Been taking this supplement for a little bit now and immediately noticed the difference in energy levels and focus. It's helped my performance in the gym and gives me just the right amount of energy to get through my workouts without the crash. Great supplement!

I’ve been using trigonelline for a few months now, and it’s made a noticeable difference across the board. In the gym, I’ve seen steady improvements in strength and performance, and outside of it, I feel sharper and more focused at work. No jitters, no crash—just clean, sustained energy and better mental clarity. Definitely one of those supplements that quietly works in the background and delivers real results over time. Highly recommend giving it a try.

I noticed a difference in my energy levels especially on long landscaping days. When I’m doing physical work like digging or hauling, it helps me push through without burning out. That said, I wouldn’t take it on a rest day. It gives me more energy than I know what to do with.

I went on a 6 mile hike, first hike of the year, not expecting much. Wow. I was quite literally bouncing off the trail like a billy goat and running circles around my friends. That was day 1 taking trigonelline. I was not expecting instant results.. very impressed!

Small pill, easy to take. The promise of increased endurance with Trigonelline seemed great, but I had no expectations because it appears that many supplements promise this benefit. Anyway, I have been going to F-45 for HIIT since August 2021. Today I took two capsules (oops, the back of the bottle says only one). In short, the noticeable improvement in endurance is genuine. That was instantly recognizable. Even before the gym, as it was getting into my system, I could feel the energy without the jitters, just as advertised. It is a pleasant surprise when a product lives up to its promise!

So I get to F-45 today, and my endurance has suddenly improved, whereas previously I felt more exhausted between workout stations. I texted my wife shortly afterwards, completely impressed... I will attach the screenshot, which speaks for itself—sort of—with the voice-to-text spelling errors...

All of this to say that if you are someone who constantly pushes themselves to the limit, like me, and participates in a workout or physically demanding routine, such as high-intensity interval training, I am confident you will see a significant difference. Trigonelline appears to perform exceptionally well under heavy loads. It also appears to have other benefits, but for the time being, I recommend that you go to the gym and give it a try.
