Vitamin D

🏫Back to school - keeping those kiddos healthy. VITAMIN D.
.
The Journal of the American Osteopathic Association published the results of a study that showed that 1 billion people worldwide (about 1 in 7 people) are deficient in vitamin D. For Americans, it's around 40%. (1, 2)

There are 3 ways to get vitamin D:

1️⃣The sun. Vitamin D is often referred to as the "sunshine vitamin" because your body makes vitamin D when it is exposed to the sun. Getting enough of a daily dose is hugely important for overall health. Your body can produce 10,000 to 20,000 IUs of vitamin D after a short amount of time in the sun in the right conditions, with full exposure (don’t get pink or burn).
.
2️⃣Food. A smaller portion of vitamin D comes from food. Here are some foods that are a source of vitamin D:

Cod liver oil (1,360 IU per tablespoon)
Salmon (988 IU per 3.5 ounces)
Sardines (272 IU per 3.5 ounces)
Tuna (154 IU per 3 ounces)
Egg yolk (41 IU per yolk)
Yogurt (80-100 IU per 6 ounces)
Almond milk (100 IU per 8 ounces)
Cows milk (130 IU per 8 ounces) (3)

3️⃣Take a vitamin D3 supplement. Shown above are 2 of my favorites. When purchasing a liquid vit D, there are only 2 or 3 ingredients needed. The vit D, and MCT oil (possibly with an olive oil too), and vit k. Check to see if your vit D has other unnecessary fillers.

👉🏻Why is vitamin D so important? .
“Vitamin D deficiency is associated with increased autoimmunity as well as increased susceptibility to infection.” It’s crucial to have enough vitamin D because it assists with cell replication. (4)

A meta-analysis study of more than 11,000 participants was published in the British Medical Journal (funded by a grant from the NIH) and found that vitamin D reduces the risk of respiratory infection—including colds & flu. The study’s senior author, Carlos Camargo, stated that “vitamin D helps the body fight acute respiratory infection.” (5,6)
