The researchers noted that "acute ingestion of SPB [Setria Performance Blend]* after eight days may enhance blood flow, L-citrulline, and L-arginine plasma concentrations after high-intensity exercise, which may enhance performance." *Setria Performance Blend is now referred to as Setria for Sport This study demonstrates the specific benefits for endurance athletes, especially in terms of improved blood flow, oxygen delivery, and recovery capacity following high-intensity exercise

Recommended Protocol For most athletes, a daily protocol works best: Daily dose: 200mg Setria Glutathione + 2g L-citrulline Timing: 60-90 minutes before exercise on training days Consistency: Maintain daily supplementation even on rest days to keep nitric oxide production optimized Duration: Studies show benefits beginning within days, with optimal results after 4-8 weeks of consistent use Safety Considerations One of the standout features of Setria For Sport is an excellent safety profile, making it appropriate for consistent use as part of a long-term supplementation strategy
One of the most important is Glutathione Peroxidase (GPx)
