What is an RCT and why does it matter?

A Randomized Controlled Trial randomly assigns participants to either the active ingredient or a placebo. It is the gold standard in nutrition science because it removes bias and isolates the effect of the supplement itself. Every Nutriva claim is backed by at least one published RCT.

Why are proprietary blends a problem?

Proprietary blends hide the individual dose of each ingredient behind a single total weight. That makes it impossible to verify whether you are getting the clinically effective dose. Nutriva discloses every single dose — always.

What does NSF Certified for Sport mean?

NSF Certified for Sport is the most stringent third-party certification in the supplement industry. It tests every batch for over 280 banned substances, contaminants, and label accuracy. It is the standard used by professional athletes worldwide.

How does Nutriva update formulations when new research is published?

Our Scientific Advisory Board reviews newly published research every quarter. If a stronger form, better dose, or superior synergy is identified, we revise the formulation and publicly document the change in our annual Formulation Report.

Our Methodology

How we develop our formulas.

Every Nutriva formulation goes through a 5-stage scientific process — before it ever enters production.

01
Systematic literature review
At least 15 peer-reviewed studies evaluated per ingredient. Only ingredients with ≥3 positive RCTs make the longlist.
02
Dosage validation
Every dose matches the effective amount used in published studies — not the cheapest amount. No ingredient is allowed below the clinically supported threshold.
03
Interaction screening
All ingredient combinations are screened for synergies and antagonisms. Our Scientific Advisory Board (3 university professors) signs off.
04
Independent lab verification
Every batch is tested by Eurofins and Intertek: purity, dose accuracy, contaminant-free. Results published.
05
Post-market surveillance
Customer outcome tracking (opt-in) and yearly formulation reviews. If new studies prove a better form — we update.
