Pruvit Keto NAT All Natural Ketones

What is C-Med 100?

Pruvit ketones have been advancing for some time and the additional of AC-11 in the new Keto Max and Keto Kreme formulas was one such advancement.

C-Med 100 is the new trade name for the AC-11 DNA repair (Inner Bar of Uncaria Tomentosa) and Keto NAT contains a proprietary amount of C-Med 100.

The Keto Reboot Kit also contains AC-11 within its Signal OS pills.

What is R-Beta Hydroxybutyrate?

Beta Hydroxybutyrate (BHB) is the ketone body found in exogenous ketone supplements which are typically bound to salts and minerals. Pruvit’s Keto OS, Keto MAX and Keto NAT formulas are all a bit different. (What are the effects of BHB? Link to study)

Pruvit’s original Keto OS formula used a racemic blend of ketone salts using both the D+L isomers, and some with MCT.

The Keto Max formula used single isomer BHB which are bioidentical to the ketone bodies your liver makes. This is one reason why Keto Max was a much stronger formula, roughly 40% stronger than the OS. It has a quicker uptake, quicker spike and is more rapidly absorbed.

The new Keto NAT formula is a Max upgrade – more bioavailable and should provide a stronger effect i.e. more energy, better appetite control, and better performance. And there are no chemicals used to process the BHB – they are fermented.

There are no other exogenous ketones supplement on the market with this technology. Keto NAT is Pruvit’s patent pending formula. 

Keto NAT vs Keto Max

The Keto NAT flavors have the same great taste as Keto Max, but the NAT gives me a little more energy, focus and the appetite suppression is better.  I love these benefits!

Since writing this I’ve tried the Fairy Dust, an amazing sugar plum/apple flavor, the new Unleashed Ruby Rush which is a ruby red grapefruit flavor, Unleashed Eclipse which tastes like blackberries, and the Keto NAT Celebration which is a pear flavor.

The new Keto Unleashed line is the NAT formula but is is amped with 30% more ketones + caffeine. Amazing all-day energy and high ketone levels!

User Questions and Answers


Q: I am on keto diet. Because of cost,would it be effective if I took product every other or 3rd day? -Diane

A: Hi Diane, one day is a therapeutic dose, and twice a day is optimal dose. You could definitely use it as a Keto friendly energy drink, or if you get off track with diet you could drink one to get right back into ketosis because it's going to raise your blood ketone levels immediately. I think you'd really notice the days when you drink it and when you don't drink it, you're just going to feel that much better. I think you should give it a try and see how you feel using it now and then vs everyday. Check out my Keto Samples blog if you'd like to try some samples before committing. Let me know if I can help. Thanks! Rachel

Q: when will keto nat be in stock please -jodey

A: Hi! I have Keto NAT samples for sale on my Keto samples blog as a preorder item. They've only had one 24 hour flash sale so far. Not sure when the next release will be! I should be receiving my first shipment of 8 boxes in about a week. Thanks! Rachel

Q: I'm trying to find the difference between NAT and MAX. And, one site said the MAX is being phased out! Help! -judy

A: Hi Judy, I discuss the difference in this blog post - did you read it? NAT is the new MAX - it's the same flavors but it's an even stronger, more bioavailable product. Fermented all natural ketones. It's basically a Max upgrade so not to worry! All Max flavors will become NAT. xo Rachel

Q: Does it matter what time of the day you drink it? -Gina

A: Hi Gina, some people like to drink first thing in the morning and then another serving early afternoon.. Others just drink it when they need the energy! Like after lunch for sustained energy the rest of the day. You can drink it anytime. I personally like to use it as an intermittent fasting tool and as a preworkout supplement, it gives me great energy all day no matter what I'm doing, I conquer the day with no crashes! Rachel

Q: When is the best time to eat after or before drink -Cindy

A: Hi Cindy, ketones are a fuel source, so it's best to drink them on an empty stomach and use them as an energy source and delay eating until you are hungry. Sometimes I'll eat eggs first (just a low carb/keto meal) and then drink the ketones an hour or so later in the afternoon. It's best drink them separate from food. Thanks! Rachel

Q: what is the mg of c-med-100 in each packet? it also states very small on the back..."must be consumed with SIGNAL/OS for DNA repair". What is signal/OS? Is that already in the packet? Thanks! -kate

A: Hi Kate, great question! c-Med100 is a new trade name for the AC-11 DNA repair element in Pruvit's products. You can read my blog post about AC-11 here. From the research I've done,  I believe there's 350 mg or less of AC-11 in a Keto NAT. Hard to say exactly since they don't list the exact mg since it's a proprietary formula (I've done some pretty thorough investigation on this subject).

Some studies show further benefits (ie. DNA telomere length) with 750mg of ac-11, thus the notice on the Pruvit packages. AC-11 is a pure water-soluble extract with an impeccable safety record that you could take a lot more of, but benefits seem to peak around 750 mg. 350 mg to 750 mg is the recommended dose with study data showing benefits. Most companies will not use 750 mg due to cost.

The Signal-OS pills from Pruvit also contain AC-11 but those are currently only available in the Keto Reboot kits, and not yet as a stand alone product. Signal OS pills also contain 350 mg of AC-11 (I'll attach a picture here of the Signal-OS ingredients label). However, you can purchase pure AC-11 (same source as Pruvit's) from Healthycell.

They offer Healthycell AC-11 pills, and I take the Healthycell Pro which is a multivitamin, they both have about 350 mgs AC-11 in each pill.  While it's certainly not required to supplement with additional AC-11 to receive a great benefit from Pruvit's products, if you're interested in maximizing the anti-aging benefit, then it's something to consider.

Hope this helps. I'm sure Pruvit will offer the Signal-OS pills by the bottle at some point, they recently did in the Keto Reboot Excel kits but those aren't available this month.

Q: A new flavor " Apple" in cans just came in by your company do U have any samples? &/or what do U recommend - I usually drink 2 Monster orange O calorie per day & morning KETO coffee but still tired all the time!!! Would this help (the new apple flavor product & is it in cans only or packets? -LAURIE

A: Hi Laurie! Well I ordered a case of the Keto Up Apple today! If you drink that much monster I would definitely give it a try - it's so much better for you! The new apple flavor is in cans only, it's a carbonated energy drink. I don't think it's going to make sense for me to mail samples of a can....but if I can figure out a way to economically ship one then I will... You can watch the Keto Up video here to learn more about it.  I'm going to email you directly. Thanks! Rachel

Q: For someone who is iron defficant , are these keto products a good way in helping me?? -B

A: Hi Brenna, there is no iron in any of the ketone supplements, these are a multivitamin type of supplement - it's mostly BHB (ketones) plus amino acids. Let me know if you have more questions or you can email me directly at [email protected]. Thanks!

Q: When is best time to drink nat ketones -Samantha

Q: Will drinking it after my bullet proof coffee mess with the weight loss part of the diet -Lisa

A: Hi Lisa, weight loss comes from being in an energy deficit. Ketones + fasting make it a lot easier to eat less so you can stay within your goal. Be careful with bulletproof coffee... some of the blends I've seen people make are huge calorie / fat bombs. I do like to add a little MCT to my coffee, but I've seen people make bulletproof coffee into a 500 calorie drink - which isn't as filling as real food and may put you at a disadvantage for fat loss. But to answer your question, I would wait some hours after your bulletproof coffee to drink your Keto NAT. Better yet, drink your NAT first and fast until you are hungry, then drink the BPC and keep fasting....  If your intention is to fast, ketones won't break a fast, but the fat/calories in a BPC will... The Keto Kreme is a great choice to make a BPC while keeping the calories to a minimum. xo Rachel

Q: I understand that we should have Keto- Nat every morning. What is he product available when we are sick, or have to miss a meal that replaces a meal? Do you have Keto Nat for am and also Keto Nat for pm? Obviously, I am new, but want to order the correct starters. Thanks -Linda

A: Hi Linda, there is a charged Keto NAT (with caffeine) for morning/daytime use and there's a decaf version you can use if you want a second serving, or if you're just sensitive to caffeine or avoiding it. Pruvit doesn't really make a meal replacement product per se, but the Keto Pro is great for a snack or as a post workout meal to hold you over. It's decaf and contains ketones, MCT, and protein. NAT and Pro are my two favorite products! You can check out what's available for sale here. The Top Picks box would be an amazing first purchase - so many yummy special flavors they don't normally sell as a mixed box. Thanks! xo Rachel
