Flat Tummy Tea Review

Flat Tummy Tea claims to be an all natural and a gentle remedy to your body when you are said to be feeling bloated and sluggish. The official website says that this product can speed up your metabolism, cleanse your system and improve digestion, reduce bloating and may boost your energy levels. This supposedly makes you feel better and look better. However, some of the ingredients in these products may have possible laxative and diuretic properties and might contain some caffeine, which could cause side effects in people that are sensitive to stimulants.

Claimed weight loss benefits

Flat Tummy Tea markets itself as a herbal detox tea, which may help to cleanse your system, speed up your metabolism, reduce bloating and boost your energy levels. It directly claims to improve your metabolism that may help ‘flatten that tummy.’ Clinical studies on the ingredients contained in the Activate tea and Cleanse tea suggest that the product may act as an appetite suppressant. A simple diet plan is given on the official website and contains their top tips for how they claim you can get an even flatter stomach during your detox. However, it is not as thorough as you may find elsewhere.

How Flat Tummy Tea Works


Flat Tummy tea is marketed as a two-step herbal tea detox that comes in two or four week packs. The official website claims that their Activate tea will help you increase your metabolism, give you an energy boost and get your digestion ready to start the day, supposedly leading to a flat stomach. Step two is the Cleanse tea, which they say detoxifies your intestinal track and claims to get rid of toxins and reduce water weight. This is supposedly to keep you flat stomach. They also say that most women that use the product start to feel a difference within the first few days.

Taraxacum Leaf and Root

Taraxacum is used in the Activate tea and the Cleanse tea. Perhaps this ingredient is best known as dandelion, which is said to be rich in minerals and vitamins. It is a herb that can supposedly reduce fat absorption and break down fat. It is claimed to also act as a possible diuretic and laxative, which may reduce bloating but might only lower your weight on the scales temporarily.

Galium Aparine

Galium aparine is contained in the Activate tea, which may be more commonly known under the names of cleavers, clivers, goose grass or sticky willow. It is a herb that people claim to use to make medicine, being said to increase urine flow to relive fluid retention. It could temporarily reduce your weight on the scale, but no studies link it to permanent weight loss.

Camellia Sinensis

Green and black teas are said to come from the same evergreen plant, Camellia sinensis. Present in the ingredients of Activate tea, it is claimed to have a high level of antioxidants and caffeine, which may aid weight loss by potentially increasing your metabolism. This may burn more calories. The caffeine may also improve your energy levels, which could help you to perform better during exercise.


Commonly known as figworts, this ingredient is contained in the Activate tea. It is a herb, which is apparently used to make medicine. It is supposedly used as a heart stimulant, laxative and diuretic. However, no evidence could be found to find a connection between possible weight loss and scrophularia.

Glycyrrhiza Glabra

Glycyrrhiza glabra is supposedly a genus in the legume family and may be best known for forming liquorice. It is contained in the Activate tea and the Cleanse tea. It may act as a mild laxative. A few studies claim it could act as an aid in weight loss by supposedly lowering abdominal fat and having hypoglycaemic effects.

Mentha x piperita

This is used in both the Activate tea and the Cleanse tea. It may be more commonly known as peppermint. A study claimed it could potentially improve your performance during exercise. This might mean you work harder during your workout and burn more calories.

Carum Carvi

Carum carvi is contained in both the Activate tea and the Cleanse tea. It is said to contain antioxidants and many people claim it has healing powers. It is supposedly used for digestive problems such as heartburn, bloating and relieve constipation. Carum carvi is claimed to be helpful in the management of obesity because of its bioactive constituents.

Melissa Officinalis

Melissa Offcinalis is contained in the Activate tea and Cleanse tea. It is supposedly known more commonly as lemon balm and has been linked to potentially helping to regulate body weight and lipid metabolism.

Foeniculum vulgare

Perhaps better known as fennel, foeniculum vulgare is present in both the Activate tea and the Cleanse tea. It has been said to have the potential to help you decrease your food intake, which may help you regulate your diet. Thus, this could mean decreasing body weight.

Senna Alexandrina pods and leaf

Senna is a herb, which is contained in the Cleanse tea. There is insufficient evidence to suggest that it can be used to burn fat or properly aid in weight loss. It is claimed to have laxative qualities, which may be why it is used as medicine for constipation, irritable bowel syndrome and haemorrhoids. As it may flush out your system, Senna might only result in temporary weight loss.

Rheum Rhabarbarum

The Cleanse tea contains Rheum Rhabarbarum, which you may know as rhubarb. A study indicated that it might be useful in reducing body weight, as it seems to be effective in rats that were fed a high fat diet when it was contained in a dietary herbal formulation. More studies will be needed to prove its effectiveness on its own.

Key Flat Tummy Tea Ingredients


Flat Tummy Tea is a loose-leaf tea blend. The official website claims that Flat Tummy Tea is made from 100% natural and earth grown herb ingredients, which are all supposedly safe and a gentle way to flatten your stomach. Although these ingredients are freely given on their website, no amounts are specified. Most of the active ingredients have undergone clinical trials claiming their possible health benefits and potential use in weight management; however, these are by no means conclusive.

Taraxacum Leaf and Root

Dandelion is apparently used medicinally to treat bladder infections, gallstones, intestinal gas and constipation. This may be down to its diuretic effect, although, research has not proven its effectiveness in these treatments. It has supposedly become popular in weight loss supplements due to its potential in reducing bloating and may even reduce fat absorption. It may only reduce your weight on the scales temporarily because of possibly being a diuretic and laxative.

Camellia Sinesis

As it contains caffeine, Camellia sinensis may help in the weight loss process through the process of thermogenesis. This heats up the body and could help you to burn more calories. The caffeine may also suppress your appetite and could act as an energy enhancer. Green tea is made from camellia sinesis and has become a popular weight loss supplement, due to its potential thermogenic properties.

Glycyrrhiza Glabra

The Liquorice root is claimed to be used for several digestive system complaints, such as stomach ulcers, heartburn and chronic gastritis. Also, It is perhaps known for being a possible flavouring in food, beverages and tobacco. It has become an ingredient in many health supplements due to its claimed benefits for weight loss, supposedly lowering abdominal fat, in particular.

Melissa Officinalis

Lemon balm is said to be a perennial herb from the mint family and are supposedly used to make medicine for digestive problems, such as heartburn, bloating, loss of appetite and stomach ache. It is a plant, which many people claims to have a healing power. It may be able to help regulate body weight.

Foeniculum vulgare

Fennel is a herb that is believed to be an alternative medicine for indigestion, bloating and even bronchitis. Its potential to help you decrease food intake may act an aid in weight loss and could be used to decrease the amount of calories you consume. Thus, you may be able to eat less that you have burned that day to lose weight.

Rheum Rhabarbarum

Rhubarb is a plant, which is claimed to be used in traditional Chinese medicine, such as for constipation, heartburn, gastrointestinal bleeding and stomach pain. Although, strong clinical evidence to its effectiveness are lacking. It may also have the ability to help in weight management.

Clinical Studies

Clinical Researcher 538

Clinical studies are a very important stage for testing the effectiveness of a product or its ingredient and to ensure that it is safe for human consumption. The official website claims that Flat Tummy Tea has had years of testing, trialling and researching. However, there is no information provided to prove this. Therefore, there seems to be no clinical studies performed on Flat Tummy Tea as a whole that are freely available. There have been some studies conducted on the ingredients, which may help us to reach a conclusion on the product’s effectiveness and safety.

Taraxacum leaf and root

A study on Taraxacum officinale investigated whether its leaves and root could have antioxidant properties and a hypolipidemic effect. This is having the ability to lower lipids, which are fatty acids. The study was conducted by analysing rabbits fed a high cholesterol diet and that were split into four different diet groups; a normal diet, high cholesterol diet, high cholesterol diet with 1% of dandelion leaf and a high cholesterol diet with 1% dandelion root. It was found that the rabbits given the leaves and root positively changed lipid profiles and it improved antioxidant enzyme activity. This means that this ingredient could aid weight loss in humans. Further studies will be needed to test its effectiveness.

Galium aparine

While galium aparine is claimed to be used as a diuretic and may increase urine flow to relive fluid retention, there are no reliable studies to back up these claims. There are also no clinical studies linking galium aparine to permanent fat loss.

Camellia Sinesis

Studies on green tea indicate its potential effectiveness for weight loss. One study found that the catechins in green tea could help you to lose weight because of the process of thermogenesis. However, other studies have found that its effectiveness remains unclear and that it may only induce a small, non-significant weight loss in overweight or obese adults.

Glycyrrhiza Glabra

One study looked at the effect of liquorice extract on diabetes-induced rats. They found that daily ingestion of the extract for 60 days reversed the adverse effect of diabetes on the rats. They claimed that it attenuated body-weight loss. Another study looked at the root of the glycyrrhiza species (liquorice) and its possible effect on abdominal fat accumulation and blood glucose levels in diabetic and obese mice. It found that it may have abdominal fat lowering and hypoglycaemic effects.

Mentha x piperita

One study investigated the effects of peppermint on exercise performance in 12 healthy male students. Each was given one 500ml bottle of mineral water containing 0.05ml of peppermint essential oil for ten days. The results claimed that there was enhancement in the respiratory efficiency and energy expenditure during the exercise. Both resting and exercise heart rates seemed to have significantly decreased. This may mean better exercise to burn fat and aid in weight loss.

Carum carvi

One study looked at the effect of carum carvi on weight, serum glucose and lipid profile in diabetic rats. They were divided into three groups; normal, diabetic and diabetic that were to be treated with caraway. They were monitored for three weeks. 1g/kg body weight of caraway was given orally on a daily basis. The results found that the caraway caused a significant decrease in blood glucose level, alleviated body weight loss and decreased total cholesterol. It concluded that caraway may have anti hyperglycaemic and hypolipidemic activity in diabetic rats. Further studies will be needed to see if this potential effect occurs in humans.

Melissa Officinalis

One study looked at Ob-X, which is a mixture of three herbs, one of them being melissa officinalis. Mice were fed a high fat diet for 12 weeks and they gained body weight compared with mice fed a low fat diet. But when these high fat diet mice were supplemented with Ob-X, they showed a decrease in circulating levels of triglycerides and total cholesterol and it inhibited hepatic lipid accumulation. They believed that these findings demonstrated that Ob-X could regulate body weight and lipid metabolism.

Foeniculum vulgare

One study claimed that hot temperament herbs, such as fennel, could be useful for weight control.The study involved evaluating the effects of diets containing some hot and cold temperament herb seeds in rats in acute (24 hours) and sub-acute (7 days) experiments. Fennel was included as one of the herb seeds in the hot category. The study found that in the acute experiment, the fennel fed group showed a significant decrease in food intake. In the sub-acute experiment, the fennel fed group had a significant decrease in body weight gain on the fourth day. Therefore, it may be effective in the reduction of food intake and weight gain.

Senna Alexanderina Pods and Leaf

One study found that senna with magnesium citrate may improve the quality of colonoscopy preparation as it can contribute to the cleansing outcome. This indicated a potential laxative effect, which may reduce bloating and reduce your weight temporarily on the scales. However, this is not an effective way to lose weight permanently and no clinical studies have come up with sufficient evidence to suggest that senna can help you to burn fat.

Rheum Rhabarbarum

One study looked at a dietary herbal formulation called Number Ten (NT), which contained rhubarb, ginger, astragalus, red safe and turmeric and its effectiveness in reducing body weight gain in rats. They believed this study demonstrated the efficacy of NT in reducing weight gain in rodents. They found that the NT treated group lost weight during the first 48 hours of treatment and continued to gain weight at a slower rate than the control group. It was effective in reducing body weight gain in rats that had been fed a high fat diet to induce obesity. Thus, the rats that received a high dose of NT and a low Dose of NT gained less weight than those in the control group.

Flat Tummy Tea Side Effects

Woman With Stomach Ache 538

The official website claims that there should not be any side effects associated with their product, due to it being supposedly 100% natural. It does mention that as it claims to detoxify your body, it may make you go to the bathroom. It also states that you might be a little dehydrated if you do not drink enough water.

It also mentions that the tea should not cause nausea, vomiting, severe abdominal pain or nay usual side effects, but in the rare case you do experience any, you should stop using it and consult your doctor.

Taraxacum Leaf and Root

Dandelion is thought to be safe for most adults to consume, however, not all side effects are yet known. It is suggested that if you are allergic to ragweed and other related plants, it is not recommended to have dandelion as you have the potential to also be allergic to it. As it may be a diuretic, it could cause dehydration and headaches.

Galium Aparine

When galium aparine is taken by mouth, it is possibly safe for most adults. However, there is not enough information known about the ingredient to know the extent of its safety, especially for those that are pregnant and breastfeeding. It is also not recommended for those that have diabetes.

Camellia Sinesis

It is thought that due to the caffeine, camellia sinesis may not be suitable for people who are sensitive to stimulants. Side effects may include headaches, irritability and tremors. For most people, it is thought to be safe to consume in moderation.


There is not enough known about the safety of scrophularia, especially for those that are pregnant, breastfeeding or diabetic. You should not use this if you have a heart condition called ventricular tachycardia, as it may not be safe to use. As it may be a diuretic, it could have the negative effect of decreasing how well the body gets rid of lithium.

Glycyrrhiza Glabra

As liquorice is used in foods, it may possibly be safe when consumed in larger amounts. However, liquorice may not be safe if you are using it for more than four weeks, as this might cause side effects such as high blood pressure, headaches, shortness of breath or missed menstrual periods.

Mentha x Piperita

Peppermint is thought to be possibly safe for most people, however, common side effects may include heartburn or signs of an allergic reaction, such as possible swelling or headaches. It is also thought to be safe for those that are pregnant or breastfeeding, but not in large amounts.

Carum Carvi

Carum Carvi is thought to be possibly safe for most people for a period of up to eight weeks. However, it may cause belching, heartburn and nausea. There is a concern that it might lower blood sugar and if you are diabetic you should watch your blood sugar level carefully. It could also increase iron levels, which may cause problems for those people who already have too much.

Melissa Offincinalis

Lemon balm may be safe but not enough is known about the ingredient when it is used long term. It would therefore not be recommended for those that are possibly pregnant or breastfeeding. Some side effects may include nausea, abdominal pain, dizziness and it could cause drowsiness. It may interact with sedative medications.

Foeniculum vulgare

The potential side effects of fennel are not commonly known. As it may pass into breast milk, you should not breastfeed while you are taking it. You could be allergic to fennel and those side effects may include swelling of your face and lips, difficulty breathing or hives.

Senna Alexandrina Pods and Leaf

One study that concentrated on the safety and efficiency of a laxative that contained senna found that there were no side effects reported. However, it may not be safe to take in high doses or for a period longer than two weeks. Another study found that it could cause abdominal cramps.

Rheum Rhabarbarum

Rhubarb stems are eaten in pie, other recipes and as a flavouring agent, thus, it may be possibly safe for most adults for up to three months. However, it might harm the kidneys and could cause kidney stones. Some side effects that could occur are stomach pain, muscle weakness, potassium loss and irregular heart rhythm. It is not recommended for those that suffer from Crohn’s disease, colitis and irritable bowel syndrome.

How to Use

Green Tea 538

The product comes with one pack of Activate loose leaf tea and one pack of Cleanse loose leaf tea, therefore you may need a diffuser. Instructions on how to use their produce are contained on the official website. It states that when you wake up, you should drink a cup of Activate tea at breakfast every morning. You should place one teaspoon of the blend into a tea strainer and infuse in a cup of hot water for 5-7 minutes. It states that you should drink the Cleanse tea every couple of nights before bed to supposedly help detoxify your system, reducing bloating and cleanse your digestive system. They say that as it contains a gentle herb that has a mild cleansing effect so you should start with a shorter infusion time to work out what is best for your body. Place a teaspoon of the tea in a tea strainer and infuse in a cup of hot water for 3-5 minutes.

The website states that their tea does not affect the contraceptive pill, but there may be a small chance it can due to the detoxifying nature of their Cleanse tea. It also says that there is no age limit but if you are under 18, you should check with a parent before ordering. It warns not to use if you are pregnant or breastfeeding.
