Benefits

Oval supports estrogen levels. Benefits of estrogen include:

Clearer Mind & Steadier Mood: Supports memory, focus, and emotional balance

Healthier Weight: Supports a leaner, more comfortable body and helps prevent midsection weight gain

Glowing Skin: Promotes firmer, smoother, more radiant skin

Thicker, Shinier Hair: Supports fuller, healthier-looking hair

Restful Sleep: Supports deeper sleep and stable nighttime temperature

Sexual Wellness: Increases comfort, natural lubrication, and sex drive

Stronger Bones & Heart: Supports long-term bone and cardiovascular health

Who is Oval for?

Oval is made for women in their 30s, 40s, 50s, and beyond who want to support their mood, mind, metabolism, skin, hair, sex drive, sleep, and long-term health during perimenopause and menopause. It’s also a good choice for women who cannot or prefer not to use hormone therapy.

How does Oval work?

Oval supports a part of the gut called the estrobolome—the network of bacteria that helps recycle and regulate estrogen. By boosting this natural process, Oval helps maintain steadier estrogen levels while also supporting digestive and metabolic health.

Why is Oval subscription-only?

Hormonal balance takes time and consistency. Oval works best when taken daily, so a subscription ensures you never miss a dose.

Why a 3-month supply?

Clinical studies showed measurable results after 12 weeks of use. A three-month plan gives your body the time it needs to restore estrogen balance naturally.

Benefits of Steady Estrogen Levels

By boosting collagen and follicle health, estrogen keeps skin firm and glowing while promoting thicker, shinier hair.

Estrogen regulates insulin sensitivity and fat distribution, helping to reduce midsection weight gain and improve metabolism.

Estrogen fuels neurotransmitters that improve memory, reduce brain fog and increase control over mood swings.

Estrogen helps regulate your internal clock and stabilize nighttime temperature, supporting deeper, more restorative sleep.

Estrogen supports vaginal tissue health and natural lubrication, supporting comfort and sex drive through midlife.

Estrogen maintains bone density and supports healthy joints, reducing the risk of osteoporosis and improving mobility as you age.

Estrogen maintains healthy cholestrerol ratios and blood vessel elasticity, promoting cardiovascular function.

How Oval Works

How Oval Works

1.

Produces a natural enzyme

Probiotic strains in Oval make beta-glucuronidase, which helps unlock estrogen stored in your gut.

2.

Sustains estrogen levels

Once unlocked, this estrogen can be naturally reused by your body to sustain healthy levels.

3.

Feel like yourself again

Estrogen supports the systems that make you feel like you—your mood, energy, and confidence.

What is a gold-standard clinical trial?

A gold-standard clinical trial is a randomized, double-blind, placebo-controlled study—the most rigorous way to test whether a product truly works. Participants are randomly assigned to receive either the active product or a placebo, and neither they nor the researchers know who gets which until the study ends. This design eliminates bias and ensures reliable, scientific results.

We started with estrogen because it touches nearly every aspect of our wellbeing—from energy and mood to skin, hair, sleep, sex, and weight. Our mission is to deliver science-backed tools that help women navigate midlife with confidence and ease.

FAQs

Why Oval?

Oval is a daily probiotic designed to support your body’s own estrogen balance during perimenopause and menopause. Rather than adding hormones, it works through the gut microbiome to help your body maintain natural hormonal stability—supporting mood, metabolism, skin, hair, sex, sleep, and long-term health.

What Are The Benefits?

Oval supports steady estrogen levels. Benefits of maintaining estrogen as you age include:

Clearer Mind & Steadier Mood: Supports memory, focus, and emotional balance

Healthier Weight: Supports a leaner, more comfortable body and helps prevent midsection weight gain

Glowing Skin: Promotes firmer, smoother, more radiant skin

Thicker, Shinier Hair: Supports fuller, healthier-looking hair

Restful Sleep: Supports deeper sleep and stable nighttime temperature

Sexual Wellness: Increases comfort, natural lubrication, and sex drive

Stronger Bones & Heart: Supports long-term bone and cardiovascular health

Who is it for?

Oval is made for women in their 30s, 40s, 50s, and beyond who want to support their mood, mind, metabolism, skin, hair, sex drive, sleep, and long-term health during perimenopause and menopause. It’s also a good choice for women who cannot or prefer not to use hormone therapy.

Does it contain hormones?

No. Oval’s Estrogen Support Probiotic is completely non-hormonal. It doesn’t contain estrogen or alter your hormone production—it supports your body’s natural ability to recycle and balance its own estrogen.

Can I take it with hormone therapy (HRT/MHT)?

Yes. Oval is safe to take alongside HRT/MHT and can complement it. Many women use Oval before, during, or after hormone therapy to support gut health and healthy estrogen metabolism.

Is it safe to take every day?

Yes. Oval’s probiotic strains are clinically studied, well-tolerated, and safe for long-term daily use. Because it’s non-hormonal and microbiome-based, it supports both hormonal and digestive health naturally.

Why is Oval Subscription-Only?

Hormonal balance takes time and consistency. Oval works best when taken daily, so a subscription ensures you never miss a dose.

Why a 3-month supply?

Clinical studies showed measurable results after 12 weeks of use. A 90-day plan gives your body the time it needs to restore estrogen balance naturally.

How does Oval work?

Oval supports a part of the gut microbiome called the estrobolome, the community of bacteria that help regulate and recycle estrogen. By restoring this natural process, Oval helps maintain steadier estrogen levels and smoother hormonal transitions while also supporting digestion, metabolism, and overall well-being.

What is the estrobolome?

The estrobolome (pronounced ESS-tro-bo-lome) is the group of gut bacteria that help regulate how estrogen is processed in the body. These bacteria produce enzymes that reactivate estrogen so it can be reabsorbed and reused instead of being lost. When the estrobolome becomes less active, as often happens during perimenopause and menopause, more estrogen is excreted, contributing to symptoms like hot flashes, mood changes, and fatigue. Supporting a healthy estrobolome helps your body maintain a more balanced hormonal environment naturally.

What is beta-glucuronidase?

Beta-glucuronidase (pronounced BAY-tuh gloo-kyoor-ON-ih-dase) is an enzyme made by certain gut bacteria that helps reactivate estrogen in the body. When estrogen is processed by the liver, it is often bound for excretion; beta-glucuronidase releases that bound estrogen, allowing it to be reabsorbed and recirculated naturally. This recycling process is one of the estrobolome’s key roles in maintaining hormonal balance.

Is Oval clinically studied?

Yes. The probiotic strains in Oval’s formula have been evaluated in two randomized, double-blind, placebo-controlled clinical trials with more than 300 women. Women taking the probiotic blend maintained healthier estrogen levels and experienced improvements in hot flashes, sleep, fatigue, and mood after 12 weeks of daily use.

Is it possible to quantify the effect of estrogen recycling?

Yes, indirectly. Researchers measure how efficiently the body recycles estrogen by looking at changes in circulating hormone levels, especially estradiol (E2), after interventions that influence the gut microbiome. In clinical studies, women taking Oval’s probiotic blend maintained 62% higher estradiol levels compared with placebo after 12 weeks, suggesting measurable support for natural estrogen recycling.

When will I start to feel a difference?

Every woman’s body is different, but many begin noticing changes, like better sleep, improved mood, or increased comfort, within 6 to 8 weeks. In clinical studies, measurable benefits were seen after 12 weeks of consistent use.

How do I take it?

Take one capsule daily with food or as part of your morning routine. The key is consistency—it works best when you take it every day.

What are the ingredients?

Each Capsule contains:

Oval Estrobolome Complex™ – a proprietary blend of three clinically studied probiotic strains (Lactiplantibacillus plantarum KABP051, Levilactobacillus brevis KABP052, and Pediococcus acidilactici KABP021) shown to support natural estrogen recycling and counter the symptoms of estrogen decline

Lactobacillus rhamnosus GG – a well-researched probiotic strain for women's health that reinforces gut-barrier integrity, reduces inflammation, and supports vaginal microbiome balance

Organic Acacia Fiber – a gentle prebiotic that nourishes beneficial gut bacteria and helps maintain microbiome stability

All ingredients are non-GMO, gluten-free, and suitable for daily use.

What makes Oval different?

Most menopause supplements focus on symptom relief using herbs or plant estrogens. Oval is rooted in microbiome science—it helps your body support its own estrogen naturally through the gut–hormone connection. It’s a smarter, more effective, and sustainable way to promote balance from within.

Can I take Oval with another probiotic?

You can, but it’s usually not needed. Oval’s formulation is comprehensive and specifically designed to target both gut and hormonal health at once.
