Hello Mayblin,
I'm pasting my Dexa report because I'm not sure on some of your questions. I have had recent blood work done, below results.
Calcium 10.3
vitamin D-25-Hydroxy 74
I am only on 1 prescription and take a handful of supplements for gut, VitD, Omegas, Multi-Vit over 50.

Dexa Scan
COMPARISON: None available.

LUMBAR SPINE: L1-L4
- Bone mineral density (BMD) = 0.878 g/cm2.
- T-score = -2.6
- Change (%) since most recent prior (if available): None available.

FEMUR: NECK MEAN
- Bone mineral density (BMD) = 0.809 g/cm2.
- T-score = -1.6
- Change (%) since most recent prior (if available): None available.

IMPRESSION:
1. WHO Classification: OSTEOPOROSIS. Fracture Risk: HIGH.

FRAX generally not reported for patients with normal or osteoporotic BMD, in
patients younger than age 40 or older than age 90, in non-steroid-treated
patients younger than age 50, or in patients currently undergoing
pharmacotherapy.

TREATMENT RECOMMENDATION:
The Bone Health & Osteoporosis Foundation recommends consideration to initiate
pharmacologic treatment in postmenopausal women and men >= 50 years of age who
have the following:
- OSTEOPOROSIS: T-score < = -2.5 at the femoral neck, total hip, lumbar spine,
33% radius by DXA
- OSTEOPENIA / LOW BONE MASS: T-score between -1.0 and -2.5 at the femoral neck
or total hip by DXA with a 10-year hip fracture risk >= 3% or a 10-year major
osteoporosis-related fracture risk >= 20% (i.e., clinical vertebral, hip,
forearm, or proximal humerus) based on the US-adapted FRAX model.

NOTE: All decisions for treatment should be discussed between the patient and
one of their individual healthcare providers.

============================================================
WHO CLASSIFICATION:
The T-score compares the patient's BMD to the average BMD of a young adult. The
criteria below are from the World Health Organization:
- NORMAL: T-score -1.0 or above
- OSTEOPENIA / LOW BONE MASS: T-score -1.1 to < -2.5
- OSTEOPOROSIS: T-score -2.5 or lower

ISCD International Society for Clinical Densitometry's 2013 consensus
conference:
In Postmenopausal Women and in Men Age 50 and Older:
- T-scores are preferred.
- The WHO densitometric classification is applicable.
In Women prior to menopause and Men less than Age 50:
- Z-scores, not T-scores are preferred. This is particularly important in
children.
- A Z-score of -2.0 or lower is defined as 'below the expected range for age'
and a Z-score above -2.0 is 'within the expected range for age.'
- The WHO diagnostic criteria may be applied in women in the menopausal
transition.
- Osteoporosis cannot be diagnosed in men under age 50 on the basis of BMD
alone.

THANK YOU for any and all information. It's all new to me and I'm pretty good at researching but Osteoporosis is all over the place.
