With the shorter days during autumn and winter months, combined with cooler temperatures (depending on where you live!) and the propensity to stay inside, we experience fewer and fewer hours of sunlight exposure. How is this important to your health?

Shining a Light on D3

Aside from the role sunlight and spending time outdoors plays in our well-being,1 sunlight is critical for the formation of a specific vitamin that is difficult to get nearly anywhere else - Vitamin D.

Vitamin D3 is created when our skin is exposed to sunlight, and a chemical reaction takes place resulting in increased levels of this fat-soluble nutrient. Layered clothing, daily use of sunscreens, and increased time spent indoors all contribute to falling numbers of this vitamin throughout the US. In fact, 66 million Americans suffer from a Vitamin D3 insufficiency, which equates to one in five people!2 This is especially noticeable in higher latitudes, where days tend to be even shorter, and winters even colder.

Vitamin D3 supports many vital processes in the body, including the development and maintenance of bones and teeth, the absorption of calcium and other minerals, the overall function of our cells, and much more! Another area where Vitamin D3 shines is promoting the healthy functioning of our immune system.* Vitamin D is thought to increase our resistance to seasonal immune challenges,3 so having optimal levels becomes especially important during the winter season, which unfortunately tends to coordinate with increased time spent indoors.

Gotta Catch it All!

MegaFood Vitamin D3 2000IUSo how can you ensure you’re getting enough Vitamin D3? First, work with your healthcare practitioner to test your D3 levels to see where they are at. According to our friend and MegaFood Chief Medical Advisor Dr. Tieraona Low Dog, those with light skin may need as little as 10 minutes in the sun three or four times a week, whereas those with darker complexions may need one to two hours.4 In addition to spending extra time outdoors, consider supplementing with quality vitamin D3 as needed. Taking a foundational multivitamin that contains it is an important first step, however those that require increased supplementation should consider an add-on formula to ensure they are getting enough.

We offer Vitamin D3 tablets in two different potencies - 1000 IU and 2000 IU - so that you can pick the amount of supplementation that is right for you! In addition we have a delicious D3 Wellness Gummy, that provides 1000 IU per serving and is made with farm fresh oranges, cranberries and blueberries to give them a distinctive, real fruit flavor (and natural color!)* Only 1 gram of sugar or less per serving! All of our options are non-GMO, gluten, dairy and soy-free, plus tested for 125+ pesticides and herbicides and certified glyphosate residue free.

We all have different needs, so be sure to work with your healthcare practitioner to determine yours. IF you find you’re in need of additional Vitamin D3 support, MegaFood has your back!
