This January, Dr. Linda Linday, a pediatrician who researches cod liver oil, Michael F. Holick, MD PhD, and several other researchers defended cod liver oil against criticism made a year earlier by Dr. Cannell of the Vitamin D Council and 16 other researchers.
They cite the WAPF December 2008 “Cod Liver Oil Update” as an example of the importance of the vitamin A-to-D ratio emerging in the online supplement and nutrition newsletter communities. This update was based largely on the work I have done for WAPF on the fat-soluble vtamins. They suggest the optimal ratio is between four and eight, in IUs.
