Because dietary supplements are not subject to
the same regulations that pharmaceuticals are, there is concern
among medical professionals that these products may lack purity
or potency.
Heart rate variability and fatty acid content of blood cell membranes: a dose-response study with n−3 fatty acids

Dietary intake of long-chain n23 polyunsaturated
fatty acids (PUFA) may protect against sudden cardiac
death, an event that may be predicted by measurement of heart
rate variability (HRV).
Ultra-Short-Term Heart Rate Variability is Sensitive to Training Effects in Team Sports Players
