• Vitamin D3 (Cholecalciferol) 10,000 IU: fat-soluble vitamin — high-dose format for deficiency correction under medical supervision
• Functions: calcium/phosphorus absorption, bone mineralization, immune modulation, mood regulation
• Softgel in olive oil: optimal fat-based absorption

• Rapidly raises blood D levels in cases of confirmed severe deficiency
• Helps relieve muscle and bone pain associated with severe vitamin D deficiency
• Provides strong, intensive immune support when needed
• Suitable for those whose bodies struggle to absorb vitamin D at standard doses

• If your blood test shows vitamin D below 20 ng/mL and your doctor recommends a high dose
• If you experience severe bone and muscle pain linked to confirmed vitamin D deficiency
• If you have a health condition affecting vitamin absorption such as inflammatory bowel disease

• Medical supervision and regular blood tests are mandatory — high-dose vitamin D can accumulate and cause toxicity
• Completely unsuitable for children or pregnant women without specialist medical supervision
• Symptoms of vitamin D toxicity include nausea, abdominal pain, and excessive thirst — stop and see your doctor if you experience these

• Take exactly the dose your doctor specifies — typically one softgel daily or every other day
• Always take with a fatty meal for proper D3 absorption
• Have a blood test every 6 to 8 weeks when on a high dose to monitor levels and avoid toxicity

Q: Is 10,000 IU daily safe?

A: For a short period under doctor supervision with regular blood tests — yes, it is safe. The risk comes from long-term unsupervised use, as vitamin D accumulates in fat and can reach toxic levels.

Q: How long until my vitamin D level improves?

A: With a 10,000 IU dose, you typically see a significant improvement in blood tests within 6 to 8 weeks. Once levels reach normal range, your doctor will reduce the dose to a maintenance level.

Q: Should I take K2 alongside this high dose?

A: That is a great question — if you are taking high-dose D3 for an extended period, K2 helps direct calcium to bones and protects arteries. Discuss this with your doctor.
