BellyFlush (Belly Flush) is a 2-capsule nightly herbal cleanse from Simple Promise™, sold to adults who feel bloated, backed up or “sluggish.” Below we explain all 11 ingredients in plain English, what it really does (it contains three laxative herbs), today's verified prices, the 365-day guarantee, and the safety questions to ask your doctor first — in large print and without the hype.

BellyFlush™ is a dietary supplement from Simple Promise™, a US supplement company whose motto is “We Follow the Science.” The bottle describes it as a Detox and Cleanse, Gut and Colon Support formula that reduces occasional bloating.* Each bottle contains 60 capsules — a 30-day supply at 2 capsules a day.
The formula combines 11 herbs and minerals in three blends that the company calls a “3-Phase Gentle Cleansing System”: a Body Cleanse Blend (590 mg), a Digestion Support Blend (230 mg) and a Detox & Gut Health Blend (300 mg).
Here's what most sales pages won't spell out: the Body Cleanse Blend contains senna, cascara sagrada and cape aloe — three herbs that work as stimulant laxatives. That's why customers describe BellyFlush as something that “empties you out.” The other eight ingredients are mostly soothing and traditional digestive herbs meant to make that cleanse more comfortable.*
Understanding this one fact helps you use BellyFlush wisely: it can be a helpful short-term option when you feel backed up and bloated, but it isn't designed to be a forever supplement, and it isn't a weight-loss product.
Digestion often slows down after 50. Less activity, less water, lower-fiber meals and many common medications can all leave you feeling bloated and irregular. Here's an honest look at who BellyFlush fits.
See your doctor if you notice blood in your stool, black or tarry stools, unexplained weight loss, a change in bowel habits lasting more than 2 weeks, or severe or ongoing belly pain. These can be signs of conditions that need medical care. US guidelines also recommend colorectal cancer screening for adults 45 to 75 — ask your doctor if you're due.
Simple Promise™ groups the 11 ingredients into three blends. Here's what each one is designed to do, in plain English.*
Cascara sagrada, cape aloe, senna leaf extract and triphala fruit. Senna, cascara and aloe are stimulant laxatives that prompt the bowel to move — this is the part that does the “flushing.”
Fennel seed, a traditional remedy for gas and bloating,* and bentonite clay, which the manufacturer describes as a binder.
Marshmallow root, licorice root extract, slippery elm bark, cayenne and milk thistle — mostly soothing, coating and traditional herbs meant to make the cleanse more comfortable.*
What to realistically expect: Because of the laxative herbs, most people can expect a bowel movement the next morning after an evening dose, sometimes with cramping or loose stools. Feeling “lighter” afterward is mostly the result of emptying the bowel — it is not fat loss.
According to the Supplement Facts label, a serving is 2 capsules and contains three proprietary blends totaling 1,120 mg. Here's every ingredient, what it's traditionally used for, and what to watch out for.
Senna is one of the best-known herbal laxatives and is the active ingredient in many drugstore laxatives. It contains compounds called sennosides (the label says the extract is standardized to 20% sennosides) that stimulate the bowel to move. It works, but it isn't meant for long-term daily use: over-the-counter senna labels say not to use it for more than 1 week without a doctor's advice.
Cascara sagrada is the bark of a North American buckthorn tree, traditionally used as a laxative. In 2002 the FDA ruled that cascara sagrada is not generally recognized as safe and effective as an over-the-counter laxative drug ingredient, citing inadequate safety data. It can still be sold in dietary supplements.
Cape aloe is the dried leaf latex of a South African aloe species, a strong traditional laxative. Like cascara, aloe was removed from over-the-counter laxative drug products by the FDA in 2002 because there wasn't enough safety data. This is a different part of the plant than the soothing aloe gel used on skin.
Triphala is a traditional Ayurvedic formula usually made from three fruits. BellyFlush's label lists Terminalia bellirica (bibhitaki), one of the three. It has a long history of use for regularity; modern human research is limited.
Fennel is a familiar kitchen spice that has been used for generations after meals to ease gas and bloating. It's a gentle ingredient, but people allergic to celery, carrot or mugwort may react to it.
Bentonite is a natural clay that can bind substances in the gut; the manufacturer calls it a “toxin binder.” Because a clay can also bind other things you swallow, ask your pharmacist whether to take BellyFlush at a different time from your medications.
Marshmallow root contains mucilage, a gel-like fiber that coats and soothes. It's traditionally used to calm an irritated digestive tract and is generally well tolerated.
Slippery elm is another mucilage-rich herb traditionally used to coat and comfort the digestive tract. Its coating effect may also slow the absorption of medicines taken at the same time.
Licorice root has long been used for stomach comfort. The label says this extract is standardized to 6% glycyrrhizin acid. The NIH notes that glycyrrhizin can raise blood pressure and lower potassium, and that even small amounts have been linked to severe effects in people with high blood pressure or heart or kidney conditions.
Cayenne (40,000 heat units, per the label) is included by the manufacturer for “circulation support.” In some people, hot pepper can aggravate heartburn or an upset stomach.
Milk thistle is best known as a traditional liver herb. According to the NIH, the most common side effects are digestive (bloating, nausea, gas), and it may cause allergic reactions in people allergic to ragweed, chrysanthemum, marigold or daisy.
BellyFlush lists only the total weight of each blend, not the amount of each herb. That's legal and common, but it means you can't see how much senna, cascara, aloe or licorice is in each serving. If you have a health condition or take medication, bring the label to your doctor or pharmacist, and ask Simple Promise™ support (1-800-259-9522) if you need more detail.
BellyFlush itself has not been tested in a published clinical trial. Here's what independent sources say about its most important ingredients.
| Ingredient | What it's known for | Evidence & status |
|---|---|---|
| Senna | Stimulant laxative used in many over-the-counter constipation products. Labels advise no more than 1 week of use without a doctor's advice. | Well-established laxative |
| Cascara sagrada | Traditional stimulant laxative. The FDA ruled in 2002 that it is not generally recognized as safe and effective in OTC laxative drugs, citing inadequate safety data. Federal Register | Safety data limited |
| Cape aloe | Traditional stimulant laxative (leaf latex). Included in the same 2002 FDA ruling as cascara. | Safety data limited |
| Licorice root | Traditional stomach herb. Glycyrrhizin can raise blood pressure and lower potassium. NIH NCCIH | Use caution |
| Fennel, marshmallow, slippery elm | Traditional remedies for gas, bloating and an irritated gut.* | Mostly traditional use |
| Milk thistle | Traditional liver herb; the NIH says there isn't enough high-quality evidence for firm conclusions. NIH NCCIH | Limited evidence |
| Triphala, bentonite, cayenne | Traditional or supporting ingredients with limited human research for digestion. | Limited data |
Most healthy adults can use an herbal laxative for a few days without problems. The concerns come with long-term use, certain medications, and certain health conditions — all more common after 50.
Drink plenty of water, and stop if side effects are bothersome.
BellyFlush is sold as a 30-day supply, but its main active herbs are stimulant laxatives. Over-the-counter senna labels say not to use senna for longer than 1 week without the advice of a healthcare provider. Long-term use of stimulant laxatives can lead to electrolyte imbalance (such as low potassium) and can make the bowel rely on them. If you'd like to take BellyFlush for longer than a week, ask your doctor first. More in our BellyFlush side effects guide.
| If you take or have… | Why it matters |
|---|---|
| Diuretics (water pills) | Both diuretics and stimulant laxatives can lower potassium; licorice can lower it further. |
| Digoxin or heart-rhythm medicine | Low potassium can increase the risk of heart-rhythm problems with these medicines. |
| Corticosteroids (e.g., prednisone) | The NIH notes reported interactions between licorice and corticosteroids. |
| High blood pressure, heart or kidney disease | Licorice's glycyrrhizin can raise blood pressure; the NIH warns of severe effects in these groups. |
| Any daily prescription | Laxatives speed things through the gut, and clay or slippery elm may bind or slow absorption of other medicines. Ask your pharmacist about timing. |
| Ragweed or daisy allergy | Milk thistle may cause allergic reactions in people allergic to related plants (NIH). |
| Pregnancy, nursing, under 18 | Not recommended; the manufacturer says it is not for people under 18. |
The official directions are: take two (2) capsules 20–30 minutes before bed with an 8 oz. glass of water, or as recommended by your healthcare provider. Do not exceed the recommended serving size.
Habits that help regularity long term: fiber-rich foods (beans, oats, fruit, vegetables), 6–8 glasses of fluid a day, a daily walk, and not ignoring the urge to go. If constipation keeps coming back, your doctor can check for causes such as medications, thyroid problems or other conditions.
6 bottles $198 ($33 each) with free US shipping · 3 bottles $147 · 1 bottle $59
Every package is backed by Simple Promise™'s 365-day, 100% money-back guarantee.
Bottom line: BellyFlush is a well-packaged herbal laxative-and-comfort formula from a real US company, with a full ingredient list and an unusually long 365-day guarantee. It's likely to do what it says — help you go — but it's best for short-term use, its doses are hidden in proprietary blends, and several of its herbs need extra caution for adults over 50.
Prices checked on the official site on October 5, 2026. Each bottle holds 60 capsules, a 30-day supply. One-time purchase — confirm the total at checkout.
Cost per day and savings are our calculations, based on 2 capsules a day and the single-bottle price of $59. Prices and shipping are set by the manufacturer and can change. The Simple Promise™ store also offers a separate Subscribe & Save plan; read the order summary before paying so you know whether you chose a one-time order or a subscription.
Our buying advice: Because BellyFlush is best used short-term, most people should start with 1 bottle. A bottle used for occasional relief can last well beyond 30 days. Only consider the 3- or 6-bottle packages if you already know BellyFlush agrees with you and your doctor is comfortable with how often you'll use it.
Simple Promise™ backs BellyFlush with a 365-day, 100% money-back guarantee. That's far longer than the 30 to 90 days common in the supplement industry, and it gives you a full year to decide whether BellyFlush is right for you.
Tip: Order through the official site. Products bought from unauthorized resellers may not be covered by the manufacturer's guarantee.
The Simple Promise™ store showed 122 customer reviews for BellyFlush when we checked on October 5, 2026. The manufacturer also publishes customer stories like this one from “Lucy Rose”:
“I tried this and took 2 at bedtime and drunk plenty of water during the day and maaaaan it really empties you out.”
That comment matches what you'd expect from a formula with senna, cascara and aloe: a strong, next-morning laxative effect. It's also a good reminder to start on a day you're at home and to drink plenty of water.
Please note: Reviews and testimonials shown on the manufacturer's store are published by the seller and haven't been independently verified by us. Individual experiences are not typical or guaranteed results. We do not publish star ratings we can't verify.
No. Some marketing says you may feel “lighter, tighter and slimmer.” Emptying your bowel and reducing bloating can make your belly feel flatter, but the scale change is stool and water, not body fat. For lasting weight management, talk to your doctor about diet and activity.
For ongoing constipation, doctors often start with more fiber (food or a psyllium supplement), more fluids and more activity, and may suggest gentler over-the-counter products. A short herbal cleanse like BellyFlush may fit occasional use; your doctor can help you decide.
If you're an otherwise healthy adult who deals with occasional constipation and bloating, BellyFlush is a credible short-term option. Its senna, cascara and aloe give it a real laxative effect, its soothing herbs aim to make that gentler,* and Simple Promise™'s 365-day money-back guarantee takes most of the financial risk out of trying it.
It's not for everyone. Stimulant laxatives aren't meant to be taken every day for months without medical advice, the individual doses are hidden in proprietary blends, and licorice is a real concern if you have high blood pressure, heart or kidney disease, or take diuretics or steroids.
Our recommendation: talk to your doctor, start with one bottle, use it for occasional relief rather than as a daily habit, and keep the guarantee details handy.

Straight answers to the questions readers ask most. Updated October 5, 2026.
BellyFlush™ is an herbal colon-cleanse and digestive-comfort supplement made by Simple Promise™. Each serving of 2 capsules contains 11 botanicals and minerals in three blends, including senna, cascara sagrada and cape aloe (herbs that act as stimulant laxatives), plus fennel, marshmallow root, slippery elm, licorice, triphala, bentonite clay, milk thistle and cayenne. A bottle holds 60 capsules, a 30-day supply.
BellyFlush contains senna, cascara sagrada and cape aloe, herbs that are well known for their laxative effect, so many people can expect a bowel movement after taking it. The finished BellyFlush formula itself has not been tested in a published clinical trial, and its doses are listed only as blend totals, so we can't tell you how strong each ingredient is. Results vary.
The official directions are two (2) capsules 20–30 minutes before bed with an 8 oz. glass of water, or as recommended by your healthcare provider. Do not exceed the recommended serving. Drink plenty of water during the day.
Because BellyFlush contains stimulant laxative herbs, ask your doctor before using it for more than about a week. Over-the-counter senna labels say not to use senna for longer than 1 week without the advice of a healthcare provider, and long-term use of stimulant laxatives can cause electrolyte imbalance and make the bowels rely on them.
It can be, with your doctor's OK. Adults over 50 are more likely to take medicines that interact with laxative herbs or licorice, such as water pills (diuretics), heart-rhythm medicines like digoxin, corticosteroids and blood pressure medicines. Licorice root can raise blood pressure and lower potassium, according to the NIH. Show your doctor or pharmacist the Supplement Facts label before you start.
Stimulant laxative herbs commonly cause loose stools, stomach cramps and urgency, especially in the first few days. Long-term use can lower potassium and other electrolytes. Licorice can raise blood pressure, and milk thistle can cause allergic reactions in people allergic to ragweed or daisies. Stop and call your doctor if you have severe pain, rectal bleeding, dizziness, muscle cramps or an irregular heartbeat.
No. Emptying your bowels can make you feel lighter and less bloated, but the weight you lose that way is stool and water, not body fat. BellyFlush is not a weight-loss treatment.
As checked on October 5, 2026: 1 bottle is $59, 3 bottles are $49 each ($147 total), and 6 bottles are $33 each ($198 total). The 6-bottle package includes free US shipping. Shipping for smaller packages is shown at checkout.
