What is TR90? Nu Skin's ageLOC Weight Management System Explained
TR90 is a 90-day weight management system developed by Nu Skin Enterprises that applies the company's proprietary ageLOC gene expression technology to body composition. Unlike conventional weight loss programs that focus solely on caloric restriction, TR90 targets the genetic mechanisms that regulate how the body stores fat and maintains lean muscle — using a combination of supplements, meal replacement shakes, and a structured eating protocol to produce sustainable body composition changes.
In one sentence: TR90 is Nu Skin's 90-day ageLOC-powered weight management system that uses gene expression science, targeted supplements, and protein shakes to support fat loss while preserving lean muscle mass.
Key Facts About TR90
- Developer: Nu Skin Enterprises, using ageLOC gene expression technology
- Program length: 90 days (with optional 30-day starter kits)
- Core technology: ageLOC — targets Youth Gene Clusters (YGCs) related to body composition and metabolic function
- Primary goal: Fat loss while preserving lean muscle mass
- Key products: TR90 JumpStart, TR90 Control, TR90 GreenShake, TR90 TrimShake
- Program approach: Supplements + meal replacement shakes + structured eating protocol
- Available from: NuBodyRx.com, an authorized Nu Skin retailer
The Science Behind TR90
TR90 is built on Nu Skin's research into Youth Gene Clusters (YGCs) — groups of genes that regulate youthful cellular function, including genes involved in metabolism, fat storage, and muscle maintenance. As we age, the expression of these gene clusters shifts in ways that make it progressively harder to lose fat and maintain lean muscle — a phenomenon sometimes called "metabolic aging."
TR90's formulas are designed to favorably influence the YGCs associated with body composition, supporting the body's natural ability to burn fat efficiently while protecting lean muscle tissue. This gene expression approach distinguishes TR90 from conventional weight management programs that rely solely on caloric restriction or stimulant-based fat burners.
TR90 Products Explained
TR90 JumpStart
The JumpStart is the foundation of the TR90 program — a supplement designed to be taken at the beginning of the program to prepare the body for the 90-day transformation. It supports the initial metabolic shift needed to transition the body toward more efficient fat burning while protecting lean muscle.
When to use: Days 1–30 of the TR90 program as the program initiator.

TR90 Control
TR90 Control is a supplement taken with meals to support appetite management and healthy blood sugar levels. It helps reduce cravings and supports the body's ability to manage glucose — a key factor in preventing fat storage and maintaining energy levels throughout the day.
When to use: Taken with meals throughout the 90-day program.

TR90 GreenShake
The TR90 GreenShake is a high-protein meal replacement shake formulated to support lean muscle preservation during the TR90 program. It provides a balanced macronutrient profile with high-quality protein to support muscle maintenance, fiber for satiety, and a blend of vitamins and minerals for nutritional completeness.
When to use: As a meal replacement 1–2 times daily throughout the program.

TR90 TrimShake
The TR90 TrimShake is an alternative protein shake option within the TR90 system, available in chocolate and vanilla flavors. Like the GreenShake, it provides high-quality protein for lean muscle support and serves as a convenient meal replacement within the TR90 eating protocol.
When to use: As a meal replacement alternative to the GreenShake.
TR90 Program Structure
The TR90 program is structured as a 90-day commitment with a specific protocol:
Phase 1: JumpStart (Days 1–30)
The first 30 days focus on initiating the metabolic shift. The JumpStart supplement prepares the body's gene expression for the transformation ahead. Meal replacement shakes replace 1–2 meals per day, and TR90 Control is taken with remaining meals to manage appetite and blood sugar.
Phase 2: Transformation (Days 31–90)
The remaining 60 days focus on sustained fat loss and lean muscle preservation. The JumpStart is discontinued; TR90 Control and meal replacement shakes continue. The body's gene expression patterns, now shifted by the JumpStart phase, support more efficient fat metabolism throughout this phase.

Frequently Asked Questions About TR90
What is TR90 by Nu Skin?
TR90 is Nu Skin's 90-day weight management system that applies ageLOC gene expression technology to body composition. It uses a combination of supplements (JumpStart, Control) and protein meal replacement shakes (GreenShake, TrimShake) to support fat loss while preserving lean muscle mass.
How does TR90 work?
TR90 targets Youth Gene Clusters (YGCs) associated with metabolism, fat storage, and muscle maintenance. The JumpStart supplement initiates a favorable shift in gene expression during the first 30 days, while TR90 Control manages appetite and blood sugar throughout the program. Protein shakes replace 1–2 meals daily to support lean muscle preservation.
How long is the TR90 program?
The full TR90 program is 90 days, structured in two phases: a 30-day JumpStart phase and a 60-day transformation phase. A 30-day starter kit is also available for those who want to try the program before committing to the full 90 days.
What is the difference between TR90 GreenShake and TrimShake?
Both are high-protein meal replacement shakes within the TR90 system. The GreenShake has a distinct green color from its plant-based ingredient blend. The TrimShake is available in chocolate and vanilla flavors. Both serve the same function — providing high-quality protein for lean muscle support as a meal replacement.
Can I use TR90 with other Nu Skin supplements?
Yes. TR90 is designed to complement the broader Nu Skin and Pharmanex ecosystem. LifePak Nano provides comprehensive micronutrient support during the program, and ageLOC Youth provides additional YGC support. Always consult your physician before starting any weight management program.
