Vitamin D and Hypertension

Is there a link between low vitamin D levels and resistant hypertension? 
⠀⠀⠀⠀⠀⠀⠀⠀⠀
A study published in the journal of Clinical and Experimental Hypertension (April 2, 2019) believes that there is, and found a statistically significant association between Vitamin D deficiency (levels lower than 20 ng/ml) and resistant hypertension (a blood pressure >140/90 mmHg despite the concurrent use of 3 antihypertensive agents of different classes). 
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Based on my research, an optimal level of vitamin D is between 60-80 ng/ml, but most labs will consider a Vitamin D above 30ng/ml as within normal range. l encourage my patients to aim for optimal rather than the low end of the range. 
⠀⠀⠀⠀⠀⠀⠀⠀⠀
As always, my message is: please be mindful when supplementing. Vitamin D is a fat soluble vitamin and over supplementing can result in toxicity. Please discuss your supplementation regime and lab work with your primary care provider, functional medicine doctor or other health professional.
