THE TEACHING CONNECTION

Ask which CoQ10 was tried

Ask which CoQ10 was tried

Dr. Purser’s mitochondrial chapter connects CoQ10 with cellular energy and antioxidant support. It specifically asks about ubiquinol versus ubiquinone and the prior product, rather than assuming that “I tried CoQ10” describes one uniform experience.

Putting the pieces together

Energy concerns can involve nutrient intake, absorption, B vitamins, amino acids and antioxidant defenses. CoQ10 is only one part of that picture; fatigue or brain fog does not prove you need it. Bring a list of products you have already tried.

How supplementation is approached

Ask which form was tried—ubiquinone or ubiquinol—and for how long before deciding CoQ10 did not help. Dr. Purser places CoQ10 in mitochondrial and maintenance support when indicated, alongside the larger energy and redox picture. Avoid adding it twice through an energy blend and a separate capsule.

What symptoms can—and cannot—tell you

There is no established dietary deficiency syndrome for this specific botanical or compound. Symptoms are not evidence that you need this supplement.

Food sources

Small amounts occur in meat, fish and nuts; the body also makes CoQ10.

Supplement forms

Ubiquinone and ubiquinol are common forms.

A question to bring to your visit

Which formulation did I use, for how long, and what else changed at the same time?

What to track and reassess

Record the product, actual use, tolerance and a functional goal such as activity endurance. Review anticoagulant use with the prescribing team.

From starting support to follow-up

If you and your clinician start a CMA replenishment plan, you may add one new product at a time, often waiting 3–7 days to see how you feel. A check-in is usually planned near ten weeks during an approximately 100-day period. Follow your written plan for amounts and timing. At follow-up, you may continue, change, or stop each item. This timetable does not automatically end longer-term support.
