ROOTED IN FERMENTATION SCIENCE.

01 / 04

It starts with kimchi.

Our story begins with fermentation science and the microbial cultures found in kimchi. A familiar food, a fascinating starting point.

02 / 04

Meet the culture at the center.

Lactobacillus plantarum is central to our formula concept. We consider live cultures and heat-treated bacterial components separately, with evidence specific to each preparation.

03 / 04

A thoughtful capsule concept.

From culture selection to formulation, the details matter. Final ingredients, capsule materials and serving directions will be shared when confirmed.

04 / 04

Bring it into your everyday.

Small habits make better days. Discover a daily routine we can build together, one day at a time.

THE FORMULA, OPENLY

A hero culture.
A thoughtful supporting cast.

Live probiotics and a heat-treated bacterial component, each with a distinct role in our formulation concept.

THE HERO

Lactobacillus plantarum

Our starting point is the science of kimchi fermentation. L. plantarum sits at the heart of the Synfi21 formula concept.

LIVE CULTURES / NON-LIVE COMPONENT

The new packaging concept presents kimchi probiotics plus four additional probiotic strains and kimchi-derived heat-killed lactic acid bacteria. Rhamnosus and paracasei remain candidates for the supporting blend. Final strain identities, amounts and claims will be shared after confirmation. Species names alone do not establish a product’s benefits.

PHARMACIST-FOUNDED

Good questions.
Better foundations.

Behind Synfi21 is a pharmacist who believes the details deserve your attention.

Which culture? What form? What do we know—and what still needs to be confirmed? Our founder’s pharmacy background shapes the questions we ask as we develop Synfi21.

01 / Ingredients with context
Clear names and a clear distinction between live and heat-treated bacteria.

02 / Transparency from the start
We’ll share the finished formula and directions when they are ready.

03 / A routine we build together
Support for showing up, one small habit at a time.

A few good questions.

Is Synfi21 available now?

Not yet. Join the launch list for availability and the confirmed formula, serving directions and pricing.

What does kimchi-inspired mean?

Our concept starts with fermentation science, inspired by kimchi and its microbial cultures. Documentation for the selected strains’ origins will be shared once the formula is finalized. This is not a serving of kimchi.

Are heat-treated bacteria the same as probiotics?

No. Probiotics are live microorganisms. Heat-treated bacteria are non-live; evidence for a particular preparation is needed before making specific health claims.

Does registration guarantee a free bottle?

No. The planned 30-day event will have its own eligibility and completion requirements. Registering here requests announcements only.
