FOR IMMEDIATE RELEASE
Solaren International announces formulation update to PhenCapz Plus, replacing synephrine HCl with Advantra‑Z®
ORLANDO, Fla. — December 15, 2025 — Solaren International today announced an update to the formulation of its flagship metabolic support supplement, PhenCapz Plus, replacing synephrine HCl with Advantra‑Z®, a clinically studied Citrus aurantium extract recognized for its safety and thermogenic benefits.
Advantra‑Z®, developed by Innophos, is a self‑affirmed GRAS ingredient standardized from bitter orange and supported by multiple human efficacy studies and a comprehensive safety dossier. According to Innophos, the extract delivers thermogenic and energy‑supporting benefits without the undesirable stimulant effects associated with other metabolic ingredients.
Solaren International said the transition reflects its commitment to evidence‑based innovation and improved patient outcomes.
“PhenCapz Plus has always been designed to support safe, sustainable metabolic momentum,” said Jennifer, founder and creative lead of Solaren International. “Advantra‑Z® allows us to strengthen that mission by offering a cleaner safety profile, strong clinical backing and reliable thermogenic support that aligns with what both providers and patients expect from modern weight‑management tools.”
Advantra‑Z® has been shown in clinical research to support increased metabolic rate, fat oxidation and exercise performance. Its safety profile and lack of harsh stimulant activity make it a preferred alternative to traditional synthetic synephrine sources.
Solaren International said the updated PhenCapz Plus formula maintains the product’s intended benefits while enhancing tolerability for a broader range of patients seeking support with energy, appetite control and weight‑management programs.
Healthcare providers will begin receiving updated product information and educational materials this month. The company said no changes have been made to dosing recommendations or usage guidelines.
