The Truth About Energy & Focus Supplements – What Science Really Says

Written by Niels Luka, Founder of NÓNE

When it comes to improving energy and focus, there’s no shortage of promises on supplement labels. But what actually works — and what’s just marketing? Let’s look at the science behind ingredients that truly support both mental clarity and physical stamina.

1. Lion’s Mane for Clear Thinking

Lion’s Mane mushroom (Hericium erinaceus) is one of the most researched natural nootropics.
Study: Mori et al., 2009 – PubMed link
Takeaway: In a 16-week human study, participants showed measurable improvements in cognitive function and mental clarity, likely due to the stimulation of Nerve Growth Factor (NGF).

2. Cordyceps for Endurance Energy

Cordyceps species (militaris & sinensis) improve the body’s ability to use oxygen efficiently.
Study: Chen et al., 2010 – PubMed link
Takeaway: Athletes taking Cordyceps saw an average 11% increase in VO₂ max, meaning more sustainable energy without the jitters of caffeine.

3. L-Theanine + Caffeine for Focus without the Crash

While caffeine sharpens alertness, pairing it with L-Theanine smooths the stimulation.
Study: Owen et al., 2008 – PubMed link
Takeaway: This combination improves reaction time and focus while reducing anxiety and the “post-caffeine” crash.

4. Shilajit for Mitochondrial Energy

Shilajit supports ATP production — your body’s cellular energy currency.
Study: Ghosal et al., 1991 – PubMed link
Takeaway: By enhancing mitochondrial function, Shilajit may improve both physical and mental energy levels.

5. Rhodiola Rosea for Stress-Resistant Focus

This adaptogenic herb has been shown to reduce fatigue under stress.
Study: Darbinyan et al., 2000 – PubMed link
 Takeaway: Rhodiola helps maintain mental performance during challenging tasks, especially when you’re tired.

Bottom line: True energy and focus come from balanced brain chemistry, efficient oxygen use, and strong cellular energy production. At NÓNE, we focus on clean, standardized extracts with clinically relevant doses — no fillers, no fake promises.
