Safety: Megadoses (>100 grams) of any type of concentrated oil is likely to induce gastrointestinal distress such as nausea and diarrhea due to a laxative effect. Effective doses of flaxseed or flaxseed oil of 30-40 grams per day are unlikely to pose any adverse side effects.

Dosage: Beneficial effects have been observed at daily doses of 30-40 grams (2-4 ounces) of either concentrated flaxseed oil or whole flaxseeds per day. Popular uses include salad dressings and spreads for the oil, while the seeds are often used in baked goods or sprinkled on cereal or other foods.
