is a molecule of well-transported cholesterol.

Indeed, HDL-C does not “deposit” cholesterol in the arteries, but on the contrary, “recover” the excess to eliminate it.


The role of cholesterol

Cholesterol is not used as fuel by the body, but plays an important role as a dietary lipid, serving as a component in the structure of bile salts, vitamin D, and steroid hormones (estrogens, progesterone, testosterone, cortisol, aldosterone, etc.).

It is also an essential element of the plasma membranes of cells and has many other functions in the body, so it is necessary for proper metabolic function but in reasonable doses.

What about triglycerides?

Triglycerides are lipids that allow the storage of fatty acids in adipose tissue. High triglyceride levels can also increase the risk of cardiovascular disease and lead to other illnesses.

In general, alcohol, sugars, and excess weight increase the level of triglycerides in the blood. Triglycerides mainly come from sugars and not fat as is often thought.

The causes and consequences of high cholesterol

The causes are multiple and are essentially linked to lifestyle: food that is too rich, too sweet, too salty, stress, alcohol, tobacco, lack of exercise, etc.

One of the risk factors for developing coronary heart disease is excess cholesterol in the blood.


The accumulation of cholesterol in the blood causes it to be deposited on the internal walls of the arteries: this is atherosclerosis. Over time, the vessels harden: this is arteriosclerosis.

Over time, the diameter of the arteries decreases, sometimes they even become blocked altogether, with all the ailments that this causes on the cardiovascular system: infarction, thrombosis, arthritis, and all cardiovascular diseases.

It is the leading cause of death in the West.

How does spirulina lower your cholesterol level?

The seaweed and its exceptional composition work wonders, especially spirulina for diets or spirulina for the thyroid.

Spirulina’s action on cholesterol is attributed to its high level of gamma-linolenic acid, otherwise known as omega-6.

After reviewing the scientific data, the European health authorities (EFSA, European Food Safety Authority, and the European Commission) have found that products that contain linoleic acid can claim to help maintain normal blood cholesterol levels.


Gamma-linolenic acid also allows the synthesis of EPA (eicosapentaenoic acid), making it possible to decrease the concentrations of triglycerides in the blood.

Spirulina triggers the stimulation of an enzyme, lipoprotein lipase, a key enzyme in the metabolism of triglycerides and lipoproteins.


For some, the action of spirulina on cholesterol and triglycerides comes from the high content of spirulina in chlorophyll-a, polyunsaturated fatty acids, fibers, and nicotinic acid, while having a very low ratio between lysine and arginine (0.67).

Studies previously conducted on rats, then conducted on humans at Tokai University, Japan, have confirmed that even a relatively low dose of daily spirulina lowers “bad” cholesterol, as well as an increase in “bad” cholesterol. good cholesterol ”.

Another study, conducted in Germany, initially planned to study the slimming effects of spirulina, showed a decrease in cholesterol in those who had taken spirulina.

The action of omega-6 is also one of the causes of the effects of spirulina on the skin.


How to use spirulina to lower your cholesterol level?

According to studies, the intake of spirulina for cholesterol must be regular. If it stops or is not regular, cholesterol levels return to their original values.

This article is for informational purposes only, consult your doctor before taking anything and embarking on a cure. For more details, see our article on how to use spirulina.

How to use it?

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 better to pair it with a drink or tasty food.

Sprinkle spirulina on food, in fruit juice, vegetable juice, soups, soups, in a smoothie, yogurt, flaxseed or chia pudding, etc., but not in a hot drink!

Several other spices such as turmeric and cinnamon are also allies against “bad” cholesterol. It would be possible to combine them to increase the effect.


For what dosage?

In reality, there is not a precise dosage for spirulina, given that it is a food and not a medicine, but there are recommendations.

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.

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. Most cholesterol studies have been done with doses of 4 to 5 g of spirulina.

Contraindications and adverse effects

We have dedicated a special article detailing what are the unwanted effects of spirulina.

Remember that there is no danger in consuming spirulina if you follow the advice given in the paragraph “For what dosage? », And if you are not one of the people to whom spirulina is prohibited, either the people:


• suffering from hemochromatosis (excess iron in the blood)

• with kidney failure

• suffering from phenylketonuria

Dietitian advice

Even though diet only affects 15% of the body’s cholesterol, monitoring it can significantly lower blood cholesterol levels by reducing dietary cholesterol intake.

Thus, without eliminating them, we can reduce the consumption of foods containing a lot of saturated and unsaturated fatty acids, that is to say containing animal fats: meat, fish, eggs, cheese, etc.


In compensation, we can favor foods containing unsaturated fatty acids such as omega-3, that is to say containing vegetable fats: soybean, rapeseed, flaxseed oils, fatty fish, avocados, etc.

A good way to raise the “good cholesterol”, that is to say, the HDL level, an easy way is to practice regular physical activity: walking, running, aerobics, swimming, etc.
