You can take rooibos as it does not contain caffeien like tea and coffee. If your test is at Lancet and it is not on the disallowed list you probably can take citrus - usually grapefruit is excluded in these kind of tests. Try not to drink any sour juices as this may influence the calcium levels. You must please keep me informed of your progress - this is also a learning process for me!
