Caffeine is one of the most effective substances for increasing energy and promoting focus and concentration. These reasons are why caffeine has been used in many of the typical pre-workout supplements. On the other hand, caffeine is also an addictive substance with some significant side effects. Therefore, it would be very helpful if there were an alternative that might be just as effective without the resulting side effects. Here are the
Sulbutiamine is a nootropic that has many excellent benefits. It is designed to help improve your mood, memory, and energy levels. Additionally, there is no resulting crash and you will feel more alive after taking this supplement. The increased focus and endurance is caused by the supplement raising levels of thiamine and thiamine-phosphate esters within the brain. This is now becoming a popular addition to energy drinks with several studies showing significant increases in focus and reaction time performances.
Citrulline malate is an amino-acid formulation that helps provide energy directly to the muscles. Otherwise known as intramuscular ATP, this fuel is exactly where you want your pre-workout energy boost to go—right to the working muscles. The more ATP you have, the longer your muscles will function at an optimal level. Not only will you benefit from an increased amount of working muscle energy, but you will also see an improvement in endurance and recovery times.
Beta-Alanine is another caffeine alternative to consider adding to your pre-workout stack. This is actually less of an energy enhancer and more of an endurance provider. In the end, it accomplishes pretty much the same thing but the method of action is interestingly different. This supplement works by increasing intramuscular-carnosine levels. Carnosine is a substance that helps to remove lactic acid from your muscles. Lactic acid is what results from working a muscle (too much lactic acid and not enough ATP means that muscle becomes sore and will not perform at an optimal level). This would be a great supplement to stack together with a pure caffeine-replacement energy enhancer (Citrulline Malate, for example).
