Supplement
CoQ10 (Ubiquinone)
Some studies suggest CoQ10 may help with energy, heart health, and reducing oxidative stress during menopause, though results are inconsistent across trials. While our natural production declines after 40, supplementation shows modest benefits for fatigue in some women, particularly those taking statins. The ubiquinone form is less expensive and still effective, though ubiquinol may be better absorbed in midlife.

Overall: Mixed evidence
Randomised controlled trials
Randomized trials show modest improvements in energy and heart function, but results vary significantly between studies and populations.
Population studies consistently link higher CoQ10 levels with better cardiovascular health and less fatigue in older adults.
Reviews suggest CoQ10 supplementation improves exercise capacity and reduces oxidative stress markers, though effect sizes are small to moderate.
Menopause-specific trials
Very few studies have specifically examined CoQ10 in menopausal women, making it hard to know how it works during this hormonal transition.
What we do not know
Most CoQ10 studies have been done in men or mixed populations, not specifically menopausal women. We don't know the optimal dose for menopause-related fatigue or how long it takes to see benefits. No studies have compared ubiquinone versus ubiquinol specifically in women over 40. The interaction between declining estrogen and CoQ10 effectiveness hasn't been studied. Long-term safety data beyond two years is limited.
How it is used
Common dose range
100-300mg daily
Notes on dosing
Take with fatty food. If you are over 40 or on statins ubiquinol is the preferred form.
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 but not practical for most
sardines
100 g
provides about 6mg, plus omega-3s
mackerel
100 g
about 4mg with heart-healthy fats
peanuts
28 g
about 0.8mg, easy snack option
Mediterranean diet
Rich in fish, nuts, and olive oil that naturally contain CoQ10 and support its production
Anti-inflammatory eating
Reduces oxidative stress that depletes CoQ10 stores in the body
What depletes CoQ10 (Ubiquinone)
Statin medications significantly reduce CoQ10 production. Aging naturally decreases synthesis. High sugar intake and processed foods increase oxidative stress that depletes CoQ10. Beta-blockers may also lower levels.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"CoQ10 won't transform your energy overnight, but it might give you a gentle boost, especially if you're dealing with statin-related fatigue or want to support your heart health through this transition. Start with 100mg of ubiquinone with a fat-containing meal and give it 8-12 weeks to see if you notice a difference."
