Creatine is an amino acid that plays a critical role in cellular energy production. Daily supplementation may help improve muscle performance and cognitive function.
We collaborated with registered dietitians and human performance specialists from elite professional sports teams to create a protein supplement of the highest quality for their athletes.
Protein is a fundamental macronutrient that is a critical building block of the human body and is essential to support the growth, development, and recovery of muscles. Our formula is made from a precise blend of pea and rice proteins, which yields a complete amino acid profile.
Sleep is a combination of three expert-curated ingredients designed to synergistically help improve your rest: Magnesium L-Threonate, L-Theanine, and Apigenin.
The Foundational Sleep Stack provides three potent ingredients, Magnesium L-Threonate, Apigenin, and L-Theanine, that prepare you for a good night's rest.
Magnesium L-Threonate helps increase synaptic density and promotes synaptic plasticity, which aids cognitive function and long-term cognitive health.
L-Theanine is a naturally occurring, non-protein amino acid found in tea that easily crosses the blood-brain barrier and can support the activation of alpha waves.
Apigenin is a bioflavonoid compound found in various fruits, vegetables, and herbs, such as chamomile and parsley, which can help reduce stress and promote higher-quality sleep.
