What's the difference between Re-Lyte Hydration Support and Muscle Support capsules?

They're the same Real Salt-based formula with a different name.

Re-Lyte Hydration Support and Re-Lyte Muscle Support capsules both contain one ingredient— Real Salt. The only difference between the two? The name. We named one version for customers who want hydration support and one for customers who want muscle support since Real Salt provides both.
