For osteoporosis, adults generally need 800-1000 IU (International Units) of Vitamin D daily, alongside sufficient calcium (around 1000-1200mg total from diet/supplements), to support bone health and reduce fracture risk, with doses ideally raising blood levels to >50 nmol/L (or >75 nmol/L for better response). Higher doses might be needed for deficiencies, but annual high-dose shots are discouraged; always consult a doctor for personalized needs and monitoring.
Clinical trials have shown vitamin D3 to be more efficient than vitamin D2 in reducing falls and fractures [3]Bischoff-Ferrari, H.A., et al., Fall prevention with supplemental and active forms of vitamin D: a meta-analysis of randomised controlled trials.
Taking more than the recommended amount of vitamin D is unlikely to improve your bone strength. It's possible to have too much vitamin D. Taking more than 100 micrograms (4000 IU) a day of vitamin D for a long time can be bad for your health.
The recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years.
Does vitamin D interact with other medications? Yes. Steroid medications such as prednisone can interfere with vitamin D metabolism. If you take steroid drugs regularly, discuss vitamin D with your doctor.
Vitamin D supplements can interact with other medications. Examples of vitamin D interactions include atorvastatin (Lipitor), cholestyramine (Prevalite) and phenytoin (Dilantin, Phenytek). Other Vitamin D drug interactions include orlistat (Xenical, Alli), digoxin (Lanoxin), and hydrochlorothiazide (Microzide).

The two most common mistakes when taking vitamin D are taking it without adequate fatty foods for absorption, and neglecting to take it with Vitamin K2 and magnesium, which are crucial for directing calcium to bones and activating the vitamin D in your body, respectively, leading to ineffective supplementation or calcium buildup issues. Many also mistakenly choose the less effective D2 form over D3, or take incorrect dosages without blood tests, according to this snippet from Healthshots, this snippet from GrassrootsHealth, this snippet from Yahoo! Health, this snippet from the Cleveland Clinic Journal of Medicine, and this snippet from Verywell Mind.
Two supplements that are often recommended are calcium and Vitamin D. Research has shown that getting the recommended daily doses of calcium and Vitamin D can help prevent bone loss. Calcium can come from dairy products, soy products or products fortified with calcium, such as cereals or orange juice.
There are two types of vitamin D supplements. They are vitamin D2 and vitamin D3. Previous research suggested that vitamin D3 was a better choice than vitamin D2. However, more recent studies show that vitamin D3 and vitamin D2 are fairly equal for bone health.
Taking too much vitamin D leads to calcium buildup (hypercalcemia), causing physical signs like nausea/vomiting, fatigue/weakness, frequent urination & excessive thirst, constipation, and confusion/disorientation, alongside potential bone pain or kidney stones, often from supplements, not sun exposure.
If you have osteoporosis, don't do the following types of exercises: High-impact exercises. Activities such as jumping, running or jogging can lead to fractures in weakened bones. Avoid jerky, rapid movements in general.
The fastest way to increase bone density involves a combination of high-impact weight-bearing exercises, resistance training, and ensuring adequate intake of calcium and Vitamin D, coupled with lifestyle changes like quitting smoking and moderating alcohol, as bones respond best to stress, nutrients, and a healthy environment to rebuild and strengthen. Focus on progressive overload in your workouts and consult a doctor before starting.
Bisphosphonates. For people at increased risk of broken bones, the most widely prescribed osteoporosis medicines are bisphosphonates. Examples include: Alendronate (Binosto, Fosamax).
Background: Adequate vitamin D is essential for maintaining optimal bone health, preventing and treating of osteoporosis. However, in recent years, large clinical trials and meta-analyses on the efficacy of vitamin D supplementation to prevent fractures in populations at different risks have been equivocal.
Low-fat dairy products, such as milk or yogurt, are rich in bone-building nutrients such as vitamin D, calcium, protein, potassium, zinc and phosphorus. Try to get three servings a day.
Parathyroid Hormone (PTH) Analog & PTH-Related Protein (PTHrP) Analog - These increase bone mass and are prescribed for those with severe osteoporosis or high fracture risk. Sclerostin Inhibitor - Blocks a protein to increase new bone formation and slow bone loss in severe osteoporosis cases.
Regular exercise is essential. Adults aged 19 to 64 should do at least 2 hours and 30 minutes of moderate-intensity aerobic activity, such as cycling or fast walking, every week. Weight-bearing exercise and resistance exercise are particularly important for improving bone density and helping to prevent osteoporosis.
An apparent vitamin D paradox, characterized by lower serum 25-hydroxyvitamin D (25(OH)D) levels and higher bone mineral density, is present in black population. In contrast, blacks have higher serum 1,25-dihydrox- yvitamin D (1,25(OH)2D) levels. The effect of 1,25(OH)2D on the skeleton is not fully understood.
Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body (hypercalcaemia). This can weaken the bones and damage the kidneys and the heart. If you choose to take vitamin D supplements, 10 micrograms a day will be enough for most people.
Vitamin D absorption can be prevented by limited sun exposure (dark skin, sunscreen, covering up, indoor lifestyle), medical conditions (celiac, Crohn's, cystic fibrosis, liver/kidney disease, obesity), certain medications (steroids, anti-seizure drugs, weight-loss drugs), and even some nutritional factors like low magnesium, with fat malabsorption issues and obesity being major culprits for preventing both dietary and sun-derived vitamin D from working effectively.
Many people enjoy the benefits of prednisone and other corticosteroids which are powerful anti-inflammatory drugs that can reduce pain and discomfort related to allergic reactions, arthritis, autoimmune conditions and more. In some cases, they even elevate mood, creating a sense of euphoria and excessive energy.
Paracetamol is complementary to prednisolone and will not interfere with its action. NSAIDs such as ibuprofen should not be taken when you are on steroids for GCA or PMR. But do discuss pain relief with your doctor. Don't be a martyr to pain.
Prednisone can make you feel different than normal. But there are steps you can take to decrease the risk of unwanted side effects. Things to avoid (or cut back on) while taking prednisone include: Caffeine: Combining caffeine with prednisone can keep you awake at night or make you feel jittery and anxious.
