Before you choose.
Does zero sugar mean the same formula?
No. 310 and LMNT both list zero sugar, but their sodium and potassium amounts differ. Liquid I.V. and DripDrop also have separate zero-sugar lines that are not the original formulas compared here.
How do you choose your picks?
We compare published labels, ingredients and prices, and highlight the best fit for each need. Our labels are editorial recommendations, not numeric scores. 310 Hydrate is our top pick for everyday buyers who want zero sugar.
How are prices shown?
Each price is the one-time price of the exact pack, read from the brand’s own product page; the price per serving is that price divided by the servings in the pack. We checked them on October 18, 2026. Subscriptions, bundles and introductory deals can differ, so check the brand’s current offer before buying.
Is more sodium always better?
No single sodium amount is right for everyone. If you have a sodium restriction or a medical condition affecting fluid balance, follow your clinician’s advice and the product label.
