I did lab test of vitamine D3 and B12 today.
I must note here that i take 3000-4000UI of vitamine D3 a day
for last 1,5 year, did skin tanning all summer for vitamine D.
This results is pure evidence that "we all" hawe systemic
problems with vitamine D absorbtion, eg VDR receptors as genetics results
showed, or infection/toxins take place to our VDR receptors, gut problems
fat malabsorbtion, liver problems, kidneys problems...
B12 544,3 174-878
D3 22,13ng/ml 30-100ng/ml
Absorption issues OR our immune system is using it up more than normal because of POIS inflammation. Thus we have greater D3 needs than normal.
I personally feel best on 20,000iu per day and this is after testing 2000iu, 7000iu, and 14,000iu dosages respectively.
Dr Berg on YouTube has some interesting perspectives on D3 supplementation, the main ones being:
- Not all D3 you supplement is absorbed, from memory he stated it’s only 60-80%.
- Current RDAs for D3 is based on old data and information.
- 20,000iu feels like a lot, but when you convert it to mcg of D3, it’s 500mcg or 0.5mg
He thinks a maintenance dose should be between 10,000iu-20,000iu.
He also states that vitamin D3 toxicity is very similar to K2 deficiency. And that D3 toxicity is very rare.
It’s very important to supplement K2 alongside D3 for these reasons.I think everyone here should listen to their body with D3, and don’t be surprised if it likes higher dosages between 10,000-20,000. Obviously get your bloods done, and none of this is medical info. Follow at your own risk, I’m not a doctor.
