Vitamin D3 2000 IU is a highly absorbable dietary supplement for immunity, bones and muscles. One softgel capsule contains 2000 IU of vitamin D3. The source is the most bioavailable animal form of cholecalciferol in a small amount of vegetable oil, which significantly increases its absorption. Its purity is regularly tested by independent laboratories for microbiology, heavy metals and the amount of active ingredients.
Vitamin D3 2000 IU by GymBeam contains 50 µg of pure vitamin D3 per capsule. This represents 1000 % of the daily reference intake value for vitamin D. The source of vitamin D is cholecalciferol, which is among the most absorbable forms for supporting immunity, bones and muscles. Product quality is guaranteed by independent laboratory tests, the results of which can be found in the laboratory tests section.
The body can naturally produce vitamin D on its own, so at first glance it may seem that you do not need a dietary supplement with vitamin D at all. UV radiation from the sun naturally activates the vitamin D precursor (7-dehydrocholesterol) found in the skin. This starts the entire process of the body's own vitamin D production, which is then completed in the liver and kidneys, creating the active form of vitamin D, calcitriol, which is able to act in the body.¹
However, there is one important catch. For much of the year in Europe, except summer, sunlight may not be sufficient for vitamin D synthesis. Up to 40 % of the European population has insufficient vitamin D blood levels.² This is not a marketing claim, but a fact confirmed by many scientific studies.
Vitamin D is also found in food, so the body's own production through UV radiation from the sun is not its only possible source.³
So if you do not have fatty sea fish on your plate several times a week, do not eat several eggs daily, or do not deliberately choose foods fortified (enriched) with vitamin D, you may have a real problem meeting your vitamin D intake.
For those who are unable to achieve sufficient vitamin D synthesis through sun exposure or a regular diet, taking a dietary supplement containing vitamin D is an option. Vitamin D3 2000 IU by GymBeam solves this problem simply – one capsule a day provides the body with vitamin D in a highly bioavailable form, at a daily dose of 1000 % of the reference intake value for an adult.
1. An effective form of vitamin D3
Vitamin D is found in regular foods and dietary supplements in two forms: the animal-derived form, cholecalciferol, and the plant-derived form, ergocalciferol. Studies conclude that cholecalciferol is converted into the active form of vitamin D in our body more effectively than ergocalciferol.⁴ This is precisely why we chose this form for our product.
2. A sufficiently potent yet safe dose of vitamin D3
One daily serving of Vitamin D3 by GymBeam contains 50 µg (2 000 IU) of vitamin D3, which is 1 000 % of the reference intake value (RI; NRV – nutrient reference values in English). The number may seem high at first glance, but the RI is an EU legislative value set at 5 µg (200 IU). However, expert recommendations are significantly higher today.
Why do we go higher than 600–800 IU? Official recommendations target blood 25(OH)D levels of around 50 nmol/l, which is the minimum for maintaining normal bone health. Part of the expert debate now leans towards values above 75 nmol/l.9 A dose of 50 µg will help you reach this level more easily.
And isn't 1 000 % RI too much? No. According to EFSA, the safe long-term daily intake for an adult is up to 100 µg (4 000 IU)8. Our dose is half of that.
Tip: There is no ideal dose for everyone. If you want to set it precisely, have your blood vitamin D 25(OH)D level measured in a laboratory. A dose of 50 µg (2 000 IU) is designed to suit most people with regular use.
3. Ideal absorption thanks to an oil base
Vitamin D is one of the so-called lipophilic vitamins, meaning it is fat-soluble and pairing its intake with fat intake is more than suitable for optimal absorption.10 That is why we placed vitamin D in a softgel capsule containing a small amount of safflower oil, which supports its absorption.
Although vitamin D is currently being studied in relation to a wide range of health areas with positive results, we do not want to make miraculous claims about vitamin D that are not reliably supported by science. Therefore, we only state officially approved health claims.11
1. Immune system
Vitamin D supports the proper functioning of the immune system. This makes it one of the most watched micronutrients, especially during the colder months of the year, when the body is exposed to a greater bacterial or viral load.
2. Calcium and phosphorus absorption and utilisation
Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus. These are essential components of the structure of bones and teeth. Without sufficient vitamin D, the body cannot effectively absorb or utilise calcium and phosphorus obtained from food, no matter how high their intake is.
3. Healthy bones and teeth
Vitamin D contributes to good bone and dental health. This is appreciated by growing children, people recovering from illness, athletes and older people alike.
4. Cell division
Vitamin D also plays a role in the process of cell division, which is essential for maintaining the functioning of cells, tissues and organs. This process takes place throughout life and is vital for maintaining health.
6. Muscle function
Vitamin D contributes to maintaining normal muscle function. This is important for all athletes as well as active seniors.
Who is Vitamin D3 2000 IU suitable for?
1. Athletes and active people
Because vitamin D contributes to proper muscle function and calcium metabolism, two areas that are key for performance and recovery.
2. Older people (60+)
As we age, the skin's ability to produce vitamin D from sunlight decreases, while the importance of healthy, strong bones increases. Focusing on sufficient vitamin D3 levels and adequate intake is one of the most common nutritional recommendations for this group.
3. People with limited sun exposure
Office work, city living, shift work. Just because it is summer and the sun shines all day does not automatically mean your vitamin D levels are sufficient in summer if you actually spend most of the day indoors. If you want to stay fully informed about your health, we recommend having your vitamin D level measured and, in case of deficiency, starting suitable supplementation even during the summer months.
4. Women, especially after menopause
The relationship between sufficient vitamin D intake and healthy bones is undeniable. This relationship becomes even more important after menopause, when women may experience faster loss of bone density.
5. People on a calorie-reduction diet or taking GLP-1 products
A calorie-reduction diet carries the risk of reduced intake of a range of vitamins and minerals. This is why, when on a calorie-reduction diet, you should pay even more attention to the intake of these nutrients, including vitamin D.

Dosage
Take 1 capsule daily. Never take it on an empty stomach; take it with a meal containing fat, which will further support vitamin D absorption. There are several ways to incorporate Vitamin D3 2000 IU into your daily routine.
- In the morning with breakfast. It fits naturally into your routine, and you can tick it off first thing in the morning.
- With your main meal of the day. If your breakfasts are mostly carbohydrate-based and contain virtually no fat, it may make sense to take your vitamin D with a lunch richer in fats instead, to support optimal absorption.
- At the end of the day with dinner. We have come across claims several times that vitamin D should not be taken in the evening because it supposedly signals to our body that it is daytime and the sun is shining, which may worsen sleep. There is a theoretical hypothesis that vitamin D could slightly affect melatonin production (vitamin D receptors are also found in the brain centre that regulates circadian rhythms). However, clinical evidence of a real impact on sleep is lacking, and according to the available literature, you can take vitamin D at any time of day without concern.
- All year round, especially from autumn to spring. During periods of low sunlight, vitamin D supplementation makes the most sense. However, supplementation should always be based on your current blood vitamin D level.
- Do not exceed the recommended daily dose, but... This magical sentence is required by current legislation. However, we have emphasised several times in the description that there is simply no single optimal vitamin D dose for everyone. Therefore, take the dose of 1 capsule daily (50 µg, 2000 IU) from us as a basic safe recommendation that will most likely suit you. If you want to tailor your vitamin D supplementation precisely according to your blood levels, we recommend consulting a doctor or nutritionist about the dosage.
