Benefits

What you’ll notice, and when.

Some of it the first morning. Some of it by week three. Some of it you never feel, and it matters most. Everything here comes from a human trial at or under the dose in your mug.

The first hour
Focus arrives.

Coffee with L-theanine, the amino acid in green tea that takes the edge off caffeine: sharper attention and less distraction than coffee alone, from the first cup30.

In the mug
Coffee, L-theanine, rhodiola
The first morning
Energy, on two fuels at once.

Your brain can burn glucose and ketones side by side, and gets more from both than from either alone. The mug carries both: 5 grams of sugar, and MCT oil (a coconut-derived fat) your liver turns into ketones within the hour40. Creatine, at 5 g, fuels the brain as well as the body41. No crash at hour four.

In the mug
Sugar, MCT oil, creatine
Weeks two to four
The deeper fatigue lifts.

Rhodiola acts within two weeks51, creatine within the first week41. Underneath, NAD+ — the coenzyme every cell uses to make energy, and which falls with age — doubles in the blood by day fourteen2, while creatine keeps building in the brain3.

"Way more fatigued without it. Those couple weeks I was drinking your coffee daily, I felt amazing."

— Pilot customer, two weeks on, one week off

The trials see the same thing: in the one lion’s mane study that kept measuring after dosing stopped, scores fell within four weeks39. This works while you take it.

Creatine, NMN
Month three
Recall sharpens.

The last to arrive, on a twelve-week clock: long enough for the brain to replace nine-tenths of its energy machinery33, with lion’s mane supplying the growth signal to build it well. A protocol, not a pick-me-up.

Every day, unfelt
The cycle, running.

Below sensation, not below measurement. By day your cells signal for new mitochondria, build them, fuel them, and protect them; by night they clear the worn ones out. Clearing fades most with age, and spermidine measurably raised it in adults over 65, at a quarter of our dose32. One morning mug carries all five stages.

Apigenin. CD38 is the enzyme that uses up most of the body’s NAD+. Apigenin slows it. In animal studies NAD+ rose in tissue within days46. Taken every morning, apigenin builds in the blood over three weeks47.

Along the way

What else it does.

Each one measured in people, at or under the amount in the mug. The marker on each card is the point on the timeline above where the trial found it.

Weeks two to four
Stress and mood

Lower anxiety, better mood, and better sleep in healthy adults after a month21. Rhodiola and L-theanine were each studied at our dose.

L-theanine, rhodiola
Week six
A lower heart-risk marker

Six weeks of betaine at our dose lowered homocysteine — an amino acid that tracks cardiovascular risk when high — by 12% in adults who started high23.

Betaine
Weeks ten to twelve
Healthy glucose metabolism

Women with prediabetes handled glucose better after ten weeks of NMN, at a quarter of our dose37. Twelve weeks of creatine with exercise lowered HbA1c, the three-month blood-sugar marker, in type 2 diabetes38. Both were the main thing each trial set out to measure.

NMN, creatine
Month three
Memory

Memory improved over twelve weeks of PQQ in healthy adults, at exactly our dose26, and over sixteen weeks of lion’s mane in older adults whose recall had begun to slip39. Where the decline had gone further, a year of erinacine A at half our dose improved cognition and daily function1. The deficit is what it corrects.

Month three
Mental fatigue

Twelve weeks of ubiquinol, the active form of CoQ10, at exactly our dose left adults with everyday fatigue less tired and less sleepy after a demanding mental task27.

Ubiquinol
Weeks six to eight
Blood pressure

Six to eight weeks of pterostilbene at exactly our dose lowered systolic blood pressure by 7.8 mmHg in adults with high cholesterol35.

Strength

With resistance training, creatine builds strength and lean mass in young and older adults alike — the most replicated finding in sports nutrition, across several hundred trials34. Our 5 g is the full maintenance dose, inside the range the brain studies used.

Essential Plus

Essential Plus: everything in Essential along with extra support for immunity, joints, mood, and memory under stress.

Immunity

Reishi β-glucan raised T-cell and natural-killer counts in 135 healthy adults, at exactly our dose56. In adults whose immune markers ran low, eight weeks of cordyceps raised first-line activity54.
