MagO7 Digestive Cleanse is a 180-capsule magnesium oxide supplement from NBPure. Adults take it at bedtime to ease occasional constipation and bloating. The brand has sold the formula for over 25 years. It markets the capsules as a gentle overnight cleanse. Founder Danna Pratte created the original recipe.
MagO7 draws water into the bowel and softens stool by morning. Reviewers praise the gentle action, and Amazon shows a 4.6 star average from 48,175 ratings. Side effects include loose stools at high doses. People with heart or kidney disease need a doctor first. The 180-capsule bottle costs $41.95 on Amazon. Results often show up by the first morning.
The verdict depends on your goals and health. Magnesium oxide has real support for constipation, but the detox claims lack proof. Read on to learn the dosing routine, the safety limits, and whether the price fits your budget. Then decide with facts. You get a clear and honest answer without hype.
What Is MagO7 Digestive Cleanse?
MagO7 Digestive Cleanse is an oxygen-based magnesium oxide supplement sold as an overnight colon cleanse and constipation aid. NBPure sells the 180-capsule bottle, and Aerobic Life is the listed manufacturer. The formula targets adults who want gentle relief from backed-up waste and bloating without harsh stimulant laxatives. Men and women both use it.
Our team at Eat Proteins sees MagO7 as one of the best-known names in the cleanse aisle. NBPure, a Phoenix, Arizona company, says the product has sold over 15 million bottles. Founder Danna Pratte developed the original formula more than 25 years ago.
What Is in MagO7 Capsules?
MagO7 capsules contain magnesium, potassium, organic rice flour, citric acid, and vegetable cellulose. The label lists five ingredients in total. The magnesium oxide compounds carry oxygen, while potassium supports fluid balance in the gut. The capsule shell is plant-based, so the product stays vegan and easy to place in most diets. The list stays short.
Label Ingredients:
- Magnesium oxide compounds
- Potassium
- Certified organic rice flour
- Citric acid
- Vegetable cellulose capsule
The brand says the formula is gluten free, non-GMO, and cruelty free. NBPure says accredited third-party labs test each batch for purity. Here’s the thing: the company also avoids artificial flavors, sweeteners, dyes, and fillers.
How Does MagO7 Work?
MagO7 works as an osmotic cleanse that pulls water into the intestines to soften stool. Magnesium oxide reacts with stomach acid and raises osmotic pressure in the digestive tract. Water then moves into the bowel. The added volume nudges the intestinal walls to push waste out, usually by the next morning. Relief typically arrives within about eight hours.
How the Cleanse Works:
- Take three capsules at bedtime with a full glass of water.
- Magnesium oxide draws water into the colon overnight.
- The softened stool moves out as a bowel movement the next morning.
Potassium plays a supporting role. Why does it matter? The mineral helps keep electrolytes balanced as fluid shifts into the gut. In fact, the brand says potassium also supports smooth muscle contractions, so the morning bowel movement feels gentler.
Does MagO7 Really Relieve Constipation?
Yes. MagO7 helps relieve occasional constipation, and magnesium oxide has clinical support for that purpose. NBPure’s press release cites gastroenterology guidelines that endorse magnesium oxide for chronic constipation. Amazon shoppers rate the bottle 4.6 out of 5 across 48,175 ratings, which shows steady real-world results. Reviewers repeat that result.
Does it work for everyone? No. Results vary with diet, hydration, and dose. To be clear, the supplement treats occasional constipation and does not replace medical care for ongoing bowel problems.
Does MagO7 Ease Bloating?
Yes. MagO7 eases bloating for many users by clearing the backed-up stool that causes the swelling. Several reviewers describe a flatter stomach after a nightly dose. One reviewer says a distended belly turns almost flat after taking the capsules. Bloating from food intolerance or other causes may not change. Gas relief often follows the first bowel movement.
Why does the relief show up so fast? Stool volume drops once the bowel empties. The good news? Many users report this change by the first morning.
What Do MagO7 Reviews Say?
MagO7 reviews are overwhelmingly positive across Amazon and the NBPure site. Amazon lists a 4.6 out of 5 average from 48,175 ratings. NBPure shows 6,742 on-site reviews, and 88 percent give five stars. The bottle also ranks number 2 in Detox and Cleanse Weight Loss Products on Amazon. Few supplements match that volume of feedback and customer approval.
Brand-run review sections tend to skew positive. Should you trust them alone? No. So, the Amazon average gives the fairer picture. Is 4.6 stars still strong for a supplement? Yes, especially at nearly 50,000 ratings.
What Do Users Praise?
Users praise MagO7 for gentle overnight relief without cramping. Reviewers describe softer stools, less bloating, and a predictable morning routine. One reviewer in their sixties says the constipation is gone and the pain never shows up. Others say the capsules work better than stimulant laxatives. Many call the relief reliable and gentle on the body.
What Reviewers Like:
- Gentle overnight action
- No cramping for most users
- Less bloating by morning
- Relief after other products failed
- Help with constipation on GLP-1 medication
One buyer began a GLP-1 medication and went four days without a bowel movement. The capsules fixed the problem with no issues. In plain English: reviewers value the predictable timing.
What Are the Common Complaints?
Common complaints are few, and most center on dosing, capsule size, and the need for plenty of water. About 12 percent of on-site reviews fall below five stars. Some users need extra capsules to get a result, while others get loose stools at the standard dose. Trial and error sets the right amount. Most issues are easy to fix with small dose changes.
Swallowing the large capsules bothers some buyers. The brand suggests squeezing the capsule to shorten it or switching to the powder. And here’s the catch: low water intake weakens the effect.
What Are the Side Effects of MagO7?
MagO7 can cause loose stools, diarrhea, and mild cramping, especially at higher doses. Those effects are typical of any magnesium oxide product. NBPure says its formula works without cramping or urgency for most users. Individual reactions still vary, and the dose matters most when side effects appear. Starting with a low dose keeps the risk small.
Nausea and gas are also possible. Does water really matter? Yes. Skipping water raises the odds of stomach upset. Bottom line: the brand says to drink at least 8 ounces (240 ml) of water with every dose.
Who Should Avoid MagO7?
People with heart disease or kidney disease need a doctor’s approval before taking MagO7. The safety label states that the magnesium serves as an oxygen delivery tool and is not a magnesium supplement. Kidneys clear extra magnesium, so poor kidney function raises the risk. Cardiac patients face similar caution. Children are excluded from the label as well.
Ask a Doctor First If You Are:
- Living with heart disease
- Living with kidney disease
- Pregnant or nursing
- Taking prescription medication
- Buying for a child under 18
The product is labeled for adults. Can parents give it to kids? No. Short answer: anyone with a health condition should check with a physician first. Our experts at Eat Proteins repeat that advice for every cleanse product.
Is MagO7 Safe and Legit?
Yes. MagO7 is a legitimate product from a real company with more than 25 years on the market. Healthy adults tolerate the capsules when label directions are followed. Supplements get no FDA approval before sale. The safety record rests on the maker’s testing and long consumer use. The brand sells widely in major retail stores and on Amazon alike today.

Taste for Life Magazine named MagO7 the best cleanse supplement of 2025 in February 2025. What’s more, the Amazon listing shows NB Pure, LLC as the seller. The seller name confirms an official sales channel.
Is MagO7 Backed by Research?
Yes. Magnesium oxide has clinical support for constipation relief, though no trial tests the MagO7 formula itself. NBPure cites a study in the Journal of Gastroenterology and Motility showing better stool consistency. The detox language is marketing. Reliable evidence covers constipation relief only, not toxin removal. Read the cleanse claims with care.
Does MagO7 actually detox the body? Not in a proven sense. The liver and kidneys handle detoxification. The capsules simply help move stool along.
How Do You Take MagO7?
Adults take three MagO7 capsules at bedtime on an empty stomach. Each dose needs 8 to 12 ounces (240 to 350 ml) of water. The label allows an increase of up to 2 capsules until the desired effect appears. Users then lower the count for maintenance. Serving size varies by person, so start with the standard dose. Timing near bedtime matters most for results.
Dosing Routines:
| Goal | Schedule | Notes |
|---|---|---|
| Targeted cleanse | Nightly for 7 to 10 days | Three capsules at bedtime |
| Daily regularity | Every other night | Supports long-term routine |
| Short-term relief | Nightly as needed | Stop once regular |
| Maintenance | Lower capsule count | Adjust to your body |
Take the capsules 2 to 3 hours after the last meal. Drink plenty of water, at least 8 ounces (240 ml). Now, watch this: the powder version uses half a teaspoon in 8 ounces (240 ml) of water.
How Long Can You Take MagO7?
The label sets a standard cleanse of 7 to 10 days, or until the desired result is reached. The brand also describes an every-other-night routine for daily regularity support. Longer use calls for a doctor’s guidance, because magnesium builds up in people with reduced kidney function. Most buyers finish a single cleanse in well under two weeks total.
A bottle holds 180 capsules, or 60 servings of three. A 10-day cleanse uses 30 capsules. How far does one bottle go? Think of it this way: one bottle covers about six full cleanses.
How Much Does MagO7 Cost?
MagO7 costs $41.95 for a 180-capsule bottle on Amazon as a one-time purchase. The math works out to about $0.23 per capsule. Subscribe and Save lowers the price to $37.75, or $35.66 with the 15 percent savings tier. Prices change often, so check the listing before buying. Larger bundles and the powder version cost more upfront than one bottle alone.
Amazon Price Options:
| Option | Price | Per Capsule |
|---|---|---|
| One-time purchase | $41.95 | $0.23 |
| Subscribe and Save | $37.75 | $0.21 |
| Subscribe and Save, 15% tier | $35.66 | $0.20 |
Is MagO7 Worth the Price?
Yes. MagO7 is worth the price for buyers who want a gentle, predictable overnight option. A 10-day cleanse costs about $6.90 at the one-time price. Generic magnesium oxide costs less per capsule, but those products lack the MagO7 potassium blend and the long track record. Value depends on how often you use it and how well it works for you personally.
Is cheaper always better? Not here. Buyers pay for consistency and a trusted seller. And it gets better: the subscription tiers cut the cost further.
Where Can You Buy MagO7?
Buyers can purchase MagO7 on Amazon, Walmart, iHerb, GNC, and the NBPure website. The Amazon listing ships from Amazon and is sold by NB Pure, LLC. Walmart carries the same 180-capsule bottle with a 4.6 star rating. Direct purchases from NBPure also offer the powder version. Stock and prices vary by store, so check each listing before you order today.
Prices differ by store. Is the cheapest listing always best? Not always. Compare the per-capsule price across stores. Look for the NBPure or NB Pure, LLC seller name. A small check like this protects you from unofficial listings.
