For the nights you're tired but not switched off. Two capsules, thirty to sixty minutes before bed, as a deliberate cue that the day is over.
The peptide is the reason this exists. Nuritas® screened food proteins with AI for the specific fragments that lower cortisol, and PeptiSleep® is what they found. In an 8-week randomised, placebo-controlled trial, 250mg a night produced 38 minutes more total sleep, 13 minutes more deep sleep and a 12% improvement in perceived sleep quality.
Around it: magnesium bisglycinate at 150mg, L-theanine at 200mg and apigenin at 50mg. Bought separately that's three orders and three tubs — and the peptide isn't sold separately in Britain at all.
Why you're still awake
You're not bad at sleeping. Your cortisol is too high.
Cortisol is the hormone that keeps you alert. It's meant to peak in the morning and drop away through the evening, so that by the time you're in bed your body has been told the day is over.
Late work, late training, screens and stress keep it up. So you get into bed tired but not switched off — lying there with a body that hasn't stood down.
PeptiSleep® is a brown-rice peptide. Nuritas® found it by screening food proteins with AI for the specific fragments that lower cortisol, then made that one at scale. It's not a sedative and it's not melatonin — it doesn't knock you out, it lets you switch off.
The trial
What happened in the trial
Three tubs, three orders. Or one jar.
If you're already buying magnesium, theanine and apigenin separately, this is the same shelf in one jar — plus the one thing none of them do.
The evidence
Clinically studied plant peptides.
Two peptides, found by screening food proteins with AI and then tested in human trials against placebo. These are the results their developer, Nuritas®, publishes.

What to expect
What the first month looks like
Night one
Two capsules, thirty minutes before bed. Most people notice the wind-down before they notice the sleep.
Week one
Same time, same ritual. Magnesium and theanine work on the evening; the peptide works on the pattern.
Week four
The trial measured its results over eight weeks of nightly use. This is a habit, not a switch.
The evidence behind each ingredient.
- Magnesium contributes to a reduction of tiredness and fatigue.
- Magnesium contributes to normal psychological function and to the normal functioning of the nervous system.
- Magnesium contributes to normal muscle function.
How to take it
Take two capsules with water, 30–60 minutes before bed.
Make it part of the same wind-down each evening — the ritual matters as much as what's in it.
Asked often
Is there melatonin in it?
No. In the UK melatonin is a prescription-only medicine, not a supplement ingredient — and this doesn't work like melatonin anyway. It lowers cortisol so your body winds down on its own, rather than chemically switching you off.
When do I take it?
Two capsules, 30–60 minutes before bed. Consistency beats intensity — same time, same ritual.
What does the peptide do?
PeptiSleep® lowers cortisol, the hormone that keeps you alert when you're trying to switch off. Nuritas® found it by screening food proteins with AI for the fragments that do exactly that. In an 8-week randomised, placebo-controlled trial, the 250mg dose we use gave people 38 minutes more sleep a night and 13 minutes more deep sleep.
