Key nutrients for next-level performance

Amino Acids

The building blocks of life! Amino acids are tiny organic compounds that team up to form proteins, critical for muscle growth, maintenance, and repair. Without an adequate supply of amino acids, your body will use existing muscle tissue as fuel to support daily activities and workouts which results in muscle breakdown and the loss of muscle mass. Essential Amino Acids are only obtained through food and supplementation while non-essential amino acids are produced naturally by the body.

Rhodiola Rosea & Caffeine

Rhodiola rosea is an adaptogenic herb that has been used for hundreds of years to increase both physical and mental stamina. When combined with the natural caffeine found in green tea, it helps maximize both physical endurance and mental focus during exercise. ​​​​​​​

Carnosyn Beta Alanine and L-Citrulline

Beta Alanine is another ingredient with benefits tied to improved athletic performance by releasing carnosine into working muscle to buffer the onset of lactic acid build up during high intensity exercise. Carnosyn Beta Alanine and L-Citrulline work in tandem to support blood flow to your muscle cells. More blood flow to muscles means increased oxygen and nutrients to pump your workouts. All this can result in increased endurance, reduced fatigue, and a boost of performance during exercise.

Spirulina

Spirulina contains phycocyanin - a phytonutrient that is part of spirulina’s light harvesting pigment complex - which acts as an antioxidant and contributes to energy-yielding metabolism.
