Flat Tummy Tea promises to “kickstart your body”, “support metabolism” and help you “get a flat tummy while you sleep.”

You heard that correctly. So I guess the big question is:

How much should I expect to pay for it?

For starters, Flat Tummy Tea’s price in comparison to their competition is pretty average. They offer a 4-week program at $49.00 and a 2-week program at $36.00. For all that they offer you have to think that’s more than fair, but don’t get me wrong – extravagant claims aren’t results.

So what’s the bottom line?

Here are 5 things you HAVE to check out before buying Flat Tummy Tea.

1, 2, 3, go…

What is Flat Tummy Tea?

Firstly, FlatTummy Tea is a drink kit, designed for detoxification. The kits consists of Activate and Cleanse. The ingredients are:

  • Senna
  • Taraxacum [1] 
  • Galium aparineamellia
  • Camellia sinensis

You’ll drink one glass in the morning and another in the evening. Supposedly, it’ll increase energy expenditure so the body uses more calories, thus reducing weight. Claims also say it can reduce bloating. [2]

Synergy CHC is the company behind FlatTummyTea. The brand was first introduced in 2013. You can buy a two or four-week pack directly from the official website.

It’s also called FT Two and FT Four. One of the newest services is FT Next, a subscription/autoship program. For $45 a month you get four weeks of FT Activate and four servings of Maintain.We like that it contains a few natural ingredients and that it seems affordable, but read on…

Flat Tummy Tea Side Effects – “A Potential Issue?”

The first issue we found with Flat Tummy Tea ingredients was the potential for side effects. “Some of these reports may deal with the interaction of the natural diuretic dandelion and other supplements or prescription medications,” offered up our Research Editor.

One stated, “This one left me constipated. I thought it was supposed to help with that.”

“This tea is terrible, I tried it, and it’s tastes terrible and all it does is give you gas and make you go to the bathroom,” said another user who saw some Flat Tummy Tea side effects.

Not all customers experienced Flat Tummy Tea side effects. “Helped with bloating. Exercising keeps the weight off and eating healthy,” stated a user.

“Started on my day off just in case we had a bathroom issue. No bathroom issues with tummy tea,” commented another.

Flat Tummy Tea Customer Testimonials

Flat Tummy Tea Results – “What Can You Expect?”

Based on customer reviews, FT Four/FT Two results are not exactly what the consumer expected. “Reduced the bloat, but didn’t lose any weight,” commented a customer.

“Those posts online aren’t real. I didn’t lose weight like they did,” commented a customer who saw no Flat Tummy Tea results. [4]

Although there aren’t a lot of Flat Tummy Tea reviews posted, we did locate some customers that have tried the product and saw results. [5]

“Girls do see weight loss results if they pair our tea with a healthy diet and some exercise,” commented a customer.

Through years of research, we’ve found a connection between what seems small, like missing reviews, and a lesser chance of long-term success.

If Flat Tummy Tea is not honest about results and experiences, why would the consumer trust the company or the product?

Is the Flat Tummy Tea Cleanse Proven to Work?

The science side of Flat Tummy Tea is easy. Green tea extract is proven to help with weight-loss, [6] but you can buy that for less than $5 in your local vitamin shop. Other ingredients in the formula are geared toward reducing water [7] and increasing bowel movements.This is not effective means of helping you lose weight.

According to the Journal of American College Health, “Serious medical problems that may occur with laxative abuse include electrolyte and fluid imbalance, structural and functional colonic changes, and allergic reactions.”

The Bottom Line – Does Flat Tummy Tea Work?

Are we brewing up a cup right now? Well, we like the addition of green tea, but that’s not enough to curb our hesitations. We are uncomfortable giving this one our recommendation because using laxatives and diuretics for weight-loss can lead to nasty side effects, based on customer reviews and scientific research.

If you want to lose weight the natural, safe way, we suggest going with a supplement that’s made with clinically tested ingredients that don’t cause potentially harmful side effects.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This one contains four ingredients; clinically-tested with results showing they can help to improve metabolism, suppress hunger and increase fat loss. We’ve read tons of user testimonials explaining some pretty fantastic results.

Plus, they’re so confident that you’ll love the supplement that they’re offering a Special Trial Offer, which is a good sign.

The Flat Tummy Tea program consists of Activate, Cleanse and Maintain. None are particularly strong, in terms of weight-loss. There is one ingredient with some clinical backing, but the official website doesn't bother to share any support. The use of laxatives and diuretics could prove to be an issue, especially for those taking prescription medications.

We dug deep into the Flat Tummy Tea ingredients to give you all of the important facts.

Taraxacum Leaf and Root

Commonly known as dandelion plant, taraxacum leaf and root are used in a number of internal cleansing supplements and herbal tea products. This herb is also found in some traditional medicines to treat upset stomach and gas.

What is it Supposed to Do?

Taraxacum is often used in cleansing and weight-loss products to increase urination. This plant contains some chemicals that boost urine production. This in turn may help with flushing out the kidneys and reducing excess water weight.

Clinical Research

There does not appear to be a solid link between taraxacum and fat loss. A study published in the Journal of Alternative and Complementary Medicine showed that “For the entire population (n = 17) there was a significant (p < 0.05) increase in the frequency of urination in the 5-hour period after the first dose.” [1] But, since this herb is a diuretic, it can lead to dehydration.

Senna Leaf and Pods

Senna is an herb that has been used for many years to treat constipation. Both the fruit and leaves of this plant are used to make some traditional medicine. Like many herbs, this ingredient is found in a number of diet pills and weight-loss teas.

What is it Supposed to Do?

The key component found in senna leaves and pods is sennosides. These chemicals basically irritate the lining of the intestines. This in turn causes a laxative effect. Therefore, this herb may help with internal cleansing, regularity and even reduce bloating.

Clinical Research

According to WebMD, “Taking senna by mouth is effective for short-term treatment of constipation. Senna is an FDA-approved nonprescription drug for adults and children ages 2 years and older.” However, this herb has not been proven to aid with weight-loss.

Galium Aparine

Sometimes referred to as cleavers, scarthgrass or bedstraw, galium aparine is an herb that contains chemicals called tannins. It has been used for centuries to treat conditions such as painful urination and fluid retention.

What is it Supposed to Do?

Some herbal cleansing teas and weight-loss supplements contain galium aparine to help promote urine flow and reduce retained water weight. It may also help with irritable bowel syndrome and flushing out the lymphatic system.

Clinical Research

Unfortunately we did not find a correlation between galium aparine and weight reduction. However, Cleavers have been “used to relieve edema and to promote urine formation during bladder infections,” according to the University of Michigan. [2]

There are several ingredients out there with clinical backing. The trouble is many companies fail to put more than one in a supplement at a time. Dietspotlight Burn offers four in one formula.

Flat Tummy Tea Side Effects:

Choosing a natural weight-loss supplement seems like it would come without side effects. However, even natural formulas may cause a negative reaction in some users. Even though Flat Tummy Tea side effects are rare, some users still experience them.


Bloating is a feeling of gassiness and stomach discomfort. It may become severe and cause distension or swelling of the abdomen.

What causes bloating?

The main cause of bloating is overeating or what you eat. It may also be caused by eating too fast or eating rich and fatty foods. Fat doesn’t digest as fast as carbohydrates or proteins, which means it makes you feel full longer. [1]


Feeling unbalanced or lightheaded means you may be dizzy. It may even make you feel like you’re going to faint.

What causes dizziness?

While dizziness may be caused by a number of different things, the most common causes include:

  • Migraines
  • Medications
  • Alcohol or drugs
  • Inner ear problems
  • Vertigo


Headaches are rather self-explanatory, but they come in a variety of types. Any continuous pain felt in your head may be described as a headache.

What causes headaches?

Headaches can be caused by a number of different factors. Most commonly, a headache anxiety, noise, hormones changes, sensitivity to food or even exercise.


When a bowel movement produces a loose, liquid discharge, it’s known as diarrhea. It’s actually stool that hasn’t remained in your system long enough for the colon to absorb the liquid portion. It will come out of your system very quickly and may cause multiple bowel movements in a very short time.

What causes diarrhea?

Most commonly, diarrhea will clear up on its’ own. [2] However, it may be caused by an inflamed bowel or a bacterial or viral infection. Diarrhea can also be a reaction to something you ate or a stressful event.

Flat Tummy Tea is not guaranteed to cause side effects. While bloating, dizziness, headaches, blood in stool and diarrhea have all been reported, along with others, not all users will experience problems. It’s always a good idea to speak with your physician before taking any supplement, especially if you’re under the age of 18, on prescription drugs currently, pregnant, nursing or have any type of medical condition.

Some of these side effects are associated with teas like this and, though rare, there is a chance. If you’re looking for a different option, we like Dietspotlight Burn because the ingredients are there and there’s not too much caffeine.


When taking a supplement like Flat Bunny Tea, side effects aren’t always guaranteed. But, in this case, we looked for user comments to show you the side effects they experienced.

Flat Tummy Tea Scientific Abstracts:

Peppermint Leaf

Essential oils of the peppermint leaf are used in traditional medicines. The phenolic properties of the leaves include several flavanoids, luteolin, hesperidin, primarily eriocitrin, and rosmarinic acid. Peppermint has shown significant antimicrobial and antiviral properties in vitro, as well as high antitumor and antioxidant actions. There are an array of trials reported which examine the effects of peppermint oil on IBS (irritable bowel syndrome). At the same time, there are few human studies of peppermint leaf and no clinical trials. [1]

Fennel Seed

Analysis of data shows the efficacy of fennel in multiple in vitro and in vivo pharmacological properties such as antiviral, antimicrobial, antimutagenic, anti-inflammatory, antipyretic, cardiovascular, apoptotic, antispasmodic, antinociceptive, antithrombotic, chemo modulatory, antitumor, hepatoprotective, hypolipidemic, hypoglycemic, and memory enhancing properties. Foeniculum vulgare (fennel) has risen in notoriety as a good source of traditional medicine as well as delivering a noteworthy basis in pharmaceutical biology for the creation of new drugs and use in future clinical trials. [2]

Coriander Seed

Coriander possesses an essential oil (0.03-2.6%). It’s used as a spasmolytic, stomachic, and carminative which have higher bioactive properties. Various sections of the plant (seeds, leaves, flowers, and fruit) showcase antioxidant activity as well as anticonvulsant, sedative-hypnotic, diuretic, anti-diabetic, anti-mutagenic, anti-microbial, and anthelmintic activities. Coriander is rich in antioxidants and could have the ability to delay the onset of a variety of age-related diseases. It is concluded that urgency be shown in an effort to explore the roles of these compounds.[3]

Dandelion Root

Studies have shown T. Officinale(dandelion) to increase urinary frequency. For all the participants involved (n = 17) there was a substantial increase (p < 0.05) in the frequency of urination for 5 hours following the first dose. There was also a significant increase (p < 0.001) in the excretion ratio within the period of 5 hours following the second dose. In conclusion, based on the data compiled from the human trials, ethanolic dandelion extracts show extreme promise as a diuretic in humans. [4]

Caraway Seed

Results suggest that cold-pressed black caraway may serve as a dietary source of antioxidant for the promotional of health and prevention of disease. Cold-pressed black caraway seed oil may be used in foods as a natural antioxidant, to improve quality. [5]

Lemon Grass

Lemon Grass essential oil (LGEO) showed promising antifungal effects against C. tropicalis, Candida albicans, and Aspergillus niger with different IZDs (inhibition zone diameters) (35–90 mm). For evaluating the anti-inflammatory effects, lemon grass essential oil (10 mg/kg, administered orally) significantly reduced carrageenan-induced paw edema with similar results to that reported for oral diclofenac (50 mg/kg). In conclusion, it has been indicated that lemon grass essential oils have a stunning potential for the development of drugs for fungal infection treatment and skin inflammation. [6]

Is there caffeine in the tea?

Richard (Editor)

Hi Caitlyn. Flat Tummy Tea doesn’t specifically contain caffeine; green tea does contain caffeine.

Breast milk interactions

Can you drink this tea while breast feeding?

Victoria (Editor)

Hi! The warning label for Flat Tummy Tea says “Do not use when pregnant or breastfeeding.”


I’m already the skinny type… so i am not into losing more weight… i just want a flat tommy… anybody know if it will work for me?

Made for both sexes?

Wanted to know if this product is also for men and if not do you have one that is?

Cant find it
YourThomas Name

Where can I order this tea? I need to loss weight


Hi Thomas! Sorry that we’re not affiliated with the company. Flat Tummy Tea is available online and ships to the U.S.

Belinda (Verified User)

worried. My Thyroid was removed. since taking the tea my eyes seem to be popping. Thinking taking the tea with thyroiid supplements may not be a good thing. If possible, please give advice.

Victoria (Editor)

Hey Belinda. Thyroid medications, like Synthyroid can cause all kinds of issues when taken with supplements. We have not found a direct connection between Flat Tummy Tea and bulging eyes.

What’s interesting is that this is a symptom of a goiter, but you can’t have a goiter if your thyroid is removed.

Did you stop using Flat Tummy Tea? If so, did the reaction stop?


oh no!!!! I take 50 mg of Synthroid every day and I just ordered this, should I not take it??

Not sure how to use it

Is it OK to also pour the leaves in your cup and drink it?????

Maribel (Editor)

Hi. Yes, its okay. It should steep in a cup of hot water for 5-7 minutes before drinking. One teaspoon of tea is needed to make a single serving. You also need to consume one cup of the Cleanse Tea every other night before going to sleep.

If you’re looking for a product with simpler instructions, you might want to check out Dietspotlight Burn.


yes it is. I make my tea in a small pot. Boil the water & put in the tea. The more it boils, the tea will go to the bottom. When you pour it into the cup, the leaves stays in the bottom. Or use a spoon when pouring it to stop the leaves


Seeing all of these negative reviews makes me scared to try it. I just got it yesterday and today I was going to start


Too many horrible results,I have purchase some but don’t think I will be using it.

Itching side effect
DEE DEE (Verified User)

I’ve been using the tea for 2 days and I have what appears to be a break out…my body is itching all over?? Has anyone had this type of reaction?


Yes I’m itching like crazy right now and I just started 2 days ago


Hello Dee Dee. This sounds a lot like an allergic reaction. As you can tell from Tricia’s response, others have had this experience too. Did the itching stop when you stopped using Flat Tummy Tea?

Hopefully it helps me

I want to wear dresses cause my problem is my stomach, lets see if it works.


Day one today, and I can tell you that I wasn’t feeling well and just did the one for breakfast and been drinking fluids nonstop.


I started flat tummy tea last week, and I followdled all the instruction but instruction keep getting severe nausea and dry heaves. Almost puking, this has happened twice now. None else have that?

Victoria (Editor)

Hi. It’s not unheard of to feel nauseous when taking a laxative – like the one in Flat Tummy Tea cleanse. The ingredients just don’t settle with everyone.

Did you stop using the tea and did that help?

Irma Ramos

Hello.. my husband yesterday he drink a cup of evening tea.. today he feels [bad]. he takes every morning a blood pleasure pill. No I’m so worry if he stomach ache is related form the tea.?

Victoria (Editor)

Hi Irma. We’ve not heard about an interaction between Flat Tummy Tea ingredients and a blood pressure pill, but supplements aren’t tested like medications. His doctor will want to see the label to make sure there are no interactions.

Let us know if we can help with anything Irma.


I do 50 sit ups everyday but my tummy still looks bloated. So i was really excited to try this product. It’s my third day and so far all it does is give me excess gas and make me pee every 15 minutes. well, atleast I see a slight decrease in my stomach. But I’m not sure which is better; having a sightly flatter tummy with a farty pants or a bloated stomach. hmm…

Kristen Cooley

Flat tummy tea made me constipated for over 5 days! It has been a month since I tried it and my bowl movements have been terrible since wasting money on this product!


I’m currently in he’d with a piercing headache and very loose stools. I haven’t been able to keep anything in my body besides (barely) water. I’ve been drinking flat tummy tea for almost a week now and at first it was okay but now I feel like crap and there’s no other explanation for this. I feel like I’m about to implode and I just want the pain to end!!!


The flat tummy tea give me a sore throat for days.


i tried seeing if I could return this product because I literally drank the tea early in the morning and then went to the gym a couple hours later and was on the toilet for a good 15 minutes *before my workout and then 15 minutes *after my workout. My stomach was hurting so bad and I was having abdominal pain. They wouldn’t let me return it due to how I had already opened it and used it *once. how the heck are you supposed to know ahead of time how you’re going to react to this product and then spend 50 dollars on something that just makes you in pain


I tried this tea for the first time yesterday on my birthday and I already see the problem. I still have my wisdom teeth in and it irritated and swollen up my left side of my face. Very upset about that, I took NyQuil to clear it up but the tea also makes you gassy and sleepy.

Ieshia mahmud

I did feel an increase in my energy, but the tea started making me more bloated and gassy than normal so I stopped and it appears my body is retuning to normal. I will just start drinking green tea and plenty of water


Just because you see these celeb’s out there saying how good this product is and they use it just remember they are getting paid to say that. I tried this product and it constipated me and gave me the worse cramps and bloating. Thought it was suppose to do the opposite. I stopped using it after a week and I was back to normal. And they want give you your money back. Horrible product and horrible customer service. Think twice before you order.


Just started it yesterday and I can say it was alright. Yes it gives you almost contraction pains and sends you to the bathroom. But I was expecting this as it is cleaning out my insides. Good in taste as well. This tea reminds me of a cheaper supermarket tea called ” Te Manasul.”


After 1 day I have really bad body aches and I am so tired I dont have the energy to workout. Day 2 same result. I slept for 10hours and still took a 1.5 hour nap today. I can admit I’m not drinking as many liquids as I need to. Maybe I will try that.


Since my sister has ordered the tea its been 8 weeks we haven’t receive the tea up to now…


I should have researched first and read the reviews before I ordered this tea. My order was in November its December now still no tea and no response from company.

Your Namecynthia

Ordered the tea and did not get it…..MAD AS HELL


I only use a pinch of tea, and I have a headache and wanna sleep smh


I got a headache too and this is my first time using it


Makes me dizzy and bad headache after 2 days


I have been taking FTT for over 1 month now and have just ordered my 2nd 4 week pack. I have had reasonable results but mostly seen a massive change in my skin. Much clearer and smoother. I do got to the bathroom a couple of times in the morning and I am definitely more regular but no bad side effects at al. Occasionally I am a little dehydrated but I do try to drink at least 2.5 litres of water to elejminate that. Overall I am happy with this tea and will continue with the FTT Next which is the product you purchase for the 2nd and ongoing months.


First day of use and felt very dizzy, had cold chills and my body temperature was extremely HOT!! Not yo mention the sleepiness that I couldn’t shake. The tea was the only new thing that I’ve tried so it has to be what’s causing my symptoms.


I have been drinking the flat tummy tea for 2 days now and I have been constipated. I have headache anytime I drink it and I feel cramps in my abdomen


i have been on this tea for a Month now bt there is no changes instead m gaining weight…guys this is a waiste of Money nd time
