About the founder

Daniela Cyrulin 

Daniela Cyrulin is a functional nutritionist from São Paulo, Brazil. For 25 years, she has worked with people who want to feel better in their own bodies: more energy, deeper sleep, steadier health as the years go by.

  • University of São Paulo (USP) School of Public Health
  • Postgraduate degree in Functional Nutrition, FAPES
  • Specialization courses in supplementation and eating disorders
  • Registered with the Brazilian nutrition council: CRN 18.196

I'm Daniela Cyrulin, a functional nutritionist. I graduated from the School of Public Health at the University of São Paulo (USP), completed postgraduate training in Functional Nutrition, and have spent 25 years seeing patients, in person and online, from all over the world.

Over those years I took specialization courses in supplementation and began using supplements as an adjunct in my patients' care, always alongside dietary changes, meal plans, and lifestyle adjustments. What I learned is simple: no single thing does it. Not diet alone, not exercise alone, not mental health care alone. People live longer and better when all of it works together, and a well-chosen supplement can be one part of that.

I also consult for supplement companies in Brazil, developing their products. At some point it became clear that it was time to build my own: formulas I trust and already use with my own patients. In Brazil, I prescribe them through compounding pharmacies. Flowever is how I bring that same standard to the American market and help more people.

Every Flowever product starts with the question I ask in my practice: what does this person actually need, and what does the evidence say works?

Daniela has given talks at companies including Netflix, Syngenta, Viacom and Globo Condé Nast, and has shared her work in podcasts and publications such as Vogue, Harper’s Bazaar and Glamour. 

She also consults for supplement companies in Brazil on product development.

More than 300,000 people follow her work on Instagram and over 160,000 on TikTok, where she shares daily nutrition, sleep and longevity notes.

Our first product

Sleep Flow 

Good sleep is where healthy aging begins. Sleep Flow was created to support a nighttime wind-down routine, helping you fall asleep more easily, enjoy deeper, more restorative sleep and wake up rested. Our first formula, Sleep Flow, is built around three key ingredients:


Tart cherry

A natural source of compounds studied in relation to sleep quality


L-theanine

An amino acid from tea, studied for relaxation without sedation


Apigenin

The calming flavonoid chamomile is known for


Fresh tart cherries, an ingredient for sleep in Flowever Sleep Flow

About the formula

Crafted with intention 

At Flowever, every ingredient earns its place. We look beyond trends and choose ingredients for a reason, guided by science, function, thoughtful formulation and 25 years of clinical practice.

Lemon Balm Extract is widely studied for its calming effects on the nervous system. Its active compound, rosmarinic acid, supports healthy GABA activity to promote relaxation and restful sleep.

Tart Cherry Juice Concentrate provides compounds like natural melatonin, tryptophan, and anthocyanins. Together, they help support a healthy sleep cycle and improved sleep quality.

Sage Extract (Salvia officinalis) has been studied for supporting cognitive clarity and nervous system balance. This gentle support helps create the mental calm needed for restful sleep.

Passionflower is traditionally used to promote relaxation and calm, and is part of Sleep Flow’s blend for a soothing nighttime routine.

Fennel contains natural compounds such as anethole and fenchone linked to relaxation pathways in the body. Traditionally used in wellness practices, it helps support a soothing nighttime routine.

Chamomile has long been used as a natural sleep remedy across many cultures. Its compound apigenin supports GABA receptors to encourage relaxation and better sleep.

L-Theanine is a natural amino acid that promotes calming alpha brain waves linked to relaxation. This helps the mind unwind and supports easier sleep onset without sedation.

Our approach to natural sleep supplements starts with ingredients that have research behind them, like tart cherry and L-theanine, at doses that matter rather than token amounts. Every ingredient and every dose is on the label, with no proprietary blends.

Clean, purposeful formulas designed to support your healthspan, without unnecessary ingredients.

Wellness in every moment 

Wellness isn't a weekend retreat. It's how you sleep on a Tuesday. How you feel at 3 p.m. Whether your body is truly recovering or simply getting by.

After 40, good rest often gets harder to come by. Racing thoughts at bedtime, lying awake wondering how to fall asleep faster, waking up already tired. Learning how to calm your mind before bed is one of the simplest ways to protect your energy, your focus and your health as the years go by.

Flowever was created for everyday life—the real moments when what you put into your body matters most.

Quality and transparency

A good formula is only as good as how it's made.

Made in the USA

Produced in a cGMP-compliant, FDA-registered facility.

Tested for heavy metals

Every batch is tested before it reaches you.

Fully disclosed formulas

Every ingredient and every dose is on the label. No proprietary blends hiding the amounts.

Natural ingredients, chosen with purpose

Nothing is added without a reason.

Our philosophy
What guides Flowever
  • Family sharing breakfast after a restful night’s sleep
    Purposeful creation

    Every Flowever product begins with intention. We believe that thoughtful design and mindful development create products that do more than serve a function — they enrich daily life and support a balanced lifestyle.

  • Relaxed woman smiling at home in white clothes
    Elevating everyday rituals

    We believe that small rituals have the power to transform how we feel. Flowever products are designed to turn ordinary moments into experiences of relaxation, renewal, and self-connection.

  • Woman running across a city crosswalk
    Wellness as a lifestyle

    Wellness is not about perfection, but about consistency. Our products are created to integrate naturally into everyday routines, helping people cultivate moments of calm, care, and balance throughout their day.

  • What we stand for

    Our mission

    We believe living longer means little if we don’t live well. Our mission is to create thoughtfully formulated supplements that support the body through every stage of life — helping people feel better, function better, and build a longer, healthier healthspan.

    Our vision

    To redefine what it means to age well.
    A world where people don’t accept exhaustion, poor sleep, or declining vitality as inevitable parts of getting older — and where science-informed support helps close the gap between how we feel today and how well we could feel for years to come. Longer life. Better life. More life in your years.

    Our approach

    Every formula starts with a clinical question: what does this person actually need, and what does the science say works? From there, we choose ingredients by efficacy first — not by what looks good on a label.

    About Sleep Flow

    Sleep Flow is a thoughtfully formulated, multi-ingredient nighttime supplement designed to support relaxation and healthy, restful sleep.


    Its carefully selected formula combines Montmorency tart cherry concentrate, L-theanine, lemon balm, passionflower, chamomile, and sage in a melatonin-free formula.


    Rather than relying on a single ingredient, Sleep Flow takes a multi-ingredient approach to supporting your nightly sleep routine.

    No. Sleep Flow does not contain added melatonin.


    Instead, the formula combines Montmorency tart cherry concentrate, L-theanine, lemon balm, passionflower, chamomile, and sage to support relaxation and healthy sleep as part of your nightly routine.


    Sleep Flow takes a multi-ingredient approach to sleep support — without adding supplemental melatonin.

    Each serving of Sleep Flow contains:

    • 430 mg Montmorency tart cherry concentrate
    • 150 mg L-theanine
    • 200 mg lemon balm extract
    • 150 mg passionflower extract
    • 100 mg chamomile extract
    • 5 mg sage extract
    • 5 mg fennel seed extract

    The ingredients were selected based on their individual research backgrounds and traditional uses related to relaxation and sleep support.

    Sleep involves multiple biological and behavioral processes, so Sleep Flow was designed as a multi-ingredient formula rather than relying on a single compound.
    The ingredients have different research backgrounds related to relaxation and sleep support.

    Ingredients & Science 

    Montmorency tart cherry naturally contains melatonin and other bioactive compounds, including anthocyanins. Some clinical research has found potential improvements in sleep-related outcomes with tart cherry preparations, although results across studies are not completely consistent.


    Sleep Flow provides 430 mg of Montmorency tart cherry concentrate per serving.

    L-theanine is an amino acid naturally found in tea that has been studied for relaxation and sleep-related outcomes. Research suggests that it may support subjective sleep quality and sleep onset in some populations.


    Sleep Flow provides 150 mg of L-theanine per serving.

    Sleep Flow takes a different approach from melatonin alone.


    Melatonin supplements provide supplemental melatonin directly. Sleep Flow does not contain added melatonin. Instead, it combines Montmorency tart cherry concentrate, L-theanine, and a carefully selected blend of calming botanicals designed to support relaxation and healthy sleep.


    Rather than relying on a single ingredient, Sleep Flow takes a multi-ingredient approach to your nightly sleep routine.


    The right choice depends on your individual sleep needs and preferences.
