Does caffeine have an effect on nutrients absorbed by the body?
Yes, caffeine promotes the excretion of calcium which is released in excrements and inhibits the calcium absorbed in the small intestine. It also limits Vitamin D, magnesium, zinc, copper, and iron absorption which decreases overall health. Caffeine also increases urination. In moderation, 2-4 8 oz cups of coffee per day, caffeine is not too influential, but too much could affect overall health.
