5 Reasons Why Advanced Pre-Workout Will Optimize Your Performance

Have you been looking for a way to optimize your daily workouts?
Athletes, and active individuals in general, commonly use a pre-workout supplement to boost performance with caffeine for energy, a handful of amino acids, and other ingredients for focus and strength output.
Thorne Advanced Pre-Workout goes beyond the basics. We scientifically formulated Advanced Pre-Workout to promote blood flow, delay the time to fatigue, enhance focus, and give you a greater pump.*
So what makes Thorne Advanced Pre-Workout different from others? Let’s find out:
1. Clinically relevant dosing
Advanced Pre-Workout contains clinically relevant doses of alpha-GPC, beta-alanine, L-citrulline, caffeine, and L-theanine to help you see noticeable benefits in your performance.* Let’s check out what those doses are, and what they do:
- 600 mg of alpha-GPC, which is a choline-containing compound found in the brain that can support the body’s production of the neurotransmitter acetylcholine. An increased amount of acetylcholine can promote focus during your workouts, effectively enhancing the mind-muscle connection. Additionally, it can help to enhance power output and promote physical endurance.*
- 3.2 g of beta-alanine, which is an amino acid that supports the body’s carnosine levels, which can efficiently buffer the pH of muscle tissues, preventing excessive lactic acid buildup and increasing perceived time to exhaustion.*
- 5 g of L-citrulline that’s another amino acid, but this one supports the synthesis of nitric oxide, promoting blood flow to working muscles and leading to a greater “pump.”*
- 200 mg of caffeine provides a stimulant that can enhance athletic performance, especially when consumed before activity by reducing perceived effort.* The caffeine in Advanced Pre-Workout is naturally derived from coffee beans.
- 200 mg of L-theanine – an amino acid found in the tea plant – can enhance neurotransmitters associated with mood, focus, and memory. Having L-theanine in a pre-workout can enhance performance and accuracy when combined with caffeine, as well as limit the jitters normally associated with increased caffeine intake.*
2. No Harsh Crash
Advanced Pre-Workout is formulated to help you see noticeable benefits in your performance, but we don’t want you to crash after your workout because of high amounts of caffeine and sugar, without anything to balance it.
First, Advanced Pre-Workout is made with 0 g added sugar and no artificial sweeteners. Second, our formula contains L-theanine, which has been shown in research to balance the effects of caffeine, creating a focused and alert, yet calm state of mind.*
3. Label transparency
With many pre-workout supplements, you may notice two words on the supplement facts label: “proprietary blend.” A proprietary blend is a mixture of ingredients found in a dietary supplement, where the manufacturer lists the ingredients in the “blend,” but does not reveal the precise dosage of each ingredient. This comes back to Advanced Pre-Workout, which contains science-backed doses of ingredients that are listed on the supplement facts label for full transparency, so you know exactly what is in the product and you can trust that it’s working.
When a Thorne product is NSF Certified for Sport®, it means it has been third-party tested to be free of nearly 300 substances banned by major athletic organizations. For a supplement to bear the NSF Certified for Sport® mark, it must undergo a three-step process, including being manufactured at a GMP-registered facility, annual verification of the supplement’s formula by NSF, and lot-by-lot testing of every batch of that supplement for final certification of each bottle.
That’s right: The final step – which confirms that the product is free from nearly 300 substances banned by major athletic organizations – must be performed on every batch from the time of certification on.
Typically, you will find that common pre-workout supplements are not NSF Certified for Sport®, meaning that they haven’t gone through these three stages of rigorous independent testing and third-party certification. Advanced Pre-Workout provides peace of mind, knowing you can trust the quality and safety of every batch.
