Yes, vitamin D significantly affects brain fog, as deficiency is linked to cognitive issues like poor concentration, memory problems, and fatigue, while adequate levels support brain function, with receptors found throughout the brain. Many people experiencing brain fog, characterized by mental confusion and difficulty focusing, might find relief through vitamin D supplementation, especially if they are deficient, as it supports neurotransmitter production and reduces inflammation.
“If you take too much, vitamin D toxicity can cause brain fog, as well as aches and pains. Vitamin D also does not wash out of your system quickly. So, if you take too much, you're just stuck waiting for it to come out, which can be weeks.”
Does vitamin D interact with other medications? Yes. Steroid medications such as prednisone can interfere with vitamin D metabolism. If you take steroid drugs regularly, discuss vitamin D with your doctor.
When vitamin D deficiency is identified during pregnancy, most experts agree that 1,000–2,000 international units per day of vitamin D is safe. Higher dose regimens used for the treatment of vitamin D deficiency have not been studied during pregnancy.
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 ...
The Bottom Line
Vitamin D vs D3, what's the difference? Technically, vitamin D relates to both vitamin D2 (which comes from plants) and vitamin D3 (which the body produces naturally and also comes from animal foods). However, both forms function similarly in the body.
Vitamin D supplements can interact with other medications. Examples of vitamin D interactions include atorvastatin (Lipitor), cholestyramine (Prevalite) and phenytoin (Dilantin, Phenytek). Other Vitamin D drug interactions include orlistat (Xenical, Alli), digoxin (Lanoxin), and hydrochlorothiazide (Microzide).
You don't absorb enough vitamin D from food (a malabsorption problem) You don't get enough exposure to sunlight. Your liver or kidneys cannot convert vitamin D to its active form in the body. You take medicines that interfere with your body's ability to convert or absorb vitamin D.
have problems with your kidneys, such as kidney failure, or you've ever had kidney stones. have hypervitaminosis D – high levels of vitamin D in your blood. have a rare condition called sarcoidosis. have calcification – high levels of calcium in your body tissues or organs.
Care and Treatment

Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.

Medical conditions that can cause vitamin D deficiency include: Cystic fibrosis, Crohn's disease and celiac disease: These conditions can prevent your intestines from adequately absorbing enough vitamin D through supplements, especially if the condition is untreated.
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.
Vitamin D deficiency primarily causes bone diseases like Rickets in children (soft, bent bones) and Osteomalacia (soft bones) in adults, leading to pain and weakness, plus increased risk for Osteoporosis and fractures. Long-term deficiency is also linked to muscle weakness, increased falls, cardiovascular issues, diabetes, and autoimmune disorders, though these connections are complex.
Vitamin D absorption can be prevented by limited sun exposure (dark skin, sunscreen, covering up, indoor lifestyle), medical conditions (celiac, Crohn's, cystic fibrosis, liver/kidney disease, obesity), certain medications (steroids, anti-seizure drugs, weight-loss drugs), and even some nutritional factors like low magnesium, with fat malabsorption issues and obesity being major culprits for preventing both dietary and sun-derived vitamin D from working effectively.
About 50% of people worldwide have low vitamin D levels. And between 10% and 30% of the population are thought to have low levels of magnesium. For many people, it's important to take vitamin D and magnesium together. Without magnesium, your body can't use vitamin D.
The two most common mistakes when taking vitamin D are taking it without adequate fatty foods for absorption, and neglecting to take it with Vitamin K2 and magnesium, which are crucial for directing calcium to bones and activating the vitamin D in your body, respectively, leading to ineffective supplementation or calcium buildup issues. Many also mistakenly choose the less effective D2 form over D3, or take incorrect dosages without blood tests, according to this snippet from Healthshots, this snippet from GrassrootsHealth, this snippet from Yahoo! Health, this snippet from the Cleveland Clinic Journal of Medicine, and this snippet from Verywell Mind.
Green peas (Matar): Green peas, also known as matar, serve as a beneficial source of vitamin D. Including green peas in your meals can provide you with this essential nutrient.
