The Formula

Every active. Honest doses.

No proprietary blends. Every milligram is on the label, dosed at the level used in the clinical research it's based on.

Lion's Mane

Hericium erinaceus (organic fruiting body)
500 mg · 30% beta-glucans

The most-studied mushroom for cognitive function. Lion's Mane contains hericenones and erinacines — compounds that have been shown to stimulate Nerve Growth Factor (NGF) in vitro and in animal studies. Human trials in older adults with mild cognitive concerns show modest but consistent improvements in cognitive scores over 16-week courses.

Job: Support neural plasticity and cognitive function.
Studies: Mori 2009, Saitsu 2019.

Cordyceps

Cordyceps sinensis (organic fruiting body)
500 mg · 7% cordycepic acid

A traditional adaptogen with research evidence for ATP production and cellular energy metabolism. Particularly studied for endurance and mental stamina endpoints — useful during sustained cognitive work or training periods. Used in Chinese medicine for over 2,000 years.

Job: Support cellular energy and sustained mental endurance.
Studies: Chen 2010, Hirsch 2017.

Reishi

Ganoderma lucidum (organic fruiting body)
500 mg · 30% polysaccharides

Among the most-studied adaptogenic mushrooms for stress modulation. Reishi's triterpenes and polysaccharides have been studied for cortisol regulation, sleep quality, and immune function — three layers that underpin sustained cognitive clarity.

Job: Modulate stress response; support sleep architecture.
Studies: Wachtel-Galor 2011, Chu 2012.

Bacopa Monnieri

(50% bacosides)
300 mg · standardised extract

A well-studied nootropic with the largest evidence base for memory and learning endpoints in healthy adults. The bacosides are believed to support cholinergic function and synaptic plasticity. Effects accumulate over 8-12 weeks of consistent use — Bacopa is not a fast-acting compound.

Job: Support memory consolidation and learning.
Studies: Stough 2008, Calabrese 2008.

L-Theanine

From green tea (Suntheanine)
200 mg

An amino acid that promotes calm focus without sedation. Studied extensively for combined effects with caffeine — together producing improved focus without the jittery edge of caffeine alone. Effective within 30-45 minutes of consumption.

Job: Support calm, sustained focus; reduce caffeine-related anxiety.
Studies: Owen 2008, Haskell 2008.
What's Not In Here

A short list, on purpose.

We left a lot of common "Daily Cognitive Support · Adults 35+" stalwarts out of Claros. Here's why.

Not Included

Caffeine

Not in Claros. We chose to keep the formula non-stimulant — pair Claros with your usual coffee or tea if you want the caffeine + L-theanine combination, without forcing the dose into the formula.

Not Included

Modafinil-style 'racetams'

Synthetic nootropics (piracetam, aniracetam, etc.) — outside the regulatory framework for food supplements in the U.S., and outside our evidence comfort zone for daily use.

Not Included

Mushroom mycelium / grain extracts

Cheaper than fruiting body, but with substantially lower beta-glucan and active-compound content. We use only fruiting body extracts.

Other Information

Capsule shell, fillers, allergens.

Capsule: vegetarian HPMC.
Mushroom source: organic fruiting body extracts (not mycelium-on-grain).
Fillers / flow agents: microcrystalline cellulose, magnesium stearate (vegetable source).
Free from: gluten, dairy, soy, nuts, GMOs, artificial colours, artificial sweeteners, stimulants.
Allergen note: manufactured in a facility that also handles tree nuts.
