Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Calanus finmarchicus oil is a marine oil derived from a small zooplankton and is increasingly studied for its potential cardiovascular benefits. The primary scientific rationale for its use in supporting heart health is its content of long-chain omega-3 fatty acids (EPA and DHA), as well as wax esters and astaxanthin. Several preclinical and small human studies suggest that Calanus oil may help improve lipid profiles, reduce inflammation, and support metabolic health—factors relevant to heart health and "heart weakness," a non-specific term often referring to reduced cardiac function or heart failure risk.

However, the strength of the evidence is modest. Most clinical trials are small, short-term, or focused on surrogate endpoints such as lipid levels, markers of inflammation, or vascular function, rather than hard cardiovascular outcomes. For example, a 2019 randomized controlled trial showed improvements in some metabolic parameters in overweight individuals, but did not directly assess heart disease or heart failure. While the omega-3 content is established as beneficial for cardiovascular risk in broader research, direct evidence for Calanus oil specifically improving or treating heart weakness in humans is limited. Therefore, while there is a scientific rationale and some preliminary evidence, robust clinical validation is lacking, and the overall evidence rating is 2 out of 5.
