Osteoporosis is often referred to as the "silent disease" because it can develop gradually, without showing obvious symptoms until a bone fractures. Understanding bone health is crucial as we age, particularly for individuals at risk of osteoporosis.
What is a T Score in Bone Density Tests? It’s a critical measure used to assess bone strength and predict fracture risk. This score compares your bone density to a healthy young adult of the same sex, helping doctors diagnose osteoporosis and guide treatment plans.
One of the best ways to assess the strength of your bones is through a bone density scan, commonly known as a DEXA scan. This test provides important information about your bone health and calculates your T-score—an indicator that helps doctors determine whether you have normal bone density, osteopenia, or osteoporosis.
In this blog, we’ll dive deep into what a T-score is, how bone density scans work, how you can improve bone health, and why understanding these aspects is vital for preventing future bone fractures and maintaining a high quality of life.
What is A T-Score in Bone Density Tests?
A T-score is a measure of bone density that is used in bone density scans to help diagnose conditions like osteopenia and osteoporosis. A T-score compares your bone density to that of a healthy 30-year-old of the same sex and ethnicity.
The result is expressed in terms of standard deviations (SD), which reflects how much your bone density differs from the average bone density of a young adult.
- Normal T-score: A T-score of -1.0 or above means your bone density is in the normal range. This suggests that your bones are strong and healthy.
- Osteopenia (Low Bone Density): A T-score between -1.0 and -2.5 indicates that your bone density is lower than normal, but it’s not low enough to be classified as osteoporosis. This is a warning sign that you are at increased risk of developing osteoporosis in the future.
- Osteoporosis: A T-score of -2.5 or lower means you have significantly reduced bone density, which makes your bones more fragile and prone to fractures.
Why is The T-Score Important?
The T-score is important because it gives your doctor a clear indication of how your bone health compares to a healthy individual of the same age and gender. It helps determine your risk of developing osteoporosis, a condition where bones become weak and fragile, making them more prone to fractures, especially in areas such as the hip, spine, and wrist. A low T-score could indicate the need for treatments and lifestyle changes to prevent fractures and maintain bone health.
What is A Bone Density Scan?
A bone density scan, also known as DEXA (Dual-Energy X-ray Absorptiometry) or DXA, is a non-invasive test that measures bone mineral density (BMD). The test uses X-ray technology to assess the amount of minerals, such as calcium, in your bones. The scan helps identify the risk of osteoporosis and determines whether you have normal bone density, osteopenia, or osteoporosis.
How Does A Bone Density Scan Work?
A bone density scan uses two low-dose X-ray beams at different energy levels to scan your bones. The amount of X-ray absorbed by your bones will be measured, and this data is used to calculate bone mineral density (BMD). The lower the BMD, the greater the likelihood of bone fractures. The scan typically takes about 10-20 minutes and is painless.
The most common areas scanned are the spine, hip, and wrist, as these are the areas most prone to fractures in individuals with osteoporosis.
When Should You Get A Bone Density Scan?
The National Osteoporosis Foundation (NOF) recommends that people begin bone density testing at the following ages:
- Women: Age 65 and older, or earlier if you have risk factors for osteoporosis such as family history, a small body frame, or use of medications like corticosteroids.
- Men: Age 70 and older, or earlier if you have risk factors such as low testosterone levels, a history of fractures, or use of certain medications.
People at higher risk of osteoporosis should be tested earlier, such as those with a family history of osteoporosis, long-term steroid use, or certain medical conditions like rheumatoid arthritis or Crohn’s disease.
Risk Factors for Osteoporosis
Several factors can increase the risk of developing osteoporosis and a low T-score. Some of the most common risk factors include:
- Age: As we age, our bone density naturally decreases. For women, the risk accelerates after menopause due to the drop in estrogen levels.
- Gender: Women are at higher risk than men, particularly after menopause when bone loss becomes more rapid.
- Family History: A family history of osteoporosis or fractures can increase your risk.
- Body Size: People with smaller body frames are at a higher risk of developing osteoporosis because they generally have less bone mass to begin with.
- Low Calcium and Vitamin D Intake: A diet low in calcium and vitamin D can impair bone health, as these nutrients are vital for bone strength.
- Physical Inactivity: Lack of weight-bearing exercise can result in weaker bones.
- Smoking and Excessive Alcohol: Both smoking and drinking excessive amounts of alcohol can lead to decreased bone density.
- Medications: Long-term use of steroids, anticonvulsants, and other medications can increase the risk of osteoporosis.
How To Improve Bone Health
If your T-score shows that you have osteopenia or osteoporosis, it’s important to take steps to improve your bone health and reduce the risk of fractures. Here are some key strategies:
1. Get Enough Calcium
Calcium is a critical nutrient for bone health, and it plays a vital role in maintaining bone strength. As we age, our body’s ability to absorb calcium decreases, so it's important to consume enough calcium-rich foods or supplements. Foods high in calcium include dairy products, leafy greens, and fortified foods.
The recommended daily intake of calcium varies by age and sex:
- Adults under 50: 1,000 mg/day
- Women over 50 and men over 70: 1,200 mg/day
2. Vitamin D for Bone Health
Vitamin D helps your body absorb calcium more effectively, and it is equally essential for bone health. Spending time in the sun and eating foods like fatty fish, egg yolks, and fortified foods can help you get sufficient vitamin D. For many individuals, vitamin D supplementation is necessary to meet daily requirements.
The recommended daily intake of vitamin D varies:
- Adults under 70: 600 IU/day
- Adults over 70: 800 IU/day
3. Exercise Regularly
Engaging in weight-bearing and strength-training exercises can help strengthen your bones. Exercises such as walking, jogging, and weightlifting can stimulate bone growth and help prevent bone loss. Try to aim for at least 30 minutes of exercise, most days of the week.
4. Consider Supplements
In addition to calcium and vitamin D, you may want to consider other supplements that support bone health. Magnesium, collagen, and vitamin K2 are also important for bone density and can help maintain bone strength.
- Marine Collagen: Collagen helps with bone regeneration, improving bone density and reducing the risk of fractures.
- Magnesium: Magnesium is important for bone formation and calcium regulation.
5. Healthy Lifestyle Choices
Smoking and excessive alcohol consumption can accelerate bone loss. Quitting smoking and reducing alcohol intake can help prevent osteoporosis. Also, maintaining a healthy weight is essential, as underweight individuals are at greater risk for osteoporosis.
Can Supplements Help With Osteoporosis?
Yes, certain supplements can be beneficial in supporting bone health, especially for individuals who cannot meet their nutritional needs through diet alone. Immunosciences’ Bone Health Supplements, such as CanReset and Calcium+, are formulated with a blend of calcium, vitamin D, magnesium, and collagen to support healthy bone density and reduce the risk of fractures.

Bone Health Diet And Osteoporosis: How Nutrition Plays A Role
Nutrition plays a crucial role in preventing and managing osteoporosis. A healthy diet rich in calcium, vitamin D, and other essential vitamins and minerals can help improve bone health. Some foods to include in your diet are:
- Dairy products (milk, yogurt, cheese)
- Leafy greens (spinach, kale)
- Fortified foods (orange juice, cereals)
- Fatty fish (salmon, sardines)
- Nuts and seeds (almonds, chia seeds)
By prioritizing your nutrition and making sure you get enough of the right nutrients, you can help protect your bones and improve your bone density.
