@84hotshot84 1000iu/daily/D3 is required for each 25lbs you weigh. Take Country Life 5000iu that come in MCT oil. Vitacost or Swanson’s probably cheapest in USA
Iherb cheapest to UK (lower P&P) Code wab666 saves you$5 at IHERB.
Best consumed with largest meal of day.
@garydanny0 Yep it’s safe to take 10,000iu/daily but most people require 5000~8000iu Start with 1000iu/daily for each 25lbs you weigh, Get 25(OH)D tested after 3months to make sure this is sufficient to raise your level to 60ng/ml.
@TheMidnightBell07 Your doctor will have provided DRISDOL or similar Vitamin D2 ERGOCALCIFEROL.
BIOTECH Vitamin D3 50,000iu CHOLECALCIFEROL is the stuff you need. Less than $30 for 100 free shipping.
See The Case Against Ergocalciferol as a vitamin supplement. Full text is free online if you search. 50,000iu/D2 =15000iu D3.
D2 also speeds up the rate of Vitamin D catabolism so some people find the more they take the lower their vit d gets.
I take 4 pills of 50 000IU weekly. The good level is 100-150ng/ml and I am 125ng/ml
Skin color variation shows how important vitamin D is. Though natural selection, some of our ancestors died just because their skin was just a bit too dark as they migrated north out of Africa. The dark skin was not an efficient vitamin D absorber and it caused vitamin D deficiency. Only the lighter skin people survived as they migrated north where the sun was less direct. This is why you see skin color variation in humans, and it is proof of how important this
vitamin D is.
@hiii98 yes, a lack of vitamin d. Also smoking eliminates vitamin d. So if you live in the dark and smoke you’ve a higher chance of cancer.

@hiii98
i do!
important point
i am not convinced that exposure to sun causes cancer of the skin
they should study populations exposed to sun naturally
like fishermen somewhere
i think the exposure they target is touristic one
and i suspect there some hidden relation to cosmetics, ointments, other factors, even sunblockers themselves i think
Ive wondered,,some say sun is good,,others say its bad. Now think about this,,as a kid,,how much time did you spend in the sun? I remember spending almost all day in the sun as a kid playing,walking,riding a bike and so forth. So if the sun was so bad,,would not all the kids have problems from being in the sun? Makes sense to me,,the sun is not a bad thing, sunburn however feels very painful, I dont recall getting sunburn as a kid by being in the sun, hmm
@srdickens …I was in the sun, as much as a kid in SW Penna can be…I still got Malignant Melanoma…gratefully caught at In Situ phase!!
@kkkkkkatherine But I did not get any issues or problems from the sun. Perhaps its not so much the sun afterall is what I am saying that is the problem, perhaps its a genetic issue, as so many have spent so much time in the sun as kids,,as even kids still do and they have no problems. If it was all the sun and not a genetic issue,,then we all would have problems as kids from the sun, see my reasoning, it makes logical sense.
Awesome! Thank you.
@hiii98 -right, just don’t get more than 30 minutes at noon. That’s the optimal thing to do.
@kkkkkkatherine –we get melanoma when we stay in the sun all day long and many days that way. We get it when we get really bad sunburns when we are children and teens. And when we get more than one bad sunburn because we love the sun so much. I am a 22 year survivor of M M.
@durgaaa why not just play it safe and tan in a moderated consistant tanning bed and avoid the unpredictable sun? You are correct, sunburns are NOT tanning and it may lead to complications. ANYTHING done to excess will lead to problems. Tanning at a salon is regulated, responsible, moderated tanning and the best way to get vitamin D safely.
@hiii98 – you sound like the authority on the issue. Why should anyone challenge you or say anything more ?
Why the hell do people buy vitamins when the mark up of then are 800% for what is in the bottle. Heaven forbid some one did a medical study and proved it helped, the mark up goes to 1600%. There is not a dollars worth of vitamins or minerals in a 500 count bottle
You don’t know what quality or purity of the vitamins &mineral you get. You don’t know where it was manufactured at. Even if it says usa, it may only been put into bottles in the usa.
@samten10a What else are you going to buy. Plavix?
@samten10a Vitamin D wiped out my flu in about six hours. I took 45,000 IU spread out with food.
After six hours I only had a headache. I didn’t know at the time it was probably caused by low magnesium levels. Your body used MG with D. Vitamin K2 is also a cofactor. Eat green leafy vegetable and nuts and seeds for MG, K2, and other cofactors of vitamin D. If I stopped taking 15k IU every time I ate, then the flu symptoms would start to come back.
