What Powers STEM?
Meet our hero ingredients behind clean, crash-free energy.
STEM is powered by ingredients that work with your body, not against it.
We’ve blended natural nootropics and adaptogens to create an energy drink that delivers clean fuel, sharp focus, and real resilience, without the crash.
🧠 Nootropics like Lion’s Mane and L-theanine support focus, clarity, and calm energy
🌿Adaptogens like cordyceps help the body manage stress, boost stamina, and aid recovery
⚡CoffeeBerry® delivers natural caffeine with antioxidants for smooth, clean energy

CoffeeBerry
We have love for all and the coffee berry is no different. You may be thinking what is the word ‘berry’ doing after ‘coffee’.
“Coffeeberry® Energy is a patented coffee fruit caffeine intentionally designed to retain native antioxidant polyphenols from the whole coffee fruit and deliver standardized levels of cleaner, more sustainable caffeine.”

L - Theanine
A naturally occurring amino acid primarily found in green tea.
It improves sleep and promotes relaxation whilst also helping to reduce stress.
L-theanie has also been shown to improve cognitive function (focus and attention), particularly when paired with caffeine as well as blunting both caffeine’s blood-pressure-increasing effects and its sleep-disrupting effects.

Lion's Mane
Hericium Erinaceus
Revered for its cognitive-enhancing properties, Lion's Mane supports mental clarity and focus, making it perfect for those long workdays or intense study sessions.
- Boost mental performance
- Clear brain fog
- Elevate focus

Cordyceps
A potent powerhouse designed to fuel both the body and mind!
Known for its ability to enhance stamina and oxygen uptake, Cordyceps has long been used to boost physical endurance and fight fatigue.
This unique mushroom also helps regulate energy at the cellular level, promoting natural, sustained vitality without the jitters.
