Pre Jym Pre Workout Ingredients & Benefits

It has 13 hand-picked ingredients:

  • Creatine: It improves muscle power and performance during a workout. Some people want it to be in their pre-workout and some don’t. The reason is obvious that creatine causes water retention which makes it difficult to achieve a lean physique especially for those who are preparing for a contest. It contains 2 grams of creatine, which is a pretty decent amount.
  • Beta-Alanine: It contains 2 grams of beta-alanine, which may help to improve endurance during a workout. It is also responsible for causing that unusual tingling sensation over your skin.
  • Betaine: It is used in a pre-workout supplement to improve your power output during workouts [1].
  • Taurine: It is a non-essential amino acid naturally produced in the body, which may help to improve your performance in the gym by reducing fatigue. It also reduces the jitteriness usually associated with a big hit of caffeine.
  • N-Acetyl L-Cysteine: It is a substance derived from an amino acid L-Cysteine. It is an antioxidant that may reduce the damage of the cells.
  • Alpha-Glyceryl Phosphoryl Choline (Alpha GPC): Like betaine, Alpha GPC may help to enhance the power output in athletes.
  • Citrulline Malate: It is an amino acid, which may boost Nitric Oxide in the body that will increase the blood flow in the muscles. More blood flow will improve endurance and also provides a better muscle pump. It contains 6 grams of citrulline which is exactly the recommended dosage of it [2] [3].
  • Beet Root Extract: It is a root vegetable commonly used in many cuisines around the world. Various studies have suggested that it boost nitric oxide production, which would improve your endurance.
  • Branched-chain amino acid: There are only a few pre-workouts that contains Branched-chain amino acid (BCAA) and it is one of them. The BCAA consist of three amino acids –  L-Leucine, L-Isoleucine and L-Valine. It may improve your muscle growth and endurance and reduce fatigue.
  • Caffeine Anhydrous: It has 300 milligrams of caffeine which is relatively a high amount as most of the pre-workout contains around 200 milligrams of caffeine. Just for a comparison, you will find this much of caffeine in 3 cups of coffee. Caffeine improves athletic performance by keeping you stay alert and focused during a workout and it also reduces fatigue.
  • Huperzine A Extract: It is a substance extracted from a plant and is used in a pre-workout supplement to enhance your memory and learning power, but it lacks sufficient scientific researches.
  • Black Pepper Fruit Extract: It has been shown that black pepper extract may help to increase oral absorption of various ingredients present in a pre-workout supplement.

Other Ingredients: There are other ingredients in this pre-workout, which are mostly there to enhance the taste of the supplement and to protect it from sticking together.

Pre Jym Pre Workout Side Effects

The first thing you should notice in a pre-workout is its ingredients and make sure that you are not allergic to any of these ingredients. If you find any ingredient that you are allergic to, I would recommend not buying it.

The possible side effects of a pre-workout are tingling sensation, jitters, insomnia, upset stomach, diarrhea and rapid heartbeat.

The amount of caffeine in this pre-workout is 300 milligrams, which is too much for some people especially for beginners. However, there are few people who consume more than 400 milligrams of caffeine and still they don’t experience any side effects because they are tolerant to that much caffeine.

This pre-workout has ingredients which help in minimizing these side effects like taurine. You hardly face any side effects except a tingling sensation over your skin if you consume it as per the directions given on this pre-workout. I’ve explained below how to take it to minimize the effects.

Pre Jym Pre Workout Flavor

Currently, Pre Jym pre-workout comes in the following flavors:

  • Cherry Limeade
  • Orange Mango
  • Pineapple Strawberry
  • Rainbow Sherbet
  • Raspberry Lemonade
  • Strawberry Kiwi
  • Tangerine
  • Natural island Punch

Pre Jym Pre Workout Price

The 30 servings container would cost you around $39.

So, per serving would cost around $1.3, which is slightly on the expensive side since most of the pre-workouts per serving would cost between 60 cents to $1.

How To take it

Mix one scoop of Pre Jym with 16-24 oz of cold water and drink it 30-45 minutes before workouts. Initially, use half serving or less to assess tolerance and once tolerance is assessed, take no more than one serving.

If you are a beginner or someone who is sensitive to caffeine, try to start it with only a half serving for few days to assess the tolerance and if you are having a hard time consuming it, stop taking it immediately.

If you are tolerant to this much caffeine, you can start with one serving directly, but not more than that.

Do not take this pre-workout within 6 hours of bedtime to avoid sleeplessness or insomnia.
