SteviUp® M2 (Next-Gen Stevia Reb M — Layn USA)

Superior Water Solubility

SteviUp M2 has superior water solubility compared with conventional stevia Reb M — addresses formulation challenges of stevia products.

Supported by Trial 1

More Sugar-Like Taste

Optimized to deliver more sugar-like taste with shorter lingering sweetness — major taste advance for natural sweeteners.

FDA GRAS Approved

Reviewed by FDA and recognized as GRAS for use as general-purpose sweetener in food and beverage products.

Supported by Trial 1

Enzymatic Bioconversion (Non-GMO)

Derived through enzymatic conversion of purified steviol glycosides — clean-label, non-GMO, plant-based.

Customizable

Can be customized to complement specific food and beverage products.

Sustainability and Scalability

Layn invested in R&D for breeding new stevia leaf varieties and optimizing manufacturing processes; sustainable scalable production.

Rebaudioside M2 Activity

Reb M2 is steviol glycoside variant produced via enzymatic conversion; differs from natural Reb A and Reb M in glycoside chain pattern; provides superior taste/solubility profile.

Enzymatic Conversion Process

Enzymes convert one steviol glycoside to another; allows production of less abundant but more functional glycosides; more efficient than agricultural cultivation alone.

No Insulin Response

Like other steviol glycosides, does not stimulate insulin release.

Improved Taste Profile Mechanism

Reb M2's specific structure activates sweet taste receptors with reduced activation of bitter receptors — cleaner overall taste.

This is generic-stevia evidence, not a trial of SteviUp M2, and supports glucose-neutrality of steviol glycoside sweeteners as a zero-calorie sugar substitute rather than any metabolic-treatment benefit.
