But is it all its cracked up to be?
Find out below in our overview of the supplement’s formula, its effectiveness, and how safe its ingredients are.
How Does it Work?
Pre Jym contains a series of compounds that are designed to boost your energy, focus, and performance throughout your workouts.
Caffeine anhydrous is an effective source of energy, while other ingredients such as creatine and citrulline malate are capable of improving your performance and inducing better pumps.
If you’re looking to buy a supplement, it’s always best to opt for one which is transparently dosed.
Pre Jym fits the bill in that regard, with full dosages of all ingredients listed on the supplement facts label.
Read below as we take a closer look at each ingredient in more detail.
Caffeine Anhydrous (300 mg)
Caffeine is a staple ingredient in most pre-workouts. And for good reason – it’s scientifically-proven to provide you with an effective boost of energy.
It also happens to be the world’s most widely-used stimulant, too. It allows users to enjoy benefits such as increased power output, boosted energy levels, and improved focus 
When it comes to muscle growth, the branched-chain amino acids- leucine, isoleucine, tyrosine, and valine all play a vital role.
BCAAs also help to reduce muscle soreness after tough workouts while boosting your energy levels and focus at the same time.
A 2013 study  appeared to confirm this, with its research indicating that BCAAs help to boost exercise performance.
Creatine (2 g)
A 2012 study  discovered that this particular ingredient can improve aerobic performance, amplify the effects of resistance training, and much more.
Beta-Alanine (2 g)
Beta Alanine is contained within many pre workouts on the market, so it’s no surprise to see it included in Pre Jym.
It is a science-backed ingredient too, with a 2018 study  discovering that beta-alanine is effective in terms of increasing power output when lifting heavy weights.
Betaine Anhydrous is a common ingredient in pre-workout supplements for its workout enhancing benefits.
Research confirms that those who consume 1.25g of betaine daily can experience up to a 25% increase in strength and as much as a 20% increase in muscle mass .
Citrulline Malate (6 g)
L-Citrulline should be high up on your priority list when it comes to pre-workout ingredients.
This is because it effectively boosts your nitric oxide levels – allowing the user to benefit from incredible pumps during a workout.
However, there has been reports of mild symptoms when consuming this compound. This includes such things as stomach upset, heartburn, and changes in urination.
Taurine (1 g)
When combined with caffeine, taurine is said to positively affect human mental performance and mood .
Beet (Beta Vulgaris) Root Extract (500 mg)
Given its powerful anti-inflammatory and antioxidant benefits, it’s easy to see why this ingredient has been included in Pre Jym.
A 2011 study  also confirmed that consuming whole beetroot improves exercise performance.
Therefore, it’s clear that Beta vulgaris is a useful compound to have in a pre-workout supplement.
How to Take Pre Jym?
Within each container of Pre Jym, there is a total of 20 servings. 1 scoop is around 26g, and it is designed to be taken 30-45 minutes prior to working out.
The high dosage of caffeine (300 mg) in Pre Jym is the equivalent to around 3 cups of coffee.
So, if you’re not particularly tolerant of caffeine, you may wish to limit your intake each day, as it’s recommended that healthy adults consume 400mg or less per day .
It’s also worth mentioning that some people may experience the following symptoms if their caffeine intake is too high:
- Energy Crashes
That concludes our complete Pre Jym Pre-Workout review.
It contains several scientifically-proven ingredients including creatine and citrulline malate, but its high caffeine dosage means that it’s not suitable for those who prefer minimal caffeine intake each day.
That said, the inclusion of ingredients such as BCAAs and Beet Extract is great for those looking to enhance their workout performance and achieve better results in the gym.
