Support muscle relaxation and recovery with traditional Epsom salt magnesium

Each capsule provides 104mg of elemental magnesium from magnesium sulfate. This is the same compound commonly known as Epsom salt, traditionally used in baths for muscle relaxation and recovery. In oral capsule form, it provides both magnesium and sulfate. The sulfate component is relevant because sulfation is a critical phase II liver detoxification pathway, and some individuals with impaired sulfation may benefit from supplemental sulfate.

Magnesium sulfate is well absorbed orally and has a moderate osmotic effect, meaning it draws some water into the bowel. This makes it useful for those who experience mild constipation alongside magnesium deficiency. The osmotic effect is milder than magnesium citrate at equivalent doses. At 104mg elemental magnesium per capsule (28% NRV), a single capsule provides a meaningful maintenance dose. The vegetarian capsule shell is hydroxypropyl methylcellulose.

Key benefits:

  • Muscle relief and recovery support
  • Detox support through sulfate pathways
  • Proven Epsom salt for effectiveness
Each capsule contains: %NRV*
Magnesium 104 mg 28%

† Nutrient Reference Value (NRV*) not established

Magnesium Sulfate, Hydroxypropyl Methylcellulose (capsule).

Directions for use:

Take 1 capsule per day with food.

Taking with a meal supports absorption and reduces any chance of digestive sensitivity. If using specifically for sulfation support (relevant for those with chemical sensitivities, impaired detoxification or histamine issues), this product provides a convenient oral source of bioavailable sulfate without requiring Epsom salt baths.

For those needing magnesium primarily for sleep or relaxation without the osmotic bowel effect, Magnesium Bisglycinate is the better targeted choice. Magnesium Sulfate is most appropriate when the sulfate component is specifically desired or when mild bowel support is welcome alongside magnesium replenishment.

Magnesium: glycinate vs citrate vs malate vs threonate?

Magnesium comes in several different chemical forms when sold as a supplement, and they are not interchangeable. They absorb at different rates and have different evidence bases for specific uses. Glycinate is well tolerated and absorbed via a different gut pathway than oxide, making it the typical default for general supplementation, sleep, and anxiety. Citrate is well absorbed but has a more pronounced laxative effect at higher doses. Malate fits energy metabolism contexts. L threonate is brain penetrant for cognitive applications. A 2022 systematic review in the journal Nutrition confirms that direct head to head trials comparing forms for specific clinical outcomes remain limited.
