You add the liquid Q10 to the oil your pulling with. The fat of the oil charges the Q10 along with the dwell time in your mouth while you're pulling.
Be careful, though, the effect can be powerful. I would start with however many drops equal about 30 mgs of Q10 and go up from there if desired.
Again, I would routinely take 200 mgs of Q10 by capsule (Jarrow brand) and get a much bigger reaction from the 30 mgs mixed in with the oil. Not only is it much more powerful, but saves a lot of money since Q10 can be expensive, and is directly contacting the gums for 20 minutes.
