Omega-3

Cognition, memory, and focus is the main area connected here, and any felt benefit should be read together with the human evidence base.

The 52.5 score includes research signals from patient or disease contexts. General supplement evidence is not repeated enough, so the C tier remains conservative.

Representative tier calculated from paper evidence that passed the collection audit.

Positive combinations studied

Positive combination findings are separated by how the study compared the groups. This is not a recommendation to combine them.

Positive findings when used together

The combination had a positive result, but the contribution of each ingredient could not be separated.

Key Evidence #1
Public scholarly dataCitation signal: 777
observational

Among statin-treated patients at high cardiovascular risk, the addition of omega-3 CA, compared with corn oil, to usual background therapies resulted in no significant difference in a composite outcome of major adverse cardiovascular events.

Key Evidence #2
Public scholarly dataCitation signal: 575
review

The pooled data suggest that omega-3 PUFA supplementation may decrease liver fat, however, the optimal dose is currently not known.

Key Evidence #3
Public scholarly dataCitation signal: 524
observational

The ongoing VITamin D and OmegA-3 TriaL (VITAL) is a large randomized, double-blind, placebo-controlled, 2×2 factorial trial of vitamin D and marine omega-3 fatty acids in the primary prevention of cancer and CVD among a multi-ethnic population of 20,000 U.S.

All the new sources have potentially important roles to play in increasing the supply of n-3 LC-PUFA so that they are available more widely and in higher concentrations providing more options and opportunities for human consumers to obtain sufficient EPA and D

Erythrocyte membrane EPA+DHA increases during relatively short intervals in response to supplementation at rates related to amount of supplementation, and may be useful to establish appropriate dosage for omega-3 fatty acid supplementation.
