“After just a few weeks of taking monthlies I’ve noticed a significant improvement in how I feel during my cycle. The cramps that used to keep me curled up on the couch are now much more manageable, and the bloating I dreaded every month has drastically reduced. I also have fewer mood swings and way more energy, even during my toughest days.”

"I’m just finishing my second month and I can only say that my symptoms have reduced dramatically. After quitting my birth control pills, my pain got back and I needed to take painkillers all the time. To be honest, I completely lost faith that something else could help. I can only say, very worth the price. Thanks monthlies for bringing my life back!"
Verified Buyer
Claudia Y.
“I’ve been using monthlies and am beyond impressed. For years, I thought period pain was something I had to live with—it disrupted my life so much that even basic tasks felt impossible. Now, not only is the pain completely gone, but I also feel more energized, sleep better, and notice improved performance in my daily life. It’s amazing to finally live without suffering. Highly recommend!”

The Science
What’s Behind Period
Bloating & Weight Gain?
The bloating, puffiness, weight gain, and cravings in the week or two leading up to your period are not just your imagination.
They’re signals from an overreacting Hypothalamic-Pituitary-Ovarian (HPO) axis, your body’s hormone command center.
The worst part? The HPO axis is easily overstimulated by stress, poor sleep, nutrient gaps, and everyday exposures like plastics. A 2024 Harvard-led study found that many UK women had at least 5 major nutrient gaps, making balance even harder to maintain.*
This can lead to:
1. Fluid retention
You feel puffy and bloated before your period starts, with a belly that won’t fit into your favourite clothes. This discomfort is tied to the pituitary gland, which can overreact to hormonal shifts, causing water retention and swelling.
2. Digestive sluggishness
"Your stomach feels heavy and uncomfortable, with persistent gas and bloating regardless of what you eat. This is often linked to the hypothalamus and inflammation, which influence digestion and can overreact to stress or hormonal changes, leaving you feeling off balance.
Most debloating products only address surface symptoms, leaving the root hormonal imbalances untouched. That’s why the bloating and weight keeps coming back.
After personally working 1-on-1 with over 2,500 women aged 18 to 45, five leading women’s health experts uncovered a natural solution that not only targets the root cause of bloating and weight gain but helps restore systemic balance for long-term comfort, more predictable results

The Solution
Science-based,
predictable comfort
monthlies is the first supplement to target both the symptoms and the root cause to provide relief that’s predictable, lasting, and complete.
Targets Symptoms
1. Gentle Debloat
Monthlies eases hormonal bloating with ginger and aniseed, which are known to calm gas and digestive discomfort while supporting a relaxed gut, helping you feel lighter and more at ease after meals.*
Magnesium supports motility, helping to ease the tight, stretched feeling that makes clothes uncomfortable, while turmeric and lemon balm are known for their calming properties, assisting in reducing puffiness and water retention.*
Soothes Systematially
2. Balances Your HPO
Monthlies tackles the root causes of hormonal bloating by supporting the HPO axis for balanced fluid regulation, digestion, and metabolism — so you can enjoy a flatter tummy without restrictions or unexpected swelling.
Myo-inositol and flaxseed help stabilise prolactin and estrogen levels, easing the puffiness and heaviness you feel before your period.
Broccoli sprout extract supports estrogen metabolism and detoxification, maintaining HPO harmony, while B-vitamins and zinc optimise digestion and fluid balance — so you can enjoy smoother cycles and feel confident knowing bloating won’t keep coming back.

The first supplement to
support your HPO axis & bring
symptomatic comfort
monthlies is the first formula to feature 26 science-backed ingredients selected by our female doctors to target both the symptoms and the root cause to provide ease that’s predictable, lasting, and complete:
Reduce Period Pain*
Cramping happens when prostaglandins cause your uterus to contract. More prostaglandins = more intense pain.
monthlies supports your HPO axis with myo-inositol, flaxseed, and broccoli seed extract to promote hormonal balance and lower prostaglandin activity.
Ginger, aniseed, and turmeric have been shown in studies* to provide targeted ease from pain and inflammation (hello natural comfort!) without the downsides of painkillers.

Our experts cracked the
code for women who had
“tried everything”
First, we personally helped
thousands of women who had “tried
it all” find relief from cycle struggles
After helping over 2,500 women over a decade, we realised there wasn’t a product that addressed the root cause of menstrual symptoms while offering targeted support.
So, we took everything that worked and crafted it into one simple, once-a-day, delicious drink - monthlies.

“It’s astonishing how many women believe period pain is normal and ‘just part of being a woman.’ When women think of health, they often focus on weight, digestion, or skin, but rarely on cycles. monthlies takes a fresh approach by prioritising menstrual wellness, helping women understand their cycles while supporting their bodies to restore balance naturally.”

What to expect
Your first cycle
What to expect:
In the first cycle, your body starts replenishing key nutrients, supporting steadier energy, better sleep, and a more balanced mood. Early hormonal adjustments can also begin easing bloating and digestive sluggishness, as oestrogen metabolism and fluid regulation start to normalise. These initial shifts set the stage for deeper hormonal recalibration in the coming months, as your body regulates through complex endocrine feedback loops.*
We've accounted for
periods as a whole
Carefully picked by women’s health experts, monthlies features premium, third-party tested ingredients in their most active and highly absorbable forms — ensuring purity, potency, and unmatched quality.
To fit all 26 ingredients in pill form, you'd need to take 16 pills a day. monthlies is the simplest, safest, and most effective way to ensure you're getting everything you need — for less than £1.30 per day at the lowest.
Simply mix one scoop of monthlies into water in the morning, and you’re good to go!
Plant Extracts
Lemon Balm
Lemon balm has been shown to promote relaxation and reduce stress by modulating mood and cognitive function. It may exert calming effects on the central nervous system, potentially through its influence on GABAergic activity.*
Helps: Promotes a calm mood, supports relaxation, and aids in managing occasional bloating.*
Broccoli Seed Extract
Broccoli seed extract contains glucoraphanin, which metabolizes into sulforaphane. Sulforaphane influences estrogen metabolism by promoting a favorable 2:16 hydroxyestrone ratio, supporting hormonal detoxification and balance.*
Helps: Encourages hormonal balance, supports estrogen metabolism, and promotes comfort during hormonal fluctuations*
Flaxseed
Flaxseed is rich in lignans, which act as phytoestrogens. These compounds may help modulate estrogen levels, support progesterone balance during the luteal phase, and improve menstrual cycle regularity. Additionally, flaxseed may help manage weight swings and reduce cravings and appetite fluctuations associated with hormonal changes. The high fiber content in flaxseed promotes satiety, potentially leading to decreased calorie intake and better appetite control.*
Helps: Supports hormonal balance, aids in managing occasional bloating, promotes menstrual cycle comfort, and may assist in weight management by reducing cravings and appetite fluctuations.*
Ginger Root Extract
Ginger contains bioactive compounds like gingerols and shogaols that inhibit prostaglandin synthesis via COX and LOX pathways. This anti-inflammatory action helps reduce menstrual cramps and digestive discomfort.
Helps: Aids in managing occasional cramps, supports digestive wellness, and promotes natural cycle comfort.*
Aniseed Extract
Aniseed has carminative and antispasmodic properties that relax gastrointestinal muscles, alleviating bloating, cramps, and other digestive discomforts.
Helps: Promotes soothing comfort during cyces, supports digestion, and eases occasional tension.*

FAQS
How fast will I see results?
Most women notice improvements in energy, mood, and digestion within the first few weeks. Because hormones operate on intricate feedback loops, more significant changes, like potential ease from cramps or bloating, often require 2-3 cycles. This allows monthlies to work with your body’s natural rhythms for lasting results.
What is the HPO axis, and why is it important?
The HPO axis stands for the Hypothalamus-Pituitary-Ovarian axis, and it’s like your body’s hormonal command centre. Here’s how it works:
Hypothalamus (The Coordinator): This part of your brain sends out signals (called GnRH) to kickstart hormone production. It’s also highly sensitive to stress, sleep, and nutrition, which can disrupt the entire process.
Pituitary Gland (The Messenger): The pituitary gland receives signals from the hypothalamus and produces key hormones like FSH (follicle-stimulating hormone) and LH (luteinizing hormone). These control your cycle rhythm and regulate things like water retention and sugar metabolism.
Ovaries (The Hormone Producers): Your ovaries respond to the pituitary gland’s signals by producing estrogen and progesterone. These hormones are responsible for managing symptoms like cramps, mood swings, and bloating, as well as regulating prostaglandins, which can cause pain during your period.
When this system is in balance, your body works smoothly. But when it’s thrown off by factors like stress, nutrient gaps, or lifestyle changes, the feedback loops misfire. This can cause your body to overreact, leading to bloating, pain, mood swings, fatigue, and other cycle-related symptoms.
When and how should I take monthlies?
Take monthlies once daily in the morning with food. Simply mix one scoop with water or your favourite beverage. Consistent use is essential to experience the full benefits, as it works with your body’s natural cycles.*
What if I only struggle with X but not Y or Z?
monthlies is designed to address both current symptoms and long-term hormonal health. Many women report feeling more balanced, energetic, and focused within weeks, even if they initially only struggled with one or two “main” symptoms. Its targeted nutrients also work to prevent future flare-ups or new issues from arising, supporting overall well-being.*
Can I start taking it at any point of my cycle?
Yes, you can start taking monthlies at any point in your cycle.
What does the 90-day guarantee mean?
Most women notice an energy boost from Monthlies within days, then experience fewer and less intense cramps, less bloating, more stable moods, and better sleep during their second cycle after starting. Some feel these changes sooner, others might take a bit longer - as every woman's cycle is unique.
That's why we encourage you to try it yourself. If you don't feel more energized and in control, with less bloating and pain, you have 90 days to claim a full refund of your first order. Simply email us at returns@withmonthlies.com without giving any further reason.
Can I take monthlies if I use birth control?
While you can certainly take monthlies powder for its potential benefits, it's important to note that hormonal contraceptives, such as implants and pills, can affect hormone levels.
Since hormonal contraceptives regulate your hormone balance, the efficacy of the powder might be compromised by the contraceptive method you are using.
