What is the target for my vitamin D level?
The purpose of taking vitamin D is to achieve a level that is
For hormones such as estrogen, progesterone and testosterone, the benefits of an optimal level are known for quite a while. Vitamin D is the oldest member in this mighty
of "steroid" hormones; it can be detected even in plankton.
The inhabitants of tropical countries achieve an optimal vitamin D level
with a natural life style. Our study was able to show that this is related to an improved survival rate (PMID:21572875).
As a target for the vitamin D level, more than 30 scientific institutions of the international organization GrassRootsHealth.net recommend a range of
40 to 60

What do I need to pay attention to when carrying out a vitamin D therapy?
Vitamin D: Before or after meals?
The daily dosage can be taken either before or after meals. In other words, your mouth should be empty.
Swallow or chew?
Absorption via the the oral mucosal membrane is more reliable than via the stomach. We therefore recommend to chew vitamin D instead of just swallowing it.
Spread the dosage over the day?
It isn't necessary to spread the dosage over the day. It can be taken all at once.
Must the vitamin D level be controlled with a blood test?
Correcting vitamin D to a natural level is a necessary process to maintain your health. Checking the vitamin D level after 1-2 months is appropriate, since after that time there has been a uniform distribution into all body tissues
Which laboratory values are helpful?
The inexpensive determination of creatinine, calcium and alcalic phosphatase (AP) documents the unhindered functioning of the kidneys, the calcium level and the bone activity.
Is it necessary to take calcium tablets?
No; it is best for the body to regulate the calcium intake itself, as soon as the vitamin D level is normalized. Then, the body can get the calcium from fruits, vegetables and water. Breast-fed infants can still get rickets; vitamin D helps here. In the case of bone problems, vitamin D - not calcium - is the irreplaceable assistant for self-help.
How exact must the dosage be followed?
It is permissible to distribute the dosage differently; however, the total dosage should be maintained. However, if the total dosage is distributed over a longer time period, it gets more difficult to recognize the relationship between intake and a health improvement.
Where do I find an inexpensive and safe supply source for vitamin D?
Our VitaminDService works independently from the different vitamin D suppliers. We do not participate in the sale. You can find a current discussion about the different products here:
Inexpensive vitamin D3.
What is the difference between vitamin D2 and D3?
Vitamin D3 is the biological form in the human body. Fungi produce vitamin D2. In Germany, no vitamin D2 is offered, since it doesn't provide any advantages. Within the normal levels, no difference could be shown. In the case of unphysiologically high levels of vitamin D (over 100 ng/ml), vitamin D2 is supposed to have disadvantages.
Why is there no phone information?
A phone consultation would be handy for everyone involved. Unfortunately, the medical professional code of conduct has good reasons to forbid an exclusive treatment by phone. A medical consultation by phone is only permissible after you become a patient by visiting a doctor's office for a vitamin D therapy.
Should I additionally take magnesium?
Yes, that can't hurt; magnesium deficiency is widespread, and hard to detect. As a complement, you can improve the magnesium level in your body. Since magnesium is not absorbed well orally, it is convenient to use a "transdermal therapy", for example a foot bath. You can find a useful product here:
Do I have to additionally take vitamin K2?
In most cases, obtaining and taking pharmaceutically produced vitamin K2 is not required. You can find a useful vitamin K2 product here:

Who is forbidden to take vitamin D3?
There is a rare disease (lifetime-risk: 1% of the population) called sarcoidosis. Symptoms for this chronic disease usually include an increase in temperature, fatigue and shortness of breath. If you have such symptoms, you should first consult with a physician and clarify the situation, for example by determining the serum value "ACE". Vitamin D is problematic in the case of sarcoidosis. If there is an increase in the calcium level, this can be corrected by an intake of cortisone.
Does vitamin D3 favor damage to the kidneys?
No; even in an extreme dosage of 500,000 units for pregnant women, vitamin D doesn't cause an increase of calcium in the blood. This is only observed regularly when the vitamin D level rises above 250 ng/ml. Kidney doctors (nephrologists) who work with maintaining the function of the kidneys and with blood cleaning regularly give their patients
®, since it keeps the bones and the kidneys functional.
Does vitamin D3 help cause kidney stones?
No, vitamin D doesn't increase this risk. The risk of kidney stones is increased by other factors: drinking low amounts of liquids, chronic infections, intake of calcium tablets, intake of
vitamin D (calcitriol). On the other hand, the vitamin D of which we are talking on our website is also known as
vitamin D (vitamin D3).
Does vitamin D3 provide protection for the kidneys?
Yes. With a normal vitamin D level, Vitamin D3 will typically provide an improvement compared to a vitamin D deficiency. It turns out that a lack of vitamin D increases a tendency for chronic infections and thus kidney stones.
Does it matter that I smoke?
The intake of vitamin D is doubly valuable for smokers. On the one hand, the cancer risk is greater for smokers; on the other hand, the vitamin D level is reduced when you smoke. For therapy, people who smoke a lot commonly require a vitamin D dosage that is one-third higher, to achieve the desired objectives. This makes it convenient to have controls, and to increase the intake.
Why can't I input a weight lower than 9 kg?
For infants in their first year, vitamin D prophylaxis has been used successfully for years. The enclosed instructions of vitamin D products defines the 50 year old rule: 1000 units for prematurely born babies, otherwise 500 units. Since prematurely born babies which are underweight can benefit from 1000 units, this dosage should not cause problems for normal-weight infants. Besides, the increased intake of 1000 units a day for infants can compensate occasional gaps in the intake.
Is it correct that vitamin D is dangerous, since it accumulates in the body as a fat-soluble substance?
If vitamin D were not fat-soluble, a human would not be able to accumulate reserves, and would not be able to survive winter. However, the accumulation in body tissues is compensated by a continuous reduction. The steps calculated above keep this vitamin D balance within the healthy range. Thus, you have to compensate the continuous reduction of the vitamin D level with a correct permanent dosage.
How can all this information be summarized?
The conclusion of all the questions and answers is: It is not a mistake to correct a vitamin D deficiency,. A lack of iron is corrected with an iron therapy. A lack of vitamin B12 is corrected with vitamin B12. Similarly, a lack of vitamin D is a clear indication that a treatment is appropriate. A lack is harmful; correcting it has a great health benefit.
Why do you sometimes hear that vitamin D is not at all necessary?
For many decades, physicians were taught the creed that in principle we don't have a lack of vitamins. This is now contradicted on a daily basis by thousands of laboratory values. Of course this will cause a controversy between the old belief and the new findings.
