01 — What is MethoxyMemory®

A next-generation citrus ingredient for brain health

MethoxyMemory® is a next-generation nutraceutical ingredient designed to support brain health. It is based on an exclusive citrus-derived antioxidant complex naturally rich in methoxyflavonoids.

Citrus flavonoids are increasingly recognized for their role in supporting brain health. Their neuroprotective properties are linked to their ability to reduce oxidative stress and inflammation, helping protect neurons and maintain cognitive function.

Obtained through the upcycling of citrus by-products, it transforms an underutilized side stream into a high-value nutraceutical ingredient, combining sustainability and GMP manufacturing.

04 — Science & mechanism of action

Why methoxyflavonoids matter for brain health

A carefully standardized composition of polyphenols, flavonoids, and methoxyflavonoids designed to deliver a distinctive antioxidant profile for cognitive health formulations.

Polyphenols

Gallic acid

A naturally occurring polyphenol that contributes to the extract’s antioxidant profile and is widely studied for its biological activity.

Flavonoids

Naringin & Narirutin

Characteristic citrus flavanones known for their antioxidant properties and their role in supporting cellular protection.

Methoxyflavonoids

Nobiletin

The principal methoxyflavonoid in the extract and the key marker used for standardization, contributing to its distinctive phytochemical profile.

–OCH3

Methoxyflavonoids are flavonoids containing methoxy groups (–OCH₃). This structural feature is associated with improved stability and bioavailability and may contribute to enhanced biological activity compared with non-methoxylated flavonoids.

Marker compound · standardization

Nobiletin — the principal methoxyflavonoid

The extract is standardized to nobiletin, a polymethoxylated flavonoid naturally found in citrus. Its multiple methoxy groups (–OCH₃) are associated with improved stability and bioavailability compared with non-methoxylated flavonoids.

Nobiletin is widely studied for its antioxidant and neuroprotective potential.

Step 02
Digestion

Dynamic gastrointestinal digestion is reproduced under physiologically relevant conditions.

Step 03
Bioaccessible fraction

The soluble intestinal fraction is collected after digestion for biological evaluation.

Step 04
Brain effect

The bioaccessible fraction is tested in a neuronal cell model to assess antioxidant and neuroprotection-associated responses.
