ZebraThrive exists because the EDS, POTS, and MCAS triad needs a formulation built around its constraints from the start - not a generic multivitamin retrofitted with a few flagship ingredients. This page is our constitution: a formal, public commitment to how we do that work.
Our constitution is short and specific. Every clinical claim on this site is anchored to peer-reviewed published research. Mechanism citations include in vitro and animal studies where those are the best available evidence; clinical-outcome and dose claims come from human trials wherever those exist. Each ingredient page lists the PMID, authors, study design, and finding so you can evaluate the strength of the evidence yourself, not just trust our framing. If we can't cite it, we don't claim it.
Every excipient is disclosed and chosen with MCAS in mind: HPMC capsules (no gelatin, no carrageenan), a calcium carbonate opacifier on the PM caps (no titanium dioxide), and rice hull concentrate and L-leucine as flow agents (no magnesium stearate). Some vitamins and actives arrive on carriers, and we list those too: maltodextrin on the vitamin D3 (about 17 mg a day), microcrystalline cellulose on the vitamin K2 (about 10 mg), sunflower lecithin in the quercetin phytosome, and silica in the taurine (up to 7.5 mg). We are confirming the last two carriers, in the astaxanthin beadlet and the selenium premix, with our manufacturer and will list them before launch. No FD&C dyes, no citric acid, no soy derivatives, and no fermentation-derived ingredients where a non-fermented form exists. Every batch comes with Certificate of Analysis verification on identity, potency, and contaminants.
We don't claim to treat, cure, or prevent anything. We do claim to give you ingredients with documented mechanisms in research, at doses supported by clinical evidence, in a formulation engineered for the sensitivities of the EDS/POTS/MCAS triad.
We're zebras ourselves, and the existing supplement market wasn't serving us - generic "multivitamins" load up on the wrong forms and the wrong excipients, while specialty MCAS brands lack the ECM-protective and methylation coverage that hEDS and POTS need. So we built what we'd want to take ourselves.
Full transparency. Every ingredient, every source, and every excipient disclosed. No 'proprietary blends.' No secrets.
No titanium dioxide. No mold-derived citric acid. No artificial dyes. No carrageenan. We prioritize biological function over shelf aesthetics.
If a dose isn't at a clinically effective level, it doesn't belong. We refuse to use 'pixie dusting' just to pad our labels.
We research how our ingredients interact with beta-blockers, fludrocortisone, midodrine, and the other medications you actually take.
No miracle claims. No fear tactics. No hype. We provide evidence and honesty, not false hope.
If you report a problem, we believe you first and investigate second. You've been gaslit by the medical industry enough.
Every formulation is grounded in human clinical research. When the science isn't clear, we say so plainly.
Histamine screening. Heavy metals. Biogenic amines. We test for the specific contaminants that trigger your population.
Minimal fillers. Every carrier disclosed. We treat 'inactive' ingredients with the same scrutiny as active ones.
Openable capsules. Powder options. We provide micro-dosing guidance because 'low and slow' is how your body works.
Our system is designed to reduce your pill burden. One trusted solution to replace twenty random bottles.
Your feedback shapes our lab work. Your lived experience matters more to us than any marketing trend.
Full ingredient sourcing is disclosed on every single product we release.
Third-party COAs are available upon request to verify the molecular purity of every batch.
Strict adherence to current Good Manufacturing Practices with rigorous third-party verification.
Public logs documenting exactly why we included or excluded every ingredient in the formula.
"We're not a wellness brand chasing trends. We're a safe harbor for people whose bodies don't follow the rules."
