Suprep vs Magnesium Citrate
Introduction
For patients preparing for a colonoscopy or other types of bowel procedures, certain drugs that alter the contents and consistency of the gut can help in clearing the bowels and improving visualization during these tests. Suprep and Magnesium Citrate are two such solutions that are commonly used as bowel prep agents. They each work by increasing water in the intestine to stimulate bowel movements, but both have different levels of comfort and effectiveness.
Suprep is a combination of magnesium, potassium, and sodium sulfates. It works quickly within 30 minutes to an hour after intake but requires more volume to be consumed (about 2 liters divided into two doses).
Magnesium Citrate on the other hand operates through hyperosmotic action, drawing water into your intestines from surrounding tissues to induce defecation. It generally takes effect within three hours post-consumption with a lesser volume requirement compared to Suprep.

What is Suprep?
Suprep and Magnesium Citrate are both used as bowel cleansing agents, specifically for preparation prior to a colonoscopy. Suprep, which consists of sodium sulfate, potassium sulfate, and magnesium sulfate, was first approved by the FDA in 2010. It works by increasing the amount of water in the intestinal tract to stimulate bowel movements. This medication is available only with your doctor's prescription.
On the other hand, Magnesium Citrate is an over-the-counter solution that also promotes bowel evacuation by attracting water into the intestines through osmosis. Both medications are effective; however, their usage depends on personal preference and physician's recommendation.
While Suprep has a more targeted influence on bowel cleansing with minor side effects such as bloating or nausea, Magnesium Citrate may result in abdominal cramping due to its stronger effect on drawing fluid into the gut.
What conditions is Suprep approved to treat?
Suprep and Magnesium Citrate are both approved for bowel preparation prior to medical procedures:
- Suprep is specifically designed for colonoscopy prep, helping to cleanse the colon by causing a patient to have diarrhea.
- Magnesium Citrate also induces bowel movements and is often utilized as a laxative before diagnostic procedures or treatment such as colonoscopy.
How does Suprep help with these illnesses?
Suprep helps to prepare the bowel for a colonoscopy by inducing diarrhea and emptying the intestines. It does this by drawing water into the intestines, increasing the volume of stool and hastening its passage through the body. The active ingredients in Suprep are sodium sulfate, potassium sulfate, and magnesium sulfate which help maintain electrolyte balance while facilitating bowel movement.
Similarly, Magnesium Citrate is also used as a laxative to treat constipation or to cleanse the bowels before a surgery or colonoscopy procedure. The citric acid combined with magnesium works by increasing water in the intestines that softens stools making them easier to pass.
Both medications work towards similar goals but operate differently at a chemical level. Therefore, choosing between these two would depend on factors like personal health history, comfortability with side effects and doctor's advice.
What is Magnesium Citrate?
Magnesium Citrate, an over-the-counter medication typically used to treat occasional constipation, works by pulling water into the intestines. This action usually results in a bowel movement within 30 minutes to 6 hours. As a saline laxative, Magnesium Citrate is often chosen for its gentle yet effective relief of constipation and irregularity. It has been available as a non-prescription drug since the early 1900s and comes in liquid form that can be mixed with a drink.
Unlike Suprep, which is intended specifically for bowel prep before colonoscopies or other medical procedures and requires prescription, Magnesium Citrate is widely accessible without needing any prescriptions from your doctor. Although side effects are generally mild (including stomach cramps or nausea), they differ slightly from those associated with Suprep due largely to their different modes of action on the digestive system.
What conditions is Magnesium Citrate approved to treat?
Magnesium Citrate is an over-the-counter medicine known for its effectiveness in treating constipation and preparing the bowel for medical procedures. It works by increasing water in the intestines, which can induce bowel movement. Here are some of the conditions Magnesium Citrate is used to treat:
- Occasional constipation
- Bowel preparation before colonoscopy or surgical procedures
How does Magnesium Citrate help with these illnesses?
Magnesium Citrate is a salt of magnesium and citric acid that has potent laxative properties, making it very useful in preparation for medical procedures like colonoscopy. It works by increasing the water content and volume in the intestines, which stimulates bowel motility, aiding in the clearance of stool from the body. Its actions are similar to those of Suprep Bowel Prep Kit; however, Magnesium Citrate does not contain an additional stimulant laxative as Suprep does. Since it does not have this additive component, some patients may respond better to Magnesium Citrate than to combined preparations such as Suprep when they need mild-to-moderate bowel cleansing without excessive stimulation.
How effective are both Suprep and Magnesium Citrate?
Suprep and Magnesium Citrate are both effective over-the-counter options for bowel cleansing prior to colonoscopy. They were initially approved by the FDA decades apart, with Suprep gaining approval in 2010 and Magnesium Citrate having been available since the late 19th century. Since they act on different mechanisms within the digestive system, they may be prescribed under different circumstances.
The efficacy of Suprep and Magnesium Citrate in providing adequate bowel preparation was directly studied in a randomized clinical trial in 2013; both solutions exhibited similar efficacy at thoroughly cleaning the colon as well as comparable safety profiles[1]. In this study, there were no significant differences between patients receiving Suprep or Magnesium Citrate when it came to patient satisfaction or adverse events.
A systematic review published in 2007 indicated that low-volume solutions such as Suprep may be preferred due to their smaller volume making them easier to ingest[2]. Additionally, unlike many other preparations, Suprep does not require dietary restrictions on the day before the procedure. The same review noted that while magnesium citrate is also an effective option for bowel prep, its larger volume (up to three times more than supprep) can make it less tolerable for some patients.
On balance though, both have proven effectiveness at cleansing the colon prior to procedures like a colonoscopy. The choice between these two options will often come down eligibility criteria (for example kidney function tests), personal preference regarding taste and texture of solution ingested versus how much needs ingesting along with cost considerations.

At what dose is Suprep typically prescribed?
For bowel preparation prior to colonoscopy, Suprep is typically prescribed as a split-dose regimen. The first bottle of solution should be taken the day before the procedure and the second bottle on the day of the procedure, each followed by additional water intake. On the other hand, Magnesium Citrate is generally used for occasional constipation relief or bowel cleansing before surgical procedures. Dosage can range from 1/2 to full 10 oz bottle depending on patient's age and desired speed of effect; this should not exceed two bottles in 24 hours without professional medical advice.
At what dose is Magnesium Citrate typically prescribed?
Magnesium Citrate treatment for bowel cleansing generally starts with a 10 oz bottle, which should be drank followed by an 8 oz glass of water. If necessary, this can then be increased to two 10 oz bottles spaced roughly several hours apart. The maximum dose is typically two bottles in one day; however, it's essential to drink plenty of clear liquids before, during and after the use of Magnesium Citrate to prevent dehydration. Always consult your doctor if there is no response or incomplete bowel evacuation after using the recommended dosage.
What are the most common side effects for Suprep?
Common side effects of Suprep include:
- Nausea
- Abdominal fullness, bloating or cramping
- Vomiting
- Overall discomfort
On the other hand, Magnesium Citrate also has potential side effects such as:
- Diarrhea
- Stomach cramps or pain
- Gas and indigestion
- Feeling of warmth or flushing
Are there any potential serious side effects for Suprep?
While both Suprep and Magnesium Citrate are used to prepare the bowel for medical procedures, they can have different side effects. Here's what you need to watch out for:
- Signs of allergic reaction: hives, difficulty breathing, swelling in your face or throat
- Electrolyte imbalance symptoms: dizziness, irregular heartbeat (too fast or too slow), severe thirst, increased urination, leg cramps or muscle weakness, constipation
- Dehydration symptoms: extreme thirstiness that cannot be quenched with drinking water; feeling very dry (e.g., dry skin/mouth/eyes); feeling faint/dizzy when standing up suddenly from a sitting position; rapid heart rate; confusion/disoriented thinking
- Kidney problems manifestations: lower back pain on one side; blood in urine (reddish/pinkish color); decreased amount of urine produced despite high intake of fluids
- Severe stomach pains/cramps
- Vomiting that doesn't stop
If you notice any of these signs while using either Suprep or Magnesium Citrate, seek immediate medical attention.
What are the most common side effects for Magnesium Citrate?
Magnesium Citrate, often used as a laxative for bowel preparation prior to medical procedures, can cause the following side effects:
- Stomach discomfort or cramping
- Diarrhea or loose stools
- Nausea and vomiting
- Dehydration symptoms like increased thirst, dry mouth, decreased urination
- Dizziness or light-headedness due to fluid loss
- An electrolyte imbalance which may result in weakness, irregular heartbeat. Remember that while these are potential side effects of Magnesium Citrate consumption, not all individuals will experience them.
Are there any potential serious side effects for Magnesium Citrate?
While Magnesium Citrate is generally well-tolerated, it can occasionally cause serious side effects. If you experience any of the following symptoms after taking Magnesium Citrate, seek immediate medical attention:
- Signs of an allergic reaction, such as hives; difficulty breathing; swelling of your face, lips, tongue, or throat
- Severe nausea or vomiting
- Rectal bleeding or blood in stools
- No bowel movement within 6 hours of use
- A light-headed feeling like you might pass out
- Elevated heart rate and/or palpitations
- Unusual changes in mood or behavior
These are not all the potential side effects that may occur with this medication. Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances.
Contraindications for Suprep and Magnesium Citrate?
Both Suprep and Magnesium Citrate are commonly used as bowel prep solutions before medical procedures like colonoscopies. If you notice severe symptoms such as rectal bleeding, persistent stomach pain, or vomiting while using these medications, please seek immediate medical attention.
Neither Suprep nor Magnesium Citrate should be taken if you have kidney disease, a blockage in your intestines or stomach (gastric retention), or an ileus. Always inform your healthcare provider about all the medicines you take; if you are taking any drugs that affect kidney function such as diuretics ('water pills'), angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), NSAIDs like ibuprofen and naproxen among others — it may increase the risks associated with both Suprep and Magnesium Citrate usage.
It is also noteworthy that these products can interact with other medications by changing how they work or increasing their side effects which may lead to serious complications hence require special caution when administered concurrently with other drugs.
How much do Suprep and Magnesium Citrate cost?
For the brand name versions of these drugs:
- The price of a Suprep Bowel Prep Kit typically averages around $100–$130, depending on your location and insurance. This kit is used as a single dose for colonoscopy prep.
- A bottle (300 ml) of Magnesium Citrate Oral Solution USP (Citroma) averages about $3-$6.
Thus, if you are preparing for a procedure like colonoscopy, Suprep is significantly more expensive than Magnesium Citrate. However, it's critical to understand that cost should not be the primary consideration in determining which bowel prep method is right for you; efficacy and tolerability are key factors too.
When it comes to over-the-counter options:
- Generic magnesium citrate solutions can be found at prices as low as $2 - $4 per 300ml bottle.
- There is no generic version available for Suprep currently, so patients needing this specific preparation would need to opt for the brand-name product.
Popularity of Suprep and Magnesium Citrate
Suprep, a bowel prep kit for colonoscopy procedures, was prescribed to about 3.8 million people in the US in 2020. The drug accounted for approximately 10% of all prescriptions given to prepare patients for colonoscopies. Suprep is known as a sodium sulfate-based laxative and has been steadily increasing in use since its introduction.
Magnesium Citrate, on the other hand, is an over-the-counter medication that also works as a saline laxative and is commonly used by individuals self-treating constipation or preparing for medical procedures like colonoscopy. Although exact prescription numbers are not available due to its over-the-counter status, it's estimated that millions of Americans utilize Magnesium Citrate each year based on sales data. The prevalence of Magnesium Citrate usage has remained steady over recent years due to its effectiveness and affordability.
Conclusion
Both Suprep and Magnesium Citrate are widely used for bowel preparation prior to a range of procedures, such as colonoscopy. They have been favorably reviewed in numerous studies for their efficacy compared to other laxatives. Both products work by increasing the amount of water in the intestinal tract to stimulate bowel movements. However, they differ somewhat in their mechanisms: Suprep is an osmotic laxative that contains sodium sulfate, potassium sulfate, and magnesium sulfate; while Magnesium citrate also works osmotically but solely relies on magnesium.
Suprep is generally prescribed by physicians due its proven effectiveness and tolerability despite being more costly than over-the-counter alternatives like Magnesium Citrate. It comes as a split-dose regimen which may improve patient compliance with taking the entire prep.
On the other hand, Magnesium Citrate is less expensive and can be conveniently purchased without prescription. Yet it's often associated with a higher likelihood of causing abdominal cramping.
Although both agents are usually well-tolerated, side effects like bloating or stomach cramps can occur with both medications although these tend to be temporary. Additionally, people should monitor themselves closely when using either product especially those with kidney disease or heart problems.
