Welcome To Bio Aligned Wellness

Bio Aligned Wellness is a functional nutrition practice grounded in science, compassion, and personalized healing. Founded by a PhD-trained functional dietitian, we specialize in uncovering the root causes of chronic digestive and hormonal imbalances—starting in the gut.

Our clinical approach integrates functional testing like the GI-MAP, DUTCH hormone testing, and food sensitivity and allergy panels to uncover hidden contributors to symptoms like bloating, irregular cycles, fatigue, and inflammation. From there, we design targeted, evidence-based protocols that combine nutrition, lifestyle, and therapeutic supplements to restore alignment between your biology and your wellbeing.

Whether you’re navigating IBS, SIBO, hormone imbalances, or unexplained fatigue, Bio Aligned Wellness helps you reconnect with your gut and your health—so you can heal from the inside out.

About Dr. Mariela Fierro

I became passionate about gut health after spending decades battling digestive issues myself. Constant bloating, discomfort, and pain after nearly every meal were a daily reality—one I knew far too well. Despite trying countless conventional treatments and being repeatedly prescribed antacids, nothing truly helped. At my lowest point, I turned to my husband and said, “I hate eating.”
It wasn’t a lifestyle choice—it was a fight for comfort and peace in my own body. Even the healthiest meals left me in pain.

I’ll never forget the moment a patient said those exact same words to me during a consultation—through tears “I hate eating.”

Her words hit me like a wave. I knew exactly how she felt, because I had lived it too.

That moment changed everything. It reminded me why I dug deeper into the root causes of gut dysfunction and committed myself to functional nutrition. I discovered what conventional approaches often overlook: the gut requires a precise balance of nutrients and beneficial bacteria in order to heal. Without it, imbalances like dysbiosis can wreak havoc on the entire body.

Once dysbiosis was corrected, her symptoms disappeared. The bloating, the pain, the discomfort… gone. Her transformation was profound. She couldn’t believe that after so many years of suffering, relief had finally come.
