What Is Letrozole?
Letrozole is an oral medication that works by temporarily inhibiting the production of estrogen in the body. This causes the pituitary gland to produce more follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which can help stimulate the maturation and ovulation of eggs in women who have irregular ovulation or unexplained infertility issues.
It’s often one of the first fertility drugs prescribed since it is less invasive and has fewer side effects than other treatment options. Understanding dietary recommendations and restrictions can help increase the effectiveness of letrozole and minimize unwanted side effects.
What diet is recommended while taking letrozole?
There are no strict dietary guidelines to follow while taking letrozole, but maintaining a healthy balanced diet is always recommended. Focus on getting plenty of fruits, vegetables, whole grains, lean protein, and healthy fats from foods like olive oil and avocados. Stay hydrated by drinking lots of water as well.
Limiting caffeine and alcohol intake can also help, as large amounts of these substances may decrease fertility. However, small amounts like a cup of coffee or the occasional glass of wine are likely fine for most people.
Checking with your healthcare provider about specific dietary advice for your treatment plan is advised.
Foods To Avoid While Taking Letrozole For Fertility
While no foods are completely off limits, some foods should be limited or avoided when possible while taking letrozole. Here are some foods to avoid while taking letrozole for fertility:
- Limit soy intake: Soy foods like tofu, edamame, and soy milk contain estrogen-like compounds that can interfere with letrozole. So avoiding soy as much as possible or limiting portions is advised.
- Avoid grapefruit and grapefruit juice: Grapefruit and its juice are known to interact with many medications. With letrozole, grapefruit can increase side effects and impact how your body absorbs it – so avoiding it is best.
- Cut back on greasy, fatty, and processed foods: These types of foods are more difficult to digest and may worsen common side effects like nausea, headaches, and upset stomach when taking fertility drugs.
- Use alcohol and caffeine in moderation: While you don’t need to fully avoid alcohol or coffee while on letrozole, overdoing either can negatively impact fertility and may alter medication concentrations in the body. Limit to 1-2 caffeinated drinks and alcoholic beverages per day max.
- Be careful with supplements and herbal remedies: Always check with your doctor before taking supplements alongside fertility meds – some like licorice root, and St John’s wort, and even simple medications like antacids can interact with how letrozole works. Air on the side of caution and check first.
Sticking to a balanced diet rich in whole foods is always key. In some cases, your doctor may recommend supplementing with a multivitamin to help fill any nutritional gaps while avoiding certain foods. Be sure to check with them before taking any new supplements.

Foods To Eat While Taking Letrozole
Here are some of the best foods to eat while taking letrozole:
- Load up on fruits and vegetables: Fruits and veggies provide important antioxidants for fertility. Focus on nutrient-rich produce like citrus fruits, leafy greens, berries, and tomatoes. Try for at least 5 servings daily.
- Choose healthy proteins: Incorporate plant proteins like lentils, beans, and tempeh as well as animal proteins like eggs, chicken, salmon, and yogurt. These provide helpful nutrients like iron, zinc, and vitamin D.
- Enjoy whole grains: Opt for 100% whole grains like brown rice, oats, quinoa, and whole-grain bread over refined grains. Pair with plant or animal proteins for well-rounded meals.
- Don’t skimp on healthy fats: Avocados, nuts, seeds, olive oil, and fatty fish like salmon supply anti-inflammatory omega-3s that support fertility.
- Stay hydrated: Drink plenty of water, herbal tea, vegetable juice, and limit caffeine/alcohol. Proper hydration aids medication absorption and can help ease side effects.
Focusing your diet on minimally processed, nutrient-packed foods can help create the optimal nutritional foundation. Pair that with appropriate medication timing and you’ll give yourself the best chances possible!
What Foods Interact With Letrozole?
Several foods and beverages are known to interact with the medication letrozole and should be limited or avoided when possible:
- Grapefruit/Grapefruit Juice: Grapefruit contains compounds that can increase blood plasma concentrations and side effects of letrozole. Avoid eating grapefruit or drinking its juice when taking this medication.
- Alcohol: Drinking alcohol while on fertility medications like letrozole can worsen side effects. Alcohol may also impact the absorption rates of the drug, so it’s best to avoid or only drink in moderation.
- Soy foods: Soy contains phytoestrogens that can mimic estrogen in the body. Since letrozole works by decreasing estrogen levels, eating large amounts of soy could counteract its effects.
- Licorice: Some components found in licorice root can potentially increase the toxicity of letrozole. Limit candy, supplements, or teas containing licorice.
- Caffeine: While moderate caffeine intake is likely fine for most, high intakes may worsen side effects or impact the efficacy of fertility meds. Limit coffee, tea, soda, and chocolate.
Additionally, other hormonal supplements, some herbal remedies like St John’s Wort, and even antacids have the potential to interact with letrozole as well. Always check with your doctor!
