Zinc might be one of the most underrated supplements on the shelf—but according to experts, taking it consistently can have noticeable effects on your energy, immunity, sleep, and overall recovery.
Zinc is an essential trace mineral involved in more than 300 enzymatic reactions in the body. Because we don’t store large amounts of it, daily intake—through food or supplements—is crucial. When levels are low, symptoms like fatigue, frequent colds, slow wound healing, and poor sleep can start to creep in.

More Energy and Better Recovery
Dr. Stephen Cabral explains in a video that zinc is “one of the most powerful anabolic minerals in the entire world,” meaning it plays a key role in building and repairing tissue. When taken regularly, zinc helps the body repair muscle tissue after workouts, which can translate to less soreness, faster recovery, and improved physical performance over time.
This muscle-repair benefit can also support better daily energy. When your body isn’t constantly playing catch-up from inflammation or poor recovery, you’re more likely to feel steady, sustained energy rather than crashes throughout the day.
A Stronger Immune System
Zinc is perhaps best known for its immune-boosting properties. It supports the development and function of immune cells and helps regulate inflammation. Studies have shown that adequate zinc levels may reduce the duration and severity of common colds and infections.
Dr. Cabral notes that zinc “will help to boost the immune system,” making it especially valuable during times of stress, heavy training, travel, or seasonal illness when your defenses may be compromised.
Deeper, More Restorative Sleep
One lesser-known benefit of zinc is its impact on sleep quality. According to Dr. Cabral, zinc “does its best work at night,” which is why he recommends taking it at dinnertime. Zinc supports hormone production and nervous system regulation, both of which are essential for falling asleep and staying asleep.
For people who struggle with light, restless sleep—or who wake up feeling unrefreshed—consistent zinc supplementation may contribute to deeper, more restorative rest over time.
The Bottom Line
Dr. Cabral advises taking zinc with food, ideally at dinner, because it can cause nausea if taken on an empty stomach. Pairing it with a meal not only improves tolerance but also enhances absorption.
It’s also important not to overdo it. Excessive zinc intake over long periods can interfere with copper absorption and lead to imbalances. Most experts recommend staying within safe daily limits unless otherwise directed by a healthcare provider.
When taken daily and in appropriate doses, zinc supplements can support more energy, faster muscle recovery, a stronger immune system, and better sleep. Timing matters—taking zinc with food in the evening allows it to work in sync with your body’s natural repair processes. As with any supplement, balance is key, but for many people, zinc can be a simple addition with wide-reaching benefits.
