How Much Coffee Is Too Much? Melanin & Morning Risks

If your day starts with a cup of coffee—like millions of people—you might want to rethink that habit. According to UK dietitian Amanda Ursula, that early cup could be doing more harm than good, affecting both your energy and focus throughout the day.

The key number: limit yourself to no more than three cups of coffee per day, and avoid having more than 70 grams (roughly 3 small cups) before noon to prevent skin dullness from melanin buildup.

Why Morning Coffee Can Backfire

Drinking coffee with breakfast may seem like a productivity boost, but it often has the opposite effect. Ursula explains that caffeine on an empty stomach increases your heart rate and causes stomach contractions. Meanwhile, the sugars you eat at breakfast are quickly absorbed, leading to a blood sugar crash. This leaves you feeling irritable, distracted, and ravenous—not the ideal state for starting your day.

The Best Time for Coffee: Midday Benefits

Lunchtime is actually the sweet spot for coffee, according to Ursula. A small cup with a lean protein-based meal—like fish or eggs—can sharpen your focus and fight the post-lunch slump. Eggs, in particular, are linked to improved memory. But skip heavy carbs like pasta or fried pancakes at lunch; they can slow brain function and drag down your concentration.

How Much Coffee Is Safe—And When

Russian nutritionist Margarita Koroleva advises keeping your daily coffee intake under three cups and limiting consumption before noon to 70 grams or roughly three small servings. Why? Too much coffee leads to melanin accumulation in the body, which can leave your skin looking dull and lifeless. Timing matters: spread out your coffee intake and avoid overdoing it in the morning hours.

Frequently Asked Questions

Is it bad to drink coffee first thing in the morning?

Russian nutritionist Margarita Koroleva recommends no more than three cups of coffee per day to avoid negative effects like melanin buildup and skin dullness.

Lunchtime is ideal. A small coffee with a light, protein-rich meal like fish or eggs can improve alertness and memory without the downsides of morning caffeine on an empty stomach.
