Why Zinc Supplements Make You Nauseous | Stephen Kavanagh

Why do zinc supplements make some people nauseous or upset their stomach?

In this episode of the Brain Fitness Podcast, I sit down with Stephen Kavanagh to discuss synthetic vs. food-based zinc, OysterMax®, digestion, and brain health.

Stephen Kavanagh is a marine biologist and the Founder & CEO of Marine Health Foods Ltd. in County Wicklow, Ireland. With more than 30 years of experience in marine science, he graduated from the School of Ocean Sciences at the University of Wales, Bangor. His work has focused on the health benefits of marine nutrition, particularly through the company's flagship product, OysterMax®, a nutrient-dense oyster extract that supports overall wellness, including sexual health, energy, hormonal balance, and skin health.

In this conversation, Stephen explains why oysters are among nature's most nutrient-dense foods, naturally providing zinc, copper, selenium, and vitamin B12—nutrients that support normal cognitive function, nervous system health, and protection against oxidative stress.

We also explore why not all zinc supplements are created equal, the potential advantages of food-based minerals, and why Stephen's advice is simple: "Think before you zinc."
