Depends

A simple, USP Verified zinc tablet, best used with care

A Walmart listing shows 4.8 out of 5 from 317 ratings for a 100-count Nature Made Zinc 30 mg bottle, and the listing and a grocery page both carry a USP Verified claim. Research is less exciting: a Cochrane review found zinc gave little to no benefit in cold prevention, though it may shorten a cold. At 30 mg, the dose is well above the 8 to 11 mg adults typically need per day, so it makes sense mainly if a doctor or pharmacist suggests it.

Skip it if you…

  • already take a multivitamin or other products with zinc and want to avoid doubling up
  • expect it to prevent colds
  • are pregnant, on medication or managing a health condition, unless a doctor agrees

Nature Made Zinc 30 mg is a tablet taken once a day. A Kroger listing says it is gluten free and vegan with no added color, artificial flavors or preservatives, and that the directions are one tablet daily with water and a meal. Each tablet is listed at 273% of the Daily Value.

What buyers like

A high retailer rating.Walmart shows 4.8 out of 5 from 317 ratings. The page had no written review text, so we can only report the score.
USP Verified.Kroger says USP has tested and verified the ingredients, potency and manufacturing process. Walmart carries the same claim, though an asterisk there was not explained.
Simple and no extras.No added color, artificial flavors or preservatives, per the listing.

What to keep in mind

Little benefit for cold prevention.The Merck Manual, summarizing a Cochrane review of 34 trials, says zinc provides little to no benefit in cold prevention, though it may shorten an ongoing cold.
The dose is well above daily needs.The same source gives an adult recommended intake of about 8 to 11 mg per day. A 30 mg tablet is much more, so count zinc from a multivitamin and other products too.
High zinc can cause problems.The Merck Manual notes toxicity can occur at high doses and that zinc can displace other necessary metals. Zinc lozenges commonly cause nausea and taste changes.
Limited review text.We could not read many written buyer reviews, so we do not know what people say about long-term use or stomach upset.

How it holds up over time

We found no long-term owner accounts. Because the daily dose is high, the sensible way to use it is for a defined reason, ideally with advice from a doctor or pharmacist, and with your total zinc intake in mind.

Tips

  • Take it with a meal, as the directions say.
  • Add up zinc from all your supplements.
  • Do not use it as a cold shield. Evidence for prevention is weak.
