Mikkipedia is an exploration in all things health, well being, fitness, food and nutrition. I sit down with scientists, doctors, professors, practitioners and people who have a wealth of experience and have a conversation that takes a deep dive into their area of expertise. I love translating science into a language that people understand, so while some of the conversations will be pretty in-depth, you will come away with some practical tips that can be instigated into your everyday life. I hope you enjoy the show!

Mini Mikkipedia - Is Low Stomach Acid Wrecking Your Digestion?
#359
Last Sunday at 7:00 PM

In this Mini Mikkipedia episode, Mikki dives deep into a surprisingly common but often misunderstood issue: low stomach acid (hypochlorhydria).

Mikki explains how stomach acid is foundational not just for breaking down food, but also for absorbing nutrients, protecting against pathogens, and even supporting mental clarity. She unpacks the causes of low acid, key symptoms to watch for, and evidence-based ways to naturally support healthy stomach acid levels. This is a must...
