Synthetic caffeine, like those found in most sodas and energy drinks, are produced in laboratories and absorb through the digestive system much faster than the naturally occurring plant caffeine. This means a quicker spike, and of course, a quicker crash—unlike the naturally occurring caffeine in plants such as green coffee beans which provides a balanced caffeine ‘lift’ (largely due to also present high level of naturally occurring vitamins that prevent the caffeine crash). While this natural source of caffeine provides energy, a number of studies also report that it helps boost the metabolism anywhere from 3 to 11 percent [1]. In fact, caffeine is actually one of only a very few natural compounds that have been scientifically proven to aid fat burning [2].

A number of studies have shown that this amino acid has the power to increase NO (nitric oxide) production [3]. More NO, you may have heard, means increased blood flow to muscles during exercise, which allows them to last longer under duress—and produce bigger muscle pumps [4], [5]. L-Citrulline Malate is also known for having fatigue-fighting capabilities by helping the body recycle lactic acid and use it for energy [6].

The benefits of working out with beta-alanine are backed by major university and peer-reviewed studies for it’s proven results in increasing lean muscle mass as well as reducing feelings of fatigue during exercise [7], [8]. This non-essential amino acid has also been shown to boost muscular endurance and increase one’s exercise capacity so that you can train harder, for longer [9], [10].
