Big effect
A 12-week trial found women with migraine who took 500 mg/day of L-carnitine plus ALA reported nearly 3 fewer migraine attacks — while the placebo group saw essentially no change
This is an unusually large and clean effect from a well-designed trial, but it's the first study to test this specific combination, so the result needs replication before anyone should bet their migraine management on it.
Eighty women with migraine were randomly assigned to take either a daily combination of L-carnitine (500 mg) and alpha-linolenic acid (ALA) or a placebo for 12 weeks. By the end, the supplement group had about three fewer migraine attacks per month on average, while the placebo group's frequency barely budged, and the difference was statistically very reliable.
Where this fits in the evidence
This is among the first studies we've indexed on L-Carnitine for Reduced Migraine Frequency — treat it as an early signal until more research accumulates.
