can too much vitamin d cause headaches?

No: Vitamin D toxicity is very rare; one generally has to take at least 40,000 iu/day for months to get toxic levels. Symptoms of toxicity include poor appetite, excess thirst, frequent urination, constipation or diarrhea, abdominal pain, fatigue, confusion, muscle weakness or pain, irritability, nausea and vomiting but headache is not a know symptom.

Yes: too much vitamin D can cause headaches. The term is called pseudotumor cerebri and it can occur from too much vitamin A, D, Tetracycline. Stopping the vitamin D should reverse the headaches.
Dr. Bennett Machanic
Neurology 52 years experience
Cannot agree, as there is currently no known link with Vitamin D and Pseudotumor Cerebri, and not clear that Vitamin D causes headache issues either. The question of "too much vitamin D" is not fully clear either, but levels of 50-70 ng/ml seems reasonable goal.

A 45-year-old member asked:

What foods have vitamin d?

Few natural sources: Fatty fishes (tuna, mackerel, catfish, salmon) are one source. Eggs have some; beef liver has a little. Cod liver oil has a lot. Many dairy products and some cereals are fortified with vitamin d, meaning that vitamin d has been added to them. Of course you can also take a vitamin d supplement or multi-vitamin. Sunlight causes your skin to produce vitamin d, so some call it the sunshine vitamin.

Good question: Vit d is under increasing study. I am impressed with how many pts, are deficient. Your doc can do a simple blood test and also monitor if your replacement tx is enough. We know it helps bone regeneration, it is necessary for some meds to work. Eat healthy, and see if you need more supplements if you are losing height or have family hx of osteoporosis.
A 45-year-old member asked:

Is vitamin d a type of macronutrient?

3 doctor answers6 doctors weighed in
Dr. Bryan Levey
Pediatrics 27 years experience
No: Macronutrients are carbohydrates (sugars and starches), lipids (fats) and proteins. Vitamin d is none of these; it's a compound found in a few foods, but mostly made in your skin when you are exposed to sufficient sunlight. Your body uses vitamin d in many ways. Macronutrient use by your body is somewhat simpler. Carbs are for fuel. Fats are for energy storage. Proteins are building blocks.

Can you please guide me on foods with a high vitamin d level?

Dr. Maritza Baez
Family Medicine 17 years experience
Fortified foods: The flesh of fatty fish (such as salmon, tuna, and mackerel) and fish liver oils are among the best sources. Small amounts of vitamin d are found in beef liver, cheese, and egg yolks. Some mushrooms provide vitamin d2 in variable amounts. Ready-to-eat breakfast cereals often contain added vitamin d, as do some brands of orange juice, yogurt, margarine and other food products.
