Bloom Nutrition High Energy Pre-Workout Review 2026: Worth the Price?
Hype Score
Bloom's High Energy Pre-Workout is a legitimately formulated pre-workout with 220mg caffeine from green tea extract, paired with L-theanine to reduce jitters. The ingredient selection is evidence-based (ginseng, rhodiola, beta-alanine, L-tyrosine all have clinical support), and the product is transparent about what it contains. However, several ingredient doses are not visible on the product page, making it impossible to verify if they're at therapeutic levels. The $39.99 price for 30 servings ($1.33/serving) is fair for a branded supplement with quality ingredients and good taste.
Bottom line: This is a solid, evidence-based pre-workout with transparent pricing and good customer reviews, but you can't verify if all ingredient doses are therapeutic without seeing the full label.
