Vitamin D3 5000 IU is an exceptional supplement containing 5000IU of vitamin D3 (the most bioavailable form) per softgel. It is enriched with sunflower oil to maximise its absorption.
Daily or twice a week supplementation with Vitamin D3 5000 IU produces a rapid increase in circulating levels of the vitamin, as confirmed by blood tests, and has a positive effect on cardiovascular, endocrine, nervous system, immune and cognitive function.
Who is Vitamin D3 5000 IU aimed at?
The latest studies show that between the months of October and April, almost everyone (1-4) living at a high latitude has an inadequate level of vitamin D (5-6). March sees levels reach their lowest point (7-8).
Vitamin D3 5000 IU is thus aimed at anyone living in France, Italy, Germany, Spain, the Netherlands, Portugal, Poland, the UK, Canada and the United States throughout autumn and winter.
Vitamin D is produced by the body on exposure of the skin to the sun’s ultra-violet rays (UVB). However, in temperate regions of the Northern Hemisphere, the conditions are not conducive to this process, both because of the sun’s angle of elevation and the weather during these seasons, as well as urban lifestyles: at this time of year, we tend to stay indoors and cover ourselves up too much to maintain adequate vitamin D production. Peak production rapidly plummets from November onwards and reserves are quickly exhausted.
Vitamin D3 5000 IU can also be used in the spring and summer by many groups of people (40% of individuals have inadequate levels even during these periods):
- Those with dark skin who live at high or middle latitudes, because they need more sun than a fair-skinned person to produce the same amount of vitamin D.
- Those who are less mobile or who do not get much exposure to the sun.
- Those who are overweight, because vitamin D produced from the sun’s rays is sequestered by the fatty layers under the skin.
- Those over 50 (9), both due to less exposure to the sun (delicate skin) and less efficient conversion of vitamin D precursors into vitamin D in the superficial epithelial layers of the skin.
- Those suffering from bone disease.
- Those with malabsorption problems and inflammatory bowel disease because this makes absorbing fats more difficult.
- Those following specific diets (excluding meat, fish, eggs or products fortified with vitamin D).
- Those living in areas of high pollution, as CO2 absorbs UV rays.
- Those who regularly use UVB-blocking sunscreens (with an SPF above 15) as these can prevent up to 99% of UVB from penetrating the skin.
For all these groups of people, Vitamin D3 5000IU is often the safest way of quickly increasing their levels of vitamin D and of maintaining them throughout the year, now available to buy at Supersmart.
What are the effects of too little vitamin D?
Vitamin D is not really a vitamin: it should actually be thought of as a hormone. It performs many functions in the body, the best-known of which are its key roles in the intestinal absorption and binding to bones of dietary calcium, in muscle function, in maintaining cognitive function, in supporting the immune system and in tissue cell renewal.
The effects of a lack of vitamin D may go unnoticed for years but in the long term, they can be serious: softening of bones (osteomalacia), osteoporosis, bone pain, muscle weakness, joint pain (particularly in the wrists, ankles and shoulders), migraines, increased risk of depression, insomnia, hair loss (10) …
Conversely, optimal vitamin D levels bring numerous benefits for our health:
- Optimisation of bone health (11-13).
- Reduced risk of cardiovascular disease and stroke (at doses of at least 600IU a day (14)).
- A decrease in blood pressure (at doses of at least 2000IU a day (15)).
- Improved blood cholesterol levels (at doses of at least 2000IU a day (16)).
- Increased strength and muscular balance (at doses of at least 800- 1000 IU a day (17)).
- Reduced risk of neurocognitive problems and auto-immune diseases.
- Potential reduction in fibromyalgia pain (at doses of at least 2400 IU a day) (18).

adults. Take one softgel a day or as advised by your therapist.
Warning : At doses above 2000 IU a day, a 25-hydroxyl vitamin D analysis should be carried out. If you suffer from kidney disease, do not take vitamin D3 without consulting your therapist. Do not exceed 10,000 IU a day, all sources combined, without the advice of your therapist.
