A complete, science-backed plan to lower testosterone & cortisol, eliminate period pain, clear hormonal acne, and sync eating to every phase of your irregular cycle.
Your symptoms — irregular cycles, period pain, and hormonal acne — all point to the same root causes. Here's the science behind why food is so powerful.
Blunts morning cortisol spike, stabilises blood sugar all day. Aim for 25–35g protein at breakfast. This is arguably the single most impactful change you can make.
Clinical trials show spearmint tea lowers free testosterone by up to 30% in women with high androgens. Drink one cup morning, one afternoon. Replace one coffee with this.
Lignans in flax bind to testosterone receptors and assist excretion. Add to smoothies, yoghurt, or porridge. Ground is essential — whole seeds pass through undigested.
Broccoli, cauliflower, brussels sprouts and cabbage contain DIM — a compound that helps your liver process and clear excess androgens and oestrogens.
Sugar → insulin spike → ovarian testosterone production. This is the fastest route to acne flares. Replace with whole fruits, dates, or 85%+ dark chocolate.
Salmon, sardines, mackerel, or walnuts daily. Omega-3 directly reduces the prostaglandins responsible for period pain. Improvements are measurable within 2 cycles.
Grated raw carrot with olive oil and apple cider vinegar. The unique fibre in raw carrot binds excess oestrogen and testosterone in the gut, preventing reabsorption.
Dehydration is a cortisol stressor. Add a pinch of sea salt and squeeze of lemon. Proper hydration supports kidney filtration of excess hormones. Avoid alcohol entirely.
Every food either helps or hinders your hormone balance. Here's how key nutrients work.
Eat freely from the priority foods, include the supporting foods regularly, and minimise the foods to avoid.
DIM helps liver clear testosterone. Eat raw or lightly steamed to preserve indole-3-carbinol.
Lignans block testosterone receptors. 1 tbsp daily minimum. Ground form only.
Salmon, sardines, mackerel. High EPA/DHA reduces prostaglandins and inflammatory acne.
Healthy fats buffer cortisol. Rich in B5 which directly supports adrenal function.
High fibre binds excess hormones for excretion. Plant protein stabilises blood sugar.
Magnesium-rich, reduces cortisol. Satisfies sugar cravings without triggering insulin spikes.
Unique raw fibre binds and removes excess hormones from the gut. Grated with olive oil.
Complete protein + choline supports liver detox. Yolk contains vitamin D, B12, and selenium.
Anthocyanins reduce inflammation driving acne. Low-sugar — won't spike insulin.
As tea or fresh herb. Clinical evidence for lowering free testosterone. 2 cups daily.
Highest dietary source of zinc — critical for lowering testosterone and clearing acne.
Zinc + magnesium in one food. Rich in tryptophan which supports serotonin and mood.
Spinach, kale, rocket. Magnesium, iron, folate. Eat with vitamin C to boost iron absorption.
B6 for progesterone production. Complex carb — slow release glucose, no insulin spike.
Quercetin and allicin reduce inflammation and support liver detox pathways.
Anti-inflammatory polyphenols. Use as your primary cooking fat. Reduces cortisol-linked inflammation.
Plant-based omega-3 (ALA). Reduces inflammation and supports healthy cholesterol for hormone production.
Supports liver bile production. ACV reduces post-meal blood sugar spikes by up to 34% in studies.
2–3x/week for iron and zinc, especially around your period. Choose lean cuts.
1–2 daily for selenium — supports thyroid function which regulates all hormones.
Complete plant protein + fibre. Better than refined grains for blood sugar control.
High fibre, zinc, and B6. Hummus counts — great snack with raw veg.
Probiotic-rich for gut health and estrobolome support. Better tolerated than regular dairy.
EGCG reduces androgen activity and supports healthy insulin sensitivity. Replace afternoon coffee.
Collagen, glycine, and minerals. Supports gut lining integrity, foundational to hormone balance.
Beta-glucan fibre lowers inflammation. Always eat with protein and fat — never plain.
Natural melatonin precursors + anti-inflammatory anthocyanins. Especially good in the luteal phase.
Sauerkraut, kimchi, miso. Diversify gut bacteria and support proper hormone clearance.
Instant testosterone trigger via insulin. Replace with dark chocolate, berries, or dates. This is the #1 priority to cut.
IGF-1 in dairy strongly linked to acne. Increases prostaglandins that cause period pain. Try a 4-week elimination.
Raises cortisol, impairs liver detox, disrupts sleep. Even 1–2 drinks affects hormone balance for 2–3 days.
Sunflower, canola, corn, soybean oils are high in omega-6, promoting inflammation. Switch to olive oil or butter.
Rapid blood sugar spike → insulin → androgens. Replace with sourdough, sweet potato, oats, or quinoa.
Particularly bad on an empty stomach. Stimulates cortisol and depletes magnesium. Max 1–2 cups, never before breakfast.
Trans fats and additives drive systemic inflammation. The gut disruption alone worsens hormonal clearance.
Phytoestrogens in large quantities can disrupt oestrogen balance. Occasional edamame is fine; avoid soy isolate daily.
Even one skipped meal triggers a cortisol stress response. Especially damaging for those with irregular cycles.
Since your cycle is irregular, use physical signs — not day numbers — to identify your phase. Look for: bleeding (Menstrual), rising energy & clear CM (Follicular), slippery/stretchy CM & peak energy (Ovulatory), heavier/thicker CM + PMS signs (Luteal).
The pain you feel now was largely set up in your luteal phase by what you ate then. But what you eat NOW can dramatically shorten pain duration. Omega-3s, magnesium, ginger, and turmeric are your most powerful tools. Start with a warming ginger and turmeric broth on day 1.
EPA and DHA directly inhibit prostaglandin synthesis — the mechanism behind cramps. Aim for a 150g serving.
Replaces iron lost through bleeding. Haem iron absorbs 2.5× better than plant sources. Eat 2–3x this week.
Non-haem iron + magnesium for cramps. Eat with vitamin C (lemon) to enhance iron absorption significantly.
Plant iron + fibre to aid hormonal excretion and prevent constipation which worsens cramping.
Magnesium for muscle relaxation and cramp relief. Also rich in iron. 2–3 squares daily.
Glycine supports gut lining, reduces systemic inflammation. Warm and deeply nourishing for this phase.
As tea or in cooking. Ginger is as effective as ibuprofen for period pain in studies. Use daily this week.
Anti-inflammatory anthocyanins. Tart cherry juice reduces inflammatory markers within 24 hours.
Arachidonic acid in dairy increases prostaglandin production — directly worsening cramps. Avoid this entire phase.
Depletes magnesium, raises inflammation, disrupts sleep — all of which intensify pain. Strictly avoid.
Constricts blood vessels (worsening cramps) and depletes iron. Max 1 small coffee, after breakfast.
Traditional medicine consistently recommends warm, cooked foods during bleeding. Soups and stews over salads.
Blood sugar instability amplifies pain and fatigue during this already low-energy phase.
High omega-6 increases prostaglandin production — the opposite of what you need right now.
Boil fresh ginger slices for 10 min. Add lemon and raw honey. Multiple studies show it rivals ibuprofen for period pain relief when taken at the onset of bleeding.
Contains hippurate and glycine which relax uterine muscle spasms. Drink 2–3 cups daily during menstruation.
Tones the uterine muscles over time, reducing cramping intensity. Most effective when used consistently for 2+ cycles.
Continue 2 cups daily for testosterone. Can combine with ginger for a warming anti-androgen blend.
This is your metabolic sweet spot. Your liver and gut are your focus — help them clear androgens efficiently and you'll see improvements in acne within this cycle. Seed Cycling starts here: 1 tbsp each of ground flaxseed and pumpkin seeds daily from the start of this phase until ovulation.
Lignans block oestrogen and androgen receptors, reducing circulating testosterone. 1 tbsp in breakfast.
Zinc peak — critical for ovulation, acne reduction, and androgen metabolism. A small handful daily.
Choline in yolks is essential for liver Phase 2 detox. Also complete protein for blood sugar stability.
DIM and sulforaphane support both phases of liver detoxification of androgens. Eat lightly cooked.
Most effective in this phase. Grate 1 medium carrot, dress with olive oil and ACV. Eat with a meal.
Kefir, sauerkraut, kimchi. Support estrobolome — the gut bacteria that metabolise oestrogens and androgens.
Citrus supports bile production which is essential for hormone excretion through the digestive tract.
Vitamin E protects follicles from oxidative stress. B5 supports adrenal function and cortisol regulation.
Even though insulin sensitivity is better now, avoid white bread, rice, and pasta — these set a poor pattern.
Phytoestrogens during rising oestrogen can disrupt the natural hormonal cascade toward ovulation.
Impairs liver detox capacity just when you need it most. Even small amounts reduce hormonal clearance.
Omega-6 excess competes with omega-3 conversion, undermining the anti-inflammatory work you're doing.
Even with high energy, skipping meals raises cortisol which disrupts follicular development.
Ovulation is critical — without it, progesterone stays low and the next period is more painful. Anti-inflammatory eating now supports the corpus luteum (which produces progesterone after ovulation). Seed cycling shifts here: swap to 1 tbsp each ground sesame seeds and sunflower seeds daily.
Vitamin E and selenium support the corpus luteum post-ovulation to produce adequate progesterone.
Lignans and zinc — continue androgen-lowering support while fuelling progesterone production.
The richest source of zinc. A single serving covers your entire daily requirement. Critical for ovulation.
Peak digestion now — your body handles raw veg best. Load up on antioxidants to reduce skin inflammation.
Vitamin C aids non-haem iron absorption and supports collagen for skin healing post-acne.
Complete plant proteins with fibre. Quinoa contains manganese which supports progesterone synthesis.
Omega-3 and vitamin E. Reduce skin inflammation — testosterone spikes briefly here and can trigger spots.
Even as testosterone naturally rises to support libido, spearmint moderates the excess. Continue 2 cups.
Insulin spikes can disrupt the LH surge required for ovulation. Keep blood sugar stable today.
Skin may flare as testosterone peaks — dairy significantly worsens androgenic acne via the IGF-1 pathway.
Disrupts oestrogen metabolism. Even moderate drinking can suppress ovulation in some women.
Seed oils, processed foods, and fried food increase systemic inflammation that impairs ovarian function.
This is the most dietary-critical phase for your goals. High cortisol here crushes progesterone production — so stress management is as important as food. Honour hunger — your metabolism is 5–10% faster. Complex carbs at dinner support serotonin and help you sleep, which keeps cortisol from spiking overnight. Never restrict calories in this phase.
B6 (vitamin B6) is essential for progesterone production and reduces PMS symptoms by up to 50% in studies.
B6, magnesium, and tryptophan — a triple hit for mood, cramp prevention, and cortisol regulation.
What you eat now determines prostaglandin levels next week. Front-loading omega-3 is the most evidence-based dietary period pain intervention available.
Cholesterol from healthy fats is the literal building block of progesterone. Low-fat diets during this phase worsen hormonal outcomes.
Magnesium cravings are real and legitimate — 70–85% dark chocolate delivers magnesium without the insulin spike.
Continue seed cycling. Sesame lignans support progesterone, sunflower vitamin E supports corpus luteum.
Chamomile reduces anxiety and cortisol. Ashwagandha is an adaptogen shown to lower cortisol by 27% in controlled trials.
Zinc + selenium combo supports progesterone synthesis and prevents the luteal-phase acne flare.
Worsens water retention and bloating. Use herbs and lemon instead of salt for flavour.
Depletes progesterone and B vitamins. Even 1–2 drinks measurably worsens PMS symptoms.
Blood sugar crashes in this phase trigger cortisol which cannibalises progesterone. Keep blood sugar absolutely stable.
Especially in the week before your period — caffeine raises cortisol and can worsen breast tenderness and anxiety.
Calorie restriction is a major stressor that raises cortisol and crashes progesterone. Eat nourishing, filling meals.
Pre-period acne flare is heavily influenced by dairy/IGF-1. Eliminating dairy in this phase has the most visible effect.

Food comes first — always. These supplements fill the gaps and accelerate results. Introduce one at a time. Discuss with your GP before starting, especially if on medication.
The most important supplement for your goals. Magnesium glycinate (not oxide) is highly absorbable and doesn't cause digestive upset. Reduces cortisol, relaxes uterine muscle cramps, improves sleep quality, and is depleted by stress and caffeine. Most women with period pain are deficient.
Form matters — avoid zinc oxide (poorly absorbed). Zinc directly inhibits 5-alpha-reductase, the enzyme that converts testosterone to the more potent DHT responsible for acne. Also essential for ovulation and progesterone production. Take with food to avoid nausea, separately from iron supplements.
The most evidence-based intervention for period pain. A 2012 study found omega-3 significantly more effective than ibuprofen for dysmenorrhoea. Also reduces inflammatory acne and supports the healthy progesterone-to-oestrogen ratio. Choose pharmaceutical-grade fish oil with high EPA content, third-party tested for purity.
Over 70% of people in northern latitudes are deficient. Vitamin D acts as a hormone regulator — low levels are strongly associated with PCOS, high androgens, and severe period pain. K2 ensures calcium goes to bones, not arteries. Get blood tested first to determine your correct dose; optimal level is 60–80 ng/mL.
The most research-backed supplement for irregular cycles and elevated androgens, particularly when insulin resistance is a factor. Improves insulin sensitivity in the ovaries, reducing testosterone production at source. Studies show significant improvements in cycle regularity within 3–6 months. Often the game-changer for irregular cycles with high androgens.
The most studied adaptogen for cortisol reduction. A 2019 double-blind RCT found KSM-66 ashwagandha reduced cortisol by 27.9% versus placebo over 60 days, while also improving sleep quality and reducing food cravings. Choose KSM-66 or Sensoril — not generic ashwagandha root powder.
Works on the pituitary gland to support LH production which stimulates progesterone release. Most effective for luteal phase defect and PMS. Takes 3–6 months of consistent use to show full effect. Do NOT take if you are on hormonal contraception or have hormone-sensitive conditions. Discuss with GP first.
If you can't drink spearmint tea twice daily, a standardised spearmint extract provides equivalent anti-androgen effects. The active compound rosmarinic acid has been shown in two clinical trials to significantly lower free and total testosterone in women with elevated androgens. One of few plant-based supplements with direct clinical evidence for testosterone reduction in women.
Vitex chasteberry · Lemon water / ACV water. Taking vitex before breakfast ensures best pituitary absorption.
Vitamin D3 + K2 (with fat) · Myo-Inositol (half dose) · Omega-3 (half dose). Fat-soluble vitamins need dietary fat for absorption.
Zinc picolinate · Omega-3 (second half) · Myo-Inositol (second half). Zinc with food prevents nausea. Never take zinc and iron at the same time.
Magnesium glycinate · Ashwagandha KSM-66. Evening timing matches natural cortisol rhythm and maximises sleep quality benefits.
Diet is foundational, but these lifestyle factors can make or break your hormonal health. Cortisol is particularly sensitive to lifestyle — and cortisol drives both testosterone and period pain.
Without predictable day numbers, physical signs become your map. Learning to read these signals means you can eat exactly right for each phase — even when your cycle is unpredictable.
Take your temperature every morning before getting up using a BBT thermometer. A sustained rise of 0.2°C confirms ovulation occurred. Apps: Kindara, Natural Cycles, or Clue. This tells you whether you're ovulating — essential to know.
Check daily. Note: dry / sticky / creamy / watery / egg-white / absent. This is the most reliable indicator of cycle phase for irregular cycles. Peak fertile mucus = ovulatory phase. Returns to dry/absent after ovulation.
Rate 1–10 daily. Over time, patterns emerge that help identify your phases even with irregular timing. Low + tired = menstrual. Rising = follicular. Peak = ovulatory. Heavier + wanting comfort = luteal.
Note acne location: chin/jaw = hormonal/androgen excess. Forehead = gut/digestive. Cheeks = liver or dairy. Track alongside your phase and what you ate — patterns usually become clear within 2 cycles.
Track: flow (light/medium/heavy), colour (bright red = healthy, dark brown = low progesterone), clots (large clots = possible oestrogen dominance), and pain (1–10). You should see improvement by cycle 2–3 of this plan.
Note when you hit your key daily habits: ground flaxseed ✓, spearmint tea ✓, omega-3 ✓, cruciferous veg ✓. Even simple tick-box tracking dramatically improves adherence and helps you see what correlates with better days.
