The Best Low Caffeine Pre-Workouts
Transparent Labs Stim-Free Pre-Workout
? Best pre-workout with no caffeine
Caffeine content: 0mg per serving
The Transparent Labs Stim-Free Pre-Workout is the best overall low caffeine pre-workout thanks to its combination of clinically-backed ingredients, excellent taste, and excellent manufacturing process.
It stands out from other low caffeine pre-workouts because it has zero caffeine or stimulants, making it a superior choice for workouts without the jitters and crashes typical of traditional pre-workouts.
The key performance-boosting ingredients in each serving of Transparent Labs Stim-Free include:
Citrulline malate (6,000mg) – Citrulline malate is a natural compound that acts as a nitric oxide booster, increasing blood flow to active muscle, improving exercise performance, and improving muscle recovery (Gough et al., 2021).
Beta-alanine (4,000mg) – An amino acid, beta-alanine helps you to workout longer and delays muscle fatigue. A paper titled “The Effect of β-Alanine Supplementation on Performance, Cognitive Function and Resiliency in Soldiers” showed significantly improved athletic performance (Ostfield and Hoffman, 2023).
BCAAs (4,000mg) – Branched-chain amino acids are a collection of three amino acids that help you workout longer, increase muscle synthesis (Holecek, 2018), burn more fat (Mourier et al., 1997), and even act to reduce muscle soreness (VanDusseldrop et al., 2018).

BetaPure Betaine Anhydrous (2,500mg) – Betaine is an organic compound found in many foods. It’s been studied extensively as a supplement, with multiple studies showing that it increased hypertrophy and power output in well-trained men over just 6 weeks of use (Cholewa et al., 2013).
Taurine (1,300mg) – Taurine is an amino acid found in skeletal muscle. It also plays a significant role as an anti-inflammatory and antioxidant. Research has found it to be effective at improving exercise performance, reducing muscle soreness and improving strength and endurance (Kurtz et al., 2021).
L-Tyrosine (1,000mg) – L-Tyrosine is yet another amino acid that mimics the focus and cognitive benefits of caffeine. One study published in the European Journal of Applied Physiology with elite soccer players found tyrosine had positive impacts on reaction time and cognitive function (Coull et al., 2015).
Beyond the long list of clinically studied ingredients that improve workout performance, the Transparent Labs Stim-Free Pre-Workout is also manufactured at the highest possible standard.
Transparent Labs, as you can probably guess by the name, manufactures the Stim-Free in a GMP and FDA-certified facility and has all of their supplements tested by third-party organizations to assure purity.

While the price point on the Six Star Explosion is hard to beat, there are a couple of things I didn’t love about this pre-workout.

All that said, the Six Star Explosion is a cost-effective low caffeine pre-workout for people who want a bit of a buzz before their workouts.
How to Choose the Best Low Caffeine Pre-Workout
The world of supplements can feel overwhelming for newbies. But once you understand a few key things, choosing between the low caffeine pre-workouts gets easier.
Here are the key things to look for when shopping around for the right low caffeine pre-workout for you and your goals:
Caffeine content – Naturally, the first thing to look for is the caffeine content of the pre-workout. Typical pre-workouts have between 150-250mg of caffeine, with some?high-stim pre-workouts have 350-400mg of caffeine.
Low caffeine vs. No caffeine – When choosing a pre-workout, consider whether you want a low or no caffeine pre-workout (also known as?stim-free pre-workouts). Stim-free pre-workouts are widely used and can be the perfect pre-workout for caffeine-averse gymgoers.
Stimulants – Caffeine isn’t the only stimulant used in pre-workouts. Theobromine, synephrine, and hordenine are other forms of stims. These tend to be milder compared to caffeine and help to improve focus and reduce fatigue.
Ingredient List – Check the ingredient list for performance-enhancing ingredients like beta-alanine, tyrosine, BCAAs, Citrulline malate, and other natural compounds. Be weary of supplement brands that rely heavily on proprietary blends which can mask hidden ingredients.
Artificial flavors and sweeteners – Supplements utilize natural and artificial sweeteners to increase palatability. Artificial sweeteners like sucralose and aspartame can be difficult to digest for some users. Look for naturally-sourced sweeteners like Stevia.
Third-party testing – Third-party testing ensures that the low caffeine pre-workout you buy is pure. Supplement companies—often fairly—have earned a rep for not always being honest about what’s on the label. Third-party testing means you are ingesting what is on the ingredient label and nothing else.
Taste and Flavor – While the flavoring isn’t the most important thing to consider, a low caffeine pre-workout that tastes good goes down easier and makes for a more enjoyable supplementing experience. Check out reviews and try samples at your local supplement store to get a sense of the taste.
Cost – Supplements can get pricey when you add up the months and years of supplementation. Look to drive down the cost-per-serving by considering a subscription (saving up to 10%) to the preferred low caffeine pre-workout of your choice.
