Let's bridge the gap between health and humanity

We believe in the power of the body's ability to heal the individual, and that medication and surgery should be a last resort. The products and services we provide are designed to give the body what it needs to thrive, heal and repair naturally. We do this by integrating natural health and objective, research-backed education to provide people with everything their bodies need to operate at maximum potential.

The most important step in achieving our mission is to deliver proper health and nutritional education to the public. Unfortunately, public school health education is decades behind, and medical schooling tends to avoid nutritional education in order to test the theories behind the efficacy of pharmaceuticals in isolation.

We choose our products carefully and research them thoroughly before releasing to the public. If you choose not to start your health journey with UMZU, we still encourage you to browse the educational pieces below. The more you understand about your body, the better you will be able to take control of your own health.

The Problem with Performance Enhancement
Did you know nearly half of the population drinks energy drinks more than once per week?

And 12% of high school boys take some form of performance-enhancing drugs (PEDs)?

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 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.

Let's take a look at these...
What to Look for in a Pre-Workout Supplement
OTHER PRE-WORKOUT INGREDIENTS THAT WORK
- 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.

Tuco Salamanca would LOVE this stuff!!!

And love this stuff too!I've used this for a week's worth of workouts so far.First off, the taste is great! I got the Tiger's Blood flavor. Second, it has consistently provided me with a serious boost of super smooth energy...seriously, almost like a supercharged zen feeling energy. Third, the pump was great. I combined it with UMZU's Redwood which definitely kicks up another notch!Fourth, there is absolutely no crash afterwards...smoothest landing ever. To sum it up, ZUUM is hands-down the BEST pre-workout I've ever used.

Great flow of smooth energy

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!

- Jake N., Verified Buyer

Amazing Product

This product is phenomenal and has exceeded my expectations. You don't feel jittery but rather uplifted and amped. The ingredients allow you to get a sustainable high intensity workout without any type of burnout, that you would typically get from other pre workouts. This is a true game-changer and is allowed me to reach new levels in the gym and I'm not exaggerating this in the slightest bit
