Our Research

Built on studied ingredients, not empty energy claims.

Caffeine Crashers was created to empower consumers to choose how much energy they actually need, rather than having a high dose decided for them.

Our product is built around ingredients that have been researched for their role in energy, attention, focus, and cognitive performance.

Our formula combines a unique ratio of naturally sourced caffeine with L-Theanine to support a cleaner, more controlled energy experience. Caffeine helps increase alertness and reduce tiredness, while L-theanine is commonly studied for its calming, focus-supporting effect.

Together, this combination is designed to support energy, focus, and performance without the aggressive spike-and-crash feeling people often associate with traditional caffeine products.*
