I’m 65, and if I’m honest, staying mentally sharp matters more to me now than it did at 35. One of the supplements I credit for that is Liposomal CoQ10 Ubiquinol 600mg, 60 mini softgels, which I’ve been taking every evening for about a year now.
What CoQ10 actually is, and why ubiquinol specifically
CoQ10 (coenzyme Q10) is a compound your cells use to produce energy — it’s central to how mitochondria, the “power plants” inside your cells, actually function. The catch is that your body’s natural CoQ10 production declines with age, and it’s also depleted by statin medications (which can reduce it by up to 40%, since statins block a pathway your body shares between making cholesterol and making CoQ10).
CoQ10 supplements come in two forms: ubiquinone, the oxidised form your body has to convert before it can use it, and ubiquinol, the already-active, reduced form. Ubiquinol is generally considered the better choice for older adults specifically, because the body’s ability to do that conversion itself also declines with age — so you’re not relying on a process that’s naturally slowing down.
Where the evidence is genuinely strong, and where it’s more modest
I think it’s worth being clear-eyed about this. The strongest evidence for CoQ10 is in heart failure patients — studies have shown real improvements in exercise tolerance, fatigue, and quality of life, and one well-known trial found a meaningful reduction in major cardiovascular events. Statin users experiencing muscle-related side effects are the second group with reasonably good evidence, though results there vary person to person.
For healthy adults over 50 without a specific heart condition, the evidence is more modest — think enhanced exercise performance, reduced fatigue, and better vascular function rather than dramatic outcomes. I mention this because I think it’s more honest than implying CoQ10 will transform anyone’s health, when the reality is it’s a genuinely useful, well-tolerated supplement with age-related and cardiovascular relevance rather than a miracle pill.
A quick honest note on dose
Most of the clinical research on ubiquinol uses doses in the 100–300mg range. This product is 600mg, which is on the higher end — the liposomal delivery format is designed to improve absorption significantly compared to standard softgels, so it’s not a direct like-for-like comparison, but it’s still worth knowing this is a higher-strength product rather than a standard-dose one, and starting there with awareness rather than assuming “more is automatically better.”
What I’ve actually noticed
For me, the standout effect has been mental alertness — and that matters more to me the older I get. I can’t run a controlled experiment on my own brain, but a year of consistent use has coincided with feeling sharper than I’d expect at 65, and CoQ10’s role in cellular energy production (including in the brain, which is a very energy-hungry organ) is a plausible mechanism for that.
How I take it
One softgel a day, in the evening, after food. Taking it with a meal that contains some fat helps with absorption, since CoQ10 is fat-soluble.
A quick safety note
CoQ10 is generally well tolerated, with side effects (when they occur) usually mild — nausea, headache, or occasional insomnia. It can interact with blood thinners and some blood pressure medications, so it’s worth checking with your doctor if you’re on either.
Should you try it?
If you’re over 50, especially if you’re on a statin or have any heart-related concerns, CoQ10 (specifically ubiquinol) is one of the better-evidenced supplements you can add. Even without a specific condition, I think it’s a reasonable addition for supporting energy and mental sharpness as you get older — just go in with realistic expectations rather than anti-ageing marketing hype.
