The number of young adults who use energy drinks has been constantly rising year after year [1]. Students use them for all-nighters, athletes use them to get an edge over their opponent, and gamers drink them to heighten their split-second reflexes. Energy drinks seemingly can make the impossible possible. But are energy drinks truly capable of all that or is it just really good marketing. If you take a look at the nutritional facts panel of the leading energy drink brand you can see that beyond some B vitamins, all energy drinks are essentially carbonated caffeine and taurine water with a chemical aftertaste.

Soylent decided to take up that challenge to create our own energy drink and it’s called Stacked.

Soylent vs Leading Energy Drink Brand

We compared Soylent Stacked to the leading energy drink on the market. We put the two products’ ingredients side by side to see how Soylent Stacked compares.

Soylent Stacked can push you beyond your limits

Soylent Stacked is built on the foundation of a nootropic stack whereby ingredients are combined together to provide better cognitive support than any single ingredient could. Soylent Stacked contains caffeine which provides energy, boosts focus and increases brain activity by stimulating the production of glutamate. Glutamate is an excitatory neurotransmitter which sends signals throughout the nervous system. The increased presence of these neurotransmitters from caffeine boosts overall brain processes however one of the side effects of caffeine is that it sometimes induces anxiety in the process [2]. As a result, L-theanine is paired with caffeine in Soylent Stacked to counteract the anxiety potentially induced from caffeine [3]. This is important as Soylent Stacked contains more caffeine than the leading energy drink (Stacked 100mg vs Leading Brand 80g). L-Tyrosine is another amino acid which has shown to increase dopamine levels in the brain and was added since its been shown to promote cognitive flexibility which ultimately improves task switching [4]. Lastly, Soylent Stacked contains Alpha-glycerylphosphorylcholine (Alpha-GPC). Alpha-GPC is a bioavailable form of choline that is metabolized to acetylcholine, a neurotransmitter. During exercise and other stressful activities, choline runs low because our body is using it up as acetylcholine and this can lead to our peak physical and mental performance to be affected [5, 6]. People who consume more choline have shown to have better verbal and visual memory hence it is an ideal ingredient for our nootropic stack [7]…
