I don’t know about you, but some mornings I open the fridge and completely forget what I was looking for. Was it the creamer? The leftovers? Or just peace of mind? Getting older comes with its perks—more wisdom, more patience, more stories to tell. But let’s be honest: sometimes the memory lapses, brain fog, and occasional “wait, what was I saying?” moments sneak in too.
The good news? Just like we take care of our heart, bones, and joints, we can also take care of our brain. And while lifestyle choices like sleep, movement, and healthy food always come first, supplements can give us a little extra edge. Today, I want to walk you through five supplements that research supports for brain health as we age—and share a few “everyday life” stories along the way.
1. Omega-3 Fatty Acids: The Brain’s Favorite Fuel
The first time I realized the power of omega-3s was when a friend told me she felt like her brain was “squeaky clean” after taking them for a few months. And she wasn’t wrong. Omega-3 fatty acids—especially DHA and EPA—are literally part of our brain’s building blocks.
They help keep brain cells flexible, support memory, and may even slow down age-related decline. If you’re not a big salmon or sardine eater, a supplement can fill the gap.

Pro tip: I take mine in the morning with breakfast. If I forget, I’ll find the bottle staring at me from the counter like, “Seriously? Again?”
2. Vitamin D: Sunshine for Your Mind
Here’s the thing: many of us don’t get enough vitamin D, especially if we spend our days indoors, slather on sunscreen (as we should), or live in colder states. I once went an entire winter without realizing how sluggish and foggy I felt—until my doctor checked my vitamin D levels. Spoiler: they were low.
Vitamin D supports brain health by protecting neurons and boosting mood. Think of it as sunshine in a capsule.

And trust me, when the February blues hit, this little boost can feel like someone opened the blinds in your brain.
3. B-Complex Vitamins: The Brain’s Energy Pack
Ever had one of those days where your brain feels like a slow-loading computer? That’s where B vitamins—especially B6, B12, and folate—come in. They help your body turn food into energy and keep your nervous system running smoothly.
A colleague once told me she could literally “feel her brain boot up” after starting a B-complex supplement. While it’s not quite like charging your phone, the right levels of B vitamins can help you stay sharp and less drained.

I like to think of them as the coffee crew for your brain—minus the jitters.
4. Curcumin: The Spice That Keeps Things Bright
If you’ve ever cooked with turmeric, you know it stains everything—your fingers, your countertop, maybe even your favorite wooden spoon. But it also brings along curcumin, the active compound that helps fight inflammation.
Why does that matter? Because inflammation in the brain can affect memory and focus. Curcumin supplements (especially those combined with black pepper for better absorption) may help keep your brain clear and resilient.
👉 Try: [Turmeric Curcumin with Black Pepper on Amazon]
When I take mine, I joke that I’m seasoning my brain from the inside out. No turmeric-stained kitchen required.
5. Magnesium: The Calm Connector
Here’s my confession: I didn’t think much about magnesium until I had a string of restless nights. Someone suggested magnesium, and within a week, I noticed not just better sleep but also a calmer mind during the day.
Magnesium supports nerve function, helps regulate neurotransmitters, and plays a role in memory and learning. It’s like giving your brain a gentle hug.
👉 Try: [Magnesium Glycinate Supplement on Amazon]
And no, it won’t solve every sleepless night—but it sure helps when your brain won’t stop replaying the grocery list at 2 a.m.
How to Choose (and Actually Stick With Them)
Now, here’s the tricky part: supplements only work if you actually take them. I’ve had bottles that lived in my cabinet like museum pieces, unopened and untouched. The best system I found was keeping a small pill organizer by my coffee maker. That way, every morning when I brew my cup, I remember my brain boosters too.
Always check with your doctor before starting something new—especially if you’re on other medications. Supplements aren’t magic, but paired with healthy habits, they can help you feel more like yourself and less like “that person who forgets what they were saying mid-sentence.”
A Little Extra for You
I’ll wrap this up with one thought: caring for your brain is a lifelong project, not a one-time fix. The choices we make now—what we eat, how we move, what we supplement—shape how sharp and vibrant we’ll feel years down the road.
