Sunflower: for me, I started taking before I started my jabs. For both manuka and cordyceps, for myself, I take alternate days - in the morning on empty stomach. Cordyceps - I bought from eu Yan sang. Must take with warm water. For manuka, also empty stomach. I take 1 spoonful (abit more than teaspoon, but use plastic spoon . Never on metal spoon) without mixing water. Then a while later, drink a bit warm water.
