While there are a few types of food that can help you work toward your daily zinc goals (we’re looking at you, oysters), if you aren’t being intentional, it can sometimes be difficult to adequately nourish your body and reach your zinc needs. And if you’re trying to leverage more concentrated doses for immune-centric goals or otherwise, your approach may need to change.*
Zinc sulfate is perhaps one of the most common; however, this form may lead to an upset stomach when taken without food, so keep this in mind when choosing the less expensive option. There’s also the issue of absorption, to get the most out of your zinc intake. In supplement form, zinc bisglycinate offers the most benefit, as clinical research has demonstrated its ability to be significantly more bioavailable (and gentle) than its counterparts.* As for food, zinc is often found in meat and other animal products, but that doesn’t mean plant-based eaters are left out. “There are a lot of sources of zinc in plant-based diets,” says Seattle-based registered dietitian nutritionist, Ginger Hultin, M.S., RDN, owner of ChampagneNutrition and author of Anti-Inflammatory Diet Meal Prep and How To Eat To Beat Disease Cookbook, including “soy foods, beans, whole grains, nuts, seeds, and dairy products (if they’re included).” Here, a few go-to sources to consider (for more detail, check out our roundup of zinc-rich foods): However, your body could benefit from even more zinc than just the baseline recommendation. “That’s a minimum requirement. For optimal health and targeted support (think immunity), zinc needs are thought to be even higher2 (15 to 30 milligrams),”* notes mbg’s vice president of scientific affairs Ashley Jordan Ferira, Ph.D., RDN. Another compelling reason to consider zinc inputs in your nutrition ritual with some intention is the significant number of people with a zinc gap. “Considering food sources alone, 15% of U.S. adults are not getting enough zinc2,” warns Ferira, making supplementation a potential asset to any diet. That’s over 30 million Americans, to put things in perspective. Zinc is especially important during the growth and development phase of life, but there are other people who may have a higher risk of lacking zinc in their diet or whose bodies are utilizing the mineral more rapidly and thus have increased needs. Consult with your doctor to see if you might fall into these categories. For the most part, your daily zinc consumption shouldn’t regularly exceed 40 milligrams. If you take more than this over time, you may experience mild gastrointestinal upset, and it may interfere with your body’s absorption of other important minerals (such as magnesium, iron, and copper). As with most updates to your supplement regimen, it’s always helpful to check with a nutrition-minded health care practitioner when considering a zinc supplement, particularly if you have key health considerations or concerns.
