The Importance of Vitamin D

Here we are, nearing the end of flu season. Or are we? If you live in the Northeast United States, chances are your blood levels of Vitamin D3 are a bit low. If so, studies indicate you might be more susceptible to viral infection, including the flu, than if your Vitamin D3 blood values were within range. And this means even if flu season ends according to the calendar, you might be set up for another viral infection as springtime approaches.

(Note: Before beginning to take any supplements, including Vitamin D, speak with your healthcare provider. Reading about it in an article, or seeing a video does not mean it is the right intervention for your unique body. Many things need to be considered in order to responsibly prescribe any supplement.)

Wondering what you can do to protect yourself right off the bat today, without asking your doctor’s permission? Read on. Among the things you can do to protect yourself are good hand washing, particularly before and after food preparation and eating, sneezing and coughing appropriately (into your elbow rather than into your hand or behind your fist), and drinking plenty of healthful fluids (such as organic bone broth and, if your doctor permits: green tea). Things to avoid include sugar, white flour, and any foods that have “partially hydrogenated,” “modified,” “corn syrup,” and/or “artificial” on the label. There is indeed much you can do to protect yourself.

Luckily, your body is designed to heal itself. There are steps to take to help it, and other steps that get in the way. In addition to the above-mentioned recommendations, you might ask your doctor if Vitamin D might be worthwhile to consider. Do not begin a Vitamin D regimen on your own since there are different forms (D2 and D3) and amounts that need to be decided upon from a health provider’s perspective. Your doctor will take your age, medications, and diet into consideration when prescribing this supplement, if indeed this intervention is deemed appropriate. Keep in mind that, before incorporating any changes to your diet or lifestyle (including supplements, foods, and even exercise) you should speak with your primary healthcare provider. Here’s to your best health and wellness.
