You know the feeling.

The word on the tip of your tongue. The keys you've already looked for twice. The appointment you would have sworn was next week. Walking into a room and forgetting why.

But it's not just the moments...

It’s what comes with them.

The quiet worry that you used to be sharper than this.

Person in a quiet reflective moment

The small, private embarrassment every time someone has to fill in the blank you should have had.

The guilt of knowing your spouse or your kids are getting whatever is left of you after a day of holding it together.

And the self-blame that you noticed this months ago and told yourself you’d do something about it.

Why most supplements get brain health wrong.

There are a lot of supplements that attempt to address brain aging, ranging from single ingredients to long lists of brain-adjacent compounds. But ingredient count is not the real issue.

Despite all these different approaches, many formulas still fall flat, because they're aimed at the wrong thing.

Most brain supplements target short-term effects: a quick feeling of focus or a burst of alertness. And that does help some people. Who wouldn't want that? But it's patching a surface leak while the underlying system that caused the leak is still unaddressed. It might help in the moment, sure but it doesn't support what's underneath.

Targeting that short-term boost is easy. Supporting the underlying process of healthy brain aging is harder, because it requires a more robust approach.

The brain is complex. A healthy mind doesn't depend on one ingredient or one effect. It depends on multiple systems working together, every day, consistently over time.

Growth

The brain forming and maintaining the connections that thinking depends on.

Maintenance

The everyday biochemical housekeeping that keeps neurons supplied and running clean.

Signaling

The electrical day-to-day that turns those connections into focus, recall, and steady mood.

Resilience

The brain's own capacity to protect what it has built.

That's the approach most of the supplement industry never takes. It's harder. It's less profitable. It demands real accountability. But it's the only one that actually stops patching surface leaks.

Doctors who couldn't find something they could recommend.

Our patients kept asking what they could take to support memory, focus, and healthy brain aging. We saw gimmicky gummies, exotic-sounding ingredients, formulas that were too expensive to take every day, and labels packed with 10+ ingredients that didn't meet our evidence threshold.

When you actually want to start supporting the necessary brain processes for healthy brain aging, and not just chasing an artificial boost or competing to see who can squeeze the most ingredients in a powder, the formula looks fundamentally different from what's on the market.

That's the standard we applied. That's what we were looking for.

Verified review from a hesitant buyer who trusted the doctor-led, restrained formulation Customer review about the doctors

You've probably been let down before.

Many brain health supplements fall into one of two patterns.

1

They chase a feeling.

Some formulas are built to make you feel more alert in the moment, often by leaning on stimulants or fast-acting nootropic ingredients. You may feel more alert in the moment, but that is not the same as supporting the deeper systems involved in healthy brain aging that matter to you.

2

They try to support everything.

They claim to support brain health, gut health, immune support, energy, stress, and general wellness all on one label. A jack of all trades is a master of none.

We're doctors, not career supplement makers. We never intended to make one.

Anyone can make a supplement. Not everyone has patients asking them which one to take. And when you're sitting across from someone who is trusting you for answers about their health, the stakes are higher, and you think differently about what you're willing to put your name on.

We built Mentaid because we heard the need, we saw the gap, and we felt we had to.

Not a formula built around short-term effects or label impressiveness. Daily support for the brain processes that actually matter for healthy brain aging, the ones most of what's on the market never touches because they aren't flashy.

A required cofactor for healthy nerve-signal transmission and neuronal excitability, the day-to-day electrical housekeeping behind focus and steady mood. We use the glycinate form because it's well suited for daily use and generally gentle enough to take consistently.*

The differentiator

Lithium Orotate

You've seen the headlines about lithium and brain health. And as the science kept returning to it, so did we. Science doesn't keep returning to something unless there's a reason.


We know lithium carries baggage. For many people, the word brings to mind prescription medication, high doses, and medical monitoring. Most brain supplements leave it out. Maybe because it sounds intimidating. Maybe because it takes too much explaining.


We didn't.

This isn't prescription lithium, which is used at much higher doses and requires regular lab monitoring. We used lithium orotate.


And it isn't the arbitrary "5mg" many supplements default to, a dose that was never matched to any of the research that made lithium interesting in the first place. We dose lithium orotate in micrograms, in the low range the research actually points to: intentional by design, modest enough for daily use, and far below prescription-dose territory.*

What customers are saying

Customer review about the ingredients Customer review about the lithium dose Customer review about the capsules being easy to take

You ask a lot of your mind. Give it what it needs every day.

Staying mentally sharp is one of the few things that touches everything: your work, the people you love, and whether you still feel like yourself.

The right nutrients support the systems behind memory, focus, and clear thinking. And clear thinking touches your work, your relationships, your confidence, and more.

Sleep, exercise, managing stress, and eating well all support how your mind holds up, and so do specific nutrients like lion's mane, B vitamins, magnesium, and trace lithium. The trouble is, in a world that asks your brain to track more than it was ever built to, the basics don't always cover it. Especially past 40, when your brain's support needs start to change.

Giving your mind steady, daily support is the kind of thing that works over time, not overnight, which is why taking Mentaid every day can help.

The goal was never to become someone new. It's to stay the person you already are, the sharp one, the one you can count on.

And there's no easier, hassle-free way to never miss a day than with our subscription options below.

Who Should Take Mentaid?

Anyone who's concerned about their aging brain and wants to do something about it.

Recommended Use

Take 2 capsules by mouth daily.

A few things you might be wondering
How long until I see results?

Mentaid is designed for consistent, daily brain support. Think of it less like a performance enhancer and more like a brain multivitamin. Some users notice changes. Others may not notice an immediate difference, but that doesn't mean it isn't working. The goal is ongoing support for your brain, not a dramatic short-term effect.
What fillers or additives are in Mentaid?

None. Every capsule contains only the active ingredients listed on the label, plus the capsule itself. We know that many tolerability issues people experience with supplements come from fillers and additives, not the ingredients themselves. That's why we kept it clean - just what's on the label and nothing more.
Is Mentaid tested?

Yes. Mentaid is thoroughly tested at multiple stages of manufacturing. Every batch is tested for both purity and contaminants, and comes with a Certificate of Analysis.

Is Mentaid manufactured in the United States?

Yes! Mentaid is manufactured in the state of Georgia in the United States.
Isn't lithium a prescription medication?

Lithium carbonate is a prescription medication used to treat bipolar disorder, and that's likely what comes to mind. But Mentaid contains lithium orotate, a different compound entirely. Lithium orotate is a naturally occurring mineral salt that delivers lithium at nutritional doses, far lower than what's found in any prescription. It's available over the counter and has been used as a dietary supplement for decades. Think of it less like a drug and more like a trace mineral supplement, similar in concept to magnesium or zinc.*
How much lithium is in Mentaid?

Our formula contains 5 mg of lithium orotate, which provides approximately 200 micrograms of elemental lithium.

To put that into context, naturally occurring lithium in some drinking water sources can reach similar levels.
Is lithium safe?

Lithium has been studied for decades.

At prescription doses, it requires monitoring and lab draws. At low, supplemental doses, lithium has a very different safety profile.

We formulated conservatively and thoughtfully, with daily use in mind.

If you have a medical condition, especially a thyroid or kidney condition, or take medications that may interact with lithium, we recommend speaking with your healthcare provider.

For more information, see our Guide to Lithium Orotate.
Why haven't other supplements included lithium?

If a product claims to support brain health but ignores lithium, it’s worth asking if they're even focused on "brain health".
I have an MTHFR variant. Can I take Mentaid?

Common MTHFR gene variants are present in many people.

The CDC states:

"You may have heard that if you have an MTHFR variant, you should avoid folic acid and should take other types of folate, such as 5-MTHF. However, this is not true. People with an MTHFR gene variant can process all types of folate, including folic acid."

Large clinical studies evaluating B vitamins for cognitive support have commonly used non-methylated forms. These forms have decades of safety and research behind them.

For this formula, we selected forms supported by strong clinical evidence and safety data. If you have a diagnosed metabolic disorder or specific medical concerns, consult your healthcare professional.
Why didn't Mentaid include ______ ?

Every ingredient in Mentaid was selected based on the strength and quality of available human clinical research. While many ingredients show promise in preclinical or animal studies, human outcomes do not always mirror early findings.

We prioritize well-designed human trials, safety and tolerability data, and how each ingredient functions within a cohesive formulation.

We continuously review emerging research and will refine the formula if and when new, high-quality human evidence supports it.
Is Mentaid allergen-free?

Yes. Mentaid is free from all 9 major allergens recognized by the FDA. Our formula contains no:

  • Milk
  • Eggs
  • Fish
  • Shellfish
  • Tree nuts
  • Peanuts
  • Wheat
  • Soy
  • Sesame

Our capsules are made from methylcellulose (a plant-based cellulose), and we use no fillers, binders, or excipients of any kind, just the active ingredients.
