Omega-3 fatty acids — specifically EPA and DHA — are among the most well-researched nutrients in modern medicine. They play a fundamental role in cardiovascular health, cognitive function, joint mobility, and systemic inflammation control. Yet the average Western diet provides only a fraction of the recommended intake, making supplementation a practical necessity for most people.
Why Omega-3 Matters
The modern diet is heavily skewed toward omega-6 fatty acids (from vegetable oils, processed foods, and grain-fed meat) relative to omega-3s. This imbalance — often exceeding a 15:1 ratio when the ideal is closer to 2:1 — promotes chronic low-grade inflammation, which is a root driver of heart disease, diabetes, neurodegeneration, and metabolic syndrome.
What to Look For in a Fish Oil
Not all fish oil supplements are equal. The key differentiators are EPA+DHA concentration per serving (aim for 1000mg+ combined), molecular form (triglyceride form absorbs 70% better than ethyl ester), purity testing for heavy metals and PCBs, and freshness indicators (TOTOX value under 26).

Storage Tips
Fish oil is sensitive to heat, light, and oxygen. Store supplements in a cool, dark place or refrigerate after opening. If capsules develop a strong fishy smell, they may have oxidized and should be discarded. Check the expiration date before purchasing and choose products with recent manufacture dates.
