@turquoise-- There are capsule lecithin supplements?! I thought there were only liquid lecithin and lecithin flakes. I'll take the flakes over the liquid any day. The liquid is horrible.
The only other thing I pay attention to with lecithin supplements is the additional ingredients. I was shocked to find out that some contain sugar and starches. So I only get the ones without these additives. Also, I keep my lecithin supplements in the fridge. Since it's a natural oil, it can go bad quickly at room temperature.
