Can These Mushrooms Heal Your Gut, Stop Alzheimer’s, & Fight Cancer? | Dr. Catalina
Your neurons can become younger.
Your gut can reshape itself in five days.
Your immune system can learn to fight cancer.
This isn't theory. It's mycology.
And it's about to change how you think about what your body can do.
This week on Live Well Be Well, I sit down with Dr. Catalina Fernández de Ana Portela, a pioneering mycologist and oncologist who’s spent 26 years unlocking the therapeutic power of mushrooms. From Lion’s Mane and Reishi to Cordyceps, she’s led clinical trials across cancer, autism, neurodegenerative disease, and fertility, quietly reshaping how we think about prevention, healing, and the intelligence of nature.
In this episode, we explore:
The real science behind Lion's Mane: neuroplasticity, contains GABA, and why your neurons can actually become younger
Why Lion's Mane may support brain health, gut health, autism, Alzheimer's, multiple sclerosis, and Parkinson's treatment
How Reishi could help reduce stress and anxiety, and modulate neurotransmitters like GABA
The real science behind putting mushrooms in your coffee (yes, it's more than a trend!)
What Cordyceps does for energy, fertility, and performance, and how mushrooms support both male and female reproductive health
Breakthrough research on mushrooms in integrative oncology, including their effects on the gut microbiome and immune system
The gut-brain axis: how mushrooms can reshape your microbiome in 5 days and support conditions from autism to cancer
The supplement quality crisis: why only 25% of products contain what they claim and how to find trustworthy brands
Whether you're curious about adding Lion's Mane to your morning coffee, wondering if Reishi could actually help your anxiety, or want to understand how mushrooms are being used alongside chemotherapy in clinical trials, this conversation will change how you think about what's possible. The question isn't whether mushrooms work. The science is undeniable. Now it's about finding the right approach for you.
Love,
Sarah Ann 💛
