Ultra Vitamin D3 – dissolved in olive oil for improved absorption

It is estimated that 50–80% of people have a vitamin D deficiency. This percentage is even higher in the winter months. People who spend less time outdoors, such as office workers, the elderly, and people with chronic illnesses, are particularly at risk. In addition, people with a dark or tanned skin tone are more likely to be deficient in vitamin D.

This is because the body produces vitamin D with the help of natural sunlight. If you have a dark or tanned skin tone, UV light has more difficulty penetrating the skin. The use of sunscreen also reduces the production of vitamin D.

Our vitamin D has been specially developed to supplement deficiencies with high-quality cholecalciferol (D3). This is the most absorbable form of vitamin D, which is much better absorbed than D2. We have also added olive oil to improve the absorption of vitamin D3.

  • Most absorbable form of vitamin D in its natural form
  • With olive oil for improved absorption
  • Good maintenance dose of 25 mcg D3 per capsule

Functions of vitamin D3

Vitamin D3 is an essential and indispensable vitamin for our health. It has countless primary and secondary functions in the human body. More and more is becoming known about vitamin D, as the number of people with a vitamin D deficiency is increasing rapidly.

  • It contributes to normal calcium levels in the blood
  • It helps absorb phosphorus and calcium from food
  • It is important for bone composition
  • It plays a role in bone formation
  • It is good for tissue growth and development
  • It plays a role in the process of cell renewal
  • It is good for our immune system
  • It is important for strong teeth
  • It is good for muscle function
  • It plays a role in mood and sleep

Vitamin D3 dosage

This product contains 25 mcg per capsule. This is a good maintenance dose for adults. For those at higher risk of deficiency (elderly people, people who spend little time outdoors), we recommend 75 mcg per day. You can take 3 capsules of this product.

BENEFITS

BENEFITS

Vitamin D3 is essential for our health. It is important for the immune system, hormone balance, bones and teeth. Vitamin D3 also plays a role in regulating the biological clock.

However, more than 70% of people have a vitamin D3 deficiency. This is a major problem, especially in the winter months, because the sun is less intense and we spend less time outdoors.

Vitamin D3 is dissolved in extra virgin olive oil, allowing this fat-soluble vitamin to be absorbed more efficiently by the body.

Vitamin D3 contributes to strong bones and supports a well-functioning immune system.

High-quality cholecalciferol (vitamin D3) helps to effectively replenish deficiencies, especially in cases of seasonal deficiencies or low sunlight exposure.

FORMULA

FORMULA

This vitamin D3 formula contains 25 mcg of cholecalciferol per dose. This is a good dosage for the whole year and also the most absorbable form of vitamin D3. One package will last you 200 days.

Our vitamin D3 is absorbed even better because we have dissolved it in extra virgin olive oil. Vitamin D is fat-soluble and is better absorbed when taken with fats.

Contains cholecalciferol (vitamin D3), the most biologically available form, which is better absorbed than vitamin D2.

The use of premium extra virgin olive oil as a solvent increases the stability and bioavailability of vitamin D3.

Each softgel contains 25 mcg (1,000 IU) of vitamin D3, a safe maintenance dose for long-term daily use.

Very good

Been using this "magnesium taurine" formula for quite some time, very satisfied with it, recommended.

Magnesium+taurine

I read that natuurlijk presteren.nl has the purest magnesium. And that's how I've experienced it too. It brings more energy during the day and makes sure I also have a well-cared-for mindset. It costs a bit but it also brings stability to daily life.

Ultra Vitamin D3

I've been taking it for about 2 weeks now and it really works! The capsules are easy to take and my body absorbs the vitamin well because it's dissolved in oil. I take two a day. Really nice, I'm starting to see myself again when I look in the mirror. Vitamin D is very important! Will definitely order again :)

I've been taking vitamin D3 for a few years and since I've recently started getting a few products here, I ordered this one as well. Good size, easy to take, they're small. And does what it should do.

This vitamin D is ideal if your vitamin D is up to standard.

Ultra Vitamin D3

Even though I'm an outdoors person, it turns out I don't get enough vitamin D from the sun. Vitamin D regulates calcium balance, which results in better bone formation and bone preservation. After a blood test my GP advised me to take vitamin D supplements. The Vit D3 has definitely done me good! It has certainly helped me!
