The Best Sources & The Importance Behind it
Fun fact about Vitamin D – it’s a hormone! Your body can make Vitamin D upon sun exposure, and when in active form, it is considered to be a hormone.
Vitamin D (fat-soluble) is essential for regulating cell growth and prevents a host of illnesses. It also plays a central role in improving the absorption of crucial nutrients and vitamins.
Fat-Soluble VitaminsFat-soluble vitamins such as A, D, E, and K stay in your body for a more extended period. Most fat-soluble vitamins are stored in fat (hence their name) while some are stored in the liver and other organs.
Studies have shown individuals that live sedentary lifestyles have a higher risk of deficiency due to less sunlight exposure.
About 77% of Americans have insufficient levels of Vitamin D.
Vitamin D2 & D3
There are two essential forms of Vitamin D; D2 and D3.
D3 comes from animal-sourced foods.
The richest sources of D3 are in fatty fish, fish oils, egg yolks, liver, and grass-fed butter.
D2 comes from some plant sources.
D2 is cheaper to produce and is most commonly found in fortified foods and supplements.
Ways to Acquire more D2 & D3
- Eat more fatty fish
- Eat egg yolks and grass-fed butter
- Spend more time in the sun daily
- Take fish oil supplements
While a Paleo diet and lifestyle provide the bulk of your nutrients, you may not be getting your full daily dose. Read more about supplementing here.
I encourage you to talk to your healthcare provider about the use of dietary supplements and what may be best for your overall well being before changing your health plan. In the meantime, continue to get adequate sunlight and eat plenty of foods rich in D3.
