Calm Zone magnesium powder appears in different package sizes, including an eight-ounce, 50-serving example at Calm Zone Magnesium Powder – 325 MG – Raspberry Lemon Relaxation Drink (8 oz./50 Servings). Raspberry Lemon is the flavor described in the listings. Compare the 50-serving and 100-serving packages using their actual labels and current prices. Relaxation language is product positioning; it does not determine the right amount for you or establish that every magnesium powder has the same composition.
