Why this happens
Magnesium and vitamin B2 do not interfere with each other's absorption or metabolism. Instead, they have a 'synergistic' effect, meaning they help each other work. For example, magnesium is required for the body to properly use certain vitamins, and both are involved in the same energy-production processes within your cells.
What you should do
It is safe to take these two supplements together. They are frequently combined in a single tablet, particularly for people trying to prevent migraines. As with any supplement, stick to the recommended daily dose on the packaging unless your doctor tells you otherwise.
