Fat Liver Oil Use in Convalescence: Evidence Overview

Fat liver oil, most commonly referring to cod liver oil, has a history of use for recovery during convalescence (the period of recovery after illness). Its traditional use is supported by its nutrient content—especially vitamins A and D, and omega-3 fatty acids (EPA and DHA). During the early 20th century, cod liver oil was commonly prescribed to aid recovery and prevent vitamin deficiencies, especially rickets and general debility after illness.

Modern scientific evidence provides moderate support for its role in convalescence, primarily due to its nutritional profile. Omega-3 fatty acids are known to modulate inflammation and support immune function, which may benefit individuals recovering from illness or surgery. Several studies suggest that adequate intake of vitamin D and omega-3s can improve immune response and may reduce the duration or severity of some infections. Vitamin A is also essential for immune health and tissue repair. However, direct clinical trials specifically assessing cod liver oil or other fish liver oils during convalescence are limited.

In summary, the historical use of fat liver oil in convalescence is bolstered by moderate scientific evidence relating to its nutrient content and the general requirements for recovery, but there is a lack of robust, direct clinical studies specifically targeting its efficacy for this condition. Thus, while scientific rationale exists, more targeted research is warranted.
