Each line below was derived from this formula's own record at the time of verification. Nothing here was written by the brand, and nothing can be added that the evidence does not carry.

• Studied in people17 human studies on Zeaxanthin Isomers back this formula, each one cited.
• A mechanism that is settledHow Velvet Bean and Lion's Mane work is settled pharmacology.
• Studied together, not just separatelyLion's Mane and Phosphatidylserine have been studied together, not only separately.
• Recent work on the recordThe most recent study on this record was published in 2026.
• Serving amount inside the studied rangeEach serving carries 500 mg of Lion's Mane, inside the range the published research used.
• A stated daily maintenance amountLion's Mane is here at a daily maintenance amount, which is what a daily supplement is for.
• Why this formatIt is a capsule, so the amount per serving is fixed and travels without measuring.
• The exact form, describedThe label names its forms exactly: Mucuna pruriens seed powder, Dried fruiting body powder, Citicoline sodium. The record says what each one is and what it suits.
• Full label disclosureEvery ingredient on this label carries its own declared amount.
• Where it comes from and how it is madeVelvet Bean is made by botanical.
• Positions this formula already qualifies forThis formula already qualifies for positions beyond the one it is sold into, on the evidence it carries.

The combinations the trials actually measured.

One pairing in this formula has been studied as a combination in human trials. Each finding below is what a named study measured, cited and dated, never written by the brand.

• Lutein + Zeaxanthin IsomersVision

  In the AREDS2 trial long-term follow-up, lutein and zeaxanthin taken together were associated with a modestly lower risk of progression to late age-related macular degeneration, while the trial original primary analysis was not significant.

• Lion's Manewithin about one to two hours of a single doseMeasured within a day

  Two small studies measured a same-day effect. In a randomised, double-blind, placebo-controlled parallel-groups pilot in 41 healthy adults aged 18 to 45, a single 1.8 g dose of lion's mane was followed by quicker Stroop task performance at 60 minutes after dosing (p = 0.005). In a separate randomised, double-blind, placebo-controlled crossover study, a single 1 g dose of Nordic-grown lion's mane was followed by changes in working memory, complex attention and reaction time measures two hours after ingestion. Both samples are small. A third acute crossover in 18 adults using a 3 g dose of a 10:1 fruiting body extract found no effect on composite cognition or mood at 90 minutes, with a change only on an individual pegboard test.

• PhosphatidylserineTested out to 30 weeks of daily useBuilds with daily use

  Phosphatidylserine with DHA was safe and well tolerated in a double-blind placebo-controlled trial of 157 non-demented elderly adults at 300 mg per day for 15 weeks, and at 100 mg per day through a 30-week open-label extension.

• L-Theaninewithin about 45 to 50 minutes of a single doseMeasured within a day

  Two double-blind placebo-controlled crossover trials measured attention at a fixed interval after one oral dose. In 24 overnight sleep-deprived adults aged 20 to 25, a 200 mg dose tested 45 minutes post-dose reduced false alarms on a traffic-scene recognition task and raised target-distractor discriminability. In 27 healthy young adults tested 50 minutes post-dose, 400 mg shortened the parietal P3b event-related potential latency against placebo, with no significant change at 100 or 200 mg. Both trials measured task and electrophysiological markers, not a subjective feeling.

• Caffeine Anhydrouswithin about 45 to 60 minutes of a single doseMeasured within a day

  In a double-blind placebo-controlled crossover trial, 15 resistance-trained women took 4 mg per kg body mass of caffeine 60 minutes before a strength and power battery. Squat one-repetition maximum rose 4.5 percent and countermovement jump height 7.6 percent against placebo. A separate crossover trial in 11 active adults began its cycling tests 45 minutes after a 3 mg per kg capsule and recorded a peak-power increase of about 4 percent on the first day of ingestion.

• Caffeine Anhydrousheld for about 15 to 18 days of daily use, then narrowedBuilds with daily use

  One crossover trial mapped the day-to-day time course in 11 healthy active adults taking 3 mg per kg per day for 20 consecutive days. Peak cycling power in the incremental test stayed about 4.0 percent above placebo for the first 15 days and the difference then lessened. Wingate peak power was still raised on days 1, 4, 15 and 18 by about 4.9 percent. The authors describe the shrinking margin as progressive tolerance. This is one trial with 11 participants.

  In a randomised crossover trial in 24 healthy adults aged 20 to 65, serum lutein rose about 2.4-fold after 15 days of 6 mg per day of lutein from marigold extract and held near that level through day 60.

How each ingredient usually behaves over time.

9 ingredients, from each one's own page.

• Velvet BeanAbout one to two hours

  Often one to two hours after a dose, as a mild lift in drive rather than stimulation. Fertility and hormone measures run on a slower clock, around three months.

• Lion's ManeTwo to four weeks

  Before most people describe a cognitive change. Nothing about it behaves like a stimulant on day one.

• CiticolineAbout four to eight weeks

  Attention measures in trials shift across four to eight weeks of daily use. Some people notice clearer focus inside the first week or two.

• PhosphatidylserineThree to four weeks

  Trials measuring recall and the stress hormone response took readings around that point, and the change builds gradually.

• L-TheanineThirty to sixty minutes

  For most people, with blood levels peaking inside the first hour. Nothing accumulates, so each dose stands on its own.

• Caffeine AnhydrousAbout five minutes

  Fifteen to forty five minutes for most people, peaking around the hour. How long it lasts depends on liver enzyme activity and varies several fold between people.

The same ingredient, carried differently.

What each form is, and where it fits in a formula. Measured findings carry the study that reported them.

• L-theanine

  The single L-enantiomer as a free amino acid, the form found in tea leaf and the form used in essentially all human trials.

  Fits

  Anyone matching what the trial literature actually tested, and anyone formulating with caffeine.

  Trade-off

  Hygroscopic powder with a faint umami taste that can come through in unflavoured drink mixes.

• Caffeine anhydrous

  Dry crystalline free base with no water of crystallisation, close to a hundred percent caffeine by weight

  Fits

  Capsules, tablets and pre-workout powders where an exact milligram figure is needed

  Trade-off

  Potency by volume makes it unforgiving to measure by spoon and it dissolves slowly in cold water. The same potency is what makes accurate dosing possible on a scale

Descriptions of the form itself, read from the cited studies. Not a comparison between products and not a statement about any individual.

Capsule

It is a capsule, so the amount per serving is fixed and travels without measuring.

Because the effect builds and holds only with continued daily use, a steady recurring supply is the practical way to keep it going.
