Does Flat Belly Shake really work? Can it really give you a flatter belly? Please keep reading to find out everything you need to know about Flat Belly Shake and how it works.


What is Flat Belly Shake?

Flat Belly Shake, also known as the Lanta Flat Belly Shake, is a weight loss supplement that uses plant extracts, herbal extracts, vitamins, and nutrients to help you lose weight.

By taking one scoop of Flat Belly Shake daily, you can boost metabolism, speed up fat burning, reduce cravings, and lose weight.

Millions of people struggle with stubborn belly fat. Even if you’re dieting and exercising, it can be difficult to remove the fat around your tummy, thighs, butt, and hips. According to the makers of Flat Belly Shake, this is called weight loss resistance: your belly fat refuses to go away, no matter what you do.

By taking Flat Belly Shake daily, you can purportedly lose weight by targeting hormones using five powerful plant extracts, among other ingredients.

The manufacturer of Flat Belly Shake recommends mixing one scoop of the formula with 6 ounces of water and then taking it each morning. The company recommends taking Flat Belly Shake about an hour after eating breakfast.

How Does Flat Belly Shake Work?

Flat Belly Shake targets a hormone that inhibits your weight loss goals.

There’s a hidden cause of frustrating, unwanted fat within your body. Normally, when you eat foods, your body releases GLP-1. It’s a metabolism hormone that slows down the absorption of glucose into your blood. It tells your body to convert food into energy instead of storing it as fat. It also helps you feel more satisfied after eating.

Unfortunately, GLP-1 doesn’t always work right. Sometimes, you can’t melt fat even if you’re doing everything right – because GLP-1 is inhibiting your weight loss results.

When your GLP-1 is imbalanced, you absorb food too quickly after eating, causing blood sugar to skyrocket. Here’s how the makers of Flat Belly Shake explain what happens next:

“Glucose is streaming into your blood too fast for your insulin to convert it to energy. So your liver converts this surplus glucose to fat and stores it on your belly, buns, hips, arms, and even your face.”

Fortunately, the makers of Flat Belly Shake found a way to support your GLP-1 hormone using plant extracts, making it easier to lose weight by inhibiting fat storage.

Flat Belly Shake can also help the hormone fight oxygen radicals in the gut linked to inflammation by supporting this hormone. Oxygen radicals are disruptive molecules created by pollution, radiation, and toxins in water and food.

Flat Belly Shake Ingredients

Flat Belly Shake contains five ingredients that can purportedly support your GLP-1 hormone, boost your metabolism, and support weight loss in other ways.

The five core ingredients include:

Metabolic Burner 1: Mangosteen: Flat Belly Shake contains mangosteen, a fruit extract that contains powerful antioxidants to support metabolism. Mangosteen is packed with a specific type of antioxidant called xanthones. According to FlatBellyShake.com, xanthones target the same oxidative stress that causes dangerous fat storage, which means they shut down the root cause of belly fat and free up your metabolism to melt fat.

Metabolic Burner 2: Panax Ginseng: Ginseng has been used in traditional medicine for centuries. It’s prevalent in multiple types of traditional Asian medicine, including traditional Korean and traditional Chinese medicine. According to FlatBellyShake.com, the ginseng in Flat Belly Shake contains powerful ginsenosides components that help block fat cell formation. Overall, the company claims ginseng can prevent you from getting fat while also increasing energy and focus.

Metabolic Burner 3: Cinnamon Bark: Flat Belly Shake contains cinnamon bark, a popular spice that has also been used in traditional medicine for centuries. According to FlatBellyShake.com, cinnamon extract can trigger thermogenesis, a metabolic process where your body burns calories to produce heat. Some studies also show that cinnamon can help support blood sugar, so many people with diabetes take cinnamon extract daily.

Metabolic Burner 4: Ashwagandha: Ashwagandha is a popular adaptogenic ingredient. It’s been used for similar purposes for over 3,000 years. Like other adaptogens, ashwagandha has been shown to support your body’s response to stress and anxiety. According to the manufacturer of Flat Belly Shake, ashwagandha can also help you convert more of your food to pure energy instead of fat, making it easy to lose weight while blocking fat storage.

Metabolic Burner 5: EGCG: Epigallocatechin gallate (EGCG) is a natural extract found in green tea. Studies show EGCG can increase the rate of fat oxidation or fat burning, making it easier to lose weight.

Many people take green tea extract daily for weight loss, inflammation, and other effects.

According to FlatBellyShake.com, all of the ingredients above are proven metabolism boosters. However, according to the ingredients label, Flat Belly Shake contains other ingredients, including melatonin, chamomile, and tryptophan.

Flat Belly Shake Ingredients Label

According to the Flat Belly Shake ingredients label, the supplement contains ingredients linked to relaxation, anxiety, and stress relief. The supplement contains many ingredients found in sleep aid supplements, including chamomile, tryptophan, and melatonin, for example, among other ingredients found in sleep aids.


Each scoop of Flat Belly Shake (2.75g of formula per scoop) contains the following ingredients and dosages:

  • 1,000IU of vitamin A (20% DV)
  • 50mg of vitamin C (83% DV)
  • 1,000 IU of vitamin D (250% DV)
  • 60mcg of vitamin K (75% DV)
  • 5mg of zinc (33% DV)
  • 10mcg of chromium (8% DV)
  • 500mg of chamomile flower powder
  • 1,000mg of hibiscus powder
  • 30mg of passionflower extract
  • 150mg of tryptophan
  • 500mg of gamma-aminobutyric acid (GABA)
  • 100mg of stevia (with 90% rebaudioside A)
  • 30mg of hops flower powder
  • 3mg of melatonin
  • 367mg of white willow bark extract

According to the ingredients label posted on FlatBellyShake.com, Flat Belly Shake does not contain mangosteen, cinnamon bark extract, or any other proven metabolism boosters listed on the website. Instead, the supplement contains popular sleep aid ingredients.

Can a Better Sleep Lead to Greater Weight Loss?

Flat Belly Shake claims to help you lose weight and optimize metabolism using natural ingredients. Instead of using metabolism boosters, Flat Belly Shake seems to use ingredients like melatonin, tryptophan, and hibiscus powder.

These ingredients have been shown to help you fall asleep and get a more restful sleep. However, is it possible a restful sleep can help you lose weight?

According to this 2011 study, poor quality sleep can undermine efforts to lose weight. Even if you’re doing everything right for dieting and exercising, your poor sleep could make it impossible to lose weight.

By optimizing sleep and helping you relax, Flat Belly Shake could make it easier for your body to lose weight.

Many of the ingredients in Flat Belly Shake also work as adaptogens, which means they help your body respond to stress. Stress can raise cortisol in your body, and cortisol tells your body to hold onto stubborn fat. By lowering cortisol, you could make it easier to lose weight.

In other words, it’s possible Flat Belly Shake can help you lose weight by preparing your body to release fat by relaxing and reducing stress levels. However, because the supplement appears to contain doses of multiple sleep-inducing ingredients, Flat Belly Shake may not boost energy. Instead, it’s best taken before bed to help you get a more restful sleep.

How to Take Flat Belly Shake

Flat Belly Shake appears to contain ingredients that can help you fall asleep and enjoy a more restful sleep. However, the company recommends taking it at breakfast – which seems counterintuitive.

Here’s how the company recommends taking Flat Belly Shake:

  • “Mix a single scoop daily of Flat Belly Shake with 6 ounces of water each morning. We recommend taking Flat Belly Shake around 1 hour after eating breakfast.”

Taking melatonin at breakfast can make you feel sleepy. Other ingredients, including tryptophan and chamomile, could also make you feel sleepy. By taking these ingredients in the morning, you could feel sleepy throughout the day – which seems to counteract the other effects of Flat Belly Shake.

Nevertheless, the makers of Flat Belly Shake insist their formula can boost energy and metabolism while making it easier to lose weight.

Scientific Evidence for Flat Belly Shake

Flat Belly Shake claims to boost energy and metabolism. However, the supplement also seems to contain ingredients that do the opposite: most of the ingredients in Flat Belly Shake are the same ingredients found in sleep aid supplements or stress management formulas.

FlatBellyShake.com, Flat Belly Shake contains ingredients like melatonin, tryptophan, and hibiscus powder, all of which are popular ways to manage stress and anxiety. Based on the ingredients listed online, Flat Belly Shake should help the body relax and manage stress, although it seems unlikely to boost your energy or lead to significant weight loss.

Flat Belly Shake contains 3mg of melatonin. That may not sound like a large dose. However, studies show that doses of 0.5mg to 10mg of melatonin can cause significant sleepiness. Many people take melatonin nightly to help them fall asleep. According to this 2014 study, melatonin has been shown to induce sleep in some studies, although it hasn’t worked in all participants in all studies rapidly. A 3mg dose of melatonin (as found in Flat Belly Shake) is considered moderate, and it should have noticeable effects in inducing sleepiness.

Flat Belly Shake also contains a significant amount of chamomile powder (500mg per serving). As this 2010 study explained, chamomile is an herbal medicine of the past with a bright future: studies show that chamomile contains many terpenoids and flavonoids that contribute to its medicinal properties. These ingredients can make the dried flowers of chamomile, the essential oils of chamomile, and chamomile teas particularly powerful for supporting overall health and wellness.

Flat Belly Shake has a large dose of hibiscus (1,000mg per serving). In the supplement space, hibiscus is best known for its effects on blood pressure. Many people take hibiscus daily for hypertension. Studies show that taking hibiscus twice a day can effectively manage blood pressure in patients with stage one hypertension when used in conjunction with lifestyle and dietary changes.

Many supplements contain gamma-aminobutyric acid (GABA). According to this 2020 study, oral GABA administration can affect stress and sleep in humans. Studies show that an oral dose of GABA could make it easier to fall asleep, reduce stress, and get better-quality sleep, among other benefits.

Overall, Flat Belly Shake contains an unusual combination of ingredients. According to the official website, Flat Belly Shake contains proven metabolism boosters like mangosteen and ashwagandha. However, the official ingredients label reveals proven relaxing herbs and plant extracts like melatonin, chamomile, and hibiscus, all of which are found in sleep aids. Based on the ingredients and dosages listed, it’s possible Flat Belly Shake can help you fall asleep and get a night of better quality sleep – but it’s unlikely to boost energy or lead to significant weight loss.
