Real Dosing — Milestone 2 prototype

What are you actually paying for your vitamin D3?

Vitamin D has an established FDA Daily Value, so unlike creatine or omega-3, every product's label amount is already directly comparable — IU and mcg are a fixed 40:1 conversion, not a compound-specific one. There's no verifiability gap here. What this page shows instead is a real brand and format premium: identical doses can cost several times more depending on brand and delivery format (gummy vs. softgel vs. capsule).
