Frequently asked questions
What is Green Pasture Fermented Cod Liver Oil?
Green Pasture Fermented Cod Liver Oil is cod liver oil processed through long fermentation — no heating. Naturally contains vitamin A, D and omega 3. Part of the traditional Green Pasture range.
Why traditionally fermented or concentrated without heating?
Fermentation and low-temperature concentration preserve the natural vitamins and bioactive substances. With high heating (as in modern fish oil production), vitamin A and D are partly lost.
Why are the exact vitamin A and D levels not on the label?
Wholefood products have batch-variable levels. Green Pasture states that the vitamins are naturally present but vary — this avoids unproven claims and complies with EU Regulation (EU) 1169/2011.
Can I take Fermented Cod Liver Oil during pregnancy?
Cod liver oil and liver products can provide vitamin A in high doses. During pregnancy: only on the advice of a midwife or doctor.
Does Fermented Cod Liver Oil contain allergens?
See the product label for exact allergens — typically fish (cod or skate) and milk (in butter oil blends).
How do I store this?
In a cool, dry place; for liquid gels: refrigeration recommended after opening. Solidifying at low temperatures is normal.
