A company called Zenith Advanced Health Systems once
sold a formula that combined
cod liver oil and flaxseed oil, claiming that the X Factor was an unsaturated fatty acid (sometimes called vitamin F) found in flaxseed oil.
A year later I started a business
selling nutrient dense foods, including GPP Blue Ice
Cod Liver Oil (before FCLO had been developed), Celtic Sea Salt and Nature's Blessings Coconut Oil, etc..
