Hydration Trends Are Moving Beyond Electrolytes Into Glycerol, Algae, and Amino Acids

Product launches in the hydration category grew 54% between 2021 and 2025. Majority brands are moving beyond electrolyte counts. The next edge in this category is coming from absorption science.

Five mechanisms driving this shift: Glycerol-based hydration, fast/rapid hydration, algae-based hydration, amino acid co-transport, and low-GI hydration. Each sits at a different stage of development and is held by a different set of companies.

PepsiCo is running clinical trials on glycerol-based hydration. Coca-Cola has filed a patent on rapid plasma fluid uptake. And Abbott is betting on a marine-algae hydration ingredient. 

This report maps where each of the five emerging mechanisms in the hydration category stands today. It maps which companies are moving fastest, what their patents signal, and where the white space sits. 

What’s Inside the Report
