As a healthcare professional, I understand the importance of ensuring that medications work effectively and safely in the body. When it comes to thyroid medication, particularly levothyroxine, it's crucial to be aware of potential interactions with vitamins and minerals that could affect its absorption and efficacy.
Levothyroxine is a synthetic form of the hormone thyroxine, which is used to treat hypothyroidism. It's essential for the body's metabolism and growth, and its absorption can be influenced by various factors, including certain vitamins and minerals.
**Vitamins and Minerals to Avoid with Levothyroxine:**
1. Iron: Iron supplements can significantly decrease the absorption of levothyroxine. This is because both iron and levothyroxine are absorbed in the small intestine, and their simultaneous intake can lead to competition for absorption sites. It is generally recommended to take iron at least 4 hours after levothyroxine to minimize this interaction.
2. Calcium: Similar to iron, calcium can also interfere with the absorption of levothyroxine. This is particularly true for calcium carbonate, which is often found in antacids and calcium supplements. Taking calcium within 4 hours of levothyroxine can reduce its effectiveness.
3. Magnesium: Magnesium, like iron and calcium, can interact with levothyroxine and reduce its absorption. This is especially pertinent if you're taking magnesium-rich antacids, as mentioned in the provided information.
4. Antacids: Many antacids contain ingredients like magnesium and aluminum, which can bind with levothyroxine and decrease its absorption. It's best to avoid taking antacids within several hours of taking levothyroxine.
5. Fiber Supplements: High-fiber supplements can also affect the absorption of levothyroxine. The increased fiber content can speed up gastrointestinal transit time, reducing the time available for levothyroxine to be absorbed.
6. Vitamin D: While the evidence is not as strong as with other minerals, some studies suggest that vitamin D may also have an impact on the absorption of levothyroxine. It's important to discuss with your healthcare provider if you're taking vitamin D supplements.
7.
Bile Acid Sequestrants: These are used to lower cholesterol and can bind to levothyroxine, reducing its absorption. They should be taken at a different time of the day from levothyroxine.
8.
Certain Foods: Foods high in fiber, calcium, and iron can also affect levothyroxine absorption. It's often recommended to take levothyroxine on an empty stomach, ideally 30 minutes to 1 hour before breakfast.
Best Practices:
- Timing: Take levothyroxine on an empty stomach, ideally 30 minutes to 1 hour before breakfast, to maximize absorption.
- Separation: Keep a 4-hour gap between levothyroxine and other supplements or medications that may interact with it.
- Hydration: Drink a full glass of water with levothyroxine to aid absorption.
- Avoid Certain Foods: Avoid high-fiber foods, calcium-rich foods like dairy products, and iron-rich foods immediately before or after taking levothyroxine.
- Consult Your Healthcare Provider: Always discuss your vitamin and supplement regimen with your healthcare provider to ensure there are no interactions with your thyroid medication.
It's important to remember that each individual's situation is unique, and what works for one person may not work for another. Always consult with your healthcare provider before making any changes to your medication or supplement routine.

Many people find this is easiest before breakfast. Levothyroxine interacts with minerals such as iron, calcium, and magnesium, which lower the activity of thyroid medicine. Many antacids contain magnesium and aluminum, so avoid taking them when you're on the thyroid supplement levothyroxine.
