ALPHA LION Burn2O is a liquid fat-burning supplement designed to support metabolism, with 2000 mg of L-carnitine plus MitoBurn® and CaloriBurn GP®.
Burn2O is made for people looking to add liquid fat-burning support to their day, whether around a workout or as part of a daily routine. Its formula is designed to support fat loss without requiring intense workouts, making it an option for busy schedules as well as training days.
The formula is designed to support thermogenesis by engaging brown adipose tissue (BAT), the mechanism associated with its calorie-burning approach.

The formula is also designed to support sustained energy and workout performance, while its fat-loss support does not depend on intense workouts.
Burn2O is vegan-friendly, gluten-free, calorie-free, and sugar-free, and it is presented as suitable for keto and fasting routines. Its liquid format gives shoppers an alternative to a capsule-based supplement. Other listed flavor options include ShredBerry and ScorchBerry.
