The daily brain-health formula, built on human research.
Anyone who's concerned about their aging brain and wants to do something about it.
Take 2 capsules by mouth daily.
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, which is available over the counter and has been used as a dietary supplement for decades.
For more information, see our Guide to Lithium Orotate.
At prescription doses (600-1800mg/day) and prescription forms (lithium carbonate), lithium has a narrow safety index, requires monitoring and lab draws. At supplemental doses (5mg/day) and supplemental forms (lithium orotate), lithium has a very different safety profile.
We formulated with conservatively and thoughtfully, with the form and dose amenable for daily use in mind.
A peer-reviewed toxicology study found that lithium orotate 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.
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.
This is also lower than most other lithium orotate supplements on the market, which most commonly contain ~120 mg of lithium orotate, which provides 5mg of elemental lithium.

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."

The best clinical studies evaluating B vitamins for cognitive support have used non-methylated forms, with success.
If you have a diagnosed metabolic disorder or specific medical concerns, consult your healthcare professional.
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.
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.
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.
Yes! Mentaid is manufactured in the state of Georgia in the United States.
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.
Yes. Mentaid is free from all 9 major allergens recognized by the FDA. Our formula contains no:
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.
