It’s marketed as a health drink and is gaining traction on social media sites, with influencers raving about its potential benefits for managing hunger pangs. But what exactly is this popular new carbonated In Tansan drink? Why is it called 'forbidden liquid jelly?' And, is drinking it a healthy way to support hunger management? This article delves into the hype surrounding In Tansan, its ingredients, potential health benefits, side effects, and whether you should consider incorporating it into your diet.

What is In Tansan?

In Tansan originates from the Japanese brand In and is a carbonated soda marketed as a ‘hunger management’ drink. It is available in dry grapefruit and lemon flavors, with the dry grapefruit boasting zero calories and the lemon flavor containing only 18 calories per can.

The drink, also known by the nickname ‘forbidden liquid jelly,’ claims to curb hunger pangs by expanding into a jelly-like substance once it hits the acid in your stomach. The jelly swells, supposedly making you feel full and less likely to reach for the snack jar. In Tansan has been hailed by fans as a natural Ozempic alternative, a drug that is used by some people off-label to manage hunger without the need for an expensive prescription for the popular drug.

Ingredients of In Tansan

The recipe for In Tansan remains somewhat of a mystery. It was assumed that the drink contained psyllium husk fiber as one of its ingredients, but the brand has kept it a secret.

Both the dry grapefruit and lemon flavors of In Tansan contain carbonated water as the primary ingredient, as well as a cocktail of various different minerals, flavorings, thickeners, and sweeteners.

The drinks also contain a compound called GABA (gamma-aminobutyric acid), an amino acid and neurotransmitter, which is produced naturally in the body and can be found in many other products marketed to health-conscious consumers. GABA is believed to support relaxation and potentially reduce stress, but there isn’t sufficient evidence to suggest that supplementation with the delicate compound has the same effects as when it is produced by the body.

The fact that the full ingredients list is somewhat elusive should definitely make you regard any health claims from this trending drink with a healthy dose of skepticism.

Potential health benefits of In Tansan

As with any new product that makes wild health claims and is popularized by social media influencers and bloggers, we have to cast a critical eye on any potential health benefits. There aren’t any scientifically robust studies on In Tansan, so we can’t say with any certainty whether it truly works to curb hunger and help with weight loss.

Hydration

The main ingredient listed for In Tansan is carbonated water. The natural fizz might make drinking water more enjoyable for some people who don't like the taste of still water, encouraging an increased fluid intake. Ensuring proper hydration is extremely important for overall health, as it aids in many essential bodily functions.

Digestive health

There isn’t any evidence to suggest that In Tansan actually helps with digestive health at all. The only evidence for carbonated drinks helping to alleviate symptoms of indigestion is purely anecdotal and should be taken with a pinch of salt.

Skin health

Hydration is important for skin health, helping it to maintain moisture and elasticity. However, when it comes to In Tansan, that’s as far as its skin benefits go. Drinking In Tansan isn’t going to replace a comprehensive skincare routine or offer the same skin health benefits as a balanced and healthy diet.

Appetite control

In Tansan has been marketed as a drink for hunger management. Its popularity is surging, and it frequently sells out within a few days. Because the recipe isn’t readily available for scientific examination, we don’t know the exact mechanism for its supposed hunger pang suppression.

Fans of the drink say that it helps them stay feeling full for up to two hours after drinking a single can. This reported characteristic is building the buzz around In Tansan as an alternative to proclaimed appetite suppressant drugs.

However, Ozempic, which is primarily a drug for diabetes management that is often used off-label for weight management, and other FDA-approved weight loss drugs such as Wegovy contain an active ingredient called semaglutide, known for appetite control. It’s unlikely that the ingredients of In Tansan are capable of delivering a noticeable reduction in weight or being specifically helpful along a weight loss journey.

Side effects and risks of In Tansan

While In Tansan is promoted as a drink that can curb your hunger pangs, it’s important to consider the safety and side effects of consuming it. Since the full ingredients list is not clear, it's impossible to know the full spectrum of side effects that might occur from its consumption.

Stomach issues. Drinking lots of carbonated beverages might cause bloating or discomfort, especially when consumed in high quantities.
Highly processed food. In Tansan drink contains a mix of many different chemicals, which may make it an ultra-processed food (UPFs). In recent years, there has been a shift in focus toward the potential negative health outcomes from consumption of UPFs.

Should you try drinking In Tansan?

The decision whether or not to try drinking Tansan is completely based on personal preferences. There’s no scientific backing to suggest that it really does help with hunger management or weight loss. All the evidence is purely anecdotal and comes from social media fans and influencers, who aren’t a trusted source.

It’s important to look at these kinds of products, which are surrounded by hype and very little actual evidence, with healthy skepticism. Different foods and drinks that are marketed as miracle weight loss aids should never replace the need for a balanced diet and exercise regimen. Maintaining healthy weight and fitness levels isn’t something that happens overnight — it’s an ongoing practice that asks us to build healthy habits around how we nourish ourselves.

If you are considering adding In Tansan to your dietary regimen, it’s important to consider your individual health needs and always consult with a qualified healthcare professional if you have any concerns.
