From October to March, the sun in the Netherlands is too low for your skin to produce enough vitamin D. If you also work indoors a lot, it becomes even more challenging. This Vitamin D3 (cholecalciferol) from LUTO Supplements provides 3000 IU per softgel, dissolved in virgin olive oil. One jar contains 100 units, enough for over three months.
Vitamin D3, or cholecalciferol, is the same form that your skin produces when exposed to sunlight. It is a fat-soluble substance. This may sound technical, but in practice it simply means this: your body absorbs vitamin D3 better when it's accompanied by fat. This is where the olive oil in this softgel comes in. The vitamin D3 (cholecalciferol) is already dissolved in virgin olive oil, so your body doesn't need to break down a dry powder first. The oil does the preparatory work. Compare it to the difference between a dry cracker and a well-buttered slice of bread. The same nutrient, but your body can utilize it differently. The softgels themselves are small and tasteless, making daily intake simple.
As soon as you take a softgel, your liver converts cholecalciferol into an intermediate form. Then, your kidneys create the active form. This active form binds to receptors found in many tissues. And that's where it gets interesting, because vitamin D does more than most people think. It contributes to the normal absorption and utilization of calcium and phosphorus. It contributes to the maintenance of normal bones and normal teeth. But it doesn't stop at your skeleton. Vitamin D contributes to normal muscle function and the normal functioning of the immune system. Furthermore, it plays a role in the process of cell division. What many people don't know: vitamin D also contributes to normal blood calcium levels. This goes beyond just strong bones.
The dosage of 3000 IU (75 mcg) per softgel is significantly higher than what is found in basic products. These typically range from 400 to 800 IU. For people who get little sun exposure, have darker skin, or desire targeted supplementation during the autumn and winter months, such a higher dosage is common. At 1500% of the reference intake, this may seem like a lot, but remember that the reference intake is based on a minimal requirement. This vitamin D supplement is intended for targeted supplementation, not for cautious, incidental intake. One softgel daily with a meal is sufficient.
Besides vitamin D3 (cholecalciferol), this softgel contains virgin olive oil, gelatin, glycerin, and purified water. No long list of excipients, no added colors, no unnecessary fillers. This simplicity is a deliberate choice. The olive oil serves as a carrier and aids the absorption of the fat-soluble vitamin. The gelatin forms the shell. You don't need more for a product that aims to do one thing: supplement your daily vitamin D3 intake.
With 100 softgels in the jar, you have a supply for over three months. A clear product with a clear formula. Cholecalciferol in olive oil, at a dosage that matters. Especially convenient when the sun is once again scarce for months.
Vitamin D3 is fat-soluble. In this softgel, the cholecalciferol is already dissolved in virgin olive oil, making it easier for your body to absorb it through micelle formation in the intestine than from a dry tablet.
The 75 mcg (3000 IU) dosage is well above basic 400 to 800 IU products, but remains below the current upper limit of 4000 IU per day. A targeted dosage for adults who want serious supplementation.
At one softgel per day, this jar will last you for over three months. This is convenient if you start in October and want to continue until spring without having to reorder in between.
Besides vitamin D3, this softgel contains only olive oil, gelatin, glycerin, and purified water. No colorants, no fillers, no long list of additives. The olive oil serves as both a carrier and an absorption enhancer.

Vitamin D is the generic name for a group of fat-soluble vitamins. Vitamin D3, or cholecalciferol, is the specific form your skin produces itself when exposed to sunlight. There is also vitamin D2 (ergocalciferol), which comes from plant sources. Studies show that D3 generally increases blood vitamin D levels more effectively than D2, making it the most commonly used form in supplements.
With a meal containing fats. Vitamin D3 is fat-soluble, so your body absorbs it better in the presence of fats. In this softgel, D3 is already dissolved in olive oil, which already promotes absorption. But a meal completes the process. The time of day doesn't matter: morning, noon, or night, as long as you take it with a meal.
From October to March, the sun in the Netherlands is too low to cast enough UVB radiation onto your skin. Without this radiation, your body doesn't produce vitamin D3. If you also work indoors a lot during the day, it becomes even more difficult to get enough vitamin D from sunlight alone.
No, not for most adults. The common supplementation range in studies is between 1000 and 4000 IU per day. At 3000 IU, you are well within this range. The reference intake of 5 mcg (200 IU) is based on a minimal need, and not on what you need in case of limited sun exposure. Do you have doubts or a specific condition? Then talk to your doctor.
After ingestion, your liver converts cholecalciferol into 25-hydroxyvitamin D. This is an intermediate form that circulates in your blood and is also measured during a blood test. Then, your kidneys produce calcitriol, the active form. Calcitriol binds to vitamin D receptors present in many tissues and thus regulates, among other things, calcium absorption in your intestines, bone formation, and immune cell function.
In a tablet, vitamin D3 is generally compressed as a dry powder with fillers. A softgel contains D3 dissolved in oil, in this case virgin olive oil. Since vitamin D3 is fat-soluble, this oily solution offers a practical advantage: your body does not need to break down a dry mass first. The oil, along with the fats from your meal, forms micelles in your intestines, which facilitates the absorption of vitamin D3.
