What is the main difference between Tart Cherry and Spirulina Blue Lemonade Magic Magnesium?

We created Tart Cherry Magic Magnesium for those nights when you need extra help easing into rest. Unlike our original Spirulina Blue Lemonade, it includes a microdose of plant-based melatonin (0.5 mg) to support a smoother transition to sleep, without the grogginess.* Tart Cherry Magic Magnesium is also formulated with magnesium glycinate instead of the magnesium citrate used in the original, offering a gentler form that’s easy on the stomach and deeply calming.
