Our patented rice-based formula makes Cera the worldwide choice to safely and effectively rehydrate and keep you hydrated.


We Started With Saving Lives

Cera founder, Charlene Riikonen began her journey in Bangladesh, saving lives from severe dehydration caused by infectious diarrhea using Oral Hydration Solutions (ORS). After returning to the US, Riikonen started Cera products, Inc. in 1993, determined to create a more effective ORS that uses a natural complex carbohydrate source instead of simple sugars. After years of developing and perfecting the product line, she patented the revolutionary rice-based rehydration formula. Today, millions of people across the world use Cera for their hydration needs.

Benefits of Cera

Rice is a Complex Carbohydrate

Glucose is necessary to absorb sodium when the body is stressed from dehydration or exercise. Unlike most sports drinks that use simple sugars and fructose, our rice formula is made of glucose polymers from complex carbohydrates.

More Sodium Is Absorbed

Simple sugars are only absorbed in the top portions of the small intestine. Rice is absorbed throughout the entire small intestine, resulting in more sodium and fluid is obtained and retained by your body. This is why Cera works better than IV fluids.

Electrolytes Travel Faster

Complex carbohydrates deliver a lower osmolality solution than sugary products, so fluids leave your stomach quickly and are absorbed faster into the bloodstream.

You Stay Hydrated

Your body absorbs and retains more fluids and electrolytes for sustained hydration.
