Too much Vit D

(Perth, Australia)

Hi again Wray, I've been telling loads of friends about your website and the Natpro cream when 'the conversation comes up'. Quite a few people I've spoken to say to me (although they're unsure themselves) oh you're taking too much vit D and you should be really careful about that. I'm no doctor but I was taking 2 x tabs at 1000 IU until I did some more reading on your site suggesting we don't get enough here in Oz so I've up'd it to 3-4 tabs each day. I don't think I am overdosing in any way but I would dearly love to have an answer in laymans terms for those kind of responses from friends. Thanks again for your kindness and faithful help for all us women.

I forgot to mention that I haven't been losing any weight and that frustrates me. I didn't exercise for 2-3weeks and lost 1kg but feel lousy for not keeping fitness level up anyway. So am upping my amount of natpro to 2 teaspoons per day - half tsp morning, half tsp lunch and 1 full tsp night and really sweating profusly just like I did when I was about 18 years old (now 47) especially arm pits. What should I do Wray. I don't eat alot of rubbish and try to keep an eye on that. Thanks for your help.

Too much Vit D
by: Wray

Hi Susan Always so good to hear from you. Well according to some experts 4000iu's per day is the optimum, according to Dr Cannell 5000iu's per day is optimal. He has such an excellent website, have a look through it, see here. Incidentally he's a psychiatrist, and is now running a study on vitamin D and autism. He believes it's a lack of vitamin D in the mother while carrying the child that leads to it. But??the latest research published this year says we should be taking 10,000iu's per day! See see here. The paper concludes "Universal intake of up to 40,000 IU vitamin D per day is unlikely to result in vitamin D toxicity." Blood levels have to reach 200ng/ml or 250nmol/L before toxicity is reached. This paper here, by Reinhold Vieth a vitamin D specialist, is on toxicity. But there is a fail safe mechanism in the body, the higher the blood level, the slower levels rise. Assuming one is not taking daft doses, as extraordinarily high doses have been taken, which were quickly reversed by stopping the D. One man inadvertently took 2,000,000iu's per day, that's 2 million iu's, not a typo! See here. Another study found that a single dose of 500,000iu's (half a million iu's) did no harm to the elderly. A month after the single 500,000iu dose, Vitamin D levels were about 40-50 ng/ml or 100-125nmol/L, two months later they were deficient again, only 30 ng/ml or 75nmol/L. These are a few papers on ageing and vitamin D, see here, here, here, here and here. I've run out of space so will start a new comment below. Take care Wray

Too much Vit D
by: Wray

Hi Susan It's always best to have a blood test done every 3 months whilst getting the level to the optimum. My first test showed I only had 34ng/ml. As I love experimenting, I decided not to take any vitamin D, I wanted to see if vitamin D was well absorbed via a skin cream. My first cream was 2000iu's/ml, it took 7 months for my level to rise to 42ng/ml. So I made a 5000iu's/ml cream, that increased my level to 59ng/ml, which I also did over a 7 month period. Still too low, but as I wanted to get my level up high quickly, I took 100,000iu's per day for a month, 50,000iu's per day the next month, 25,000iu's per day the next, then down to 5000iu's per day thereafter. It went from the 59ng/ml to 79ng/ml, which was my last test done in March and I intend having another in November. I hope it's even higher! Incidentally if a cold/flu should dare to show it's face, it's normally gone within 2 days if 100,000iu's is taken each day for 6 days. Although I've given my views in layman's terms, they really should read the studies before taking my word for it. But I hope this helps! Take care Wray

Too much vitamin D
by: Wray

Hi Susan I've just received a paper published 24th Oct 2011 which says " ?To be safe, vitamin D administration should be increased to 2,000 IU/day for neonates, 5,000 IU/day for children and 10,000 IU/day for all adults.? I can't give you the full paper, unless you purchase it yourself, and the abstract doesn't say much, but this is the link here. Take care Wray
