Ingredients with Integrity

At PUFs, we are reimagining energy and how we consume it.

PUFs are formulated with green tea caffeine. Green tea contains a magical combination of caffeine and l-theanine:

What is l-theanine?

L-theanine is a naturally derived amino acid found in green tea that helps counteract the negative effects of stress and anxiety on the mind while also enhancing brain function and focus to give you a feeling of calm alertness².

How does l-theanine work?

L-theanine interacts with neurotransmitters in the brain, such as dopamine and serotonin, to provide anxiety-reducing and calming effects while keeping you focused.

In the brain, l-theanine stimulates production of alpha waves, a type of brain wave that creates a deep, relaxed state in the mind while also keeping you mentally alert, similar to how you feel after meditation¹. Activity in the alpha frequency band also increases after l-theanine consumption, helping relax the mind without inducing drowsiness².

How do caffeine and l-theanine work together?

The combination of caffeine and l-theanine is magical, as the calming effects of l-theanine counterbalances some of the negative excitatory central nervous system effects of caffeine. When consumed standalone, caffeine causes blood vessel constriction, otherwise known as vasoconstriction, which results in elevated blood pressure, rapid heartbeats, headaches, and other effects similar to how you feel during times of stress.

In a study that combined caffeine with l-theanine, results showed that l-theanine lessens vasoconstriction³, so you’re less likely to feel the faster heartbeats, blood pressure spike, and anxious, jittery feeling.

In another study, the combination of caffeine and l-theanine suggested that the two together can help improve performance for cognitively demanding tasks⁴. Test subjects reported fewer headaches (goodbye caffeine headache!) and less tiredness overall when caffeine and l-theanine were combined compared to consuming just caffeine on its own⁴.

What else is in PUFs?

In addition to green tea caffeine, PUFs snacks are made with all recognizable, high quality ingredients to help power you through your day. Our honest ingredients include almond flour, coconut sugar, vegan chocolate chips, coconut oil, flaxseed, and coconut flour.

Nothing weird, nothing fake. So you can feel good knowing you’re putting good food into your body.

Pretty magical, huh?
