Rating (out of 5): 2

Fish roe (fish eggs) is sometimes discussed in relation to supporting or treating depression due to its rich content of omega-3 fatty acids, particularly EPA and DHA. Scientific studies have shown that omega-3 fatty acids can play a role in brain health and may have some benefit in alleviating symptoms of depression. However, the majority of clinical trials and meta-analyses have focused on purified fish oil supplements rather than fish roe specifically. Fish roe does provide a potent natural source of these fatty acids, as well as other nutrients like vitamin D, B12, and selenium, which are also relevant to neurological function.

There is moderate scientific plausibility for using fish roe as part of an overall dietary approach to mental health, due to its nutrient profile. However, there are no robust clinical trials directly investigating fish roe consumption and depression outcomes. Evidence from studies on omega-3 supplementation suggests a modest effect for some individuals with depression, but results are mixed and not universally conclusive. Thus, while there is a scientific rationale for including fish roe in the diet of individuals seeking to support brain health, its use as a treatment for depression is not directly validated by clinical studies focused on fish roe itself.

In summary, evidence supporting fish roe for depression is extrapolated from broader research on omega-3s, and the strength of direct evidence is limited.
