Ingredients (1.35 grams per serving)
KSM-66 Ashwagandha Extract (600 milligrams per serving)
Ashwagandha root extract is a substance derived from a plant root commonly used in Ayurvedic medicine. It’s known as an adaptogen, which is a compound that causes an imperceivable level of stress in the body that trains it to better handle future stresses.
Research shows that supplementation with ashwagandha root extract . . .
- Increases power and strength[9]
- Reduces cortisol levels from stress[10][11]
- Lowers feelings of stress and anxiety[12][13][14]
- Helps restore lost fertility in men[15]
- Improves immune system function[16]
- Increases cardiovascular endurance[17]
- Protects against pigments that accumulate during Alzheimer’s disease and is thought to have a therapeutic effect in those with the disease[18][19]
The clinically effective dose of ashwagandha root extract is between 50 and 500 milligrams of the patented KSM-66® brand, with a few instances of over 5,000 milligrams of raw powder being used acutely.
PeakATP® (450 milligrams per serving)
Adenosine triphosphate (ATP) is the most basic form of cellular energy in the body. It’s obtained through the conversion of carbohydrates and fat, and it fuels the myriad functions and processes that sustain life and activity, including metabolism and muscle contraction.
PeakATP® is a form of ATP obtained from the glucose in corn that’s chemically identical to what our body produces and thus is available for immediate use.
Research shows that supplementation with PeakATP® . . .
- Improves blood flow to muscles during exercise[20]
- Increases muscular endurance[21][22]
- Reduces perceived exertion[23]
The clinically effective dose of PeakATP® is 400 milligrams.
Alpha-GPC 50% (300 milligrams per serving)
Alpha-glycerophosphocholine (also known as alpha-GPC and glycerophosphocholine) is a compound that contains two molecules known as choline and glycerophosphate.
Choline is a nutrient that’s vital for brain health and function, and glycerophosphate is a substance that helps transport choline to the brain.
When ingested, alpha-GPC increases the activity of a chemical in the brain known as acetylcholine, which is used by nerves to communicate with each other, and provides the brain with glycerophosphate, which can improve its health and function.
Research shows supplementation with alpha-GPC . . .
- Increases power output[24]
- Mitigates cognitive decline as we age[25]
- Increases growth hormone levels[26]
The clinically effective dose of alpha-GPC is between 150 and 1,200 milligrams, with 250-to-600 milligrams sufficient for performance and cognitive benefits and higher doses required for affecting dementia.[27]
No Artificial Food Dyes or Other Chemical Junk
As with artificial sweeteners, studies show that artificial food dyes may cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[28][29][30][31][32]
That’s why we use natural coloring derived from fruits and other foods, as well as natural flavoring.
