Progesterone Levels Play a Key Role In Maintaining Strong Bones
Maintaining strong bones is crucial for overall health, especially as we age. While we often associate bone health with calcium and vitamin D, another important factor that is often overlooked is progesterone, a hormone that plays a key role in regulating bone density. The connection between progesterone and bone health can shed light on why it’s important to maintain balanced hormone levels for women, which becomes challenging as we enter perimenopause and then menopause. Let’s talk more about it.
What Is Progesterone?
Progesterone is a hormone produced mainly by the ovaries, with smaller amounts coming from the adrenal glands. It is involved in many bodily functions, including regulating the menstrual cycle, supporting pregnancy, neuronal health, influencing the development of the bone structure, and many more. Progesterone levels fluctuate naturally throughout a woman’s life, with significant changes during puberty, pregnancy, perimenopause, and menopause. During the 10-15 years before menopause (known as perimenopause), the levels of progesterone can vary dramatically cycle to cycle before finally plummeting in menopause.
How Does Progesterone Support Bones?
Research has shown that progesterone plays an important role in maintaining bone density and strength. Bone density refers to the amount of bone mineral content in a given area, and higher bone density typically means stronger bones. As we age, this becomes even more important as lower bone density increases the risk of fractures and conditions like osteoporosis.
One of the ways progesterone helps with bone health is by promoting the balance between bone resorption (the process by which bone is broken down) and bone formation. Bone remodeling is a continuous process, and progesterone helps keep this balance in check. It stimulates bone-forming cells (osteoblasts) while also inhibiting bone-resorbing cells (osteoclasts). When progesterone levels are low, this balance can shift, leading to increased bone loss and reduced bone density.
The Impact Of Decreasing Progesterone
As women reach perimenopause and menopause, progesterone production naturally decreases. This decline can contribute to bone loss, which may lead to conditions like osteopenia and osteoporosis, where bones become weak and brittle. In fact, some studies suggest that progesterone deficiency, particularly during menopause, accelerates the loss of bone mass, making bones more susceptible to fractures.
What’s more, progesterone imbalances can affect other hormones, such as estrogen, which also plays a crucial role in bone health. When both progesterone and estrogen levels drop, the risk of bone-related issues increases.
Get Back Into Balance
There are several ways to support healthy progesterone levels and, by extension, bone health. First, consuming a balanced diet rich in nutrients like calcium, vitamin D, and magnesium is key for bone health. Regular weight-bearing exercises, such as walking or strength training, can help stimulate bone growth and improve density.
While there are many things we can do to help our healthspan equal our lifespan, unfortunately, none of us can fully escape the impact of aging. For those in perimenopause or menopause, hormone replacement therapy (HRT) and/or botanical therapies to increase progesterone production may be considered. HRT not only supports your bone health but also improves other aspects of your health that are affected by hormone changes (such as brain and heart health).
