ProMix Nutrition Pre-Workout Powder Mixed Berry - Focus & Endurance

In this review the ProMix Nutrition Pre-Workout Powder in Mixed Berry is evaluated for athletes and gym-goers who need a clean, focused energy lift without unnecessary additives. The bottom line: it is best for users who want clinically dosed ergogenic ingredients like beta-alanine and L-tyrosine to improve endurance and mental focus while avoiding sugar and artificial sweeteners. It mixes instantly, delivers a noticeable energy lift from green coffee extract and B12, and is designed for steady workouts rather than caffeine-driven jitters.

Key Features

• Clinically dosed ingredients: Contains 3.2 g beta-alanine, 3 g L-tyrosine and 1 g taurine per serving to support endurance and cognitive performance.
• Clean energy blend: Green coffee extract plus 250% DV of vitamin B12 supplies a natural, non-habit forming energy lift without sugar.
• No artificial anything: Formulated with monk fruit and real lemon and berry sources for flavor while avoiding stevia, xanthan gum, soy, gluten, and GMOs.
• Instant mixability: The powder dissolves quickly for convenient pre-workout prep with two scoops per serving.
• Traceable third-party testing: Each batch includes a QR code to view third-party lab results for contaminants and heavy metals.
• Sustainable sourcing: Most ingredients are North America sourced and the brand contributes 1% for the planet.

Who It's For

This pre-workout is aimed at recreational lifters, endurance athletes, and anyone who values a transparent label and clinically-studied dosages for performance ingredients. The combination of L-tyrosine for focus and beta-alanine for buffering makes it well suited to high-intensity interval sessions, strength training, and days when mental clarity is as important as physical output.

Those who prefer zero tingle or are highly caffeine-sensitive may want a milder formula, and athletes restricted from stimulant sources should check the green coffee content. It is not targeted at users who need stimulant-free or stimulant-maximized formulas beyond the green coffee extract level described.
