The science

What is in the bottle and why.

Deep Sleep & Restore is built from five ingredients with published research behind each of them. This page explains what each one is, why we chose the form we did and what the evidence currently says. It is written for people who like to know, not to persuade.

Our standard

Our formulation standard.

01

Evidence first

An ingredient has to have human research behind it, not a good story. We read the studies, not the summaries.

02

The right form

Magnesium is not one thing. The form decides absorption, tolerance and what it does. We choose the form for the job.

03

Amounts that matter

We include the amount the research used, or we leave it out. There are no sprinkles for the label.

04

Sense

If the science says yes but it does not fit a real evening, a real routine or a real body, it does not go in.

Ingredient deep dives

Heart, nervous system, muscle function.

Magnesium Taurate

1,000 mg, providing 80 mg elemental magnesium

Magnesium taurate is magnesium bound to taurine, an amino acid concentrated in the heart, muscle and nervous system. We chose it because taurine and magnesium appear to work along similar pathways in supporting normal cardiovascular and nervous system function and because the taurate form is well tolerated. At 1,000 mg it provides 80 mg of elemental magnesium, roughly a third of the serving total.

Magnesium bound to taurine. Taurine is an amino acid found in high concentration in the heart and nervous system. This form is chosen for how well it is tolerated and how it supports normal muscle and nerve function through the night.

Sleep quality, calm.

L-Glycine

600 mg

Glycine is the simplest amino acid and one of the most abundant in the body, a building block for collagen and a neurotransmitter in its own right. We include 600 mg in the evening because studies in healthy adults have looked at glycine taken before bed and its relationship with subjective sleep quality and next day alertness.

An amino acid the body uses everywhere, from collagen to neurotransmission. Taken in the evening it supports the natural fall in core body temperature that accompanies good sleep. It pairs with the bisglycinate form of magnesium below.

Sleep, nervous system, muscle recovery.

Magnesium Bisglycinate

467 mg, providing 140 mg elemental magnesium

Two glycine molecules chelated to one magnesium. This form is chosen for gentleness on the stomach and for the research attention magnesium has received in relation to sleep quality, muscle relaxation and normal nervous system function. At 467 mg it provides 140 mg of elemental magnesium.

Magnesium bound to two glycine molecules. It is among the gentlest forms on the stomach and one of the most studied for supporting relaxation and sleep. Two magnesium forms, one purpose: a full 220 mg of elemental magnesium per serving without the digestive cost of oxide or citrate.

Relaxation without drowsiness.

L-Theanine

100 mg

Theanine is the amino acid that gives green tea its calm character. At 100 mg it is included to support a relaxed, settled state without drowsiness, which suits the half hour before bed when the goal is to put the day down rather than to be sedated.

The amino acid found in green tea leaves. It supports a calm, settled state of mind in the evening, the kind that makes it easier to put the day down.

Evening calm.

Apigenin (98 percent pure)

50 mg

Apigenin is a flavonoid found in chamomile, parsley and celery. We include 50 mg at a purified 98 percent standard because chamomile has a long tradition as an evening herb and apigenin is the compound most associated with that use.

A flavonoid found in chamomile and parsley. Included at a purified 98 percent standard to support the unwinding phase before sleep.

What we deliberately left out.

No melatonin

Melatonin is a hormone with a specific job and a specific regulatory status in New Zealand. Deep Sleep & Restore works with the systems that support sleep rather than supplying the hormone itself.

No sedative herbs

Nothing here is designed to knock you out. Sedation and restorative sleep are not the same thing.

No proprietary blend

You can see every amount. That is the whole point.
