Prenulin® (L-Arabinose and Chromium — Pharmachem)

Evidence Level
Limited
0 Clinical Trials
3 Documented Benefits
2/5 Evidence Score

Prenulin® is a glucose-support blend of L-arabinose (a plant sugar from corn cob) and chromium picolinate (Chromax). Taken with sugary or starchy foods, it is designed to blunt the rise in blood sugar and insulin after meals. Supporting data come mainly from company-sponsored trials.

Studied Dose Taken before sugar-containing meals; dose per product.
Active Compound L-arabinose (from corn cob) plus chromium picolinate (Chromax).

Benefits

Post-meal blood sugar

In company double-blind, placebo-controlled studies, Prenulin reduced the blood-sugar and insulin spike after a sugar challenge; independent published data are limited.

Sugar metabolism

L-arabinose slows the digestion of table sugar (sucrose), while chromium supports healthy insulin action.

Carbohydrate management

Prenulin is positioned to soften the metabolic impact of sweet and starchy foods.

Mechanism of action

1

Sucrase inhibition

L-arabinose inhibits the sucrase enzyme, slowing the breakdown of sucrose into absorbable sugars and blunting the post-meal glucose rise.

2

Chromium and insulin

Chromium supports the action of insulin, helping cells take up glucose from the blood.

Clinical trials

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated.
Mild gas or bloating can occur from unabsorbed sugar.
Take with sugar-containing meals to assess tolerance.

Important Drug interactions

Diabetes medication — may add to blood-sugar lowering; monitor.
Take with meals, not on an empty stomach.
Tell your doctor if you manage blood sugar with medication.
