Fish oil boosts health during menopauseFish Oil Supplementation with Resistance Exercise Training Enhances Physical Function and Cardiometabolic Health in Postmenopausal Women.
High relevance to menopause study
We examined the impact of omega 3 fish oil, paired with resistance exercise, on health in postmenopausal women. In our trial, 20 healthy older women took part in either a resistance training program with fish oil or a placebo for eight weeks.
Both groups showed improvements in physical function, but those taking fish oil experienced a notable boost in handgrip strength and lower blood pressure and inflammatory markers.
This suggests that fish oil could enhance muscle function and reduce health risks for women navigating menopause.

Omega-3s reduce menopause-related depressionAntidepressant activity of ω-3 polyunsaturated fatty acids in ovariectomized rats: role of neuroinflammation and microglial polarization.
Moderately relevant neuroinflammation study
We explored how omega-3 polyunsaturated fatty acids (PUFA) affect mood changes associated with menopause in ovariectomized rats. Our study revealed that menopause led to anxiety and depression-like behaviors, driven by increased neuroinflammation in the brain.
However, we found that omega-3 supplementation helped shift the brain's inflammatory response towards a healthier balance. The omega-3s not only assisted in reducing the negative mood symptoms but also promoted protective effects against neuroinflammation.
Overall, while omega-3 fatty acids show promise, more research is needed to fully understand their benefits for menopause-related issues.

Omega-3 fish oil aids menopause healthBaroreflex sensitivity and central hemodynamics after omega-3 polyunsaturated fatty acids supplementation in an animal model of menopause.
Relevant findings from animal study
We examined how omega-3 polyunsaturated fatty acids (n-3 PUFA) could protect against vascular issues linked to menopause using an ovariectomized rat model.
In our study, we found that n-3 PUFA supplementation helped maintain baroreflex sensitivity, which typically declines after ovariectomy.
Additionally, the central arterial pressure profile remained stable in treated rats, showing a potential protective effect against postmenopausal vascular issues. This suggests that omega-3 fish oil may offer therapeutic benefits during menopause.

We explored the relationship between eicosapentaenoic acid (EPA) intake and estradiol levels in women, specifically focusing on its effects during menopause. The study utilized data from the National Health and Nutrition Examination Survey, which included dietary interviews and serum estradiol level measurements.
Our findings highlighted that higher intakes of EPA were associated with increased estradiol levels in both menopausal and non-menopausal women. Importantly, we noted that EPA intake above a certain threshold was linked to these hormonal changes.
This research suggests that incorporating more EPA into the diet could play a role in regulating estradiol levels, which is particularly beneficial for women's reproductive health during and after menopause. Understanding these connections helps emphasize the importance of nutrition in hormone regulation.

We explored the relationship between docosahexaenoic acid (DHA), a type of omega-3 fatty acid, and breast density among postmenopausal women, particularly focusing on those who are obese. Our study aimed to understand how DHA might differentially affect breast density in obese versus nonobese women, using a method called iTRAQ to analyze plasma samples over two years.
During the study, we identified 173 proteins in the plasma samples. Some of these proteins showed different levels of expression based on whether women were obese or lean. Notably, proteins like the vitamin D binding protein and fibronectin were altered, which suggests a connection between DHA intake and reduced inflammation in obese women.
Our findings indicated that there is an inverse relationship between DHA levels and breast density specifically in postmenopausal obese women. This suggests that greater DHA intake could potentially reduce breast density and may decrease breast cancer risk in this demographic. However, it’s important to note that the effect was not observed in nonobese women.
Overall, this research highlights DHA's role in impacting breast health during menopause, particularly for those with obesity. It opens up further discussions on how dietary changes could play a role in cancer prevention strategies for women going through menopause.
