Levothyroxine and Bone Health: Understanding the Risks and Benefits

Levothyroxine Health

Levothyroxine is a medication that is commonly prescribed to treat an underactive thyroid (hypothyroidism). This medication is necessary to ensure that the body is producing the correct amount of hormones in order to maintain its proper functioning. However, it has been suggested that the use of levothyroxine may increase the risk of developing osteoporosis, a condition characterized by reduced bone density and mass. It is therefore important to understand the potential benefits and risks associated with levothyroxine use when it comes to bone health.

Benefits of Levothyroxine for Bone Health

Levothyroxine has been found to offer some positive benefits for bone health. Studies have shown that levothyroxine can improve bone mineral density in individuals with hypothyroidism. Additionally, levothyroxine can help to reduce the levels of parathyroid hormone (PTH) in the body, which can decrease the risk of developing osteoporosis.

Risks of Levothyroxine for Bone Health

Although levothyroxine can offer some benefits for bone health, there are also certain risks associated with its use. If an individual is using levothyroxine, it is important to monitor their calcium levels closely as the use of this medication can lead to reduced calcium absorption. Additionally, if an individual is taking levothyroxine for an extended period of time, it may lead to increased bone resorption, which can put them at greater risk for developing osteoporosis.

Tips for Maintaining Bone Health While Taking Levothyroxine

Taking steps to maintain bone health is important for anyone taking levothyroxine. Here are some tips for maintaining bone health while on levothyroxine:

  • Get Enough Calcium and Vitamin D: Taking supplemental calcium and vitamin D can help to ensure that your body is getting enough of these essential nutrients. You should aim to get the recommended daily amounts of calcium and vitamin D.
  • Monitor Bone Markers: Keeping track of your bone markers, such as PTH and vitamin D, can help you to identify any potential issues with your bone health.
  • Exercise Regularly: Regular exercise can help to maintain bone density and strength and can reduce the risk of developing osteoporosis.
  • Limit Alcohol Intake: Excessive alcohol consumption can increase the risk of developing osteoporosis, so it is important to drink in moderation and to avoid binge drinking.


Levothyroxine can offer some benefits for bone health, such as improved bone mineral density and reduced levels of PTH. However, there are also some risks associated with taking this medication for an extended period of time. It is important to take steps to maintain bone health while taking levothyroxine, such as getting enough calcium and vitamin D and exercising regularly. If you are taking levothyroxine, be sure to discuss any potential concerns with your doctor.
