Ingredients in Zuum Pre-Workout Blue Raspberry: Energy, Pump & Stamina

6g L-Citrulline DL-Malate 2:1
Faq Badge IconMood
L-Citrulline DL-Malate is a clinically studied amino acid compound that supports nitric oxide production, helping increase blood flow to working muscles during training. At a full 6,000mg dose, it’s commonly used to enhance muscle pumps, improve nutrient delivery, and reduce exercise-induced fatigue. Citrulline may also support endurance and performance output by helping clear metabolic byproducts that build up during intense training.
3g Trimethylglycine
Faq Badge IconMood
Trimethylglycine, also known as betaine anhydrous, plays a key role in cellular hydration and methylation processes that support performance and recovery. Research suggests betaine supplementation may help improve power output, strength, and training volume, while also supporting lean body composition. Its osmolyte properties help maintain proper fluid balance inside muscle cells during high-intensity exercise.
3.2g Beta-Alanine
Faq Badge IconRecovery
Beta-Alanine is a non-essential amino acid that increases muscle carnosine levels, a compound that helps buffer acid buildup during high-intensity exercise. By reducing the accumulation of hydrogen ions, beta-alanine may help delay muscular fatigue and extend endurance during demanding training sessions. The 3.2g dose used in ZUUM® is consistent with amounts shown to support improved training capacity and overall performance.
2g L-Tyrosine
Faq Badge IconRecovery
L-Tyrosine is a precursor to key neurotransmitters including dopamine, norepinephrine, and epinephrine—chemicals involved in focus, motivation, and stress response. Supplementing with L-Tyrosine may help support mental performance during physically and mentally demanding workouts, especially under stress or fatigue. This makes it a valuable addition for maintaining clarity, drive, and cognitive performance throughout training.
100mcg Vitamin B1 (Thiamin HCl)
Faq Badge IconPump
Biotin is involved in the metabolism of carbohydrates, fats, and amino acids, helping the body efficiently utilize nutrients for energy production. While commonly associated with hair and skin health, biotin also supports metabolic pathways that contribute to sustained energy during exercise and daily activity.
300mcg Vitamin B7 (Biotin)
Faq Badge IconEnergy
Biotin is involved in the metabolism of carbohydrates, fats, and amino acids, helping the body efficiently utilize nutrients for energy production. While commonly associated with hair and skin health, biotin also supports metabolic pathways that contribute to sustained energy during exercise and daily activity.
100mg Sodium (as Trisodium Citrate)
Faq Badge IconSmooth
Sodium is a key electrolyte required for proper hydration, nerve signaling, and muscle contraction. During exercise, sodium is lost through sweat, making replenishment essential for maintaining performance. Trisodium citrate also helps support acid-base balance during intense training.
50mg Astragin®
Faq Badge IconPump
Also known as "The Absorption King," Astragin® has been shown to support the absorption of certain ingredients. Supporting absorption of energizing ingredients can lend to bigger pumps and more boost in each and every scoop of ZUUM PRE-WORKOUT.†
150mg Natural Caffeine
Caffeine is one of the most researched performance ingredients, known for increasing alertness, focus, and perceived energy. Sourced from green coffee beans, this form provides a clean, reliable stimulant effect without excessive jitteriness when paired with L-Theanine. Caffeine may also support endurance, reaction time, and workout intensity.
100mg L-Theanine
L-Theanine is an amino acid commonly paired with caffeine to promote smoother energy and mental clarity. It helps balance stimulant effects by supporting calm focus and reducing overstimulation, allowing for sustained attention without the sharp spikes or crashes often associated with caffeine alone.

I have taken Zuum prior to my last 3 workouts and I love the energy, pump and stamina I'm experiencing! I took 1 scoop about 20 min prior to lifting weights and then going to Jiu Jitsu, my stamina was incredible throughout weight lifting and Jiu Jitsu training. This stuff works!

Frequently asked questions about Zuum Pre-Workout Blue Raspberry: Energy, Pump & Stamina and important things to consider when taking the product.

What's the problem with performance enhancement?

Did you know nearly half of the population drinks energy drinks more than once per week?

Here's the problem.

  • Demand for energy and work output in on the rise
  • Gym memberships are on the rise, but many are new to exercise and want to "catch up"
  • Most energy drinks contain chemicals that harm digestion
  • Most pre-workouts are packed with too much caffeine
  • The formulas of most pre-workouts are hidden behind proprietary blends
  • Taking PEDs can harm natural development and production of hormones long-term
Why do pre-workout supplements contain so much caffeine?

Pre-workout supplements are meant to enhance the workout experience - more energy, more fat loss, more muscle growth... who doesn't want that?

Pre-workout supplements usually contain a proprietary blend of ingredients. While manufacturers insist that their unique blend is responsible for the energy boost, there is invariably just one ingredient producing the buzz: caffeine.

Not surprisingly, pre-workout supplements are loaded with it. In fact, top-selling brands contain around 400mg per dose. That's the equivalent of drinking four cups of coffee.

This may not be ideal for nighttime workouts, but what's worse is - there is limited space per scoop.

More caffeine leaves less room for the other beneficial ingredients you can take pre-workout.

What should I be looking for in a pre-workout supplement?

L-Citrulline: L-Citrulline stimulates huge muscle pumps and better blood flow to your muscles and limbs.†

L-Theanine: L-Theanine smooths out the effects of caffeine, keeping you feeling calm without the jitters associated with high caffeine dosage.†

AstraGin: AstraGin has been shown to increase the absorption of L-Citrulline by up to 50%, magnifying the pump effect.†

B-Vitamins: B1 and B7 are both vital vitamins for proper metabolism function.†

Electrolytes: Electrolytes keep you going. Supplement with electrolytes pre-workout to keep your levels topped-off even during the most strenuous training sessions.†

What makes ZUUM PRE-WORKOUT so great?

First and foremost, when choosing a pre-workout supplement, it's important to steer clear of proprietary formulas.

  • Stamina: The L-Theanine x Natural Caffeine combination smooths energy over a longer period of time. Workout harder, longer and stronger.†
