These capsules have been specially developed for people who follow a vegetarian, vegan or flexitarian diet and with the aim of ensuring complete coverage of vitamins B12, iodine and selenium, all of which are important trace elements and often deficient in plant diets.

In addition, these capsules have been packaged in an eco-responsible, stearate-free and dye-free, infinitely reusable pillbox.

For Efficiency: 1000 µg of cyanocobalamin :

The vitamin B12 present in each capsule is provided in the form of a stable and most assimilable molecule: cyanocobalamin.

The high dose (1000 µg) per capsule represents 400 times the theoretical daily requirement. This dose limits intake to one or two capsules/week, with a maximum safety margin.

Essential Trace Elements :

Capsules also contain iodine and selenium.

Iodine, which is also present in each capsule, contributes to the proper functioning of the thyroid gland and its intake also helps to avoid deficiencies.

Selenium (an essential trace element) is involved in many metabolic functions and also acts to improve the absorption of iodine.

the benefits of vitamin B12:

Vitamin B12 supplementation is mandatory for vegan and vegetarian diets.

Vitamin B12 contributes to the balance of the body.

It acts on the functioning of the brain, the nervous system, it is essential for the proper development of the fetus and growing children.

The benefits of Trace Elements:

Iodine is essential for a good thyroid function and the risks of insufficiency are numerous in vegan and vegetarian diets.

Selenium is involved in many metabolic functions, (enzymatic reactions, immune system functioning, absorption of group B vitamins). The Selenium content of plants is difficult to predict and depends in particular on the soil in which they have grown.

Vitamin B12

Vitamin B12 is present only in foods of animal origin and in foods fortified with this vitamin.

For vegans, vegetarians and flexitarians with low consumption of animal products, vitamin B12 supplementation is compulsory for the former, highly recommended for the latter, and with doses higher than the official NRVs (Nutritional Reference Values) which are calculated for omnivorous diets.

Vitamin B12 is essential for DNA synthesis, for the production of healthy blood cells, for cell renewal (necessary for the good condition of the skin, among others) and for the proper functioning of our nervous system.

During pregnancy, vitamin B12 is essential for the proper nervous development of the fetus.

10 to 30% of Seniors have problems absorbing vitamin B12, regardless of their diet. In Canada, the official health agency recommends that they consume foods rich in vitamin B12 or take food supplements.

The issue of official RDAs/NRVRs* of vitamin B12

For vitamin B12 these references are estimated from omnivorous diets and are very underestimated for Vegans, at least in Europe (the American RDIs are 6 µg/day, i.e. 2.5 more than the NRVs!).

Moreover, there is no risk of vitamin B12 overdosage. The dozens of scientific studies on this subject all come to this conclusion.

*(Recommended Daily Intakes/ Nutritional Reference Values)

One capsule or two a week, is that reasonable?

“Yes, because the body can store sufficient reserves of vitamin B12 for a week, but only if the intake is significantly overestimated. »

One Argalys Essentiels capsule provides 1000 µg of cyanocobalamin per capsule, i.e. 400 times the daily dose (according to European NRVs), (and therefore 800 times for a dose of two capsules/week)!

This level is considered very safe by all nutritionist experts to cover the needs of vitamin B12 in all circumstances, and even to allow the reconstitution of the B12 stock for deficient individuals. 

Vitamin B12 deficiency and sub-deficiency: the risks ?

In children, including during the intrauterine period, vitamin B12 deficiency has an impact on brain and neuronal growth and development.

During pregnancy, it is essential for vegan, vegetarian and even flexitarian mothers-to-be to ensure full coverage of their B12 needs.

In adulthood, the effects of deficiencies are slower and more diffuse. One of the first perceptible symptoms is often an increase in tingling in the extremities of the limbs, but the lack of B12 has an impact on the proper renewal of red blood cells and tissues and is accompanied by negative symptoms of varying intensity (anaemia, diarrhoea, irritated tongue, visual and memory problems, etc.).

From the age of 60 onwards, vitamin B12 is less well assimilated, which further increases the risk of deficiency and reinforces the need for supplementation, including for omnivores.

Is this supplement vegan?
Yes, like all the supplements in our range, it is certified Vegan by The Vegetarian Society. It respects the dosage of Vitamin B12 recommended by the Vegan Federation.
How long does the pillbox last?
As an initial treatment: 2 months. Maintenance cure: 30 or 60 weeks depending on the type of diet. Our vitamin B12 + Iodine and Selenium formula is one of the most economical on the market.
Is the dosage sufficient to avoid deficiencies?
For Vitamin B12: yes. For Iodine and Selenium, it is impossible for legal reasons (Maximum Daily Dose) to increase the dosage of each capsule. It is therefore necessary to consider that this contribution is a 'plus' and to ensure dietary intake.
I am deficient in vitamin B12, should I take more than 2 capsules per week?
Yes, an attack cure is necessary in this case, with one capsule per day over a period of two months because the return to normal takes time. A regular blood test is recommended to verify the results of this treatment. It should be noted that outside the framework of the attack cure, it is preferable to space out the taking of the capsules by 3 or 4 days.
Can I give this supplement to my children?
Before the age of 8, due to the Iodine content, we recommend the Vegakid formula. After the age of 8, you can use this supplement without any problem.
