Why do we need to take a vitamin D3 rich food supplement?
Our diet provides us with a small amount of vitamin D. The moderate exposure of our body to the sun allows our body to synthesise a large part of the necessary vitamin D.
When our body is not sufficiently exposed (especially in winter), our body synthesises less vitamin D3, and we are therefore more likely to be deficient
Why choose a plant-based vitamin D supplement like Optim D3?
Optim D3 is a natural and vegetable solution to increase its vitamin D3 level. Its concentration is ideal for the whole family: children from one year old and adults.
The coconut oil extract used in the composition gives it a pleasant taste and excellent stability.
Who can take Optim D3?
Children from 1 to 10 years old: 1 drop per day
Children over 11 years old and adults: 2 drops per day
Pregnant and lactating women: consult your doctor or pharmacist to know your needs and adapt the intake accordingly.
What is the maximum amount of vitamin D3 I can take daily?
One drop of OPTIM D3 provides 500 IU/day.
The maximum tolerable level in Europe (EFSA) is 4000 IU/day,
Ask your doctor for a vitamin D analysis
It is always advisable to determine your level of vitamin D (25(OH)vitamin D – Calciferol) and ask a health professional to determine the optimal intake, as several criteria come into play (age, weight, blood levels, illness, medication, etc.).
Once I have started treatment, how long do I have to wait to have a blood test to see how my markers are?
After 3-4 months, to ensure you have a significant increase in 25(OH)vitamin D.
Is it better to take vitamin D in drops or tablets?
We have chosen a dropper bottle with coconut oil because it is easy to take or give. This allows the dose of vitamin D to be adjusted for adults and children. In addition, a recent paper shows that absorption of vitamin D3 from an oil solution (in oil) does not alter its effect if taken with or without meals. (Cavalier et al. 2016)

What is lichen?
Lichen is an organism resulting from a symbiosis between a fungus (representing 90% of the total) and an alga. Lichen is resistant to extreme conditions: lack of water, high-temperature variations (hot/cold), very low temperatures, intense ultraviolet rays and ionising radiation.
Why choose lichen?
Until now, most of the vitamin D3 supplements available on the market were either synthetic or derived from lanolin (sheep wool).
The lichen that we have selected grows in the wild in Canada. The species is not threatened, and harvesting takes place seasonally.
Vitamin D3 from lichen is perfectly adapted for vegetarians, vegans and vegans, as well as for anyone who prefers a natural, sustainable and quality plant origin (without pesticides, GMO-free)
Are there any contraindications or drug interactions with plant-based vitamin D?
In principle, vitamin D has no contraindications. However, if you suffer from hypercalcaemia, allergy to the ingredients in the formula, hypercalciuria or hyperparathyroidism, you should consult a doctor before taking vitamin D.
With regard to drug interactions, certain groups of drugs, such as anticonvulsants, glucocorticoids, antineoplastics, may increase the metabolism (excretion) of vitamin D and thus decrease 25 (OH) vitamin D (Calciferol) levels.
Vitamin D has evolved from a single vitamin to a large prohormone with multiple effects.
Its action is linked to bone mineral metabolism, phosphocalcic balance, and essential effects on multiple cells and mechanisms (cell cycle, endocrine system, immune system, intestinal microbiota…)
Therefore, Vitamin D deficiency is linked to rickets and an increased risk of diabetes, cardiovascular disease, oncology, infection, and autoimmune diseases. (Zaluaga, 2011)
In France, 80% of the population has a vitamin D deficiency (levels below 75 nmol/l, optimal minimum level) (Vernay 2006-07)I
In Belgium, 95% of patients do not reach the recommended value (75 nmol/l). (DAoudi 2009)
Serum calciferol concentrations (25(OH) vitamine D)
1 ng/ml = 2,5 nmol/L
The body absorbs only 10 to 20% of vitamin D through the diet. The “sun” vitamin or vitamin D3 (cholecalciferol) – the most active form – is synthesised in the skin by converting 7-dehydrocholesterol after exposure to UVB (ultraviolet-B) sunlight,
Lack of sun exposure and skin ageing, for example, reduce the synthesis of vitamin D or its active metabolites, so in many cases, without vitamin D supplementation, it is impossible to maintain optimal vitamin D levels, especially during the winter period.
