Supplement
CoQ10 Ubiquinol
CoQ10 has solid evidence for supporting heart health and may help with fatigue, though studies specifically in menopausal women are limited. Your body produces less CoQ10 as you age, and the ubiquinol form is better absorbed than standard CoQ10. If you're dealing with fatigue or taking statin medications, this supplement is worth considering alongside getting CoQ10 from food sources.

Overall: Mixed evidence
Randomised controlled trials
Multiple randomized trials show CoQ10 improves heart function and may reduce fatigue in various populations.
Studies consistently link higher CoQ10 levels with better cardiovascular health and energy levels.
Reviews confirm benefits for heart health and modest improvements in fatigue across different conditions.
Menopause-specific trials
No large studies have specifically tested CoQ10 supplementation in menopausal women for menopause-related symptoms.
What we do not know
We don't know the optimal dose for menopausal women specifically, as most studies have been in older adults with heart conditions. The best timing for taking ubiquinol hasn't been established in controlled trials. We lack data on how CoQ10 supplementation affects hormone-related symptoms like hot flashes or sleep disruption. Most fatigue studies were done in people with chronic diseases, not healthy women experiencing menopause-related tiredness.
How it is used
Common dose range
100-300mg daily as ubiquinol form
Notes on dosing
Ubiquinol absorbs significantly better than ubiquinone after age 40. Take with fatty food.
Get it from food first
Food sources are better absorbed than most supplements and come with co-factors that support the same pathways. If you eat two or three of these consistently, you may not need a supplement at all.
Beef heart
113 g
highest natural source
Sardines
85 g
about 2mg per serving
Mackerel
85 g
good omega-3 bonus
Beef liver
85 g
also rich in B vitamins
Pork
85 g
moderate amounts
Chicken
85 g
smaller amounts but accessible
Mediterranean diet
Rich in fish and healthy fats that support CoQ10 absorption and cardiovascular health
Whole foods approach
Emphasizes organ meats and fatty fish that naturally contain CoQ10
What depletes CoQ10 Ubiquinol
Statin medications significantly reduce CoQ10 production. Intense exercise can deplete levels temporarily. Age naturally decreases production after 40. Some blood pressure medications may also reduce CoQ10 levels.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"Your body's CoQ10 production naturally declines after 40, and if you're on statins or struggling with fatigue, supplementation makes sense. Start with food sources like organ meats and fatty fish, but if you choose to supplement, the ubiquinol form gives you the best chance of absorption."
