Walk into any health store or scroll through wellness ads online, and you’ll be met with a dizzying number of supplements claiming to boost energy, sharpen focus, grow hair, slow aging, and even prevent disease. With so many options available, it can be hard to know what’s actually worth trying—especially when it comes to aging and long-term brain health. While some supplements are overhyped or under-researched, others are gaining attention in the scientific community for their potential benefits. One neuroscientist has even taken to social media to claim that one supplement can slow down aging:
If you’re looking for a supplement that may support healthy aging and possibly even help protect the brain from age-related decline, one neuroscientist has a surprising recommendation. It’s not a household name just yet, but it’s showing real promise in early studies. Here’s one supplement you may want to ask your doctor about before adding it to your routine.
What Is Quercetin?
Quercetin is a natural plant compound found in fruits and vegetables like apples, onions, berries, and leafy greens. It’s part of a group of antioxidants called flavonoids, which help protect your cells from damage caused by free radicals—unstable molecules that can contribute to aging and disease. Because it’s so common in everyday foods, many people already get small amounts of quercetin in their diets, but it’s also available in supplement form if you want a more concentrated dose. (Remember to check with your doctor before taking any new supplement).

How It May Help With Aging and Brain Health
Quercetin has gained attention for its potential role in slowing down the aging process and supporting brain health. Some studies suggest that it can reduce inflammation, improve immune function, and protect brain cells from oxidative stress, and all of these are linked to age-related decline and diseases like Alzheimer’s. It may even help clear out older cells that stop functioning properly and contribute to the signs of aging. While research is still ongoing, early findings are promising enough that some experts, including some neuroscientists, are paying close attention to this antioxidant.
How to Take It Safely
If you're thinking about adding quercetin to your routine, it’s a good idea to talk to your doctor first—especially if you take medications or have any health conditions. Quercetin supplement doses are typically 500 to 1,000 mg per day, and some supplements combine it with vitamin C or bromelain to help with absorption. Remember: supplements are not magic cures and they all work best when paired with a healthy lifestyle, including a balanced diet, regular exercise, and good sleep habits.
