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.

Merck partners on intravaginal drug delivery device
Calla Lily Clinical Care has partnered with Merck to support the intravaginal drug delivery platform Callavid in an effort to improve how vaginal medicines are given.
The collaboration will continue development of Callavid, described as a leak-resistant device that addresses challenges with self-administered vaginal therapies.
Callavid uses a small, tampon-shaped device with an integrated absorbent liner. It is inserted, remains in place during drug absorption, then is removed.
The platform is intended for use with medicines in fertility treatment, oncology and hormone therapy. Administration via the vaginal route can prompt patient anxiety about positioning, dosing accuracy and leakage.
The partnership is the first industry collaboration for the Callavid technology, which was developed by Calla Lily Clinical Care.
Thang Vo-Ta, co-founder and chief executive of Calla Lily Clinical Care, said: “This collaboration with Merck marks an important milestone in the development of Callavid, our novel vaginal drug delivery platform.
“Merck’s scientific heritage and forward-looking approach to innovation make them an ideal partner as we work to address long-standing unmet needs in women’s health.
“By improving how vaginal therapeutics are delivered and experienced, Callavid has the potential to enhance both patient outcomes and quality of life.
“We see this collaboration as a meaningful step towards translating our technology into real-world clinical and patient impact.”
Calla Lily Clinical Care is seeking to develop what it describes as the world’s first drug-device combination product to prevent threatened miscarriage and for IVF luteal phase support, the phase after ovulation when the body produces progesterone to support early pregnancy.
The device is also being developed to deliver therapeutics for oncology, menopause, infectious diseases and live biotherapeutics to reduce repeated antibiotic use.
Dr Lara Zibners, co-founder and chairman of Calla Lily Clinical Care, said: “Our initial engagement with Merck through the Merck Innovation Challenge in October 2024 was an important moment of alignment around the need for more patient-centric innovation in women’s health.
“As both a clinician and a patient, I have seen how profoundly drug delivery can shape treatment experience.
“This collaboration builds on that early dialogue and reflects a shared interest in rigorously exploring new approaches that may improve how therapies are delivered and experienced by patients.”

Scaling startups risk increasing gender gaps, study finds
Rapidly scaling startups often make rushed hiring choices that disadvantage women, a recent study has found.
The findings draw on more than 31,000 new ventures founded in Sweden between 2004 and 2018.
Researchers at the Stockholm School of Economics report that in male-led startups, scaling reduces the odds of hiring a woman by about 18 per cent, and the odds of appointing a woman to a managerial post by 22 per cent.
Mohamed Genedy is co-author and postdoctoral fellow at the House of Innovation, Stockholm School of Economics.
Genedy said: “During those moments of rapid growth, even well-intentioned leaders can fall back on familiar stereotypes when assessing who they believe is best suited for the role.”
The patterns emerge even in Sweden, regarded as a highly gender-equal national context.
Founders with human resources-related education counteract these challenges.
In ventures led by founders with HR training, the odds of hiring a woman increase by more than 30 per cent, and the odds of appointing a woman to a managerial role increase by 14 per cent for the same level of growth.
Genedy said: “When founders have experience with structured hiring practices, the gender gaps shrink, and in some cases even reverse.
“This shows that getting the basics of HR right early on really pays off.
“When things start moving fast, founders with HR knowledge are less likely to rely on biased instincts and more likely to hire from a broader talent pool.”
Prior experience in companies with established HR practices also helps, though to a lesser degree.
It raises the likelihood of hiring women as ventures scale, but does not significantly affect managerial appointments.
The study additionally shows these patterns are not driven by founder gender alone.
Even solo female-led ventures display similar tendencies when growing rapidly, though to a somewhat lesser degree.
In female-dominated industries, rapid growth increases the hiring of women for regular roles but still reduces the likelihood that women are appointed to managerial positions.
“When scaling accelerates, cognitive bias kicks in for everyone. Female founders are not immune to these patterns,” said Genedy.
