Dr. MaryBeth Ayer

Dr. MaryBeth Ayer's Journey

Her health journey began in the wake of overwhelming stress that brought her life to a sudden and devastating halt. At just 23 years old, she was nearly immobilized overnight—everyday tasks became unmanageable. She battled relentless fatigue, constant nausea, intense muscle and joint pain, severe gut dysfunction, anxiety, depression, brain fog, and unexpected weight gain of nearly 60 pounds.

Faced with little clarity and no lasting solutions, she became her own doctor—relentlessly researching, experimenting, and healing. That turning point ignited a passion that transformed her life. Today, she uses that hard-earned knowledge and experience to help others reclaim their vitality and thrive in their own journey toward optimal health and well-being.

She deeply sympathizes with the health challenges of others and is able to assist others to overcome their health issues by getting to the root causes.

“Dr.MaryBeth gave me my life back. After a long period of stress I found myself debilitated with exhaustion and nausea. It felt like I had been hit with a ton of bricks and I was unable to function. Because of her help, I am aware of my body and see a complete difference when I follow what she has said. If it wasn’t for her, I would still be in bed everyday unable to function. I have my life back!”
