This honest UK review of Happy Mammoth contains affiliate links.
If you’re female, have periods, or are going through the menopause, then it’s likely you’ve been targeted with Facebook ads for a brand called Happy Mammoth.
With dazzling reviews, impressive claims and slick branding, the supplements offered by this Australian brand seem, well – nothing short of miraculous.
This is particularly so for its Hormone Harmony formula. According to its users, this supplement promotes rapid weight loss, the cessation of nearly every hormone-related ailment, and leads to better moods.
‘I lost 29lbs in 2 months’, one review declares.
‘Just WOW!’ says another.
After being bombarded by ads for Happy Mammoth’s Hormone Harmony for a few weeks – and suffering with increased PMS symptoms since the birth of my son – I decided to give it a go. After all, the brand offers a 60 day guarantee. If the supplement did nothing for me, I could at least get my money back.
What was the harm in trying?
Twelve weeks later and below is my honest UK review of Happy Mammoth’s Hormone Harmony formula. Given that I haven’t come across any bad reviews of Happy Mammoth, I was keen to try them for myself – to see how I fared. Is Happy Mammoth worth it? Did the Hormone Harmony formula help manage my PMS? Are Happy Mammoth legitimate?
Below is my honest review – one you may find a little disappointing.
Are Happy Mammoth Legitimate?
Firstly, who are Happy Mammoth and are they a legitimate company?
In short, yes – Happy Mammoth are a very real and credible company.
According to the company’s own site, the brand was the brainchild of Matthew Murphy and founded in 2017. Initially, the company’s focus was on gut health and based around their bone broth, aimed at healing leaky guts.
From here, the company expanded – using natural, plant-based ingredients to create blends aimed at improving hormonal health. Trialling new plants and extracts, the Happy Mammoth team has also grown, and now includes nutritional scientists, a doctor and naturopathic physicians.
The brand now claim they are the only Natural Health and Nutraceutical company owned by Australians and – by any standards – are booming. To date, they have had over 1.6 million customers and their business grew by 300% in 2022 – 2023 (Facebook marketing at its best).
They are a now nine-figure women’s health brand.
I’d therefore say that Happy Mammoth certainly seem a reputable brand.
Where Are Happy Mammoth Based?
Happy Mammoth are an Australian company, but their products are now manufactured in the Netherlands, in accordance with EU safety standards.
What is Happy Mammoth’s Hormone Harmony Formula and How Does it Work?
While Happy Mammoth began life as a gut health company, it’s now largely synonymous with women’s health – specifically hormone regulation.
This is definitely the case with their flagship product – their Hormone Harmony blend. In fact, I would wager it’s this specific product that’s led to Happy Mammoth’s meteoric rise over the last twelve months.
So, what is Happy Mammoth’s Hormone Harmony and how does it work?
In short, this supplement is a blend of natural ingredients aimed at ‘balancing’ hormones. By doing this, Happy Mammoth claims it can reduce symptoms of the menopause, peri-menopause, PMS and any other hormonal related issues.
Its ingredients include: Ashwagandha (something I’ve previously used for anxiety), Wild Yam Root Extract (something that may increase the production of progesterone), Maca Root Extract (can help to balance hormones by treating the pituitary gland and hypothalamus) and Fennel Seed Extract (championed as a supplement to ease menopausal symptoms, through the production of estrogen).
Each ingredient is said to be optimally dosed, to ensure they have some genuine impact and are triple tested to ensure purity, quality and accurate quantity.
As a result, Happy Mammoth make some quite impressive claims regarding what you can expect when you take Hormone Harmony. These include:
- the reduction of bloating and fluid retention within 1 to 3 days
- uninterrupted sleep within 5 to 7 days
- the ‘shifting’ of hormonal weight within 15 to 30 days
- the elimination of hot flashes within 4 to 7 days
Forget HRT or the combined pill, it seems that Hormone Harmony will sort out your every hormone related woe.
How Much Does Hormone Harmony Cost?
One thing to touch upon in this honest review of Happy Mammoth Hormone Harmony is its cost.
This is not a cheap supplement.
Of course, any natural ingredient – triple tested for quality – tends to come with a price tag these days. If, as Happy Mammoth say, each ingredient is so rigorously tested, then perhaps a higher price tag is to be expected.
This said, one bottle of Hormone Harmony costs £54.99 for 72 capsules. Given that you are required to take three capsules a day, that means that each bottle will last you 24 days – or just over three weeks.
Three tablets therefore set you back around £2 a day.
It really isn’t cheap, is it?
To make things more manageable, Happy Mammoth do offer a subscription service – with two jars costing £49.99 each and 4 jars coming in at £44.99 each. If you hit ‘subscribe and save’ you’ll also receive an additional 10% discount.
However, if you don’t want the products anymore, you’ll need to remember to cancel the rolling billing cycle, or else they’ll continue to arrive.
Honest Review of Happy Mammoth Hormone Harmony: My Symptoms
So, with all the above pleasantries covered, let’s get onto the main act: my honest review of Hormone Harmony by Happy Mammoth.
Firstly, why did I decide to take this product?
As I’ve mentioned in previous blog posts, since having my son, my cycle has been an entirely different beast.
Prior to getting pregnant, my period – and cycle in general – was a complete non event. Apart from some irritable moods just before my period, I was genuinely entirely unaffected by my hormones. I was on a fairly even keel throughout the month and certainly didn’t notice my cycle dictating my mood, behaviours – or life.
Fast forward four years and all this has changed.
Getting pregnant and having a baby triggered something in my cycle; awakening a beast and setting in motion madly fluctuating hormones.
In short, my monthly cycle is now a rollercoaster of symptoms and emotions, with very little respite. Ovulation, the one time of the month I could depend upon to provide a glimmer of hope, is now filled with anxiety and, to boot, painful boobs.
My PMS is less of the angry variety and more a sobbing kind affair. And, once that finally ends, my period arrives – heavy and intense, and bringing with it night sweats, insomnia and bizarre ‘brain zap’ sensations.
My cycle has been so wild that I even looked into the possibility that I was already peri-menopausal. However, following a few blood tests, and given that I’m only 37, everything looked OK on that front (for now, at least).
(To test my hormones, I used the fantastic Hertility Health).
To try and therefore bring about a bit of equilibrium to my hormones, I began researching natural ways to balance hormones – and that’s when the adverts for Happy Mammoth began.
How Long Did I Trial Hormone Harmony For?
I started taking Hormone Harmony in January 2024 and trialled it for 12 weeks.
Given that Happy Mammoth claim you’ll notice changes within just a few days, I felt this was plenty of time to give this formula a fair shot. I also wanted to go through three full menstrual cycles, just to see if things improved as time went on.
Honest Review of Happy Mammoth Hormone Harmony: What I Liked
Let’s start this honest review of Happy Mammoth on a positive note, with what I loved about this supplement (and with it, the wider company).
Fast Shipping
Firstly, the lead time between placing my order and receiving my Hormone Harmony was incredibly short.
I’d expected to be waiting a little while, due to the fact it was coming from the EU, but it was on my doorstep within 48 hours.
I’d also ordered a few other Happy Mammoth supplements (including their formula for fatigue), and when it arrived I realised that some of the ingredients couldn’t be taken alongside the SSRI that I take.
I’d read a few bad reviews of Happy Mammoth regarding the returns process (i.e., there is none) and so I was a bit nervous about contacting them to arrange a refund. However, once I contacted Happy Mammoth Customer Services and explained the situation, they happily helped to facilitate the return (a quick note – the items had to be unopened and fully sealed).
I popped the fatigue formula back in the post and received my refund within five working days.
I’d say that I therefore had nothing but a positive experience with Happy Mammoth’s customer service and the returns process was seamless.
Premium Ingredients
When it comes to naturopathic supplements, it’s difficult to know whether the ingredients you are taking are – well, what they claim to be. With big brands such as Amazon now selling everything from menopausal supplements to insomnia remedies, it’s very difficult to gauge the legitimacy of the item you’ve bought.
Given Happy Mammoth’s strong emphasis on quality botanical ingredients, provided at a clinically-effective dose, I did feel reassured that these supplements were genuine – something certainly suggested by their fantastic reviews.
Happy Mammoth are also quality tested by a third party, ensuring their standards are upheld. Furthermore, and something I wanted to mention in this honest review of Happy Mammoth, is the fact that they don’t use any toxic fillers of flavourings to bulk out their products.
They are therefore GMO free, gluten free and contain no heavy metals – which is only a good thing.
No Side Effects
Does Happy Mammoth’s Hormone Harmony cause side effects?
No – not in my case, at least.
As I mentioned, I took Hormone Harmony for twelve weeks and had no negative side effects at all. Given that the formula is made from all natural, botanical ingredients, this is what I’d hoped would be the case. However, I do know people who have had adverse reactions to ingredients such as Ashwaghanda, so I was still a little bit nervous (especially as I also take a pharmaceutical drug – Sertraline).
However, I’m pleased to report that it all went without a hitch – something that’s perhaps down to the company’s dedication to quality ingredients.
My Honest Review of Happy Mammoth Hormone Harmony: What I Didn’t Like
Now, onto the stickier part of this honest review of Happy Mammoth Hormone Harmony – what I didn’t like about this product.
The Quiz
Firstly, Happy Mammoth suggest that there is an element of personalisation to their service, in the form of an online questionnaire (or ‘free assessment’). You can take this two minute test and, apparently, find out which Happy Mammoth product will ‘change your life’.
It goes on to claim that by taking this quiz, you’ll be offered ‘100% personalised results’ based on over ‘14,000 scientific studies’ from the likes of Harvard, Yale and Columbia university.
This all sounds great, but what exactly does it mean? That these universities are having input into your final results, or advising what supplements to take? That the team at Happy Mammoth have read all 14,000 of these studies and are now applying them solely to me and my symptoms?
I very much doubt it. If I’m honest, claims like this just seem to be sales-driven word soups, that attempt to put additional legitimacy behind products.
The questionnaire itself is very simple – four questions in total. From it, I doubt anyone could gain any real insight into my symptoms, let alone be able to offer a personalised approach to my ‘treatment’.
The answer I received also seemed to glide over the fact I reported digestive issues and mental health issues (as an aside, if you are being sold a herbal supplement to help manage your mental health, then that’s a considerable red flag in my opinion). There were no additional directions for anyone reporting mental health symptoms (e.g. to contact your GP) and instead it was all wrapped up with a sales pitch.
My issue, it claimed, was that I was being overrun by estrogen and need to ‘rush’ it out (I presume this is a typo and they mean ‘flush’). ‘Based on your results’, Happy Mammoth said, ‘it sounds like your body may be overflowing with the hormone, estrogen, and struggling to metabolise it’.
And all that from four questions? That’s some impressive diagnostic medicine.
Their solution, of course, was their best-selling Hormone Harmony formula.
This diagnosis was then reinforced by a spammy, sales-driven email, apparently from Happy Mammoth’s CEO – Matt. This again reiterated that my body was drowning in estrogen and for a limited time only, I could use a Happy Mammoth discount code – for 15% to remedy this.
‘We rarely offer discounts, because Hormone Harmony is our top bestseller’, the email said. In other words, just another cliche sales tactic that – for me at least – undermines the sincerity of this company.
This first interaction with Happy Mammoth, and their quiz, therefore raised (for me, anyway) some serious red flags.
Their unsubstantiated claims of 14,000 studies supporting my (apparently) personalised diagnosis, the hyperbolic language, the brevity of the questionnaire and the lack of proper safeguarding around mental health symptoms, all suggested that this was a company underpinned by a hard sales business model, rather than any meaningful pastoral care.
This is something I wanted to definitely touch upon in this honest review of Happy Mammoth and their Hormone Harmony formula.
In short, it gave me the ick.
Advertising and Facebook Marketing
I first came across Happy Mammoth on Facebook, where I seem to have been targeted for incessant adverts.
Aged 37, a mother, and – well, female – it seems I fit their key audience and as such, my Facebook feed could not move for their ads. Given the volume of adverts I saw, I can only presume that they have some serious budget behind this campaign.
Initially, I was intrigued by their adverts. As I said, I was looking for natural remedies to help support my hormonal health and Happy Mammoth seemed to deliver on this. However, as the adverts increased, their choice of language, grand claims and liberal use of ‘statistics’, began to irk me.
One advert I saw claimed that Happy Mammoth could clear up ‘those past few years of craziness’ – as it pushed their menopause supplement on me.
Now, there’s a lot to unpack here.
‘Years of craziness’? For a company that claims to be dedicated to women, their hormonal health and their wellbeing, this language is incredibly patronising, dismissive and, dare I say it, sexist.
Peri-menopausal or menopausal women are not ‘crazy’; they are dealing with very real, often debilitating symptoms. Referring to them as such only reinforces old tropes about menopausal women and does absolutely nothing to positively push the new, proactive language and narrative around this stage of a woman’s life.
For a company concerned with women’s health, this sort of language is incredibly disappointing. In fact, it made me feel a bit angry.
Depressing Focus on Weight Loss
Secondly, Happy Mammoth’s adverts seem less focused on helping women to genuinely manage their menopause symptoms, or their ‘hormone imbalances’, and instead push their apparent weight loss potential.
This is something I wanted to touch upon in this honest UK review of Happy Mammoth – as I believe it’s a focus that undermines much of this company’s legitimacy.
Firstly, this dated approach to women’s health, focusing only on the weight, is depressingly regressive and targets women’s self-esteem and insecurities. Secondly, there is no real evidence (that I can see) to suggest that their products help women to safely lose weight, or sustain this weight loss.
Much of Happy Mammoth’s language instead focuses on ‘flushing out weight’. If this is the case, then what they are referring to is water retention – not visceral fat, which is so often found around our waists and can be the result of hormones (particularly cortisol).
This sort of fat cannot be ‘washed’ out of our systems, it can only be lost through fat burning and a calorie deficit – induced by exercise and improved diets.
When Happy Mammoth therefore claim that women have lost up to 30lb in 2 months from their supplements, or that 99% of women declared that the ‘hormonal weight’ around their waists had simply ‘disappeared’, I remain highly skeptical.
I had a careful look at what Happy Mammoth suggest helps to prompt this miracle weight loss, specifically within their Menodaily supplement. It seems that much of the focus is on its key ingredient – Kelp, with footnotes (apparently) providing the research behind this.
However, once you scroll down to the footnotes, many of them seem to be in no real order and some do not link to scientific research, but just online websites like Healthline.
While Kelp has been linked to its potential role in weight loss (thanks to the fact it contains iodine, which supports our thyroid function), results remain inconsistent. In fact, one study that looked at the effects of taking daily kelp found that it had absolutely no effect on women’s weight, fat composition or blood pressure.
When it comes to Happy Mammoth and weight loss, I’d therefore tread very carefully. If something seems to good to be true, it often is.
Unbacked Claims and Statistics
Another thing to mention in this honest UK review of Happy Mammoth are their allusions to academic research.
First thing’s first, there is no evidence that any of their supplements, including Hormone Harmony, have been subject to any clinical trials. There are no references to them in PUBMED and their own reviews remain purely anecdotal.
However, Happy Mammoth do use a little creative licence to get around this, by giving the impression that their formulas have been cited in various publications, including The New Yorker, Forbes and Scientific American. Yet, when you look again – they are simply referring to the fact the ingredients in their supplements have, on an occasion, been mentioned in these publications.
It doesn’t say why, or for what – nor does it show clinical results. These references are therefore largely worthless, and simply a sign of clever marketing and embellishment.
Happy Mammoth is not FDA Approved
Scroll down to the bottom of Happy Mammoth’s website and you’ll see the following disclaimer: ‘The statements made on this website have not been evaluated by the FDA (U.S. Food & Drug Administration). The products sold on this website are not intended to diagnose, treat, cure, or prevent any disease.’
Again, given the language found throughout Happy Mammoth’s own website, this is a surprising admission. Indeed, their quiz doesn’t only seem to offer a diagnosis (remember my body, overflowing with estrogen?), but they seem to claim that they can completely treat and cure almost any hormonal related issue.
In fact, one of their adverts even said that their supplements will ensure you ‘sale through’ the menopause. That is quite the assertion.
Given that Happy Mammoth’s products are not peer reviewed nor FDA approved, I would again take their messaging with a pinch of salt.
Hormone Harmony Didn’t Work (For Me)
Lastly, and the most critical part of this honest review of Happy Mammoth Hormone Harmony: did it work for me?
No, not really.
As I mentioned, following the birth of my son (and still some three years later), my cycle is a white-knuckle ride. I struggle with bloating, mood swings, anxiety, fatigue, dry skin, heavy periods and constant brain fog – something that really does impact my life.
According to Happy Mammoth, this was (according to my four answers) down to estrogen dominance – something that could be entirely remedied by their Hormone Harmony formula. Apparently, the ingredients inside this supplement would work ‘uniquely’ with my own body – going where the need was greatest. I didn’t receive – or even need – a specific diagnosis, as this magical supplement would apparently instinctively know what to do.
It was a one size fits all approach to hormonal health.
Yet it didn’t seem to fit my overflowing, oversized hormones – at all.
Honestly, and having taken Hormone Harmony for twelve weeks, I can confidently say it did nothing for me and I didn’t notice any benefits.
Despite claims my ‘hormonal weight’ would ‘shift’ within 15 to 30 days, I weighed exactly the same at the end of my 12 weeks. I still remained just as bloated and my sleep was exactly the same, if not worse.
It was all a bit disappointing.
My Honest UK Review of Happy Mammoth Hormone Harmony: The Verdict
Happy Mammoth are a company clearly doing something right.
Their sales are soaring, their reviews are glowing and they have enough budget to fund a near non-stop social media advertising campaign.
Furthermore, it does seem that they are genuinely interested in providing naturopathic solutions to women; seeking to find high quality, dependable and effective ingredients to support women during difficult times in their lives.
However, and for me at least, Happy Mammoth and their Hormone Harmony was a let down.
Of course, I did suspect that this might be the case. Much of their language, and so many of their claims, simply seemed too good to be true; all talk but no trouser. Much of their business seems to be built on clever marketing, manipulative language and targeting women where it hurts – their hormones and their weight.
While I have no doubt women have had real success with these supplements – and I remain convinced that plant-based ingredients can have tremendous effect on our health – I do believe Happy Mammoth are perhaps capitalising on this somewhat; declaring their supplements the magic bullet that simply does not exist.
Hormoens are complicated, nuanced and inextricably linked to a woman’s personal health, environment, genetics and wellbeing. There is no one size fits all approach to ‘balancing’ hormones, nor eradicating menopausal symptoms.
The fact that Happy Mammoth suggest that there is, and it is found inside their products, is therefore worrying.
Ultimately, and as much as it pains me to admit, from my experience it seems that Happy Mammoth is simply a case of the Emperor’s New Clothes. Sure, it may help you – and it seems it has helped thousands of others – but please don’t be disappointed if you find that it does very little.
