1. Product Introduction

Cholecalciferol is a form of Vitamin D that is converted in the body into active metabolites. These help regulate calcium and phosphorus absorption and support normal bone and teeth mineralisation.

D3 KAND Drops provide an oral formulation of Vitamin D3. They may be used when supplementation is recommended, but the required amount varies by age, dietary intake, deficiency status and product strength.

2. Uses of Medicine

Vitamin D3 drops may be recommended by a healthcare professional for:

• Prevention or treatment of Vitamin D deficiency.
• Supporting normal calcium absorption and bone mineralisation.
• Supporting healthy bone development in children when supplementation is indicated.
• Supporting bone health in people whose Vitamin D intake or status is inadequate.
• Management of specific conditions associated with Vitamin D deficiency, as part of a medical treatment plan.

The appropriate use depends on the product label and individual requirements. These drops are not a substitute for evaluation of persistent bone pain, muscle weakness or other unexplained symptoms.

3. Potential Benefits

• Helps the body absorb calcium and phosphorus from the digestive tract.
• Supports normal bone and teeth mineralisation.
• Helps prevent or correct Vitamin D deficiency when used appropriately.
• Supports normal skeletal development in growing children when supplementation is needed.
• Contributes to normal muscle function and other physiological processes.

Benefits depend on whether supplementation is needed and whether the correct amount is taken. Taking extra Vitamin D does not necessarily provide additional benefit.

4. Possible Side Effects

Vitamin D3 is generally well tolerated when used in an appropriate amount. Excessive intake can cause Vitamin D toxicity and elevated blood calcium levels (hypercalcaemia).

Possible symptoms of excessive intake include:

• Nausea, vomiting or constipation.
• Loss of appetite or unexplained weakness.
• Excessive thirst or frequent urination.
• Dehydration or abdominal discomfort.
• Kidney stones or kidney injury in serious cases.
• Rarely, itching, rash or other hypersensitivity reactions.

Seek medical advice promptly if an overdose is suspected or symptoms such as persistent vomiting, unusual thirst, frequent urination or marked weakness develop.

5. How to Use

• Use according to the product label and the healthcare professional's instructions.
• Check the concentration before measuring each dose.
• Use the supplied dropper or an appropriate oral measuring device.
• Do not assume that the number of drops from one brand equals the same dose from another brand.
• For infants and children, follow the exact prescribed amount; do not estimate a dose from age alone.
• Include Vitamin D from other supplements when reviewing the total amount being taken with a clinician.

The product strength and concentration have not been supplied, so no individual dose or number of drops is specified here.

6. How It Works

After absorption, cholecalciferol is converted in the liver to 25-hydroxyvitamin D and then primarily in the kidneys to its active hormonal form, calcitriol.

Active Vitamin D increases calcium and phosphorus absorption from the intestine and helps regulate their use in the body. This supports normal bone mineralisation and calcium balance.

7. Safety Advice

• Kidney disease: Ask a clinician before use if you have kidney impairment or a history of kidney stones.
• High calcium levels: Vitamin D may be unsuitable for people with hypercalcaemia or certain disorders that increase calcium levels.
• Other supplements: Tell the clinician about other Vitamin D or calcium-containing products to avoid excessive combined intake.
• Other medicines: Report medicines such as thiazide diuretics or digoxin, which may require additional consideration in the setting of Vitamin D or calcium changes.
• Infants: Use only the concentration and amount recommended for the child. Concentrations can differ considerably between products.
• Pregnancy or breastfeeding: Seek professional advice about the appropriate amount for your circumstances.
• Monitoring: Higher-dose or prolonged treatment may require clinical review and blood tests, depending on the indication.

8. Quick Tips

• Check the label for the exact IU per drop or IU per mL.
• Use the correct measuring device and follow the recommended amount.
• Do not combine multiple Vitamin D supplements without checking the total intake.
• Keep the bottle securely closed and out of children's reach.
• Follow the manufacturer's storage instructions.
• Do not increase the dose because symptoms persist or improve slowly.
• Seek medical advice if an excessive amount may have been taken.
