Re: Flax seed oil capsules
Someone will correct me if I'm wrong, but I think you are right that "pure" flaxseed oil does not contain lignan. The "high lignan" flaxseed oil has the lignan added back in after the oil is expelled.
But I think your math is off for the dosage--or my brain is still asleep. Here's Jaini's "make your brain hurt" post on flaxseed and flaxseed oil: https://ecir.groups.io/g/main/message/203051 The most important part for you to know is this sentence: "Horses on pasture eat about 17 grams/day omega 3 (1,000 lb horse)".
1 gram = 1000mgs, so if your capsules contain 500 mg, and you need 17 grams (17000 mgs) my math shows that you need 34 capsules (yikes!) to equal 17 grams of omega 3. I *think* you may have only multiplied the 17 grams by 100 = 1700 divided by 500 = 3.4 capsules, but PLEASE recheck my math!!
