All my family members are taking lecithin continuously for over a year. Adults - 2 capsules 2 times a day with food. Children - 1 capsule 1 or 2 times per day. We tried lecithin different manufacturers, including Now Foods and Source Natural. But the lecithin from Natural Factors believe is the best. Capsules him darker than the other manufacturers and a little smoother, ie, less "big-bellied" - children swallow it easier. The main advantage of this particular lecithin compared with other believe that it is unbleached, ie, not discolored, and therefore, more natural and natural. I put 5 stars is not only the lecithin, but in general the manufacturer Natural Factors - he is trustworthy in many ways. We buy Omega 3, coenzyme Q10 is this manufacturer.
