00 / Before lights out

The last thing you eat
decides the night.

T−30 min · Gastric loading

Once you are asleep, nothing else arrives. Whatever amino acid pool you go to bed with is the pool your body works from until morning. That makes the last thing you eat structurally different from everything else you eat in a day.

A whey protein is engineered for the opposite problem. It empties the stomach fast, spikes plasma amino acids inside an hour and then falls away well before the night is over. Micellar casein behaves differently: in the stomach it sets into a soft gel that releases its amino acids gradually. The whole egg alongside it adds fat, which slows digestion further.

Onset.

~5% of the night · Minutes

The lightest stage, and the shortest. Muscle tone drops, breathing slows, and you cross from wakefulness into sleep. Metabolically this is a transition rather than a destination.

What matters here is what is not happening: nothing is being digested quickly. The casein has settled into its slow-release gel and the egg fat is holding the pace down, so the shake you drank half an hour ago is still releasing rather than already spent. This is also where the glycine and the L-theanine are doing their work: on how easily you cross from awake to asleep, and on the core temperature drop that accompanies it.

Core temperature
drops.

~45% of the night · The bulk of it

The largest single share of the night. Heart rate and core temperature fall, and sleep spindles begin, bursts of brain activity associated with consolidating what you learned and practised during the day, motor patterns included.

Digestion is deliberately unhurried here. A shake that sits heavy would be a problem; one that has already cleared would be a wasted opportunity. The lipid-delayed curve is aiming at neither.

03 / N3, the anabolic window

Deep sleep.
This is the one.

~25% of the night · Front-loaded before 03:00

Slow-wave sleep is where the physical repair happens, and it is concentrated in the first half of the night. The largest growth hormone pulse of the twenty-four hour cycle occurs here, shortly after deep sleep begins.

Tissue repair is a construction job, and construction needs materials on site. Amino acids for the muscle, glycine and the fat-soluble vitamins for connective tissue.

Here is a claim we are not going to make. Every egg-based product in this category eventually points at the cholesterol and starts talking about testosterone. Cholesterol is the precursor molecule for steroid hormones, which is a fact about human biochemistry and not a fact about this tub. In healthy people, hormone production is not waiting on what you ate. So the cholesterol stays what it is: a nutrition figure, roughly 300 mg a serving, printed on the front rather than buried. If that ever changes in the literature, you will read it here.

This is the precise hour where a fast isolate has already left the building. It is also the reason the formula was built around a slow curve rather than a fast one.

04 / REM

The second half
belongs to the brain.

~25% of the night · Lengthens toward morning

REM periods get longer with each cycle, so the back end of the night is dominated by them. Memory consolidation and neural housekeeping run here, and the brain is metabolically busy even as the body stays still.

By this point most protein supplements are long finished. A whole-food curve is still trickling. Not dramatically, but the difference between a small supply and none at all is the difference between a net positive and a net negative nitrogen balance in the hours before you wake.
