The Science
The Science behind Every Scoop
We're obsessed with clinical dosing, ingredient transparency, and formulas that actually work. No proprietary blends. Every ingredient is chosen based on research.
Explore Ingredients
Clinically Dosed, No Compromises.
Every Nello formula is built around ingredients based on peer-reviewed clinical studies. No micro-dosing, no proprietary blends hiding behind label tricks.
We publish every ingredient and every dose on the label. Full transparency, always.
Third-Party Tested. Every Batch.
Every batch of every Nello product is independently tested for purity, potency, and banned substances before it ships. We use GMP-certified facilities based in the US for all products.
No shortcuts. No exceptions.
The Best Forms, Not the Cheapest.
We source patented, clinically studied forms of our star ingredients: KSM-66 Ashwagandha, SRI-81 Shatavari, GeniusPure Alpha-GPC, Maizinol. These cost more. They are clinically proven. That's the point.
Every supplier is vetted. Every certificate of analysis is verified.
"If it doesn't work, why take it? If it doesn't taste good, nobody will. We made emotional wellness transparent, clinically dosed, and actually enjoyable. No mystery blends. No fairy dusting. Just wellness you can feel."
Quality Assurance
From Raw Material to Your Hands
Every batch goes through a rigorous multi-step testing pipeline before it ships. No exceptions.
GMP Manufacturing
All Nello supplements are made in FDA registered and inspected facilities that are cGMP certified to ensure quality and safety.
Raw Material Testing
Ingredients are quarantined and released only after they are verified to pass identity, purity, and potency expectations.
Production Testing
Every product undergoes checks for defects at specific time intervals during the manufacturing process to make sure it meets our standards.
Third-Party Testing
Before your product ships, it is tested and confirmed by third-party ISO-accredited laboratories. Meaning every Nello supplement that makes its way to your home complies with USP heavy metal limits, has been checked for microbial contaminants, and has the right amount of active ingredients.
