It seems to me that there are too many variables on dosage, based on the recipient’s physiology.

Blood level seems the only way to know you are getting what you need.

I keep mine above 65.

[rktman]

Hmmmmmmm! Just give out the secret number already.

Will it lower my PSA?

[MarlonRando]

what if you get a lot of sunlight

[Sacajaweau]

Take a walk in the sunshine...10 minutes...stop with the lotion unless you’re going to be in the sun for a stretch.

[aMorePerfectUnion]

Don’t know.

I take Standard Process Cyruta Plus to handle this.

[nickcarraway]

Can you keep it at that level by sun exposure?

[grumpygresh]

Which lab or testing company did you use for D level ? Or did you get lab at doctors office?

[goodnesswins]

Depends on where you live...those at equator have less cancer, I have heard

Another pharmacology article on Vitamin D that does not mention the *need* to supplement with Vitamin K in tandem. Vitamin D will shake up the excess calcium in your system. My understanding is that if you have sufficient Vitamin K in your system as well, the calcium will be deposited in your teeth and bones. If you do not have sufficient Vitamin K, the calcium may be deposited in your organs and arteries. A few people I know got on the high dose Vitamin D3 bandwagon, which is good, but did not take Vitamin K2 with it -- because doctor didn't say it was necessary and what does a dope like me know anyway. One ended up with angina. One ended up with calcified valves in her heart -- and rather than adding K2 to try and move it, the doctor gave her pig valves. She's no longer with us. My opinion is that D3 is amazing, but always take it with a little K2 unless you are a heavy blood-thinner user.

yes but most Africans die before age 35 from dysentery so I guess their teleromes are the least of their problems?

Curcumin, boron, and mangosteen powder can reduce your PSA, along with other supplements.

[Swirl]

Makes since, Ive read that D can accelerate the development of kidney stones.

[ConservativeMind]

Green tea extract (EGCG) also helps with PSA.

The vitamin D created by your body from sunlight has been shown to last longer than supplemental. As we age the bodies ability to manufacture vitamin D from sunshine wanes, if indeed you get enough sun.

The vaxx screwed up my body chemistry but the blood tests I had to undergo established the supplements I needed (D & Fe).

Most older people require a D supplement.

[Red Badger]

Then you die of skin cancer.............🙄

[MarlonRando]

thanks for the info

“The vitamin D created by your body from sunlight has been shown to last longer than supplemental.”

Vitamin D is released slowly from the skin into the blood over several days. Oral is digested immediately but is fat-soluable and can be stored and released over weeks.

I’m 79 and been taking Vitamin D for years. I never got Covid and can’t remember the last time I had a cold.
