Opinion of the Scientific Committee on Food on the Tolerable Upper Intake Level of Vitamin D (expressed on 4 December 2002)

Association between serum 25-hydroxyvitamin D level and upper respiratory tract infection in the Third National Health and Nutrition Examination Survey. Ginde AA, Mansbach JM, Camargo CA Jr. Arch Intern Med. 2009 Feb 23;169(4):384-90. PMID: 19237723 Conclusions Serum 25(OH)D levels are inversely associated with recent URTI. This association may be stronger in those with respiratory tract diseases. Randomized controlled trials are warranted to explore the effects of vitamin D supplementation on RTI.

Want to take a nap you more qualified? Try to lie on the hammock swing. The study revealed that the swing gently in his sleep can affect brain waves, so you can create fast asleep. The results of studies published in the journal Current Biology June 21 issue of this explains why all the adults and babies fall asleep faster when they rocked.

Vitamin D Toxicity Fears Unwarranted Is vitamin D toxic? Not if we take the same amount nature intended when we go out in the sun. Vieth R. Vitamin D supplementation, 25-hydroxyvitamin D concentration, and safety. Am J Clin Nutr. 1999;69:842-56. Vieth attempted to dispel unwarranted fears in medical community of physiological doses of vitamin D in 1999 with his exhaustive and well-written review. D-Lite, Renew, & SunSplash UV/Tanning Systems Sunsplash Tanning System Is toxicity a concern for you? If so, then increase your levels the way nature intended, with ultraviolet B light! His conclusions: fear of vitamin D toxicity is unwarranted, and such unwarranted fear, bordering on hysteria, is rampant in the medical profession. Vieth R, Chan PC, MacFarlane GD. Efficacy and safety of vitamin D3 intake exceeding the lowest observed adverse effect level. Am J Clin Nutr. 2001 Feb;73(2):288-94. Even Ian Monroe, the chair of the relevant IOM committee, wrote to the Journal to compliment Vieth's work and to promise his findings will be considered at the time of a future Institute of Medicine review.

Upper levels of vitamin D intake were set at 50 microg/d (2000 IU/d) for all ages. Some individuals would require higher levels than these to achieve serum 25-hydroxyvitamin D concentrations for optimal calcium absorption. So much new information on vitamin D and health has been collected since the requirements were set in 1997 that this nutrient is likely the most in need of revised requirements. Vitamin D requirements: current and future. Weaver CM, Fleet JC. Am J Clin Nutr. 2004 Dec;80(6 Suppl):1735S-9S. Review. Erratum in: Am J Clin Nutr. 2005 Mar;81(3):729. PMID: 15585797

Vitamin D and cancer mini-symposium: the risk of additional vitamin D. Vieth R. Ann Epidemiol. 2009 Jul;19(7):441-5. Epub 2009 Apr 11. Review. PMID: 19364661 Conclusion The results of well-conducted trials of vitamin D lead to the conclusion that the current U.S. National Academy of Sciences-Institute of Medicine upper limit for vitamin D intake of 2000IU per day 1, 37 is excessively conservative. That intake would raise serum 25(OH)D by an average of about 50 nmol/L (20 ng/mL), well within the safe range of serum 25(OH)D concentrations that extends to 500 nmol/L (200 ng/mL). Intake of 4,000IU per day would raise serum 25(OH)D by an average of about 100 nmol/L (40 ng/mL). Even prolonged physiologic-replacement intake of 10,000IU per day of vitamin D3 would pose no known risk of adverse effects in virtually all adults.

"Today, goldenseal is marketed as a tonic to aid digestion, sooth upset stomach, and as an antibacterial and antiviral agent. It is considered a natural antibiotic and is most often combined with echinacea in preparations designed to strengthen the immune system. Many professional herbalists recommend goldenseal in herbal remedies for hay fever (also called allergic rhinitis), colds, and the flu. Goldenseal is considered a useful antiseptic (which is why some herbalists use it topically to disinfect cuts and scrapes) and astringent. It is commonly used to treat severak skin, eye, and mucous membrane inflammatory and infectious conditions (such as sinusitis, conjunctivitis, and urinary tract infections). It is also available in mouthwashes for sore throats and canker sores. Goldenseal has not been thoroughly investigated in scientific studies, but some trials have looked at berberine, one of the active compounds in goldenseal. Berberine is a substance widely used in Traditional Chinese Medicine to treat dysentery and infectious diarrhea. Berberine may be effective in humans for malaria, heart failure, and various types of infections, including upper respiratory problems."

"MedWire News: Zinc supplements could increase the risk for coronary heart disease (CHD) in healthy people by decreasing high-density lipoprotein (HDL) cholesterol levels, researchers claim. Initial findings from a meta-analysis in 14,238 participants from 20 trials suggested no impact of zinc supplements on plasma lipoprotein levels. But a secondary analysis in healthy individuals showed that zinc was associated with a significant decrease in plasma HDL concentrations. Furthermore, zinc was linked with a significant decrease in HDL cholesterol levels among participants with Type 2 diabetes or those undergoing hemodialysis. The researchers suggest the result in patients with diabetes may relate to the action of zinc in determining insulin levels. The meta-analysis included 33 interventions investigating the impact of zinc on lipid levels. The mean dose of elemental zinc used was 58 mg per day, which the researchers note is beyond the recommended upper level of intake of 40 mg."

"Lancet 2010; Advance online publication MedWire News: There is a U-shaped relationship between glycated hemoglobin (HbA1c) levels and mortality in people with diabetes, say researchers, meaning that intensive glucose-lowering therapy could be as harmful as uncontrolled hyperglycemia. Writing in The Lancet, Craig Currie (Cardiff University, UK) and team say that if their findings are confirmed then diabetes guidelines may need to be revised to include a lower as well as an upper HbA1c threshold. Currie's team used the UK General Practice Research Database from November 1986 to November 2008 to obtain data on two cohorts of patients aged 50 years and older with Type 2 diabetes. The patients comprised 27,965 individuals whose treatment had been intensified from oral monotherapy to combination therapy with oral blood-glucose lowering agents, and 20,005 who had changed to insulin-containing regimens."

Vitamin A - a fat soluble vitamin with an RDA of 3000 IUs for men and 2,333 IUs for women. The upper suggested limit for daily intake is 10,000 IUs. Vitamin A is used in the body for white blood cell production, white blood cell health, cell division and growth. Common food sources of the vitamin include carrots, liver, broccoli, sweet potatoes and kale.

Safety of vitamin D3 in adults with multiple sclerosis. Kimball SM, Ursell MR, O'Connor P, Vieth R. Am J Clin Nutr. 2007 Sep;86(3):645-51. PMID: 17823429 Conclusions: Patients' serum 25(OH)D concentrations reached twice the top of the physiologic range without eliciting hypercalcemia or hypercalciuria. The data support the feasibility of pharmacologic doses of vitamin D3 for clinical research, and they provide objective evidence that vitamin D intake beyond the current upper limit is safe by a large margin.
