Doctors Are Saying YES
“As a holistic nutritionist, I've seen countless gut supplements offer fake promises and deliver 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.”

Meet the Founder
After their first child, Danielle couldn't shake the bloating, the heaviness, the fog. Probiotics and diets did nothing.
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.
Is it safe and clean?
Vegan, non-GMO, gluten-free, third-party tested and made in the USA, with no fillers or fluff. Contains a soy processing derivative (no soy protein). As with any supplement, check with your physician if you're pregnant, nursing or managing a condition.
What if it's not for me?
That's what the guarantee is for. If Gut Balance isn't the right fit, you're covered by our 90-day money-back guarantee, so you can try it with confidence.
