Where can I buy lecithin from? And how many capsules should I take daily?

You can also purchase it online from iHerb or GNC. http://sg.iherb.com/Lecithin#p=1 http://www.gnc.com.sg/gnc-triple-lecithin-1200-br-100-softgel-capsules.html You will need to refer to the recommended dosage stated on the bottle because different brands may have different composition for each capsule, therefore, different recommendations (usually 1 or 2 capsules daily).
