Vitamin D is a fat-soluble vitamin that is mostly known for its role in regulating calcium and phosphorus levels in the body. It is also associated with improved cardiovascular health and reduced risk of stroke. Vitamin D deficiency is prevalent worldwide and is considered a risk factor for stroke. Studies have shown that vitamin D deficiency is associated with worse outcomes in stroke patients and can lead to an increased risk of stroke. However, the relationship between vitamin D and stroke is complex and not fully understood. Some studies suggest that vitamin D supplementation may improve stroke outcomes and reduce the risk of recurrent stroke, while others have found no significant effects. Overall, more research is needed to determine the role of vitamin D in stroke prevention and treatment.

What You'll Learn
- Vitamin D deficiency is a risk factor for stroke

- Vitamin D can reduce the risk of another stroke
Vitamin D deficiency is a risk factor for stroke
Vitamin D deficiency is very common in stroke patients, with prevalence rates of 70-100% in the general population. Vitamin D deficiency is associated with increased prevalence of diabetes, hypertension, hyperlipidemia, and stroke. Studies have shown that patients with low vitamin D levels had two times larger areas of infarct when compared with normal vitamin D levels. For each 10 ng/ml decrease in vitamin D level, stroke recovery after three months decreased by half.
Vitamin D deficiency is a potential risk factor for stroke, and vitamin D supplementation has been shown to improve stroke outcomes. A single dose replacement of vitamin D has significantly improved stroke outcomes. Screening for vitamin D status is essential in ischemic stroke patients, and supplementation should be done to maintain vitamin D at a normal level.

Vitamin D deficiency is associated with worse outcomes after a stroke
Vitamin D deficiency is very common in India, with a prevalence rate of 70-100% in the general population. It is the most under-diagnosed and untreated nutritional deficiency in the world. Vitamin D deficiency is associated with an increased risk of vascular disease and ischemic stroke in healthy individuals. It is also associated with ischemic stroke risk and contributing factors such as hypertension, hyperlipidemia, diabetes mellitus, and ischemic heart disease.
Vitamin D deficiency is associated with worse outcomes in ischemic strokes. A study found that patients with low vitamin D levels had two times larger areas of infarct when compared with normal vitamin D levels. For each 10 ng/ml decrease in vitamin D level, stroke recovery after three months decreased by half.
There is a significant improvement in the stroke outcome after three months in those patients who were supplemented with vitamin D. Thus, screening for vitamin D deficiency in stroke patients is essential, and vitamin D replenishment will improve the stroke outcome.

Vitamin D supplementation can improve stroke outcomes
Vitamin D is mostly known for helping the body absorb calcium and contributing to bone health. However, research in recent decades has also looked at whether vitamin D levels affect cardiovascular disease, although with inconsistent results.
Vitamin D deficiency is very common in India, with prevalence rates of 70-100% in the general population. Vitamin D deficiency is widely prevalent in tropical countries like India despite abundant sunlight.
Vitamin D deficiency is associated with increased risk of vascular disease and ischemic stroke in healthy individuals. Vitamin D deficiency is associated with ischemic stroke risk and contributing factors being hypertension, hyperlipidemia, diabetes mellitus and ischemic heart disease.
Vitamin D deficiency is associated with worse outcomes in ischemic strokes. The outcome of stroke after vitamin D replenishment has not been much studied.
Vitamin D is a potential risk factor for stroke, and vitamin D supplementation has better outcomes in ischemic stroke patients with vitamin D deficiency. Single-dose replacement of vitamin D has significantly improved the outcome of ischemic stroke.
Vitamin D deficiency is associated with poor outcomes after stroke, whereas daily supplementation is associated with better outcomes.

Vitamin D can reduce the risk of another stroke
Vitamin D deficiency is a significant risk factor for ischemic stroke, and can increase the risk of another stroke. Vitamin D deficiency is associated with worse outcomes in stroke patients, and can cause an increased risk of hypertension, hyperlipidaemia, diabetes mellitus, and atherosclerosis, all of which are risk factors for stroke.
Vitamin D supplementation can improve stroke outcomes and reduce the risk of another stroke. A 2017 randomised controlled trial found that there was a "significant improvement in the stroke outcome after three months" in patients who were supplemented with vitamin D. Another study found that vitamin D supplementation "improves stroke outcome and cardiovascular function".
However, some studies have found that vitamin D supplementation does not reduce the risk of stroke. One study found that vitamin D supplementation does not protect against stroke, and is only helpful for old heart failure patients. Another study found that vitamin D supplementation does not improve rehabilitation outcomes in stroke patients.
Vitamin D can be obtained through sun exposure, or through diet, including fatty fish, cheese, and egg yolks.

Frequently asked questions
Vitamin D deficiency is a risk factor for ischemic stroke, with sun exposure, sex, age, race, diabetes, and genetics also playing a role. Vitamin D deficiency is associated with worse outcomes in ischemic strokes.
Studies have shown that vitamin D supplementation can improve stroke outcomes, especially in patients with vitamin D deficiency. However, the results are mixed, and the limitations of vitamin D supplementation merit some caution.
A single dose of 600,000 IU of cholecalciferol has been shown to improve stroke outcomes in patients with vitamin D deficiency. However, another study found that daily administration of 2,500 IU of vitamin D3 for four months did not improve endothelial outcomes. More research is needed to determine the optimal dosage of vitamin D for stroke patients.
