Athletes and gym-goers widely use pre-workout supplements to boost performance. However, most pre-workout supplements contain stimulants, such as caffeine. Alkaloid groups are called methylxanthines (e.g., theobromine and caffeine from chocolate). These ingredients are known to increase alertness, reduce fatigue, and improve performance in exercise tasks by inducing central nervous system stimulation.
Those who want to avoid stimulant pre-workout supplements can consider non-stimulant pre-workout supplements instead. Here are seven great benefits of stim-free pre-workout powder supplements you should know about:
Increased Focus and Alertness
Many non-stimulant pre-workout supplements contain B vitamins and amino acids, known for increasing focus, alertness, and concentration in users. This can help athletes and gym-goers increase mental focus and intensity during their workouts and achieve better results from their training regimens.
Pre-workout supplements that contain creatine and arginine are also known to increase alertness and focus in users. Creatine is the most widely researched pre-workout supplement ingredient. It is naturally synthesized in the liver and kidneys and found in foods like red meat and fish.
Some non-stimulant pre-workout supplements contain amino acids like beta-alanine, which has been shown to reduce fatigue and improve performance in short-term high-intensity exercise tasks. Amino acids are the building blocks of protein and are essential for the human body to build and repair cells, tissues, and organs. They are also used as dietary supplements, sports nutrition, and nutritional therapy for people with specific health conditions.
Better Muscle Endurance
Some non-stimulant pre-workout supplements contain ingredients like beta-alanine, citrulline, and taurine. These compounds improve muscle endurance and reduce muscle fatigue during exercise. They are also common ingredients in many energy drinks and coffee supplements.
Beta-alanine, often found in non-stimulant pre-workout supplements, is a naturally occurring amino acid that can increase muscle endurance and reduce user fatigue. It acts as an oxygen sensor for skeletal muscles and reduces the buildup of lactic acid, which can cause muscle fatigue.
Improved Exercise Performance
Some nonstimulant pre-workout supplements are also effective for improving exercise performance. This includes pre-workout supplements that contain high amounts of caffeine. However, most people tolerate caffeine well and experience only mild side effects. Caffeine is known to improve performance in endurance and short-term high-intensity exercise tasks by increasing the release of catecholamines. These hormones induce central nervous system stimulation and improve athletic performance.
Pre-workout supplements rich in B vitamins, creatine, and beta-alanine are also effective for improving exercise performance. B vitamins are water-soluble vitamins that are naturally synthesized in the human body. They are also found in foods like fruits, vegetables, and grains. B vitamins are essential for energy metabolism and are commonly used as dietary supplements.
Strengthened Immune System
Some pre-workout supplements contain zinc, which strengthens the immune system. This can be especially important in cold and flu season when people are more susceptible to catching infections. Zinc is also commonly found in multivitamins, which many people take as a daily health regimen. It is naturally synthesized in the liver and kidneys and found in foods like red meat and fish. Creatine is generally considered safe and is commonly used by athletes and gym-goers to improve performance in strength, power, and short-term endurance exercises.
Better Digestion and Nutrition Absorption
Pre-workout supplements that contain maca root and digestive enzymes are also effective in improving digestion and nutrient absorption. Digestive enzymes are substances produced by the human body and can also be found in food. They break down proteins, fats, and carbohydrates and make them easier to absorb and use in the body. It is also considered an adaptogen and food that can help the body adapt to stress and increase disease resistance.
A non-stimulant pre-workout supplement contains ingredients that have been shown to increase focus and alertness, reduce fatigue, and improve performance in exercise tasks by other mechanisms, such as by increasing blood flow to muscles and increasing the rate of protein synthesis. These non-stimulant pre-workout supplements can also help strengthen the immune system and improve digestion and the rate of nutrition absorption.
