Ask HN: Does coffee affect vitamin absorption?

1 points by stevofolife 3y ago ↗ HN

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?

ResearchGate is your friend.

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.

Makes me wonder why so much 'energy drinks' contain B-vitamins? As prophylactic compensation measure?

That would make sense. Depletion of B12 would be bad especially for people that sit a lot such as gamers increasing their risk of blood clots in the legs.
