When you’re working long hours on-site, your body takes a beating—and keeping it healthy requires addressing common nutrient deficiencies. While zinc might not always get the spotlight, it plays a big role in maintaining overall health. From supporting your immune system to helping your skin heal, this mineral is involved in countless processes your body relies on every day. The problem? Most people don’t get enough of it. Sources like oysters, red meat, and beans are a great way to bulk up your zinc intake.

Quick look

• 15% of adults are zinc deficient, leading to slower recovery, lower energy, and weaker immune systems.
• Zinc is critical for immune support, wound healing, and reducing inflammation, making it a must-have nutrient for anyone with an active lifestyle.
• Oysters, red meat, poultry, beans, and dairy are top food sources of zinc, while supplements like zinc picolinate and citrate are great for filling in gaps.
• To supplement effectively, choose third-party-tested supplements free from unnecessary additives and provide the recommended daily allowance (11 mg for men, 8 mg for women).

What is zinc and why is it important?

Zinc is a trace mineral that is only required in small amounts for optimal function—but that small amount goes a long way. It’s involved in over 300 enzymatic reactions, helping with everything from immune function and wound healing to DNA synthesis and cell division. Despite its importance, zinc deficiency is surprisingly common. Studies show that roughly 15% of adults in the U.S. don’t get enough zinc through their diet. This number could be even higher globally, especially in regions with limited access to zinc-rich foods. One reason for this widespread gap is that our bodies can’t store zinc, so we must consume it regularly through food or supplements. 

Why we need zinc

For trade workers in physically demanding jobs, zinc becomes even more critical. It helps you recover faster, fight off illnesses, and keep your energy levels in check. Here is a breakdown of the many ways this mineral works to keep you at your best.

Immune support

Zinc plays a major role in keeping your immune system in top shape. While it serves many functions, the main one includes keeping the thymus and bone marrow functioning normally, which are responsible for generating immune cells. By keeping these healthy, the body can create and activate immune cells that fight off infections and illnesses. Studies show that zinc can shorten the duration of colds by up to 33% and may reduce the severity of respiratory infections. For construction workers exposed to dust, weather changes, and long hours, a strong immune system can be a game changer in getting back to work.

Men’s health

Zinc is especially important for men’s health. It supports testosterone production, which affects everything from muscle growth to energy levels. It also plays a role in fertility by improving sperm quality and motility. Maintaining healthy zinc levels can also help with prostate health, making it a must-have nutrient for men of all ages.

Wound healing

Cuts, scrapes, and bruises are part of the job, but zinc can help you bounce back faster. This mineral is crucial for tissue repair and helps speed the healing process by supporting collagen production and reducing inflammation. If you’re constantly dealing with minor injuries, zinc can give your body the boost it needs to recover quickly.

Skin health

Zinc is often called the “skin mineral” for a reason. It regulates oil production and helps prevent inflammation, making it effective for conditions like acne and eczema. For construction workers exposed to harsh weather and environmental irritants, zinc helps keep your skin healthy and resilient.

Regulates inflammation

Zinc is key in regulating inflammation and reducing your risk of chronic conditions like arthritis and heart disease. Its anti-inflammatory and antioxidant properties protect your body from long-term damage, which is especially important for those with physically demanding jobs.

Energy production

Feeling drained by midday? Zinc plays a role in energy metabolism, helping your body break down nutrients like carbs, fats, and proteins into usable fuel. It also helps to keep your enzymes and mitochondria functioning properly, which are directly involved with energy production. Healthy zinc levels will keep you going strong even on your busiest days.

Muscle repair and growth

Your muscles take a hit daily on the job, and zinc helps repair and rebuild them. It supports protein synthesis, which is essential for muscle recovery and growth. For anyone lifting heavy loads—on or off the clock—zinc can help your body handle the strain.

Bone health

Construction workers need to maintain strong bones, and zinc helps with that, too. It works alongside calcium and vitamin D to build and maintain bone density, reducing the risk of fractures and long-term joint problems. Because bone density tends to decrease with age, ensuring optimal zinc levels helps to protect against long-term health complications.

Where to find zinc

Knowing where to get zinc is the first step to making it a regular part of your routine. Whether you prefer to get your nutrients through food or need the extra support of a supplement, there are plenty of options to help you meet your needs. Here are some of the best sources of zinc and how to choose the right supplement if you’re falling short.

Food sources

Incorporating zinc-rich foods into your diet is a natural way to meet your daily requirements. Here are some of the best natural sources:

• Oysters: They are among the richest sources of zinc, with a 3-ounce serving providing 32 mg. This exceeds the total recommended intake of 11 mg for men and 8 mg for women, so oysters should be consumed in moderation.
• Red meat and poultry: Beef, lamb, and chicken are excellent sources of zinc. For example, three ounces of cooked lean ground beef offers about 5.4 mg of zinc.
• Shellfish: Crab and lobster are good options; a 3-ounce serving of cooked crab contains approximately 6.5 mg of zinc.
• Legumes: Chickpeas, lentils, and beans provide zinc, although in less bioavailable forms due to phytates that can inhibit absorption. For instance, a cup of cooked lentils has about 2.5 mg of zinc.
• Nuts and seeds: Pumpkin seeds and cashews are notable sources; one ounce of pumpkin seeds contains around 2.2 mg of zinc.
• Dairy products: Milk and cheese contribute to zinc intake; an ounce of cheddar cheese offers about 0.9 mg.
• Whole grains: Foods like quinoa, oats, and whole wheat bread contain zinc, but like legumes, phytates can reduce absorption.

Quality supplements

Supplements can be a practical solution if you cannot meet your zinc needs through diet alone. Here are some commonly available forms:

1. Zinc gluconate: One of the most common over-the-counter forms, often used in cold remedies like lozenges.
2. Zinc citrate: This form is well-absorbed and has a more appealing taste, making it a good option for supplementation.
3. Zinc picolinate: Some studies suggest this form may be better absorbed than others, potentially making it more effective for increasing zinc levels.
4. Zinc acetate: Often used to reduce the duration of the common cold.

When choosing a zinc supplement, ensuring you’re getting a product that’s effective, safe, and worth your investment is important. Not all supplements are created equal, and picking the right one makes a big difference in how your body absorbs and uses the mineral. Factors like bioavailability, dosage, and quality impact how well the supplement works for you. To help you navigate your options, here’s what to look for when selecting a zinc supplement:

• Bioavailability: Choose forms your body can easily absorb, such as zinc picolinate or citrate. These forms are more effective at raising zinc levels than others.
• Dosage: To avoid side effects, follow the recommended dietary allowance (RDA). Adult men should aim for 11 mg daily, while adult women need 8 mg.
• Quality assurance: Look for supplements that have been third-party tested for purity and potency. This ensures the product contains what it claims and is free of contaminants.
• Additives: Avoid supplements with unnecessary fillers, artificial colors, or preservatives. A cleaner product is always better for your health.

Tips for supplementing with zinc

Adding a zinc supplement to your routine can boost your health, but it’s essential to do it right. Here are some practical tips to help you get the most out of your zinc supplementation:

1. Take with food

Taking zinc on an empty stomach can sometimes cause nausea. To avoid this, it is best to take your zinc supplement with a meal or snack. This not only reduces the chance of stomach upset but also enhances absorption.

2. Timing with other nutrients

Zinc can interfere with the absorption of certain minerals, particularly iron and copper. To minimize this interaction:

• Separate intake: If you’re taking iron or copper supplements, consider taking them at a different time of day than your zinc supplement. This spacing helps ensure that all minerals are adequately absorbed.
• Balanced diet: Consuming a well-rounded diet that includes a variety of nutrients can help maintain proper mineral balance and reduce the risk of deficiencies.

3. Avoid excessive doses

While zinc is essential, more isn’t always better. High doses of zinc can lead to adverse effects, including nausea, headaches, and interference with absorbing other vital minerals. Stick to the recommended dietary allowances unless advised otherwise by a healthcare professional.

4. Consult a healthcare provider

Before starting any new supplement regimen, it’s wise to consult with a healthcare provider. Getting tested to see whether or not you are low on zinc is the first step to knowing whether or not you should be taking it. Healthcare providers will give you personalized advice based on your health status and nutritional needs, ensuring appropriate zinc supplementation.

Bottom line

Zinc is a powerhouse mineral that supports your immune system, skin health, and energy levels—all while helping your body recover and perform at its best. Whether you’re getting it from food or supplements, making zinc a regular part of your routine is an easy step toward better health. Remember to choose quality sources, time it right with other nutrients, and always follow recommended guidelines to avoid overdoing it.
