Surviving the stomach acid is only the first step - MAKTrek® is our proprietary seaweed delivery matrix that releases probiotics gradually over 6-7 hours - engineered to distribute live beneficial bacteria to your entire microbiome

  • 42 Years

    Over four decades of probiotic manufacturing experience back every capsule and formula we engineer.

  • 3rd Party Lab Tested

    Every batch independently verified for potency, purity, and what's actually inside the capsule.

  • 80% Survivability

    Conventional probiotics can survive stomach acid at rates as low as 5-10%. Ours is independently verified at 80%, tested on our patent-pending GI Simulator - we call her Samantha.

  • AFU Tested

    We measure what's alive and active, not just what grows on a lab plate.

No other probiotic does this.

Bloating and irregularity often start with an imbalanced gut.
Most probiotics face two fates: killed off by stomach acid, or released all at once in one spot once the capsule bursts.

Meet the blob — our seaweed matrix, MAKTrek®. Designed to slowly dissolve over 6-7 hours, forming a protective barrier that carries live bacteria across your entire digestive tract, not just one stop.

Your gut and brain are in constant conversation, communicating through what scientists call the gut-brain axis. Lactobacillus plantarum, the leading strain in our Gut-Brain Support blend, has been studied in human clinical trials for its role in stress response and cognitive function.

Did you know? Most of your immune system lives in your gut. Lactobacillus rhamnosus GG, included in our Immune Support blend, is one of the most extensively studied probiotic strains in the world, with clinical research spanning immune response and respiratory health.

Your gut microbiome is sometimes called your "second brain". it doesn't just aid digestion, it plays a role in immune defense, metabolism, and communication with your brain and nervous system.

Research increasingly links a balanced gut to overall well-being, not just how you feel after a meal. We built NSTINCT around that whole picture: a healthier gut, supporting a healthier you.

Where lifestyle meets science.

and you meet the version of you that finally feels lighter, happier and healthier.

The probiotic industry is mostly marketing - making it extremely confusing to understand what matters and why.

That's what we've broken down for you below.

When looking for what makes a probiotic worth your hard-earned money, these five sections will give you everything you need to know to make the right investment into your health.

Delivery & Survival

Targeted Delayed Release Delivery

MAKTrek® Seaweed Matrix

Slowly dissolved over 6-7 hours

  • Protecting against both stomach acid and bile, forming a secondary barrier around the probiotics for the entirety of digestion. This ensures probiotic delivery across your entire GI tract.

Biodiversity

30 Strains Specifically Chosen Based on Clinical Trials

We named our probiotic blend Rainforest - with 30 strains designed with 40+ years experience in manufacturing probiotics - these strains and species have been hand picked for their specific benefits for immune support, migrobiome support and GUT-Brain Support.

Prebiotics

Prebiotics Are Essential to Feed Your Healthy Bacteria

Prebiotics are basically food for the probiotics.

That’s why we chose 3 prebiotic fibers that all work a little differently to support the live bacteria - Acacia gum, Arabinogalactan & Inulin. All 3 of these occur naturally and come together to create a broad-spectrum blend.

Postbiotics*

Proprietary Blend Specifically Designed for Function

Postbiotics are the waste your probiotics produce and are actually where most of the benefit comes from by taking probiotics.

MAKTabolite® is designed to complement complex custom blends, giving our formulation added depth and functionality.

*Postbiotics may be labeled as: Secondary metabolites, dead cultures, or cultured fermentate

There is what is known as “pixie-dusting” in the industry. It is adding just enough of one strain to put it on the label but provides no real benefit. This is why we list each strain & it’s activity level on our site. We get these numbers from sending blind samples to 3rd party testing so there is no bias in the resulting activity number.
