Pre-workouts can help you to push a little more weight and allow you to keep training when you’d otherwise call it a day! And a good pre-workout contains a minimum of a few important ingredients like caffeine, Beta-Alanine, BCAAs, and L-Arginine as a base and all other ingredients are optional.

But, we’ll get into that shortly…

What Does a Pre-Workout Do?

We’re always trying to get every advantage we can when it comes to training and performance of any sort. Well, a pre-workout gives you a big boost of energy during your activities.

So, if you’re an active individual who is willing to push yourself a little, quality pre-workout ingredients will increase your heart rate, blood flow, and focus to get you hyped for that big session!

The common ingredients include:

  • Caffeine (Nervous system stimulant)
  • Beta-Alanine (Non-essential amino acid, which aids in carnosine production)
  • L-Arginine (Amino acid which converts into nitric oxide for blood vessel vasodilation)
  • BCAAs (Essential branched-chain amino acids and building blocks of protein)
  • Creatine (Helps make adenosine triphosphate (ATP) which fuels muscle energy)
  • Betaine (Beneficial for muscle growth, power and helps produce carnitine)
  • Taurine (Amino acid which provides endurance benefits)
  • L- Citrulline (Boosts nitric oxide by converting into L-Arginine)

And there are studies to shows the effectiveness for performance especially with caffeine consumption. Like one study which showed it to have a positive effect on resistance training to failure and psychophysiological factors which contribute to physical exertion.

Pre-Workout Benefits

There are some pretty obvious benefits of pre-workout supplementation.

  • More focus
  • Longer training sessions
  • Increased cardio
  • Strength and muscle gains
  • Fat loss
  • Increased blood flow
  • Better recovery

According to a study, multi-ingredient pre-workout supplements do have promise as an ergogenic aid for people who are physically active. (1)

Another study showed a pre-workout mix which includes creatine, Betaine (trimethyglycine: TMG), dendrobium extract (Dendrobex™), and caffeine to have a better effect on energy, focus and fatigue than just caffeine alone. (2)

But, all you have to do is look at user experience to know that the benefits are real.

Are Pre-Workouts Safe?

Although these products are not monitored by the FDA, most are safe for consumption by the general public. However, you must use caution before using a product which contains caffeine, and other substances which could potentially cause adverse effects.

It’s always recommended to have a full health check before using such supplements, but if you don’t, always start with the absolute lowest does possible and only buy from reputable companies which test their products.

The recommended safe daily caffeine intake amount is 400mg per day. But, people who have built up a tolerance may be able to consume more. And if you’re training, you may be able to get away with extra caffeine consumption. (3)

But it’s imperative you build up your tolerance very slowly. Taking too much caffeine at once, especially if you’re sensitive, can be very dangerous and result in health consequences.

Possible Side Effects with pre-workout ingredients:

  • Dizziness
  • Heart palpitations
  • Nausea
  • Dehydration
  • High blood pressure
  • Headaches
  • Diarrhea
