Key wellness strategies & takeaways (fertility supplements)

Core mindset: supplements are “tools,” not magic

  • Use supplements only as support for the body—not as a replacement for foundational health.
  • The goal is the right therapy for the right person at the right time, supported by testing and sequencing.

The “supplement hamster wheel” problem (what to avoid)

  • People buy supplements based on influencer/friend recommendations.
  • They try multiple products, may feel “a bit better,” then keep stacking them indefinitely.
  • Result: overwhelm, unclear cause/effect, expensive protocols, and still no pregnancy progress.

Four major mistakes seen in practice

  • Treating supplements as the main strategy instead of support.
  • Assuming more = better (more products, higher doses, advanced stacked therapies).
  • Following research/influencer advice without context (no individual testing; small or unclear studies; timing/dosing may not fit your cycle or genetics).
  • Chasing “cutting-edge” tools (e.g., peptides/NAD) before basics are handled (bloodwork, electrolytes/hydration, gut testing, etc.).

The “3 filters” framework: Right therapy / Right person / Right time

1) Right therapy

Check whether the supplement has a clear intention and job, for example:

  • Does it match a specific problem in labs or symptoms?
  • How will you track whether it’s working? (testing, data, symptoms)
  • Is it appropriate for your current phase (preparing vs conceiving vs detox/support)?

2) Right person

Match supplement forms/doses to your individual biology:

  • Consider genetics (not just one gene like MTHFR—many methylation-related genes may matter).
  • Assess terrain such as:
    • methylation/detox pathways
    • microbiome/gut function
    • ability to absorb nutrients (digestion, inflammation, “leaky gut” concerns)
  • Adjust for interactions:
    • Example logic: if someone has infections/parasitic load + low iron/ferritin, dosing iron could potentially worsen inflammation—so root causes must be addressed first.

3) Right time

Use supplements in the correct sequence and life stage:

  • Timing matters for menstrual cycle phase and fertility journey stage (trying naturally vs investigating infertility vs IVF/IUI prep).
  • In practice, protocols are often changed every 4–6 weeks (sometimes sooner) rather than kept forever.

How to choose supplements: 3 practical rules

1) Do the basics first (“before the bottles”)

Foundational priorities:

  • Nutrition (stable blood sugar, adequate protein, fiber)
  • Hydration + minerals
  • Sleep
  • Stress/nervous system work
  • Clean up environmental toxins/endocrine disruptors (she emphasizes sunscreen/cosmetics/perfumes as potential exposures)

Goal: create an environment where the body can thrive; supplements can’t compensate for a broken foundation.

2) Test before you supplement

  • Supplements are poorly regulated; quality and activity vary widely.
  • Invest in testing before spending on multiple products.
  • Testing helps prioritize root cause, not symptom-chasing.
  • Examples of root-cause logic:
    • Poor sleep may be driven by pain/inflammation, autoimmune issues, nutrient deficiencies, infections, or heavy metals—not just “need melatonin.”
    • High LDL can signal inflammation/liver/mitochondrial issues depending on the full context.

3) Use high-quality, verified supplements (not “off the shelf”)

  • Not all brands/sources deliver the same active forms or outcomes.
  • Even within reputable brands, formulations and ingredients matter (she cites examples like):
    • NAC varying by manufacturer
    • curcumin formulation differences and additives like soy lecithin affecting estrogen-related considerations
  • Track results using meaningful data/labs (and optionally wearables/monitoring tools like CGMs or rings).

Symptom support vs root-cause work

  • Supplements can be used temporarily to improve symptoms while you address root causes (e.g., to help sleep so the nervous system can settle while deeper causes are treated).
  • Key principle: the intention should be clear—don’t turn symptom relief into an endless stack.

Patient sequencing warning: “right supplement, wrong timing” can backfire

  • Example: women with endometriosis used estrogen-clearance–supporting supplements long-term at high doses, and ended up with signs consistent with early menopause (dryness, hair changes, libido changes, weak ovulation).
  • Lesson: estrogen dominance/stagnant estrogen must be understood with context and testing; assumptions can create harm.
