Your brain isn't what it used to be.
AARP reviewed every brain supplement and couldn't endorse a single one.
As a doctor, I couldn't either, so I decided to fix that.
Save your brain.

You know the feeling.
The word on the tip of your tongue.
It's there. You just can't grab it.
The keys you've looked for twice.
Right where you checked already.
The appointment you'd have sworn was next week.
But it's today. Or was yesterday?
Walking into a room and forgetting why.
Then standing there trying to remember.
But it's not just the moments...
It's what comes with them.
-
The quiet worry that you used to be sharper than this.
-
The embarrassment when someone fills in your blank.
-
The guilt your family gets whatever's left of you.
-
The self-blame you noticed months ago and did nothing.
As doctors, we saw the need, but couldn't find something we could recommend.
Our patients kept asking what they could take to support their aging brain. When we looked at what was out there, we couldn't find a product we felt we could put our name behind.
Anyone can make a supplement and claim to help with brain aging. Not everyone has patients sitting across from them, trusting us with their health, where the stakes are higher, and you think differently about what you're willing to put your name on.
So we built Mentaid.
We're doctors, not career supplement makers. We never intended to make one, but we heard the need, we saw the gap, and we felt we had to.

You ask a lot of your mind. Give it what it needs every day.
Your brain is one of the few things that touches everything: your work, the people you love, and whether you still feel like yourself.
You’ve probably been told to sleep, exercise, manage stress, eat well, and treat any hearing loss. And you’ve probably tried all that, only to find it isn’t always enough.
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.
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.
And there’s no easier, more hassle-free way to never miss a day than with our subscription options below.

A few things you might be wondering
Is lithium orotate 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.
A peer-reviewed toxicology study found it has been "marketed for decades as a supplemental source of lithium with few recorded adverse events." 1
Another peer reviewed source notes "there are no reported
cases of death or serious side effects in more than 40 years of lithium
orotate use in Europe and the U.S." 2
Another source notes "adverse effects have not been reported for low doses (lithium orotate 5 to 20 mg)." 3
For more information, see our Guide to Lithium Orotate.
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.
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.
Why haven't other supplements included lithium?
We can't speak for every other product, but lithium is often left out because people are sometimes hesitant about it due to the stigma of prescription lithium. But, 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.
"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.
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 to support your brain health as you age.
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.
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.
