You may be surprised to learn that vitamin D is completely different from most other vitamins.
It is actually a hormone, a steroid hormone that is produced out of cholesterol when your skin is exposed to the sun.
For this reason, vitamin D is often referred to as the “sunshine” vitamin.
However, sun exposure is often inadequate these days, making it necessary for people to get more of it from the diet (or supplements).
This is important, because vitamin D is absolutely essential for optimal health (1).
In fact, according to data from 2005-2006, a whopping 41.6% of the US population is deficient in this critical vitamin/hormone (4).
This article explains everything you need to know about vitamin D.
What is Vitamin D?
Vitamin D is one of the fat-soluble vitamins (A, D, E and K), meaning that it dissolves in fat/oil and can be stored in the body for a long time.
There are actually two main forms found in the diet (5):
- Vitamin D3 (cholecalciferol): Found in some animal foods, like fatty fish and egg yolks.
- Vitamin D2 (ergocalciferol): Found in some plants.
Bottom Line: Vitamin D is a fat-soluble vitamin that can be stored in the body for long periods of time. There are two main forms, D2 and D3, of which D3 is much more effective.
What Does Vitamin D Do in The Body?
Vitamin D is actually pretty useless at first.
Second, it is converted to calcitriol, or 1,25(OH)2D, mostly in the kidneys. This is the active, steroid hormone form of vitamin D.
Calcitriol travels around the body, going into the nuclei of cells. There it interacts with a receptor called the vitamin D receptor (VDR), which is found in almost every single cell of the body (10, 11).
It is well known that vitamin D affects various cells related to bone health, for example telling the cells in the gut to absorb calcium and phosphorus (14).
So people who are deficient in vitamin D will be deficient in calcitriol (the steroid hormone form), so in effect they are deficient in one of the body’s critical hormones.
Bottom Line: Vitamin D is turned into calcidiol, the storage form of the vitamin, which is then converted into calcitriol, the active steroid form. Calcitriol binds to the vitamin D receptor inside cells, turning genes on or off.
Sunshine is The Best Way to Get Vitamin D
If you live where there is abundant sun year round, then you can probably get all the vitamin D you need by just going outside and sunbathing a few times per week.
Also, if you stay behind glass or use sunscreen, then you will produce less vitamin D, or none at all.Keep in mind that you need to expose a large part of your body. If you’re only exposing your face and hands then you will produce much less vitamin D.
This makes the advice to use sunscreen to protect against skin cancer highly questionable. It raises your risk of vitamin D deficiency, which may lead to other diseases instead (17).
If you decide to get your vitamin D from the sun, just make sure to never, everburn.
If you’re staying in the sun for a long time, consider going without sunscreen for the first 10-30 minutes or so (depending on your sensitivity to sun), then apply it before you start burning.
Vitamin D gets stored in the body for a long time, weeks or months, so you may only need occasional sun to keep your blood levels adequate.
All that being said, not everyone (including myself) lives where there is sun year round. In these cases, getting vitamin D from foods or supplements becomes absolutely essential, especially during the winter months.
Bottom Line: Sunshine is the best way to get vitamin D, but sunscreen blocks its production. Many people don’t have access to sunshine for most of the year.
Very Few Foods Contain This Vitamin in Significant Amounts
Some rare mushrooms also contain vitamin D, and egg yolks contain small amounts.
Bottom Line: Cod fish liver oil is the single best source of vitamin D3. Fatty fish is also a good source, but you have to eat it very often to get enough.
Vitamin D Deficiency is Serious Business
Vitamin D deficiency is one of the most common nutrient deficiencies.
Some people are at greater risk than others. Although the average is around 41.6%, this percentage goes up to 82.1% in black people and 69.2% in Hispanics (4).
Elderly people are also at a much greater risk of being deficient (22).
People who have certain diseases are also very likely to be deficient.
One study showed that 96% of heart attack patients were low on vitamin D (23)
Unfortunately, vitamin D deficiency is a silent epidemic. The symptoms are usually subtle, and may take years or decades to surface.
The most well known symptom of vitamin D deficiency is a disease of the bones called rickets, which is common in children in developing countries.
However, due to public health measures back in the day, they started fortifying some foods with vitamin D, which mostly eliminated rickets from Western societies (24).
Studies have also shown that people with low vitamin D levels have a much greater risk of heart disease, diabetes (both type 1 and type 2), cancer, dementia and autoimmune diseases like multiple sclerosis, to name a few (26).
Whether being vitamin D deficient actually contributes to these diseases, or whether people who have low vitamin D levels are just more likely to get them, is not as clear.
Bottom Line: Vitamin D deficiency is a well known cause of a bone disease called rickets in children. However, deficiency has also been linked to many other health problems, as well as reduced life expectancy.

Health Benefits of Getting Plenty of Vitamin D
Vitamin D has received considerable mainstream attention in recent years and decades.
Research on it has gotten lots of funding, and hundreds of studies have been done.
Here are some potential benefits of getting plenty of vitamin D:
- Osteoporosis, falls and fractures: Higher doses of vitamin D can help prevent osteoporosis, falls and fractures in the elderly (30).
- Strength: Vitamin D supplementation can increase physical strength, in both upper and lower limbs (31).
- Cancer: Vitamin D may help prevent cancer. One study showed that 1100 IU per day, along with calcium, reduced cancer risk by 60% (32, 33).
- Depression: Studies have shown vitamin D supplementation to cause mild reduction in symptoms in people with clinical depression (34).
- Type 1 diabetes: One study in infants found that 2000 IU of vitamin D per day reduced the risk of type 1 diabetes by 78% (35).
- Mortality: Some studies have shown that vitamin D supplementation reduces people’s risk of dying during the study periods, indicating that it may help you live longer (36, 37).
This is actually just the tip of the iceberg.
Low vitamin D levels have been linked to all sorts of diseases, and supplementation has been shown to have numerous other benefits.
However, keep in mind that much of this is not definitely proven. According to a recent 2014 review, more evidence is needed to confirm many of these benefits (38).
Bottom Line: Taking vitamin D supplements has been shown to have numerous benefits related to cancer, bone health, mental health and autoimmune diseases, to name a few.
How Much Should You Take?
The only way to know if you are deficient, and whether you need to take a supplement, is by having your blood levels measured.
Your doctor will measure the storage form, calcidiol or 25(OH)D. Anything under 12 ng/mL is considered deficient, and anything above 20 ng/mL is considered adequate.
The RDA for vitamin D in the US is as follows (39):
- 400 IU (10 mcg): Infants, 0-12 months.
- 600 IU (15 mcg): Children and adults, 1-70 years of age.
- 800 IU (20 mcg): Elderly and pregnant or lactating women.
Although the official cutoff point for vitamin D deficiency is 12 ng/mL, many health experts believe that people should aim for blood levels higher than 30 ng/mL for optimal health and disease prevention (40).
Additionally, many believe that the recommended intake is way too low, and that people need much more to reach optimal blood levels of the vitamin (41).
For people who are at risk of deficiency, this may be a good amount to aim for. Sometimes doctors recommend taking much more than that.
Just make sure to take vitamin D3, not D2.
Vitamin D3 capsules are available in most supermarkets and health food stores, and there is a good selection of vitamin D3 supplements on Amazon.
What Happens if You Take Too Much?
It is actually a myth that it is easy to overdose on vitamin D.
Vitamin D toxicity is very rare, and only happens if you take insane doses for long periods of time (43).
I personally live where there is very little sun year-round, so I take 4000-5000 IU per day of a vitamin D3 supplement.
I’ve been doing this for many years now, and consider it to be an essential component of my personal health strategy.
If you want to learn more, then I highly recommend the Vitamin D Council‘s website. They have a lot of evidence-based, high quality material on vitamin D.

You probably know most of us eat too much processed food. What you may not know is that it’s full of toxic chemicals and substandard, dirt-cheap ingredients designed to make you eat more…and force you to gain weight.
Here’s how it works...
“That stuff is just a lot of calories your body can’t use,” Liz told me, “Some are poison. And all these foods are stripped of the anti-oxidants and anti-inflammatories that help your body detox. The result? Your body expends huge amounts of calories to eliminate some toxins—the rest, it stores in your fat to protect you. This is why most people are hungry all the time. They’re not getting energy they need.”
“So… what’s going on with me? Why am I losing weight but not going hungry?”
Liz paused, then dropped the bombshell.
Your body is designed to burn fat. You just have to let it.
“What? I thought we were designed to store fat?!?” We were Skyping and I was practically shouting. Then I heard Liz say…
What good is a fat reserve if you can’t burn it?
Liz continued: “You’re drinking smoothies packed with phytonutrients, anti-oxidants and anti-inflammatories that pull toxins out of you like a tractor beam. Allowing your body to burn those toxin-filled fat stores… and releasing tremendous amounts of stored energy.”
So that’s why I’m losing weight without going hungry.
