Why should we use magnesium chloride?

In short, many people's bodies are deficient in magnesium. Maintaining adequate magnesium levels needs to be a daily habit. Magnesium chloride can be used in a few different forms, all of which promote health, wellness, relaxation and muscle recovery. It is often thought of as one of the best ways of replenishing the body’s cellular magnesium levels, particularly after intensive exercise. All you need to do is bathe in it, spray it onto your skin or massage it into sore spots.

If using magnesium flakes, we suggest dissolving 2-3 cups of it in a warm bath, and soaking in it for 20-30 minutes. If using a spray instead, you can spritz yourself with around four sprays every day. You can even use magnesium flakes to level up your foot bath, instantly decompressing your feet and easing the day’s tension.

From arthritis sufferers to elite athletes, magnesium chloride can offer great relief and relaxation. Try it as part of your next bath or self-care session.
