Pre-workout Benefits and Ingredients
And any other added ingredients may be beneficial but these should be the core of an effective pre-workout supplement.
Caffeine is a nervous system stimulant.
And it’s the main ingredient responsible for the acute ergogenic effects we get from pre-workout supplements. And it’s been proven to significantly improve performance during resistance training and endurance training.
But, it’s most effective when taken in dosages of 3 and 6 mg/kg body weight. And caffeine’s effects kick in within 60 minutes of ingestion. But, an effective dose for most active people is 300mg. (1)
Creatine has been studied for many years and its effects are proven.
BCAAs, also known as Branched-Chain Amino Acids (Leucine, valine, and isoleucine) are the building blocks of protein. And they are added to many pre-workout supplements.
Nitric Oxide agents
Nitric oxide increases blood flow to muscles. Arginine and citrulline come to mind when it comes to these vasodilators which help open the blood cells so oxygen can get in. 6-8 grams per day is a minimum recommended dosage. But, high doses can be very beneficial. (1)
Beta-alanine is a precursor to carnosine which has been shown to increase high-intensity performance. So, beta-alanine is an important ingredient in a multi-ingredient pre-workout supplement. (1)
Betaine (trimethylglycine) is an effective substance which can increase nitric oxide levels and creatine synthesis. Its effects on performance have been studied and when consumed in generous doses, it can increase training volume. (1)

Warning: Do not try these supplements unless you have built up a solid tolerance to the caffeine and other potent stimulants contained in the following pre-workouts!
Jumping straight into such powerful substances can cause some serious side effects. Severe nausea, dizziness, abnormal heart rate, headaches, anxiety are among the undesirable effects with caffeine especially. (6)

Then you have a low dose of creatine to support muscle growth, increased strength, improved performance, and brain health. L-citrulline gives massive pumps while carnitine fights fatigue, and Rhodiola Rosea improves many variables of performance. Not to mention, there are a few more effective ingredients as well.
