Frequently Asked Questions

Miricell® is an award-winning, patent-pending, SA-GRAS affirmed rice germ extract, upcycled from rice milling byproduct and standardized to natural spermidine content at 1% and 2%. It delivers rice germ polyamines to support cellular health, healthy aging, and longevity.

Spermidine is a naturally occurring polyamine found in foods and living cells. It has attracted growing scientific interest for its potential role in autophagy, cellular health, and healthy aging.  In Miricell®, spermidine serves as the key standardization marker for its rice germ polyamines.

Autophagy is a natural cellular clean-up process that helps remove and recycle damaged cellular components. Miricell® is positioned as a natural autophagy activator that supports cellular maintenance, healthy aging, and longevity pathways.

No. Miricell® is not simply spermidine. Miricell® is a rice germ polyamine extract standardized to natural spermidine content. While spermidine is the key quality-control marker, Miricell® also delivers beneficial rice germ polyamines as part of its broader natural composition.

The term “Pure Spermidine” can mean different things depending on the product. In many cases, products marketed as “Pure Spermidine” use synthetic Spermidine Trihydrochloride (3HCl), a hydrochloride salt form of spermidine commonly used for its stability and handling characteristics.

Miricell® takes a different approach. Rather than supplying an isolated spermidine salt, Miricell® is a rice germ polyamine extract standardized to natural spermidine content (1% & 2%). In addition to spermidine, Miricell® provides naturally occurring rice germ polyamines within a plant-based, clean-label ingredient matrix designed for healthy aging and longevity formulations.

Rice germ is a natural, plant-based source of polyamines, including spermidine. Miricell® is upcycled from rice germ, a byproduct of modern rice milling, supporting a clean-label and more sustainable ingredient approach.

Unlike some spermidine ingredients derived from wheat germ, Miricell® is free from major food allergens and gluten, supporting broader formulation flexibility and consumer appeal.

Miricell® is produced from upcycled rice germ through a patent-pending process designed to concentrate naturally occurring rice germ polyamines while maintaining a plant-based, clean-label ingredient profile.

Miricell® combines rice germ-derived polyamines, natural spermidine standardization, plant-based positioning, low effective dose, and clean-label compatibility in one ingredient platform. 

It also supports brand differentiation in healthy aging and longevity products by offering a natural, rice germ-based alternative to synthetic or isolated approaches.

Miricell® is supported by published human clinical research and additional studies evaluating healthy aging, autophagy biomarkers, cognitive function, hair and nail health, cardiometabolic markers, and telomere-related outcomes. 

Miricell® is SA-GRAS affirmed, Prop 65 compliant, plant-based, non-GMO, allergen-free, Vegan certified, Kosher certified, and Halal certified. It is manufactured in a BRCGS Grade-A and FDA-inspected facility.

Miricell® is suitable for a wide range of dietary supplement and functional nutrition applications, including tablets, capsules, softgels, gummies, powders, stick packs, functional foods, and functional beverages designed to support healthy aging, cellular health, autophagy, and longevity.
