What to Look For in a Caffeine Free Pre Workout?
Here are a couple of factors to consider when looking for the best non-stimulant pre-workouts:
1. Focus formula
Some of the best non-stimulant pre-workouts contain effective and powerful ingredients that help you focus. Some examples are Tyrosine and Choline. This is essential when looking for a non-stimulant pre-workout. Since stimulant-free pre-workouts do not contain caffeine, consider focus ingredients that improve your alertness.
One of the most important ingredients to consider when looking for the best caffeine-free pre-workouts is L-Citrulline. This ingredient is an amino acid that converts into arginine in the body. However, Citrulline is better absorbed than arginine, since it does a better job of increasing nitric oxide production than arginine.
So if you’re looking for non-stimulant pre-workouts, L-Citrulline should be the primary pump ingredient.
Betaine is another ingredient to consider when looking for the best stimulant-free pre-workouts. This ingredient helps you improve power and strength, making it another essential component to consider when looking for a non-stim pre-workout.
In workout terms, this ingredient is an osmolyte, which helps pull water into the muscle cells. Betaine functions as a cell volumizer in much the same way creatine does. However, these two ingredients combined can give you pumps because of an increase in the fluid inside the muscle.
When looking for stimulant-free pre-workouts, one ingredient you should consider is creatine. This ingredient happens to be the single most searched component on the planet, and for good reason. Just like betaine, creatine offers you strength, endurance, and water-based pumps. Another benefit you can get from this component is that it can fasten your recovery time.
Beta-Alanine is another great ingredient to consider when looking for the best stim-free pre-workout. Beta-alanine offers you endurance, which can get you more reps and sets. This is indirectly done by increasing carnosine levels in your body. Then, it increases your training endurance by acting as a lactic acid buffer. Not all non-stim pre-workouts have this ingredient, but the top-quality ones do.
Most pre-workout supplements contain caffeine and other stimulants, which can affect your central nervous system. Therefore, taking stim-free pre-workouts is a great alternative for individuals who are sensitive to it.
Despite containing zero caffeine, these stim-free pre-workout supplements can still offer significant benefits such as a boost of nitric oxide production, increased blood flow, and peak muscle performance.
The search for the best non-stim pre-workout can be difficult since there is a wide variety of options to choose from. So we gathered some of the best non-stimulant pre-workout supplements with pre-workout reviews for you to choose from.
We highly recommend the Pump Serum by Huge Nutrition as the best non-stimulant pre-workout for you. Pump Serum is a stim-free pre-workout that will intensify your workout performance, thanks to its combination of potent and patented components. This stimulant-free pre-workout is formulated to optimize the pump, training capacity, muscle fullness, and boost focus.
