Does Re-Lyte Hydration expire?

Re-Lyte Hydration doesn't expire.

Re-Lyte Hydration contains shelf-stable ingredients that stay safe indefinitely, so it never expires. It also includes a generous dose of our unrefined sea salt Real Salt, which acts as a natural preservative. 

If you live in a humid area, you may notice that the Re-Lyte in your jar starts to flow less freely or clump together over time. This happens because two ingredients in Re-Lyte, salt and citric acid, both attract water (and we don't add any chemical anti-caking agents to prevent this from happening). But even when this happens, your Re-Lyte is still perfectly safe to use.
