What doesn’t a highly bioavailable butyrate do for gut health and your whole body? That’s the real question.

We’ve waited years for this breakthrough—a powerful, L-Lysine Butyrate that sets the gold standard. Sure, it has an interesting smell, but the taste? It's good. And the results? Exceptional. To our knowledge, it’s the most bioavailable butyrate available.

Hi, I’m Phil. At Silver Fern™, we know the transformative impact a great butyrate product can have. That’s why we’ve held off—waiting for the right option. But we didn’t stop there. We went above and beyond to create Postbiotic+, the ultimate gut health and immune support product.

Why? Like you, our families constantly face sicknesses that disrupt gut health. From sinus infections to nasty viruses, setbacks happen—even with great gut health. And antibiotics? They can take years to recover from. So, we designed a product to keep sickness at bay and crush “man cold” misery once and for all.

But we didn’t stop at immunity. Postbiotic+ is loaded with features that make it indispensable year-round:

1) Metabolic health: Helping you get back into those skinny jeans (when the return to style, which you know they will).*
2) Nutrient absorption: Supercharges your body’s ability to absorb and use nutrients.*
3) Ultimate internal coolant: For when your internal engine is overheating.*
4) Filter fixer: Boost internal defenses to allow the good stuff in and keep the bad stuff out.*


Postbiotic+ isn’t just another supplement—it’s a souped-up, all-in-one response for gut, immune, and metabolic health. Once you try it, it’s a year-round must-have.
