Symptoms And Health Risks Of Vitamin D Deficiency
However, for many people, the symptoms are subtle. Yet, even without symptoms, too little vitamin D can pose health risks. Low blood levels of the vitamin have been associated with the following: Increased risk of death from cardiovascular disease
Cognitive impairment in older adults
Severe asthma in children
Cancer Research suggests that vitamin D could play a role in the prevention and treatment of a number of different conditions, including type1 and type 2 diabetes, hypertension, glucose intolerance, and multiple sclerosi.

Whether the salmon is wild or farmed can make a big difference. Some studies have found even higher levels in wild salmon — up to 1,300 IU per serving Summary Wild salmon contains about 988 IU of vitamin D per serving, while farmed salmon contains 250 IU, on average.
That’s 124% and 32% of the DV, respectively.

These nutrients are needed to keep bones, teeth and muscles healthy. Government advice is that everyone should consider taking a daily vitamin D supplement during the autumn and winter.
People at high risk of not getting enough vitamin D, all children aged 1 to 4, and all babies (unless they’re having more than 500ml of infant formula a day) should take a daily supplement throughout the year. But there is currently not enough evidence to support taking vitamin D solely to prevent or treat COVID-19.
How Much Vitamin D Should You Be Getting?
In” because it’s produced within the body when the sun hits the skin.
Decreasing vitamin D levels isn’t just a winter issue. Over the past couple of decades, the number of Americans with sufficient levels has decreased. “Adults achieving vitamin D sufficiency has dropped from 60 percent in the early 1990s to 30 percent in the early 2000s,” says Kerry Clifford, a registered dietitian who works for the National Dairy Council, citing a past study of Centers for Disease Control and Prevention (CDC) data.

Definitions of exactly what vitamin D deficiency means vary from less than or equal to 12 nanograms per milliliter (12 ng/mL) to less than or equal to 20 ng/mL on the high end. Those who are nonwhite, obese, or without a college education are at greater risk of not having adequate vitamin D levels. (2)
Drinking less milk (a beverage that has been fortified with vitamin D since the 1930s) and using sunscreen are among the reasons that Vitamin D status in Americans has dropped over the years, says Clifford.

That drop is a problem because the vitamin can help the gut absorb calcium, which ultimately promotes strong and healthy bones.
