The Science Behind SERA
Every ingredient has a reason. Every reason has research behind it.
Alpha-GPC
A source of choline, included to support normal cognitive function
Alpha GPC is a source of choline, which contributes to normal cognitive function. A 2024 randomised controlled trial found that Alpha GPC supplementation was associated with improved cognitive performance scores and reduced task completion time compared to placebo in healthy adults.
L-Theanine
Naturally sourced, included to support calm and focus
An amino acid naturally found in green tea. At 200mg, the exact dose in SERA, a 2024 double-blind RCT found associations between L-Theanine supplementation and improved attention and reduced distractibility in healthy adults. A separate randomised placebo-controlled study found associations with working memory and executive function following supplementation.
Taurine
One of the body's most abundant amino acids, included for cellular support
One of the most abundant free amino acids in the body. Taurine plays a role in cellular fluid balance and normal cellular function. Peer-reviewed research associates taurine supplementation with supporting normal cognitive function. It's in SERA as foundational support, not a stimulant.
Electrolytes
The foundation of effective hydration: sodium, potassium, magnesium
Electrolytes are essential for normal hydration. A 2025 randomised crossover trial found that electrolyte drinks were more effective at maintaining electrolyte balance during exertion compared to water alone. SERA's electrolyte profile is designed to support daily hydration needs, not just physical recovery.
Hi, I'm Lewis.
I started SERA because I was tired of the trade-off. Coffee gave me a lift, then a crash. Energy drinks were worse: sugar, artificial stimulants, and a comedown that made the afternoon harder than it needed to be.
I wanted something that just worked. Clean electrolytes to actually hydrate, and ingredients backed by research to support real focus, not artificial energy. No caffeine. No sugar. No crash.
SERA is what I built for myself first. Every batch is made in Australia, and every sachet is designed around the same moment: 2:17pm, when the day gets long and you need to think clearly without reaching for something that will let you down an hour later.
Thanks for being here from the start.
