Prevention

Rehabilitation

Hypovitaminosis D is a serious public health problem, representing an independent factor in mortality among the general population. Vitamin D deficiency may affect up to one billion people worldwide. Recently, the potential association between vitamin D levels and stroke has gained increasing attention. Many studies suggest that maintaining normal serum vitamin D levels is associated with improvement of the cardiovascular system and a reduction in stroke risk. As a neurosteroid, vitamin D influences brain development and function and immunomodulation and affects brain neuroplasticity. It supports many processes that maintain homeostasis in the body. As stroke is the second most common cause of death worldwide, more studies are needed to confirm the positive effects of vitamin D supplementation, its dosage at different stages of the disease, method of determination, and effect on stroke onset and recovery. Many studies on stroke survivors indicate that serum vitamin D levels only offer insignificant benefits and are not beneficial to recovery. This review article aims to highlight recent publications that have examined the potential of vitamin D supplementation to improve rehabilitation outcomes in stroke survivors. Particular attention has been paid to stroke prevention.

Stroke more likely if low Vitamin D

• Stroke 74% less likely if high vitamin D (7,295 women 20-50 years old) – July 2017
• Stroke is 13.5 X more likely if low vitamin D and high blood pressure – March 2015
• Ischemic stroke 17 X more likely if low vitamin D – April 2017
• Stroke is strongly associated with Calcification of cerebral arteries (perhaps low Vitamin D, Vitamin K, Mg…) – March 2018
• Ischemic Stroke 3X more likely if Vitamin D Receptor gene change (Fok 1) – Jan 2014

Post-Stroke worse if low Vitamin D

• Poor Acute Ischemic Stroke 4X more likely if low Vitamin D - Nov 2023
• Stroke risks increased if low Vitamin D: Death 3.6 X, recurrence 5.5 X – Meta-analysis Nov 2019
• Stroke outcome at 3 months was 3X worse if bad stroke and low vitamin D – Jan 2020
• Death after Ischemic Stroke 2.5 X more likely if less than 10 ng of Vitamin D – May 2019
• Vascular dementia (after strokes) 32X more likely in Hypertensives with low vitamin D – Oct 2015
• Depression following a stroke is 2.7 X more likely if low vitamin D – Sept 2018
• Stroke incidence not associated with low Vitamin D (but stroke outcome is) – Aug 2019

Post-Stroke better if add Vitamin D

• Post-stroke Vitamin D supplementation helped in 11 ways – May 2023
• Improved recovery from ischemic stroke with Vitamin D (300,000 IU injection) – RCT June 2018
• Better outcome following Ischemic stroke if injected with 600,000 IU of vitamin D – RCT Feb 2017
• Ischaemic stroke – Vitamin D doubled survival (Injection followed by monthly 60,000 IU) – RCT Aug 2016
• Stroke patients need more than 2,000 IU of vitamin D (found this time in Japan) – RCT June 2019

Post-Stroke better if Vitamin D actually gets to cells

• Resveratrol fights Parkinson, Alzheimers, Diabetes, Cardiovascular, ALS, Stroke, etc.– Nov 2018
• Stroke rehabilitation (and prevention) requires Vitamin D actually getting to cells – March 2020

VitaminDWiki - Injection contains

65 items in Vitamin D Injection category

• Vitamin D injections last longer (3 month vs 2 month) than loading doses
• Getting Vitamin D into your body shows the many ways of getting Vitamin D

• Injections are currently made by medical professionals into muscle
• Home injection of Vitamin D appears to be possible in the future
• Injections are useful for people who might forget to take their periodic supplement (children, elderly, etc) and those who cannot swallow or have poor digestion
• While Vitamin D2 is historically the common form, Vitamin D3 is far better
• Should check (if there is time) for possible allergic reaction to Vitamin D or lack of Magnesium for both for loading dose and injection
• Note 600,000 IU Vitamin D loading dose via capsules is 1/20th the cost($2.40) of an injection, and does not require a prescription
• 100,000 IU single dose of vitamin D - 2010 has the following
  
• Vitamin D injection lasts longer and has bigger response than weekly oral – Jan 2017 has the following
  
• Non-oral Vitamin D should be a better form for MS, food allergy, PTSD, etc. – many studies might include injection

200K IU, wait 4 weeks, then 50K weekly for 8 weeks may be better than a 600K injection

The injection form takes ~10 days to get to the brain. The oral form takes about 1 day
And, the oral vitamin D is far far less expensive
