Very recently one my fan asked me why I never suggest people to use vitamin D3 for boosting immunity and healing various diseases, because many healers today are forcing D3 supplements as ultimate cure for many diseases: from the flu, various autoimmune diseases to the cancer. There is only one problem: overuse of D3 (or D2) can be as dangerous, as lack of it. Due to the overpromotion of D vitamin supplements, so many people today are literally poisoning themselves by taking massive amounts of this substance.

What is good to know about vitamin D before rushing to buy tones of vitamin D supplements?


1. Vitamin D is not vitamin at all. It is a hormone (secosteroid). As a hormone, it is very active substance (far more active then any vitamin) and scientists like to compare it`s strength with corticosteroids (hormones of adrenal glands, that are extremely dangerous to be taken (please read my Hub about CORTICOSTEROIDS )).

2. Vitamin D supplements come in two forms:

  • as D3 (derived from animals)
  • as D2 (derived from fungus or yeast)


3. "Vitamin" D3 (calcitriol) is derived from animals (lamb`s wool that has been exposed to the UV rays), as such is very bioactive, and has quick effect on human body, but not always the good one. Vitamin D is hormone, and hormones are always tricky to use, even the smallest quantity of bioactive animal or synthetic hormones can produce massive imbalance in the body - real need for any hormone differs from day to day, from moment to moment. Only natural way of taking hormones are homeopathic ones or phyto-hormones, (in case of hormone/vitamin D we primary need sunshine) - everything else, if not taken very carefully, can cause more troubles then people are aware of.

Vitamin D3, when overdosed through the supplements, is suppressing immune system, instead of improving it. Despite the fact that our body is able to store excess of D3 in the fat cells, when there is too much of it, D3 has an ability to attach to the T-cell receptors - blocking the normal action of T-cells (thymus) that are necessary for our immune system to work well. As a result of that, symptoms of various diseases can be also temporary suppressed (as it is case with taking corticosteroids), but in long term - chronic diseases develop and become obvious as soon as person stops using D3 supplements.


4. Vitamin D2 (ergosterol, calcidiol) is derived from fungus (mushrooms or yeast (that have been exposed to UV light). It is not so bioactive as D3, because human body has to transform it into D3 in order to use it, but is stil powerfull substance. Today food we buy is often fortified with D2 (milk, butter, juices...), so if someone is additionaly using D2 supplements  it is very important to follow what are real amounts of vitamin D person is taking daily - recommended dosage should not be exceeded.


5. There is only one type of vitamin (hormone) D I will always recommend - that is sunshine. 15-30 minutes of daily exposure to the sunshine is able to balance all needs for D hormone in the body, at least that is required minimum...  The another very acceptable way of taking vitamin D - is as homeopathic remedy.


6, People who live live above 37 degrees latitude do not get vitamin D during the winter ( from October to March ), so during the winter they really need additional intake of vitamin D2 (in food, or fortified food or supplements), according to daily recommended dosage (400 UI) .


7. Sources of vitamin D in food are: cod liver oil, fatty fish, halibut, egg yolk, sweet potatoes, vegetable oils, alfalfa, and oatmeal, but intake of vitamin D through the food (or supplements) cannot permanently replace our need for sunlight. Our skin will be always the best factory of the best quality of vitamin D.


Supplements of vitamin D ? Not so good least not for everybody.

It is not every person able to absorb vitamin D from supplements
It is not every person able to absorb vitamin D from supplements


Nowadays is VITAMIN D DEFICIENCY(Hypovitaminosis D) a common problem. Due to the modern style of life and fear from negative effect UV sun rays, people spend very little time outside and their actual exposure to the sunlight is far below the needed minimum.

People who have kidney and liver diseases, as well as older people have additional problem with vitamin D synthesis.

Only reliable way to get enough of vitamin D is from the sun exposure, because our skin has the best capacity to produce hormone/vitamin D in our body. (only smaller amount of it should be obtained from food and supplements).

Vitamin/hormone D - when in right quantity, is necessary:

  • for metabolism of calcium and phosphorus (it directly interacts with parathyroid hormone - PTH- of parathyroid glands, it promotes absorption of calcium and phosphorus from food in the intestines, and re- absorption of calcium in the kidneys)
  • for mineralization and growth of the bones and teeth (during the whole life)
  • for health of the kidneys and intestines
  • for improving immune system
  • it has strong anti-oxidant properties and activates regeneration of cells and cellular death of tumor cells


There are two types of imbalance of vitamin/hormone D possible:

  1. Hypovitaminosis D, caused by lack of vitamin D
  2. Hypervitaminosis D, caused by excess of vitamin D


1. Hypovitaminosis D (low level of vitamin D) today have many people of all age, actually more then ever: lack of outdoor activities has it´s high cost for health. As a result of that, people suffer from:

  • too high level of PTH (parathyroid hormone)
  • osteoporosis,
  • osteomalacia (softening of the bones)
  • increased risk of fractures
  • gum diseases
  • inability to absorb calcium and phosphorus from food
  • low immunity
  • musculoskeletal pain,
  • fatigue,
  • gum bleeding,
  • depression (especially seasonal), irritability,
  • appetite disorders,
  • foggy mind, lack of concentration


2. Hypervitaminosis D (vitamin D poisoning), is occuring because of overuse of vitamin D supplements during the longer period of time, and can happen more often then people are aware. Hypervitaminosis D causes:

  • high blood concentrations of calcium (hypercalcemia),
  • overcalcification of the bones, soft tissues, heart and kidneys
  • damage the kidney
  • produces kidney stones
  • hypertension
  • problems with immunity

Symptoms of excess of vitamin D are:

  • Constipation, decreased appetite (anorexia), dehydration, fatigue, irritability, muscle weakness, vomiting


As you can see, it is so easy to mix symptomes of lack or excess of vitamin D: fatigue, irritability, low appetite and problems with muscles and pain can happen in the both cases...(and also can be symptoms of million other health conditions...)  

. ..


Vitamin D is very powerful hormone... We cannot be healthy neither without it, nor with excess of it.

Although vitamin D can be useful in healing various autoimmune diseases for some people and has strong anti-oxidant properties so can be great as tumor prevention , it is far for being ultimate cure for them - at least not in supplements. What is good for one person, it does not need to be good for the other. Taking massive doses of vitamin D will not cure any disease - it will just cause new problems.

So - let more sunshine in your life... and do it consciously, while enjoying in sunrays: your skin and your body is the best possible and most reliable creator of vitamin D...
