ProvaSlim Review: A Detailed Look
ProvaSlim is a powdered nutritional supplement whose seller claims can aid in weight loss along with a host of other benefits.
Among the advertising for ProvaSlim is a video intended to appeal to people who have struggled with weight issues. The advertisement claims to finally have a solution for them that’s easy and effective.
Below we take a closer look at ProvaSlim’s ingredients, advertised health claims, and help you decide if it's worth buying.
We have reviewed many weight loss and “metabolism boosting” supplements and have a unique perspective on how they’re marketed and what they really offer.
How Does ProvaSlim Work?
Putting aside the flashy marketing campaign and convoluted origin story presented in the video, the seller makes the case that leptin resistance is the underlying reason for many people’s struggles with weight loss.
What is Leptin?
The hormone leptin plays a critical role in the long term regulation of the body's signaling for food intake and energy expenditure. [1]
Leptin is released from adipose (fat) tissue and communicates to your brain that the body has enough stored fat.
Thus it controls overeating by regulating the hunger response, among other functions such as signaling for regular calorie use.
On the other hand, when leptin levels are low your brain responds with hunger and a slowing of the metabolism to preserve calories. [2]
This cycle is constantly running to maintain a healthy bodyweight. However, certain lifestyle and genetic factors can disturb this homeostasis and cause leptin resistance.
Leptin Resistance and Obesity
Leptin levels in the body are relative to how much fatty tissue a person has. So a person with more body fat will have more leptin in their blood.
The danger of this is that over time the body will become less sensitive to Leptin signaling. [3]
Developing Leptin resistance will unleash a negative feedback loop that leads to more weight gain.
Even though the body has plenty of fat tissue the brain no longer responds to the hormone to signal satiety, leading to overeating and even more weight gain.
Even worse, once your body is not processing Leptin levels correctly it can also signal for decreasing metabolism, resulting in a state of caloric preservation. [4]
ProvaSlim Ingredients
The sellers of ProvaSlim claim that their formula can:
- Target leptin resistance
- Restore gut health
- And activate your metabolism
The key ingredients in the supplement include the following
- Inulin
- Green tea extract/EGCG
- Shilajit
- Acai berry
- African mango
- Pomegranate
- Grape seed
- Cinnamon
- Ginger/beetroot
- Probiotics - 9 strains
The seller of ProvaSlim believes that this formula provides a multifaceted solution to reset the hormonal imbalance caused by leptin resistance and aid with weight loss.
Scientific Support for Claims
Inulin - a prebiotic fiber that has a number of benefits for digestion and gut health. One of its main roles is to feed the good bacteria residing in the colon.
As a soluble fiber when it mixes with liquid in the stomach it becomes gelatinous which can provide a feeling of fullness and slow digestion. [5]
EGCG - an antioxidant found in green tea, may have some positive effects on weight loss and metabolism.
Several studies have found that green tea extract can increase fat burning when taken before exercise and when at rest. [6] [7] [8]
Additional studies have found that it may also boost metabolism and help with weight loss. [9]
Shilajit - Use of this substance has its roots in Ayurvedic medicine where it was used to treat conditions related to Altitude sickness and other ailments.
It is regarded for its supposed anti-inflammatory and antioxidant properties. [10]
Probiotics - Supplementing with Probiotics may have a positive influence on your gut microbiome which in turn can have a range of benefits.
There are many studies linking poor gut health with obesity, and studies that have shown leaner people having different and more diverse gut biomes than obese individuals. [11]|
Some strains of probiotics have also shown to have an effect on fat loss. [12]
PolyPhenols/Antioxidants - Acai berry, Pomegranate, and grape seed are high in Polyphenols which have a number of health benefits. However, when it comes to weight loss there is limited evidence for benefit.
One study on Grape Seed Extract concluded, “However, whether GSPE can reduce body weight is still controversial.”
Another study titled, “Dietary Polyphenols and Obesity” concluded that, “At present, there is not sufficient data to support recommending long-term, safe usage of these polyphenols for prevention and treatment of obesity.”
Overall the ingredients selected for ProvaSlim have moderate scientific support for use in a weight loss supplement. Some may have positive effects on inflammation, metabolism support, and appetite suppression.
However, none are recognized as current treatments for leptin resistance.
ProvaSlim Red Flags
The creators of this product use a common supplement marketing strategy that’s highly effective but that we don't consider ethical.
Examples of this include:
- A prolonged video ad that you can’t fast forward
- Claims to reveal simple “10 second morning ritual” for fat loss
- Say that doctors won't tell you about it and weight loss industry hiding it from you
- Make you feel like the problem is not your fault
- Repetition
- Reveal “secret” ingredients from exotic places where people are healthier and live longer…
In addition to these over-the-top marketing and psychological tricks the ad for ProvaSlim also
- Encourages bulk order on implied threats of future limited supply
- Doesn't show the ingredient label
- Falsely claims to have a 5 star rating from 100k reviews on Trustpilot
Finally, the only physical address provided on the ProvaSlim website belongs to a warehouse for a company called Jetpack Shipping.
This is an order fulfillment center that also provides private label supplements.
This means that virtually anyone from anywhere can use this company to start a supplement brand like ProvaSlim.
Since nutritional supplements are not as closely monitored by regulatory agencies as pharmaceuticals (for example), a lot of the issue comes down to trust of the seller and their brand.
The seller of ProvaSlim gives no indication that they are a trustworthy company. In fact there are red flags regarding the seller that signify the opposite.

The Bottom Line
It’s tempting to believe that obesity is the fault of a misfiring hormone that can be corrected just by taking a supplement.
However, current research suggests that the most helpful actions to take against leptin resistance are diet and lifestyle changes that include:
- Changing your diet to limit or avoid sugars, refined carbs, and inflammatory processed foods [15]
- Regular Exercise [16]
- Improve sleep [17]
Some experts have come up with leptin resistance diet plans which are variations on popular low carb/paleo/keto diets.
These favor vegetables, healthy fats, and quality proteins over processed carb heavy foods and include an eating schedule with less snacking and more time between meals.
We would recommend trying these lifestyle changes first, before spending money on any questionable supplements.
