CoQ10 Benefits for Women Over 50: The ‘Youth Molecule’ That Boosts Weight Loss and Smooths Skin

If your energy, skin and health aren’t glowing quite like they used to, we’re right there with you. So it really got our attention when people started calling the nutrient called CoQ10 a “youth molecule” and “the supplement that every woman over 50 should be taking.” But what exactly is the stuff? And does it live up to the hype? (Spoiler alert: It kinda does!) Keep reading for everything you need to know about CoQ10 benefits for women.

What is CoQ10 exactly?

“Coenzyme Q10—or CoQ10 for short—is a substance our bodies naturally produce using the same enzymes that make cholesterol,” explains Devon Golem, PhD, RD, LDN, founder of NuancedNutritionist.com. “It’s both a powerful antioxidant and a key player in energy production, found basically everywhere we need energy, especially in hardworking organs like the heart, liver and kidneys.”

Signs you may benefit from CoQ10, the ‘youth molecule’

When we’re young, we don’t need to think much about CoQ10. But levels naturally decline with age. And if we end up on statins to lower cholesterol, “these medications dramatically deplete CoQ10,” notes integrative physician and From Fatigued to Fantastic author Jacob Teitelbaum, MD. (Here’s why CoQ10 may ease muscle pain caused by statins.)

Low levels can leave us feeling tired, weak, foggy and like we’re aging at warp speed. Getting more CoQ10 from food (like organ meat and fatty fish) or a dietary supplement (a typical dose is 100 mg) can make it feel a bit like we’re aging in reverse, says Dr. Teitelbaum. “I personally take it myself even though I am quite healthy, because I like the improvement in health and energy,” he says. “CoQ10, along with a good multivitamin, can be a powerful tool for optimizing health and staying young.”

5 exciting CoQ10 health benefits for women

We’ve rounded up highlights of what scientists have discovered so far about the perks of increasing your levels of CoQ10.

It can make energy soar

Golem says CoQ10 “plays a starring role” in the assembly line our bodies use to make energy and deliver it throughout the body. “Without adequate CoQ10, we feel fatigue and sluggishness,” she says. A 2022 Frontiers in Nutrition analysis of over a dozen studies concluded that “CoQ10 is an effective and safe supplement for reducing fatigue symptoms.”

Golem says that in her practice, “some women report noticeable improvements in energy levels and reduced fatigue within four to eight weeks of consistent supplementation.” While others don’t notice dramatic changes, it tends to work best for older adults and people with chronic conditions like heart disease, diabetes and cancer.

It boosts heart health

“CoQ10 is extraordinary for protecting the heart,” says Dr. Teitelbaum. “It prevents cholesterol from damaging the blood vessels. And CoQ10 dramatically improves heart muscle functioning, reversing many heart problems.”

Adds Golem: “Research supports the use of CoQ10 supplementation in individuals with heart failure, especially after a cardiac event. In fact, there’s compelling evidence from the landmark Q-SYMBIO trial that CoQ10 supplementation reduces the risk of future cardiac events, hospitalizations and cardiovascular mortality among congestive heart failure patients. This was a game-changing double-blind, randomized trial that showed real clinical benefits.”

It protects against wrinkles

One of the unique benefits of CoQ10 is that “it can penetrate skin cells and act as an antioxidant shield,” says Golem. “And since CoQ10 is involved in energy production at the cellular level, it may also support the skin’s natural repair processes, which can improve skin texture.” Some research, including a 2024 study in the Journal of Clinical and Aesthetic Dermatology, “suggests it may help reduce the appearance of fine lines and improve skin smoothness.”

This particular benefit is real for former CNBC Reporter Michele Treacy. She says her cardiologist recommended CoQ10 when she was prescribed statins. “I started taking it immediately,” she shares. “I do notice improvements in my skin—and my hair too.”

It may help with weight loss

If your waistband is snug, you may benefit from supplementing with CoQ10. “Without coenzyme Q10, our body’s energy furnaces cannot burn calories for energy. Instead, the calories must be stored as fat,” notes Dr. Teitelbaum. While some research shows little or no impact on weight, a 2024 study in Obesities found that women with metabolic syndrome given CoQ10 experienced significant belly fat reductions.

It protects our brains

“Emerging research suggests CoQ10 may support brain health and potentially slow cognitive decline,” says Golem. This makes sense, she says, since “the brain is an energy-hungry organ!”

How to maximize the benefits of CoQ10 supplements

Choose a supplement verified by a third-party testing organization, such as “NSF International, USP or ConsumerLab,” suggests Golem. “This ensures what’s on the label is actually in the bottle.” She adds that CoQ10 is fat-soluble, so taking it with a meal containing healthy fats improves absorption.

Meanwhile, Dr. Teitelbaum is affiliated with one specific supplement he swears by, finding people seem to absorb it best. “The only CoQ10 I recommend in my practice is the Terry Naturally CoQ10 Chewable. I find 100 mg of this to be more effective than 400 mg of most other CoQ10 products.”

There’s no established recommended dose for CoQ10, but Golem says 100 mg per day is common. A 300-mg daily supplement is typically recommended to congestive heart failure patients, depending on their medications. Always talk to your doctor before taking any new supplement. CoQ10 is fine for most, but may interact with blood thinners and other medications. Also key: “Be consistent with taking it,” suggests Golem. “Benefits accumulate over weeks to months, not days. You need to give it time.”

The bottom line on CoQ10 for women

“CoQ10 isn’t a magic bullet or a replacement for foundational wellness habits—quality sleep, balanced nutrition and regular movement still reign supreme,” says Golem. “But for women over 50 who are doing those things and still feeling sluggish, especially if they have conditions that might lower their CoQ10 levels, supplementing with CoQ10 might be worth exploring. I don’t believe in universal recommendations for everyone, but the safety profile is excellent and the potential benefits—especially for energy and heart health—are backed by solid research.”
