Ground flaxseeds are best used when you add them to your recipes, such as sprinkling them over your hot or cold breakfast cereal or yogurt or adding them to your favorite muffin recipe. Each tablespoon of ground flaxseed contains around 1.8 grams of plant omega-3s.

Flaxseed oil is great for drizzling over salads or using for cooking. While flaxseed oil contains omega-3s, it does not have fiber and lignans found in the rest of the seed.
