In this week’s episode of the Quantum Lens Podcast, we welcome Sarah Kleiner, a board-certified quantum biology practitioner, mother, and wellness educator whose journey into holistic health began with a life-changing “red pill moment.”

Sarah shares her powerful personal story—how her daughter’s vaccine injury and her own struggles with fertility led her to question conventional medicine, experiment with diets from vegan to carnivore, and ultimately discover the transformative power of light, circadian biology, and quantum health.

From leptin and fertility, to the crucial role of sunlight, circadian rhythms, and seasonal living, Sarah unpacks how our modern environments disrupt hormones, metabolism, and even gut health—and offers practical ways to realign with nature’s rhythms.

✨ You’ll learn:

• Why leptin is more than a “satiety hormone”—it’s a master circadian signaling molecule for fertility, metabolism, and immune function.
• How light, not just diet, determines hormonal balance—including fertility, thyroid function, and weight regulation.
• The hidden links between sunlight, vitamin D, melatonin, and mitochondrial repair.
• How seasonal living—cold in winter, sun in summer, and circadian eating—restores health.

This conversation is a reminder that healing isn’t about restriction or perfection—it’s about reconnecting with light, cycles, and the wisdom of our biology.
