The richest natural source of vitamin D is sunlight, which your skin produces, but fatty fish (like salmon, herring, mackerel) and fish liver oils are the best food sources, with fortified foods (milk, cereal) and UV-exposed mushrooms also being good options; egg yolks and cheese offer smaller amounts.
The foods highest in vitamin D are fatty fish (salmon, mackerel, sardines, tuna) and fish liver oils (like cod liver oil), with egg yolks, beef liver, and UV-exposed mushrooms also containing significant amounts, but most people get vitamin D from fortified foods like milk, cereals, and juices.
Few foods naturally contain vitamin D. The flesh of fatty fish (such as trout, salmon, tuna, and mackerel) and fish liver oils are among the best sources [17,1].
Yes, vitamin D deficiency can be linked to itchy rashes, especially conditions like eczema (atopic dermatitis) and psoriasis, because vitamin D helps regulate the immune system and skin barrier, while low levels can increase inflammation and susceptibility to skin issues. Research shows a connection between low vitamin D and various itchy skin problems, including hives (urticaria) and general rashes, with supplementation sometimes improving symptoms.
For pregnancy, the best vitamin D supplement is typically Vitamin D3 (cholecalciferol), as it's more effective at raising blood levels than D2, with studies suggesting higher doses like 4000 IU daily may be needed for sufficiency, though a doctor should guide your specific dosage after a blood test, as too little is risky but excessive amounts (over 100 mcg or 4000 IU) can be harmful.
However, when the researchers compared pregnancy outcomes across a wider range of vitamin D concentrations, they found that pregnant women with first trimester vitamin D concentrations lower than 40 nmol/L were four times more likely to experience a preterm birth compared to women with vitamin D concentrations more ...
To quickly increase Vitamin D, combine safe sunlight exposure (10-20 mins daily without sunscreen for lighter skin), taking high-dose Vitamin D3 supplements (consult a doctor first), and eating foods like fatty fish (salmon, tuna), egg yolks, fortified milk/cereals, and sun-exposed mushrooms, ensuring you take supplements with a fat source for better absorption.
Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.
The correlation between Vitamin D deficiency and decreased sleep duration as well as impaired sleep efficiency has been well-documented in several studies.
Our bodies produce active vitamin D after exposure to sunlight, and we get some vitamin D from food. Vitamin D is also a hormone. Hormones help control how cells and organs function. However, we do not call vitamin D “hormone D” because without it we cannot live.
Mushrooms: Certain mushrooms, such as maitake, morel, and shiitake, can produce vitamin D when exposed to sunlight. When fresh button mushrooms are deliberately exposed to the sun during midday for a duration of 15 to 20 minutes, they can produce significant amounts of vitamin D2.
Fatty fish (like trout, salmon, tuna, and mackerel) and fish liver oils are among the best natural sources of vitamin D. Beef liver, egg yolks, and cheese have small amounts of vitamin D. Mushrooms provide a little vitamin D. Some mushrooms have been exposed to ultraviolet light to increase their vitamin D content.
“Check the current USDA label on a carton of eggs and it will show that having that two-egg omelet provides 22 percent of the recommended daily allowance for vitamin D.
Egg yolks
So skip the egg-white-only scramble if you're going for vitamin content. How much? One large egg yolk contains around 41 IUs of vitamin D, or roughly 5% of the recommended daily value. Try this: A veggie omelet with mushrooms (more on those below!)
Avocado oil, linseed oil, olive oil, pumpkinseed oil, rapeseed oil, soya oil, sunflower oil, and wheat germ oil (WGO) were used to characterize and quantify their vitamin D precursors and metabolites.
The best sources are the flesh of fatty fish and fish liver oils. Smaller amounts are found in egg yolks, cheese, and beef liver. Certain mushrooms contain some vitamin D2; in addition some commercially sold mushrooms contain higher amounts of D2 due to intentionally being exposed to high amounts of ultraviolet light.
Supplementing vitamin B6 may improve sleep quality and duration. A 2019 study also found that taking a supplement of magnesium, melatonin, and vitamin B complex for 3 months improved sleep and helped treat insomnia.
Yes, you can do a vitamin D test at home using simple finger-prick kits (like TouchBio, 2San, We Test Bio) that provide quick, preliminary results (often in 10 mins) by analyzing a drop of blood to check if levels are sufficient, insufficient, or deficient, helping you monitor bone health and immune support, but you should always discuss abnormal results with a doctor for proper diagnosis and treatment.
Medical conditions like insomnia, sleep apnea, restless legs syndrome, anxiety and depression, and indigestion, as well as some medications can cause frequent nighttime wakings. Your bedroom environment—temperature, noise, light, discomfort—and lifestyle factors like alcohol or caffeine consumption can also contribute.
In children, it can cause rickets. Rickets is a rare disease that causes the bones to become soft and bend. African American infants and children are at higher risk of getting rickets. In adults, severe vitamin D deficiency leads to osteomalacia.
These studies consistently show that elevated vitamin D from sunlight is associated with improved physical, mental and immune system function. Yet vitamin D supplementation studies don't show the same health effects.
Dry mouth (xerostomia) can be caused by deficiencies in nutrients like Vitamin B12, Iron, Zinc, and Vitamin A, which are crucial for nerve health, mucous membranes, and saliva production, but it's often linked to dehydration, medications, diabetes, or other conditions, so seeing a doctor for proper diagnosis is essential.
Although the list of foods naturally high in vitamin D is a short one, there are foods and beverages – like milk, orange juice, nutritional shakes and breakfast cereals fortified with the nutrient to help make life a little easier!
Symptoms when vitamin D is low
Fatigue. Not sleeping well. Bone pain or achiness. Depression or feelings of sadness.
The fastest way to increase vitamin D is usually through high-dose supplements prescribed by a doctor for a deficiency, combined with moderate, safe sunlight exposure and incorporating fortified foods like milk/yogurt and foods rich in D like fatty fish (salmon, tuna) and eggs, but always consult a doctor first for proper levels and dosage.
