An invitation into a world where Cistus – a powerful Mediterranean plant – blends with Grapefruit oil and Postbiotics to create a ritual that protects, soothes, and refreshes without disrupting your natural balance.
Oral wellbeing - Bioactive. Microbiome-friendly. Beautifully bitter. Beautifully sweet. Beautifully different.
Andrea Sokol, Gesundheitsexpertin, @Ohlala & Solala
Bitter Sweet began with a shared vision between Natch and Andrea Sokol:
to create a mouthwash that supports overall wellbeing, honours the body’s natural abilities, and stays rooted in nature.
A formula that channels nature’s quiet strength into daily oral comfort.
This one-of-a-kind mouthwash tab emerged from a deep creative collaboration with Andrea Sokol – author, health advocate and founder of Ohlala & Solala – who inspired us to value the extraordinary properties of Cistus, the Mediterranean “super-plant”.
What once seemed impossible became reality: transforming the intense, herbaceous character of Cistus into a microbiome-friendly, modern and refreshing mouthwash experience.
We experimented, refined, tasted, adjusted – until we found the perfect bittersweet harmony between Cistus, Grapefruit and Postbiotics.
The result is a one of a kind innovation:
a chewable, bioactive mouthwash tab that unites botanical tradition with modern microbiome science.
A formula created with intention.
Crafted with courage.
And designed to support your oral wellbeing in an entirely new way.

Powered by Cistus. Crafted for natural microbiome balance.
Cistus – one of the Mediterranean’s most remarkable botanicals – sits at the heart of this formula.
Known for its natural astringency and polyphenol richness – traditionally valued in oral care – Cistus brings a sense of purity, wholeness and soothing care to your daily ritual.
Blended with Grapefruit oils and Postbiotics, Bitter Sweet becomes an entirely new kind of mouthwash: bioactive, balancing, and beautifully bittersweet.
To understand how to support a well-balanced oral environment, it helps to know three key players:
Postbiotics are valued in oral care for their stability and their role in supporting a well-cared-for oral environment. As fermentation-derived bioactive substances, they help create conditions that are more favorable for beneficial bacteria — contributing to a healthy oral ecosystem.
Postbiotics can help:
This is the foundation of our formula — postbiotic technology working daily to support the conditions your oral microflora needs to thrive.
Mediterranean botanical oil with warm, herbaceous notes, traditionally valued for its rich antioxidant profile. Promotes oral comfort while leaving the mouth feeling soothed, balanced and refreshed.
Naturally rich in vitamin C and antioxidants, delivers zesty citrus notes with cleansing and astringent properties for long-lasting freshness.
A biomimetic mineral that helps remineralizes tooth enamel by filling microscopic surface cracks, helping to smooth and restore for a naturally polished feel.
A natural, low-calorie sugar substitute that stimulates protective saliva flow while disrupting cavity-causing bacteria's metabolic processes. Prevents acid production, reduces bacterial adhesion, and supports optimal pH balance and enamel remineralization.
A plant-based fibre that helps soothe oral tissues and forms a gentle protective film to support comfortable, everyday mouth feel.
Helps with plaque control and improves oral hygiene by reducing odor-causing bacteria.
