The Active Ingredient Is: Mustard Seed Extract

Mustard seed extract is a plant-based phytonutrient source featuring glucosinolates that release bioactive compounds in your body. This extract type offers a range of natural nutrients for everyday wellbeing.

This version is pulled from mustard seeds and provided as an extract to bring the phytonutrient profile tied to traditional use in supporting overall health.

What Does Mustard Seed Extract Do?

Mustard seeds hold glucosinolates that, when digested, create compounds with antimicrobial properties and antioxidants. It helps support digestive processes through its fibre content and possible modulation of gut bacteria, in line with plant nutrient functions recognised by EFSA.
