Varför detta händer

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.

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.

Kidney disease

If you have severe kidney problems, your body may not be able to remove excess magnesium, leading to dangerously high levels in the blood. Check with your doctor before use.

Alkohol

It is best to avoid or strictly limit alcohol when taking magnesium. Alcohol acts as a diuretic, which can increase the amount of magnesium your body loses through urine, potentially making the supplement less effective. Additionally, chronic alcohol use can lead to magnesium deficiency.

It is best to avoid or strictly limit alcohol when taking Vitamin B2. Alcohol can interfere with the way your body absorbs this vitamin from the digestive tract, making the supplement less effective.

Dairy products (Milk, Cheese, Yoghurt)

Avoid taking magnesium supplements at the same time as large amounts of dairy products. Dairy is high in calcium, and high doses of calcium can compete with magnesium for absorption in the gut, meaning you may not get the full benefit of your supplement. It is best to space them at least 2 hours apart.

Caffeine (Coffee, Tea, Energy drinks)

It is best to limit caffeine intake around the time you take magnesium. Like alcohol, caffeine has a mild diuretic effect and can increase the excretion of magnesium through the kidneys.
