Valerian as whole root
A 2020 review of 60 valerian studies concluded that whole valerian root gave more reliable results than extracts, whose quality varies.[1] Our valerian is whole root.
Clinical Studies: Peace, Love & ZZZs
The research behind Peace, Love & ZZZs
Guided by the science. Grown by nature.
Peace, Love & ZZZs is our melatonin-free sleep formula, made to support restful sleep and help settle a racing mind so bedtime feels calmer.* It pairs eight botanicals with two forms of magnesium. Two of those choices follow the research directly: valerian as whole root, beside the partner herbs its trials used most, and magnesium bisglycinate, the form a 2025 sleep trial tested.
Each study below is published and linked, with who took part, what they took, how much, for how long and what the researchers found.
Capsules, one serving (two capsules, once a day): 120 mg magnesium (60 mg as TRAACS® magnesium bisglycinate chelate buffered, 60 mg as magnesium oxide) · 100 mg chamomile · 100 mg holy basil (tulsi) · 100 mg hops flower · 100 mg jujube · 100 mg lemon balm · 100 mg magnolia bark 4:1 extract · 100 mg passion flower 4:1 extract · 100 mg valerian root. Melatonin-free.
Why it is built this way
Valerian with its partners
The same review found that valerian may work best alongside partner herbs. Hops was the partner used most often in the trials, then lemon balm, then passion flower.[1] All three are in this formula with the valerian.
Magnesium as bisglycinate
Magnesium bisglycinate is the form a 2025 Leibniz University Hannover trial tested in adults who reported poor sleep.[2] Our formula uses TRAACS® magnesium bisglycinate chelate.
What the studies found
Valerian first. In 2020, researchers from Chiba University in Japan and the University of Westminster in London reviewed 60 studies of valerian covering 6,894 people aged 7 to 80, with no severe adverse events reported.[1] In the four placebo-controlled trials of whole valerian root, sleep quality improved significantly compared with placebo (effect size 0.83, 95% confidence interval 0.03 to 1.62).
Passion flower
- Soonchunhyang University, South Korea, 2020: 110 adults with insomnia disorder took a passion flower extract or a placebo for two weeks. Measured overnight in a sleep lab, total sleep time rose 23.05 minutes from the start of the study on passion flower and stayed flat on placebo (−0.16 minutes, p = 0.049).[3]
Chamomile
- Shiraz University of Medical Sciences, 2024: a review of 10 clinical trials of chamomile with 772 adults. Pooled from five trials, scores on the Pittsburgh Sleep Quality Index, where lower is better, fell 1.88 points more with chamomile than in the control groups (95% confidence interval −3.46 to −0.31). Falling asleep improved in three of the four trials that tracked it, and staying asleep in two of three.[4]
What we say about Peace, Love & ZZZs: it supports restful sleep.*
Holy basil
- Clinical Research Australia and Murdoch University, 2022: 100 adults who had been stressed for more than a month and had sleep problems took 125 mg of a standardized holy basil extract twice a day, or a placebo, for eight weeks. Perceived Stress Scale scores and scores on a sleep-severity questionnaire improved more on holy basil than on placebo (p = 0.003 and p = 0.025). The sleep-questionnaire scores fell 48% from the start of the study on holy basil and 27% on placebo.[5]
- Disclosure: the extract's maker funded the trial and supplied the capsules.
What we say: it supports a healthy stress response and more restful nights.*
Magnesium
- Leibniz University Hannover, 2025: 155 healthy adults who reported poor sleep took 250 mg of magnesium a day as magnesium bisglycinate, or a placebo, for four weeks. Scores on a standard sleep questionnaire fell 3.9 points from the start of the study on magnesium and 2.3 points on placebo (p = 0.049).[2]
- Disclosure: the university funded the trial internally. One co-author runs a contract research firm that receives research funding from nutraceutical companies.
What we say: it supports your natural wind-down toward sleep.*
The other ingredients
Hops flower, 100 mg. Hops is valerian's traditional partner, and the partner used most often in the valerian trials reviewed above.[1]
Lemon balm, 100 mg. Lemon balm, a member of the mint family long steeped as an evening tea, is here for calm. It was the second most common partner herb in those valerian trials.[1]
Magnolia bark 4:1 extract, 100 mg. Magnolia bark is here on tradition, a mainstay of traditional Chinese herbal practice.
Jujube, 100 mg. Jujube has been prized in Traditional Chinese Medicine for over a millennium.
