What is Caffeine?

Caffeine is a natural stimulant commonly found in coffee, tea, and other plant-based sources. It is usually extracted through water or solvent extraction processes from these natural sources, or it can be synthesized in a laboratory.

Caffeine is mainly used to enhance alertness, improve concentration, and reduce the perception of fatigue. It works by blocking adenosine receptors in the brain. Most studies show that moderate caffeine intake is generally safe and can offer benefits like increased cognitive performance and reduced risk of certain neurodegenerative diseases, though excessive consumption might cause jitteriness, insomnia, or increased heart rate.

When you see caffeine on a label, it indicates an added boost of energy, typically in beverages or supplements. Keep an eye on total consumption to avoid potential negative effects associated with high doses.

120mg per can is a moderate dose. However, no source is specified — no organic, green coffee, or plant-derived claim — suggesting synthetic caffeine anhydrous rather than plant-derived.
