L-theanine is an amino acid found primarily in green and black tea.
- L-Thenain can help calm you down if you're feeling really stressed or anxious.1
- It helps you focus better on simple tasks that require visual and motor skills.2
- But the best part about L-Theanine is that, in combination with caffeine, it improves cognitive performance and increases subjective alertness.3
This synergy enhance the positive aspects of caffeine while reducing its potential downsides.

Chewing has been linked to several cognitive benefits
- Chewing gum can lead to increased alertness and improvements in mood.1
- It helps to concentrate for longer periods, particularly on tasks that require continuous monitoring.2
- Chewing positively affects sustained attention, which is the ability to maintain focus on a task over an extended period.3

Epic Anvil intentionally does not include B vitamins.
You might wonder why, considering many energy products do. Here's the straight talk: unless you have a specific deficiency, adding B vitamins only serves to make your pee very, hmm, pricey. They're excreted without providing any additional benefits. We recommend checking with your healthcare provider to see if you actually need these vitamins. At Epic Anvil, we're committed to giving you functional benefits without unnecessary extras.
