The Top 4 Best Fat Burner Pre-Workout Ingredients
Top 4 Best Fat Burner Pre-workout Ingredients
Pre workouts are one of the most popular supplements out there, they can have a range of functions but most aim to increase energy and fat-burning. In this article we are going to look at four of the best fat burning ingredients used in thermogenic fat burner pre workouts.
Ingredient #1. Acetyl-L-Carnitine HCL
You produce Acetyl-L-Carnitine naturally in the body via a chemical reaction between an acetyl group and L-Carnitine. This is known as ALCAR. The HCL stands for Hydrochloride and is commonly used in many supplements. Its main job in the body is to produce energy, specifically it has the ability to metabolise fat for energy. This means that stored energy (body fat) will be used to fuel your workouts, and also to fuel everyday activities.
A study by Malaguarnera et al (2007) found that L-Carnitine (which is created by Acetyl-L-Carnitine) supplementation led to decreased fat mass, increased muscle mass, and improvements in cognitive function in the elderly . Now granted the subjects were 100 years old, but the study still stands!
There is a lot of evidence that supports the belief that ALCAR can help decrease fat, and even more that it can increase energy, and improve your mental functions. Particularly if you are deficient in L-Carnitine.
Ingredient #2. Hordenine HCL
Hordenine is an alkaloid that is found in barley and other plants, it is believed to stimulate the Central Nervous System in a similar way to Caffeine, and therefore increase fat loss. Hordenine can also suppress appetite which is really useful for people who are on a diet, or a bodybuilding cut. The ingredient may also be used as a Nootropic, as it has been shown to improve cognitive function.
Studies have shown that it can increase blood pressure, meaning that if you already suffer from high blood pressure you might want to avoid it.
Ingredient #3. Synephrine HCL
Also known as “Bitter Orange” is a stimulant that works similar to (though sadly not as well as) ephedrine. Synephrine is an excellent fat-burner and may also work to suppress appetite in much the same way that Hordenine does.
Something that is quite interesting about Synephrine is that it can increase your metabolism without increasing your heart rate or blood pressure . This could potentially make it an amazing weight loss ingredient for the obese (who tend to have high blood pressure).
Ingredient #4. Caffeine Anhydrous
If your pre-workout supplement has high levels of caffeine in each serving then you can look forward to an increased metabolism and fat oxidation , improved performance in the gym , and improved cognitive function. You’ll feel more energised, you’ll increase your calories burned, and you’ll use stored fat to fuel your workouts. A pretty fantastic supplement ingredient really.
One piece of advice though, if you are using caffeine as a pre-workout try to limit caffeine outside of this. If you take too much you can build a tolerance to it. This not only negates the effects of the caffeine but can actually mess up your sleep! Not a good idea, getting a good night sleep comes with many benefits so be sure to rest well at night. It’s best to cycle caffeine, and have a couple weeks without (if you can manage this).
