Cod Liver Oil (USP, OTC)

Mixed · 6/10, higher is cleaner

How we reached this

Boudreaux's Butt Paste signature active. USP-grade cod liver oil provides vitamin A + D for diaper-area skin. Distinctive fish odor. Mid-rated for the heavy-metal (mercury, dioxin, PCB) supply-chain concern in non-purified fish-oil sources; USP grade carries lower-limit specs but isn't zero.
