Caffeine: How Many Servings Can Trigger a Migraine?

Most of us like a good cup of joe in the morning (or throughout the day) — but for people who suffer from migraines, there’s usually a limit on how much of the caffeinated beverage can be consumed.

But how much caffeine is too much before a migraine is triggered?

Harvard researchers recently set out to find the answer. In a small study published in The American Journal of Medicine, the researchers studied 100 adults who suffer from frequent headaches. They were asked to record their daily intake of caffeinated drinks — like coffee, tea, soda, energy drinks and alcohol. The patients also recorded their headache episodes.

Here’s what researchers discovered after evaluating the data:

Having three or more servings of caffeinated drinks in a day was associated with higher odds of having a migraine on that day or the following day. Meantime, having one to two servings of caffeinated beverages was not associated with migraines.

Does that mean people prone to migraines can safely enjoy up to two caffeinated drinks per day? Not quite. The study is only observational and doesn’t prove that any amount of caffeine will or won’t cause migraines. But if you are prone to migraines, watch your headache triggers, and perhaps keep a journal of daily activity (including caffeine intake) to help discover your trigger limits.
