When considering the intake of Vitamin D, especially at a dosage of 800 IU per day, it is essential to evaluate your specific health conditions, including your heart issues and low blood pressure. Based on the information provided, it appears that you have mitral valve insufficiency and experience panic attacks, along with a low blood pressure reading of around 95/55 mmHg.
Firstly, the recommended daily allowance for Vitamin D varies by age, but for most adults, it is generally around 600 IU, with a safe upper limit of 4,000 IU per day. Taking 800 IU of Vitamin D is well within the safe range and is unlikely to cause any adverse effects. In fact, Vitamin D plays a crucial role in various bodily functions, including immune system support. Research has shown that adequate levels of Vitamin D can help reduce the risk of respiratory infections, which is particularly relevant in the context of viral infections.

Regarding your concerns about blood pressure and heart rate, Vitamin D is not typically associated with lowering blood pressure or increasing heart rate. Instead, it is known to have a stabilizing effect on cardiovascular health. However, individual responses can vary, and since you have existing heart conditions, it is always prudent to monitor how you feel after starting any new supplement.
It is also important to note that while Vitamin D can be beneficial, it should not replace any prescribed medications or treatments for your heart condition or panic disorder. Your anxiety about heart palpitations is understandable, especially given your medical history. If you experience any new or worsening symptoms after starting Vitamin D, such as increased heart palpitations or dizziness, you should consult your healthcare provider promptly.

In addition to supplementation, consider natural sources of Vitamin D, such as sunlight exposure, which can help your body synthesize this vital nutrient. If you are concerned about your low blood pressure, it may be beneficial to discuss this with your healthcare provider as well. They can help determine if your blood pressure readings are a cause for concern and whether any adjustments to your treatment plan are necessary.

In summary, taking 800 IU of Vitamin D daily is generally safe and may provide health benefits, including immune support. However, given your heart issues and low blood pressure, it is crucial to keep your healthcare provider informed about any changes in your health status and to discuss any concerns you may have regarding your treatment plan. Regular monitoring and open communication with your healthcare team will help ensure that you manage your health effectively while minimizing risks.
