Medication Concepts


Hello, Doctor.
I am currently taking Rosuvastatin, Dexamethasone, and Berberine enteric-coated granules.
Can I take Vitamin C and calcium supplements? If so, should they be taken separately? I apologize for the interruption and thank you for your response.

San, 40~49 year old female. Ask Date: 2020/05/05

Dr. Huang Shenggang reply Pharmacology


Hello San: Thank you for your question.
After checking, there are no interactions between Rosuvastatin, Daliquel tablets, and Berkey enteric-coated granules with vitamin C and calcium supplements.
Calcium is suitable to be taken before bedtime, as it has calming effects and helps stabilize nerve function.
Taking vitamin C with calcium supplements is more effective because vitamin C can aid in calcium absorption.

More Info


When considering the simultaneous intake of Vitamin C and calcium with your current medications, it's essential to understand both the interactions between these supplements and your prescribed medications, as well as the optimal timing for their consumption.

Based on the medications you mentioned—冠脂妥 (Crestor), 達利全錠 (Dali-Total), and 伯基腸溶微粒 (Berkey enteric-coated granules)—there are generally no significant interactions reported with Vitamin C or calcium. This means that taking these supplements alongside your medications should not adversely affect their efficacy or your health. However, it is always prudent to consult with your healthcare provider or pharmacist to confirm this, as individual responses can vary based on personal health conditions and other medications you may be taking.


Benefits of Vitamin C and Calcium
1. Vitamin C: This vitamin is known for its antioxidant properties and plays a crucial role in collagen synthesis, immune function, and the absorption of iron from plant-based foods. It can also enhance the absorption of calcium, which is beneficial for bone health.

2. Calcium: This mineral is vital for maintaining strong bones and teeth, and it plays a role in muscle function, nerve signaling, and heart health. Adequate calcium intake is particularly important if you are at risk for osteoporosis or have dietary restrictions that limit calcium sources.


Timing of Intake
While you can take Vitamin C and calcium together, separating their intake can sometimes enhance absorption and reduce the risk of gastrointestinal discomfort. Here are some recommendations:
- Calcium: It is often suggested to take calcium supplements in the evening, as they may help with sleep and stabilize nerve function. However, if you are taking calcium carbonate, it should be taken with food to enhance absorption.

- Vitamin C: This can be taken at any time of day, but it is often recommended to take it in the morning or with meals to maximize absorption and minimize potential gastrointestinal side effects.


Additional Considerations
1. Dosage: Ensure that you are not exceeding the recommended daily allowance for Vitamin C and calcium. For most adults, the recommended daily intake for Vitamin C is about 75-90 mg, while calcium needs can vary from 1,000 to 1,200 mg depending on age and gender.

2. Dietary Sources: While supplements can help meet your nutritional needs, it is always best to obtain vitamins and minerals from a balanced diet rich in fruits, vegetables, dairy products, and whole grains. Foods high in Vitamin C include citrus fruits, strawberries, bell peppers, and broccoli, while dairy products, leafy greens, and fortified foods are excellent sources of calcium.

3. Potential Side Effects: High doses of Vitamin C can lead to gastrointestinal issues such as diarrhea and stomach cramps. Additionally, excessive calcium intake can lead to kidney stones and may interfere with the absorption of other minerals.

4. Monitoring: If you experience any unusual symptoms or side effects after starting these supplements, it is important to consult your healthcare provider. Regular monitoring of your health status and medication effectiveness is crucial, especially if you have underlying health conditions.

In conclusion, you can take Vitamin C and calcium with your current medications, but consider separating their intake for optimal absorption and to minimize any potential side effects. Always consult with your healthcare provider for personalized advice tailored to your specific health needs.
