The Claim
It is widely believed that DHA supplements are necessary to maintain and improve heart health, reducing the risk of cardiovascular diseases significantly.
Origin
This belief is propagated by health enthusiasts and supplement companies who highlight studies on omega-3 fatty acids' benefits for heart health.
What Science Says
While DHA, as part of omega-3 fatty acids, has been associated with heart health, systematic reviews and meta-analyses show mixed results. Some studies suggest a modest reduction in heart disease risk, but others show minimal effects. A large 2018 meta-analysis concluded that omega-3 supplements, including DHA, have little to no significant impact on cardiovascular disease outcomes in the general population.

Misleading
