Foods That Support Progesterone Levels Naturally

A common question in women's health: "What foods increase progesterone?" The answer is nuanced — no food directly contains human progesterone. But specific nutrients are essential for your body to produce it, and a diet deficient in these nutrients will compromise your progesterone output cycle after cycle.

How Your Body Makes Progesterone

After ovulation, the follicle that released the egg transforms into the corpus luteum — a temporary structure that produces progesterone for the next 12–14 days. The corpus luteum needs cholesterol, zinc, vitamin B6, vitamin C, and magnesium to produce adequate progesterone. Without these raw materials, production suffers even when the corpus luteum forms correctly.

Key Nutrients for Progesterone Production

Zinc

Zinc is essential for the development of follicles (before ovulation) and for supporting the corpus luteum (after ovulation). Low zinc directly impairs progesterone secretion.

Best sources: Oysters (highest by far), beef, lamb, pumpkin seeds, chickpeas, cashews, yogurt

Vitamin B6 (Pyridoxine)

Vitamin B6 supports progesterone production and is also essential for converting tryptophan to serotonin — explaining why B6 deficiency worsens both low progesterone symptoms and mood-related PMS simultaneously.

Best sources: Turkey, chicken, tuna, salmon, banana, potato, sunflower seeds, pistachios

Vitamin C

The corpus luteum is one of the highest vitamin C-containing tissues in the body. Studies show that vitamin C supplementation (750mg/day) can increase mid-luteal progesterone by up to 77% in women with luteal phase defects.

Best sources: Bell peppers (red highest), kiwi, strawberries, citrus, broccoli, kale

Magnesium

Magnesium supports the entire hormonal cascade by reducing cortisol (which competes with progesterone), regulating insulin, and supporting the conversion of pregnenolone to progesterone rather than cortisol.

Best sources: Pumpkin seeds, dark chocolate (70%+), spinach, almonds, black beans, avocado

Healthy Fats and Cholesterol

Progesterone is a steroid hormone derived from cholesterol. Very low-fat diets or low-cholesterol diets can reduce the raw material available for progesterone synthesis. Include egg yolks, avocado, olive oil, fatty fish, nuts, and full-fat dairy.

Foods That Harm Progesterone

• Excess caffeine: Linked to lower luteal phase progesterone in observational studies
• Alcohol: Impairs liver function, disrupting progesterone metabolism
• Refined sugar and processed carbohydrates: Drive insulin resistance and cortisol, both of which reduce progesterone
• Very low calorie diets: Undereating suppresses ovulation — no ovulation means no corpus luteum, no progesterone

Phytoestrogens: A Nuance

Some plant foods — particularly soy and flaxseeds — contain phytoestrogens that interact with estrogen receptors. There is concern that these might lower progesterone relatively by boosting estrogenic activity. In typical dietary amounts, the evidence suggests phytoestrogens are neutral to beneficial for most women. However, if you have significant estrogen dominance, very high phytoestrogen intake alongside already-low progesterone may not be ideal.

Vitex (Chasteberry): The Herbal Option

Vitex agnus-castus is an herb with clinical evidence for supporting progesterone levels by stimulating LH secretion from the pituitary, which in turn supports corpus luteum function. Multiple randomized trials show improvements in luteal phase length, pre-period spotting, and PMS symptoms. It takes 3–6 months to show full effect. It is not a food but is a dietary supplement worth knowing about.
