The idea behind it
Better nights, says the brand, mean a better metabolism.
Renew is built around the idea that deep sleep underpins energy and weight. Here is the thinking in plain terms, with the brand's claims kept as the brand's claims.
Taken at night
One capsule with water 30 to 45 minutes before bed, according to the official directions.
Sleep-focused ingredients
Melatonin, L-theanine, ashwagandha and magnesium are among the most popular sleep and relaxation supplements.
Deep sleep and weight
The brand links poor deep sleep to weight gain and a slow metabolism — a connection supported by observational research.
Plant-based, per the brand
Described as non-GMO, vegetarian, soy-free and dairy-free, and non-habit-forming.
“Just take Renew before bed and let your body naturally do the rest while you sleep.”

What's inside
Eight ingredients, one capsule before bed.
The ingredients Renew lists on its official site. Individual amounts are not published.
- Best-researched
Melatonin
The hormone the body releases in darkness to signal night-time. It has the clearest independent evidence of the eight, particularly for jet lag and some sleep-timing problems.
- Relaxation
Ashwagandha and L-theanine
Ashwagandha (Withania somnifera) is an Ayurvedic herb used for stress and sleep; L-theanine is an amino acid from tea associated with relaxation.
- 5-HTP source
Griffonia simplicifolia
A West African plant that is a natural source of 5-HTP, which the body uses to make serotonin. It should not be combined with antidepressants without medical advice.
- Minerals & amino acids
Magnesium, zinc, arginine and lysine
Two essential minerals and two amino acids. The brand links them to sleep, immune function, blood flow and nightly regeneration.

Before you start
A few points worth checking before taking Renew:
- Antidepressants and 5-HTP. Griffonia simplicifolia supplies 5-HTP. Taking it with SSRIs, SNRIs, MAOIs, triptans or other serotonin-affecting medicines can be risky — ask your doctor first.
- Drowsiness. Melatonin and the other calming ingredients can cause next-morning grogginess. Do not drive after taking it, and avoid combining it with alcohol or sleep medicines.
- Ashwagandha. Avoid it in pregnancy, and ask your doctor if you have a thyroid condition, an autoimmune condition or liver problems.
- Sleep problems that need a doctor. Loud snoring, pauses in breathing at night or persistent insomnia should be checked professionally.
The evidence
What independent research says about sleep and the ingredients
We found no published clinical trial of Renew itself. The research below is about sleep and individual ingredients.
Melatonin has the strongest independent evidence of the eight. The NIH's National Center for Complementary and Integrative Health notes that melatonin may help with jet lag and with some sleep disorders, including falling asleep in people with delayed sleep timing, and that it appears safe for short-term use in most adults. Evidence for long-term use is more limited.
Ashwagandha and L-theanine have small trials suggesting benefits for stress and sleep quality, and magnesium is widely used for sleep with mixed evidence. 5-HTP, from Griffonia simplicifolia, has limited and inconsistent evidence. Arginine and lysine are amino acids found in everyday protein foods.
On weight, research consistently links short and poor-quality sleep with weight gain, which makes better sleep a sensible goal. But we found no evidence that any supplement burns fat during sleep. Treat the brand's claims about fat-burning and "turning back the clock" as marketing rather than tested results.
Good to know
What helps deep sleep day to day
Supplements work best alongside the habits with the strongest evidence for better sleep:
- Keep a regular schedule — go to bed and get up at the same times, even at weekends.
- Dim the lights and screens in the hour before bed.
- Cut caffeine after lunchtime and keep alcohol to a minimum, as both disturb deep sleep.
- Keep your bedroom cool, dark and quiet, and get daylight early in the day.
Simple routine
Getting started with Renew.
Take one capsule with a glass of water 30 to 45 minutes before bed, as the official site recommends.
Pair it with a regular bedtime and a screen-free wind-down so the habit supports your sleep.
Keep your bottles, even empty ones, in case you need the 60-day refund.

The details
Overview
Renew is a nightly capsule sold through its official website. The brand describes it as a "comprehensive nutritional formula designed to dramatically improve deep sleep, fat-burning and metabolism," built on the idea that the deepest phase of sleep affects energy, appearance and weight. The official site lists eight ingredients: Withania somnifera (ashwagandha), Griffonia simplicifolia, L-theanine, melatonin, zinc, magnesium, arginine and lysine. The amounts are not published. Each bottle is a 30-day supply, and the capsule is taken before bed. This page sets out what the official site states, how Renew is meant to be taken, and what independent research says about sleep and its ingredients. It is an editorial overview, not a hands-on test, and nothing here is medical advice.
How it works
Renew's pitch is that modern stress, screens and blue light disrupt deep sleep, and that poor deep sleep in turn makes weight harder to manage. Its formula is therefore built mostly from ingredients associated with relaxation and sleep: melatonin, the hormone that signals night-time to the body; L-theanine, an amino acid from tea; ashwagandha, an Ayurvedic herb; Griffonia simplicifolia, a plant source of 5-HTP; and the minerals magnesium and zinc. Arginine and lysine are amino acids the brand links to metabolism and nightly regeneration. The link between short or poor sleep and weight gain is supported by observational research, and melatonin has evidence for some sleep problems. But the brand does not publish trials of the finished capsule, and no supplement has been shown to burn fat while you sleep, so claims about fat-burning should be read as the brand's description.
Who it's for
Renew is marketed to adults who feel tired, struggle with sleep and find weight hard to manage. The brand says it is made from plant ingredients, is non-GMO, vegetarian, soy-free and dairy-free, easy to swallow and non-habit-forming, and is manufactured in the USA in a GMP-certified facility. It is not a substitute for medical care. Ongoing insomnia, loud snoring or pauses in breathing at night, or daytime sleepiness that affects driving or work should be checked by a doctor, as they can signal sleep apnoea or another condition. Griffonia simplicifolia supplies 5-HTP, which should not be combined with antidepressants or other serotonin-affecting medicines without medical advice.
Usage
The official site says to take Renew with a glass of water 30 to 45 minutes before bed, and recommends consistent use for 90 to 180 days. Because it contains melatonin and other calming ingredients, do not drive or operate machinery after taking it. Speak to your doctor first if you take medication — especially antidepressants or sleep medicines — are pregnant or nursing, or have a medical condition.
