What deficiencies does coffee cause?
Caffeine has a mild diuretic effect, which leads to an increase in urination. As a result, water-soluble vitamins, such as B-vitamins and vitamin C can be depleted due to fluid loss. Research also demonstrated that the higher the level of caffeine, the more it interfered with vitamin D absorption. Coffee may lower the absorption of both vitamin D and calcium: Research suggests that higher caffeine intake is associated with lower levels of vitamin D.However, excessive coffee consumption may lead to low levels of certain nutrients, like iron and calcium, especially in people with poor dietary intake and those with preexisting health conditions.It should be safe for you to drink coffee if you have a liver condition.
