The Just Ingredients Difference

Clean Energy

Powered by paraxanthine, a clean energy source. Paraxanthine is the primary compound your body produces when metabolizing caffeine. It works directly in the way your body already understands to support energy, mood, mental focus, and even weight management.*

Paraxanthine offers a smooth experience with fewer unwanted effects like jitters or crashes. It has a shorter half-life than caffeine, meaning it clears from the body more quickly, making it ideal for an afternoon boost, and because it’s already active, you’ll feel the benefits faster.*

Methylated B Vitamins

Vitamins B6 and B12 help support energy production by assisting in the conversion of food into cellular energy and supporting normal brain and nervous system function.* 

Using their methylated forms, methylcobalamin (B12) and pyridoxal-5’-phosphate (B6), means these nutrients are already in active forms, so your body can use them more readily without needing additional conversion.*

FAQ's

Have more questions? Let us know!

When caffeine enters your system, your body breaks it down into three main metabolites: paraxanthine, theobromine, and theophylline. Of these, paraxanthine makes up the majority and is a key contributor to the alertness and focus you feel after consuming caffeine.* Unlike caffeine itself, paraxanthine is already in its active form, so it can support focus and energy more quickly.

If you’re deciding between Yerba Mate and Paraxanthine, it comes down to the type of energy you want. Yerba Mate is a plant-based caffeine source that provides gentle, sustained energy along with antioxidants and polyphenols,* making it ideal for a balanced, traditional boost. Paraxanthine, on the other hand, is an active metabolite of caffeine that supports alertness and focus more quickly,* making it perfect for a faster-acting pick-me-up. It also has a shorter half life, so it clears from the body faster than caffeine, meaning you can enjoy it in the afternoon with less likelihood of sleep disruption.*

Paraxanthine is a stimulant, so it may affect sleep if taken too close to bedtime.* However, because it typically clears from the body faster than caffeine, some people may be able to enjoy it in the afternoon without disrupting their sleep.* It’s generally best to avoid taking it right before bed.

Paraxanthine comes from caffeine but is not technically caffeine itself. It delivers clean, focused energy, and is less likely to result in jitters or crashes.*

Yes, paraxanthine acts as a stimulant, similar to caffeine, by supporting alertness and focus.* However, because it is already the active metabolite of caffeine, it often works faster and may produce fewer unwanted side effects like jitters or crashes.*
