Choose a use that fits the oil

Mayo Clinic dietitians describe flaxseed oil as less cooking-friendly because of its lower smoke point and stronger flavor. A dressing or addition to a finished dish is a practical option instead of high-heat frying. Follow storage and use instructions on the bottle, and use a food-grade product. [1]

ALA is not the same nutrient as EPA or DHA

NIH distinguishes the plant omega-3 ALA from EPA and DHA. Conversion is limited, so a gram of flax oil cannot be counted as a gram of fish-oil EPA plus DHA. Read the relevant fatty acid amount rather than comparing bottle or capsule weights. [2]

Match the form to the intended use

Imagine wanting fiber in breakfast. Oil contributes fat, while the seed is a different food with fiber; pouring oil into a meal does not reproduce the whole seed. Likewise, a culinary use is not evidence for a skin treatment, and a cosmetic product should not be assumed edible. [1][3]
