XS Pre-Workout Caffeine Content Explained
The short answer is that the XS™ Pre-Workout Boost does contain caffeine, providing a moderate dose comparable to a standard cup of coffee. The US version specifies 115mg per scoop from natural Coffea arabica powder, while international versions like the one sold in Australia list 114mg derived from guarana and green coffee bean extract. This provides a stimulant effect intended to increase alertness and jumpstart your workout. XS also includes L-Theanine, an amino acid that can work synergistically with caffeine to promote focus and energy without the common jitters associated with caffeine consumption.
Caffeine Sourcing in Different XS Products
It is important to differentiate between the various XS products. While the Pre-Workout Boost has caffeine, other products under the XS brand may have different sources or amounts, including caffeine-free options. For instance, the XS™ Energy + Focus Dietary Supplement contains 75 mg of caffeine per tablet, sourced from green tea extract. Always check the specific product label to confirm its caffeine content and source.
Full Ingredient Profile for XS™ Pre-Workout Boost
The XS™ Pre-Workout Boost formula is more than just caffeine. It’s a blend of several ingredients designed to work together to enhance different aspects of physical performance. Key ingredients include:
- CarnoSyn® Beta-alanine: This ingredient is included to buffer acid buildup in muscles during high-intensity exercise, which helps delay fatigue and increase muscular endurance. It can cause a temporary tingling sensation in some users.
- L-Citrulline: A key ingredient known to help boost nitric oxide and improve blood flow, leading to better muscle pumps and nutrient delivery during exercise.
- Amino Acid Blend: A mix of essential amino acids (EAAs) like L-Leucine, L-Valine, L-Isoleucine, and others to support muscle protein synthesis and help with muscle repair and recovery.
- Rhodiola Rosea Root Extract: An adaptogen that has been used to help the body adapt to stress and support energy levels.
- L-Theanine: An amino acid found in green tea that promotes focus and works with caffeine to provide a smooth energy boost without the jitters.
- Mega Dose of B-Vitamins: Includes vitamins like B6, B12, and Niacin to help support the body's natural energy production from food.

Is XS Pre-Workout Boost Right for You?
Deciding whether a caffeinated pre-workout is suitable for your fitness routine depends on several factors, including your fitness goals, caffeine tolerance, and potential sensitivities. The benefits of the XS Pre-Workout Boost for exercise include:
- Increased energy and focus for better workout performance.
- Supported muscle endurance through ingredients like beta-alanine.
- Improved muscular endurance and blood flow with L-citrulline.
- Balanced energy without significant jitters due to L-Theanine.
Potential Side Effects and Considerations
While most healthy adults can safely consume the caffeine content in XS pre-workout, it's wise to consider potential side effects, especially if you have a caffeine sensitivity. Some common issues include:
- Rapid heartbeat
- Headaches
- Nervousness or anxiety
- Difficulty sleeping if taken too late in the day
The beta-alanine in the formula can also cause a temporary, harmless tingling sensation called paresthesia. As with any dietary supplement, consulting a physician before use is recommended, particularly if you have pre-existing medical conditions or are taking medication.
Conclusion
In summary, yes, XS Pre-Workout Boost contains a moderate dose of natural caffeine (115mg per serving in the US version), along with a synergistic blend of other ingredients like beta-alanine, L-citrulline, and L-Theanine. This formula is designed specifically to enhance athletic performance, making it distinct from the general alertness offered by XS energy drinks. For those seeking a performance-oriented supplement, XS Pre-Workout Boost offers a balanced approach, but users should be mindful of its caffeine content, timing, and individual tolerance.
