GUAI-AID™ works better than Mucinex and saves me a fortune every month

Over the years, I’ve tried many different brands of guaifenesin for mucus relief.

Guai-Aid™ 600mg Capsules are smaller than other brands and easier to swallow, all while being less expensive and containing less binder than other brands.

Best on Amazon hands down!
