Association Between Dietary Intake of Omega-3 Fatty Acids and Serum Testosterone in Adult Males: Results From NHANES 2011-2016 and 2021-2023.
Plain-language summary
This study looked at whether eating more omega-3 fatty acids (healthy fats found in fish and some plants) is linked to higher testosterone levels in men. It used data from a large US health survey (NHANES) of men aged 18 and older, analyzing their omega-3 intake and testosterone levels. The study found that one specific omega-3, DPA, was linked to higher testosterone overall, while other omega-3s like ALA and DHA showed positive links only in men with lower or higher body weight. However, the study design cannot prove that omega-3s directly raise testosterone.
Key findings
- DPA (docosapentaenoic acid) was positively linked to serum testosterone.
- Total omega-3 and ALA (alpha linolenic acid) were positively linked to testosterone in men with higher BMI.
- No significant associations were found for DHA, EPA, or SDA.
How to analyze the study yourself
- Study type
- Cross-sectional studies are good for spotting associations but cannot establish cause and effect.
- Population
- Adult males aged 18 and older from the NHANES 2011-2016 and 2021-2023 surveys.
- Funding
- Not reported
- Watch for
- This study found that certain omega-3s, especially DPA, were linked to higher testosterone in men, with stronger links in leaner or heavier men. If you are looking to support your testosterone naturally, it may be worth adding omega-3-rich foods like fatty fish, flaxseed, or walnuts to your diet.
