Two ingredients. Nothing else doing the work.
Magnesium glycinate — for the body's wind-down
Magnesium is one of the most essential minerals in the human body, yet most adults don't get enough of it through diet alone. Soil depletion, processed food, caffeine, alcohol, and stress all chip away at the body's magnesium stores.
When magnesium drops below optimal levels, the nervous system loses one of its primary "calming" co-factors. Muscles cramp. The body struggles to drop into deep sleep. Stress feels heavier than it should.
The form matters more than the marketing
Not all magnesium is created equal. Magnesium oxide — the cheap form in most pharmacy multivitamins — is poorly absorbed and notorious for digestive upset. We use magnesium glycinate, which binds elemental magnesium to the amino acid glycine. Two things happen:
- The body absorbs it more readily, with less digestive disturbance.
- Glycine itself has independent calming properties on the nervous system, contributing to the relaxation effect.
It's the form sleep researchers reach for, and it's the form we chose.
What it supports
- The body's natural transition from "alert" to "rest"
- Muscle recovery after physical exertion
- Healthy sleep architecture, including time spent in deep sleep
- A balanced stress response
L-theanine — for the mind's wind-down
L-theanine is an amino acid found almost exclusively in tea leaves. It's the compound responsible for the famously calm-but-clear feeling people describe after drinking matcha or green tea — alert without being wired, calm without being foggy.
Mechanistically, L-theanine supports the brain's alpha-wave activity (associated with relaxed wakefulness and meditation), modulates the body's stress response, and contributes to natural GABA pathways — the same calming neurotransmitter system that benzodiazepines target, but without the sedation, tolerance, or dependence.
What it supports
- A relaxed mental state without sedation
- A softer caffeine experience (the reason green tea hits differently to coffee)
- Easier transition into sleep — quiets the racing-mind feeling
- A measured response to acute stress
Why we paired them — and didn't add anything else
Most sleep supplements throw seven, eight, ten compounds into a single capsule. It looks impressive on a label. It rarely means more is happening inside the bottle.
Magnesium glycinate works on the body. L-theanine works on the mind. Most people who struggle to sleep are struggling with one of those two — or both. Adding melatonin shortens sleep latency in some people but introduces grogginess and disrupts the body's own melatonin rhythm with prolonged use. Adding valerian, hops, or chamomile sounds botanical but adds variability without strong consistent evidence at supplement doses.
We chose to do two things, in evidence-backed doses, exceptionally well.
On side effects — and the honest comparison
One of the reasons people first try Unwind is what we didn't put in it.
Compared to melatonin: Magnesium glycinate and L-theanine don't act on the brain's melatonin receptors, so they don't carry the same risk of next-morning grogginess. They also don't disrupt the body's own melatonin rhythm with long-term use — something the research is increasingly cautious about with daily melatonin supplementation.
Compared to sedatives and prescription sleep aids: Neither ingredient is a central nervous system depressant. You won't wake up dulled. There's no recognised dependence profile with magnesium or L-theanine at the doses Unwind uses.
What you might notice (rare, mild):
- Magnesium glycinate is the gentlest common form of magnesium, but in some people higher doses can cause loose stools. The dose in Unwind is well within the comfortable range for almost everyone.
- L-theanine is well tolerated up to 400mg daily in healthy adults. At our 200mg dose, side effects are extremely rare in the published literature.
Who should speak to a doctor first:
If you're pregnant, breastfeeding, under 18, on blood pressure medication, on prescription sedatives, or have kidney disease, please talk to your healthcare provider before starting any supplement — Unwind included.
