Types of Caffeine Free Pre Workout Supplements

Sample of Caffeine-free supplements for workout

There are several main types of caffeine free pre workout products. But, how do they work? If they are truly stimulant free pre workout products, then they’ll also be caffeine free. Because caffeine is one of the most popular and effective energy boosters available, it’s often a key ingredient in pre workout products. However, many people don’t like the jitters and other side effects caused by caffeine. Is it possible to get the energy boost without caffeine? There are several popular non stimulant pre workout supplements. Learn about the main categories below:

  • Nitric Oxide Boosters

Nitric Oxide is a naturally occurring gas. In the human body, it affects a number of areas including the cardiovascular system. As far as boosting your workout goes, nitric oxide supplements may help by increasing your blood flow.

Nitric oxide supplements aren’t actually nitric oxide, but usually contain ingredients that can help your body naturally produce more of the nitric oxide. Citrulline and other amino acids may play a role in increasing your nitric oxide levels. Citrulline in particular has been associated with improved athletic performance and lower levels of soreness after exercising. These two studies were done based on performance while cycling and weightlifting, suggesting that this sort of supplement works for cardio and weightlifting exercise alike.  L-arginine, nitrates and beetroot are other ingredients that may be used in itric oxide supplements.

  • Protein Mixes

Other popular stimulant free pre workout supplements include mixes of proteins or amino acids. Some of the most popular ingredients in these protein mixes include creatine and beta-alanine which are known for their workout enhancing effects. Creatine in particular is a favorite for those looking for a muscle building supplement, but can also help you increase your strength and power in a workout. Beta-alanines are also known as exercise performance enhancers.

List of Stimulants (Avoid These Ingredients!)

Man thoughtfully reading the ingredients of the supplementsWhen shopping for the best caffeine free pre workout supplement, you’ll likely run into a lot of new ingredients you’ve never heard of before.  What should you be on the lookout for to avoid? With this list of stimulants in hand, you can double check products to ensure that they don’t contain stimulants. Remember, stimulants may be disguised even in natural products. So, don’t forget to check the ingredients for items on this list of stimulants. Otherwise, you may receive an unpleasant surprise of the jitters upon trying the supplement.

  • Caffeine: coffee, cocoa, kola nut, tea, guarana, xanthine, yerba mate, methylxanthine
  • Beta-­Methylphenethylamine: acacia rigidula, alpha-benzylethylamine, 2-phenylpropylamine
  • Dimethylamylamine: DMAA, geranium extract, forthan, pentylamine, floradrene, metexaminimum
  • Dimethylbutylamine: amperall, methylpentane, pentergy, 4-AM
  • Ephedra
  • Citrus Aurantium (bitter orange)
  • Higenamine
  • Hordenine (1)

While the ingredients listed in italics are now illegal due to dangerous side effects, many others, like caffeine, are not. Many stimulants are perfectly safe to use as long as you don’t have a sensitivity to them. However, that doesn’t mean you can use legal stimulants without risk. For example, caffeine, while usually safe, when taken in excess can interfere with your cardiovascular system and lead to an increased or irregular heart rate, insomnia, and worse. If you do choose to use a caffeinated pre workout supplement, you should be careful to note the amount of caffeine you’re ingesting in your daily diet. Remember, if you also drink coffee or soda or eat chocolate, you’ll just add to your daily caffeine intake.

You can avoid illegal ingredients by purchasing from reputable companies that have their GMP certification (which means they fulfill certain requirements set out by the FDA). In addition, always double check ingredient lists and avoid any of the above-listed ingredients.
