What is Vitamin D?
Often referred to as the “sunshine vitamin,” vitamin D is a steroid vitamin, a fat-soluble prohormone best known for its role in supporting bone health and aiding in the absorption of calcium and phosphate from the GI tract.
But the benefits of vitamin D (aka vitamin D3, which is also known as cholecalciferol) far surpass the traditional view of its role in maintaining healthy bones. In fact, the active form of vitamin D3 in the body functions as a hormone, and nearly every tissue in the body has a vitamin D receptor, including cells of the pancreas, immune system, skin, thyroid, stomach, colon, and more.
Along those lines, a growing body of research sheds light on what vitamin D is good for, highlighting its important role in supporting other body systems, including the cardiovascular system, blood sugar balance, musculoskeletal strength, cognitive function, and immune function, which trace to its ability to target over 200 different genes in the body.
What is Vitamin D Good For?
When it comes to the benefits of vitamin D3, it is best known for its role in assisting with proper bone health, as it helps regulate the body’s calcium levels. When calcium levels are low, for example, vitamin D stimulates calcium absorption and reduces calcium excretion, thereby encouraging healthy bones and teeth.
In addition, vitamin D helps support a balanced immune response in the body. For example, sufficient levels of vitamin D are needed to support a healthy, properly functioning immune system, as vitamin D plays important roles in both the body’s innate and adaptive immunity.
Vitamin D also enhances healthy cell replication and division and supports metabolic health, including healthy glucose metabolism. Vitamin D also has many other roles in the body, such as providing support for healthy muscular function and cognitive health.
For example, vitamin D receptors and pathways have been found in areas of the brain involved in both memory and cognition. Along those lines, two cross-sectional trials involving more than 300 older individuals indicate that higher levels of vitamin D are associated with positive mood and mental performance.
What’s more, a healthy vitamin D status may also be important for cardiovascular health, as higher vitamin D levels have been associated with healthy blood vessel relaxation and blood flow. Research also indicates that vitamin D may help promote nerve health by supporting immune function, nerve conduction potential and antioxidant defense.
Why Are So Many Americans Low on Vitamin D?
Unfortunately, hardly anyone has healthy levels of vitamin D according to the definitions provided by the Endocrine Society:
- Vitamin D deficiency: 25(OH)D < 20 ng/mL
- Vitamin D insufficiency: 25(OH)D < 30 ng/mL
Respected vitamin D scientists and doctors as well as the Endocrine Society suggest that 25(OH)D between 40 and 60 ng/mL is the preferred range for health. Shockingly, scientific studies reveal that about 1 BILLION people worldwide have vitamin D deficiency, while 50% of the population has vitamin D insufficiency.
The bottom line is that vitamin D deficiency is the most common health concern worldwide.
Why are so many people low on vitamin D? Well, our primary vitamin D source is exposure to sunlight, which contains ultraviolet rays that produce cholecalciferol (the scientific name for vitamin D3) in the skin.
But guess what? Most people don’t get nearly enough sunshine (with their bare skin exposed). At a minimum, people with fair skin need to spend about 15 minutes in the sun with the face, arms, and legs exposed (NO SUNSCREEN) several times a week between the hours of 11 a.m. and 3 p.m. to obtain the bare bones necessary levels of vitamin D3.
Of course, for many people, that really only applies for about six to eight months out of the year. After all, if you live above or below 33 – 37° latitude, very little, if any, cholecalciferol can be produced in the skin from sun exposure from November through April.
After all, where you live, the time of year, and the time of day all influence the amount of the sun’s UVB rays that enter the earth’s atmosphere. For example, levels of UVB rays are all dramatically lower (thus lowering your ability to make vitamin D3 from the sun and increasing the likelihood of vitamin D deficiency):
- Earlier and later in the day (11 a.m. to 3 p.m. is prime time)
- During most of the day during the winter (If you live in New York or Boston, forget trying to produce any vitamin D3 naturally from November through March.)
- The further you are from the equator (i.e., higher latitudes) (If you live in Canada, you’re not going to be able to produce much cholecalciferol from October through April.)
If you have darker skin, you need even more time—up to a couple of hours—in the sun to boost your levels of vitamin D. Here’s another layer of complexity: As you get older, your body has a harder time producing vitamin D3, making vitamin D deficiency more likely. For example, aging reduces cholecalciferol production in the skin by as much as 50%.
Although vitamin D deficiency is present among all age groups, it is especially prevalent among women after menopause, possibly due to poor exposure to sunlight and insufficient intake of vitamin D from the diet. Additionally, several commonly used medications can impair the body’s production and/or absorption of vitamin D.
A vitamin D supplement, therefore, may be especially important for a wide range of folks.
The Problems with Some Vitamin D Supplements
So, we’ve established that inadequate sunlight exposure is a HUGE problem. However, there’s still good news… certain foods contain vitamin D. Unfortunately, there are very few natural dietary sources of vitamin D3, and they include fatty fish, liver, and eggs.
If you’re a plant-based eater, your only dietary source is mushrooms, which contain vitamin D2, a form of the vitamin that the body has to convert (not very efficiently) into the more bioactive cholecalciferol form. Vitamin D2, often considered an inferior form, is also the form that is most commonly used in fortified foods.
And even if you’re eating some of these foods regularly, you’d still be missing the boat. For instance, one whole egg has only 41 IU of vitamin D, and a cup of typical store-bought mushrooms has less than 10 IU.
What’s more, there can be digestive issues at play (e.g., malabsorption), and certain types of dietary fats might interfere with absorption. What’s more, low magnesium intake might also lead to insufficient levels of vitamin D. Finally, several commonly used medications may interfere with vitamin D3 absorption.
Considering many people aren’t getting the non-burning sun exposure they need, few foods contain vitamin D, and the various health and environmental issues at play, using a vitamin D supplement is just plain smart. And it’s what’s recommended by top scientists, doctors, and the world’s leading authorities on vitamin D.
But there’s ANOTHER problem—actually several of them—when it comes to finding the best vitamin D3 supplement…
Source of vitamin D: Studies have shown that vitamin D3 (cholecalciferol, which is the form of vitamin D synthesized in humans and animals, such as fish) is substantially more effective—up to 3 TIMES as much—at elevating levels of vitamin D in the body compared to vitamin D2 (ergocalciferol), the form of vitamin D found in plants.
Bottom line: The best vitamin D supplement features high-potency, clinically-useful levels of vitamin D3.
Missing its teammate: Vitamin K, assists in calcium metabolism, in which vitamin D’s also plays a crucial role. For example, vitamin D stimulates increased absorption and retention of calcium, and vitamin K performs the important function of directing the calcium where to go: It helps deposit it where it’s needed, such as in bones and teeth. Along those lines, a meta-analyses found that a combination of vitamin K and D was helpful in supporting bone health among a sample of 971 participants.
Because of the synergy between vitamin D and vitamin K, we believe it's important to combine the two in one product.
Delivery: Many vitamin D supplements come in liquid form, and you have to use a dropper to administer it. Unfortunately, these preparations are often highly unstable, resulting in a decrease in vitamin D3 content. For example, one study examining 16 different vitamin D supplements found that more than two-thirds had a vitamin D3 content that was <90% of the amount on the label. This is because the stability of these liquid preparations can be influenced by oxygen, temperature, humidity, and light exposure, leading to a significant decrease in vitamin D content. Another complication with liquid droppers is not necessarily knowing how much you’re getting (i.e., if you’re getting too much/too little).
Bottom line: We believe it's important that a vitamin D3 supplement comes in softgel form.
Bioavailability: Vitamin D3 is a fat-soluble compound, which when ingested, is emulsified by the bile salts and is absorbed by intestinal enterocytes. The absorption efficiency, or bioavailability, depends on a variety of factors. Shelf-stable softgels can help protect delicate fat-soluble nutrients like vitamin D and help them get where they need to go in the body, ultimately helping optimize bioavailability.
Bottom line: We believe in using softgels to help optimize absorption of vitamin D.
Third-party testing: Another problem with many vitamin D supplements is that they are not third-party lab tested to ensure purity, potency, and safety.
Bottom line: The best vitamin D3 supplement is third-party tested to ensure purity, potency, and safety.
