Debunking the Pink Salt Trick

Written by Tom Price, Accredited Practising Dietitian

The new kid on the block and viral TikTok trend, The Pink Salt Trick, has captured global attention, with a multitude of claims that it can hack the body and restore health. From boosting hydration to enhancing metabolic health, improving sleep and reducing bloating, this simple 'hack' seems too good to be true. And you know what they say about things that sound too good to be true.

So, what exactly is The Pink Salt Trick?

In case you haven't come across it, the 'trick' involves drinking a cup of room-temperature water mixed with a pinch of pink Himalayan salt, juice of half a lemon, and optional honey or apple cider vinegar. Sounds delicious, right?

It is here that a disclaimer is warranted. The Pink Salt trend is an extreme example of how weight loss or intense dietary interventions most certainly do not always mean health gain and, in many instances, may result in the opposite. Exposure to quick fixes and rapid 'transformations' online promotes unrealistic expectations and may develop into an eating disorder. For those already experiencing the signs of an eating disorder, using the drink as a 'reset' or compensatory tactic following a bingeing episode is also a real risk. These risks are not unique to The Pink Salt Trick, but serve as one example of how extreme dieting promotes disordered eating and eating disorders.

In this article, we will dissect these claims and see how they stack up against the evidence. Noteworthy is the fact that The Pink Salt Trick has zero scientific research investigating any of the heavy-hitting claims, likely due to (spoiler alert) having no plausible reason to do so. 

Claim - It’s A Tricky Way To Optimise Hydration

The combination of electrolytes like sodium (AKA salt) with water is a known strategy to retain fluid and hydrate. However, we need to bring two things into context here. The first is that the average Australian adult already consumes upward of 9g of dietary salt per day, 4g above the WHO-recommended daily limit (Land et al., 2018). This is a major public health concern given the increased risk of heart and kidney problems, primarily due to elevated blood pressure and often subsequently high blood sugars. The second is that water itself is already hydrating, with little need to add electrolytes such as sodium to fluid unless exercising in very hot conditions and/or for extended periods of time, such as ultraendurance events (McCubin, 2025). There are also many more pleasant options, such as milk, soup or consuming food alongside water if one is set on consuming electrolytes with their fluid.

Overall, not only is excessive sodium intake a concern for many Australians, but the need to add salt to fluid is unnecessary for hydration most of the time, meaning The Pink Salt Trick is redundant in the majority of cases.

Claim - The Pink Salt Trick Has Special Weight Loss Benefits

This is perhaps the most common claim. However, for those living with higher body weights and interested in bodyweight-focused approaches, this strategy lacks scientific evidence, poses a substantial disordered eating risk, and does not meet the hype when it comes to appetite suppression or metabolism-boosting claims. Bodyweight-focused approaches involve creating a calorie deficit. That is, consuming 10-30% fewer calories than what is required to maintain current body weight. Claims are seen on both sides of this equation, where some indicate The Pink Salt Trick reduces appetite and therefore the amount of food consumed, and that it somehow “boosts” metabolism.

Claim - The Pink Salt Trick Will Boost My Metabolism

Metabolism refers to all the processes your body uses to turn food into usable energy – everything from keeping your heart beating and lungs working, to digesting food, repairing cells, thinking, moving, and regulating temperature. These processes require fuel, which is why our bodies need regular, adequate intake of food.

The Pink Salt Trick doesn’t meaningfully change any of these processes. It doesn’t increase movement, doesn’t require digestion in any meaningful way, and doesn’t stimulate any organ systems to work harder. In other words, it doesn’t create extra energy demand.

We don’t have research directly testing this, but physiologically it’s very unlikely to “boost” metabolism. In fact, a food that contains actual nutrients – like a chocolate thickshake – requires your digestive system to break down carbohydrate, protein, and fat, which uses more energy than digesting salty lemon water. That doesn’t make the thickshake a “metabolism hack”; it simply reflects that real food requires real digestion, whereas this drink does not.

Claim - Using The Drink Will Help Keep Hunger At Bay

Our appetite is tightly regulated by our brain, stomach and gut through a variety of mechanical (e.g. chewing, stomach stretching) and hormonal functions (e.g. brain hormones) which have evolved to ensure we never suffer starvation. When taking weight-focused approaches, managing hunger is useful to ensure a calorie deficit is maintained. However, there are two things to consider.

First, avoiding hunger is impossible and exists for a reason - to keep us adequately fueled. Second, The Pink Salt Trick has no known impact on any regulators of hunger and appetite, again, due to a lack of scientific evidence. Anyone claiming to have an appetite-suppressing effect from this strategy is either experiencing a placebo effect (which will soon be overridden by physiology) or is not accounting for another variable, such as simply feeling full from food or the use of GLP1 medications. Neither of these is a failure of the person but a misunderstanding of the drivers of appetite.

In summary of the last three claims, we are confident to say that The Pink Salt Trick does not help individuals with weight-focused endeavours. While there is no impact on metabolism, the more important point is that it is unlikely to promote a feeling of fullness and satisfaction in the absence of food. Not only does this lead to cravings later on, but the risk of disordered eating is real.

Claim - I’ll Sleep Better If I Drink It Before Bed

The bidirectional relationship between food and sleep has become widely recognised as a key pillar of health. Indeed, several supplements and nutrients have some evidence for improving sleep onset, duration, and quality, such as Magnesium, L-Theanine, Kiwi Fruit and Tart Cherry Concentrate (Conti, 2025), just to name a few. Likewise, the timing of food and its effect on sleep and health has earned its own unique term, Chrononutrition. It is thought that the timing of food influences various aspects of health, including sleep, through mechanisms relating to our circadian rhythm. Without getting too far into the weeds, circadian rhythms regulate our sleep-wake cycle, digestion, body temperature and hormone release over a 24hr period to optimise how our body functions at various times during the day. The primary influence on circadian rhythms is exposure to light and darkness, but meal timing also influences these functions in that, for example, eating in the middle of the night might confuse the 24hr clocks such that the body may think it is day time.

So, there is both timing of food and the nutrients within that food that we know can influence sleep. Sipping salty, sour water has no research that we know of looking into its influence on sleep both from a timing (chrononutrition) and provision of nutrients perspective. In fact, drinking excessive fluid before bed may lead to disrupted sleep if it causes one to wake during the night to visit the restroom. 

Claim - Drinking It Will Help Me Sleep Like A Baby

Bloating is another hot topic supposedly addressed by The Pink Salt Trick, and again, no scientific research backs the claim. Staying hydrated does support gut function, but whether adding salt and lemon helps or hinders is a different question entirely.Research on lemon and bloating is sparse, and anecdotal evidence is mixed. The closest relevant study is a randomised controlled trial of healthy American adults who consumed either >400mL of pulpy orange juice (providing 10g fibre, which is a fair bit) or a matched control drink (Dennis-Wall et al., 2019). Pulpy OJ improved stool frequency and consistency, but it also increased gas and bloating - likely due to the higher fibre load, though other factors may have contributed (Dennis-Wall et al., 2019).The Pink Salt Trick uses lemon rather than orange juice, doesn't specify pulp inclusion, uses roughly half the fluid volume, and adds salt making any direct comparison difficult. In practice, we're left relying on anecdotes and loosely related studies like this one. What we do know is that excessive salt intake, which is common across most Aussie adults (Land et al., 2018), can promote abdominal bloating through fluid retention, altered gut motility (Peng et al., 2019), and changes to gut microbiota (Wang et al., 2024). A few fragments of the bloating puzzle exist, but significant gaps remain.

Whether The Pink Salt Trick eases bloating likely varies by individual. Proven alternatives exist depending on the underlying cause, and discussing these with a doctor or dietitian is the best starting point.

Conclusion

The simple and seemingly incredible benefits of starting (or ending) the day with a face-twisting beverage like The Pink Salt Trick are sold as a hack. Like many things that seem too good to be true, this strategy probably is too. Whether it be for boosting hydration, enhancing metabolic health, optimising sleep, or beating the bloat, there doesn’t seem to be any real benefit or direct evidence justifying putting oneself through the misery of drinking this concoction. In some cases, there are real risks associated with disordered eating, high blood pressure, metabolic health, sleep, and potentially bloating. In other words, it potentially does the complete opposite to what the claims say.

If you’re looking to support your energy, digestion or sleep, simple habits like regular meals, enjoyable fluids, and predictable routines are far more effective - and far kinder to your body - than any viral trend. And if you’re finding it hard to sort through conflicting advice or you’d like support that honours your sensory needs, routines, and lived experience, a dietitian (Guardian Dietitian) will help you find approaches that genuinely fit your life.
