A cortisol cocktail is a drink of orange juice, coconut water, a pinch of salt and cream of tartar, popular on TikTok for “balancing cortisol”. There’s no evidence it lowers cortisol, fixes “adrenal fatigue” or helps weight loss. It’s a reasonably hydrating mocktail, but sleep, movement and less caffeine do far more for stress.
Below: the recipe, what each ingredient really does, whether it works, who should avoid it, and a lower-sugar UK version.
What is a cortisol cocktail?
It’s a rebrand of the older “adrenal cocktail” from alternative health circles. The idea is that stress drains your adrenal glands, and that vitamin C, potassium and sodium “feed” them so cortisol settles down. Influencers suggest drinking it mid-morning or mid-afternoon, often promising more energy, less belly fat and fewer cravings.
Cortisol is a real and essential hormone. It naturally peaks soon after you wake and falls through the day, and it rises in response to stress, poor sleep and illness. See how to lower cortisol naturally.
Cortisol cocktail recipe (UK measures)
The classic version, for one glass:
- 120ml orange juice
- 120ml coconut water
- a pinch of sea salt
- ¼ teaspoon cream of tartar
- ice, and sparkling water to top up if you like
Stir until the cream of tartar dissolves. Some recipes add a scoop of magnesium powder, collagen or a squeeze of lime.
A lower-sugar version: use 75ml orange juice, 150ml coconut water, a pinch of salt and plenty of ice, then top up with sparkling water. The NHS advises limiting fruit juice to 150ml a day in total, so the classic recipe uses most of that allowance.
What each ingredient actually does
| Ingredient | What it adds | Effect on cortisol |
|---|---|---|
| Orange juice | Vitamin C and natural sugars. Vitamin C contributes to the reduction of tiredness and fatigue. | No proven effect |
| Coconut water | Potassium and fluid | No proven effect |
| Sea salt | Sodium, useful if you’ve sweated a lot | No proven effect; most UK adults already eat too much salt |
| Cream of tartar | Potassium (it’s potassium bitartrate, a baking ingredient) | No proven effect |
| Magnesium (optional) | Magnesium contributes to the reduction of tiredness and fatigue and to normal psychological function | Small, low-quality studies on stress; no proof it lowers cortisol |
Does the cortisol cocktail work?
Not in the way it’s sold. There are no studies of the cortisol cocktail itself, and the theory behind it doesn’t hold up:
- “Adrenal fatigue” isn’t a recognised condition. A systematic review of 58 studies concluded there was no evidence that it exists. Healthy adrenal glands don’t “run out” from stress.
- Real adrenal problems are medical conditions, such as Addison’s disease, which need diagnosis and prescribed treatment, not a drink.
- Nutrients only help if you’re short of them. If you eat a reasonable diet, extra potassium and vitamin C won’t change your hormones.
Why do some people feel better? A cold, slightly salty, sweet drink mid-afternoon can lift energy if you were thirsty or hadn’t eaten, and taking a few minutes for yourself is calming in its own right. That’s a fine reason to enjoy one, as long as you’re not relying on it.
Does the cortisol cocktail help weight loss?
No. There’s no evidence it reduces belly fat or “cortisol belly”. The classic recipe has around a glass of juice’s worth of sugar, so having it daily adds calories. Long-term stress and poor sleep can affect appetite and weight, which is why sleep and stress habits matter more than any drink. See cortisol face and does magnesium help with weight loss?
Side effects and who should avoid it
For most healthy adults one glass is harmless. Skip it, or check with your GP or pharmacist first, if you:
- have kidney disease, or take medicines that raise potassium, such as some blood pressure tablets (ACE inhibitors, ARBs) or potassium-sparing diuretics. Cream of tartar and coconut water are both high in potassium, and too much can affect your heart rhythm.
- have high blood pressure or are told to cut salt.
- have diabetes or are watching sugar intake.
- have a real adrenal condition, where you need medical advice rather than a home remedy.
Don’t take more cream of tartar than the recipe suggests.
What lowers cortisol instead
| Habit | Why it helps |
|---|---|
| Regular sleep | Short or broken sleep keeps stress hormones higher the next day |
| Daylight in the morning | Helps set your body clock and the normal daily cortisol rhythm |
| Movement most days | Walking and moderate exercise help you handle stress |
| Less caffeine after midday | Caffeine raises alertness and can worsen sleep and jitters. See does caffeine cause anxiety? |
| Less alcohol | Alcohol disrupts sleep in the second half of the night |
| Breathing and wind-down time | Slow breathing and a calm evening routine help you switch off |
If you’d like a drink ritual that fits this, try an evening magnesium drink or a warm reishi cacao instead of a sugary afternoon cocktail. Magnesium contributes to normal psychological function. See magnesium for anxiety and the sleepy girl mocktail, the bedtime cousin of this trend.
FAQs
What is in a cortisol cocktail?
Orange juice, coconut water, a pinch of salt and cream of tartar. Some versions add magnesium powder or collagen.
Does the cortisol cocktail actually work?
There’s no evidence it lowers cortisol or fixes “adrenal fatigue”, which isn’t a recognised condition. It’s a hydrating drink, nothing more.
When should you drink a cortisol cocktail?
Influencers suggest mid-morning or mid-afternoon. There’s no best time, because there’s no proven effect on cortisol.
Can I drink a cortisol cocktail every day?
Most healthy adults can, but it uses most of the NHS 150ml daily juice limit and adds salt. Avoid it if you have kidney disease or take medicines that raise potassium.
Does the cortisol cocktail help you lose weight?
No. There’s no evidence it reduces belly fat, and the juice adds sugar and calories.
