Vitamin D3's impact on constipation inconclusive
We explored the effects of probiotic supplementation combined with vitamin D3 on constipation and motor symptoms in individuals with Parkinson's disease. This study focused on a group of patients who had chronic constipation and used a specific probiotic formula.

Over the course of three months, we evaluated 32 patients to see if the supplementation made a difference in their digestive health and overall symptoms. We carefully monitored factors like bowel habits and employed various assessments to track the subjects' progress.

While our findings indicated some benefits from the probiotic intervention, the specific impact of vitamin D3 alone on constipation remains unclear due to the combination with probiotics in our approach. Therefore, we cannot draw definitive conclusions about the effectiveness of vitamin D3 by itself in alleviating constipation. Our research does suggest that the gut microbiome plays a role in managing symptoms associated with Parkinson's disease, emphasizing the importance of ongoing investigations in this field.

My family tried this hormone D3, but it caused severe constipation. Recent studies suggest that dosage recommendations for D3 are too high. In Germany, D3 is prescribed only for severe deficiencies and in doses up to 1000 IU, yet higher doses are commonly suggested elsewhere without sufficient guidance.

Be cautious with D3; excessive consumption can lead to side effects like constipation and elevated calcium levels, which may cause nausea and other symptoms. It's wise to check your D3 and calcium levels before taking high doses, especially if combined with calcium.

Working treatment! This vitamin D works wonders. It's affordable, and the tablets are small and easy to swallow—just one a day. After three days, my stool issues improved. I realised the constipation was due to a vitamin D deficiency. A bonus is that my hair has stopped breaking. Highly recommend this product.

This drug works well as a preventative measure. I can confidently recommend it. I take one capsule in the morning with some fatty food for better absorption. My lethargy and drowsiness have vanished, and I feel energised. It has also effectively addressed my constipation issues.

Constipation relief
Excellent product! My hair isn't falling out, and I've noticed my constipation improved since taking it daily. I feel revitalised after a month of use, and my kids are also benefiting from it. The delivery was timely, and I’m glad I purchased it without issues.

Consult doctor advice
Pros: The high dosage of 2000 IU in a single capsule is great for vitamin D deficiency—promoting calcium absorption and boosting the immune system. Convenient and affordably priced. Cons: High dosage may not suit everyone; always consult a doctor first as overdosing can lead to nausea, weakness, and constipation.
