what it claims

To support heart, brain, and immune system health, it is recommended to use a high-quality omega-3 supplement (with transparent purity testing) to compensate for insufficient intake in the modern diet.

The claim that a large portion of the population lacks omega-3s is validated by observational data (notably the US NHANES surveys), which show that fatty fish consumption is often insufficient to reach optimal levels of vitality. Regarding cardiovascular well-being, a meta-analysis by the Cochrane Collaboration (Abdelhamid et al., 2020) confirms that EPA and DHA intake actively supports heart health, although benefits are optimized when integrated into an overall healthy lifestyle. For brain function, a systematic review (Yurko-Mauro et al., 2015) indicates that DHA supplementation helps preserve cognitive function and memory. As for immune support, analyses of randomized controlled trials (such as those by Miles and Calder, 2012) suggest that these fatty acids positively modulate the response of our protective cells. Finally, the creator's emphasis on verifying the purity and oxidation of batches is scientifically very relevant, as fish oils are sensitive to rancidity.

What the graded evidence says

Effect
cardiovascular mortality / events; atrial fibrillation; mood — EPA monotherapy RR 0.82 (0.68-0.99) for CV mortality vs weak EPA+DHA RR 0.94 (0.89-0.99); AF increased RR 1.26 (1.08-1.48); mood SMD -0.28 (EPA-predominant, dose <=1 g/day)
Measured on
general adults (primary prevention), high-triglyceride statin-treated adults, adults with low mood

What’s uncertain

The heart benefits people expect from everyday fish-oil pills largely didn't show up in big trials. Real benefit is narrow (high-dose EPA, high triglycerides) and high doses carry a small atrial-fibrillation and bleeding trade-off.
