Understanding the Root Causes Behind Bone Loss with Andrea Nakayama
When most women receive an osteoporosis diagnosis, the first question they ask is: “What should I take?”
But what if that’s the wrong question?
In this episode of Stronger Bones Lifestyle, I sat down with functional medicine nutritionist Andrea Nakayama to discuss a more empowering approach to bone health—one that looks beyond supplements and medications to understand why bone loss is happening in the first place.
Stop Focusing on the “What”
Andrea shared an important distinction between conventional and functional approaches.
Most healthcare conversations focus on the “what.”
What supplement should I take?
What medication should I use?
What food is best for my bones?
Functional medicine asks a different question:
Why is this happening?
Bone loss doesn’t occur in isolation. It’s often the result of multiple imbalances occurring throughout the body. When we understand those connections, we gain opportunities to support bone health naturally.
The Non-Negotiable Trifecta
Andrea begins every health investigation with three foundational areas:
Sleep
Poor sleep affects hormones, recovery, inflammation, and bone remodeling. Sleep isn’t simply a habit—it’s one of the body’s most important repair mechanisms.
Digestion
As Andrea explained, you can’t build with nutrients you can’t absorb.
Many women focus on calcium supplements while overlooking digestive issues that prevent proper absorption of minerals, protein, and other essential nutrients.
Blood Sugar Balance
Blood sugar impacts insulin, stress hormones, thyroid function, and sex hormones—all of which influence bone health.
A simple place to start? Include fat, fiber, and protein with every meal.
Think Roots, Not Branches
One of my favorite concepts from our conversation was Andrea’s “Three Roots, Many Branches” framework.
Symptoms and diagnoses are branches.
The roots are:
- Genetics and epigenetics
- Digestion
- Inflammation
Rather than chasing symptoms, we need to nourish the roots.
When the roots improve, the branches often improve as well.
This is why osteoporosis cannot be reduced to a calcium deficiency or an estrogen deficiency. Bone health reflects the overall health of the body.
Hormones Matter—But They Aren’t the Whole Story
Many women are hearing that estrogen is the answer to osteoporosis.
While hormones absolutely play a role, Andrea reminded us that sex hormones are only one piece of a much larger picture.
Before focusing solely on estrogen, we need to consider:
- Blood sugar regulation
- Insulin function
- Stress hormones
- Thyroid health
- Digestion and nutrient absorption
These systems are interconnected, and optimizing them creates a stronger foundation for healthy aging.
My Takeaway
The most empowering message from this conversation is that you are not powerless.
Your bones are responding to the environment you create every day through your sleep, stress levels, digestion, nutrition, movement, and mindset.
Instead of asking, “What supplement should I take?” start asking, “What is my body trying to tell me?”
That shift alone can completely change your bone health journey.

Frequently Asked Questions (FAQs)
Oxalates, also known as oxalic acid, are naturally occurring compounds found in many plants, vegetables, and fruits. They are part of a plant’s defense mechanism against predators and can be found in high concentrations in foods like spinach, rhubarb, beets, nuts, chocolate, tea, and certain beans.
Regarding bone health, oxalates can bind to minerals such as calcium in the gut, forming calcium oxalate. This compound is not easily absorbed by the body, meaning the calcium that could have been utilized for bone strengthening is instead excreted. This process can potentially lead to lower calcium availability for bone health, which can be particularly concerning for individuals at risk of osteoporosis or other bone-related issues.
However, for most women, dietary oxalates do not pose a significant threat to bone health, especially if their diet is balanced with enough calcium and they do not have a history of kidney stones.
Your gut is crucial for stronger bones for several reasons:
- Nutrient Absorption: The gut is where most nutrient absorption occurs. For bones to be healthy and strong, they need a variety of nutrients, particularly calcium, phosphorus, magnesium, and vitamin D. A healthy gut efficiently absorbs these essential nutrients from your diet and facilitates their transportation to the bones.
- Gut Microbiome and Bone Health: Research has shown that the gut microbiome (the community of bacteria living in your intestines) can influence bone density. Certain gut bacteria help in producing short-chain fatty acids (SCFAs) like butyrate, which have been shown to promote bone health. SCFAs can enhance the absorption of minerals necessary for bone strength and play a role in reducing inflammation, which can negatively affect bone health.
- Hormone Regulation: The gut helps regulate hormones that are involved in bone metabolism, including insulin, thyroid hormones, and sex hormones like estrogen. For example, estrogen is vital for bone density, and gut health can influence estrogen levels through the enterohepatic circulation, where estrogens are processed in the liver and intestines.
- Reducing Inflammation: Chronic inflammation, which can stem from poor gut health, is linked to many conditions that compromise bone strength, such as osteoporosis. A healthy gut helps to reduce systemic inflammation, protecting bones from inflammatory damage.
- Immune System Modulation: The majority of the immune system is located in the gut. An imbalance in the immune system can lead to autoimmune conditions, some of which affect the bones. Maintaining gut health helps to ensure the immune system works correctly, protecting against autoimmune reactions that could impact bone health.
In essence, maintaining a healthy gut contributes significantly to stronger bones by ensuring the effective absorption of vital nutrients, regulating hormones, reducing inflammation, and supporting a healthy immune system. Therefore, a diet rich in bone-healthy nutrients, prebiotics, and probiotics, along with lifestyle factors that promote gut health, is key to maintaining strong bones.
