Magnesium Orange by Garden of Life

If you’re searching for magnesium powder for sleep, tense muscles, or nighttime leg cramps, this fits. It’s a practical daily dose if your Serum Magnesium or Magnesium, RBC is in the lower range, you train hard and sweat often, or you’re on medicines that waste magnesium like some diuretics or long-term acid reducers. The 350 mg here is a solid maintenance dose; if you have a clear deficiency on labs or ongoing constipation issues, clinicians often use higher total daily magnesium, then step down.

Magnesium helps muscles relax by balancing calcium flow into muscle cells, and it sits at the center of ATP, the molecule your cells use for energy. A water-dissolving “fizz” (magnesium combined with citric acid to form a soluble salt) generally absorbs better than oxide, and the chelate bound to rice protein is typically gentler on the gut. Together they can ease cramps within days and improve sleep quality through calming GABA receptor activity (your brain’s main “brake” signal). The 120 mg sodium adds an electrolyte nudge for hydration during or after workouts.

Stir one scoop into room‑temperature water, let it finish fizzing, then drink. Evening is preferred if sleep or nighttime cramps are the goal; morning or post‑training also works for athletes. Take with or without food. If you’re sensitive or get loose stools, split the scoop into two smaller servings 6 to 8 hours apart. Expect muscle and sleep effects within 1 to 2 weeks, sometimes sooner for cramp frequency.

Space magnesium powder at least 2 hours from levothyroxine, and 2 to 4 hours from tetracycline or fluoroquinolone antibiotics, because minerals can block absorption. Do the same with bisphosphonates for bone. If you have significant kidney disease, uncontrolled heart block, or you’re on magnesium-containing laxatives already, use only with clinician guidance. Persistent diarrhea, new weakness, or very low blood pressure after starting warrants stopping and checking labs.
