Coffee consumption: can caffeine make my body lose vitamins and minerals?
4 doctors weighed in across 2 answers
Yes, slightly: Good question. I found evidence that people lose about 5 mg of calcium when they have a cup of coffee-but that is a tiny amount. Caffeine may interfere with vit. D metabolism & reduce absorption of iron, zinc, magnesium & other minerals & increase excretion of b6 & other b vits but it's hard to find solid research on this. However, most sources of caffeine have beneficial antioxidants.See comment:.

Probably not: Most such claims are internet exaggerations of real scientific work. Caffine is the most popular and probably the most studied of all drugs, and serious adverse effects in real life have resisted demonstration. There are "pop" claims about caffeine interfering with absorption of iron and vitamin d; if there were any real effect on real human beings, it would be obvious by now.
