Prevagen Regular Strength vs Extra Strength vs Professional Formula: What the Numbers Mean

Prevagen is one of the most searched-for supplements in the US, and one of the most confusing to buy because the boxes look alike. This guide covers what is actually different between the versions, using only what is printed on the label. It is not medical advice; read the Supplement Facts panel and talk to a pharmacist about any supplement.

The one thing that changes: milligrams of apoaequorin

Every Prevagen product has the same active ingredient, apoaequorin, plus vitamin D. The strength name tells you how many milligrams of apoaequorin are in one capsule or chewable tablet.

The serving is one per day for every version. A 30 count is a 30-day supply, a 60 count is 60 days.

Capsule or chewable?

Same strength, different form. Chewables are for people who do not want to swallow a capsule. Regular Strength chewables come in mixed berry and orange; Extra Strength chewables come in mixed berry only. There is no Professional Formula chewable.

Which one are you looking for?

If you have only heard "Prevagen" with no other detail, the version most heavily advertised on TV is Regular Strength capsules, 30 count. "The stronger one" or "extra strength" is 20 mg. "Professional" or "the one my doctor mentioned" is the 40 mg Professional Formula, which was originally sold through healthcare practitioners.

How to read the box fast

• Front of box: the strength name and the mg number are both printed on the front. Match the mg number, not the color, since packaging changes.
• Form: "Capsules" or "Chewables" is printed under the strength name, with the flavor for chewables.
• Expiration: printed on the bottom flap. DR OTC ships only product with 12 or more months remaining.
