   As a full-time student juggling work and daily gym sessions, I need an energy boost that won’t leave me crashing and Vital Bloom Lab’s Paraxanthine Capsules have been a game-changer! Unlike caffeine, which usually gives me the jitters, this has been the ONLY supplement that has thus far provided me with clean, consistent energy that lasts throughout my packed days. Whether I’m powering through work, school, or intense workouts, I feel sharp, alert, and energized without the usual side effects. As a woman constantly on the go, finding a supplement that keeps up with my lifestyle is a win, and I’m beyond impressed with how well this works! Totally worth it, this gives me the endurance I need!!!

   As someone who was weening myself off of caffeine, I was looking for an alternative with less negative side effects. I happened upon Paraxanthine via some nootropic video recommendation on YouTube. After purchasing this product, I didn’t know if it would work or not. In case it did, I paired it with Suntheanine® and Lithium Orotate. I experienced an increased sense of awareness and awakeness. One that carried on into my restful hours. Took a while to fall asleep, and woke up several times during the night. Paraxanthine may be easier on thee adrenals, but it’s intense on the wakefulness. I’d recommend it only be taken in the early morning, and for those whose occupations require intense focus. Especially truck drivers going long distances. I’d caution against taking more than 1, 200mg capsule per day.

   This has been great. Waited over a week to post any results. The first day was definitely a jolt, but by day 2 and 3 things leveled out. My appetite has been relatively low and my energy has been quite high. In terms of cognitive, I work in engineering and in the last 10 days I have completed far more tasks than I have without it because I have been able to really buckle down and concentrate. I have a very complex job and have been operating at the same speed I did 20+ years ago. So yes, yes I would recommend this to anyone who hasn’t been feeling their max levels in awhile. Mood has been great too!

   I don’t usually write reviews, but I had to share my experience with this supplement because the results have been amazing. I was skeptical at first — like most people, I’ve tried plenty of products that made big promises but didn’t deliver. This one, however, actually worked.

   Within the first week, I noticed a boost in my energy levels and improved focus throughout the day. I didn’t feel jittery or wired, just naturally more alert and motivated. I also started seeing physical results: reduced bloating, better digestion, and I even dropped a few stubborn pounds without changing much else in my routine.

   What I really appreciate is that there were no negative side effects for me, no headaches, no nausea, and definitely no crashes. The ingredients list is clean, and you can tell the company put thought into the formulation.

   I plan to keep this in my daily routine and ff you’re on the fence, I highly recommend giving it a try — it made a huge difference for me!

   Surprisingly Potent

   I was surprised to find this had no effect after reading all the positive reviews. I have tried 200mg, 400mg and 600mg doses with no effect at all.

   Giving 2 stars because the packaging and company seem to be good, but the product was worthless for me.

   It’s possible I just don’t respond to this supplement,

   I’m typically skeptical when it comes to trying new supplements. As a law student and a habitual coffee drinker, I never thought I’d be able to give up my daily cups of coffee. But after taking paraxanthine consistently for two weeks, I can confidently say I’m pleasantly surprised at how well this stuff works.

   I don’t like the jittery feeling I get from coffee, and this has been a perfect alternative. It gives me clean, focused energy without the crash, and I feel sharper — especially during long study sessions. I honestly didn’t think I could go without coffee, but I haven’t had the urge to go back since starting this. It’s been that effective. Definitely buying again!

   I was honestly skeptical at first, but this supplement blew me away. The energy boost is incredible—clean, focused, and without any of the jittery side effects I usually get from coffee. I feel alert, productive, and steady for hours. No crash, no anxiety—just smooth energy that keeps me going. It’s like caffeine evolved. I’ve officially swapped my morning coffee for this, and I don’t miss it one bit. Highly recommend if you’re looking for a better, more consistent way to power through your day.
