Let’s be straight about this: there is no food, tea or supplement proven to increase progesterone production. Progesterone is a hormone made mainly by the corpus luteum — the structure left behind in the ovary after ovulation — and later in pregnancy by the placenta. Its levels rise and fall with your menstrual cycle, peaking about a week after ovulation. What you can do is support the conditions for healthy production: maintain a healthy weight, manage stress, get enough sleep, and get underlying conditions like PCOS or thyroid problems treated. If low progesterone is suspected, a GP can test your levels and discuss medical options.
Interest in “boosting progesterone” usually comes from a real concern: irregular periods, difficulty conceiving, PMS-like symptoms, or spotting between periods. Those deserve proper investigation rather than internet remedies. Understanding how progesterone is actually produced is the first step to knowing what can — and can’t — change it.
How progesterone production works
Each menstrual cycle, after an egg is released at ovulation, the empty follicle becomes the corpus luteum, which produces progesterone for about two weeks. Progesterone prepares the womb lining for a possible pregnancy; if none occurs, production falls and your period starts. This means regular ovulation is the engine of progesterone production — anything that disrupts ovulation (very low body weight, extreme exercise, significant stress, PCOS) reduces it.
What genuinely supports healthy levels
Maintain a healthy weight
Both underweight and overweight can disrupt ovulation and therefore progesterone. Fat tissue produces oestrogen, and excess oestrogen relative to progesterone is a common hormonal imbalance; being significantly underweight can stop ovulation altogether. Aim for a stable, healthy BMI rather than any crash diet.
Manage stress
Chronic stress raises cortisol, and the body prioritises cortisol production over sex hormones when under sustained strain — the pathways share raw materials. Regular exercise, proper downtime and addressing the sources of stress support the whole hormonal picture, progesterone included.
Sleep well
Hormone production follows circadian rhythms, and chronic short sleep disrupts the reproductive hormones. Consistently getting 7 to 9 hours supports normal cycling. Our guide on how much deep sleep you should get explains what quality sleep looks like in practice.
Eat for overall hormonal health
While no food raises progesterone directly, the building blocks of all steroid hormones come from dietary fats and cholesterol — extremely low-fat diets can impair hormone production. Include healthy fats (oily fish, nuts, olive oil, eggs), plenty of vegetables, and enough calories overall. B vitamins, magnesium and vitamin C are involved in the relevant pathways, so a varied diet covers you better than any single “hormone food.”
Treat underlying conditions
PCOS, thyroid disorders and high prolactin all interfere with ovulation and progesterone. If your cycles are irregular, very painful or absent, those need diagnosing — see our guide on how to relieve period cramps for cycle-related care, but don’t stop at symptom management if the pattern is abnormal.
What about “natural progesterone” creams?
Over-the-counter creams marketed as natural progesterone are widely sold, but their hormone content is unregulated and absorption through skin is unreliable — they are not a dependable way to raise levels, and some contain so little active ingredient that they do essentially nothing. Prescription progesterone (as tablets, pessaries, gels or injections) is a different matter: it is used in fertility treatment, to support early pregnancy in some cases, and as part of HRT. These are medical treatments with real effects and real side effects, decided with a doctor — not something to self-prescribe.
Getting tested
Progesterone is measured with a blood test, usually taken about seven days before your next period is due (day 21 in a textbook 28-day cycle) to catch the post-ovulation peak. NHS laboratories publish reference ranges — for example, South Tees NHS lists luteal-phase progesterone as roughly 3.5–67 nmol/L, illustrating how widely normal levels vary through the cycle. A single low reading needs interpreting alongside your cycle history, which is why testing is arranged through your GP rather than DIY kits.
Progesterone in fertility treatment
One context where progesterone is deliberately increased is fertility treatment. In IVF, the drugs used to stimulate the ovaries can impair the body’s own progesterone production, so clinics routinely prescribe progesterone supplements — as vaginal pessaries, gels or injections — from egg collection until a pregnancy test, and sometimes into early pregnancy. Progesterone is also part of some treatments for recurrent miscarriage, though the evidence there is more mixed and its use is decided case by case. This is prescription-only medicine with a specific purpose, which underlines the broader point: meaningful, lasting changes to progesterone levels come from medical treatment, not from foods or over-the-counter products.
FAQs
Can diet increase progesterone?
No food has been shown to raise progesterone levels directly. A balanced diet with adequate healthy fats and calories supports normal hormone production overall, but claims about specific “progesterone-boosting” foods aren’t backed by evidence.
What are the signs of low progesterone?
Possible signs include irregular or absent periods, spotting between periods, difficulty conceiving, and severe PMS. But these symptoms have many causes, so they need medical assessment rather than self-diagnosis.
Does stress lower progesterone?
Chronic stress can disrupt ovulation through its effects on the reproductive hormone axis, and since progesterone is produced after ovulation, sustained stress can indirectly lower it. Managing stress supports the whole cycle.
Can I take progesterone supplements without a prescription?
You shouldn’t. Prescription progesterone is used for specific medical reasons — fertility treatment, certain pregnancy support, HRT — and needs medical supervision. Unregulated creams and supplements are unreliable and can mask conditions that need proper treatment.
When should I see a GP about progesterone?
See your GP if your periods are irregular, very heavy or absent, if you’re struggling to conceive after a year of trying (or six months if you’re over 35), or if you have persistent spotting. They can arrange hormone blood tests timed to your cycle.
