Interview: Alisa Vitti on female biohacking, Cycle SyncingⓇ and being an early femtech founder

Two decades ago Alisa Vitti began a mission to find alternative treatments for her newly-diagnosed PCOS. Now a global expert in functional nutrition, hormonal health and female biohacking, one the sector’s early founders talks to Femtech World.
When Alisa Vitti was diagnosed with PCOS in her early 20s, like millions of other women, she was told birth control was the only possible solution. Having had no cycle since the age of 12, she was overweight and suffering from painful cystic acne, depression, anxiety and hair loss. Her future looked bleak, if her doctor’s advice was anything to go by.
Studying at Johns Hopkins at the time, this diagnosis sent Vitti on a quest to find alternative options. Two decades on, out of this journey Vitti has become a renowned global expert and thought leader in functional nutrition and women’s hormone health, as well as a pioneer in female biohacking as the founder of one Flo Living, one of the very first femtech companies in 2012.
“I’ve been on a mission for the past 20 years to transform first line hormonal healthcare,” Vitti tells Femtech World.
“As a former PCOS sufferer myself, I saw first-hand how the conventional model of care falls short not only for women with hormonal issues, due to the lack of understanding of root causes of hormonal dysregulation, the long lead to diagnosis – an average of seven years – and the one size fits all approach to treatment, for example, ubiquitous prescribing of birth control as a solution.
“Struggling with my hormones had a profound effect on me and as a result I have been building all the tools I wish I had had at the time. I wanted to help myself and then I wanted to help every woman going through these issues.”
Infradian rhythms
Vitti’s early research led her to the discovery that women have a second biological clock— the infradian rhythm— which they experience over the course of their monthly cycle.
“It affects way more than your period,” she explains.
“It affects key systems of your body from your metabolism, brain, immune response, stress response, libido, fertility, and your cycle.”
Like the circadian rhythm, the internal clock that controls the sleep-wake cycle and other bodily functions over a 24-hour period, the infradian rhythm needs to be supported for it to perform optimally.
Men’s hormonal patterns are in sync with the circadian rhythm, Vitti explains, which is why so much of the way we live is based around this.
“The world is oriented around a circadian only clock when women also have an infradian rhythm and as you can appreciate how negatively impactful it would be to have your circadian clock disrupted daily, no one is appreciating the impact of having your infradian clock disrupted daily for years,” she continues.
“Women are not taught exactly how their hormones work and how to care for them from a young age and so they go decades actively disrupting their hormonal cycles.”
This, Vitti says, is one of the key contributing factors to why around 40 per cent of women (around 3.2 billion) globally are experiencing chronic hormone issues, such as PCOS, painful periods, irregular cycles, mood swings and infertility.
“Everything women have been told to do, from eating the same calories daily, to working out the same way daily, to waking up at the same time every morning is not only based on research done on men that actively excluded women, but fundamentally disrupts this infradian rhythm and causes all sorts of hormone issues that affect a woman’s cycle, immune response, stress response, brain and metabolic health,” she says.
“You have to change your self-care routine to match your changing hormones, while men need to keep theirs the same daily to match their hormonal patterns”
The Cycle SyncingⓇ Method
Based on her research, Vitti developed the trademarked Cycle Syncing Method, a groundbreaking diet and lifestyle programme that aims to leverage women’s natural hormonal patterns to improve their health and wellbeing.
The Method is based on three key pillars—diet, exercise intensity and time management— and aims to help women live in sync with their natural infradian rhythms, adapting their diet and lifestyle throughout each of the four stages of the cycle.
“Hormones are a byproduct of our endocrine system, which is elegantly complex, the best way to interact with and improve these hormonal outputs is by dietary and lifestyle interventions,” Vitti explains.
Her patented period app, MyFLO, goes one step further as a practical tool to help women implement the Cycle Syncing Method into their lives. It supports users to change their diet and calorie intake in order to optimise blood sugar stability and hormonal balance; adapt their workout type and intensity to optimise metabolism and fat use as fuel; and organise their calendar around each phase to reduce cortisol and stress.
According to her website, of those who have completed the Cycle Syncing Method, 70% have experienced weight loss, 85% experienced mood improvements, 83% reduced PMS Symptoms and 91% feel more energised.
“The benefits of using The Cycle SyncingⓇ Method are enormous,” Vitti says.
“You can keep your blood sugar more stable, reduce stress levels, boost oestrogen elimination, improve bowel movements and gut health, clear skin, eliminate all PMS symptoms, eliminate cramps, promote cycle regularity, experience better moods, better sleep, better sex drive, lose weight more easily, and boost your productivity. Everything works better in your body when you support your biological rhythm properly.”
The secret to success— without burning out
Vitti herself has lived by the Method for the last 20 years. She tracks her symptoms daily, preps her meals based on what her body needs that week, and arranges her schedule around times of the month when she expects to be feeling more creative or focused, for example. She credits it with not only transforming her health, but also being key to her succeeding in the way she has without burning out.
“It’s the reason I’ve been able to keep my PCOS in remission and to get pregnant at an advanced maternal age, and even to be going through perimenopause more slowly,” she says.
“It is also how I’m able to do as much as I do as an entrepreneur, mother, wife, friend, author, speaker without burning myself out. I compare it to a yoga practice, it’s not about being perfect, it’s just about coming back to the practice every day and being willing to try and learn more about my cycle phases and myself.”
Vitti adds: “For myself and for so many women who use this method, it has an added benefit of being a practice that heals a lot of the cultural conditioning we receive as women around body image, toxic hustle culture, while helping us reclaim our cyclical identity. It has been a method that has both physical and emotional benefits.”
Changing how women think about their health
Having generated over 500m views on TikTok alone, Vitti’s message— and the practical tools she has developed to deliver it— is resonating widely. With almost half of the female population suffering with symptoms which until now they have been told there is no solution for, it’s not hard to see why.
“Women have been left out of medical, fitness, and nutrition research – we have centuries to make up for in terms of catching up to understand how to best support women’s health from a healthcare perspective,” she says.
“I believe as research catches up, the new standard of women’s hormonal healthcare will include pharmaceutical interventions with dietary and lifestyle interventions, much in the same way cardiovascular medicine evolved to include both.”
Vitti adds: “In the meantime, the only way for women to navigate this environment is to biohack and become fully versed in their own health metrics so they can better manage their health.”
With two best-selling books under her belt, TedTalks and her work featured everywhere from Forbes and the NYTimes, to Vogue and Women’s Health, Vitti is empowering women with the tools to do just that.
A quick glance at the comments on her social media posts will squash any doubt that Vitti is changing the narrative when it comes to how women think about their health.

Juno Bio secures US$3.8m for precision diagnostics

Juno Bio has secured US$3.8m to expand its diagnostics platform for vaginal health and reproductive care.
The funding round was led by Ada Ventures, with participation from Artesian, Entrepreneur First and Illumina Accelerator.
The women’s health startup said the seed funding will support the launch of its first CLIA-certified sequencing laboratory in Oakland, California, and a new clinical vaginal microbiome and STI test for healthcare providers.
CLIA certification refers to US laboratory standards for testing human samples used in diagnosis, prevention or treatment decisions.
Dr Leighton Turner, co-founder and chief scientific officer of Juno Bio, said: “The vaginal microbiome is still one of the least understood systems in the body at a clinical scale.
“With our lab, we’re starting to build a measurement standard that clinicians can actually use.
“We believe the level of detail from this kind of testing can meaningfully improve how vaginal healthcare is provided.”
The company is developing precision diagnostics for vaginal health, where patients can experience recurring symptoms, inconsistent diagnoses and treatments based on trial and error.
Juno Bio said bringing testing in-house gives it greater control over the process, from sample handling to results, while allowing it to refine its technology and build what it says is one of the largest datasets focused on the vaginal microbiome.
The vaginal microbiome is the community of bacteria and fungi that naturally live in the vagina. Changes in this balance can be linked to infections, symptoms and wider reproductive health issues.
Juno Bio’s newly launched clinical test examines the wider vaginal microbiome and screens for four common sexually transmitted infections, or STIs.
Rather than looking for a single cause, the test is intended to give clinicians a broader picture of what may be contributing to symptoms.
Juno Bio says this matters because multiple infections can occur at the same time and microbiome changes may be linked to fertility, menopause or recurrent infections.
Dr Anna Powell of Johns Hopkins said: “Vaginal microbiome testing has the potential to significantly reshape how we understand and manage vaginal health, particularly for patients with recurrent or unexplained symptoms.
“While the field is still evolving, advances in sequencing and data interpretation are moving us closer to a future where more personalised, microbiome-informed care can complement existing diagnostic approaches.”
Check Warner, co-founding partner at Ada Ventures, added: “Juno Bio is setting a new standard for how vaginal health is understood and managed.
“What they’ve built at this stage, with this level of capital efficiency, is exceptional.
“We’re proud to support the team as they scale their clinical infrastructure and continue leading innovation in this critically underserved category.”

Women’s health draws record $1.55bn in equity as capital spreads beyond the mega-rounds

Women’s health companies raised a record $1.55 billion in disclosed equity in 2025, up 41 per cent year on year, according to W Group’s first Global Women’s Health Investment Report, The Road to the Era of Scale.
The report tracks over 500 funding stories and 164 equity rounds across 15 categories and 30+ countries.
Eighty-five companies raised equity in 2025, the highest single-year count on record. But according to the report, the headline figure isn’t the most significant one.
The bigger shift is in where that capital went and how concentrated it was at the top compared to the year before.
The report also points to a brand new investment category that didn’t exist twelve months ago.
SheMed closed a $50 million Series A this year to build a women-specific GLP-1 and metabolic health platform, the first dedicated raise of its kind.
Alongside the momentum, the report identifies one structural risk that could determine whether 2025’s growth holds: a bottleneck at Series A that’s leaving a number of promising seed-stage companies stuck.
Molly Taylor, head of content at W Group, said: “2025 was the biggest year women’s health has ever had, and the most important finding isn’t the headline number.
“It’s that the money has stopped pooling at the top.
“Capital is reaching more companies, more categories and more countries than ever before. The Era of Scale is real. It’s just not finished, and the Series A gap is where it could stall.
“Closing that gap is the highest-leverage move this ecosystem can make in 2026.”

Onto Health acquires diagnostics software company Levy Health

Onto Health has acquired Levy Health, a fertility software company providing precision diagnostics and patient intake for reproductive medicine.
The acquisition, fuelled by Onto Health’s US$20m Series A fundraise in April, supports its plan to build scalable, tech-enabled infrastructure for reproductive medicine.
Onto founder Roohi Jeelani, MD, called it the first of several moves in the company’s expansion strategy in a LinkedIn post, adding that there was “more coming soon”.
She said: “This isn’t just an acquisition, it’s proof of how we’re building Onto: physician-led, tech-enabled, and built to scale without losing the personal touch fertility patients deserve.”
Headquartered in Chicago, Onto Health combines evidence-based fertility care with artificial intelligence-driven diagnostics, clinical automation and longevity science.
AI-driven diagnostics use software to analyse patient information and support clinical decision-making, rather than replace clinicians.
Levy Health, founded in Berlin with US offices in San Francisco, helps medical providers identify endocrine disorders more quickly and helps clinics streamline fertility workups.
Endocrine disorders affect the body’s hormone system, which can influence ovulation, menstrual cycles and fertility.
Co-founder Caroline Mitterdorfer said joining Onto would expand Levy Health’s fertility care tools to more clinics and patients, helping physicians focus on patient care.
Onto opened its first clinic in Chicago in February, with plans for three more in the greater Chicago area.
The company said in April that it would use its new funding, led by Artis and Humania, to support additional operations in the US and expand into the Gulf Cooperation Council.
The Gulf Cooperation Council includes six Arab states bordering the Persian Gulf.
