Extremely effective against aural migraines.

Posted by 4762521851597898409 on Dec 19, 2016

I had been experiencing aural migraines almost every other day and they were lasting up to 45 minutes. They were limiting my ability to drive due to a concern that I would lose my vision while driving. I did not want to begin taking yet another prescription medication, so I asked my doctor if I might try a natural solution. She suggested that I try 400 mg per day of Riboflavin; the aural migraines were completely gone after only two weeks. I couldn't be happier with the results.

Bought this for migraines

Posted by 5017968226559265396 on Dec 04, 2016

I regularly take medication for migraines and have a couple back-up medications for any break-through migraines. Lately, the break-through migraines have been becoming more frequent so I looked up some ways to help. A study showed that 400mg of B2 a day has been shown to help. My break-through migraines still occur, but are less frequent (down from several times a week to once or twice a week). I am also taking 400mg of magnesium for the same reason.

great product, packaging is criminal

Posted by Reviewer2169605 on Oct 04, 2015

It's brillinat to get the level of riboflavin recommended for migraine prevention in one to two pills versus the other brands, however, in a world where we are literally choking onplastic waste, the bottle is ridiculous. You see the photo? Well, the contents only fills to the orange stripe on the label where there or the words 'energy production' are. I am NOT kidding. The companies that do this should be required to package more responsibly. Not only is it grossly irresponsible, but extremely inconvenient for the customer.
