I used one a day of Puritan's Pride Q-Sorb 400mg form for 6 months for my migraine. I didn't see any effect so I discontinued.
It is widely discussed that Q-gel form or Ubiquinol form is more potent but it lacks information, if this active form is REALLY absorbed. I am in my mid-30s and I believe I do not have any enzyme insufficiency that will not convert CoQ10 to Ubiquinol in the body.

(P.S. - Since I am new to this forum, I am not allowed to link anything so sorry can't offer link)
