Why Omega-3 Is Important for People Over 40
Omega-3 fatty acids are essential for heart, brain, and joint health. As we age, maintaining optimal levels of omega-3 becomes increasingly important for reducing inflammation, supporting cognitive function, and promoting cardiovascular wellbeing.
Many people over 40 may not get enough omega-3 from their diet alone, making supplementation a practical option. High-quality omega-3 supplements can help bridge this gap, especially for those who don’t regularly consume fatty fish.

Frequently Asked Questions About Omega-3 Supplements
Why should people over 40 take omega-3 supplements?
Omega-3s support heart, brain, and joint health, all of which become more important as we age. Supplementation helps ensure adequate intake, especially if your diet is low in fatty fish.
What is the difference between EPA and DHA?
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the two most important omega-3 fatty acids for human health. EPA is mainly linked to heart health and inflammation, while DHA is crucial for brain and eye function.
Are there plant-based omega-3 supplements?
Yes, plant-based omega-3 supplements (usually from algae oil) are available for vegetarians and vegans. These provide DHA, and sometimes EPA, without the use of fish.
Can omega-3 supplements cause side effects?
Omega-3 supplements are generally safe, but high doses may cause digestive discomfort or interact with blood-thinning medications. Always follow dosage recommendations and consult your healthcare provider if you have concerns.

Omega-3 supplements can play a key role in supporting the health of people over 40, especially for heart, brain, and joint function. Choose a high-quality, third-party tested product for the best results.
