We wanted to get to the bottom of things with Keto OS. Right off the bat there was an outpouring of negative reviews on taste, making our team jump straight into the ingredients. Then we noticed a rash of comments about side effects, which was enough to make us tackle the science head on. We took the information we found, summarized it, and now share with you – the truth about Keto OS.
What is Keto OS?
Pruvit Keto OS supplement is a powdered drink offering weight-loss support. If this drink is as terrible as some of the customer comments make it out to be, we have a hard time believing that anyone is seeing results.
Before we get into the ingredients, according to the company itself, they can cause side effects. “Supplementing with KETO//OS or following a ketogenic diet can cause a slightly diuretic effect, and can deplete magnesium, potassium and sodium stores.” And that wasn’t all.
Before we get ahead of ourselves, here are the Keto OS ingredients:
- MCT Powder
- Caffeine 
Keto OS Max offers the same, but l-leucine, l-taurine, and a few others are added. Just one scoop or packet a day is supposed to force you into ketosis , so your body burns fat instead of carbs. This idea is what low-carb diets are based on.
Ketosis is not to be confused with ketoacidosis, a medical condition that can be life-threatening.
Pruvit, the makers of Keto OS, started online in 2013. You have various options to choose from on the official website including a canister of powder or prepackaged servings, which makes the Keto OS diet plan a bit easier. We like the addition of caffeine but that’s not the best part.

Keto OS Drink – “Why Do Ketones Taste Bad?”
The first issue we found with Keto OS ingredients came with a taste that was unpleasant to some. “If you’re supposed to use the Keto OS drink to lose weight, how can you if you’re put off by the taste,” asked our Research Editor.
“It tastes like 10 packets of sweet and low in one glass of water, tastes very unnatural I would rather drink dirt,” one user explains.
“No changes occurred in a week! It tastes awful and only gave me headaches,” according to a Keto OS review. 
Another says, “Couldn’t even drink.”
Not everyone was unhappy. Let’s look at another example:
“Taste is good, added extra ice and made in blender,” said a dieter of Keto OS ingredients.
Keto OS Side Effects – “Yes, According to Pruvit”
The taste wasn’t the only problem that came up. We also found reports of Pruvit Keto OS side effects. If the product pushes the user into ketosis, some adverse reactions could be attributed to what’s often called “Atkins Flu.”
Make no mistake about it, the majority of people do feel like crap for a few days.
As the body adjusts from burning carbohydrates to fats for fuel, fatigue, muscle aches and headaches are common. “Muscle aches and vomiting within 30 minutes to one hour after each ingestion ensued,” explains one person who tried the Keto OS diet plan.
“Numerous times it made me sick to stomach, unproductive and a bit wired,  even without the caffeine version,” a customer reports. Another user claims, “I took 1/2 a packet and 15 hours later I was still wired and jittery from it. My heart was racing.”
But you’re probably wondering, “Does everyone feel like this?” Nope. Some people feel good about Keto OS supplements.
“It helps keep you in ketosis, without horrid side effects,” commented a customer.
“I drink half a pack on workout days and it gives me so much energy,” stated another.
Based on our research, it takes something that doesn’t seem important, like a few muscle aches, to cut down your chances of long-term success. There’s an issue if customers don’t have great things to say about Keto OS results or Keto OS Max.
Keto OS Results – “Can This Really Be True?”
Here’s where things get interesting with the Keto OS diet plan. There are 110 calories in each serving. But, when you combine the fat, carbohydrates and protein, it only adds up to 75. Where do the rest come from?
Another problem is the fact that none of the ingredients have anything to do with starting ketosis.  You also have to consider the fact that there are 970mg of sodium, which is considered quite high.  That’s nearly 50% of your recommended daily intake.
We believe science is critical, but we couldn’t find any to back claims of Keto OS results. Also: read our Burn HD Weight-Loss Kit review »
The Bottom Line – Does Keto OS Work?
Can we be totally honest with you? We like that it contains caffeine, but we’re concerned about no research backing the claims. You have to consider the fact that no supplement can kick you right into ketosis and the price is outrageous at $85 for two weeks.
Is a kick in metabolism what you’re looking for? We suggest trying out a product that comes with scientifically tested ingredients that work to help you lose weight without any risk of harsh side effects. The price should not break the bank.
