Reading a label
A supplement label carries two numbers for each nutrient: the amount, and the recommended daily intake (%RDI). We publish the %RDI for both serving sizes, so you can decide based on your needs.

Featured study
Vitamin C & Iron
Everyone says to take iron with vitamin C. The single-meal effect is real and large. Whether it changes your iron stores is a different question, and the evidence is not what the advice suggests.

New research, when it lands.
We'll email you a new study first, as they become available. No Marketing.
Food, not isolate
There's a difference between a synthetic mineral and a nutrient that's found in food. Somada Studies walks through the research, what is known, and where it's still uncertain.
How we capsulate it
Freeze-drying pulls out the water, not the nutrients. It's how a whole organ becomes a capsule with no heat, no fillers, and nothing synthetic added. A gentle process to retain its natural form.
Tools
Use the numbers yourself.
Interactive tools built from the same sources the studies cite — so you can work with the data, not just read about it.
