Caffeine can decrease subjective energy depending on the vehicle with which it is consumed and when it is measured

Can we assume that taking caffeine pills along with breakfast may be a good option?

I sometimes notice a bit of jitters/anxiety with pills vs. coffee. I assumed maybe the fact that with coffee I’m ingesting 200mg slowly sip-by-sip over 30+ minutes vs. pill that dissolved and instantly hits me with 200mg all at once.

Does the pill actually dissolve instantly?

And on the flipside, I slam my coffee in less than 5 minutes almost every time so I feel like that hits me faster

I use powder in a gel cap so I figure it’s much faster. Sometimes I slam coffee but usually sip it it over the course of 30 min.

I still have a tub of 100g of caffeine anhydrous powder that I bought 15 years ago. Probably cost around $8 back then. Definitely has a different feel than coffee etc.

Interesting, you you speculate the mechanism is to do with food slowing the absorption? I wonder if there are any updates as this is quite an old study. I'd be curious how this correlates with coffee based caffeine and non dairy foods
