What if PCOS, thyroid dysfunction, chronic inflammation, fertility concerns, and post-viral illness aren’t completely separate health problems, but connected chapters of a much bigger story? In this episode of Modern Thyroid and Wellness, McCall McPherson sits down with Nicole Peterson Doran, co-founder of PUR-FORM and host of The Healthspan Collective podcast. Nicole shares her personal journey from being diagnosed with PCOS at just 16 and later hypothyroidism to discovering functional and integrative medicine, preparing for pregnancy, navigating long COVID and mast cell activation syndrome, and ultimately helping build businesses focused on personalized health optimization and regenerative medicine. Together, McCall and Nicole explore why there is no one-size-fits-all approach to healing, how foundational habits and personalized care can work together, and how emerging tools such as GLP-1 medications, peptides, EBO2, and regenerative therapies are becoming part of a broader conversation around complex health challenges. 🔑 Key Topics Covered Nicole’s PCOS diagnosis at age 16Developing hypothyroidism after her PCOS diagnosisWeight gain, inflammation, fatigue, brain fog, and hormonal symptomsWhy birth control and metformin did not address everything she was experiencingHow functional and integrative medicine changed her health journeyMoving beyond calorie counting toward whole-food nutritionWhy bio-individuality matters in nutrition and treatmentThe importance of sleep, blood sugar balance, nutrition, and stress managementNicole’s fertility fears after being diagnosed with PCOSHow she prepared her body before trying to conceiveHer experience becoming pregnant after years of worrying about fertilityHow severe stress and COVID triggered another health crisisLong COVID and mast cell activation syndrome (MCAS)The relationship between gut health, immune regulation, stress, and inflammationNicole’s personal experience with microdosed GLP-1 therapyThymosin alpha-1 and larazotide discussed during her recoveryEBO2 and its role in Nicole and McCall’s personal health journeysRegenerative medicine and stem cell therapies at PUR-FORMPUR-FORM’s newly launched MUSE cell offeringTherapeutic plasma exchange and health optimizationWhy finding one practitioner who truly listens can change your health journey Nicole’s Health Journey Started at 16 Nicole had been a healthy athlete when her health suddenly changed during her teenage years. Within months, she gained approximately 30 pounds, developed facial hair and irregular periods, struggled with severe fatigue, and experienced significant brain fog. After seeing multiple specialists, her mother took her to a trusted OB/GYN who decided to investigate her hormones and thyroid more deeply. Nicole was diagnosed with PCOS and, a year or two later, hypothyroidism. She was prescribed birth control and metformin. While these treatments addressed certain aspects of her condition, Nicole still struggled with her weight, inflammation, and energy. She knew she needed to look deeper. Discovering a Different Approach to Health A major turning point came after college when Nicole began working with a health coach. Instead of obsessively tracking calories and macros, she shifted her attention toward whole foods and began exploring how nutrition, stress, mindfulness, and emotional wellbeing influenced her health. She noticed her inflammation gradually improving. The experience ultimately inspired Nicole to study at the Institute for Integrative Nutrition, where she was introduced to a concept that became central to her approach to health: bio-individuality. What works for one person may not work for another. Nicole personally thrives living gluten-free, but she emphasizes that this does not mean everyone needs to eliminate gluten. Intermittent fasting may transform one person’s health while being completely wrong for someone else. McCall sees the same principle in thyroid care. There is no universally “best” thyroid medication or diet because each person’s physiology and needs are different. However, certain foundations remain important for almost everyone: whole-food nutrition, balanced blood sugar, quality sleep, movement, and stress management. PCOS, Fertility, and Preparing for Pregnancy When Nicole was diagnosed with PCOS as a teenager, she was told becoming pregnant might be difficult. The message stayed with her because she had always wanted to become a mother. Years later, when pregnancy became a priority, Nicole intentionally focused on creating the healthiest foundation she could. Working with her practitioners, she focused on lowering inflammation and supporting her overall health through personalized nutrition and supplementation. She discusses CoQ10 and fish oil, reducing sugar, eliminating alcohol, continuing her gluten-free lifestyle, temporarily removing dairy, and significantly reducing travel and stress. Perhaps most importantly, she gave herself permission to slow down. Nicole became pregnant after approximately three months of trying. She acknowledges that fertility is complex and that no lifestyle strategy can guarantee pregnancy. Still, her experience offers an encouraging perspective for women who fear that a PCOS diagnosis automatically means they will be unable to conceive. When Long COVID Triggered a New Health Crisis By 2023, Nicole felt healthier than she had in years. Then she contracted COVID during an intensely stressful period surrounding the launch of her business and her wedding. She became severely ill just days before getting married. After the acute infection passed, unusual symptoms remained. Nicole began experiencing significant histamine reactions, inflammation, weight changes, brain fog, fatigue, and irritability. Eventually, a practitioner recognized symptoms consistent with mast cell activation syndrome in the context of her post-viral health challenges. This became another turning point in how Nicole understood her body. Her immune system, gut health, inflammation, stress, and metabolic health were not operating independently. They were deeply interconnected. GLP-1s, Peptides, and Personalized Medicine Nicole worked with practitioners to explore different strategies during her recovery. She shares her personal experience with microdosed tirzepatide, a GLP-1-based medication, which she describes as an important tool for her own inflammation and metabolic health. She also discusses peptides, including thymosin alpha-1 in the context of immune support and larazotide in relation to gut barrier health. Gut health has been a recurring theme throughout Nicole’s health journey. She describes how periods of intense stress seemed to coincide with worsening inflammation and digestive health, reinforcing her belief that the body must be viewed as an interconnected system. The larger message is not that everyone needs the same medication, peptide, diet, or intervention. Personalized medicine means selecting tools according to the individual. What Is EBO2? McCall and Nicole also discuss EBO2, short for extracorporeal blood oxygenation and ozonation. Nicole explains that PUR-FORM offers EBO2 and trains other clinics in the protocol. The procedure involves circulating blood outside the body through a system involving filtration, oxygen, and ozone before returning it to the patient. Nicole shares that EBO2 has been part of her own health strategy outside of pregnancy. The topic is also deeply personal for McCall, who shares that she underwent EBO2 while struggling significantly with long COVID and credits the treatment as an important turning point in her own recovery. Their experiences lead to a broader conversation about the evolving field of regenerative medicine and the need to evaluate advanced therapies based on each patient’s individual circumstances. From Patient to Entrepreneur Nicole’s difficult health experiences eventually became part of her professional mission. She remembers working incredibly hard on her health while feeling as though her body simply would not respond. Years of inflammation, fatigue, weight struggles, and frustration also contributed to an unhealthy relationship with food at different points in her journey. Today, Nicole is running multiple businesses while preparing to become a mother. Her transformation inspired a commitment: if she could better understand her own health, she wanted to help other people avoid some of the confusion and frustration she experienced. That mission became part of the work behind PUR-FORM. Regenerative Medicine at PUR-FORM PUR-FORM is a comprehensive health optimization clinic based in Boca Raton, Florida. Nicole discusses working with orthopedic surgeon Dr. Joseph Purita and her family to expand access to integrative and regenerative therapies.
