About Magnesium Chloride Flakes

These are the most common uses for Magnesium Chloride Flakes. Each card explains what to do, why it works, and what to notice.

How to use Magnesium Chloride Flakes for bath soaks

Add 1–2 cups to a warm bath and soak for 20 minutes.

Why it works for bath soaks

A mineral-rich soak relaxes tired muscles, eases tension, and pulls a bit of magnesium into the skin (with Epsom salt specifically). The warmth + the salt is one of the oldest "self-care" rituals in the book.

What you'll notice
  • Ease sore muscles after a workout
  • Soften skin
  • Wind down before bed
  • Pair with lavender for sleep
  • A 20-minute mental reset

How to use Magnesium Chloride Flakes for throat gargle

Dissolve 1/2 teaspoon in 8 oz of warm water. Gargle and spit, repeat several times.

Why it works for throat gargle

Salt water is the oldest sore-throat remedy in the world. The salt draws fluid out of irritated tissue, reducing swelling, and creates a hostile environment for the bacteria that linger after a cold.

What you'll notice
  • Soothe a sore throat in minutes
  • Reduce throat swelling
  • A free, low-tech remedy
  • Pair with hot tea + honey
  • Safe for daily use

How to use Magnesium Chloride Flakes for body scrubs

Mix 1 cup of salt with 1/2 cup of carrier oil. Massage onto damp skin in the shower; rinse.

Why it works for body scrubs

A body scrub lifts off dead skin cells, smooths rough patches, and leaves your skin softer than any lotion can. The oil base lets you skip moisturizer afterward.

What you'll notice
  • Smooth elbows, knees, heels
  • Polish skin to softness
  • Skip the lotion step after
  • Pair with essential oils for mood
  • Better than store-bought scrubs

How to use Magnesium Chloride Flakes for natural household cleaning

Sprinkle on sinks, tubs, or stovetops, scrub with a damp cloth, rinse clean.

Why it works for natural household cleaning

Baking soda and salt are mild abrasives that lift grime without scratching most surfaces. They're effective, food-safe, and dirt cheap — the foundation of non-toxic cleaning.

What you'll notice
  • Cut grime without harsh chemicals
  • Food-safe in kitchens
  • Replace expensive abrasive cleaners
  • Pair with vinegar or lemon
  • Won't scratch most surfaces

How to use Magnesium Chloride Flakes for electrolyte rehydration

Stir a pinch of good salt into a glass of water with a squeeze of lemon and a teaspoon of honey.

Why it works for electrolyte rehydration

When you're dehydrated, plain water isn't enough — your body needs the minerals (sodium, potassium) that water alone doesn't deliver. A homemade electrolyte drink is a clean alternative to store-bought ones full of dyes and sugar.

What you'll notice
  • Rehydrate after a hot day or workout
  • Skip the artificial sports drinks
  • Pair with coconut water for extra potassium
  • A pinch of salt makes a big difference
  • Cheap and clean
