For when balance shifts. And every day in between.
Microbiome-first female health
Your vagina is home to its own living microbial ecosystem.
In many healthy vaginal environments, beneficial Lactobacillus bacteria dominate, producing lactic acid and helping maintain the naturally acidic conditions that influence which microorganisms thrive.
And why does it matter? Because this ecosystem plays a significant role in vaginal health. Researchers are also exploring its relationship with reproductive health, fertility and pregnancy outcomes. What happens here may have implications far beyond what we've traditionally been taught about the vagina.
But ecosystems shift.
Periods. Sex. Hormones. Antibiotics. Pregnancy. Perimenopause. Menopause.
And the story doesn't stop at the vagina. Your gut is home to another extraordinary microbial ecosystem, with roles reaching far beyond digestion.
Two distinct ecosystems. One interconnected body.

The thinking behind everything we do.
Innate.
We start with what your body already knows.
Innate means building around ingredients your body already recognises. At the heart of it is our hero ingredient, lactoferrin: a protein your body makes itself, and one of nature's most remarkable.
Our hero ingredient
Lactoferrin is a naturally occurring protein that's already hard at work in your body. Found throughout the body, including the gut and female reproductive tract, it forms part of our innate defence system.
What makes it so special? Lactoferrin has been studied for its antibacterial, antiviral, antioxidant, anti-inflammatory and immune-modulating properties. From the vaginal microbiome to immunity and whole-body health, this extraordinary protein has inspired decades of scientific research, including more than 50 peer-reviewed papers.
200 mgElleferrin® lactoferrin in every capsule.
Discover pink gold →Intelligent.
Every ingredient earns its place through science.
Intelligent means nothing goes in without research behind it, and wherever possible, human clinical trials. With bacteria, that science lives in the strain.
Not all bacteria are created equal.
Even within the same bacterial species, different strains can have different characteristics, and the research on one cannot automatically be applied to another.
That's why we don't stop at the species name.
Our formulas use named, identifiable strains, so the research behind each one can be traced to the exact strain we use.
Because when you're talking about bacteria, specificity matters.
Meet our strains →Ours.
Female biology is the starting point.
Ours means formulas designed around the female body from day one, not adapted for it afterwards.
For too long, women's health has been treated as a variation on a default body. A smaller dose. A pinker pack. An afterthought.
So that's where we begin. Every formula starts with the female body and is built outwards from there.

10-Day Revival · L. rhamnosus CA15
10 days.
200 women.
CA15 has been studied in two randomised, placebo-controlled trials involving 260 women, at the same dose and duration used in 10-Day Revival. In the larger, double-blind trial, none of the women taking CA15 remained in the BV range by Nugent score after ten days, with the change maintained at 30-day follow-up.
Daily Magnificence · SYNBIO® IMC501 + IMC502
100% → 18%
In an open-label pilot study of 30 women, the proportion with a BV-range Nugent score fell from 100% to 18% after 15 days of the pairing at 5 billion CFU daily. In a separate 12-week double-blind, placebo-controlled trial in 50 adults, gut lactobacilli and bifidobacteria increased.
Every formula · strain-specific
6 named
strains.
Each live strain we use carries its own culture-collection identifier, such as DSM 33960 for CA15. That means the research behind each one belongs to the exact strain in the capsule, not to the species in general.
Research refers to the individual strains as studied, not clinical trials of the finished Daughters of Mars formulas.

From our founder
Daughters of Mars was founded by Lucy Hope from a fascination with the biology women are rarely taught about, and a belief that the products made for our bodies should be held to a higher standard.
From advanced materials and product innovation to the vaginal microbiome and lactoferrin, Lucy's work has been shaped by one question:
What could we create if we understood female biology better?
“Whether I'm creating something for myself, for the women I love, or for a woman I've never met who finds us somewhere on the other side of the world, the standard is the same. I have to believe it's worthy of her.”

Coming 2027
For nearly 100 years, menstrual products have remained largely unchanged, despite major advances in our understanding of female biology and the vaginal microbiome.
We're developing a next-generation, patented, bioactive-coated tampon designed with the vaginal microbiome in mind.
For bodies too often treated as an afterthought. For the biology only now beginning to be understood.
Women's bodies are not problems to fix.
They are extraordinary systems to understand.
Innate. Intelligent. Ours.
Womanmade. Female biology-first.
Know your biology.
Once dismissed as the vapours, women's experiences were explained away by everything from wandering wombs to hysteria. We're reclaiming the name, and replacing centuries of myth and misunderstanding with science, stories and a better understanding of female biology.
The vaginal microbiome is the community of bacteria and other microorganisms living within the vagina. In many healthy vaginal environments, Lactobacillus species dominate, helping maintain naturally acidic conditions. It's a living ecosystem that can change with menstruation, hormones, intimacy, antibiotics and different stages of life.
In many healthy vaginal environments, Lactobacillus bacteria help maintain naturally acidic conditions that influence which microorganisms thrive. Research has linked shifts away from Lactobacillus-dominant communities with bacterial vaginosis (BV), while scientists continue to investigate the vaginal microbiome's wider relationship with reproductive health.
Different formulas for different moments.
10-Day Revival is a focused ten-day vaginal microbiome course, built around a clinically studied strain at the dose and duration researched.
Daily Magnificence is our everyday vaginal and gut microbiome synbiotic, bringing together five named strains, lactoferrin, FOS and targeted micronutrients.
You can move from Revival to Daily, or choose the formula that best suits what you're looking for.
Lactoferrin is a naturally occurring iron-binding protein found throughout the body, including the gut and female reproductive tract. It forms part of our innate biology and has been studied for its roles in microbial interactions, mucosal health, immunity and iron regulation. Every Daughters of Mars capsule contains 200 mg Elleferrin® lactoferrin.
Because not all bacteria within the same species behave in the same way. Research carried out on one strain cannot automatically be applied to another. That's why our formulas identify the strains they contain, rather than relying on species names or impressive-sounding billions alone.
Our formulas are designed for oral use and may be taken alongside or following antibiotics. The timing of your capsules relative to antibiotic medication should follow advice from your healthcare professional and any final manufacturer instructions.
Both formulas are intended to be suitable during pregnancy, and Daily Magnificence is intended to be suitable during breastfeeding, subject to final product confirmation. Always check with your midwife, GP or healthcare professional before starting a supplement during pregnancy or breastfeeding.
