Omega-3 fatty acids — particularly EPA and DHA — are among the most studied and most beneficial nutrients in the human diet. For keto dieters who eat fatty fish regularly, food sources may be sufficient. For others, supplementation is valuable.
The most widely available and affordable omega-3 supplement. Contains EPA and DHA directly. Choose products with high EPA/DHA content per capsule, third-party tested for oxidation and mercury. Take with a fatty meal for best absorption.
Krill oil contains EPA and DHA in phospholipid form, which may offer superior absorption. It also contains astaxanthin — a potent antioxidant. More expensive than fish oil but smaller doses may be effective.
The plant-based omega-3 option and the only direct source of DHA without animal products. Ideal for vegetarians and vegans on keto. DHA content is excellent; EPA content varies by product.
Target 1–3g combined EPA+DHA daily. Higher doses (2–4g EPA specifically) are used therapeutically for inflammation and cardiovascular protection.
Fatty fish 2–3× per week provides meaningful omega-3s. Our keto main dish recipes and keto lunch ideas feature salmon, mackerel, and sardines regularly.
