Whether you’re struggling with fertility, weight gain, or fatigue, there is another way.

I help PCOS, endometriosis, fertility prep, IVF support, postpartum recovery, perimenopause.

I use functional nutrition to help balance hormones and support fertility by addressing root causes—not just symptoms.

Nutrition and detox are foundational here: the nutrients we consume are the building blocks of a healthy body, and clearing toxins removes what often blocks optimal hormone function.

I create personalized plans based on your unique biochemistry and lifestyle, supporting gut health, blood sugar, detox pathways, and stress resilience to restore hormonal harmony naturally—without quick fixes or meds.

Conventional vs Functional Medicine Approach to Hormone Health

Conventional Approach

  • Treats symptoms with medications
  • One-size-fits-all protocols
  • Hormones tested only if symptoms are severe
  • Birth control or hormone replacement is the standard response
  • Focuses on isolated systems (e.g., reproductive only)
  • Labs often come back “normal” despite symptoms
  • Little to no dietary or lifestyle guidance
  • Reactive and short-term

Functional Medicine Approach

  • Identifies and addresses root causes
  • Personalized nutrition and lifestyle plans
  • Comprehensive hormone, gut, and nutrient assessments
  • Supports natural hormone balance through food, supplements, and detox
  • Looks at the whole body: gut, liver, thyroid, adrenals, and more
  • Values optimal ranges, not just “normal” on labs
  • Deep focus on nutrition, sleep, stress, movement, and mindset
  • Proactive and long-term healing strategy

Testimonials

"I’m pregnant! I know that you and I were not specifically working on my fertility, but I can only imagine that it had a huge impact - I got pregnant literally immediately!! We were super surprised, but are excited about it!"
- Erica T.
"I feel so fortunate to have found Shannon. She is warm, sincere, exceptionally knowledgable, and an absolute joy to work with. I have been on a personalized protocol for a couple months now and I am extremely pleased with my results so far. This woman has changed my life. I’m forever grateful."

"Shannon has been an incredible help to me through a long list of internal health issues. I saw many doctors and other nutritionists before her, but nothing was helping. I did her Reset Your Body Program, and it was very clear, organized, and manageable. She has been such a wonderful support, and adjusts my protocols as needed. Cannot thank Shannon enough for helping me heal!"
- Morgan B.
"I highly recommend working with Shannon South. I came to Shannon after years of TTC. She offered a new perspective with a focus on balanced nutrition. Her energy was so positive and optimistic (sometimes you just really need to have someone who believes in you. I believe this made all the difference for me! ). Shannon is thorough, she is patient, and she REALLY listens. It felt like Shannon was taking care of both my physical and my emotional well-being. I believe that it was with Shannon’s help that we were able to develop a few good-embryos that ultimately led to a successful IVF. We will be celebrating our son’s 1st birthday next week (oh, did I mention I’m in my late 40’s?)."
- Julia L.
“I got my period the other day and it actually seems pretty normal, which is incredibly exciting. I'm feeling good about my energy, skin and weight. All have really leveled out. My skin in particular looks beautiful - it’s glowing!“

"I’ve seen a huge improvement in my hives! I’m down to 1/4 Zyrtec every other day (from 4 Zyrtec per day) to take away the itching and hives. I’m also feeling less tired - my energy is good and I can eat more things like beans!! I couldn't tolerate eating them without extreme bloating and gas and now they don't bother me. I am so grateful for you. 🙏 My health is improving because of all you have done for me. Thank you so much. I truly appreciate you!"
- Monica V.
"I'm feeling great - probably the best l've felt in years!"

"I want to thank Shannon for her expertise and professionalism. About six months ago, I called in a panic because I was experiencing a kidney stone passing, and I was in excruciating pain. She told me several natural ways to subside the pain; I did so, and low and behold, it helped exceptionally well and fast. I was amazed at the results. Since then, I have been a believer in what she is offering. After that experience, I started consulting with her on my diet and started taking the recommended products. Since then, I have lost over 30 lbs and have more energy than ever before. I 100% would recommend her services and product to anyone looking to better their health."
