The gut bioactive that does what probiotics can't

Dr. Stuart Weinberger
MD, Gastroenterologist
Postbiotics are the most direct support your gut can get
Debloat & Comfort
End the bloating and that heavy, pressured feeling after meals.
Regularity
Regular, predictable bathroom trips, so you're not planning your morning around them.
Energy & Clarity
Steadier energy and a clearer head, the payoff of a calmer gut.
Immune Support
Everyday defenses, supported where most of your immunity lives: the gut.
Why Postbiotics?
Because probiotics have to survive.
Postbiotics are ready to work.
Skip the fragile bacteria.
Most probiotics don't survive digestion.
The few that do create Postbiotics – the beneficial compounds your body actually uses.
SecondKind delivers Postbiotics directly to support a lighter gut, clearer mind, and more balanced you - fast.*
No fragile live bacteria. Just results.
Beyond Pre or Probiotics.
Clinically Studied Postbiotics
Every active in BiomeBalance™ is backed by its own published clinical research.
Doctors Are Saying YES
"By centering its formulas around postbiotics, SecondKind is translating the latest gut-brain research into something accessible for consumers. It reflects a more modern, science-forward understanding of digestive health."
"As a holistic nutritionist, I’ve seen countless gut supplements offer fake promises and deliver nothing…. ineffective results. SecondKind stands apart because it’s postbiotic-first - finally, a solution that aligns with what the science tells us the body truly needs."
"Gut health isn’t a niche topic anymore - it’s whole-body health, rooted in neuroscience and immunology. In clinical research, postbiotics are emerging as a direct, bioavailable way to influence gut health and systemic balance."
"Why wait for your gut bacteria to do all the work? Postbiotics skip the middleman - supporting a happier gut, stronger immunity, and better wellness from the inside out."
"Bereum, used in SecondKind’s Gut Balance and Mood Balance, promotes the production of SCFAs to optimize microbiome balance. This fundamental support strengthens physical health and helps manage stress, offering results you can actually feel. It's why I recommend SecondKind."
4.8★ for less bloat and regular mornings
"I'd tried probiotics and honestly didn't notice much. A couple of weeks on the postbiotics and the bloating and gas are gone. Everything feels steady and regular."
"I struggled with bloating for as long as I can remember and my doctors mostly said it was probably hormonal. After a few weeks I feel so much better. I'm no longer constantly bloated."
"On my third bottle and the difference is real. The bloating's gone, and my mornings are regular again instead of a guessing game."

So Remy built the targeted postbiotics that finally gave her back to herself. That formula became SecondKind.
Frequently Asked Questions
Probiotics didn't work for me. Why would this?
You're not alone, and it's not on you. Probiotics are fragile and slow, and many never survive digestion. Postbiotics are the ready-to-use compounds those bacteria were supposed to make, delivered directly. Nothing has to survive or colonize first, so the impact is often felt faster.
How fast will I notice something? (week by week)
Many feel lighter and less bloated within the first week, some within days. Around week 2, digestion feels more predictable. By weeks 3 to 4, the difference is clearer and energy steadier. By month 2 to 3, comfort becomes your baseline. Most who respond notice meaningful change within the first bottle, building with daily use.
What are postbiotics, exactly?
The active compounds created by good gut bacteria, the part your body actually uses. They don't need to survive stomach acid or colonize your gut, so they're ready to support gut comfort, regularity and whole-body balance from day one.
How do I take it?
Two capsules a day, one in the morning and one at night, with or without food. Each bottle is a 30-day supply. No refrigeration needed.
