Sources of Vitamin D – which are the best?
The seemingly magic benefits of Vitamin D for our health are well known by
now . But which are the best and most natural sources of vitamin D?
We make vitamin D from sunlight. To be more precise, vitamin D is made in our bodies when we expose the skin to UVB rays. This is the way nature intended us
We can take vitamin D with food and as food supplements. Vitamin D comes naturally in some kind of foods rich in vitamin D: Shiitake & Button Mushrooms, Cod Liver Oil, Mackerel, Salmon, Herring, Sardines, Catfish, Tuna fish. Eggs. Please note that we talk here about naturally (and preferably organic) grown food, not industrially farmed. Food can also be fortified with vitamin D. Even if vitamin D can be added to almost any kind of food, the most common
It is not easy to figure out how much
600 IU might be enough to avoid rickets and osteoporosis, which is still the only benefit of vitamin D that is officially recognized by the
If we want to reach the intake recommended by the vitamin D specialists, natural vitamin D rich food or food fortified with vitamin D is not a realistic way to get there. There is a practical limit to how much cod-liver oil we can drink or how much mushrooms, fish and eggs we can eat each day. The oral intake of vitamin D always was and still is, a complement to the main supply of vitamin D from sunlight.
In the wake of the discoveries of much more serious benefits of higher vitamin D levels than only to build strong bones, more and more vitamin D supplements are filling the shelves in drug-stores and
Today it is no problem to find vitamin D supplements with as much as 10,000 IU in one single pill. SOLGAR is a popular and
The problem with taking that much vitamin D orally is that we were never meant to get our main supply of vitamin D
Even many of the leading specialists on vitamin D hesitate to mention UV-exposure as the recommended source of vitamin D. This is mainly because they still are not sure if the adverse effects of UV-exposure, as we are being bombarded with through mass-media, are real or not. This has lead to an interesting development in the discussion about vitamin D levels. Instead of focusing on how high blood-levels of 25 (OH)D we really need to fight certain cancers and illnesses, the debate often concentrates on how much vitamin D3 is safe to take. And since nobody really knows the clinical long-term consequences from a permanent high oral intake of vitamin D3, this becomes a “Catch 22” moment in the vitamin D debate.
When we make vitamin D by exposing the skin to UVB rays, either from the natural sun or from the lamps in a tanning bed, the risk of getting too much vitamin D is not
The fact that vitamin D3 only (relatively) recently has been discovered as one of the potent substances made by sunshine in our skin, ought to make us

The companies that make vitamin D supplement pills are of course telling us that their supplements are the safest sources of Vitamin D. They are surfing on the anti-tanning wave invented by the manufacturers of sun-protection lotions and sun-scare lobbyists on their payroll.
The fact is that nature never intended pills to be among the sources of Vitamin D. The human body has evolved thanks to sunlight and the rays from the sun were and still are the most natural way for everyone to get good levels of this life-essential vitamin/hormone.
If sunlight could be fetched and sold by the bottle, sunshine would have had much stronger commercial support. Because UV-rays, and especially UVB-rays is the only real efficient source of Vitamin D.
But the truth is that tanning beds can be just as good, or even better, sources of Vitamin D than sunlight from the natural sun. As Dr. Michael Holick writes in his latest book “The Vitamin D Solution: A 3-Step Strategy To Cure Our Most Common Health Problems“:
“A UVB photon (packet of energy) is a photon whether it is produced by the sun or by a tanning bed with fluorescent lamps.”
This means that the two best sources of Vitamin D are the sun and tanning beds.
If there are still any doubts that you can get Vitamin D from a tanning bed, the compilation of research reports as below, made by Ad Brand, Scientific Advisor to the European Sunlight Association, will for sure scatter any doubts that tanning beds are excellent sources of Vitamin D.
