Pre-workout supplements have become increasingly popular among gym-goers, athletes, bodybuilders, and trainers. But is pre-workout actually useful? In this comprehensive guide, we'll explore the benefits and drawbacks of pre-workout supplements, as well as the best pre-workout supplements you can buy. Pre-workout supplements are dietary formulas with several ingredients designed to increase energy and provide nutrients that help you adapt and improve sports performance over time. Most pre-workouts contain around 400 mg to 1500 mg of branched-chain amino acids (BCAAs).
However, at these levels, there is little evidence that they are effective in promoting muscle growth or reducing fatigue. Caffeine is generally added to most pre-workout supplements as a stimulant to reduce fatigue and increase alertness. Research published in the journal Food and Chemical Toxicology cites that 400 mg per day, or about two or three cups of coffee, are the maximum limits for adults. The review notes that ingestion before training appears to be relatively safe, and frequent pre-workout consumption in conjunction with a resistance training program appears to cause beneficial changes in body composition by increasing lean mass accumulation.
Some of the most common ingredients found in pre-workout supplements include creatine monohydrate, beta alanine, L-taurine, L-leucine, and caffeine. For most men, pre-training is a safe supplement to take, but even at the safe end of the spectrum, its side effects can cause nervousness, itching, and sleep interruptions, which are harmless but still uncomfortable. For those who don't want to take pre-workout supplements, a banana and a cup of coffee are a suitable and inexpensive alternative. Generally speaking, pre-workout supplements are safe to take on a regular basis if you follow the manufacturer's instructions.In conclusion, pre-workout supplements can stimulate the body's central nervous system, improve reaction time and may reduce fatigue.
However, there is no evidence that the combined use of ingredients increases performance in a way that improves your physical or health outcomes. At best, BCAAs need to be taken in much higher doses after exercise to promote muscle growth and repair.
