Co-factors increase Vitamin D response for the GRH cohort - Jan 2023

Important Nutrients to Make Sure You Are Getting Along with Vitamin D


The calculations below show how much more supplemental vitamin D was needed, on average, for participants to achieve a vitamin D level of at least 40 ng/ml (100 nmol/L), for those not taking each nutrient in supplement form compared to those taking each nutrient.

  • 244% more D needed if not taking both magnesium and K2
    • 146% more D needed if not take at least 400 mg/day magnesium
    • 115% more D needed if not take at least 200 mcg/day of vitamin K2
  • 94% more D needed if not take at least 1,000 mg/day vitamin C
  • 72% more D needed if not take probiotics
  • 63% more D needed if not take at least 20 mg/day vitamin B6
  • 61% more D needed if not take at least 500 mcg/day of vitamin B12
  • 14% more D needed if not take at least 500 mg/day calcium

GRH data
Example: addition of both Mg and K2 = yellow line

Note: The general public probably will not have aa good of a response as GRH

GRH cohort is probably both healthier and younger
The general public has more chronic diseases that reduce response to vitamin D supplementation
The general public has more chronic diseases that consume vitamin D, and so reduces response
The general public is probably more obese than the GRH cohort
The general public probably does not eat as well as the GRH cohort

Would be interesting to compare the US population pyramid with the US GRH cohort
   Suspect GRH participants are primarily aged 35-55
