Comparing Perfect Keto and Keto//OS

Exogenous ketones are becoming an extremely popular supplement for performance. They are brand new to the mainstream market so it makes perfect sense that there are a lot of questions about what’s important in a ketone product so that buyers can make an informed decision. This is the guide to compare Perfect Keto Base vs. Pruvit Keto//OS ketone products.

Marketing and advertising claims can leave consumers feeling bewildered on what’s important and what is “healthy.” As with any purchase, it’s important to take a look at what it has to offer and make the best choice for your goals.  Our aim is to keep it simple and break down the few significant differences and why they matter.

There are three general categories of ketone supplements (perhaps four if you include products that use the term “keto” but don’t do anything for ketosis).

Perfect Keto and Keto//OS are ketone salts. Important questions to ask when looking at ketone supplements are:

Do they contain ketones? (Re: Raspberry ketones)
Do they promote ketosis?
Do they have artificial ingredients and fillers?
Are there ingredients that I am intolerant of? (eg. soy, dairy, gluten)

Let’s take a quick overview of the Perfect Keto and Pruvit ketone products, then dive in deeper to ingredients, product development, and price.

Perfect Keto vs. Pruvit Keto//OS – Product Overview

Keto//OS Overview

The Keto//OS products are made by Pruvit and come in four different types:

Keto//OS Max Maui Punch
Keto//OS Max Swiss Cacao
Keto//OS 3.0 Chocolate Swirl
Keto//OS 2.1 Orange Dream

Option for each: buying products “charged” (with added caffeine) or caffeine free.

Perfect Keto Base Overview

Perfect Keto Base comes in two flavors:

Chocolate Sea Salt
Peaches and Cream

Let’s dive into more the details of each – what they are, and how they’re made, and how to buy them.

Perfect Keto vs. Keto//OS Ingredients

The first place to start, and perhaps the most obvious differences, are in the ingredients.

Keto//OS Ingredients

The most important ingredient in an exogenous ketone supplement is beta-hydroxybutyrate (BHB). In Keto//OS, the BHB content is described as part of their proprietary blend, so the exact amount is unknown to the consumer. Other ingredients include:

Carbohydrates (3-5 grams per serving, depending on which Keto//OS product)
Inulin and xanthan gum (fillers)
Erythritol (4 grams of sugar alcohols)
Caffeine (optional)
Dairy (in the Orange Dream flavor)

Notes on Caffeine

Caffeine is awesome. It’s a great tool for mental alertness and for being a productivity beast. It makes us feel stimulated by occupying adenosine receptors in the brain. So essentially it blocks the “tired” molecules from getting to us. Make no mistake though, caffeine is not actually usable energy. Ketones are molecules that actually deliver energy, so it’s important not to confuse feelings of stimulation with real energy.

Notes on Carbohydrates

On the classical ketogenic diet, carbohydrates are limited to less than 30-40 grams per day to trigger the body into a metabolic state of ketosis where it is mobilizing fats as its primary source of energy. Small amounts like 3-5 grams of carbs isn’t going to kick you out of ketosis but it’s worth considering if you want to allot some of your carb quota to your ketone supplement or spend it elsewhere.

Carbohydrates in the form of sugar alcohols are not considered “impact carbs” but they aren’t the greatest for the GI system.

Perfect Keto Ingredients

  • We use only high-quality beta-hydroxybutyrate (BHB) salts in Perfect Keto. Each serving comes with 11.3 grams of high-quality BHB.
  • Each tub contains 211 grams of product, good enough for 15 full-scoop servings, or 30 half-scoop servings.
  • Other ingredients: Magnesium, Potassium, Cocoa, Stevia leaf, Vitamin C

Product Development

Perfect Keto’s founder is Dr. Anthony Gustin. Dr. Gustin a functional medicine clinician who follows a low-carb/ketogenic diet and is open about his own experiences with ketosis and nutrition in general. He developed the product, picking each ingredient in specific amounts to provide maximum efficacy.

Notes on GI Distress

One of the biggest complaints people have about exogenous ketones is high GI distress. Perfect Keto uses salt splits specifically to minimize GI distress from beta-hydroxybutyrate.

Perfect Keto uses the highest quality BHB ketones, sourced right in the USA and blended in the best way for minimizing GI problems.

Perfect Keto vs. Keto//OS Buying Process

Keto//OS Buying Process

In order to purchase Keto//OS products, you have to be referred by someone and enter their “Referrer Code” before checking out. That’s because they use a Multi-Level Marketing (MLM) structure.

Perfect Keto Buying Process

Perfect Keto’s buying process is similar to most retail we are all familiar with: you simply make your purchase. No MLM or membership requirement. We want ketosis and exogenous ketones to be accessible to anyone, easily. No strings attached.

Ketone Supplement Summary

Within the last few years, ketone supplements have become a popular way to support those following a ketogenic diet and striving to maintain a healthy level of ketosis as much as possible. However, a lot of people still don’t really know about the different types of ketone supplements out there and how they can be beneficial for when you go keto.

Understanding ketone supplementation is important because you want to make sure you’re getting the most bang for your buck and avoiding any products that don’t do what they claim.

Ketone supplements are a fantastic tool for maximizing a low-carb ketogenic. Perfect Keto doesn’t have any interest in endorsing or condoning the supplement industry or specific products, but we certainly encourage educating yourself on what you’re purchasing and how it will align with your goals. See our guide on the Different Types of Ketone Supplements for a high level view of the industry.

As always, we are advocates of the scientific method, test and retest! We hope this is helpful as you research what’s available out there! 🙂

    1. Thank you for the comparison of the two products, I much prefer not having to deal with a mlm group. I always feel someone is getting ripped off and it’s usually me.

  1. How do people afford a 30 serving jar of powder [ replacing a meal ] meaning one use per day for one month at $85 for one person only ?
    That is a “STARBUCKS” coffee price for the poor who need this perhaps the most with low income can not provide all the fancy new Keto products, sweeteners, etc. Why is a powder costing so much and how will anyone maintain it at this price ? And this is just one product and flavor, and to work it as a business is $400 to $1,300 for products. This is to be a “life change” which a purchased product that cost money each month to maintain is not a natural source of anything. Plants, meats, and veggies and fruits are natural and can be grown, not something from a manufacturer. It seems our society wants to make money more then creating a healthy world of people free of diabetes and other illnesses. I feel very frustrated with it all.

    1. I don’t really get your point, nor do I appreciate your judgment. We dedicate all of the revenue we get from these products to help try to bring the price down and make ketosis more accessible. It is not free to put out all of this information, hire staff, manufacture, ship, have customer service, do R&D, etc. etc. etc. etc. etc. Businesses need to bring in revenue to do things and solve problems. We are trying to help people solve their health problems. Of course I think eating real food is the better solution, but many people aren’t convinced of that yet. If you have a better way to solve the food problem in this country, please let us know instead of being critical of us trying to help others.

      1. I have been taking a keto product from GNC. I do really like it. But just curious how this compares. I also follow keto woe and I love that. The Keto just gives me extra energy as you say, although some could be from guarana.I have to look up the exact name when I get home. It is BHB salts.

  2. Thank you. I didn’t know what to ask in relation to the two products and you looked like you’ve covered everything I would have asked! I know what my choice is now!

  3. I left Pruvit after 5 weeks! The MLM was ridiculous and the product was not working for me! Finding Pk has been a blessing! Thank you Dr Anthony

    1. I agree. I also left pruvit. It was way to expensive and i could not afford it after 2 months. It did nothing for me as far as weight loss goes. The mlm was driving me nuts too. I am glad i saw this product and read this post. Thank you. I will be giving this a try.

      1. I’m also a Pruvit customers and love the effects. I just can’t afford it. I’ve been reviewing and will be trying Perfect Keto

  4. The Orange Dream flavor of Keto OS is the only one with 110 calories per serving, and that’s because that particular flavor includes MCT oils.

  5. I’ve tried both and I have now ordered my third container of Perfect Keto. There is no comparison. Love it!

  6. Can you get perfect keto with caffeine if you want to? I am so over paying out the kazoo for Pruvit ~ I tried to stop auto draft/order and they still sent me more product and charged my account $141 AGAIN !! Help !!

      1. I put the new coffee flavor of Perfect Keto in my morning coffee! It is amazing! That gets me some caffeine and my ketones??

    1. Apparently you did not learn how to change your smartship. I can change mine and it not charge me whenever I want. I also get free product each month. Sorry you had a bad experience. It’s got me 50 lbs lighter. I’m loving it still since march.

  7. I have tried the apricot 5 day sample pack. How do portion sizes compare with your product? I’m trying to figure out how much to order. I currently use one packet of apricot per day. Is this equivalent to a half or full scoop of your product? Thank you!!

  8. You may need to update this article with the new, improved formulas of Keto//OS so we can have a better, true comparison of the products. There is clear bias, understandably, in your reviews and articles which is rather frustrating.

  9. I gotta say, Perfect Keto is awesome at providing useful and clear content. All of my research has been answered somewhere here, and then some. Compared to the watered-down info videos found at Pruvit, the info found here is awesome! Quality information leads to educated customers, which leads to sales.

  10. The information was very helpful…..I will get the PerfectKeto, and after a month I will write a truthful update.

  11. Does this product provide a level of ketosis without restricting dietary carbs completely? As I understand, KETO OS claims that their product puts you into ketosis without the necessity of adjusting your diet, though it is recommended. I look forward to trying your product!

    1. You cannot eat whatever you want and stay in ketosis. To stay in ketosis you need to do the Keto eating lifestyle. If you eat a doughnut it will kick you out of ketosis.

  12. Your pricing is off a bit. You sell MCT as a separate product, while this is included in the Pruvit Keto//OS. Also, your prices state that Keto//OS is $130 for 20 servings when it is actually $144 for 30 servings which is $4.80 per serving or less than $1.00 more than Perfect Keto (Most of the time Pruvit has a 20% off sale, so it is even cheaper). Also, remember that MCT is included in the Pruvit product and is another product with Perfect Keto. I’m comparing the charged Orange Dream Keto//OS, because that is what I use and it has the added (or not added) caffeine.

    I was comparing because I thought I could save a lot with Perfect Keto, but this doesn’t appear to be the case.

  13. I am one to try before I give my honest opinion, whether it’s MLM or not. Did try the MLM product 4 different times and my body continued to reject it….bloated feeling was extremely uncomfortable for days but they continued to tell me my body needed to adjust to it meanwhile I looked and felt like a BLOWFISH !!! I finally gave up….not bad mouthing the other, unfortunately it did not work for me. I will be ordering PKeto to try just wanted to know what is your return policy???
    THANK YOU IN ADVANCE

    1. Hello Irma, sorry to hear of your experience with our product. If you ordered through shop.perfectketo.com, please email [email protected], and our customer service team will walk you through the refund process. Again, our sincere apologies the product did not work for you. We will do our best to make it right.

  14. I am curious. After using a keto supplement a ketostix turns dark purple. I never reached that level on diet alone. Is it true ketosis or excreting the keto supplement? Love to know

  15. I’ve tried a few keto products and they are all fizzy and very sour (like sweettarts powder. Why is this? Is your Peaches and cream sour? I tried Pruvit with both the Max Caffeine and Orange Dream. The Orange Dream was really good. Not sour, but sort of creamy (because it has the dairy). I just don’t want to waste money on sour.

  16. Any suggestions on what drinks don’t contain sugar when I think they all do except for water.
    If I want coffe that means that I would not be able to add half and half cause it contains sugar?

    1. Hey Sandra, you can try coffee with heavy cream, mct oil powder, butter, coconut oil, or anything that has minimal carbs. Other sugar free drinks include unsweetened tea, matcha, sparking water (Lacroix is a great brand).

  17. I have purchased the Keto OS before and now having tried Perfect Keto will never go back. That stuff is over priced and if you join any keto group on fb you can’t escape someone trying to sell it to you. Perfect Keto has really helped me and I love what the company stands for. If you listen to Anthony on podcasts you can tell his heart is in this product. Can’t wait to see this company grow and happy to be a lifelong supporter!

  18. Can you please tell me if you are supposed to use BOTH the keto base and the keto MCT powder? There are two products, and i’m still new to this and wondering if i take them both or one or the other? Please help lol

    1. There is no “supposed” to with the products. What’s your goals? When would it be helpful for you? Ketones (base) will help you get into ketosis and give you no-carb energy. MCT powder is a type of fat that provides fast and lasting energy because it doesn’t need to be shuttled around your digestive system before being used as fuel.

  19. I really like the new Raspberry Lemonade from Pruvit. Do you have anything similar? It is actually the only flavor I enjoyed drinking.

    1. I like that one too! I’m trying the lemon pre-work out from perfectketones and see how it compares! I might blend in my own raspberry mixture to it! I workout every morning so the workout mixture just might be golden for me! Good luck

  20. I am super happy with this product. I have been taking it for about two weeks now. It has really helped my workouts, concentration and energy levels. I will be purchasing more.

  21. I have the chocolate and it’s great! I’m thinking about ordering the peaches flavor next, is there any reason I couldn’t put the peaches and cream in my coffee? Will heat do anything to the formulation as far as making it less effective?? And is the peaches and cream as “salty” tasting as the chocolate??? So happy I found your company. Now I just need to STOP eating extra carbs on the weekends!! Ha!

  22. Have you doen a similar comparison against Ketond or other keto supplements? I like many others am looking to get away from Pruvit and am currently debating my options.

  23. Do you use this as a meal replacement? I ordered the peach and just received it but I am unsure of how to properly use it.

    Thanks

    1. Hi Lacy! Sorry for my delay. Please allow more than 45 min for comments to be posted to the site. Great question. Perfect Keto is 70% D-BHB and 30% L-BHB. L actually acts as a signaling molecule to decrease inflammation and it converts to D after that.

  24. I was told by a pruvit rep that you have to do a triple dose of pk to get started. Is this correct? Also if you are in ketosis naturally through diet can you just donone dose per day to main ketosis as long as diet stays within keto value?

    1. Hi Andrea! I’m not sure where the rep got triple dose. How Perfect Keto is used will vary by person and will depend on the health goals you are trying to achieve. We do recommened starting with ¼ scoop first, heavily diluted in water. Ramp up from there, trying ½ scoop the second week or when you feel it’s appropriate, and then try a whole scoop 1-2 weeks in until you can gauge what’s most beneficial for you. Please take a look at some of our blogs and guides on how to keto, and let us know if you have any questions along the way 🙂

    1. Hello Joanie! Some people may experience a minor gastrointestinal (GI) discomfort due to their body newly being exposed to ketones. If you experience this, we recommend taking half a scoop then dialing it back up once your body adjusts. It’s also wise to limit additional salt intake and drink more water. Please type in “side effects” in our search bar to get to the page addressing common ketosis side effects.

  25. At 58, yoga 3x a week…I could surely use the energy, and to lose 10 lbs..without any caffeine Or feeling light headed.!!?? ..that would be grand! I’m skeptical for sure…

  26. Thank you for comparing these for us. My cousin swears by Pruvit, but I can’t afford $130+ every 20 days (or 10 if you do twice a day). I do like that Pruvit offers caffeinated options, what do you recommend to supplement with if your products do not offer caffeine?

  27. When drinking a product like this, are you automatically in a state of ketosis? If so, how long will your body be in ketosis? -I’m sure this depends on your diet- but supposing you are on a ketogenic diet.

  28. I did it the old fashion way 10 years ago. I lost 160 lbs in 7 months by just keeping my carb intake to under 20 grams. My Blood pressure returned not only to normal but low, my HLD LDL levels were beyond perfection. I have kept it off as well because I no longer crave nor like sugar. I have kept to a low carb regime and feel the better for it. I never had to use any products.. just common sense and diligence.

  29. hi alex or whomever is going to reply! i was going to buy ‘sample’ packs from pruvit, as get at discounted price right now. have been reading facts, side effects, etc., and came across another company, non mlm and highest goBHB, 11.7g. (ketond) i now see you do as well! i believe pricing similar too.
    i am looking at the product to help with weightloss, (do i need to buy product with mct also? and so pleased to learn all the other great helpful areas it works on one.
    inflammation is also a concern. this is taken care as mentioned earlier with L-BHB in your product. What then is the goBHB?
    is there a need to buy further supps – cal/mag, potassium and add sodium to meals? drink lots of water i suspect? any problem with heartburn issues? anxious to get going. need the energy, brain fog gone and weight to drop! sorry for all questions, but know dr. will ask me, lol!
    thanks so much …. next catch alex on some videos to learn more! bev?

  30. I’m fairly new to keto way of living , almost 2 months now. Your Chocolate Sea salt powder helps me get into that ketonic state and helps me with my motivation to stick with keto. I love it! Thank you for such a great product!

  31. Do you have to follow a keto diet of 30g carbs or less for perfect keto to be effective? Or can perfect keto work with any diet? I follow a Whole Foods plant based diet but am interested in trying perfect keto.

    1. This is a common question asked by those who are curious about implementing
      exogenous (supplemental) ketones into their daily routines without necessarily following a
      ketogenic diet protocol. To answer this question simply: Yes, you can benefit from consuming
      exogenous ketones regardless of the type of diet you may be following. Exogenous ketone
      supplementation provides your body with an instant supply of ketones creating a unique
      physiological state. Elevating your ketone levels can lead to a wide range of benefits including
      but not limited to:
       Increased and Sustained Energy
       Brain Enhancement and Protection
       Healthy Aging and Longevity
       Increased Performance and Recovery
       Weight Loss and Blood Sugar Control

    1. Hi Mary, we don’t have samples at this time, but we do stand by our products 100%. If you order through shop.perfectketo.com and aren’t satisfied with the product, you can certainly get a refund/exchange within 30 days 🙂

  32. I am considering ordering Perfect Keto because it appears that your prices are drastically lower than Pruvit and your science seems more sound. Still I am confused: what is the difference between the products that state they are ketone based and the MCT products? Does the MCT product have ketones? My daughter has lost 20 lbs on Pruvit in about a month and feels wonderful. Her headaches are gone, and her mood is better. I would like to achieve these results as well but I can’t afford it. Since my income is fixed and very low, please give me some direction, as I cannot afford to buy both at this time. Which product should I start with?

    1. Both the exogenous ketones and MCT Oil Powder provide you the energy, mental clarity, and focus to help you reach your goals. These products ultimately aid you in getting in/maintaining ketosis. MCT oil powder is derived from 100% coconut oil and does not have ketones; however, since MCT is a quick source of energy, it’s been proven to raise your ketone levels. For more information on this, please visit our blogs explaining when and how to use each product.

    1. Hi Clacey, yes our products are dairy-free. Since every woman’s body undergoes major changes during the period of pregnancy and breastfeeding, we highly recommend consulting with your doctor first to see if taking our products or any other supplements would be okay for you.

  33. Hello! My sister uses the keto Os but I am not all about the expense that comes with the Keto OS! I have Hashimotos Thyroiditis. Is this product ok for me to use?

    1. Hi Lindsay! We highly recommend consulting with your doctor first to see if taking our products or any other supplements would be okay for you.

    1. Hi Amanda, since every woman’s body undergoes major changes during the period of pregnancy and breastfeeding, we highly recommend consulting with your doctor first to see if taking our products or any other supplements would be okay for you.

  34. Pruvits Keto O/S claims they can prove you are in ketosis 45-60 minutes after drinking with keto stix or other at home testing. Does PK make any similar claims?

  35. I am doing the keto diet, watching my macros. I did Pruvit shake for a month and lost 6 pounds. I couldn’t afford Pruvit and thought I’d try Perfect Keto. I did and lost 2 pounds only that month… I see people all the time losing sooo much weight and I just do t know what I’m doing wrong. Can you help me?

    1. Hey Marley, it’s very normal to drop a lot of weight in the beginning of starting the keto diet and as your body adjusts, the weight loss may slow down. This happens to a lot of people but as long as you’re consistent and patient, it will pay off and the weight loss will follow. Keep it up and try to stay positive! 🙂

  36. I was wondering how fast perfect keto can put your body into ketosis? I know other products say it can work within an hour.

    1. Hey Jai, it depends on the person but after a full dose most people see ketones in their blood within an hour or 2…sometimes sooner.
