Can the cortisol cocktail help you lose weight? Here’s what the experts say

The cortisol cocktail is the latest in a line of viral “functional” drinks that claim to help people lose weight and solve other health issues with a few sips. “Natural Mounjaro,” the pink Himalayan salt drink, and Oatzempic are a few of the others that fall in this category. Like these beverages, the cortisol cocktail is a drink made with simple everyday ingredients that has developed a devoted online following. But can it really do what it claims to do? 

Fans say the “cortisol cocktail” can reduce stress, boost energy, and even lead to weight loss. The alcohol-free ingredients are said to balance cortisol, a hormone that is produced in excess when you experience ongoing stress. But does it really do what it claims to do?

To answer that, we’ll discuss what the drink is, how it’s made, and whether its components—together or separate—can improve your stress levels and lead to weight loss. We’ll look at the science behind the ingredients in the trending drink and what they can—and can’t—do for your health. We’ll also reach out to our in-house experts to get their take on the ingredients and find out if it’s safe.

What is the “cortisol cocktail” and why is it popular?

The “cortisol cocktail” is a drink that’s typically a mix of orange juice, coconut water, and sea salt. Occasionally, some other ingredients are added. It’s become popular on social media as a way to lose weight and help with stress. 

Fans of the drink claim that drinking it daily can help regulate stress and lead to benefits like better mood, fewer afternoon energy crashes, and easier weight loss.

To understand whether this drink can live up to these claims, it helps to first look at how cortisol works.

Often called the “stress hormone,” cortisol is released by the adrenal glands during times of stress to give the body a quick burst of energy. But cortisol does much more than respond to stress—it plays a central role in metabolism, blood pressure, immune function, inflammation, mood, and the sleep-wake cycle. 

These systems are all connected to how your body manages weight and handles stress, which is why cortisol is often at the center of wellness trends—even if the science behind them is still evolving.

When stress becomes chronic, cortisol levels can stay elevated for long periods. Research has linked elevated levels of this hormone to poor sleep, fatigue, increased pain sensitivity, and weight gain. Chronically high cortisol may:

• Increase appetite, especially for high-fat, high-sugar foods
• Promote fat storage, particularly around the abdomen
• Disrupt sleep and slow recovery
• Impair insulin sensitivity and energy regulation

“Recently, I’ve noticed more and more patients expressing concern about their cortisol levels and stress,” says Dr. Karen Mann, MD, Medical Director at Noom. “It’s important to remember that the endocrine system is a complicated and interconnected structure that works in harmony. Focusing on one hormone or gland in isolation often overlooks the bigger picture of your body’s intricate balance.”

What’s in a “cortisol cocktail” 

The standard cortisol cocktail recipe doesn’t contain any hormone-altering ingredients or medications. Here’s a closer look at the typical “cortisol cocktail” recipe:

• Coconut water (about 1 cup): Coconut water is naturally rich in electrolytes like potassium and magnesium, which may help keep you hydrated and support muscle function.
• Orange juice (¼ to ½ cup): This adds flavor and a boost of vitamin C, which supports collagen production and immune health.
• Sea salt (¼ teaspoon): Salt adds sodium and trace minerals to support hydration and fluid balance. Some prefer pink Himalayan salt for its extra trace minerals, though there’s no nutritional difference (nd there’s no proof that Himalayan salt has any special benefits over regular salt).

When mixed together, the result is a sweet-salty citrus drink that many say tastes like an orange creamsicle.

Popular variations of the “cortisol cocktail” and other ingredients

Many people tweak the recipe by adding extra ingredients to boost electrolytes, improve taste, support sleep, or enhance perceived stress-relief benefits. These additions reflect a growing interest in functional beverages for wellness and energy.

Some common modifications and why they’re used include:

• Cream of tartar: A teaspoon of this powder adds about 495 mg of potassium—roughly 10% of the RDA* for adults. This essential electrolyte helps ensure muscles, including the heart, contract properly. It also helps your body with fluid balance and hydration. 
• Lemon juice: Fresh lemon or lime juice is added for flavor and for extra vitamin C, which may support immune function and digestion.
• Collagen: Collagen peptides are often included to support skin, joint, and gut health. 
• Honey: Honey helps balance the acidity and adds trace antioxidants. 
• Magnesium powder: Some people add a sprinkle of magnesium to help with sleep. Certain forms of magnesium are associated with improved sleep and relaxation. Magnesium also plays a key role in supporting nerve function and regulating your response to stress.

*Recommended dietary allowance (RDA) is defined as the average daily amount of nutrients required to meet the needs of nearly all healthy people.

Does the cortisol cocktail lower stress or help with weight loss? 

While all of these ingredients have their individual health merits, can they really help people manage stress or lose weight? Let’s see what the science says.

Claim 1: The cortisol cocktail can lower stress levels

Verdict: False.

Chronic stress can be linked to elevated cortisol levels. And, while staying hydrated and eating nutritious foods can help improve stress levels, a drink won’t do it. 

“You can’t lower stress with a drink,” says Dr. Jeffery Egler, MD, Chief Medical Officer at Noom. “But you can reduce the effect of that stress in the body and alter the response. Maybe think of it as diminishing the ‘noise’ of stress—decreasing the stress footprint and dampening the stress response.”

Meaningful stress reduction usually requires consistent lifestyle strategies like regular exercise, a nutrient-dense diet, quality sleep, and mindfulness techniques.

Ingredients like orange juice, coconut water, lemon, honey, and salt don’t directly reduce cortisol, but they can help you feel better temporarily by replenishing fluids and electrolytes. 

Claim 2: The cortisol cocktail can help you lose weight

Verdict: False.

One of the more popular claims on social media is that by reducing cortisol levels, the drink can help people lose weight. But since one drink can’t lower cortisol, it’s also unlikely to influence weight loss, unless it’s part of a reduced-calorie diet.

It’s true that having high cortisol levels over time can lead to weight gain—especially around your midsection. This pattern is often seen in people with Cushing’s syndrome, a rare condition where the body makes too much cortisol. People with Cushing’s often develop belly fat, muscle weakness, easy bruising, and other symptoms.

But for people without this diagnosis, weight gain is far more likely to be the result of lifestyle choices or metabolic factors, not a hormonal disorder.

“When a patient comes to me concerned about their symptoms and I notice new weight gain around the belly, bruising, or muscle weakness, this needs to be taken seriously,” says Dr. Mann. “If you’re worried about potentially having Cushing’s syndrome, please get a proper medical evaluation. You can’t self-diagnose a cortisol disorder—or fix it with a popular drink.”

This cocktail won’t burn fat, shrink your waistline, or correct a hormonal imbalance. If you’re struggling with weight, first take a look at your habits. If you aren’t seeing progress, talk to your doctor about other options.

Claim 3: Adding magnesium to the “cortisol cocktail” can improve sleep

Verdict: Partially true—but with limitations.

Some versions of the cortisol cocktail include magnesium powder, based on the idea that it can help you sleep better—and there’s some science to back that up. A review in Sleep Health found that magnesium supplements can modestly improve sleep quality, especially in people who are low in magnesium or already struggling with sleep.

That said, there isn’t a single form, brand, or dose that works for everyone. One recent study pointed to magnesium L-threonate as a potentially helpful type.

So why does this matter for weight? Better sleep may help regulate appetite. In one study, adults who got just one more hour of sleep per night naturally ate about 270 fewer calories a day—without trying to eat less.

If you’re having trouble sleeping, it’s worth focusing on your bedtime habits first

If you’re working on better sleep, here are a few evidence-based lifestyle changes that can help:

• Stick to a regular bedtime and wake time, even on weekends.
• Limit caffeine in the afternoon and alcohol before bed.
• Avoid screens and bright lights an hour before sleep.
• Try gentle movement or mindfulness exercises in the evening.
• Ensure your sleep environment is cool, dark, and quiet.

If sleep problems stick around or get worse, see a doctor.

Claim 4: The cortisol cocktail can give you energy.

Verdict: Maybe.

The cortisol cocktail isn’t an energy drink, but if you’re mildly dehydrated, it might give you a quick boost. But for most people, especially those who aren’t highly active, plain water is usually enough.

“I recommend drinking water for hydration because it doesn’t contain sugar,” says Dr. Mann. “Getting quality sleep, moving your body, eating nutritious foods, and having a strong sense of community are other ways to feel more energetic without relying on a single drink.”

Important: If you’re experiencing severe fatigue, dizziness, or signs of dehydration, seek medical attention right away.

Is the “cortisol cocktail” safe?

The combination of ingredients in the standard cortisol cocktail is safe for most healthy people when you drink it in moderation.

“A cortisol cocktail is essentially a DIY sports drink made with household ingredients,” says Dr. Mann. “In moderation, it is unlikely to cause harm, but the benefits may be exaggerated.”

That said, there are a few things to keep in mind:

• Consider eating whole fruits instead of drinking juices: Eating an orange has more fiber than drinking juice, which will keep you fuller for longer and lead to more stable blood sugar.
• Watch out for the extra sodium: If you’re adding sea salt, it’s worth measuring it out. Too much sodium can sneak up quickly—especially if you’re already getting it from packaged foods or restaurant meals. The American Heart Association (AHA) suggests aiming for no more than 2,300 mg per day, with 1,500 mg being ideal for most adults.
• Watch your other sources of potassium: A teaspoon of cream of tartar adds about 495 mg of potassium, which is about 10% of the RDA. That’s not a problem for most people, but if you’re also eating a lot of potassium-rich foods (like bananas or avocados) or taking supplements, it’s something to be aware of. If you have kidney issues or take medications that affect potassium, check with your doctor.
• Don’t take too much magnesium: Adding a bit of magnesium powder might help you sleep, but more isn’t always better. Some powders pack 150–250 mg per teaspoon, and doses over 350 mg from supplements can lead to digestive trouble (yes, we’re talking diarrhea). Start small and see how your body responds.
• Citrus juice can be an acid reflux trigger: Citrus ingredients like orange juice and lemon can trigger acid reflux, especially if you have GERD. If you notice heartburn after drinking the cocktail, citrus might be the cause.

The cortisol cocktail is unlikely to cause harm in moderation for most healthy people. But if you’re drinking it daily, watch your intake of salt, potassium, magnesium, and acidic ingredients—especially if you have existing health conditions or take medications. And as with any wellness trend, it’s not a substitute for medical care or a balanced diet.

How to include the “cortisol cocktail” in your diet safely

Before adding the “cortisol cocktail” or any new supplement to your routine, it’s a good idea to talk to your healthcare provider, especially if you have any underlying health conditions or take medications.

• The FDA doesn’t regulate magnesium powders and other supplements, so if you’re considering adding one to your drink, choose products that have third-party testing for purity and dosage accuracy.
• Sodium is another important consideration. High sodium intake can be dangerous for people with high blood pressure, and many people may not realize they have it. Even if you’re in good health, it’s best to stick with a small pinch of salt when preparing this drink and monitor your overall sodium intake throughout the day.
  

The bottom line: The cortisol cocktail isn’t a solution for weight loss

The “cortisol cocktail” isn’t a stress-reducing, energy-boosting, weight loss drink. While it may keep you hydrated and provide a modest dose of electrolytes or nutrients, there’s no solid scientific evidence that it lowers cortisol levels or directly promotes weight loss.

“Weight loss is a complex biological process that can’t be achieved by adding or eliminating one beverage,” says Dr. Mann. “Still, I’d prefer my patients to choose whole fruit over juice given its effect on blood sugar.”

If you’re using the drink in place of higher-calorie or high-caffeine drinks, it could help you lose weight. But it’s not comparable to proven weight loss strategies like a balanced, calorie-controlled diet, regular physical activity, behavioral changes, or medications like GLP-1 receptor agonists (if needed).

It’s also important to drink it safely. Ingredients like salt, magnesium, and cream of tartar can add up if taken in excess or without guidance. People with high blood pressure, kidney issues, or who are on medications should talk to a healthcare provider before making it a daily habit. And since supplements like magnesium powder aren’t regulated by the FDA, look for third-party testing if you plan to use one.

Losing weight—and keeping it off—requires more than a daily drink. A comprehensive approach that includes nutrition, movement, and stress management is key. For a science-backed strategy, explore what Noom offers and get on the track to sustainable weight loss.
