Key Takeaways
- RevaSlim is a sleep-focused weight loss supplement that uses plant extracts and amino acids to support calmer nights and reduce late-night cravings.
- Ingredients like melatonin and lemon balm show credible support for deeper rest, reduced nighttime tension, and calmer evenings that may influence appetite patterns.
- GABA, passionflower, and L-tryptophan show limited evidence for body fat reduction or stronger metabolism support in current human research.
- Customer feedback comes from the official website and Trustpilot, with positive stories and complaints about weak results and refunds.
- Compared to Flawless Bloom’s KetoFuse, RevaSlim relies on sleep quality rather than metabolic drivers, so results may feel slower and less noticeable.
Introduction
Demand for metabolism-boosting weight loss supplements keeps rising as users look for natural products that support weight loss in a simple and steady way. Many users now prefer formulas made with natural ingredients that avoid harsh additives or strong stimulants.
Among the products in this space, RevaSlim has gained attention for its claim to support weight management through better sleep and a steady metabolism. The brand explains that RevaSlim uses plant extracts, amino acids, and sleep-support ingredients to help ease the mind, reduce late-night hunger, and support a balanced night cycle.
The idea is that deeper restful sleep may help the body use energy in a more steady way the next day. So many users want to see if this approach can support real progress toward a healthy weight.
But can RevaSlim deliver the support it promises? Does its formula offer real help for appetite control, steady rest, and fat loss without unwanted effects?
In this review, we will look at RevaSlim’s ingredients, safety, user experience, and value. We will also compare it to other metabolism-support supplements to understand its place in this category.
Ingredient Analysis – RevaSlim
RevaSlim Supplement Fact
We reviewed the ingredients in RevaSlim to see if they support the brand’s claims about better sleep, reduced hunger, and support for weight loss. The formula leans more toward relaxation and night support than direct metabolic action. Here is what we found.
Melatonin
We view Melatonin as one of the more reliable ingredients in this formula. A meta-analysis in Nutrition reported small but measurable improvements in body weight and waist size among adults with excess weight or metabolic concerns. These results match RevaSlim’s promise to support progress toward a healthy weight.
Another meta-analysis in PLOS ONE found that melatonin shortened the time needed to fall asleep and improved total sleep time in people with sleep problems. Better sleep can support appetite control, reduce overeating and late-night eating, and help steady daytime focus.
We approve of this ingredient.
Melatonin is a key ingredient in many supplements aimed at improving sleep, and it holds significant promise for individuals looking to enhance weight loss efforts by supporting better sleep patterns and controlling late-night cravings.

Lemon Balm Extract
We view Lemon Balm Extract (Melissa officinalis) as a helpful ingredient for users who deal with shallow sleep or stress. A randomized controlled trial published in the journal Clinical Nutrition ESPEN gave lemon balm to adults with mild anxiety and sleep trouble. After fifteen days, anxiety scores dropped, and insomnia symptoms improved.
A review in Nutrients described studies where lemon balm improved sleep quality, sleep duration, and restlessness. Many users also reported lower stress levels. Better sleep may help reduce late-night cravings and support weight loss routines.
We approve of this ingredient.

GABA
We see GABA added for its calming effect, but evidence remains limited. A systematic review published in the journal Frontiers in Neuroscience tested natural GABA in adults with insomnia and found only modest improvement in sleep time, along with some reports of headache and stomach discomfort.
A review in Frontiers in Neuroscience noted that oral GABA shows uncertain absorption and mixed results in human studies. These gaps make its impact on metabolism or hunger control unclear.
We disapprove of this ingredient.
Passionflower Extract
We see Passionflower Extract (Passiflora incarnata) included for relaxation support. A randomized placebo-controlled study published in International Clinical Psychopharmacology tested passionflower extract in adults with mild sleep issues and found only slight improvement in sleep scores, with no changes in weight or body fat.
Another study in Cureus looked at passionflower for anxiety and insomnia. Users reported some relief, but the sample size was small, and the study was short. No results showed support for fat use or appetite reduction.
We disapprove of this ingredient.
L-Tryptophan
We see L-Tryptophan used for its connection to serotonin and melatonin, but the results for weight are weak. A clinical trial in the International Journal of Obesity tested high-dose tryptophan in adults with obesity and found no extra weight loss compared to placebo.
A randomized controlled trial in the journal of Nutrition found that tryptophan can help with sleep onset and sleep quality at gram-level doses, but no studies showed steady reductions in body fat. RevaSlim positions it as part of a fat-loss formula, yet current data mostly support sleep rather than metabolism.
We disapprove of this ingredient.

RevaSlim vs Our Top-Rated Fat Burner (KetoFuse)
We Tried RevaSlim
We Tried RevaSlim
One of our reviewers used RevaSlim to see how it feels in real use. She wanted a dietary supplement that may support sleep, help her stay calm at night, and support weight goals without strong stimulants. She followed the steps on the product page and kept her routine simple.
She took two capsules each day with water, as stated. The capsules went down easily and caused no discomfort During the first few days, she noticed a gentle sense of calm before bed. She also felt less tense at night, and her sleep felt deeper on some nights.
After two weeks, she noticed a small drop in her urge to snack late at night. Her sleep remained steady, and her mornings felt calm for normal tasks. She did not see clear changes in weight, but she felt more in control of her habits.
She did not report strong side effects. She only felt slight stomach pressure once when she took the capsules without food, and the discomfort faded fast. No jittery feelings or headaches appeared during the test period.
She found RevaSlim easy to add to her schedule. Her results stayed modest, but she felt some support in sleep quality and nighttime comfort. She rated her experience 6 out of 10, stating it may help people who want mild sleep support and gentle appetite balance, not fast weight changes.
As an alternative, MetaboLife Ultra also claims to support weight loss, but does it really deliver on its promises? Many users are curious about its effectiveness and whether it lives up to the hype.

RevaSlim Side Effects & Safety
RevaSlim is presented as a product made with natural ingredients, soft plant extracts, and amino acids that aim to support sleep, calm the mind, and help users feel more in control of weight loss goals. The formula avoids harsh stimulants, so most healthy adults may find it easy to add to a simple night routine.
Reports from users show no major reactions. Some users mention mild stomach tension after taking capsules without water or food, and the feeling fades fast. These responses vary based on a person’s habits and how the product fits into their schedule.
The product page does not show a full supplement facts panel with exact amounts for each ingredient, so it is hard to judge the strength of the formula. Adults with medical conditions or those on daily medication should talk to a health professional before using RevaSlim to stay safe.
RevaSlim Real Customer Reviews
Customer feedback for RevaSlim appears on the official website and Trustpilot. The testimonials featured by the brand are highly positive, while Trustpilot provides less favorable impressions. The product does not appear on Amazon or the Better Business Bureau (BBB), so independent reviews remain limited.
A positive testimonial on the official website comes from Jessica, 46, New York, who stated:
I went from 189 to 133, and I no longer crave the junk food I used to eat all the time.
However, Trustpilot includes less favorable feedback. One reviewer, Sandra (AD), wrote:
I haven't lost any weight in 2 months; it's only a sleeping pill but very expensive. I contacted the company for a refund twice and got no answer.
These mixed reviews suggest that while some users report meaningful changes, others do not see similar results. With no broad third-party verification, it remains difficult to assess how consistently RevaSlim performs for most users.
Where to Find the Best Value
RevaSlim is sold only through its official website. The brand offers three purchase options:
- 1 Bottle (30-day supply) costs $69
- 3 Bottles (90-day supply) cost $59 per bottle
- 6 Bottles (180-day supply) cost $49 per bottle
Compared to other best metabolism boosting supplements, RevaSlim’s pricing falls within the mid-to-upper range. The website adds free U.S. shipping to all orders, and the multi-bottle bundles come with extra bonuses, so users get more value at lower per-bottle prices.
The 6-bottle option gives the strongest savings for people who want steady use. RevaSlim is not listed on Amazon, BBB, or other third-party stores, so the official website is the only place to buy it.
RevaSlim Pros and Cons
Pros:
- Includes ingredients that support relaxation and better sleep, such as melatonin and lemon balm.
- Simple once-a-day use that fits easily into most routines.
Cons
- Key ingredients such as GABA, passionflower, and L-tryptophan show limited support for metabolism or weight progress.
- Only a few independent reviews exist, and the product is not listed on Amazon or BBB.
- Some users report no weight changes and trouble reaching customer support.
- Sold only through the official website, so buyers have limited purchase options.
Should You Buy RevaSlim?
Reviews for RevaSlim appear on the official website and Trustpilot. The website highlights strong success stories, but Trustpilot includes critical feedback about results and customer service. With no presence on Amazon or BBB, it is hard to judge how well the product performs for most users. Some users describe better sleep and fewer late-night cravings, while others say they did not see progress.
Among its ingredients, melatonin and lemon balm show the most support in research. Both have data showing better sleep patterns and calmer nights. These effects may help users who struggle with late-night snacking or stress. The results still appear mild, but they match what the product aims to support.
The other ingredients, including GABA, passionflower, and L-tryptophan, have weak or inconsistent support for weight loss. Research shows that these ingredients may help with sleep or tension in some cases, but they do not show clear support for fat use or appetite reduction. This limits their strength in a supplement that claims to support steady weight changes.
Flawless Bloom Ketofuse uses a different approach. Its formula includes Raspberry Ketones, African Mango, Caffeine Anhydrous, Green tea extract , Apple Cider Vinegar Powder, Kelp, and Grape Seed Extract.
These ingredients support steady metabolism, appetite control, energy, and fat use. Users may find clearer support for daytime routines and steady progress since the formula focuses more on metabolic action.
RevaSlim may offer light support for users who want calmer nights and gentle help with late-night cravings. People who want stronger support for metabolism and daytime energy may see more promise in Flawless Bloom Ketofuse, since its ingredients focus on fat use, appetite balance, and steady energy.
