Product Introduction

High-Purity Watercress Extract for Animal Health – Natural Phytonutrient Solution with ≥2.5% Glucosinolates 

Watercress Extract from Kingherbs Limited is a rich source of phytonutrients from Nasturtium officinale standardised to ≥2.5% glucosinolates and ≥1.0% phenylethyl isothiocyanate (PEITC) by HPLC. We use only pure water and food grade ethanol in our extraction method, which eliminates hazardous solvents while retaining the biological integrity. A fine brownish-yellow powder with 95% to 80 mesh particle size and 0.40-0.60 g/ml bulk density, for seamless integration in animal feed formulations. With over 25 years of botanical expertise and fully traceable approved planting bases, we regulate every aspect, from soil composition to harvest time, guaranteeing consistent active-ingredient content and avoiding the raw-material variations normally associated with sourcing from aquatic plants.

Watercress Extract Benefits

Your animals deserve the defence system of nature. This Watercress Extract is a powerful inducer of Phase II detoxification enzymes, especially glutathione S-transferases, which help the liver function in livestock exposed to environmental contaminants. The high ORAC value suggests a good radical scavenging activity that protects cellular integrity during time of oxidative stress such as weaning or transit.

Glucosinolate breakdown products naturally help clean airways to promote respiratory health. Quercetin and lutein improve the health of reproductive tissues and the immune systems of young animals in breeding operations.

Our water-ethanol extraction maintains the plant's natural synergy and deals with the instability problems of raw watercress, without the use of artificial ingredients. You obtain shelf-stable nourishment with no water-borne infections typical to fresh aquatic harvesting.
