The Essential Routine : Science

The Scientific Reference Library

All 44 ingredients in The Essential Routine and their 119 peer reviewed research references.

Nothing in The Essential Routine is in the formula because it tested well in a focus group. Every ingredient earned its place by mechanism: a named job, at a dose we can point to, in a form the body can actually use. This is the library we built the system from, opened up.

Why This Library Exists

A Label Tells You What Is in the Bottle. It Does Not Tell You Why.

It does not tell you why that ingredient is there, why that form was chosen over a cheaper one, or what the research actually found.

The Essential Routine is a cofactored system. Each ingredient is chosen partly for what it does on its own and partly for what it lets another ingredient do: Riboflavin 5' Phosphate so the folate can be used, Vitamin K2 so the Vitamin D3 has somewhere to send the calcium, L-Theanine so the caffeine does not arrive alone. A system built that way only holds up if the evidence holds up. So we wrote all of it down, and we are showing you the whole thing.

How to Read an Entry

Four Parts, in the Same Order Every Time

1. Research Summary

What the study set out to test, who ran it, and what they found, in plain language.

2. Key Findings

The specific results that bear on The Essential Routine, with the numbers as the researchers reported them.

3. Supporting Excerpts

Quoted directly from the paper, so nothing rests on our paraphrase.

4. E4E Formula Connection

Why this study put this ingredient, at this dose, in this step.

Each entry opens with the full citation, the journal, the publication date and a public access link to PubMed or the publisher. If we cite it, you can go read it.

The Index

Three Formulas, Three Points in the Day

Here is every ingredient in each one, and the job it is there to do. The plus on any ingredient opens its own page, with every reference behind it in full.

STEP 1 :: REFUEL Start of Day

23 Ingredients

Rebuilds the base the day before spent: the full vitamin and mineral foundation, the methylation cofactors that let those vitamins actually be used, and a layered micro dose energy architecture instead of a single hit of caffeine.

  1. RF.01B1 Benfotiamine (Vitamin B1) 1.3 mg110% DV3 References A fat soluble form of B1 that reaches tissue the way the common thiamine salts do not.

  4. RF.04Niacinamide (Vitamin B3) 15 mg94% DV3 References The NAD+ precursor that funds energy metabolism and DNA repair, without the flush that comes with niacin.
  5. RF.05Pantothenic Acid (Vitamin B5) 5 mg100% DV2 References Precursor to Coenzyme A, the hub where energy metabolism, fatty acid synthesis and acetylcholine production meet.
  6. RF.06Pyridoxal 5' Phosphate, P5P (Vitamin B6) 1.2 mg70% DV3 References The active form of B6, skipping liver conversion to feed serotonin, dopamine and GABA synthesis and more than 140 enzyme reactions.
  7. RF.07Biotin (Vitamin B7) 30 mcg100% DV2 References Coenzyme for the five carboxylases that run fatty acid metabolism, amino acid processing and gluconeogenesis.
  8. RF.08Calcium L-5-Methyltetrahydrofolate (Vitamin B9) 560 mcg140% DV4 References The only folate form that crosses the blood brain barrier and enters the methylation cycle without needing the MTHFR enzyme to convert it first.

  17. RF.17TeaCrine, Theacrine 95 mg*3 References Sustained neuro energetic support that does not build tolerance the way caffeine does.
  18. RF.18Dynamine, Methylliberine 75 mg*2 References Fast onset activation that layers underneath TeaCrine's slower, longer curve.
  19. RF.19L-Theanine 75 mg*3 References Promotes alpha wave activity for calm focus, holding the stimulants in check without sedation.
  20. RF.20Beta-Alanine 250 mg*6 References The rate limiting substrate for muscle carnosine, which buffers intracellular pH when the physical work gets hard.
  21. RF.21Creatine HCL 1,520 mg*3 References Phosphocreatine buffering, for cognitive function under sleep loss and for high intensity capacity.
  22. RF.22Nu-MAG(R) 65.8 mg*1 Reference A rice based delivery matrix replacing magnesium stearate, protecting blend uniformity so every capsule carries the full formula in its intended ratios.
  23. RF.23Bamboo Extract, 70% Silica 14.2 mg*Cross Referenced Natural moisture control inside the capsule, and bioavailable silica toward the day's combined total.
STEP 2 :: RECHARGE Midday

11 Ingredients

Carries the afternoon by extending what REFUEL started rather than starting over. Every dose here is calibrated against the Start of Day amount, so the day's running totals land inside the studied ranges.

  1. RC.04Green Tea Extract 140 mg*3 References EGCG and catechins for cognitive support, thermogenesis and neuroprotection, working with the L-Theanine and caffeine alongside it.
  2. RC.10TeaCrine, Theacrine 200 mg*2 References Combines with REFUEL's 95 mg for 295 mg across the day, inside the clinically studied range for sustained neuro energetics.

* Daily Value not established.

Step 4. Repeat.

The fourth step is not a capsule. It is the one that compounds.

A Note on the Last Three

Delivery Ingredients Are Documented Too

Nu-MAG(R), Bamboo Extract and MCT Oil sit under Other Ingredients on the label. That placement reflects a labeling threshold, not a ranking. They replace magnesium stearate and synthetic flow agents, and they are documented here with the same rigor as everything else, because a formula that does not hold its ratios inside the capsule is not a formula.
