Overview Osteoporosis and vitamin D contains the following summary
- FACT: Bones need Calcium (this has been known for a very long time)
- FACT: Vitamin D improves Calcium bioavailability (3X ?)
- FACT: Should not take > 750 mg of Calcium if taking lots of vitamin D (Calcium becomes too bio-available)
- FACT: Adding vitamin D via Sun, UV, or supplements increased vitamin D in the blood
- FACT: Vitamin D supplements are very low cost
- FACT: Many trials, studies. reviews, and meta-analysis agree: adding vitamin D reduces osteoporosis
- FACT: Toxic level of vitamin D is about 4X higher than the amount needed to reduce osteoporosis
- FACT: Co-factors help build bones.
- FACT: Vitamin D Receptor can restrict Vitamin D from getting to many tissues, such as bones
- It appears that to TREAT Osteoporosis:
- Calcium OR vitamin D is ok
- Calcium + vitamin D is good
- Calcium + vitamin D + other co-factors is great
- Low-cost Vitamin D Receptor activators sometimes may be helpful
- CONCLUSION: To PREVENT many diseases, including Osteoporosis, as well as TREAT Osteoporosis

Note: Osteoporosis causes bones to become fragile and prone to fracture
Osteoarthritis is a disease where damage occurs to the joints at the end of the bones
Osteoporosis is a systemic skeletal disorder characterized by a decrease in bone mass and microarchitectural deterioration of bone tissue. The World Health Organization has defined osteoporosis as a decrease in bone mass (50%) and bony quality (50%). Vitamin D, a steroid hormone, is crucial for skeletal health and in mineral metabolism. Its direct action on osteoblasts and osteoclasts and interaction with nonskeletal tissues help in maintaining a balance between bone turnover and bone growth. Vitamin D affects the activity of osteoblasts, osteoclasts, and osteocytes, suggesting that it affects bone formation, bone resorption, and bone quality. At physiological concentrations, active vitamin D maintains a normal rate of bone resorption and formation through the RANKL/OPG signal. However, active vitamin D at pharmacological concentration inhibits bone resorption at a higher rate than that of bone formation, which influences the bone quality and quantity.
Nutritional vitamin D rather than active vitamin D activates osteoblasts and maintains serum 25(OH)D3 concentration. Despite many unanswered questions, much data support nutritional vitamin D use in osteoporosis patients.
This article emphasizes the role of nutritional vitamin D replacement in different turnover status (high or low bone turnover disorders) of osteoporosis together with either anti-resorptive (Bisphosphonate, Denosumab et.) or anabolic (Teriparatide) agents when osteoporosis persists.Vitamin D helps treat Osteoporosis – Sept 2018
