The daily choice between tea and coffee may do more than boost energy levels—it could also influence bone health and osteoporosis risk in older women.
- Regular tea consumption was associated with slightly higher bone mineral density in older women
- Women consuming more than 5 cups of coffee daily showed lower bone density in some groups
- Nearly 29% of postmenopausal women in India have osteoporosis in key bone regions
For many older women, the daily choice between tea and coffee may influence more than energy levels—it could also affect bone health.
A study from Flinders University found that regular tea consumption was associated with slightly higher bone mineral density (BMD) in older women, while very high coffee intake appeared linked to lower bone density in some groups (1✔ ✔Trusted Source

).
The findings come as osteoporosis remains a growing concern globally, including in India, where studies show nearly 29% of postmenopausal women have osteoporosis in key bone regions such as the lumbar spine and femoral neck (2✔ ✔Trusted Source

Researchers say compounds in tea may help support bone health, although experts stress that no single beverage can prevent osteoporosis on its own.
Could Your Daily Cup of Tea Help Protect Bones?
The new study, published in the journal Nutrients, analyzed data from the long-running Study of Osteoporotic Fractures (SOF), which included 9,704 women aged 65 years and older in the United States.
Researchers tracked participants’ tea and coffee habits across multiple assessments over approximately 10 years while repeatedly measuring bone mineral density in the hip and femoral neck using dual-energy X-ray absorptiometry (DXA), a specialized low-dose X-ray technique used to assess bone strength.
The researchers found that women who regularly drank tea had slightly, but significantly, higher total hip BMD than non-tea drinkers. The difference was modest, but researchers noted that even small improvements in bone density can reduce fracture risk across large populations.
“Even small improvements in bone density can translate into fewer fractures across large groups,” said Enwu Liu.
Interestingly, the benefits of tea appeared particularly stronger among women with obesity, suggesting body composition may influence how tea-related compounds interact with bone metabolism.
Why Might Tea Support Bone Health in Older Women?
Scientists believe the potential bone benefits of tea may be linked to natural plant compounds called catechins. These are antioxidant-rich polyphenols found especially in green tea and some black teas.
According to a review published in Metabolites, catechins may help bones in several ways (3✔ ✔Trusted Source

- Stimulating osteoblasts, the cells responsible for building new bone
- Reducing osteoclast activity, which breaks down bone tissue
- Lowering oxidative stress and inflammation, which contribute to bone loss
The review highlighted that catechins may improve bone remodeling by modulating pathways involved in bone formation and calcium regulation. Researchers also noted that catechins may suppress signals linked to excessive bone breakdown.
Another review published in Current Osteoporosis Reports similarly noted that regular tea drinking has been associated with lower fracture risk and better bone outcomes in several populations (4✔ ✔Trusted Source

Bone remodeling is the body’s natural process of continuously breaking down old bone and replacing it with new bone. As women age—especially after menopause—this balance can shift toward faster bone loss.
Why Are Older Women at Greater Risk of Osteoporosis?
Osteoporosis develops when the body loses bone faster than it can be replaced, making bones more porous, weak, and more likely to fracture. Women are particularly vulnerable after menopause because estrogen—a hormone that helps maintain bone metabolism—declines significantly with age.
Globally, osteoporosis affects nearly:
- 1 in 2 women over the age of 50
- 1 in 5 men over 50
The burden in India is especially concerning. The Indian systematic review reported high levels of both osteoporosis and osteopenia among postmenopausal women. Osteopenia refers to lower-than-normal bone density that has not yet progressed to full osteoporosis.
The review also noted that:
- Low calcium intake remains common among Indian women
- Fracture risk rises sharply after menopause
- Awareness and diagnosis of osteoporosis are still inadequate in many regions
Researchers warn that as India’s elderly population grows, osteoporosis-related fractures could place a major burden on healthcare systems.
Is Coffee Harmful for Bones or Is the Story More Complicated?
Unlike tea, coffee showed mixed results in the Flinders University study. Overall, moderate coffee intake did not show a strong harmful association with bone mineral density. However, women who consumed more than 5 cups of coffee daily were more likely to have lower BMD.
Researchers believe caffeine may influence calcium balance and bone metabolism. Some studies suggest caffeine can slightly reduce calcium absorption or increase calcium loss through urine, potentially affecting bones over time.
The study also found that women with higher lifetime alcohol intake who consumed coffee had lower femoral neck BMD, suggesting that alcohol and caffeine together may amplify negative effects on bone health.
However, the relationship between caffeine and osteoporosis remains scientifically debated. A study published in Scientific Reports found that higher caffeine intake was associated with a lower osteoporosis risk in some analyses, highlighting that results remain inconsistent across populations and study designs (5✔ ✔Trusted Source

Researchers say factors such as age, smoking, nutrition, physical activity, calcium intake, and overall dietary patterns may influence how coffee affects bone health.
What Do Experts Say Women Should Actually Do?
Researchers emphasize that the study does not mean people should suddenly stop drinking coffee or dramatically increase tea intake. Instead, the findings support moderation and overall healthy lifestyle habits.
“Our results don’t mean you need to give up coffee or start drinking tea by the gallon,” explained Enwu Liu. “But they do suggest that moderate tea consumption could be one simple way to support bone health, and that very high coffee intake might not be ideal, especially for women who drink alcohol.”
Experts continue to stress that the foundations of bone health remain:
- Adequate calcium intake
- Sufficient vitamin D
- Regular weight-bearing exercise
- Balanced protein intake
- Avoiding smoking and excessive alcohol
The researchers also cautioned that most of the women in the study were White, so the findings may not fully apply to all ethnic groups.
What Do These Findings Mean for Everyday Bone Health?
The new findings add to growing evidence that diet and everyday lifestyle habits may influence bone health as people age. Regular tea consumption was associated with slightly higher bone mineral density in older women, while excessive coffee intake appeared to be linked to lower bone density in certain groups.
However, experts caution that neither tea nor coffee alone determines osteoporosis risk. Bone health is shaped by a complex combination of hormones, nutrition, physical activity, genetics, and aging. While a daily cup of tea may offer some protective benefits, long-term bone health still depends on maintaining a healthy lifestyle and ensuring adequate nutrition throughout aging.
Frequently Asked Questions
Q: Can drinking tea improve bone health?
A: Some studies suggest that regular tea consumption may slightly improve bone mineral density due to antioxidant compounds called catechins.
Q: Is coffee bad for osteoporosis?
A: Moderate coffee intake may not be harmful, but very high coffee consumption could negatively affect bone density in some individuals.
Q: What is bone mineral density (BMD)?
A: Bone mineral density measures the strength and mineral content of bones and helps assess osteoporosis risk.
Q: Why are postmenopausal women at higher risk of osteoporosis?
A: After menopause, estrogen levels decline, which accelerates bone loss and increases fracture risk.
Q: Can tea or coffee alone prevent osteoporosis?
A: No. Bone health depends on multiple factors including diet, calcium, vitamin D, exercise, hormones, and overall lifestyle.
