CoQ10 (3000mg in a single dose or 4000mg if you weigh more than 155 lbs) is used as a mop up after doing your other parasite treatments. DE could be used along with it, since it works differently from CoQ10, or you could take the DE for a week or more with the Humaworm or after the Humaworm, and then take the CoQ10. The CoQ10 made me fuzzy in my head for a few hours the first time I took it. I took a follow-up dose several days later. The second time I still experienced a little of the fuzziness in my head, but it was MUCH less.
