We started with a simple observation: most people who care deeply about what they eat are still taking supplements full of synthetic isolates and unnecessary fillers. That felt wrong to us.
So we set out to fix it, one nutrient at a time.
Every Holistico formula is built around a single vitamin or mineral, sourced from real foods that naturally contain the cofactors your body expects. No isolating nutrients from their natural context. No artificial fillers. Just food, concentrated and bottled.
Each formula stands alone or stacks with the rest of the line and we're just getting started. The goal is a complete whole-food lineup covering every essential nutrient, built the same way every time.
Just real ingredients with nothing to hide.
We don't cut corners. Every Holistico formula is made with traceable, food-based ingredients and zero synthetic additives. What's on the label is exactly what's in the bottle.
Every product is manufactured at an FDA-registered, cGMP-certified facility in Hauppauge, New York where strict quality control and manufacturing consistency are non-negotiable. Every batch is tested for potency, ingredient identity, microbial safety (including Salmonella, E. coli, and Staph aureus), and heavy metals (Mercury, Lead, Arsenic, and Cadmium) before it ever leaves the facility. Certificates of Analysis are available upon request.
We're also big on transparency. Whole-food sourcing means natural variability. Slight differences in color or texture are normal and expected. That's what real food looks like.
Quality isn't a buzzword for us. It's just how we do things.
Most people choose supplements based on a hunch. We think you deserve better than that.
That's why we offer access to the SpectraCell Micronutrient Test, a functional lab assessment that goes deeper than your standard bloodwork. Instead of just measuring what's circulating in your blood at a single point in time, it evaluates how nutrients are actually being used at the cellular level. Big difference.
The result? A clear picture of where your gaps are, so you can supplement with intention. No more buying products just because some influencer on the internet said so.
Gather the data. Know your gaps. Fill them with real, whole-food nutrition.
This test is not intended to diagnose or treat any medical condition.
Hi, it’s Katie! I’m a Registered Holistic Nutritionist, Functional Diagnostic Nutrition Practitioner, and the person behind Holistico.
My interest in nutrition didn't start in a classroom. It started with my own body. Navigating nutrient imbalances, skin issues, digestive problems, and hormonal challenges pushed me to dig deeper than conventional advice was taking me. Eventually I stopped chasing symptoms and started looking at the full picture; whole foods, functional nutrient testing, lifestyle, root causes.
After years of working with clients, a pattern became impossible to ignore: the people most committed to eating well were still taking heavily processed supplements their bodies couldn't even use or recognize properly. Synthetic isolated forms, imbalanced nutrients, fillers that had no business being there.
That's what led me to build Holistico.
Every formula we make is rooted in the same belief: nutrients work best when they are in their food form. Real ingredients with their natural cofactors. No artificial junk. Just the way nature intended.
