“AB INTRA” means “from within” in Latin, and that’s where health truly begins. When your gut is in balance, everything else flows more smoothly: energy, mood, skin, sleep. When your gut thrives, so do you.
Our products are a reflection of what we stand for. We work only with ingredients we trust and partners who share our respect for science, quality and integrity.
We’re not here to chase trends. We’re here to offer formulations that make a difference: thoughtfully designed, precisely dosed and genuinely effective.
No noise, no gimmicks. Just science that works, and integrity that lasts.
My fascination with gut health began during my university years. A lecture on the link between dietary fiber and colon cancer was a turning point for me. I realized my own diet needed a serious change. Adding more fruits, vegetables, and fiber didn’t just improve my digestion, it transformed my energy, skin, and sense of wellbeing.
As I studied molecular nutrition further, I became deeply aware of the mismatch between our biology and the way we live today. Our genes haven’t changed much in thousands of years, but our lifestyle and diet have shifted dramatically, especially in recent centuries. One major consequence is gut dysbiosis: a microbial imbalance that often goes unnoticed, yet affects so much.
Our gut microbiome is like a rainforest: diverse, interdependent, and resilient when properly nourished. But when it’s deprived of fiber and overwhelmed by ultra-processed foods, essential microbial species are starved and gradually vanish. The ecosystem weakens, and its natural functions start to break down. This is what dysbiosis looks like. It’s not just about lost diversity, it’s a system under strain, one that can no longer do its job the way it’s meant to.
At AB INTRA, we make gut care simple, effective, and grounded in science. Our blends bring together ingredients that are often sold separately at higher cost and in suboptimal doses. We formulate with purpose: effective doses, clean ingredients, and combinations backed by science.
If you’re reading this, thank you. Thank you for your curiosity, your trust, or for simply taking an interest in your gut health. Through AB INTRA, I hope to share what I’ve learned: that when you take care of your gut, it takes care of you.

Advanced daily gut health supplement combining prebiotics galacto-oligosaccharides and 2′-fucosyllactose, probiotics Bifidobacterium longum BB536, and L-Glutamine for microbiome balance and gut integrity.
Taking care of your gut shouldn’t be complicated. CORE is my daily essential, a complete blend of prebiotics, probiotics, and L-Glutamine in one simple serving.
I’ve noticed better regularity, steadier energy, and more restful sleep. For me, CORE is more than a supplement, it’s a small daily ritual step that helps me feel grounded and well. It’s also the reason we named it CORE: because a healthy gut really is at the center of it all.
We are guided by scientific integrity. Our formulas are grounded in research and built with intention. We combine the best ingredients with science’s backing to create supplements that deliver real results. They work for a reason: the science stands behind them.
As a family-owned company with no external investors, we have the freedom to create what we truly believe in. We don’t follow trends, we follow scientific evidence. Our focus is simple: products that make a meaningful difference in your health.
