If you have questionable vitamin D status, this post may be of interest.
It turns out, caffeine inhibits the Vitamin D receptor [1]. Yep.
So, if you are trying to up your vitamin D status, i suggest considering liposomal Vitamin D (QuickSilver Scientific K2/D3) first thing in the AM, and then before bed. Caffeine stays in your system around 6-12 hours depending on your ability to metabolize it:).
For another post, but important co factors for Vitamin D assimilation and synthesis include:
Zinc (liquid Zinc Sulfate - Mary Ruths is a favorite),
Magnesium (Ultra Mag By Pure Encaps, Mag SRT Mag Malate By Jigsaw Health, MagMind By Jarrow - Mag Threonate all favorites, and all second to epsom salt baths).
K2 (make sure you get enough, 400mcg / day)
B6
Other factors that effect Vitamin D - include compromised ability to absorb fat suluable nutrents, bile and or pancreatic enzyme shortages. You may be interested to know that phenols inhibit pancreatic digestive enzymes (coffee gets a double whammy here for inhibiting the digestion of fat soluable vitamins like D in the gut) [2]. Coffee is super high in phenols, and so are teas:).
Now my suggested Vit D form, begins to take more shape:).
