Is your Vitamin D level high enough?

There are still relatively many Dutch people who have too little knowledge of vitamin D. There should be more attention to vitamin D, because vitamin D is indispensable in our body. This is evident from a recent study by the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

What about your vitamin D level? Do the test here .

The research
Their analysis is based on 25 previous studies that have examined the relationship between vitamin D levels and survival rates for various cancer types. This study examined a total of 17,000 patients. The study found that patients with higher vitamin D levels had a greater chance of survival from breast, prostate, and colon cancer, thereby increasing survival rates. In addition, these researchers also say that vitamin D plays a crucial role in recovery for patients with leukemia, melenoma and Merkel cell carcinoma (skin cancer).

Why vitamin D?
Vitamin D is essential for the absorption of calcium and phosphorus in the body. These are two minerals needed to maintain healthy bones. Researchers also say that vitamin D binds to proteins (also called vitamin D receptors). These cells are active throughout your body. You can get vitamin D into the body in two natural ways. First, the body produces vitamin D when exposed to sunlight. This applies to about 85%. The other 15% comes from food, including fish, milk and eggs.

What else is Vitamin D important for?
Vitamin D levels have also been shown to be linked to:

  • Osteoporosis
  • Back pain
  • joint diseases
  • Dental problems
  • Infectious diseases (from flu to tuberculosis)
  • Cardiovascular diseases
  • High blood pressure
  • Autoimmune diseases
  • MS
  • Diabetes
  • Depression, mood
  • Pregnancy
  • Preeclampsia
  • ADHD in the child

How high should your vitamin D levels be?

  • At 80 the value is good
  • Optimum is between 100 and 120
  • At a blood value above 250 vitamin D becomes toxic, because it is a fat-soluble vitamin.

How can you increase your vitamin D levels?
The advice is to take 2000 IU (international units) daily.
You can get this from sunlight, food and supplements.
The strength of the sun should be above 3, to make your body able to produce vitamin d.
If you go for 20 minutes in the sun, you can get 10.000 to 20.000 IIE. The excess is broken down by your body. The problem is that the sun strength of more than 3 from October to May is almost nonexistent in the Netherlands.

Vitamin D is obtained with food from fish and margarine.
2 herrings per day provide 1600 IU. 100 grams of salmon 450 IU.
However, to get blood value 40 to 80, you need to take 1600 to 2600 IU per day!

A correct vitamin D level in the Netherlands is usually only obtained through food supplements in the period from October to May.

Top article. I have been suffering from vitamin D deficiency for years and until recently was taking supplements from kruidvat, but with the spread of the coronavirus more and more people seem to be buying vitamin D supplements and so they are often sold out. After some searching online I found a few providers of vitamin D supplements of which Flinndal seems to be the most reliable. Do you have any experience with this company? The supplements I would like to order are https://www.flinndal.nl/vitaminen/vitamine-d-forteGraaghad I heard your opinion.Greetings,Patrick
