Vitamin D is an essential substance for the body.
It behaves like a hormone and multiplies the physiological effects. However, 60-70% of the European population is said to be deficient.

Extracted from Lichen Boreal, our vegetable vitamin D3 is integrated with extra virgin rapeseed oil and combined with vitamin E for optimal absorption.
With a dosage of 500 IU per spray, it is ideal for daily family use.

Vitamin D is essential for the proper functioning of the body: it plays a particularly important role in strengthening the immune system and contributes to the maintenance of normal bones and teeth, particularly by helping to fix calcium. 

Plant-based vitamin D : 

We have chosen a vitamin D3 (cholecalciferol) extracted from Lichen Boreal: a 100% vegetable vitamin. 

There are variants of vitamin D, but the best known are vitamin D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D2 is mainly found in plants and vitamin D3 is mainly of animal origin, except for the one we propose which comes from lichen.

 The lichen we have selected grows wild in Canada, Scandinavia and Ireland. 

Highly assimilable, good bioavailability: 

Our vitamin D3 is in the form of a sublingual spray. This form facilitates the use and distribution (especially to children) and the good bioavailability of vitamin D. 

The association of vitamin D3, which is a fat-soluble vitamin, with rapeseed oil also contributes to its optimal absorption. 

For the whole family and in all circumstances:

Vitamin D3 is essential to the body, for children and adults alike. 

The Spray makes it easy to administer and its dosage (500 IU/Spray) allows the bottle to be adapted to the whole family, without any risk of overdosing. 

And thanks to its small size, you can take it everywhere with you, it is even accepted in the cabin luggage of the planes (volume lower than 100 ml). 

Product advantages :

  • For the whole family
  • 240 sprays per bottle
  • Eco-friendly
  • Plant origin: Certified Vegan

Why supplement with vitamin D?

Vitamin D is essential for the proper functioning of the body.

Although nicknamed the sunshine vitamin, because it is synthesized by the skin under the action of the sun’s UVB rays, it is estimated in practice that 70 to 80% of men and women in the European population have a vitamin D deficiency.

According to the Anses, infants, the elderly and pregnant women are considered the most at risk. But whatever the age, a contribution in vitamin D is essential.

The benefits of vitamin D are numerous.

Vitamin D:

  • Contributes to the normal functioning of the immune system in adults and

  • Plays a role in the process of cell

Vitamin D: a pro-hormone 

A vitamin has the following definition: an “active, vital organic substance, essential in minute quantities for the growth and proper functioning of the body, which cannot synthesize it itself” (Jeuge-Maynart, 2011).

In practice, vitamin D occurs naturally in two main molecular forms:

  • Vitamin D2 (ergocalciferol)
  • Vitamin D3 (cholecalciferol)

Vitamin D2 is synthesized by exogenous sources: certain plants and fungi. As for vitamin D3,

it is mainly of animal origin. In the past, it was obtained exclusively from liver extracts or lanolin from sheep’s wool, but it is now possible to produce it from certain lichens. It is also this form that is synthesized by the body under the action of the sun.

This form is therefore of exogenous and endogenous origin.

Therefore, vitamin D is considered more of a pro-hormone because its source is not exclusively exogenous.

The mechanism of vitamin D absorption

When vitamin D is synthesized by the skin :

In the epidermis and under the action of heat, pre-vitamin D3 is converted into vitamin D3. This form diffuses through the skin and is released into the bloodstream.

Vitamin D from the diet :

Dietary vitamin D, both ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3), is slowly absorbed in the proximal part of the small intestine before entering the lymphatic circulation and then the systemic circulation and liver (Holick, 2007).

After its synthesis or absorption by the intestine, vitamin D, whether from endogenous or exogenous sources, enters the bloodstream where it is bound to several transport proteins.

It will then undergo two hydroxylations which will make it possible to obtain the hormonally active form of vitamin D: calcitriol.

  • Hepatic hydroxylation :

 

Once the vitamin D has reached the bloodstream, it reaches the liver. It is there that it will undergo its first transformation. The enzymes responsible for this reaction are hydroxylases. Calciferol undergoes hydroxylation and calcidiol or 25-hydroxycholecalciferol [25(OH)D] is obtained.

The hydroxylated form obtained returns to the general circulation. In this new form, calcidiol has a half-life of about 3 weeks in plasma. It therefore represents the body’s vitamin D reserves and is the reason why this form is used as a serum marker for vitamin D levels in blood tests.

  • Renal Hydroxylation:

The calcidiol will then reach the kidneys where it will be transformed into 1,25 dihydroxycholecalciferol (1,25(OH)2D). It is in this form that vitamin D becomes an active hormone, referred to as a steroid hormone. In this form, it plays its best-known role in bone metabolism: a hypercalcemic and hyperphosphatemic activity. This means that it stimulates the absorption of calcium and phosphorus in the intestine, contributing to the bone mineralization mechanism (synthesis of bone compounds, particularly collagen).

The main actions of vitamin D

The historically established role of vitamin D is in bone mineralization and maintenance of phosphocalcium balance.

It therefore plays an essential role in the growth and maintenance of bones and joints, but also in all functions where calcium is directly involved:

  • In muscle tone;
  • In blood coagulation
  • In the transmission of nerve impulses

 

Vitamin D also acts on other physiological mechanisms such as the stimulation of the immune system and the cell division process. Thus, a vitamin D deficiency will cause a decrease in the absorption of calcium and phosphate, which will lead to a loss of bone mass that can cause rickets in children or osteomalacia in adults (bone fragility). But considering that the active form of vitamin D is involved in many processes in the body, deficiency can also cause other symptoms such as fatigue, dizziness, muscle pain or immune dysfunction.

Actual vitamin D requirements and intakes

The nutritional reference for the population defined by the National Agency for Food Safety (ANSES) for Vitamin D is 15 micrograms/day for adults (i.e. 500 International Units IU).

In reality, nutritional intakes are frequently insufficient and numerous studies tend to prove this. In fact, the reference intakes do not take into account the variability that exists according to an individual’s lifestyle and state of health. Thus, the INCA study conducted in France shows that the current recommended average intake is insufficient (between 3 and 6 micrograms depending on the demographic category).

Nevertheless, expert opinion agrees that there is currently a lack of solid data to establish more precise recommendations for vitamin D requirements. Clinical trials are still underway and results should be available in the next few years.

Why supplement with vitamin D? 

Although vitamin D is stored in the body to cover needs when intakes decline, many populations are deficient in vitamin D.

The populations most at risk are :

  • Young people (from birth to the end of growth)
  • Pregnant women
  • Senior citizens
  • People with a predominantly or totally plant-based diet
  • All people with low sun exposure

The reasons for impairment are many and varied:

  • The body’s vitamin D reserve is low and can only meet daily requirements for a
  • Diet: Few foods contain significant amounts of vitamin D
  • Sunshine: this varies according to the season and geographical location. In winter, the epidermis rarely produces vitamin
  • Age: With age, skin synthesis of vitamin D decreases because the capacity of the epidermis to synthesize vitamin D is altered
  • Skin pigmentation: dark-skinned individuals need more sun exposure than light-skinned individuals to produce equal amounts of cholecalciferol (Meunier, 2008).
  • Decreased bioavailability: Crohn’s disease, Obesity

These are the reasons why vitamin D deficiency is common in the general population and why taking a vitamin D supplement can be a useful precaution.
