How to use

How to use

Add 2 cups of flakes to a warm bath, or 1 cup for a foot soak.

Use warm water rather than hot. Warm water helps the magnesium absorb, while hot water can dry out your skin. Soak for at least 20 minutes to relieve sore muscles and achy joints.

Follow with Melt Pain Away for enhanced muscle and joint relief. Or use Treat Your Feet after a foot soak with these flakes for enhanced skin softening and relief.

When to use

Soak after a workout, pickleball match or long walk to ease sore muscles
Use after gardening or yardwork like shoveling the driveway
Add to a bedtime bath to help you, the kids or the grandkids wind down for sleep
Soak feet after a long day on your feet
Give as a thoughtful gift for mom, sister or anyone who could use a relaxing ritual

Magnesium Chloride Flakes

"Bought this for my son for Christmas 🎄"

— Sandra L. (5/5)

The most relaxing and relieving!

"Our whole family loves these bath flakes! We literally fight over them and buy them on repeat (I highly recommend a monthly subscription). They help you relax before bed and relieve areas of tension of soreness. My son is a very active sports kiddo and he will take a shower post practice/game and then run a magnesium bath. The magnesium helps so much with muscle tension and tightness and overall relaxation."
