01 / THE DETAILS

What’s inside this formula?

Life Extension’s PQQ — 20 mg is listed here in the pqq collection. This article looks at the selected 30 vegetarian capsules; one-capsule serving pack, then puts its ingredients into context.

FROM THE MANUFACTURER’S LABEL

The manufacturer lists 20 mg PQQ (pyrroloquinoline quinone) disodium salt per vegetarian capsule. The bottle contains 30 capsules.

Check the original label ↗

Pyrroloquinoline quinone, or PQQ, is marketed around cellular energy and cognitive performance. Human studies are much more limited than the mechanistic marketing suggests. A few short trials have explored memory measures, but those results need replication and do not establish that a supplement creates lasting mental sharpness or prevents cognitive decline.

The pack details above come from the manufacturer. Ingredient research below does not establish the effects of this exact product or independently verify its contents.

02 / BENEFITS, IN PERSPECTIVE

Where might it be useful?

01

Preliminary cognition research

One short randomized trial reported improvements in selected cognitive measures with a particular PQQ preparation.

02

A formulation worth identifying

The amount and preparation help compare a product with the research, while leaving the clinical uncertainty visible.

THE EVIDENCE LENS

What the research can — and cannot — tell us

The cited trial examined a defined dose over a limited period and does not prove dementia prevention, longer life or a general energy boost. Small studies and multiple cognitive outcomes warrant caution. Findings for the studied preparation do not verify the exact branded formula in this catalogue.

03 / A CLOSER LOOK

What deserves your attention?

This is the standalone PQQ formula, without a declared CoQ10 amount. The label strength alone does not establish improved energy, cognition or a personal need for supplementation.

Suitability comes before strength

Long-term safety and benefits are not well established. Review use during pregnancy, medical treatment or chronic illness, and seek assessment for new memory difficulties rather than relying on a supplement.

Dietary details for this product

Vegetarian The official manufacturer page explicitly marks this whole product vegetarian. A separate vegan claim is not confirmed.

A dietary label and an allergy assessment answer different questions. Check every ingredient, the capsule or softgel materials and the allergen statement on the pack you receive. If you take medicines, have a health condition, are pregnant or are choosing for a child, discuss the full formula with a qualified clinician.
