    "Osteoporoosin tiedetään olevan pääasiassa D-vitamiinin ja auringon valon puutesairaus. Afrikasassa osteoporoosi on tuntematon ja mitä pohjoisemmaksi tullaan sitä enemmän on luuston haurastumista ja murtumia. Lonkkamurtumia ei Afrikassa juuri tunneta ja murtumien määrä kasvaa samanikäisellä väestöllä monisatakertaisesti tänne pohjoiseen tultaessa. Nyt on selvinnyt että jo äidin raskauden aikainen D-vitamiinin saanti on tärkeää lapsen tulevalle luuntiheydelle. Ne brittiäidit, jotka käyttivät D-vitamiinivalmisteita sekä ne äidit,jotka synnyttivät kesällä saivat vahvempiluisia jälkeläisiä ja ero näkyi vielä 9 vuoden iässä. "

JOHTAVAT RAVITSEMUSTUTKIJAT VAATIVAT: D-VITAMIIIN SAANTISUOSITUKSET TULISI MÄ... - 1 views

    "American Journal of Clinical Nutrition lehden (AJCN) tammikuun 2007 numerossa julkaistussa laajassa kokoomatutkimuksessa kritisoidaan voimakkaasti nykyisiä alhaisia D-vitamiinin saantisuosituksia (1). Lehden tutkimuksessa päivittäinen turvallinen annostus terveille ihmisille nostetaan aivan uudelle tasolle. Tällä hetkellä yleisesti hyväksyttynä turvallisena ylärajana pidetään 50 mikrogrammaa päivässä, tämän seurauksena Suomessakin nostettiin vuonna 2006 päivittäinen saantisuositus 7 mikrogrammasta 10 mikrogrammaan. Tiedeyhteisö on jo pitkään kritisoinut liian alhaisia D-vitamiinisuosituksia. Useimmat D-vitamiini-asiantuntijat ovat sitä mieltä, että 25(OH)D:n veripitoisuus tulisi olla vähintään 80 nmol/l, jotta D-vitamiinista saavutettaisiin optimaalinen hyöty. Viitearvoalue 25(OH)D:lle on Suomessa määritetty 10 - 105 nmol/l (tavoitetaso 40-80 nmol/l). Jotta 97.5 % väestöstä pääsisi 80 nmol/l tasolle tulisi D3-vitamiinin saanti olla vähintään 75 ug (3000 ky)/pv (2)."

    Twice single doses of 100,000 IU of vitamin D in winter is adequate and safe for prevention of vitamin D deficiency in healthy children from Ushuaia, Tierra Del Fuego, Argentina. Tau C, Ciriani V, Scaiola E, Acuña M. J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):651-4. Epub 2007 Jan 25. PMID: 17257830 doi:10.1016/j.jsbmb.2006.12.027 These results disclosed that to prevent vitamin D deficiency for children at zones of risk at the south of our country, double supplementation of 100,000 IU of vitamin D during autumn and winter, would be adequate and safe.

    Sweat gland epithelial and myoepithelial cells are vitamin D targets. Koike N, Stumpf WE. Exp Dermatol. 2007 Feb;16(2):94-7. PMID: 17222221 DOI: 10.1111/j.1600-0625.2006.00513.x Nuclear receptor binding of 1,25(OH)2-vitamin D3 (vitamin D) in skin keratinocytes of epidermis, hair sheaths and sebaceous glands was discovered through receptor microscopic autoradiography. Extended experiments with 3H-1,25(OH)2-vitamin D3 and its analog 3H-oxacalcitriol (OCT) now demonstrate nuclear receptor binding in sweat gland epithelium of secretory coils and ducts as well as in myoepithelial cells, as studied in paws of nude mice after i.v. injection. The results suggest genomic regulation of cell proliferation and differentiation, as well as of secretory and excretory functions, indicating potential therapies for impaired secretion as in hypohidrosis of aged and diseased skin.

Hyödyllinen D-vitamiini - 0 views

  •  
    D-vitamiini on rasvaliukoinen vitamiini, jota saadaan ravinnosta. Se on myös hormoni, jota elimistö tuottaa ihossa auringonvalon vaikutuksesta. Veressä kiertävä D-vitamiini on näiden kahden summa. D-vitamiini on tärkeä vitamiini, joka esimerkiksi turvaa luulle tärkeiden rakennusaineiden riittävän saannin, vaikuttaa suotuisasti immuunipuolustusjärjestelmään ja vähentää infektiosairauksien riskiä

New Hot Paper Comment by Bruce W. Hollis - 0 views

  •  
    Vitamin D deficiency is a very serious health problem. Most people tend to think of it only in terms of skeletal problems; however, it is much more than that. Vitamin D deficiency has now been linked with a multitude of neoplasms, autoimmune dysfunction, compromised innate immunity and neurodevelopment in utero. Vitamin D is made in huge amounts when we go into intense sun. A fair-skinned individual can produce approximately 20,000 IU in 10 minutes' time with a total body exposure. A person with significant pigmentation will require up to 10 times the exposure to make an equivalent amount. In the winter at the latitude of Chicago, even a fair person cannot photo-produce vitamin D from mid-October through March. Thus, it is VERY important to have a realistic vitamin D recommendation as the current 200 IU/day recommendation is a joke

Vitamin D in the Spotlight; This critical nutrient builds bones, helps fight infection ... - 0 views

  •  
    For many years, vitamin D was boring--even to doctors. Because it was considered good for bones and not much else, multitaskers like vitamin A, B vitamins and vitamin E hogged all the press. But recent studies have thrust this long-neglected nutrient into the spotlight. Scientists now think vitamin D may affect everything from diabetes to cancer. They're also finding that many people don't have enough of it.

The antibiotic vitamin: deficiency in vitamin D may predispose people to infection | Sc... - 0 views

    In the July 2005 FASEB Journal, Adrian F. Gombart of the University of California, Los Angeles (UCLA) and his colleagues reported that vitamin D boosts production in white blood cells of one of the antimicrobial compounds that defends the body against germs.\n\nImmediately, Cannell says, the proverbial lightbulb went on in his head: Maybe the high doses of vitamin D that he had been prescribing to virtually all the men on his ward had boosted their natural arsenal of the antimicrobial, called cathelicidin, and protected them from flu. Cannell had been administering the vitamin D because his patients, like many other people in the industrial world, had shown a deficiency:
