Key Takeaways
Zinc is a mineral that plays an important role in your body’s immune function by supporting immune cell health, development, and signaling.
You can find zinc in many food-based sources, and you can also turn to supplementation to make sure you’re getting the recommended daily amount.
Incorporating zinc into your daily routine is straightforward: focus on zinc-rich foods and, when needed, use targeted supplementation to fill nutritional gaps.
Zinc is an essential trace mineral, which is a mineral that your body only needs in small (trace) amounts, but which is still essential for normal growth, development, and overall health.
While your body may need zinc only in small amounts, it cannot produce or store it on its own,2 meaning it needs to be consumed and replenished regularly through either diet or supplementation.
Zinc plays a large role in helping support the body’s overall health, especially when it comes to the immune system. Research has shown that adequate zinc levels support normal immune function, skin health, and the body’s natural recovery processes.3 For this reason, zinc is often included in immune-support supplements. Some studies suggest zinc supports immune system function during times when the body needs additional nutritional support.
It’s crucial for the development and function of immune cells.4 Adequate zinc levels are critical for the activation and survival of key immune cells and immune responses, as well as the regulation of immune responses. Meanwhile, low zinc levels can disrupt the signaling pathways that guide how immune cells function.5
It supports the integrity of physical, protective barriers that contribute to your immune system.6 These barriers, such as your skin and the lining of your respiratory tract, are part of the body’s natural protective mechanisms that support overall immune health.7,8
It has antioxidant properties.9 This means zinc may help protect your cells from damage caused by unstable molecules called free radicals; in other words, it helps your body defend itself against cellular wear and tear caused by oxidative stress.
Research shows that zinc:
Luckily, zinc is found in many foods, so it’s definitely possible to meet daily needs through a balanced diet. Good dietary sources of zinc include meat, shellfish, legumes, seeds, nuts, dairy, and whole grains.
Examples of animal-based zinc sources include:
Plant-based sources include:
Those who might not get enough zinc through their diet—such as vegetarians or older adults—zinc supplementation can step in to help support immune health. Common forms include zinc gluconate, zinc picolinate, and zinc citrate. .Zinc citrate is a gentle, absorbable version of zinc that’s easy for the body to use. A daily scoop of AG1 includes 20 mg, or 182%DV, of zinc citrate.
Because the body doesn’t produce zinc, it’s important to maintain a consistent dietary intake. Normal daily activity can deplete your zinc2 (and other vitamin stores as well). Plus, stress and periods of intense physical activity11 can reduce the body’s zinc supply (while utilizing stores of other nutrients and minerals as well).
Establishing a routine that includes regular zinc intake supports long-term immune health naturally and sustainably.
In conclusion, zinc is a foundational nutrient that supports immune cell function and signaling, strengthens protective barriers, aids in DNA synthesis and cell division, and more. This makes it an essential component of the body’s defense system and total well-being. Drinking ensures you’re receiving a daily, necessary amount of zinc—and more.
Alongside the many other vitamins and minerals that support overall health and immunity, the addition of zinc in AG1’s formula makes it a uniquely comprehensive approach to supporting immune function.
