The science behind FOCUSED

Three ingredients. Published research. Zero guesswork.

Every milligram in FOCUSED is backed by peer-reviewed research, and we publish the exact dose of each one.

Our Philosophy

The Supplement Industry Sells Complexity. We Sell Clarity.

Most energy and focus supplements pack 15-20 ingredients into a "proprietary blend" — a legal loophole that lets them list ingredients without revealing doses. You could be getting 200mg of L-theanine or 2mg. You'd never know.

And if you're turning to matcha for clean energy? A 2024 Food Chemistry study found lead, arsenic, and cadmium in 12% of matcha samples tested. Because you consume the ground whole leaf, you ingest everything in it — including contaminants.

FOCUSED was built on a different principle: radical simplicity. Three ingredients, each at a published dose, each backed by peer-reviewed research, and every batch third-party tested for purity. When you can verify every ingredient and every dose, trust isn't a marketing claim — it's a fact.

How It Works

What Happens After You Take FOCUSED

Three ingredients working in sequence — immediate clarity that builds into sustained, crash-free energy.

1
0–15 Minutes

Absorption

Natural caffeine from green tea begins entering the bloodstream. L-theanine crosses the blood-brain barrier and starts promoting alpha brain wave activity — the neural pattern associated with calm, focused attention.

L-Theanine Natural Caffeine
2
15–45 Minutes

Peak Focus

Caffeine and L-theanine reach full synergy. Clinical studies show this combination improves task-switching accuracy, sustained alertness, and reduces susceptibility to distraction — all without the jitters or anxiety of caffeine alone.

L-Theanine + Caffeine synergy
3
1–4 Hours

Sustained Performance

L-theanine modulates caffeine's stimulant effect, preventing the sharp crash associated with coffee. Energy stays stable and focused. Spirulina's phycocyanin provides antioxidant protection, supporting cellular health during extended cognitive work.

Spirulina L-Theanine Caffeine

Weeks 1–4

Cumulative Benefits

Spirulina's anti-inflammatory and antioxidant compounds accumulate with consistent daily use. A 2022 clinical trial showed spirulina significantly improved cognitive function scores over 12 weeks. The longer you take it, the more it works.

The Formula

3 Ingredients. Every Dose Justified.

Click any ingredient to see the clinical rationale, evidence, and dose justification.

Organic Spirulina
250mg
Clinical range: 250–3,000mg in studies
+

Blue-green algae (Arthrospira platensis) rich in phycocyanin — one of nature's most potent antioxidants. Phycocyanin has been shown to reduce oxidative stress, lower inflammatory markers (CRP, IL-6, TNF-α), and support cognitive function.

Clinical Evidence

A 2022 randomized, double-blind, placebo-controlled trial found that spirulina extract significantly improved visual learning, visual working memory, and vocabulary scores in adults with mild cognitive impairment. A separate 2023 trial demonstrated that 12 weeks of spirulina supplementation improved cognitive function scores and reduced inflammatory markers.

Organic cultivation USDA Organic GRAS
L-Theanine
140mg
Clinical range: 100–400mg in studies
+

Non-essential amino acid found naturally in Camellia sinensis (tea plant). Promotes alpha brain wave activity — the same neural pattern observed during meditation — creating focused attention without sedation. When combined with caffeine, L-theanine smooths the stimulant effect, reducing jitters while enhancing focus.

Clinical Evidence

A landmark study (Nutritional Neuroscience, 2008) found that L-theanine combined with caffeine significantly improved task-switching accuracy and alertness in 44 adults. A separate study in Biological Psychology showed the combination increased target discriminability and lowered alpha power, indicating enhanced attentional focus at the neurophysiological level.

Naturally derived Green tea origin GRAS
Natural Caffeine (from Green Tea)
70mg
Clinical range: 40–200mg in studies
+

Naturally occurring caffeine extracted from Camellia sinensis leaves — the same source as matcha and green tea, but without consuming the ground leaf. At 70mg, this is approximately half a cup of coffee — enough for meaningful alertness, low enough to avoid overstimulation.

Clinical Evidence

The caffeine + L-theanine synergy is one of the most replicated findings in cognitive supplementation research. Multiple placebo-controlled studies consistently show that the combination outperforms either compound alone for attention, focus, and cognitive performance. Green tea caffeine provides a smoother energy curve compared to coffee.

The Published Evidence

Every ingredient is backed by peer-reviewed clinical studies.

Nutritional Neuroscience • 2008

The combination of L-theanine and caffeine improves cognitive performance and increases subjective alertness

Key Finding: 97mg L-theanine + 40mg caffeine significantly improved task-switching accuracy and increased alertness in 44 young adults vs. placebo. The combination outperformed either compound alone.
