Zantrex-3 Black
Zoller Laboratories
Overview
Zantrex-3 Black is a weight loss supplement that combines multiple stimulants and herbal extracts. While some ingredients, such as caffeine and niacin, have demonstrated certain benefits, the product relies on a proprietary blend, which obscures the individual dosages and overall effectiveness. The lack of transparency and limited clinical evidence specifically on this formulation makes it difficult to ascertain its true efficacy.
The Good
Contains Niacin: Provides 150% of the daily value for Niacin, which supports energy metabolism.
Includes Black Pepper Extract: May enhance the absorption of other ingredients.
Energy Boost: The combination of caffeine, Yerba Mate, and Guarana may provide a noticeable energy boost for some users.
The Bad
High Stimulant Content: Contains approximately 300mg of xanthines (caffeine and caffeine-like stimulants) per serving, which may cause nervousness, irritability, sleeplessness, and rapid heartbeat in sensitive individuals.
Proprietary Blend: The Zantrex blend prevents knowing the exact dosage of each ingredient, hindering assessment of individual ingredient efficacy and potential interactions.
Potential Drug Interactions: Contains ingredients like black pepper extract that may affect the metabolism of certain medications.
Is it for you?
Best For: Individuals seeking a strong energy boost, short-term weight management support
