Editorial Policy

Updated April 2026.

The content on this site is written and reviewed by Sarah Jane Sandy, a functional nutritionist with nearly 20 years of experience specializing in reproductive health, fertility, and women’s hormonal health. This editorial policy outlines how content is created, sourced, and maintained — and what this site is and is not intended to provide.

Who creates the content on this site

All content is written or directly reviewed by Sarah Jane Sandy. Sarah holds a Master’s degree in Human Nutrition and is a certified Master Nutrition Therapist with a clinical focus on fertility, reproductive health, and hormonal balance. She has spent nearly two decades working with women navigating unexplained infertility, cycle irregularities, and conditions including PCOS, endometriosis, poor egg quality, and recurrent pregnancy loss.

Sarah’s approach is rooted in functional nutrition — investigating the underlying physiological drivers that conventional workups often miss. Her work is informed by ongoing engagement with peer-reviewed research, clinical lab interpretation, and direct client outcomes across hundreds of cases.

Content on this site reflects that clinical perspective. It is not produced by generalist writers, content agencies, or AI systems operating without subject-matter oversight.

How content is sourced and substantiated

Information published on this site is grounded in:

Peer-reviewed research published in scientific and medical journals
Clinical guidelines from recognized reproductive health and nutrition organizations
Sarah’s direct clinical experience working with fertility patients over nearly two decades
Established frameworks in functional and nutritional medicine

Where research is cited or referenced, Sarah links to or identifies original sources rather than secondary summaries. Claims are presented with appropriate nuance — emerging research is distinguished from established consensus, and areas of scientific debate are noted as such.

Content is not influenced by advertising, brand partnerships, or affiliate arrangements. Product or supplement mentions, when they appear, reflect Sarah’s clinical judgment and are disclosed transparently.

What this site is — and what it is not

The content on this site is intended for educational and informational purposes only. It does not constitute medical advice, diagnosis, or treatment. Reading content on this site does not create a practitioner-client relationship between you and Sarah Jane Sandy.

Sarah is a functional nutritionist, not a physician. The information here is designed to help you understand the nutritional and physiological factors that can affect fertility and hormonal health — not to replace the guidance of your OB-GYN, reproductive endocrinologist, or primary care provider.

If you are experiencing a medical concern, please consult a licensed healthcare provider. Nothing on this site should be used as a substitute for professional medical evaluation or care.

How content is reviewed and updated

Content on this site is reviewed on a regular basis to ensure accuracy and relevance. When new research substantially changes the understanding of a topic covered here, existing articles are updated and the revision date is noted.

Content that is time-sensitive — such as discussions of emerging research or evolving clinical guidelines — is flagged and prioritized for review. Older content that no longer reflects current evidence is revised or removed.

If you believe a piece of content contains an error or is outdated, you are welcome to contact Sarah directly at info@sarahjanesandy.com.

Transparency and conflicts of interest

Sarah operates The Fertility Code, a 12-week fertility program, and offers other professional services described on this site. Where content relates to her programs or services, that relationship is transparent — she is not a neutral third party with respect to those topics.

Her clinical recommendations and educational content are, however, based on her professional judgment and are not written to serve commercial interests at the expense of accuracy.

This site does not accept payment for editorial coverage, sponsored content placement, or product endorsements presented as independent recommendations.

A note on individual variation

Fertility and hormonal health are deeply individual. General information about nutrition, lab markers, egg quality, cycle health, and related topics is useful context — but it cannot account for the specifics of your history, labs, or clinical picture.

The goal of this content is to help you ask better questions, understand what may be missing from your current workup, and make more informed decisions alongside your care team. It is not a substitute for individualized clinical assessment.
