For individuals who enjoy a smoke, even in states where marijuana is legal for recreational use, employment drug testing is a pain in the ass. According to Statistics Brain, 56% of American employers make pre-employment drug tests mandatory. The annual cost of these tests is $3.7 billion. If this seems like a lot, consider that employers lose an estimated $85 billion annually because of employee drug use.

Urine tests are by far the most popular and marijuana is the most commonly found drug. Therefore, if you’re close to the job of your dreams, use weed, and are called in for a drug test, your only hope of passing it is by using one of the myriads of detox methods online. The Certo Drug Test detox has been championed as one of the best ways to get clean in a hurry; but is it all hype or the real deal? Read our full review to find out.

What Is Certo?

‘Certo’ is a trademarked Kraft brand name for liquid fruit pectin. The company has another fruit pectin product called ‘Sure Jell,’ which is essentially the same thing as Certo, but with different packaging. Certo has been available in the United States for over 100 years and is used to make jello, but it has only recently become associated with detox.

Fruit pectin is a naturally occurring polysaccharide found in fruits – particularly sweet fruits such as peaches, pears, apples, and berries. Polysaccharides are a digestible form of fiber that consist of long-chain monosaccharides. The most common use for fruit pectin is as a thickening agent to make jams and jellies. When heated along with sugar, fruit pectin produces a thick, gel-like substance with the consistency of Jell-O. Since it is a highly soluble fiber, however, fruit pectin also does a good job of detoxifying your system by “absorbing” unwanted molecules (i.e. THC metabolites) and expelling them from the body via feces.

How Certo or Fruit Pectin Can Help Detox Your System

One of the main misconceptions about Certo is that it traps toxins by ‘coating’ the stomach. In reality, it works like any fiber does and enables the body to absorb and expel toxins via fecal matter. As fruit pectin forms into a gel, it absorbs more liquids than ‘normal’ fibers. And since toxins that normally leave the system via urine end up in the stool, Certo is theoretically a great way to pass a urine drug test.

The simplest explanation of how Certo detoxes your system is that the fruit pectin ‘traps’ the toxins and breaks them down into smaller metabolites that are easier to remove. The process typically takes 60 minutes and can last 3-5 hours in total. Eventually, the toxins are released and leave the body via urine and feces.


Since Certo is high in fiber and carbohydrates, it produces an insulin boost in healthy adults. This causes the body to store calories for energy, rather than using them. The body also burns and metabolizes fat for energy; when fat-soluble toxins are released from fat cells, they end up back in the bloodstream, the saliva, the urine, and other fluids. The fast-acting carbs in Certo cause an insulin spike, which prevents fat burning for a short period and shuffles the herbal detoxing minerals and nutrients in the concoction.

Finally, Certo absorbs the toxins that are naturally released from the body via stool, urine, and other bodily fluids. Toxins find it easier to leave the body via fluids, but Certo’s fiber absorbs the fluids in the intestines and stomach, and this action results in toxin release via solids. Unlike other ‘quick fix’ detoxes which you take immediately before a drug test, you have to begin the Certo plan 24 hours before the test.

As well as Certo works for flushing out unwanted toxins from the body, it does an equally good job of flushing out vital compounds as well. If you plan on using Certo as a detox method, here are three key things to keep in mind to ensure that you do it in the healthiest way possible:

WaterThere is no better natural detox method than water. When you’re well-hydrated, the body knows there is no need to retain fluids, and it begins the process of removing toxins. However, you have to be careful not to drink too much water; overhydration can actually deplete mineral stores in bodily fluids, so when you consume too much water, you’re flushing out both toxins and important nutrients. If a drug test shows a lack of minerals in your urine, questions may be asked.
VitaminsHealthy urine contains B vitamins and, since the detox process can wash out some nutrients, it’s a good idea to replenish them to avoid suspicion.
CreatinePopularized by bodybuilders, creatine is a mineral that’s typically obtained by eating fish and red meat. It is present in the urine and again, detoxing can deplete it – so you need to consume some to make your urine look genuine.

Certo Drug Test Instructions

The Certo Drug Test detox is pretty easy to follow. You’ll see a variety of instructions online – ignore them! The following method and ingredients have been shown countless times over as the most likely to work.


You Will Need:

  • Two packets of Certo (Sure Jell or any other type of liquid fruit pectin will also work).
  • Two 32oz sports drinks (Gatorade is popular).
  • Creatine monohydrate.
  • Multivitamin capsules.
  • Vitamin B2 (not strictly necessary).

Once you have the above, the steps are pretty simple to follow:

  1. Drink as much water as you can in the two days leading up to the drug test. Water will help flush out your toxins, and those that remain will be sent to your intestines – which is exactly where you want them in order to get the most out of your Certo detox.
  2. Mix one pack of Certo with one of the sports drinks. Give the mixture a shake, and drink it before going to bed on the night before the drug test.
  3. On test day, drink as much water as you can about three hours before the test.
  4. About 1-2 hours before the test, mix the second packet of Certo with the other sports drink.
  5. Consume it along with a multivitamin and B2 capsule.

In theory, the Certo method should allow you to “pass” a urinalysis for at least three hours. If you’re in a hurry, consume a packet of Certo, the 32oz bottle of Gatorade, and a similar amount of water an hour before the test. It won’t work as well as the 24-hour window, but as a last ditch effort, it could help you scrape by.

Does Certo Detox Drug Metabolites?

Typically, yes! That’s why it is such a popular detox method for marijuana users that are trying to pass a urinalysis. As you know, THC is the psychoactive compound in cannabis that’s famed for getting you high. It is one of over 100 identified compounds in weed. The body breaks THC down into THC-COOH, which is actually the metabolite that most THC drug tests look for.

Metabolites, including THC-COOH, flow through the body and bloodstream. While a small amount of metabolites are expelled, most get absorbed by lipids and ultimately get stored in fat deposits throughout the body. The metabolites remain deposited in fat stores until the fat is re-released into the bloodstream to be used as energy. Once the fat has been ‘consumed’ by the body via a normal metabolic process, the metabolites are released and expelled via urine, sweat, saliva, and feces. The body naturally detoxes over time, but the process can take weeks – which is bad news for weed users facing a drug test.

This is where Certo comes in handy. Fruit pectin speeds up the detox process, and though Certo’s detoxing capabilities are not scientifically proven, it has proven very effective for countless marijuana users prior to taking a drug test.

Things to Watch Out for When Purchasing Certo

Remember, don’t waste your money on fancy branding; fruit pectin is all you need, and it is widely available in most chain grocery stores. The entire method is inexpensive, so don’t be fooled into spending cash you don’t need to. And most importantly, remember that there is no guarantee the Certo Drug Test detox will work!

Additionally, you will definitely decrease your chances of passing if you make one of these mistakes:

Leaving it too lateCerto takes at least an hour to work, and it is best to use two doses; one the night before, and one around two hours before the test.
OverhydrationAs well as flushing out nutrients, drinking too much water will make you feel ill – and you could throw up the Certo mixture.
Skipping the sports drinkThe abundance of electrolytes in sports drinks are a crucial part of the Certo detox process.
Not using creatine There is creatine in urine, but if you flush it out without replacing it, your test will likely be flagged.

Final Thoughts on Certo Drug Test Detox

In summary, the Certo Detox Method seems so simple that it’s hard to believe it could work. And again – it’s certainly not a guaranteed method of passing a drug test. There are a number of factors that dictate the effectiveness of the Certo method, including individual factors such as age, weight, gender, body type, metabolism, and marijuana usage.


Furthermore, there is no scientific evidence to back up the claims that Certo works as an effective marijuana detox. (Cynics argue it is simply the large volume of water involved that helps people get through their test). While it is possible that the fiber in pectin helps temporarily keep toxins from leaving your system via urine, there is also a chance that simply drinking large quantities of liquid dilutes your urine to the point where you can pass a drug test.
