Nitrate supplementation has become an increasingly visible area in sports nutrition and active wellness.
Once mainly associated with elite endurance athletes, interest in nitrate-based supplementation has increasingly extended to recreational athletes and active consumers.

Beetroot-derived ingredients have attracted attention because they provide a plant-based source of nitrate and align with wider interest in functional approaches to performance nutrition.
