Daily caffeine intake

6 months ago (edited)

Do you use caffeine regularly — and if so, how much, in what form, and at what time of day? Whether it’s coffee, green tea, matcha or something else, each source hits differently.

Some people even cycle on and off to avoid dependency or limit it to certain time windows.

Curious how you personally use caffeine and what role it plays in your daily routine?

I’m trying to avoid caffeine for the first hour after waking up and stop drinking caffeinated coffee after 12 p.m. to avoid disrupting my sleep.

After noon, I switch to decaf.

I’ve also read studies about mycotoxins and mold in coffee, which is why I’m selective and usually go for organic, third-party lab-tested brands such as

Would love to hear more caffeine routines:

I drink 2-3 cups of coffee in the morning and stop after 1pm to reduce any impact on my sleep. But I am not dogmatic about it. Occasionally I will drink a coffee in the afternoon as well.

As I am a fast metabolizer, so this works perfectly for me.

When I first tried a classic week of fasting (only water) many years ago, I got raging headaches on day 2 or 3 ... It couldn't have been from alcohol, and I could rule out a lack of minerals. When I couldn't take it anymore, I sipped a cup of espresso and the headaches immediately disappeared! I found that crazy!

Since then, I have been trying (with varying degrees of success) to reduce my coffee consumption.

Currently, I am doing well with two small cups in the morning and one small cup after lunch. I rarely, if ever, drink coffee after 2 p.m.

And being a fast metabolizer, too, I am also not too dogmatic with that rule.

I usually drink 2 espressos a day. One at breakfast and the other after lunch (2 p.m.).

I'm trying to drink a matcha latte at breakfast rather than one espresso, and I feel better. It seems that I feel more energetic for longer, but without dragging myself around afterwards.

I never drink coffee after 5 p.m. (even decaffeinated) because it makes me feel nauseous.

I switch between coffee and matcha depending on what kind of energy I need.

Coffee wakes me up fast but sometimes makes me feel a bit anxious or jittery.

Matcha on the other hand gives me a calm and clear focus, more balanced and longer lasting.

I like having both options. Some days I want that fast kick, others I prefer the long lasting zen mode.

I don't drink coffee and I hardly drink tea. Some tea bags might contain plastic. And according to my dna,

I should avoid sulfation inhibitors. It says no chocolate, flavonoids, piperine, black/green tea, and citrus fruits!

Moved from coffee to green/black tea a while ago. Helps me stay focused for longer and without the "caffeine crash" - and my gut is happy about the switch as well ;-)

If you stick to coffee and experience those crashes or also jittery or anxious feeling as described by others, maybe try combining it with L-Theanine. Really interesting compound found in many teas. Studies show that it can improve the effect of caffeine quite a bit.

One recent study:  Nawarathna et al. (2025) "High-dose L-theanine-caffeine combination improves neurobehavioural and neurophysiological measures [...]"

I like to start my day of with Gyokuro or a sencha-matcha blend, 500-750ml. It doesn't impact my blood sugar or cortisol (which pre-food caffeine can in some individuals), so I am fine with drinking it about 30-45min after waking.

I might have a matcha in the afternoon, depending on whether I feel like it.

As for coffee: I usually have my filter coffee, 250ml, 1-2 hours after breakfast. I have this gap to not have my coffee interfere with absorption of certain nutrients (iron, calcium, etc.). I have never tested my levels with or without this gap and am not even sure whether 1-2 hours is enough for gastric emptying of my breakfast/nutrient absorption, so this is not in any way a scientifically validated approach.

I usually have a decaf coffee later in the day, since decaf seems to confer most of the health benefits (esp. cardiovascular health, polyphenol content, fibre) of regular coffee.

I rarely drink espresso due to kahweol and cafestol and their negative impact on LDL-C absorption.
