Kelp: a supplement for your metabolism

Many consider kelp to be a supernutrient, while others question the extent it’s needed in the pantry. Is it simply a fashionable algae or are the antioxidant and anticancer properties attributed to it true?

We could say that kelp is a gift from the sea, an alga belonging to the Fucaceae family that contains numerous vitamins, particularly those of group B, essential for the body’s regeneration. Join us to learn more!

What is Kelp

What is Kelp algea?

Kelp algae, which in Europe is known as ‘Algivit’ , grows in the shallow areas of the Patagonian coastline and is brown in colour, with a flat and elongated structure.It’s a natural source of iodine.

It’s consumed in abundance in Asian countries such as China and Japan, where there’s a great tradition of incorporating seaweed into their diet, for health and vitality.

It grows near the surface of the sea, where it absorbs the sunlight it needs to carry out photosynthesis, which gives it its characteristic greenish colour. Due to its shape, it’s also known as laminaria.

What does Kelp do?

If we had to define what kelp algae taste like, we could say that it taste of the sea, which is due to its high content of vitamins and minerals such as iodine, (which regulates the thyroid gland) and calcium, (which helps to achieve strong bones), as well as trace elements and other nutrients such as fibre, perfect for dealing with constipation and keeping the body free of toxins and harmful substances.

What are its properties?

The varied composition of kelp includes 30 minerals and is rich in iodine, calcium, silicon and sulphur. In any case, let’s look at its individual parts…

Composition kelp

Low glycemic index carbohydrates

Although it provides a greater number of carbohydrates than protein (specifically 8.3 grams of carbohydrates and 1.6 g of protein per 100 grams), it has a low glycemic index, meaning it avoids low blood sugar spikes.

In addition, the protein contained in the algae is plant-based and of high biological value, which means that it’s rich in essential amino acids.


We’ve already noted that they’re a source of potassium, iron and magnesium, but also of iodine and calcium, to which we need to add sodium, phosphorus, copper, zinc, manganese, boron and chlorine.

Iodine is a key mineral for controlling the thyroid gland, which we’ll discuss below, but it’s also essential for the proper functioning of the nervous system and the brain, moisturising the skin and preventing wrinkles. And its high concentration of calcium helps to strengthen bones, meaning taking kelp is a good idea during the menopause.


Packed full of vitamins. That’s kelp. Among the extensive catalogue of vitamins it contains are vitamin A, C, D, E, K and the B complex. This is why it protects the organs and skin from free radical attack, combating cellular oxidation, the formation of spots and the development of cellular DNA alterations. Some sources even suggest Japanese women may suffer less from ovarian, endometrial and breast cancer as a result of taking this sea vegetable.


Its high concentration in alginate helps to regulate intestinal transit, offering a solution to constipation problems when it’s included in the diet. You may have noticed that when you go on a weight loss diet you eat less fat and find it harder to go to the toilet. When this happens to you, algivit algae can help you.


Its high water content is similar to that of pineapple or artichoke, meaning this algae is considered a natural diuretic, helping the kidneys to function optimally, purifying the body of toxic substances, and cleaning and purifying the arteries.

These elements are essential for health, forming part of the bones, muscles, teeth, blood, nerve cells and white tissues, and also acting as catalysts for various reactions in the body, being decisive for the production of hormones.

The high concentration of micronutrients in Kelp makes it a highly recommended substance for those with some kind of deficiency, which is why more and more people are considering adding it .

You know when someone tries to lose weight, really goes at it, following a rigorous diet and exercising regularly, and they still don’t succeed? The key could be that they suffer from hypothyroidism, or an underactive thyroid gland.

In terms of symptoms, it varies, including fatigue, forgetfulness and even lack of concentration, lack of libido, impotence, irritability and worsening health of hair, nails and/or teeth all likely to appear.

Not surprisingly, approximately 80% of all the iodine in the body is located in the thyroid and its deficiency often has serious consequences for your health.

Fortunately, one of the greatest benefits of algivit consumption is that it helps treat thyroid function. In particular, it fights hypothyroidism and optimises metabolism.

Ideally, the mineral iodine should be taken from a contaminant-free and pure source like Kelp, which normalises the situation and reactivates the thyroid. Consuming this mineral is a great alternative to salt intake, especially for those who suffer from high blood pressure and have to reduce their sodium consumption.
