Nitrate and Beetroot Juice: JISSN Position Stand

## Summary

The JISSN Position Stand by Stanelle ST et al. from 2019 analyzes dietary nitrate supplementation and was published in the Journal of the International Society of Sports Nutrition.

Study Background

This position stand examines the effects of nitrate (primarily from beetroot juice) on nitric oxide production and athletic performance.

Key Findings

The position stand shows: - Optimal dose: 300-600mg nitrate (approx. 500ml beetroot juice) - Timing: 2-3 hours before training for peak plasma nitrite - Mechanism: Nitrate → Nitrite → Nitric Oxide (NO) → Vasodilation - Performance effects: 4-25% improvement in high-intensity exercise - Responders vs. Non-Responders: Individual variation in response

Methodology

The position stand is based on meta-analyses and controlled studies on nitrate supplementation.
