"Jost Arriba provides me with an emotional and cognitive boost. It definitely gives me more mental clarity. Shortly after consuming it, I feel increased energy and overall wellness. I also get improved focus and, as a result, my golf game is much better! For the rest of the day, my mood is, typically, uplifted and, generally, positive."

CognatiQ® Coffee Berry Extract

Clinically shown to boost your brain’s key growth protein, BDNF, by 143%. Experience faster decision-making in 60 minutes, sharper impulse control, and increased cognitive stamina. Over time, it significantly improves processing speed.

The ultimate clinical stress shield.

KSM-66® Ashwagandha Root Extract

Backed by 40+ human trials, this premier adaptogen lowers cortisol by 32% to cut stress and cravings. It enhances sleep depth, sharpens executive function, boosts athletic endurance, and builds a calmer, clearer mind.

Nature’s shield for mood and sleep.

Organic Reishi Mushroom Extract

Prized as the "Mushroom of Immortality," Reishi uses adaptogenic triterpenes to lower cortisol and anxiety. It supports non-stimulant brain energy, shields neurons from damage, and accelerates deep, restorative sleep.
