It just kind of sounds to me like you have found the correct current dosage for yourself - 1 or 2. Maybe try increasing your dosage as time goes on. You may aleady be aware of this, but there is some controversy surrounding taking chlorella if you have amalgams. Not everyone agrees it is bad, but those who do say it will leach mercury from your fillings indefinitely and so you never get truly detoxed. Just something to be aware of.
