You’ve taken an important step in your fertility journey with IUI, and now the wait begins. While you can’t speed up time, you can nourish your body with foods that support implantation, balance hormones, and give your little embryo the best chance to thrive.
Nutrition and IUI success: How diet can make a difference
Your diet can have a powerful impact on reproductive health and fertility treatment outcomes. The foods you eat influence key factors such as hormone production, ovulation, egg and sperm quality, and the receptivity of your uterine lining. After an intrauterine insemination (IUI) procedure, prioritising nutrient-dense, fertility-friendly foods may help support:
Successful embryo implantation
Stable hormonal balance
A thick, healthy uterine lining
Optimal egg and embryo development
After IUI treatment, it's important to eat well to support your reproductive system and overall health. This helps give your body the best possible foundation for conception and a healthy pregnancy.
What to eat after IUI to boost your chances of success?
After IUI, fuelling your body with fertility-friendly foods rich in essential nutrients can help support embryo implantation, hormone balance, and early pregnancy development. Here’s a breakdown of the key food groups to focus on:
Protein-rich foods
Recommended choices:
Lean poultry, low-mercury fish, and eggs
Plant proteins can be found in foods like lentils, chickpeas, black beans and quinoa.
Greek yoghurt and cottage cheese
Why they matter: Protein plays a vital role in cell repair, hormone production, and building a healthy endometrial lining, which is essential for successful implantation. You should aim for 60–80 g of protein daily to meet your body’s needs.
Omega-3 fatty acids
Recommended sources:
Fatty fish like salmon, sardines, and trout
Walnuts, chia seeds, and flaxseeds
Fish oil or algae oil supplements (recommend to consult your doctor)
Why they matter: Omega-3s help regulate reproductive hormones, reduce inflammation, and improve both egg quality and uterine blood flow. These are all key factors for implantation success.
Complex carbohydrates
Recommended choices:
Brown rice, quinoa, oats, sweet potatoes, and whole-grain bread
Beans and legumes
Why they matter: These slow-digesting carbs keep blood sugar levels steady, supporting hormone function and ovulation. This is especially important for women with PCOS or insulin resistance.
Hydration
Recommendations:
Drink 8–10 glasses (around 2–2.5 L) of water daily
Include coconut water or herbal teas like ginger, nettle, or raspberry leaf (in moderation)
Why it matters: Staying well-hydrated maintains healthy cervical mucus, promotes uterine blood flow, and ensures nutrients are delivered to the developing embryo.
Iron-rich foods
Recommended sources:
Lean red meat, liver (in moderation), spinach, lentils, and fortified cereals
Pair with vitamin C-rich foods (e.g., citrus fruits) to boost absorption
Why they matter: Iron helps prevent anaemia and supports a well-oxygenated uterine lining, creating a favourable environment for implantation.
Calcium-rich foods
Recommended sources:
Dairy products: milk, yoghurt, and cheese
Non-dairy options: broccoli, kale, almonds, and fortified plant-based milks
Why they matter: Calcium supports reproductive and nervous system function, aids hormone secretion, and contributes to the embryo’s bone development.
Herbal teas and supplements
Recommended sources:
Nettle tea: High in iron, calcium, and magnesium
Raspberry leaf tea: Traditionally used to tone the uterus (best before ovulation)
Supplements: Prenatal vitamins with folic acid, vitamin D, omega-3, and CoQ10 (only with medical guidance)
Remember to always check with your fertility specialist or nutritionist before introducing new herbs or supplements.
Fruits and vegetables
Best picks:
Brightly coloured produce like carrots, sweet peppers, berries, oranges, and spinach
Avocados for healthy fats and folate
Why they matter: Packed with antioxidants, vitamins, and fibre, fruits and vegetables support hormonal health, protect reproductive cells, and help the body eliminate toxins.

How do these foods support IUI success?
The nutrients in fertility-friendly foods work together to create an optimal environment for implantation and early pregnancy. Here’s how each one benefits your reproductive health after IUI:
Nutrient / Food | Fertility benefit |
Protein | Helps build a healthy endometrial lining, supports hormone production, and aids in cellular repair. |
Omega-3 fatty acids | Enhances egg quality, reduces inflammation, and improves blood flow to the uterus, boosting implantation potential. |
Iron | Supports efficient oxygen delivery to the uterus and developing embryo, reducing the risk of anaemia. |
Calcium | Supports hormone signalling, reproductive system function, and foetal bone formation. |
Complex carbohydrates | Maintain steady blood sugar levels, supporting hormone balance and ovulation. |
Antioxidants | Protect reproductive cells from oxidative stress and DNA damage. |
Water | Keeps cervical mucus healthy and aids nutrient transport to reproductive tissues. |
Folic acid | Essential for early foetal development and prevention of neural tube defects. |

FAQ
Why are leafy green vegetables recommended after IUI?
Leafy greens are rich in folate, iron, and antioxidants that help support a healthy uterus and early embryo development. They also promote good blood flow to the reproductive organs and may help reduce inflammation in the body.
Should I include dairy products in my diet after IUI?
Dairy products, especially full-fat options, provide calcium, vitamin D, and probiotics, which support overall reproductive health. Some studies suggest full-fat dairy may help regulate ovulation. If you are lactose intolerant, opt for fortified plant-based milks such as almond, soy, or oat milk. Whenever possible, choose organic and hormone-free sources.
Are nuts and seeds good to eat after IUI?
Yes. Nuts and seeds such as almonds, sunflower seeds, pumpkin seeds, and walnuts are rich in zinc, selenium, vitamin E, and healthy fats. These nutrients are important for hormone balance and supporting egg and embryo quality.
What fruits should I limit after IUI?
Limit unripe papaya (may trigger uterine contractions), large amounts of pineapple core (high in bromelain), and high-sugar fruits like mangoes or lychees. Wash all fruits well and choose organic when possible.
Should I take supplements after IUI?
A prenatal vitamin is often recommended to support overall reproductive health. Depending on your individual needs, your doctor may also suggest the following supplements:
CoQ10: for supporting egg health
Vitamin D: for reproductive system function
Inositol: for women with PCOS
Omega-3s: for overall reproductive health
Avoid starting any new supplements without consulting your doctor or fertility specialist.
How do healthy fats contribute to reproductive health after IUI?
Healthy fats help regulate oestrogen and progesterone, support cell membrane function, and provide anti-inflammatory benefits. Good sources include avocados, olive oil, nuts, seeds, and fatty fish (low in mercury).
What foods should I avoid after IUI?
You should limit or avoid:
Unripe papaya and excess pineapple core, as they may affect your uterine health.
High-mercury fish, such as swordfish, king mackerel, and shark.
Processed foods or high-sugar foods, as they can cause blood sugar spikes.
Excess caffeine and aim to keep your daily caffeine intake below 200 mg, as high intake may disrupt hormone levels, potentially impacting implantation.
Alcohol and tobacco, as they can affect your reproductive health.
What lifestyle changes, besides diet, can support reproductive health after IUI?
In addition to a balanced diet, these lifestyle habits may help maintain overall well-being:
Exercise moderately:
Activities like walking, yoga, or swimming can help balance hormones and reduce stress.
Prioritise sleep:
Aim for 7–9 hours each night to allow hormonal regulation and cell repair.
Manage stress:
Try deep breathing, journaling, acupuncture, or joining a support group.
Limit exposure to toxins:
Reduce contact with plastics containing BPA, harsh chemicals, alcohol, excessive caffeine (over 200 mg/day), and tobacco.
