Did you know that Vitamin D deficiency is very common (like almost half of Americans)? Most people simply don’t spend enough time outdoors anymore, and it’s also not superabundant in many foods either, although many are fortified. A recent study in Spain found that out of 200 Covid-19 patients, 80% of them were deficient in Vitamin D. Yikes.
What exactly is Vitamin D?
Vitamin D is a fat-soluble vitamin that is essential for bone health and calcium absorption. There are two important forms: D2 (mainly found in plant sources and fortified foods) and D3 (only found in animal food sources).
What does Vitamin D do for me?
Enables our bodies to absorb and regulate calcium
Builds and maintains healthy bones and adequate bone density
Reduces risk of rickets in children and osteomalacia and osteoporosis in adults
Helps reduce inflammation
Influences cell growth, neuromuscular function, and glucose metabolism
Promotes immune health
Improves cardiovascular health and lessens the risk of cardiovascular disease
What are some symptoms of Vitamin D deficiency?
Bone pain
Pain and weakness in joints/muscles/connective tissue
Fatigue/weakness
Depression
Poor immunity/frequent colds
Chronic illnesses/cancer
Who is at greatest risk of Vitamin D deficiency?
Breastfed infants (sorry anti-formula moms, at least take your supplements)
The elderly
Those with very limited sun exposure
Those with dark complexions (more melanin actually limits the body’s ability to produce Vitamin D from sun exposure!)
The obese (greater amounts of subcutaneous fat tend to sequester or “hide away” Vitamin D that could otherwise be used from sunlight exposure)
Those who have issues absorbing and digesting fats, or limit dairy
How can I get more Vitamin D?
Get some sun.
Eat adequate Vitamin D in the diet.
Consider a supplement (general RDA for infants is 400 IU, children and adults ages 1-70 is 600 IU, and older adults 71+ is 800 IU) .
Maintain a healthy weight.
What are some food sources rich in Vitamin D?
Cod liver oil
Fatty fish (i.e. trout, salmon, mackerel, sardines, herring)
Mushrooms exposed to UV sunlight
Vitamin D fortified foods and milks
One should note that Vitamin D supplements can interact with certain drugs, such as:
Orlistat (Xenical® and alli®)
Statins (Lipitor®), Altoprev®, Mevacor®, FloLipid™, and Zocor®)
Steroids (Deltasone®, Rayos®, and Sterapred®)
Thiazide Diuretics (Hygroton®, Lozol®, and Microzide®)
Always talk to your doctor before taking supplements if you are on medication.
So, take some dietary inventory, check your vitamin bottle label, and get regular lab work done. If it looks like you may need more vitamin D and are experiencing some signs of a deficiency, it’s time to make some changes. This is not one to take lightly!
