Why 250mg of Yuzu Extract?

How Yuzu Extract works

Yuzu (Citrus junos) is a Japanese citrus fruit containing unusually high concentrations of hesperidin, narirutin, naringenin, and limonene - a combination of flavonoids and terpenes with documented antioxidant and anti-inflammatory activity. The flavonoid fraction supports endothelial function and capillary integrity via similar mechanisms to other citrus polyphenols.

Yuzu is also the only ingredient in this formula selected in part for its sensory contribution. The characteristic yuzu aroma - driven by linalool, beta-pinene, and limonene - is distinctive and pleasant, contributing meaningfully to palatability in a formula of 50 ingredients. Aromatic compounds have well-documented psychophysiological effects on mood and alertness, though these are a secondary consideration to the primary polyphenol content.

Key benefits

• High hesperidin and narirutin content - citrus polyphenol antioxidants
• Freeze-dried Japanese citrus peel, a traditional seasonal flavour
• Rich in hesperidin and narirutin, polyphenols occurring naturally in the citrus family
• Terpene complex (linalool, limonene) improves palatability
• Distinctive aromatic character - unique in all-in-one formulas
