Founded by a team of food scientists, process engineers, and market developers with nearly a century of combined food industry experience, Quintessence Nutraceuticals brings together a consortium of experts with an intensely committed passion for improving global health and wellness on a holistic level.

It began with a desire to mitigate food insecurity and chronic malnutrition among children in developing countries. The team knew the solution needed to be sustainable and regionally applicable. Following nearly a decade of research and development, NutraIso® was born.

Using patented enzymatic hydrolyzation technology, Quintessence extracts the nutraceutical and pharmacological isolates from the bran and germ layers of rice. No longer rice, but a derivative thereof, plant-based NutraIso is an all-natural, highly bioavailable and bioactive nutraceutical ingredient producing measurable and life-changing results. These benefits are clinically proven to address health concerns across populations and life stages: from prenatal to pre-diabetic, infant to senior wellness.

An experienced and agile team of professionals, each expert in their roles—they seek to answer what is the greatest question of our time: “How do we make life-changing nutrition more accessible to nutritionally deficient populations worldwide?”

In partnering with global food and beverage companies, Quintessence Nutraceuticals is strategically focused on incorporating NutraIso into a range of consumer products and condition-specific foods, making a paradigm changing difference in enhancing health and wellness naturally.

Whom We Support

Sustainable Nutrition International

Changing the life of a child not just for a day but for a lifetime

Sustainable Nutrition International (SNI) is an independent 501c3 Charitable Organization registered in the United States and focused on delivering bioactive nutrition to nutrient-deficient populations. SNI’s primary mission is to remediate chronic malnutrition in children through early intervention with proprietary and clinically documented nutraceutical formulations for lactating mothers and their breastfed infants.

The documented capacity of NutraIso to remediate the physical and cognitive effects of chronic malnutrition among breastfed infants is at the heart of SNI’s program initiatives. Phase 1 early intervention field clinical trials in Central America demonstrated the significant impact NutraIso can have in undernourished populations.  In 2013, the NutraIso technology received the Patents for Humanity Award for remediating chronic malnutrition in lactating mothers and their breastfed infants.  

There are 165 million children under the age of 5 living in a state of chronic malnutrition. Between birth and 24 months of age, nutrition is critical for physical growth and cognitive ability, as well as building a strong immune system that supports persons through the adult years. Chronic malnutrition and inadequate dietary intake in infancy can lead to stunted growth and decreased mental development, leading to a lifetime of underachievement and socioeconomic struggle.

This perpetuation of poverty can have a multi-generational and whole-community impact long-term. Sustainable Nutrition International is working to provide life-changing nutritional intervention to these at-risk populations, and Quintessence Nutraceuticals is proud to be associated with that effort.

What does bioavailable mean?

Bioavailability relates to the capacity of a nutrient to be absorbed into the gastrointestinal system and bloodstream, making the nutrient more bioactive (efficacious) in the human body for the health and wellbeing of the recipient. The NutraIso® patented extraction process “pre-digests” the phytonutrients in the germ and bran layers of rice so the human body can absorb and utilize the maximum amount of its bioavailable nutrients.

What does enzymatic hydrolyzation mean?

Hydrolyzation involves using specific enzymes to cleave a substance into smaller component parts. The more enhanced the enzyme hydrolyzation, the greater the bioavailability of the proteins, fats, carbohydrates, and micro/macro nutrients are for absorption in the human digestive system.

What is a phytonutrient?

A phytonutrient is a natural compound derived from plants that provides documented beneficial qualities for human health.
