Rhodiola rosea (minimum 5.1% rosavins) - An adaptogen that is native to the high altitude Polar Regions of Europe and Asia. Rhodiola rosea containing minimum 5.1% rosavins is the most potent strain available worldwide. In a recent double blind placebo controlled randomized study, it was scientifically documented that Rhodiola rosea increases VO2 Max in addition to significantly reducing fatigue. Recent research documents rhodiola rosea increases maximum oxygen intake and increased run time to exhaustion.

Cordyceps sinensis (NOW with 8% Cordycepic acid) - An adaptogen that is primarily native to the plateaus of China and Tibet above 12,000 feet. In addition to scientific documentation that confirms it’s ability to increase energy and endurance, the legendary running coach, Ma Junren (Newsweek. Sept 27,1993), attributes many of the long distance running world records to the athlete’s use of Cordyceps sinensis. When evaluating Cordyceps sinensis, the active ingredient is Cordycepic acid or Mannitol. 7% Cordycepic acid is generally regarded as the most potent available, Kona Endurance supplements are now formulated with 8% Cordycepic acid.

Branched Chain Amino Acids - Precise 2:1:1 ratio of L-Leucine, L-Isoleucine, L-Valine. Science documents these amino acids benefit the endurance athlete by increasing endurance, delaying fatigue and reducing muscle fatigue. It is important to note that branched-chain amino acids can be converted into glucose and used as fuel for endurance activities, very beneficial for the endurance athlete. A recent study documented BCAA supplementation was very effective in improving time-trialing performance in trained cyclists.

Citrulline Malate - Research show that Citrulline, a very unique amino acid, has been scientifically documented to increase endurance and increase aerobic capacity. It is a key intermediate in the urea cycle, the pathway by which mammals excrete ammonia. It is scientifically documented that Citrulline Malate has lead to significant reductions of fatigue and increases in energy production. The metabolic actions of Citrulline Malate clearly explain the research that documents it's ability as a performance enhancer in benefiting the endurance athlete.
