Health Reference LibraryWhen is the best time to take zinc, and should you take it with food?
This entry is part of the Nutri Tailor Health Reference Library — cited research on supplements, nutrients and adjacent areas of health.
Summary
With the evening meal. Zinc on an empty stomach makes a large minority of people feel sick, and food removes that at the cost of a little absorption that does not matter at 8 to 15 mg a day. The evening also keeps zinc away from a morning iron dose and away from coffee. Choose a meal with meat, fish, eggs or dairy rather than a bowl of bran or beans, whose phytates bind it, and keep it two hours from high dose iron or calcium supplements. Cold lozenges are the exception: they work by bathing the throat and are taken through the day.
Effective dose
Daily at maintenance doses. Anything above 25 mg a day should be a defined course of weeks with copper alongside, not a standing habit.
Timing
With a meal, and the evening meal is the natural slot. Zinc on an empty stomach causes nausea in a large minority of people, and food removes that at the cost of a little absorption, which does not matter at 8 to 15 mg a day. The evening keeps zinc away from a morning iron dose and away from coffee. For a cold, lozenges are the exception: they work by bathing the throat, so they are taken through the day at the first sign of symptoms.
Interactions
Yes, with food, but not with the foods that bind it hardest: a large bowl of bran or beans lowers absorption through phytates, so a meal with meat, fish, eggs or dairy is the better companion. Keep zinc two hours away from iron and calcium supplements if you take those at high doses.
Practical framework
From the Nutri Tailor range: [zinc picolinate capsules](/products/zinc), 8 mg; [Super Zinc liquid](/products/super-zinc), 8 mg per ten drops, all made in the UK. This is a summary of published research, not personal health advice. Talk to your GP or a registered nutritional therapist before changing what you take, especially if you are pregnant, have a diagnosed condition or are under ongoing care.
Common misconceptions
That the hour matters more than the habit: for zinc the daily total and the weeks of use decide the result. That an empty stomach is always better: for zinc the answer is above, and comfort keeps people taking it.
