In a follow-up period of nine years, the researchers concluded that fish oil supplementation caused:
- 388 fewer all-cause deaths
- 124 fewer cardiovascular disease deaths
- 95 fewer cardiovascular events per 100,000 people.
The researchers added: “The association between fish oil use and CVD events appeared to be stronger among those with high blood pressure.
“These favourable associations remained after taking account of traditional risk factors, such as age, sex, lifestyle habits, diet, medication and other supplement use.”
While there may have been a large sample size, this is an observational study.
