ONYX® Extreme Fat Burner

ONYX® — Advanced Thermogenic Support for Women

Fat loss that works with your body — not against it.

ONYX® is BeautyFit’s most advanced thermogenic formula, created specifically for women who want real, noticeable fat-loss support without crashes, jitters, or burnout. Designed for female physiology, evolving hormones, and busy modern lives, ONYX helps your body respond better, feel better, and perform better — whether you’re balancing workouts, career, family, or all of the above.

This next-generation formula supports fat burning, elevates metabolic output, and helps target stubborn body fat while promoting appetite control, clean energy, and steady mental focus. The result is a system that helps you stay consistent, confident, and in control — instead of fighting your body every day.

Unlike harsh stimulants or one-dimensional fat burners, ONYX is built to support the whole woman. You’ll feel energized but steady. Focused but calm. Leaner without feeling depleted.
Because fat loss shouldn’t feel like punishment — it should feel empowering.

Clinical “How It Works”

ONYX combines pharmaceutical-quality, research-backed ingredients that work synergistically to support female fat metabolism, energy production, and mental performance.

Capsimax® (Capsaicinoids from Cayenne)
A clinically studied extract of red chili compounds shown to increase thermogenesis and fat utilization. Research demonstrated significantly higher free fatty acid levels before and after exercise—an indicator that the body is releasing stored fat to be used as energy. This targeted mechanism helps support metabolic output without harsh stimulation.

TeaCrine® (Theacrine Complex)
A patented compound known to support energy, motivation, and mental clarity without the tolerance build-up commonly seen with caffeine alone. Women often describe feeling “on” without feeling overstimulated.

Caffeine Anhydrous
A purified form of caffeine that supports alertness, workout performance, and metabolic activity while helping reduce perceived fatigue.

Bitter Orange Fruit Extract
Works synergistically with caffeine to support metabolic rate, energy expenditure, and healthy blood-sugar balance.

Complementary Botanicals
Aronia, olive leaf, sacred lotus, evodia, and yohimbe extracts provide multi-pathway support for metabolism, circulation, and energy dynamics — creating a comprehensive, female-focused approach rather than a single-ingredient shortcut.

Together, these ingredients encourage your body to mobilize stored fat, support steady energy, and maintain mental focus — without the harsh peaks and valleys of traditional burners.

Frequently Asked Questions
