Is Cellular Energy the Key to Fertility Over 35?

In this insightful episode of Wellness by Designs, naturopath and nutritionist Belinda Kirkpatrick explores how supporting our cells' energy systems may hold the key to optimising fertility, particularly for women over 35. At the heart of the discussion is nicotinamide riboside (NR), a cutting-edge nutrient that acts as a precursor to NAD+, the essential molecule powering mitochondrial function, DNA repair and healthy gene expression. As NAD+ levels naturally decline with age—starting as early as our 30s—so too can egg and sperm quality. Belinda explains how NR effectively raises cellular NAD+ levels by easily crossing cell membranes, unlike other forms that must convert before entering cells.

Belinda shares practical guidance on how she uses NR in fertility treatment plans, highlighting typical doses ranging from 250 to 1000 mg daily depending on age and egg quality markers. Importantly, she explains that NR can be taken right up until egg collection during IVF without interfering with medications, making it a valuable option for those navigating assisted reproductive cycles. She also reveals her "top three" supplements for fertility support—NR, ubiquinol and NAC—describing how they work synergistically to enhance egg quality and overall reproductive health.

Beyond supplements, the episode dives into lifestyle strategies to support NAD+ levels naturally, from eating protein-rich foods that provide tryptophan precursors to understanding how sun exposure can deplete NAD+, while practices like infrared sauna therapy may help boost it. With her trademark blend of scientific detail and compassionate, practical advice, Belinda offers an evidence-informed roadmap for anyone seeking to optimise their reproductive potential—whether they're undergoing treatment or simply planning ahead. For those ready to explore how cellular health underpins fertility, this conversation provides an essential guide to the latest research and integrative strategies.
