I will thus cut down on supplementation to avoid vascular calcification.
- speakeron 8y ago> I will thus cut down on supplementation to avoid vascular calcification. Current good practice is to also supplement with vitamin K when taking D. This is to promote carboxylation of osteocalcin, so calcium is directed into bones rather than soft tissues[1].

- arkades 8y agoAn editorial arguing from animal models is not “current good practice”. Additionally, please no one take vitamin K supplements without speaking with your physician first. They’re a direct reversal agent for a class of anticoagulants, the prime example of which is warfarin. It’d suck if you accidentally had a stroke or pulmonary embolism because of a random internet comment.
- speakeron 8y agoI'd go further and say you that, if you're on medication, you shouldn't take any supplements without first checking with your doctor. With regards to vitamin K, all the versions of the supplement I've seen have a specific warning on the bottle that they're not to be used if you're also taking anticoagulants.
- rapsey 8y agoYou can get vitamin d light therapy lamps. Those are very effective
- semi-extrinsic 8y agoIf a light therapy lamp company claims their product will increase your vitamin D, they're either telling blatant lies, or they're giving you skin cancer. Only UV radiation (like in sunlight and tanning beds) triggers vitamin D production.
- rapsey 8y agoYes UVB to be precise. Vitamin d lamps are much narrower spectrum, often even a single wavelength of 311 nm. One popular model is fda approved and proven to be effective. UVA is the problematic wave length spectrum and vitamin d lamps stay clear of it (unlike tanning lamps that are focused on UVA). Exposure is also very short of 3min max.
- semi-extrinsic 8y agoTL;DR: only people with specific diseases should use UVB phototherapy lamps, and in those cases it would be prescribed by a doctor. UVB exposure does cause cancer, that much is undisputed [1]. However, with very short exposures following a correct schedule given by a doctor, UVB phototherapy can be an efficient treatment for Vitamin D deficiency in people with certain specific illnesses like cystic fibrosis or inflammatory bowel disease that cause digestive malabsorption of vitamins. This can also be an effective treatment e.g. for psoriasis. The increase in risk seems to be negligible when used like this [2], but for people without these specific diseases a normal Vitamin D supplement is unequivocally safer.

- inertiatic 8y agoI walk 50 minutes a day to work and back and live in relatively sunny Greece. Didn't stop me from developing a deficiency.
- Numberwang 8y agoJust take a normal dose..
- baccheion 8y agoCalcification can usually be avoided by also taking magnesium and vitamin K. 5,000 IU D3 : 1,000 mcg+ MK-4 or 5,000 IU D3 : 200 mcg+ MK-7.
