Used in dietary supplements for its stimulant properties, hordenine is believed to support energy and focus by influencing neurotransmitter activity. It is often included in weight management and pre-workout formulas due to its potential to increase metabolic rate and promote fat breakdown. Some traditional applications include use as a mild bronchodilator and for supporting cardiovascular function. However, scientific evidence for these effects is limited, and its safety and efficacy at supplement doses remain under review.
