Where I reside overseas the only 2 Ubiquinol products are Eckhart Corp's Vitamode CoQ10, & Tishcon Corp's Stay-well Active Q. I am 67- which is best?

CoQ10 choices. As supplements and vitamins are not uniformly regulated it's difficult to say if one is better than another, as the quality may vary even within the same brand from one "batch" to the next. Pick a brand that you trust or someone can recommend, but still no guarantees.
