A headache is pain you feel in the head, neck and scalp that ranges from mild to severe, and it is rarely caused by anything serious, according to MedlinePlus. You can usually manage headaches with lifestyle changes and medications. You may be able to prevent one type of severe headache, the migraine headache, by taking riboflavin supplements.
Migraine Headache Symptoms
You may go through four stages with migraine headaches, according to MayoClinic.com. The prodrome may last one or two days and may include constipation, depression, diarrhea, cravings, hyperactivity, irritability and neck stiffness. The second stage is the aura that may cause visual, motor and sensory problems. The third stage is the attack stage when you experience throbbing head pain, light sensitivity, nausea, blurry vision and lightheadedness. The final stage is the postdrome, which is a time when you may feel drained and worn out.
Migraine Causes
The University of Maryland Medical Center says researchers aren't sure what causes migraines, but blood flow in your brain is altered. Your blood vessels constrict and blood flow decreases, which may lead to symptoms in the first two stages of your migraine. When your blood vessels dilate, increased blood flow leads to the severe pain of the attack stage. Certain foods, beverages, noises, bright lights, stress, heat, smoke, perfume, heat and humidity can all trigger migraines.
Riboflavin
Vitamin B-2, or riboflavin, is a member of the B complex family of vitamins. It's found in milk, meat, eggs, nuts, vegetables and enriched foods. According to MedlinePlus, riboflavin supplements treat riboflavin deficiency, acne, cramps, burning feet syndrome, carpal tunnel syndrome and blood disorders. Riboflavin supplements also prevent migraine headaches, according to MedlinePlus.
Riboflavin for Migraine Prevention
The University of Maryland Medical Center says a few research studies show riboflavin may reduce the frequency and severity of migraine headaches when taken at 400 mg per day. MedlinePlus says 400 mg riboflavin reduces the number of attacks but not the amount of migraine pain or length of time you have the migraine. Always speak to your doctor before you take any dietary supplements in large doses, including riboflavin.
