I tried lemon water with cayenne and Celtic salt for a week. Here’s what happened…

I’ve reached an age where I’m suspicious of anything described as a morning elixir. I’ve seen enough wellness trends come and go to know that putting a few ingredients into a glass and giving them an impressive name doesn’t necessarily make them good for you.

Yet there’s still a part of me that wonders whether the latest concoction might work. It’s the same part of my brain that’s persuaded me to buy various supplements over the years, only to discover them lurking at the back of a kitchen cupboard six months later.

So when my husband, H, suggested starting the day with warm lemon water, cayenne pepper and Celtic sea salt, I was prepared to give it a go. We already had most of the ingredients, it would take a couple of minutes to make and Cyrus could help squeeze the lemons. I knew he’d enjoy that part, at least until Roblox offered something more entertaining than watching his mum experiment with breakfast.

H, of course, likes to take things further. His version includes apple cider vinegar, which he insists is an important addition. Mine doesn’t. I have a child to get to school, a job to do and a stomach that doesn’t appreciate being challenged before seven in the morning. Still, it seemed worth trying. I’ve spent a lot more money on things that promised to improve my health, so a few lemons and a pinch of pepper seemed a decent place to start.

According to some of the claims circulating online, lemon water with cayenne and Celtic salt can do almost everything. It supposedly boosts metabolism, improves digestion, supports hydration, flushes out toxins and helps burn belly fat. Depending on who you believe, it might even transform your energy levels.

That last promise caught my attention. Like many women dealing with perimenopause, I know what it’s like to wake up feeling tired despite having supposedly spent the night resting. Some mornings, my brain is ready to get on with things while the rest of me would prefer another hour under the duvet.

I wasn’t expecting miracles, but I was interested whether this combination might make my mornings a little easier. Or perhaps H and I had just found another way to make drinking water unnecessarily complicated.

Every morning for seven days, I made the drink using warm water, the juice of two fresh lemons, a small pinch of Celtic sea salt and a cautious shake of cayenne pepper. I say cautious because there’s only so much chilli I’m going to consume before breakfast. A little warmth is one thing, but feeling as though I’ve swallowed the contents of the spice cupboard is quite another.

There is some science behind the individual ingredients, although that doesn’t mean the combination delivers the benefits claimed for it. Lemons contain vitamin C, which helps the body absorb iron from plant-based foods when consumed together. Cayenne contains capsaicin, a compound researchers have studied for possible effects on appetite and energy expenditure. Salt provides sodium, which the body needs for fluid balance and normal muscle and nerve function.

None of it makes the drink a detox. Our liver and kidneys already deal with waste products, and there’s no convincing evidence that adding cayenne pepper and salt to lemon water improves that process. Nevertheless, I wanted to see whether I’d notice anything different over the week.

One of the attractions was the price. Lemons, cayenne pepper, salt and water were hardly going to make a serious dent in the household budget as we already had most of them in the kitchen.

I’ve spent enough money over the years on products intended to improve my health, appearance or general wellbeing. My gym membership is worth every penny because I actually use it, but there have also been supplements, skincare products and expensive gym leggings that promised more than they delivered. I’m particularly irritated by leggings that develop a hole between the thighs after a few months. Nothing ruins a perfectly good squat session quite like wondering whether the person behind you has had an unexpected view of your underwear.

Compared with all that, a homemade drink seemed sensible. No subscription, no special equipment and no need to explain another parcel arriving at the front door. What could possibly go wrong?

The first sip was exactly what you might expect. Sharp lemon, a faint salty taste and then the unmistakable heat of cayenne pepper. It wasn’t unpleasant, but I wouldn’t describe it as delicious either. It tasted rather like lemonade that had taken a wrong turn somewhere near the spice rack. I drank it before my coffee, which was quite an achievement. I love coffee first thing in the morning, and replacing that with warm, salty lemon water felt like a big concession to H’s enthusiasm.

Nothing remarkable happened. I didn’t experience a sudden burst of energy, feel mentally sharper or develop an overwhelming desire to clean the kitchen. I drank it, rinsed the glass and got on with rushing and getting everyone out of the house.

The only thing I could say with any certainty was that I’d started the day by drinking water. Hardly the most exciting result in the history of wellness experiments, but at least it was an honest one.

Over the next few mornings, I found myself looking forward to making the drink. Not because I’d noticed any major changes, but because I enjoyed the process. It felt good cutting the lemons, squeezing out the juice and standing in the kitchen for a couple of minutes before the day got going.

Cyrus occasionally helped with the juicing, although his enthusiasm remained greater than his interest in drinking the finished product. H continued adding apple cider vinegar to his version, while I continued to decline it. We’ve been married long enough to accept that we don’t have to agree on absolutely everything.

The cayenne gave the drink a definite kick, and I did feel more awake afterwards. But I’m not sure if that was my metabolism or the sensation of chilli hitting my tongue before I’d properly opened my eyes. What I did notice was that I was drinking more water in the morning. Instead of going straight to the coffee cupboard, I was starting with something different, and the routine was surprisingly easy to keep up with.

I also liked having a couple of minutes to myself before the usual demands of work and family took over. It wasn’t a grand act of self-care. I was standing in the kitchen squeezing lemons, not enjoying a spa weekend. But it was quite nice.

Seven days isn’t long enough to work out whether a drink has any meaningful effect on long-term health, and I wasn’t measuring anything scientific. This was an experiment in my own kitchen, not a clinical trial.

But a week was long enough to decide whether I enjoyed it and whether it was worth making again. On both counts, the answer was yes.

Cayenne is probably the ingredient responsible for much of the excitement surrounding this drink. It contains capsaicin, the compound that gives chillies their heat, and researchers have investigated whether it affects appetite, energy expenditure and fat oxidation.

Some studies suggest modest effects under certain conditions, but that doesn’t mean sprinkling cayenne into lemon water will produce meaningful weight loss. There’s no convincing evidence that it targets belly fat.

I can confirm that my midriff looked much the same at the end of the week as it did at the beginning. No reduction in belly fat, no sudden appearance of abdominal muscles and no need to buy smaller jeans. Admittedly, seven days would be a crazy amount of time in which to expect those changes, but that doesn’t seem to stop people making ambitious promises online.

I’ve spent years exercising, watching what I eat and occasionally wondering why my body doesn’t respond in quite the way I’d like. These days, I’m more interested in staying strong, enjoying my gym classes and having enough energy to get through the week than chasing the prospect of a flatter stomach.

I don’t want breakfast to become another opportunity to worry about my waistline. There are enough things demanding my attention without adding a daily assessment of whether my stomach looks any smaller. It’s also worth remembering that cayenne can irritate the stomach or aggravate acid reflux in some people. If it makes you uncomfortable, there’s no good reason to persevere.

Then there’s the salt. Not just any salt, as H is keen to remind me, but French Celtic sea salt, traditionally harvested from the salt marshes around Guérande in Brittany.

It sounds rather lovely, doesn’t it? French salt marshes, traditional harvesting methods and all those trace minerals. Celtic salt has developed quite a following in wellness circles, including among some of the sauna enthusiasts at our gym, where discussions about hydration can occasionally become surprisingly detailed.

The appeal is understandable. Celtic sea salt contains small amounts of minerals, but the quantities are generally too low to make it a meaningful source of most of them. Its main component is still sodium chloride, just like ordinary table salt.

Sodium is essential for fluid balance and normal muscle and nerve function, but most adults in the UK already consume more salt than they need. Unless there’s a specific reason to replace sodium lost through heavy sweating, adding salt to drinking water is generally unnecessary.

The NHS recommends that adults consume no more than 6g of salt a day, including the salt already present in food. People who need to limit their sodium intake should be particularly careful. I liked the faint saltiness, but I’m not convinced my body was receiving any extraordinary benefits from a pinch of something harvested on the French coast.

The lemons were the easiest part of the experiment to appreciate. They made the water taste fresh, provided vitamin C and gave me a reason to drink something other than coffee first thing in the morning.

Vitamin C supports normal immune function and helps the body absorb non-haem iron from plant-based foods when eaten together. That interests me because iron levels and fatigue have been part of my own experience of midlife health. It doesn’t mean lemon water treats iron deficiency, but it’s a useful reminder that ordinary foods can contribute to good nutrition without needing to be marketed as miracle cures.

There is one drawback. Lemon juice is acidic, and regularly exposing teeth to acidic drinks can contribute to enamel erosion. Drinking it with a meal or with a straw, rather than sipping it over a long period, and rinsing your mouth with plain water afterwards, can help reduce the risk. Two lemons also make a particularly sharp drink, so I’d probably use less juice next time.

I don’t need lemons to balance my body’s pH, cleanse my organs or give me the complexion of a woman who’s never experienced a sleepless night. I just like the taste, and that’s my reason to drink it.

There isn’t much to the recipe, although I’d suggest starting with less lemon and cayenne than I used if you’re trying it for the first time. My version was decidedly sharp, and making it stronger doesn’t make it healthier.

Squeeze the lemons into a glass, add the warm water and stir in the cayenne and salt. Taste before adding anything else, particularly more pepper. It should be pleasantly warming rather than something you have to endure.

There’s no established health advantage to drinking this combo on an empty stomach, and the added salt isn’t necessary for most people. Anyone with acid reflux, sensitive teeth or a medical reason to limit sodium may be better off sticking to plain water.

By the end of the week, I realised that the best part of the experiment had very little to do with the ingredients. It was the routine. Like many mums, I spend a surprising amount of time doing several things at once. There are school arrangements to remember, work messages to answer, meals to organise and the constant mental calculation involved in deciding whether I can fit a gym class into the day. Even when the house is quiet, my brain rarely follows suit.

Making the drink gave me a couple of minutes when I wasn’t doing anything important. I was standing in the kitchen squeezing lemons, which turned out to be quite nice. I know that sounds underwhelming, when the internet is full of people promising life-changing morning routines. But I’m increasingly fond of little habits that don’t take much effort or money. I don’t need another complicated wellbeing programme, especially one that involves downloading an app, monitoring my progress and feeling guilty when I inevitably miss a day.

Sometimes it’s nice to do something because you enjoy it.

Yes, I would. Not because I believe I’ve discovered a secret formula for weight loss, detoxification or eternal youth, and certainly not because I think Gwyneth Paltrow has been keeping the recipe hidden from the rest of us. I’d drink it again because the lemon was refreshing, the cayenne gave it a little kick and I liked starting the morning with water before moving on to coffee and the school run.

It hasn’t transformed my energy levels or changed my body shape. It hasn’t made me any more enthusiastic about household chores, and I can’t say I’ve noticed any great improvement in my concentration. But it has encouraged me to drink more water, and that is something I’m quite happy about.

H will continue adding apple cider vinegar to his version. I’ll continue leaving it out. It’s a small difference of opinion, and one I suspect our marriage will survive.

Four stars for affordability, convenience and the fact that I looked forward to drinking it by the end of the week. It loses a point for the exaggerated health claims surrounding it, although that is hardly the fault of the lemons.

Anyone suggesting that a glass of spicy lemon water will melt away belly fat, cleanse your organs or reverse ageing probably needs to sit down and have a word with themselves.

Absolutely, although we’re talking about the price of a few lemons rather than a serious investment in my future wellbeing. I like experiments that don’t require a financial recovery plan afterwards.

I’ll keep making it when I fancy something different in the morning, maybe with a little less salt and a slightly more restrained quantity of lemon juice. I’ll also continue drinking coffee, because I’m a reasonable woman and I know my limits. I’m no longer looking for a perfect body. I’m looking for habits that make living in this one a little easier. And if one of those habits involves squeezing a lemon before the school run, I’m quite happy with that.
