What Are Zinc Caps?

Research shows that zinc deficiency is widespread, especially in the elderly. Supplementing with zinc is an effective way to support aging immune systems. Since absorption can sometimes be problematic, we’ve developed a low-cost formulation that combines the highly bioavailable OptiZinc® with zinc citrate to provide a potent 50 milligram dose of zinc in each capsule.

OptiZinc® contains one of the most absorbable forms of zinc, zinc methionate, which is prized for its superior bioavailability.

Zinc Caps Benefits

  • Provides immune system support
  • Supports cardiovascular & neurological health
  • Helps maintain vision

Beyond Immune Health Support

Zinc is well known for its immune health benefits, but it goes beyond that. For instance, zinc is an essential component of superoxide dismutase, one of your body’s most powerful natural antioxidants. It also supports cardiovascular and neurological health, and helps maintain vision in the elderly.

Why Should I Supplement with Zinc Caps?

We all know that zinc plays a crucial role in our health and wellness. It's great for supporting our cardiovascular and neurological health, but it's mostly known for promoting immune system health.

You may not be aware that zinc can be hard for your body to absorb. To help, our experts packed a potent 50 milligram dose in each capsule of our Zinc Caps.  But what really sets Zinc Caps apart is that it provides optimum absorption into your body by combining a highly bioavailable form of zinc and zinc citrate. Preclinical studies indicate these ingredients circulate in your body longer, so you're absorbing more and getting the maximum benefits.
