If you are interested in Vitamin D there is some new data.

[Guest guest]

There is an update on the safety of high doses of vitamin D at

www.vitaminD3world.com Doses as high as 40,000IU per day, are now being used

without side effects. Look under `Choose your dose' and scroll down.

There is also new data in the `Cancer Treatment' section showing that prostate

cancer patients with low levels of vitamin D have almost 7 times the death rate

of those with high levels. So there is now similar data on improving

progression and survival rates in lung, colon, breast and now prostate cancer.

What toxicity are you concerned about? Data shows levels up to 130ng/ml and no

side effects. Hypercalcemia occurs if you take a lot of calcium with the vitamin

D. One constantly hears about fears of vitamin D toxicity but there is nothing

in the world literature to support it

Since vitamin D can cause toxicity, I'd be skeptical about using such doses. In

any case, check with the doctor before doing anything such as this.

Hello Karl

The link you quote said exactely what I said basically the increase is due to

the presence of too much calcium.

Concerns about vitamin D toxicity are overblown, along with those about sun

exposure. As one researcher in the field puts it, " Worrying about vitamin D

toxicity is like worrying about drowning when you’re dying of thirst. " The

LD50 of vitamin D in dogs (the dose that will kill half the animals) is

3,520,000 IU/kilogram. One can take a 10,000 IU vitamin D supplement every day,

month after month safely, with no evidence of adverse effect. (Am J Clin Nutr

1999;69:842–856). A person must consume 50,000 IU a day for several months

before hypercalcemia (an elevated calcium level in the blood, which is the

initial manifestation of vitamin D toxicity) might occur. Vitamin D in a

physiologic dose (5,000 IU/day) prevents the build up of calcium in blood

vessels. (Circulation 1997;96:1755–1760). If one takes 10,000 IU of vitamin D

a day and spends a lot of time in the sun, it would be prudent to check vitamin

D blood level to ensure that it does not exceed

100 ng/ml.

Both vitamin D and lymphomas are associated with hypercalcemia - a metabolic

imbalance resulting from too much calcium in the blood. Hypercalcemia can also

be a side effect of chemotherapy.

I think the take home message from the information below is that lymphoma

patients should be cautious about supplementing with vitamin D and getting too

much sun exposure. Certainly the existence of " vitamin D metabolite-mediated

hypercalcemias " 4 in lymphomas calls into question the idea of self-treating

lymphomas with vitamin D supplements.

Mike, I'm not qualified to say with certainty, but my intrepretation is that

folks with lymphoma need to be cautious about supplementing with vitamin D ...

because both the disease and treatment can lead to abnormall production of

calcium, which is mediated by vitamin D. That is, supplementing with D can

cause problems with C.
