"Are lignans a beneficial ingredient when choosing a flaxseed supplement? The oils that contain lignans have soy lecithin or tocopherols listed as an ingredient. Soy is bad in any form, correct?"

In the case of flax seed oil supplementation, none of these extra ingredients are harmful or truly helpful. The pre-omega compounds in the oil work independently of them, and these do the job. The soy component is probably safe because soy lecithin is highly processed. The heavy processing ironically makes it safer because soy's organic, hormone-disrupting phytoestrogens are filtered and destroyed. We never mentioned this in the article because our very predictable vegetarian and vegan readers would have run with it, and exclaimed, "See, even H.W. promotes soy!". They really are that predictable.
