Neuroscientist Says These Powerful Supplements Can ‘Slow Down’ The Aging Process And Prevent Brain Diseases

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.
