What is Prevagen used for?
Prevagen is used as a daily dietary supplement by adults looking for brain health support. Shoppers often compare it with other memory support supplements and brain health vitamins — but Prevagen is not a medication. It should not be treated as a treatment for memory loss, dementia, Alzheimer's disease, or any diagnosed medical condition.
If you are noticing new or worsening memory concerns, the right first step is a conversation with a healthcare professional, not a supplement purchase. What Prevagen offers is a daily brain health supplement routine built around apoaequorin and vitamin D — two ingredients that define the brand and set it apart from competitors like Neuriva, which uses a different active ingredient profile.
Shoppers typically turn to Prevagen when they want to add a dedicated brain health supplement to their daily stack, when they are comparing strengths to decide between Regular and Extra Strength, or when they prefer a chewable tablet over a capsule. The product cards below cover all four current formulas.
Daily brain health support
Adults who want a daily supplement formulated for brain health use Prevagen as part of a broader wellness routine. It is not a treatment for any condition.

What ingredients are in Prevagen?
Every Prevagen formula shares two primary active ingredients. The dose of apoaequorin varies by formula; vitamin D is consistent at 50 mcg across the full product line.
| Ingredient | Amount by formula | Notes |
|---|---|---|
| Apoaequorin | 10 mg / 20 mg / 40 mg | Primary active ingredient; a calcium-binding protein originally derived from the Aequorea victoria jellyfish |
| Vitamin D | 50 mcg (all formulas) | Consistent across all Prevagen products; supports general physiological health |
Inactive ingredients — fillers, coatings, and flavors in the chewable tablet — vary by SKU. Always verify on the Supplement Facts panel on each individual product page or product label before purchasing.
Read the Ingredient Guide →Apoaequorin
A calcium-binding protein first isolated from the Aequorea victoria jellyfish. Present in all Prevagen formulas. The dose — 10, 20, or 40 mg — is the key difference between Regular, Extra Strength, and Professional Formula.
10 – 40 mg depending on formulaVitamin D
A fat-soluble vitamin included in every Prevagen formula at a consistent 50 mcg dose. Plays a role in general physiological function. Also present in the chewable tablet format.
50 mcg · all formulasHow does Prevagen work?
Prevagen's formula is built around two ingredients: apoaequorin and vitamin D. Apoaequorin is the branded active ingredient that differentiates Prevagen from most other brain health supplements on the market, including Neuriva, which uses phosphatidylserine and coffee cherry extract instead.
Apoaequorin was originally derived from a protein found in the Aequorea victoria jellyfish. Prevagen uses a lab-manufactured version of this calcium-binding protein. The key functional difference between Prevagen formulas is simply the amount of apoaequorin per serving — and that number is the clearest decision point when choosing between Regular Strength, Extra Strength, and Professional Formula.
Vitamin D is present in every Prevagen formula at a consistent 50 mcg per serving. It is a widely used ingredient with established roles in physiological health, and it is the same across all four products, including the chewable tablet.
| Formula | Apoaequorin per serving | Format |
|---|---|---|
| Prevagen Regular Strength | 10 mg | Capsule |
| Prevagen Extra Strength | 20 mg | Capsule |
| Prevagen Professional Formula | 40 mg | Capsule |
| Prevagen Extra Strength Chewables | 20 mg | Chewable tablet |

Prevagen vs Neuriva: quick comparison
Two of the most searched brain health supplements — different ingredients, different approaches.
Shoppers frequently compare Prevagen vs Neuriva because both are OTC brain health supplements sold without a prescription. The comparison works the other way too — Neuriva vs Prevagen comes up just as often when buyers want to know which product fits their situation. The short answer: they are built on entirely different active ingredients.
Prevagen uses apoaequorin (10–40 mg depending on formula) and vitamin D as its two primary ingredients. Neuriva's formula takes a different approach, centering on phosphatidylserine and coffee cherry extract — neither of which appears in any Prevagen product.
Neither brand carries FDA approval for treating, curing, or preventing any disease. Both are dietary supplements subject to DSHEA regulations. The FTC has also scrutinized Prevagen's efficacy advertising. We are not in a position to say one is better than the other — they are different products built around different ingredient strategies.
