The present invention relates to solid compositions comprised primarily of phospholipids (also known commercially as lecithin), or enriched phospholipids, in an amount of at least 20% up to 90% by weight of the total phospholipid composition. More particularly, the present invention relates to solid phospholipid compositions that provide enhanced bioactivity of functional ingredients for the treatment, reduction and/or prevention of diseases such as hypercholesterolemia and atherosclerosis.
