Daily usage of Non-stim pre-workout: Understanding its mechanics and safety concerns
Non-Stimulant Pre-Workout Supplements: Boosting Performance Without the Caffeine
Non-stimulant pre-workout supplements are gaining popularity among fitness enthusiasts, particularly those who are sensitive to caffeine or prefer training in the evenings. These supplements aim to enhance performance, increase blood flow, and improve mental clarity, all without the use of caffeine or other central nervous system stimulants.
These supplements rely on a combination of ingredients to achieve their effects. For instance, L-Citrulline, L-Arginine Alpha Keto Glutarate (AAKG), and Citrulline Malate are used to boost nitric oxide synthesis. This, in turn, relaxes and widens blood vessels, increasing blood flow to muscles and enhancing the muscle "pump" during workouts [1][2][4].
Beta-Alanine is another common ingredient that increases muscle endurance and reduces fatigue through long-term usage [1][3]. Creatine Monohydrate supports energy production in muscles, improving strength and muscle endurance [1][3].
Certain non-stimulant pre-workouts also include adaptogens such as ginseng, maca root, Siberian Ginseng, and Rhodiola Rosea. These adaptogens can help reduce stress, improve focus, and balance neurotransmitters during intense training without stimulating the central nervous system [3][5]. Ingredients like L-theanine and L-tyrosine promote calm focus and sharpened mental state by supporting neurotransmitter balance and reducing jitters commonly caused by caffeine [4].
Some formulas also include vitamins, minerals, and coenzymes (such as Coenzyme Q10) to replenish essential nutrients, further supporting endurance, recovery, and mental function without stimulants [3][4].
Glycerol in pre-workout supplements increases water uptake to the muscles, contributing to the pump. Pine bark is another ingredient that contributes to the muscle pump [1].
It's important to note that while most non-stimulant pre-workout supplements are designed for daily use, they are only intended for use on training days. It's also crucial to stick to recommended serving sizes to avoid excessive intake, especially when considering other sources of these ingredients in your diet [6].
Daniel Margis, Senior R&I Scientist at ESN, explains that non-stimulant pre-workouts typically boost nitric oxide levels to improve blood flow [5]. Non-stimulant pre-workouts can provide just as much, if not more, of a muscle pump than stimulant pre-workouts [2].
Moreover, non-stimulant pre-workout supplements are generally safe to use on a daily basis. They don't elevate heart rate and alertness or pose less risk for sleep disruption, dependency, or overstimulation compared to stimulant-based pre-workouts [6].
For those seeking a non-stimulant pre-workout with the tingles, it's recommended to choose one that specifically includes beta-alanine at a clinical dose, typically around 3.2 grams [7]. However, ESN's non-stimulant 'Crank Pump Pro Pre-Workout' does not contain beta-alanine [8].
In conclusion, non-stimulant pre-workout supplements focus on increasing blood flow, muscular endurance, hydration, and mental clarity without using caffeine or other central nervous system stimulants. They offer a viable alternative for those seeking to enhance their workout performance without the side effects associated with stimulants.
