Pruvit is a trusted name in the industry, but that doesn’t mean their products will leave you lighter. Our team got into the ingredients and were taken aback by some of the customer comments on side effects. Furthermore, we dug into the scientific research and found that there’s a serious shortage out there backing up exogenous ketones. So here we are, all of the information we found sprawled out in front of you, begging the question: Does this fat burner really work?

Pruvit Readers: Click here to find out why we're giving away samples of our product, Burn HD.

What is Pruvit?

First of all, Pruvit is a line of powdered weight-loss drinks aimed at eliminating fat. In our quest for discovering the possible culprit for the potential side effects, we lined up the suspects:

  • MCT powder
  • Beta-hydroxybutyrate
  • Malic acid
  • Caffeine
  • Stevia

Supposedly, these supplements suppress appetite, encourage fat loss, boost energy levels and increase strength. Add one packet to 12-16 ounces of cold water and drink with or without food.

Pruvit was first introduced in 2012. The product is available directly from the official website, and can also be purchased on Amazon. They do have a research tab on their website, but it doesn’t exactly tell you much, and certainly doesn’t take you to any studies carried out on their products…

Are Pruvit Keto Side Effects an Issue?

The first concern we have is Pruvit Keto side effects. “As with any supplement, there may be a chance dieters experience adverse reactions,” said our Research Editor. “This is a rarity, but something that shouldn’t be overlooked.”

One customer stated, “Good taste, but I took 1/2 a packet and 15 hours later I still felt wired.”

But, not all users experienced Pruvit Keto side effects.

One person said, “Seems okay so far. Not convinced it does much though.”

“No bad effects. But not seeing any weight-loss with this stuff,” revealed another person.

Pruvit Weight-Loss – “Are You Seeing Results?”

According to user reviews, some didn’t notice results from Pruvit weight-loss supplements. “Did not decrease my weight,” said a customer.

“Slow results, but I still lost a few pounds,” commented another.

Then again, there are users that noticed solid results.

“It gives you a slight boost,” reported a consumer.

“I use it before workouts. Helps with energy,” said a user.

Our research shows that minimal results or issues with side effects are enough to ruin a dieters chance at success. If Pruvit weight-loss is not what users are seeing, why would they keep using the products?

Pruvit Results – “Is the Diet Plan Effective?”

Digging through the official website, we found research supporting the claims of Pruvit results. Caffeine is one of the active ingredients, and there are studies showing it helps boost metabolic rate; possibly promoting weight-loss. There’s also solid science backing the effectiveness of amino acids and muscle strength and recovery.

The Bottom Line – Does Pruvit Work?

Is Pruvit weight-loss really a thing? Well, there’s a chance you’ll notice results. We like that there’s research supporting some of the ingredients and some decent reviews, but we’d like to see some research into the complete Pruvit diet plan.

If you’d like to lose those extra pounds, we suggest a supplement containing ingredients backed by research and supported by positive comments.

Among the best products we’ve seen this year is one called Dietspotlight Burn. The four clinically-tested ingredients shown in human research to help jump-start metabolism, get that fat loss moving and beat hunger. User testimonials all over the web talk about just that, and more.

Plus, the company behind Dietspotlight Burn supports the formula and it’s effectiveness 100%, so they’re offering a Special Trial Offer.

What is Pruvit Keto OS?

Pruvit Keto OS is a ketone supplement that aims to promote and maintain ketosis.

Pruvit Ingredients

Pruvit sells Keto OS products. The formulas are supposed to help you reach a more "natural" state where your body burns fat for fuel. This is the same idea behind a low-carbohydrate diet like Atkins or the original South Beach. In order for the product to work, you have to change your diet.

Pruvit Ingredients and Supplement Facts

Serving Size: 1 Packet
Serving Per Container: Not Listed
Amount per Serving% DV
MCT Powder**
Beta Hydroxybutyrate**
Caffeine (Charged Only)**

Other Ingredients: Natural flavor, stevia, malic acid

We dug into the Pruvit ingredients to give you the details you need.

MCT Powder

MCT Powder, also known as Medium-chain triglyceride is a component of human, vegetable, and plant body fat.

What is it Supposed to Do?

MCT is used to reduce seizures in children and help control weight-loss in people with AIDS.

Clinical Research

Though there aren’t many studies done on the relationship between MCT and weight-loss, there was a study completed that related MCT to sustaining/gaining weight. In the Journal of Clinical Biochemistry and Nutrition, there was a study done to see if MCT (Medium-chain triglycerides) decreased weight-loss in elderly people with PEM (protein-energy malnutrition). The study said, “Fed a low protein diet, serum albumin concentration in the MCT group was significantly higher than in the LCT group, suggesting that MCT intake has a preventive effect on PEM.”

Beta Hydroxybutyrate

Beta Hydroxybutyrate is an acid found in organs such as the heart, liver, and brain that increases while exercising, fasting, or dieting and acts as a histone deacetylase inhibitor.

What is it Supposed to Do?

Beta Hydroxybutyrate is used to help control weight-loss, help decrease pain for people with fibromyalgia, and treat muscle loss for people with narcolepsy.

Clinical Research

Based on a study completed in the International Journal of Environmental Research and Public Health, Beta Hydroxybutyrate (in this study, Beta Hydroxybutyrate is in the Ketogenic Diet) does promote weight-loss. The study said, “A period of low carbohydrate ketogenic diet may help to control hunger and may improve fat oxidative metabolism and therefore reduce body weight.”


Caffeine is a stimulant that is added to products such as coffee and sodas to increase energy. It is also found in natural growing foods such as nuts, seeds, and leaves.

What is it Supposed to Do?

Caffeine is used to control headaches, increase mental alertness and help promote weight-loss.

Clinical Research

It is proven that caffeine promotes weight-loss. Based on a study done in 2005 by the Department of Human Biology at Maastricht University, “High caffeine consumers reduced weight, fat mass, and waist circumference more than low caffeine consumers; resting energy expenditure was reduced less and respiratory quotient was reduced more during weight loss” They also continue by saying, “High caffeine intake was associated with weight loss through thermogenesis and fat oxidation and with suppressed leptin in women.”

Malic Acid

Malic acid is an acid produced by living organisms that creates the sour taste of foods.

What is it Supposed to Do?

Malic Acid may be used to decrease tiredness. [2]

Natural Flavor

Natural Flavor is the flavoring of foods and drinks.

What is it Supposed to Do?

There is no relationship connecting Natural Flavor and weight-loss.

One that we’re keeping our eye on is one called Dietspotlight Burn. To learn more about the clinically-tested ingredients, click above.

Pruvit Scientific Abstracts

MCT Powder

31 participants had finished the study (body mass index (BMI): 29.8 ± 0.4, in kg/m2). MCT ingestion had resulted in decreased endpoint body weight as compared to olive oil (−1.67 ± 0.67 kg, unadjusted P = 0.013). There had been experience of more loss of fat mass (P = 0.071) as well as trunk fat mass (P = 0.10) with MCT ingestion than with the olive oil. Trunk fat mass, intraabdominal adipose tissue and total fat mass were all decreased with MCT intake as opposed to olive oil ingestion (all unadjusted P values < 0.05). It was concluded that consuming MCT during a weight-loss plan had beneficial effects on weight-loss when compared to the olive oil, thus making it a candidate for a successful addition to a weight-loss diet. [1]


Weight mass as well as body mass of the subjects were reduced significantly (P<0.0001). Levels of total cholesterol reduced from the 1st week to the 24th week.HDL cholesterol had been greatly elevated and LDL cholesterol levels had been greatly reduced following treatment. Triglyceride levels had reduced greatly after 24 week treatment period. Blood glucose levels had decreased significantly. The study had displayed the helpful effects of a ketogenic diet in the long-term. It greatly decreased body mass index and body weight of the subjects. It also reduced triglycerides levels and LDL cholesterol as well as blood glucose. It had in turn increased HDL cholesterol levels. Ketogenic diets for a longer duration of time had not displayed any significant side effects in subjects. The study had confirmed the safety of a ketogenic diet for periods of time in which were longer than had previously been reported. [2]


Caffeine could work with other drugs like ephedrine as well as anti-inflammatory agents. It seems male and female athletes contain similar caffeine pharmacokinetics. For a given dose of caffeine, absolute plasma concentrations and the time course as well as metabolites are all similar. Exercise or dehydration does not have effects on caffeine pharmacokinetics. The information regarding the subject is limited, indicating that those who use caffeine and who do not use caffeine had responded in the same fashion, and caffeine withdrawal may not hold any importance. Caffeine may partly effect a more favorable intracellular ionic environment within muscles that are active. [3]

Individuals who intake large amounts of caffeine had experienced weight-loss through thermogenesis and fat oxidation, while individuals who consumed low amounts of caffeine regularly had experienced weight management improvement partly via fat oxidation and thermogenesis. [4]

  •  This Works - but do the research before jumping in
    JBurrus (Verified User)

    I have been using Pruvit for over a month now but am using it in conjunction with a true Ketosis diet. The objective for me is to control inflamation in the body and thus my immune system as I have an autoimmune disease.
    I have had numerous people tell me that I’ve lost fat even though I didn’t need to lose any. I use the urine monitoring process to be sure I’m not going into a state of ketoacidosis. If you are going to use Pruvit for anything, you must monitor and change your diet because you are adding ketones that require fat to burn out of your system.
    Do the research and follow what the experts say. My immune system is functioning better. Yes it takes about 3 weeks for your body to adapt to the change, but it will.

    • Summer (Editor)

      Hello JBurrus. If you’re on a ketosis diet your urine strips will appear light to dark magenta (for most brands). If you are in ketoacidosis, the same thing will happen. Unless the strips don’t change color at all, there’s no way to determine if the ketones present are as a result of the lower carb diet or ketoacidosis.

      According to the experts at Healthline, ketosis is a mild form of ketoacidosis.

  • Rmendel

    Can you take dietspotlight burn with the pruv it?

    • Summer (Editor)

      Pruvit is the company. Can you tell us what product you’re wanting to take with Dietspotlight Burn?

  • When nothing else would work, Pruvit did
    mike (Verified User)

    seemed like i have tried every diet. Could not stop my carb cravings. Keto OS is a the ONLY thing that has worked for me. Keto is perfect way for me to eat and Keto OS was the on ramp that got me to Keto eating. i have lost 22 pounds and 4 1/2 inches in my waiste. I don’t have any brain fog at all. The 2:00 blues are totally gone. at first it did cause me to go to the bathroom a lot but then it was like my body got used to it. i still do occassionly when i drink it. Would not trade this experience for anything! I am hate to hear that it hasn’t worked for EVERYONE. I guess some bodies it does and some it doesn’t. I could not stop eating carbs. Cinnamin rolls, pasta, bread…I was helpless. For the last 3 months that i have been taking this, i have NO CRAVINGS! And work out better than i have ever.

  • Jen

    I can’t speak for anyone else nor would I try to, I have been on Pruvits Max since Jan and the product has done everything they claim it does, what might work for me may not work for others, love the drink and couldn’t be happier with my results! Whereas others may lose weight I have gained muscle, I like the fact that it’s all natural and tastes good! I am overweight and the drink has helped me with inflammation I actually have gone down from a 16 to a 13 and still have a ways to go, I’m not tired and the caffeine in the drink doesn’t give me jitters! I haven’t had brain fog since!

  • Patricia Clark

    Started off with 1/2 packet of the Keto/OS chocolate drink with food. Two days, no problems. On the third day, I drank 1 whole packet with food. Had some diarrhea& stomach pain later in evening, but I attributed that to eating a sugar-free ice cream bar with maltitol. Fourth day I drank 1 whole packet in between meals, as I had read on a blog was ok to do. Later in evening more diarrhea/stomach pain. Fifth day, back to 1/2 packet with food; evening – more diarrhea/stomach pain. I might mention that I also took digestive enzymes after two meals on these days. I also am an older person without a gallbladder. Has anyone else experienced this? Should I continue with drinking smaller amounts with food and just wait to adjust? Should I be drinking some of the other formulations (orange drink, keto kreme) as well?

    • Rachel d Johnson

      So it is doing the same to me. The stomach pain is so intense, I am a diabetic and have had diarrhea for almost a week, I did stop using the product 4 days ago and the pain in still there how long before it gets out of my system.

    • Trevor Folgering


      This is due to the MCT powder found in Prüvit. Your body needs to adapt if you are having these side effects.

      You may want to try half a packet in that morning and half in the afternoon.

      Also you mentioned you have no gallbladder. The gallbladder releases bile to help break down Fat. This is why you may be experiencing high bouts of diarrhea, as your body may lack that bile to breakdown fats efficiently.

    • LadyDi4613

      This product also caused severe diarreah for me and I do not have a gallbladder, There is no way my body will accept it, I certainly think that Ptuvit needs to know it’s not for everyone and more information should be given out. It’s such a high cost product and a waste of hard earned money if it doesn’t work for people who don’t have a gallbladder!!!

    • Summer (Editor)

      We’d love to help Patricia. What Pruvit product did you use?

    • East Coaster

      If you drink your Keto/os slowly over 1 hour you will notice less GI upset. I was drinking it fast and would be in the bathroom, but, when I drink it slowly over 45 minutes to 1 hour I experience no GI upset at all. I’m 40 with no gallbladder

    • seib

      It is also recommended that you drink it without food, wait 30 min or until you are hungry – then eat

    • KKP

      I am 52 looking to start a business with Prutiv. I have no gallbladder and I have diarrhea every day. It’s normal for me! I had a gastric sleeve done and have no energy. I lost 65 with the surgery 4 years later I gained 25 back. I CRAVE sugar and carbs so hoping this will help! But I think everyone that doesn’t have a gallbladder has problems. Everyone I have talked to does!

    • Loreli

      When your body is adapting to Ketones, you will get what is called a keto flu. The best way to have this happen once (may be over some days but not over and over again) is to eat the keto diet as well so you become fat adapt and not have your body relying on carbs for energy. Far healthier for your body.

  • Lauren

    This product is phenomenal! I actually take two a day. I have experienced the jitters before, so I prefer the caffeine free version, which is as easy as selecting it. With the caffeine free version, Pruvit gives me clean, naturally energy.

    • Victoria (Editor)

      Hi Lauren! That’s great to hear. Another product that offers a caffeine-free version is Dietspotlight Burn.

  • Jane

    I had reach a plateau after several months of eating a low carb higher lean protein diet. I started taking Pruvit and I started loosing weight again and after taking it for 4 weeks I’d drop down a size in my pants. I felt a little jittery from the Charge formula so I switched to the non-caffeine formula and haven’t had anymore jitters.

  • Pruvit OS
    Babs (Verified User)

    Pruvit OS is not a weight loss product.

  • Stacey

    Taste horrible makes me gag. No change in anything very disappointed

    • Summer (Editor)

      Don’t be discouraged Stacey. You can get your body into ketosis while eating foods that taste great. Programs like Atkins and the old South Beach work with menus consisting of fewer carbohydrates to get your body burning fat.

    • Cory

      I have same after 1 month 0 change and very terrible taste except for the chocolate swirl

  • S Hale

    Does not curb appetite. Gives me headaches and constipation. Very pricey.

    • linda bell

      You are very correct

  • Slim

    i love the product – felt great when taking and was able to control what I ate. Only bad thing is it causes a yeast infection after about 10 days of the product. Tried again taking it and same prob after about 10 days.

    • Lauren

      That is surprising since there are no sugar or carbs in the product, and nothing that yeast would be able to feed on. I wonder if it is causing your body to cleanse the yeast out? Just a thought! I am actually taking this product to help me get rid of candida (yeast).

      • Jane

        Candida loves to eat breakdown products of glucose, which include any and all sweeteners. This is exactly why you are getting yeast infections.

      • Adair vilella

        Sugar alcohols and the Maksic acid could def cause yeast. It wreaks your gut. Not surprising at all

    • Summer (Editor)

      Did your doctor directly connect the Pruvit product you were taking and the yeast infection?

  • Adair vilella

    This product is awful. The sodium made me blow up! It wreaked havoc on my gut. I gained weight and body when I was actually working out more and not drinking or eating sugar. False claims. Made my body super acidic and bloated! I gained 16 pounds half of which came on fast in the last few weeks and has to be water. I have been off it for a week, was on it three months and I want my money back.

    • linda bell

      They are out of Louisville Ky in Norton Commons you should get your money back!

    • ronna


    • Loreli

      Gaining weight while working out more….muscle?? It does weigh more then fat. Was your diet 100% good? If you’re working out more…..that can cause gas and bloating…..so I wouldnt be convinced its the products. Hard to determine when your making multiple changes.

    • Muriel Myers

      She might be experiencing the water wash thing
      Where fat cells like to retain their shape so when fat burns water washes in, then it washes out at about two weeks
