What to Eat During Your Period

By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham

What you eat during your period has a direct, measurable effect on how heavy the flow is, how much it hurts, how tired you feel, and how steady your mood remains. The right foods reduce cramping, support blood replenishment, ease fatigue and stabilise mood — the wrong ones drive inflammation, intensify pain, worsen bloating and prolong the recovery week. Chinese food therapy has 2,000 years of accumulated clinical observation about what the body needs across each phase of the menstrual cycle, and modern nutritional research increasingly validates these principles. This page is a practical, evidence-based guide to what to eat during menstruation, what to avoid, and how to extend the approach across the rest of the cycle for longer-term improvement.

Why diet matters during your period

Three things happen during menstruation that diet directly influences:

• Blood loss — typically 30-80 mL per period; over a year that's 400-1,000 mL of blood replaced from dietary iron, B12, folate and protein.
• Prostaglandin release — drives uterine cramping and inflammation; an anti-inflammatory diet meaningfully reduces pain.
• Hormonal flux — oestrogen and progesterone are at their lowest, which affects mood, sleep, energy and gut function. Stable blood sugar and adequate nutrient intake buffer the impact.

What the body needs

• Iron — to replace what's lost.
• Vitamin B12, B6 and folate — for red blood cell production and methylation.
• Magnesium — uterine smooth muscle relaxation; reduces cramping.
• Omega-3 (EPA/DHA) — reduces prostaglandin-driven inflammation.
• Protein — building blocks for blood and tissue.
• Adequate calories — undereating during periods makes recovery slow.
• Warmth — body temperature drops slightly; warm food supports circulation.
• Hydration — both for cramping and bowel regularity.

Foods to eat

• Iron-rich foods — red meat (especially liver), lamb, oysters, sardines, dark leafy greens, lentils, beans, pumpkin seeds. Combine with vitamin C (citrus, peppers, tomatoes) to boost absorption.
• Warming, blood-building foods (TCM) — black sesame seeds, red dates (Da Zao), beetroot, black beans, bone broth, slow-cooked meats. Particularly important in the days after the period when blood is at its lowest.
• Anti-inflammatory foods — oily fish (salmon, mackerel, sardines), walnuts, flaxseed, chia seeds, olive oil. Provide omega-3 to reduce uterine prostaglandins. RCT evidence shows omega-3 reduces dysmenorrhoea pain.
• Warming spices — ginger, cinnamon, turmeric, fennel, black pepper, cardamom. Ginger has RCT evidence for reducing period pain comparable to ibuprofen at 250 mg three times daily.
• Magnesium-rich foods — dark chocolate (70%+), pumpkin seeds, almonds, cashews, dark leafy greens, avocado.
• Warming drinks — fresh ginger tea, red date and goji berry tea, peppermint tea, chamomile tea.
• Cooked vegetables — particularly root vegetables, squash, sweet potato, carrots; soups and stews are ideal.
• Eggs — protein, B12, choline, iron.
• Adequate protein at every meal — supports blood building.
• Whole grains — oats, brown rice, quinoa, millet (warming).
• Berries and pomegranate — antioxidant; blood-building in TCM.
• Bone broth — classical postpartum/post-period TCM food; rich in collagen and minerals.

Foods to avoid

• Cold and raw foods — ice cream, cold drinks, raw salads, chilled smoothies. In TCM these "cool the uterus" and worsen cramping. Many women instinctively know this — the period is when most women crave warm cooked food.
• Alcohol — disrupts hormones, increases inflammation, impairs liver clearance of oestrogen, depletes B vitamins, dehydrates, worsens sleep and next-day mood.
• Excessive caffeine — constricts blood vessels, increases anxiety and pelvic tension, depletes magnesium. Limit to 1-2 cups daily; avoid late afternoon and evening.
• Refined sugar and ultra-processed food — drives inflammation and blood sugar instability that worsens mood.
• Trans fats — increase inflammatory prostaglandins.
• Excess salt — worsens fluid retention and bloating.
• Carbonated drinks — worsen bloating.
• Excess dairy in TCM phlegm-damp types — particularly cold milk; can worsen heavy clotted flow in some women.
• Spicy hot foods (in heat-pattern types) — can worsen heavy hot flow and irritability.
• Skipping meals — drops blood sugar, worsens mood and cramping.

The warming-foods principle

The single most consistent piece of TCM dietary advice for periods is: keep the digestive system warm. Cold food and drinks (and to a lesser extent raw foods) cause the uterine vessels to constrict, slowing the smooth flow of blood. The result is more cramping, more clotting, and slower recovery. Warming foods — soups, stews, ginger tea, slow-cooked meals, root vegetables, warming spices — support smooth menstrual flow and reduce pain.

This is why many women instinctively crave warm comfort food on their period (and why ice cream cravings, often hormonal in origin, can paradoxically worsen the very pain they crave to soothe).

Supplements that help

• Magnesium glycinate (300-400 mg) — strong evidence for reducing period pain. Take from a few days before the period through to day 2-3.
• Vitamin B6 (P5P, 25-50 mg) — supports premenstrual mood and serotonin.
• Omega-3 (EPA-rich, 1-2 g) — anti-inflammatory; reduces dysmenorrhoea.
• Iron (only with confirmed low ferritin) — replaces menstrual losses.
• Vitamin D3 — deficiency worsens period pain.
• Vitamin E (200-400 IU) — RCT evidence for reducing dysmenorrhoea.
• Curcumin — anti-inflammatory.
• Ginger extract (250 mg three times daily) — RCT evidence comparable to ibuprofen for period pain.
• Vitex (chasteberry, 20-40 mg) — for premenstrual symptoms; not in PCOS without specialist input.
• Zinc — supports cycle health; reduces dysmenorrhoea in some studies.

Eating for your TCM pattern

• Cold-stasis (cramping, dark clots, relieved by warmth) — emphasise warming foods, ginger, cinnamon, lamb, bone broth; strictly avoid cold and raw.
• Liver qi stagnation (PMS, breast tenderness, irritability, mood swings) — light, easy-to-digest meals; reduce alcohol; gentle Liver-supportive foods like beetroot, dandelion greens, lemon water.
• Blood deficiency (scant pale flow, dizziness, fatigue, poor sleep) — strong emphasis on iron-rich and blood-building foods; bone broth daily.
• Damp-heat (heavy hot flow with strong odour, pelvic heaviness) — reduce dairy, alcohol, spicy hot food; emphasise green leafy vegetables, mung beans, mild herbs.
• Spleen qi deficiency (heavy flow with fatigue, loose stools) — warm cooked foods, no cold or raw; reduce sugar; include white rice, sweet potato, chicken, ginger.
• Kidney deficiency (low energy, low backache, low libido) — black foods (black sesame, black beans, black rice), walnuts, slow-cooked meat.

Eating across the four cycle phases

The TCM cycle-phase approach extends the eating principles across the whole month:

• Menstrual phase (days 1-5) — warming, gently moving, blood-replenishing foods. Soups, stews, ginger tea, root vegetables, dark leafy greens, oily fish, dark chocolate.
• Follicular phase (days 6-13) — building yin and blood. Eggs, fish, beans, leafy greens, sprouts, fermented foods, berries, pomegranate.
• Ovulation (days 14-16) — supporting qi-moving and yang-rising. Light proteins, raw or lightly cooked vegetables, turmeric, garlic, ginger.
• Luteal phase (days 17-28) — supporting Kidney yang and Spleen qi for the corpus luteum. Slow-cooked meats, bone broth, warming spices, root vegetables, sweet potato, walnuts.

Special cases

• Postnatal first periods — particularly important to eat blood-building, warming, slow-cooked foods. Bone broth daily for first 6 weeks.
• Heavy periods — replace iron aggressively; avoid raw food during the heaviest days; pause strong blood-movers (don't eat huge amounts of beetroot).
• Endometriosis — anti-inflammatory diet; consider gluten-free and dairy-free trials; low-FODMAP for endo belly.
• PCOS periods — whenever they come, focus on insulin-sensitising foods: protein, healthy fats, low-GI carbs.
• Perimenopause — particularly important to maintain stable blood sugar and adequate protein.
• Athletes — eat enough; under-eating during periods worsens fatigue and recovery.
• Vegetarians/vegans — pay particular attention to iron (with vitamin C), B12 (methylcobalamin), zinc, protein, omega-3 (algae-based DHA).

Sample meal ideas

• Breakfast: warm porridge with cinnamon, walnuts, red dates and a drizzle of honey; or scrambled eggs with sautéed spinach and tomato.
• Mid-morning: ginger tea with a square of dark chocolate; or red date and goji berry tea.
• Lunch: chicken and vegetable soup with brown rice; or beef bone broth with sweet potato and greens; or salmon with quinoa and roasted vegetables.
• Mid-afternoon: apple with almond butter; or bone broth in a mug; or pumpkin seeds and a few squares of dark chocolate.
• Dinner: slow-cooked lamb stew with root vegetables; or stir-fried prawns with ginger, garlic and greens; or lentil and vegetable curry with brown rice.
• Evening: chamomile tea or warm milk (if tolerated) with a teaspoon of honey and a pinch of nutmeg.

Frequently asked questions

Should I really avoid cold drinks during my period?

Many women find their cramping is worse if they have iced drinks during the period. The TCM principle is that cold causes uterine vessels to constrict, slowing flow and worsening pain. Try warm drinks for one cycle and notice the difference.

Does dark chocolate really help period pain?

Yes — its magnesium content is genuinely useful for reducing uterine cramping. 70%+ cocoa is best; 30-50 g is enough. Don't use it as a sugar excuse.

Should I take iron supplements during my period?

Only if your ferritin is low. Many menstruating women have suboptimal ferritin even with no anaemia — get tested. Take with vitamin C, away from tea/coffee.

Is the period a good time for a juice cleanse?

No. Juice cleanses are typically cold, raw, low-protein and low-calorie — the opposite of what the period needs. Save it for another time of the month if you want one (and consider whether they're useful at all).

Why do I crave chocolate and ice cream during my period?

Chocolate cravings are typically magnesium-related — go for dark chocolate. Ice cream cravings are hormonal but mostly comfort-driven; warm milk with honey often satisfies the same craving without the cold.

Should I avoid intermittent fasting during my period?

Yes — periods need adequate calories. Modest 12-hour overnight fasting is fine; aggressive 16+ hour fasting can worsen fatigue and prolong cycle pain.

Is dairy bad for periods?

Depends on the pattern. In phlegm-damp or damp-heat types, dairy can worsen heavy clotted flow. Some women improve markedly off dairy for several cycles. Try a 6-week trial off cow's milk dairy and see.
