Coffee Overload: 700ml Too Much?

by Mads

Is 700 ml of coffee too much?

If you are a coffee lover, the idea of drinking 700 ml of coffee may seem like heaven. However, it turns out that anything above 400-500 mg of caffeine can lead to various side effects, such as increased heart rate, anxiety, jitters, and insomnia.

According to the Dietary Guidelines for Americans, moderate caffeine consumption ranges between 200 and 300 mg per day, which is equivalent to about one to three cups of coffee. Going over this amount may lead to health issues. But is 700 ml too much for a one-time daily dose?

Well, it depends on the individual’s sensitivity to caffeine, tolerance level, and overall health condition. For some people, 700 ml (about three cups of coffee) could be just fine, while for others, it might be an excessive amount that can cause unwanted effects.

It’s worth noting that the way you consume coffee can also impact the caffeine intake. For instance, a shot of espresso contains less caffeine than a regular brewed coffee cup. But, if you drink a large latte with three espresso shots per day, you might exceed the recommended daily caffeine limit.

Besides, the type of coffee bean, roast, and preparation method can also affect the caffeine content. For example, dark-roasted beans contain less caffeine than lighter roasts, and a French press tends to extract more caffeine than a drip coffee machine.

How to determine your optimal daily caffeine intake?

If you are not sure about your caffeine tolerance level, here are some tips to help you figure it out:

– Start by tracking your caffeine intake for a week and see how your body reacts to it. Note down the amount of caffeine in every drink you have, the time of day you consumed it, and any symptoms you experienced afterward.
– Keep in mind your age, weight, and overall health condition, as these factors can influence your caffeine metabolism.
– Gradually increase your caffeine intake by adding small amounts to your daily routine and see how your body responds.
– Talk to your doctor or nutritionist, especially if you have a medical condition or are taking medication that might interact with caffeine.

The best time to drink coffee

Apart from the amount and type of coffee, the timing of your coffee consumption can also affect your health and productivity. Here are some pointers on when to drink coffee to get the most benefit:

– Avoid drinking coffee right after waking up, as during this time, your cortisol levels are naturally high. Consuming caffeine at this point may lead to reduced cortisol production and disrupt your natural circadian rhythm.
– The optimal time for coffee intake is about 30 minutes to an hour after waking up when your cortisol levels start to decline. This timeframe ensures that caffeine doesn’t interfere with your cortisol production and enhances alertness and productivity.
– Avoid drinking coffee in the late afternoon or evening, as caffeine has a half-life of about 5-6 hours. Thus, drinking coffee too close to bedtime may lead to insomnia or restless sleep.

Coffee alternatives

If you’re looking for coffee alternatives that can still provide you with an energy boost and taste delicious, here are some options:

– Matcha tea: This Japanese green tea packs caffeine and healthy antioxidants that can boost focus and metabolism. Plus, matcha’s natural sweetness and earthy taste make it a great coffee substitute.
– Yerba Mate: This South American tea is known for its energizing and soothing effects. Yerba Mate contains natural caffeine and various vitamins that can enhance physical and mental performance.
– Chai tea: This Indian tea blend contains spices like cinnamon, ginger, and cardamom that can awaken your senses and offer a warm, comforting taste. Chai tea has less caffeine than coffee but enough to provide a gentle kickstart to your day.


In conclusion, 700 ml of coffee could be too much for some individuals, but not necessarily for others. The amount of coffee that you can consume without experiencing any side effects depends on your tolerance level, caffeine sensitivity, and overall health condition. To avoid any adverse effects, it’s best to keep your caffeine intake within the recommended daily limit and pay attention to the timing and preparation of your coffee. Don’t forget that there are also tasty coffee alternatives that can offer you the same energy boost without the jitters or crashes.
