Abstract The effect of sea buckthorn seed oil (SSO) on exercise‐induced fatigue in mice was explored. The animals were randomly divided into a normal control group, exercise‐induced fatigue group (EFG), SSO low‐dose group, SSO medium‐dose group, and SSO high‐dose group. The mice in all the groups underwent swimming training for 10 days. Those in the treatment groups received different amounts of SSO (0.85, 1.68, and 3.35 g/kg BW [body weight]) before the exercise. All the animals were sacrificed on the last day after an exhaustive swimming test, and serum, liver, and brain specimens were collected. In the exhaustive swimming test, the swimming durations in the SSO‐treated animals were longer than those in the EFG. Furthermore, SSO reduced serum lactic acid, blood urea nitrogen, and hepatic malondialdehyde levels and increased liver glycogen level, hepatic superoxide dismutase level, hypothalamic dopamine content, and glutathione peroxidase level. The SSO treatment decreased hypothalamic 5‐hydroxytryptamine content, lipid hydroperoxide level, NLRP3 inflammasome, and interleukin‐1β protein expression in the prefrontal cortex. Furthermore, it promoted the protein expression of nuclear factor erythroid 2–related factor 2 in the liver. SSO exhibited an excellent antifatigue effect, which may be related to its inhibition of oxidative and inflammatory injury and regulation of hypothalamic neurotransmitters. Practical Application In the present study, the effect of sea buckthorn seed oil on fatigue in mice and its potential mechanism were explored. Taken together, the findings provide insight into the potential role of sea buckthorn seed oil in the development of antifatigue drugs.
