Magnesium Flake Dosage: How Much Should You Add to Your Bath?

How Much Magnesium Should You Add to a Bath?

If you’re new to magnesium soaks, it’s important to get the dosage right. Adding too little might not deliver the benefits you’re looking for—too much can irritate sensitive skin. Let’s break down the ideal amount for a relaxing and effective bath.

According to Sea Magik, a trusted authority in bath mineral therapy:

“We recommend adding up to 4 handfuls into warm water… soaking for at least 20 minutes.”

This translates to approximately 1 to 3 cups (about 100–300g) for most standard tubs. For deeper tubs or more intense recovery needs, you can increase to 4 cups—but always listen to your body and avoid overdoing it.

Safety Tips for Soaking

• Always dissolve flakes completely in warm—not hot—water.

• Avoid using more than 4 cups unless directed by a health professional.

• If you have sensitive skin, start with a smaller amount (1 cup) to assess tolerance.

• Stay hydrated before and after your soak.
