 The Link Between Vitamin D and your Immune SystemVitamin D is often referred to as the sunshine vitamin because your body produces the vitamin when exposed to sunlight.

This essential vitamin is most often associated with bone health because it plays an important role in protecting your bones. Without vitamin D, your body can’t absorb bone-critical calcium, which would put you at risk of lower bone density and bone loss.[1]

But the health benefits of vitamin D extend way beyond your bones.

Research has found vitamin D can help lift your mood, particularly during the dark winter months[2]. It has also been shown to promote heart health[3] and to help regulate blood pressure[4]. Low levels have been associated with joint discomfort.[5]

Most recently, research has uncovered a direct link between vitamin D and immunity.

A group of researchers analyzed 25 randomized controlled trials that explored vitamin D’s impact on immunity. These studies included 11,000 participants from more than a dozen countries, including the United States, Canada, and the U.K.

The term discovered higher levels of vitamin D were associated with better overall health during the winter months when the immune system is most at risk to be compromised.

The researchers also found that adults with low vitamin D could boost their immunity and cut their risk of developing seasonal illnesses in half if they took vitamin D supplements daily or weekly. Taking occasional high doses of vitamin D did not provide significant benefits.[6]

Low vitamin D is a concern for children and adults. More than 80 percent of children ages 2 to 8 and 98 percent of girls 14 to 18 are vitamin D deficient, according to studies.[7] A 2014 report from the Environmental Working Group found 95 percent of American adults are deficient in vitamin D.[8]

Unfortunately, it’s nearly impossible to maintain adequate vitamin D through diet alone. Unlike most vitamins, vitamin D is not naturally present in many foods. Although cod liver oil, salmon, mackerel, tuna, beef liver, cheese and egg yolks have small amounts, it’s not enough.

Of course, you can get vitamin D from sunlight. But you need to be exposed without sunblock, and that comes with its own risks.

 

Taking supplements is one of the easiest ways to maintain your vitamin D. It’s important to read the labels, though, because there are two forms: D3 (cholecalciferol) and D2 (ergocalciferol). D3 is more effective and potent than D2, according to research. In fact, one study found D3 was 87 percent more potent than D2 in humans.[9]

Rainbow Light has developed a tasty line of vitamin D gummies to support your bones, heart, immune system and overall health. For adults, Berry D-Licious Vitamin D3 are raspberry-flavored gummy drops that provide an ultra-potent 2,500 IU of vitamin D3 in each daily dose for ultimate health support. That’s six times the recommended dietary allowance for adults! And for kids, Sunny Gummies provide 400 IU in each delicious orange-flavored gummy — 100 percent of the recommended allowance for kids and adolescents.*
