- This was a pilot study in 2010. A clinical trial is underway - results due in 2017
- Apparenly supplements/pills taken just after the last meal of the day have the longest time to be absorbed
- Consider taking a different form of vitamin D: 50% ?
- Have far more mono-unsaturated fats in your diet than poly-unsaturated fats
Every 1 unit increase in the Mono/Poly ratio ==> 6.5 ng/ml increase in vitamin D in blood
Suggest taking vitamin D with a few almonds.
- Get more Magnesium say 500 mg daily (of the element, not the compound) 20% ?
- Of some interest - one woman successfully takes her vitamin D and Magnesium just one day a month.

- Have enough Boron: 20% ?
- Have at least some fat in your diet in that meal, or perhaps just in a meal the day you get additional vitamin D: 10%?

- Cholesterol is essential for your skin to make vitamin D from the sun as well as adsorb vitamin D in your gut
- Have enough, but not too much Calcium 1 2 500 mg
- Have some, but not too much, vitamin A: 20% ?
- Reduce weight if obese - not an easy thing, but vitamin D will help about 30% of the obese lose weight: 70% ?
- Do not smoke - Smoking decreases Calcium which uses up vitamin D: 20% ?
- Do not use cola soft drinks - Cola, like smoking, reduces Calcium and thus vitamin D: 20% ?
- Omega-3 fatty acids may increase active vitamin D levels in your body by 60%
The study showed the increase for those with kidney failures who took 3 grams of Omega-3 daily
Hope to find a study of Omega-3 for those with functioning kidneys
- Poor absorption of Vitamin D is strongly related to type of gut bacteria – Dec 2020
Here is the summary of Co-factors web page - Aug 2012
|Co-factor||How Much||Benefit Bone||Bioavailability||Balance body||Notes|
|Calcium||<750mg||Yes||probably||Yes||Avoid getting too much|
|Magnesium||500mg||Yes||Yes||Yes||Very important, big range in bio-availability|
Studies have shown that, taken separately, the changes listed above will increase the benefits to oral vitamin D3 by a total of at least 2X
I, Henry Lahore, the admin of VitaminDWIki, did all of the above and seem to have gotten a HUGE (perhaps 60 ng) increase in my Vitamin D blood level
But, some of the increase might have been due to my trying to optimize the vitamin D from the sun
