A shot of fast-acting natural fructose (fruit sugar) goes straight to work building your energy levels back up while the maltodextrin is quickly absorbed and sent to your muscles. Vital electrolytes keep your blood chemistry in line and hydration levels stable. Calcium keeps your muscles humming and caffeine adds an extra kick to your power.
Complex carbs in the form of maltodextrin (70-80% of the complex/simple carbohydrates blend) help you maintain glucose levels over time. Citrates (potassium citrate, sodium citrate and citric acid) help speed the conversion of these carbs into energy molecules and mitigate performance-sapping acid build-up in muscles. Branched chain amino acids (BCAAs) leucine, valine and isoleucine, serve as another fuel source, aid in recovery and can improve mental performance and reduce fatigue by limiting the central nervous system's production of serotonin. Histidine, an essential amino acid, acts alongside the citrates as a buffer that helps neutralize lactic acid build-up in muscles.
Antioxidant vitamins C & E defend muscles from assault by free radicals. Chamomile works as an anti-inflammatory during and after exercise. Ginger soothes the stomach. Sea salt supplies a host of minerals.
