Progesterone is often called the “calming hormone”, and for good reason. It supports restful sleep, stable mood, healthy cycles, implantation, and balanced estrogen activity. But here’s something many women aren’t told:
Progesterone is only made after ovulation.
So supporting progesterone isn’t about forcing it – it’s about creating the internal environment that allows ovulation and a strong luteal phase to thrive. There are so many natural ways to support this beautiful calming hormone – let’s dive into it!
1. Eat Sweet Potatoes for Beta-Carotene Support!
Here’s a little-known gem: beta-carotene intake has been associated with higher progesterone levels during the luteal phase.
Sweet potatoes are rich in beta-carotene, which the body converts into vitamin A, a nutrient essential for ovarian function and corpus luteum health (the structure that produces progesterone after ovulation).
A study in The Journal of Nutrition found that higher carotenoid levels were positively associated with progesterone concentrations in healthy women.
Roast them. Mash them. Add cinnamon and sea salt. Your ovaries will thank you.
2. Don’t Fear Cholesterol – It’s the Building Block
Progesterone is a steroid hormone, meaning it’s synthesized from cholesterol.
Very low-fat diets or chronically undereating can impair hormone production. Including whole-food sources of healthy fats like pastured eggs, wild salmon, olive oil, avocado. These foods provide the raw material your body needs for hormone synthesis.
Hormones are built, not borrowed.
3. Support Ovulation with Zinc-Rich Foods
No ovulation = no progesterone.
Zinc plays a key role in follicle development and the LH surge that triggers ovulation.³ Pumpkin seeds, oysters, grass-fed beef, and chickpeas are beautiful zinc sources.
Many women with short luteal phases are unknowingly low in zinc.
4. Lower Cortisol to Prevent “Progesterone Steal”
When the body is under chronic stress, it prioritizes cortisol production over reproductive hormones. The body prioritizes getting out of “danger” over reproductive function (kind of makes sense, right?).
Both cortisol and progesterone share the same precursor (pregnenolone). While “pregnenolone steal” is a simplified term, research clearly shows chronic stress disrupts luteal function and progesterone output.
Daily nervous system rituals matter:
- Morning sunlight
- Breathwork
- Gentle walks
- Saying no without apology
- Healthy boundaries
Safety + low stress supports ovulation.
5. Eat Vitamin C to Strengthen the Corpus Luteum
Vitamin C is concentrated in ovarian tissue and supports progesterone production in the luteal phase.
Clinical research has shown that vitamin C supplementation improved progesterone levels in women with luteal phase defects.
Add to your diet: citrus, kiwi, bell peppers, and broccoli.
Food first. Always.
6. Magnesium for Hormone Signaling
Magnesium helps regulate the hypothalamic-pituitary-ovarian (HPO) axis – the communication highway between your brain and ovaries.
Deficiency is associated with increased inflammation and stress signaling, both of which impair ovulation and progesterone balance.
Dark chocolate (85%+), leafy greens, almonds, and Epsom salt baths are gentle ways to replenish. You can also find our favorite magnesium supplements here.
7. Stabilize Blood Sugar (This One Is Huge)
Blood sugar instability raises insulin. Elevated insulin can disrupt ovulation, particularly in women with PCOS, lowering progesterone output.
Here’s some simple shifts to make:
- Pair carbs with protein. Aim for at least 30g of protein per meal.
- Eat within an hour of waking.
- Avoid coffee on an empty stomach.
- Don’t skip meals.
Hormones LOVE stability.
8. Sleep Before Midnight
Progesterone rises at night and supports GABA activity, your brain’s calming neurotransmitter.
Disruption of circadian rhythms is associated with menstrual irregularities and altered reproductive hormone secretion.
Aim for:
- Screens off by 8:00pm
- In bed by 10:00pm
- Morning light within 30 minutes of waking
9. Maintain a Nourished, Not Restricted, Body
Under-fueling and very low body fat reduce GnRH signaling from the brain, which suppresses ovulation and lowers progesterone production.
This is especially common in chronic dieters, high-intensity athletes, women under prolonged stress, and moms with young children who eat the “toddler diet”. Making yummy meals for their kids, but very little for themselves. Then eating any just the children’s leftovers. Moms, you deserve to nourish yourself well!
Progesterone thrives in a body that feels safe and fed.
A Gentle Reminder
Low progesterone isn’t a failure – it’s feedback.
Your body may be asking for:
- More nourishment
- Less stress
- Better sleep
- Balanced blood sugar
- Ovulatory support
Instead of forcing hormones, we create the conditions where they flourish. Because hormone balance is not about control – it’s about rhythm.
