Overview

Twinlab Endurance Fuel Citrus Burst combines several ingredients known to support endurance performance and recovery. The carbohydrate blend provides varied release rates, and beta-alanine and protein components are well-regarded for their roles in athletic performance. However, the proprietary nature of the "Defense Complex" and "Endurance Blend" limits the ability to confirm optimal dosages for all included elements.

The Good

Contains beta-alanine for enhanced endurance and fatigue delay.

Includes both fast (whey) and slow (casein) digesting proteins for recovery.

The Bad

Use of proprietary blends obscure exact dosages of several key ingredients (Defense Complex, Endurance Blend, Recovery Matrix).

Contains milk and soy, which are common allergens.

Potential for mild gastrointestinal discomfort if sensitive to certain carbohydrates or milk proteins.

Is it for you?
