It\u2019s also naturally found in some foods and artificially added to others. Not getting enough sunlight and not eating enough vitamin D-rich foods can contribute to a vitamin D deficiency.\u00a0<\/span><\/p>\n<h2 id=\"what-are-the-most-common-symptoms-of-vitamin-d-deficiency\"><span style=\"font-weight: 400;\">What are the most common symptoms of vitamin D deficiency?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The most common signs of vitamin D deficiency vary by age. Children may complain of pain in their bones and muscles and exhibit signs of weakness, joint deformities, and bowed or bent bones (medically known as rickets). <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK532266\/#:~:text=In%20children%2C%20symptoms%20of%20vitamin%20D%20deficiency%20can%20include%20irritability%2C%20lethargy%2C%20developmental%20delay%2C%20bone%20changes%2C%20and%20fractures.\"><span style=\"font-weight: 400;\">Irritability and developmental delays<\/span><\/a><span style=\"font-weight: 400;\"> can also occur.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most adults with vitamin D deficiency notice no signs or symptoms. Those who do experience symptoms commonly report bone pain, fatigue, and muscle weakness, pain, or twitching.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cIt\u2019s incredibly easy to mistake vitamin D deficiency for other medical conditions because its primary symptoms match signs of fibromyalgia, chronic fatigue syndrome, or clinical depression,\u201d says <\/span><a href=\"https:\/\/www.paramountwellnesscenters.org\/contributors\/\"><span style=\"font-weight: 400;\">Gail Clifford<\/span><\/a><span style=\"font-weight: 400;\">, MD, an internal medicine hospitalist based in Connecticut.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cMany patients are told their exhaustion is just part of being busy or aging, when in reality their vitamin D serum levels are critically low. Additionally, vitamin D\u2019s absence can cause mood swings and brain fog that looks identical to perimenopause or a thyroid imbalance.\u201d\u00a0<\/span><\/p>\n<h2 id=\"weird-symptoms-of-vitamin-d-deficiency\"><span style=\"font-weight: 400;\">Weird symptoms of vitamin D deficiency<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A vitamin D deficiency can cause wide-ranging and unexpected symptoms that some may consider to be \u201cweird.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cSome patients experience burning mouth syndrome or a metallic taste,\u201d Dr. Clifford says. \u201cOthers report chronic bone tenderness, where it hurts to press on their shins or breastbone.

Chester<\/span><\/a><span style=\"font-weight: 400;\">, MD, a doctor of osteopathic medicine based in Kailua Kona, Hawaii, says he\u2019s seen vitamin D deficiencies change people\u2019s behavior. \u201cFor example, a person who has generally always been pretty disciplined and organized might start procrastinating. This is actually due to the way vitamin D can influence insulin, dopamine, and serotonin levels, which are tied to things like motivation and focus.\u201d\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Dr. Chester adds that it can be easy to confuse symptoms of low vitamin D for things like depression, ADHD, anxiety disorder, chronic fatigue syndrome, and neuropathy.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Other weird symptoms of a vitamin D deficiency include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Frequently getting sick<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Infections that take a long time to heal<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Night sweats<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Severe vitamin D deficiency can lead to secondary hyperparathyroidism, a condition characterized by excessive secretion of parathyroid hormone.

Also known as hypocalcemia, this condition causes a range of symptoms depending on how low your blood calcium levels get. A mild case of hypocalcemia can contribute to muscle cramping, particularly in the legs and back. <\/span><a href=\"https:\/\/my.clevelandclinic.org\/health\/diseases\/23143-hypocalcemia\"><span style=\"font-weight: 400;\">Other symptoms<\/span><\/a><span style=\"font-weight: 400;\"> of mild hypocalcemia may include the following:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Dry, scaly, or itchy skin<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Brittle nails<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Coarse hair growth<\/span><\/li>\n<\/ul>\n<h2 id=\"severe-or-long-term-symptoms-of-vitamin-d-deficiency\"><span style=\"font-weight: 400;\">Severe or long-term symptoms of vitamin D deficiency<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">If common or weird symptoms of vitamin D deficiency aren\u2019t addressed early, they can become severe or long-term.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, if hypocalcemia is left untreated, you may begin to experience more psychological symptoms, like depression, irritability, memory problems, confusion, or hallucinations. Critically low blood calcium levels can cause seizures, an irregular heartbeat, tingling in your feet, fingers, tongue, or lips, difficulty breathing, stiff muscles, or congestive heart failure.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Long-term or severe vitamin D deficiency also increases the risk of bone conditions like <\/span><a href=\"https:\/\/www.singlecare.com\/conditions\/osteoporosis-treatment-and-medications\"><span style=\"font-weight: 400;\">osteoporosis<\/span><\/a><span style=\"font-weight: 400;\"> and osteomalacia. Osteoporosis occurs when the bones lose some of their density, causing them to become thinner and more fragile.

However, other risk factors can make it tougher for the body to use vitamin D.<\/span><\/p>\n<h3 id=\"diet\"><span style=\"font-weight: 400;\">Diet<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Certain mushrooms and a few animal-based foods, including fatty fish, beef liver, egg yolks, and cheese, <\/span><a href=\"https:\/\/ods.od.nih.gov\/factsheets\/VitaminD-HealthProfessional\/#h4\"><span style=\"font-weight: 400;\">contain vitamin D<\/span><\/a><span style=\"font-weight: 400;\">. It\u2019s also added to some foods, like breakfast cereals, orange juice, and milk, to help people get enough in their diet. Those who don\u2019t eat enough natural or fortified sources of vitamin D may be at an increased risk of vitamin D deficiency.\u00a0<\/span><\/p>\n<h3 id=\"sun-exposure\"><span style=\"font-weight: 400;\">Sun exposure<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">People may not get enough sunlight for a variety of reasons, like working the night shift or staying indoors due to health problems. But you may not get enough vitamin D even if you spend plenty of time outside.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Vitamin D production is also affected by how far you are from the equator, the time of year, cloudy days, and how much skin is actually exposed to the sun.\u00a0<\/span><\/p>\n<h3 id=\"skin-tone\"><span style=\"font-weight: 400;\">Skin tone<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Having a darker skin tone means your body may not efficiently create vitamin D in response to sunlight. Skin pigment called melanin acts as a natural sunblock. People with high amounts of melanin need a lot more sun exposure for adequate vitamin D synthesis compared to people with low amounts of melanin.\u00a0<\/span><\/p>\n<h3 id=\"health-conditions-and-medications\"><span style=\"font-weight: 400;\">Health conditions and medications<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Sometimes a vitamin D deficiency develops because of medical conditions that change the way the body absorbs or produces vitamin D. This may happen due to digestive disorders, kidney disease, or obesity. Certain medications can also increase your risk of vitamin D deficiency.\u00a0<\/span><\/p>\n<h3 id=\"age\"><span style=\"font-weight: 400;\">Age<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">People aged 65 and older are more likely to become deficient in vitamin D. Over time, the skin naturally loses some of its ability to synthesize this nutrient. Babies exclusively fed breast milk are also at greater risk of vitamin D deficiency.\u00a0<\/span><\/p>\n<p><b>RELATED: <\/b><a href=\"https:\/\/www.singlecare.com\/blog\/vitamin-d-prescription\/\"><b>Why would I need a vitamin D prescription?<\/b><\/a><\/p>\n<h2 id=\"how-to-prevent-and-treat-vitamin-d-deficiency\"><span style=\"font-weight: 400;\">How to prevent and treat vitamin D deficiency?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Exposing your skin to safe levels of sunlight and eating foods rich in vitamin D may be enough to prevent a deficiency. However, your healthcare provider may recommend taking vitamin D supplements if you\u2019re already deficient or are at an increased risk of deficiency.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are two main types of vitamin D: D2 and D3. Vitamin D2 is <\/span><a href=\"https:\/\/ucfhealth.com\/our-services\/lifestyle-medicine\/what-is-the-difference-between-vitamin-d2-and-vitamin-d3\/\"><span style=\"font-weight: 400;\">usually found<\/span><\/a><span style=\"font-weight: 400;\"> in fortified foods. However, it is not as well absorbed in the body as <a href=\"https:\/\/www.singlecare.com\/prescription\/vitamin-d3\/what-is\">vitamin D3<\/a>. Your body creates vitamin D3 in response to sunlight, and you can increase your D3 levels by eating certain animal-based foods. Researchers have found that vitamin D3 supplements may be more effective at treating vitamin D deficiencies.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You can buy low doses of both types in over-the-counter vitamin D supplements. There are also high-dose vitamin D supplements available with a prescription for people with severely low vitamin D levels. Talk to a healthcare provider before starting a vitamin D supplement to make sure it won\u2019t interact with other medications or cause elevated vitamin D.\u00a0<\/span><\/p>\n\t\t<div id=\"coupon-cta\" class=\"coupon-cta master-template\">\n\t\t\t<p id=\"headline\">Save up to 80% on Vitamin D3 with SingleCare<\/p>\n\t\t\t<p id=\"subheadline\">Different pharmacies offer different prices for the same medication.

To make sure a vitamin D deficiency doesn\u2019t go untreated for too long, ask your healthcare provider how often you should get your levels checked. Vitamin D deficiency is diagnosed through a simple blood test that\u2019s often run at annual check-ups. Find out if you\u2019re regularly getting tested, and ask for a vitamin D test if not. If your test is done in the summer, consider getting tested again in the winter when there\u2019s less sun exposure.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you always feel tired no matter how much you sleep, notice persistent mood issues like depression or anxiety, or have unexplained bone and muscle pain, don\u2019t wait for your annual checkup. Talk to a healthcare provider right away about a vitamin D test. A simple supplement may be all it takes to improve your quality of life.\u00a0\u00a0<\/span><\/p>\n<h2 id=\"can-you-take-too-much-vitamin-d\"><span style=\"font-weight: 400;\">Can you take too much vitamin D?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Although vitamin D supplements are available over the counter (OTC), you should talk to a healthcare provider before starting them. <\/span><a href=\"https:\/\/www.singlecare.com\/blog\/too-much-vitamin-d\/\"><span style=\"font-weight: 400;\">Too much vitamin D<\/span><\/a><span style=\"font-weight: 400;\"> can cause some of the same symptoms of vitamin D deficiency, like muscle pain and mood disorders, plus some additional symptoms like kidney stones. Typically, your healthcare provider will run a blood test to see if you need any supplements at all. Then, they\u2019ll run regular follow-up tests to make sure your levels improve but don\u2019t get too high.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some people need a much greater dose of vitamin D than what\u2019s available in over-the-counter supplements. <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/vitamin-d-high-potency\"><span style=\"font-weight: 400;\">High-potency vitamin D<\/span><\/a><span style=\"font-weight: 400;\"> is only available with a prescription.
