Vitamin D is needed before many surgeries – many studies and RCTs

Summary of 20+ studies

1. Loading doses of 300,000 IU Vitamin D have been frequently used for adults
   More than 300,000 IU is sometimes needed for adults
   infants-Children might only need 10,000 IU per kg
2. Loading dose for the ICU should be given in a single day
   An oral dose does not result in a full response for 3+ days
   An injection does not result in a full response for several weeks
3. A gut-friendly form of Vitamin D should be used if patient has poor digestion
   Nanoemulsion sublingual or topical are fast acting (hours)
     Any form of vitamin D given just before/after surgery is better than none
4. All of the above also applies to ICU (Intensive Care Unit)
   4.8 X more likely to die within 28 days of ICU if low Vitamin D - Jan 2024
5. Vitamin D3, not Vitamin D2 should be used
6. Note: Some Chemotherapies are amplified so much by Vitamin D as to result in death if dose size is not decreased

DON'T GET SURGERY Unless You Do This First - Dr. Berg video March 2025

Free summary by GLASP AI

• The video emphasizes the importance of having sufficient vitamin D levels before any surgery to reduce complications and improve outcomes.
• Surgical procedures themselves can lower vitamin D levels (from an average of 42.7 to 28 in one study mentioned).
• Sufficient vitamin D before surgery helps reduce infection risk, supports immune function, decreases inflammation, lowers cardiovascular complications, and enhances wound healing.
• Low vitamin D is associated with 200% higher post-operative inflammatory markers and up to 8x higher risk of cognitive dysfunction after surgery.
• Some studies have used very high doses of vitamin D before surgery (100,000-600,000 IU) to saturate the body's cells, though these are short-term protocols, not long-term recommendations.
• Vitamin D supports adrenal function during the stress of surgery, helping to regulate the cortisol spike that can increase 4x following surgical procedures.
• The video recommends taking additional vitamin D approximately 3 days before surgery to allow time for cellular absorption.
• Vitamin D influences over 2,000 genes, with about 200 related specifically to adrenal function.
