Thyroid medication and milk should not be consumed together
In managing hypothyroidism, it's essential to take your Levothyroxin (L-Thyroxin) medication correctly to ensure its effectiveness. Two factors that can impact the absorption of this medication are dairy products and coffee.
Firstly, it's recommended to wait at least 30 to 60 minutes after taking levothyroxine before consuming coffee. This is because coffee can reduce the effectiveness of the medication if taken too close together. The same advice applies to other caffeinated beverages[2][4].
Secondly, it's crucial to separate the intake of levothyroxine and dairy products by at least 2 to 4 hours. Calcium, found in milk, yogurt, and other dairy products, can bind to levothyroxine and reduce its absorption[1][5].
The reason for these recommendations is that calcium forms an insoluble compound with levothyroxine in the stomach, affecting its absorption[5]. This can lead to the reappearance of symptoms such as fatigue, lack of drive, cold sensitivity, and weight gain[4].
The best practice is to take levothyroxine on an empty stomach, ideally 30 to 60 minutes before breakfast, and delay the intake of dairy or coffee accordingly to maximize the medication's effectiveness[1][3].
If you consume calcium or iron supplements in low doses, such as those found in multivitamins, the waiting time might be shorter. However, for calcium-rich foods like milk, a longer separation of 2-4 hours is safer[4][5].
It's important to note that this advice is specific to the interaction between coffee and Levothyroxin and does not apply to other foods or beverages.
Pharmacist Tabea Patz, as mentioned in the magazine "Diabetes Advisor" (Issue 8/2025), recommends this approach. She advises taking Levothyroxin with a glass of still tap water half an hour before breakfast to avoid potential interactions[1].
Remember, the information provided is not exhaustive, and individual responses to specific foods or beverages may vary. Therefore, it's crucial to discuss any concerns about eating habits and their potential impact on the effectiveness of thyroid tablets with a doctor.
The advice to avoid coffee after taking Levothyroxin is in addition to the previously mentioned advice about avoiding dairy products before and after taking the medication. By following these guidelines, you can help ensure optimal absorption of Levothyroxin and effectively manage your hypothyroidism.

- Maintaining a discipline in nutrition is vital for proper management of hypothyroidism. This might involve avoiding dairy products for at least 2 to 4 hours and coffee for at least 30 to 60 minutes after taking levothyroxine, as the absorption of the medication can be affected by these.
- Beyond fitness-and-exercise and mental-health, paying attention to the right therapies-and-treatments and nutritional habits is important for individuals with hypothyroidism. This includes being aware of the impact of calcium-rich foods on the absorption of levothyroxine.
- Medicare would benefit individuals with hypothyroidism by providing access to necessary health-and-wellness resources, such as information about appropriate medication usage and nutritional considerations for managing the condition.
- Adhering to these recommendations for the absorption of levothyroxine can help alleviate symptoms of hypothyroidism, such as fatigue, lack of drive, cold sensitivity, and weight gain. It's essential to consult with a healthcare professional for personalized advice and consider the individual's responses to specific foods or beverages.
