Spiralyne spirulina tablets can act as a natural energy boost to combat fatigue and can help with mental concentration.
Spirulina is the richest natural wholefood source of complete protein (containing all the essential amino acids) in the world and because spirulina has no hard cell walls, it is much easier to digest than other plant foods.
High-protein foods like spirulina are known to increase energy1234.
A study5 (Kalafati M, et al.) published by the official journal of the American College of Sports Medicine, Medicine & Science in Sports & Exercise showed that spirulina induced a significant increase in exercise performance and fat oxidation. In the study, nine moderately trained males took part in a double-blind, placebo-controlled, counterbalanced study. Each subject received 6 grams of spirulina or 6 grams placebo for 4 weeks. Each subject ran on a treadmill at an intensity of 70-75% of their VO2max for 2 hours and then at 95% VO2max to exhaustion. Time to exhaustion was significantly longer after spirulina supplementation; 2.05 minutes and 2.7 minutes with spirulina supplementation (above).
Ingestion of spirulina increased fat oxidation rate by 10.9% during the 2 hour run compared with the placebo trial (left). The antioxidant properties of spirulina may have resulted in increased fat oxidation, which then may have resulted in an increased exercise performance.
