Thanks for all your replies,
I noticed the protocol that suggests using 5 capsules 3 times a day is for Candida Force, which has the same 10-Undeconoic Acid but the dosage in each capsule may be different,
Here is the label for Candida Force which says it contains only 50mg of 10-Undeconoic Acid per capsule: http://www.candidaplan.com/store/Candida-Force.html
Where as SF722 contains 250mg !

So unless if the labels are incorrect, it makes sense that only 2 capsules of SF722 is plenty compared to 5 of Candida force!
