If you've ever wondered what it actually takes to slow down aging - not just on the surface, but at the cellular level - this episode is for you. Kylie sits down with Dr. Jeff Gross, a neurosurgeon turned regenerative medicine pioneer and founder of ReCELLebrate, to talk about everything from the foundational habits that protect your cells, to the cutting-edge world of stem cells, exosomes, and peptides.

What we loved most about this conversation is that Dr. Gross doesn't just geek out on the advanced stuff - he keeps bringing it back to what your grandmother already knew. Sleep. Move your body. Eat your vegetables. And yes, eat your pomegranates.

We also got into something I haven't talked about on the podcast before: mitochondrial health and why it might be the missing piece when it comes to your energy, your hormones, and even your brain. If you're in your 30s or 40s and feeling like something is just off, this episode might give you some answers.

About Dr. Jeff Gross

Dr. Jeff Gross graduated from UC Berkeley with a degree in biochemistry and molecular cell biology and earned his MD from George Washington University School of Medicine in 1992. He completed his neurosurgical residency at UC Irvine and a Fellowship in Spinal Biomechanics at the University of New Mexico. Board-certified by the American Board of Neurological Surgery, Dr. Gross has been recognized by Top Doctor as a leading neurological surgeon since 2020 and received HealthTap's 2022 Top Doctor Award.

He is the founder of ReCELLebrate, a regenerative medicine practice built on the philosophy that surgery should be a last resort - and that modern biochemistry offers powerful tools to help the body heal and age well.
