An honest look at what's in your bottle
Most supplements lose half their potency before you swallow them.
The moment a tub is opened, the clock starts. Oxygen, moisture and light begin dismantling the active ingredients you paid for, weeks before the expiry on the label.
The decay curve
Pick an ingredient. Move the months.
We modelled the same active ingredient across the formats the industry actually ships in (tubs, sachets, pills and ready-to-drink cans) and compared each one to a gas-flushed, induction-sealed Reblewm pod. Same pantry. Same conditions. Only the packaging changes.

Highly sensitive to oxygen, moisture and heat. The first thing to go in most multivitamins.

Estimated freshness of Vitamin C remaining at month 6.
Reblewm pod

+21 points more active ingredient preserved in the same conditions.
Directional estimate. Modelled from published ingredient stability characteristics, not from batch-level potency testing. See note below.
The Reblewm format
This is why we sealed every dose in its own pod.
Single-serve. Gas-flushed. Induction-sealed. No oxygen, no moisture, no light, until the moment you click it into water. Every dose tastes, dissolves and performs like the day it was made.
A note on the numbers
The curves above are an educational estimate, informed by published stability literature (ICH Q1A(R2), USP <1191>, peer-reviewed ingredient research) but not calibrated to specific manufacturer batches or Certificates of Analysis. They are intended to communicate relative differences between packaging formats, not exact potency loss, expiry dates, or regulatory compliance.
