Ask HN: Does coffee affect vitamin absorption?

1 pointsby stevofolifeover 2 years ago

I’m wondering if drinking coffee while taking vitamins will affect the efficiency and efficacy of how the vitamins are absorbed. Is it better to eat vitamins first, wait a little, then drink coffee? If so, how long should one wait?

Coffee reduces absorption of B vitamins and may affect vitamin-D receptors. There are many studies on this on nih.gov you may find useful.
