Is the MP Treatment for Sarcoidosis Helpful for Other Chronic Diseases? MP's Vitamin D Theories Are Not Supported by Lab Studies. Updated July 2, 2008 "The MP treatment plan was originally designed to treat an inflammatory condition known as sarcoidosis. The treatment consists of using the drug Benicar, combined with the avoidance of all sources of vitamin D, and eventually adding various antibiotics, especially minocycline. After being used by sarcoidosis patients for some years, it was then theorized and claimed that the treatment could treat other inflammatory conditions. Eventually it was also claimed that it could treat fibromyalgia and CFS, conditions which are not recognized by the medical literature as being inflammatory in nature. "

Infant vitamin d supplementation and allergic conditions in adulthood: northern Finland birth cohort 1966. Hyppönen E, Sovio U, Wjst M, Patel S, Pekkanen J, Hartikainen AL, Järvelinb MR. Ann N Y Acad Sci. 2004 Dec;1037:84-95. PMID: 15699498

Daily duration of vitamin D synthesis in human skin with relation to latitude, total ozone, altitude, ground cover, aerosols and cloud thickness. Engelsen O, Brustad M, Aksnes L, Lund E. Photochem Photobiol. 2005 Nov-Dec;81(6):1287-90. PMID: 16354110 Vitamin D production in human skin occurs only when incident UV radiation exceeds a certain threshold. From simulations of UV irradiances worldwide and throughout the year, we have studied the dependency of the extent and duration of cutaneous vitamin D production in terms of latitude, time, total ozone, clouds, aerosols, surface reflectivity and altitude. For clear atmospheric conditions, no cutaneous vitamin D production occurs at 51 degrees latitude and higher during some periods of the year. At 70 degrees latitude, vitamin D synthesis can be absent for 5 months. Clouds, aerosols and thick ozone events reduce the duration of vitamin D synthesis considerably, and can suppress vitamin D synthesis completely even at the equator. A web page allowing the computation of the duration of cutaneous vitamin D production worldwide throughout the year, for various atmospheric and surface conditions, is available on the Internet at http://zardoz.nilu.no/~olaeng/fastrt/VitD.html and http://zardoz.nilu.no/~olaeng/fastrt/VitD-ez.html. The computational methodology is outlined here.

25-Hydroxylation of vitamin D3: relation to circulating vitamin D3 under various input conditions. Heaney RP, Armas LA, Shary JR, Bell NH, Binkley N, Hollis BW. Am J Clin Nutr. 2008 Jun;87(6):1738-42. PMID: 18541563 Conclusions: At physiologic inputs, there is rapid conversion of precursor to product at low vitamin D3 concentrations and a much slower rate of conversion at higher concentrations. These data suggest that, at typical vitamin D3 inputs and serum concentrations, there is very little native cholecalciferol in the body, and 25(OH)D constitutes the bulk of vitamin D reserves. However, at supraphysiologic inputs, large quantities of vitamin D3 are stored as the native compound, presumably in body fat, and are slowly released to be converted to 25(OH)D.

To conclude, our findings suggest an association between large-dose vitamin D supplementation in infancy and an increased risk of atopy, allergic rhinitis, and asthma later in life. Further study is required to determine whether these observations could imply that vitamin D supplementation in infancy may have long-term effects on immune regulation, or if they reflect some unmeasured determinants of vitamin D supplementation Infant vitamin d supplementation and allergic conditions in adulthood: northern Finland birth cohort 1966. Hyppönen E, Sovio U, Wjst M, Patel S, Pekkanen J, Hartikainen AL, Järvelinb MR. Ann N Y Acad Sci. 2004 Dec;1037:84-95. DOI: 10.1196/annals.1337.013 PMID: 15699498

Hypovitaminosis D in British adults at age 45 y: nationwide cohort study of dietary and lifestyle predictors. Hyppönen E, Power C. Am J Clin Nutr. 2007 Mar;85(3):860-8. PMID: 17344510 Conclusion: Prevalence of hypovitaminosis D in the general population was alarmingly high during the winter and spring, which warrants action at a population level rather than at a risk group level. Data from the 1958 birth cohort suggest that, at different cutoffs for hypovitaminosis D, a substantial public health problem exists in British whites. Obese participants and those living in Scotland were at the highest risk of hypovitaminosis D. However, the prevalence in the general population was very high during the winter and spring, which suggests that, to improve the situation, action is required at a population level rather than at a risk-group level. In the United States, calls have gone out for an increase in vitamin D fortification of foods (11), and the data from the current study suggest that such action is also warranted in the United Kingdom. Vitamin D is currently available without prescription as a dietary supplement only as part of cod liver oil or multivitamin products; hence, a need clearly exists to consider increased availability of over-the-counter supplements. Hypovitaminosis D has been implicated in the development of serious conditions, including diabetes, various types of cancer, and cardiovascular diseases, in addition to its essential role in maintaining bone health (1, 2). The high rates of hypovitaminosis D reported in this study suggest that immediate action is needed to improve the vitamin D status of the British population.

Strong correlations have been noted between cardiovascular diseases and low bone density / osteoporosis-connections so strong that the presence of one is considered a likely predictor of the other. This relationship has led to the hypothesis that these conditions share core pathophysiological mechanisms. Recent advances in our understanding of the complimentary roles played by vitamin D3 and vitamin K2 in vascular and bone health provide support for this hypothesis, along with insight into key metabolic dysfunctions underlying cardiovascular disease and osteoporosis. Part II, The Vitamin K Connection to Cardiovascular Health, reviews the ways in which vitamin K regulates calcium utlization, preventing vascular and soft tissue calcification while complimenting the bone-building actions of vitamin D, and also discusses vitamin K safety and dosage issues, and the necessity of providing vitamin K and vitamin A along with vitamin D to preclude adverse effects associated with hypervitaminosis D.

Strong correlations have been noted between cardiovascular diseases and low bone density / osteoporosis-connections so strong that the presence of one type of pathology is considered a likely predictor of the other. This potentially causal relationship has led to the hypothesis that these conditions share core mechanisms. Recent advances in our understanding of the complimentary roles played by vitamin D3 and vitamin K2 in vascular and bone health provide support for this hypothesis, along with insight into key metabolic dysfunctions underlying cardiovascular disease and osteoporosis. Part I of this review summarizes current research linking vitamin D deficiency to cardiovascular disease, the physiological mechanisms underlying vitamin D's cardiovascular effects, and leading vitamin D researchers' recommendations for significantly higher supplemental doses of the pro-hormone. Part II reviews the vitamin K connection to cardiovascular disease; the ways in which vitamin D and vitamin K pair up to prevent inflammation, vascular calcification and osteoporosis; and the necessity of providing vitamin K along with vitamin D to preclude adverse effects associated with hypervitaminosis D, which include vascular and other soft tissue calcification.

David Feldman, MD, professor of medicine at Stanford, explores the biological action of Vitamin D beyond its widely understood role in the information and maintenance of bone. Emerging therapeutic uses of the vitamin include the prevention and treatment of breast, prostate and colon cancer, chronic kidney disease and arthritis, among other conditions.

Vitamin D is safe when used in physiological doses (those used by Nature). Physiological doses are 3,000-5,000 IU/day, from all sources (sun, diet and supplements). Should hypercalcemia occur with such doses, it is due to vitamin D hypersensitivity syndrome, not vitamin D toxicity. Vitamin D hypersensitivity syndromes include conditions such as primary hyperparathyroidism, occult cancers (especially lymphoma) or granulomatous disease (especially sarcoidosis). In such cases, treatment of vitamin D deficiency should be done under the care of a knowledgeable physician. A serum 25(OH)D, serum 1,25(OH)D, PTH and SMA will lead the clinician in the right direction.

A few researchers are turning their attention to the sunshine vitamin as a culprit, prompted by the experience of immigrants that have moved from their equatorial country to two northern latitude locations As evidence of widespread vitamin D deficiency grows, some scientists are wondering whether the sunshine vitamin-once only considered important in bone health-may actually play a role in one of neurology's most vexing conditions: autism. The idea, although not yet tested or widely held, comes out of preliminary studies in Sweden and Minnesota. Last summer, Swedish researchers published a study in Developmental Medicine and Child Neurology that found the prevalence of autism and related disorders was three to four times higher among Somali immigrants than non-Somalis in Stockholm. The study reviewed the records of 2,437 children, born between 1988 and 1998 in Stockholm, in response to parents and teachers who had raised concerns about whether children with a Somali background were overrepresented in the total group of children with autism

Research finds people with gene variant who lack vitamin D, produced from sun exposure, can develop condition

ScienceDaily (Feb. 10, 2009) - Vitamin D is significantly associated with muscle power and force in adolescent girls, according to a new study. Although vitamin D is naturally produced in the body through exposure to direct sunlight, vitamin D deficiency has become widely common in the United States. Vitamin D deficiency has been shown to have a significant negative impact on muscle and bone health, and can lead to conditions including osteoporosis and rickets.

"Under year round UV exposure conditions (low latitudes, broken line, "High UV") there is no association between 25(OH)D and either prostate or pancreatic cancer. At high latitudes (Solid line, "Low UV") there is a positive association between blood levels of 25(OH)D and these cancers. The average year round levels of 25(OH)D actually tend to be higher in northern latitudes, higher than those where there is year-round solar UVB. Vieth explains that we know almost nothing about the enzymes controlling tissue 1,25(OH)2D levels and much of his discussion is extrapolated from renal enzyme activity."

Benefits of Vitamin D Supplementation Joel M. Kauffman, Ph.D. Journal of American Physicians and Surgeons Volume 14 Number 2 - Summer 2009 Clinical trials show that vitamin D supplementation at higher levels than previously recommended is beneficial for many conditions. It decreases the frequency of falls and fractures, helps prevent cardiovascular disease, and reduces symptoms of colds or influenza. Benefits are also seen in diabetes mellitus, multiple sclerosis, Crohn disease, pain, depression, and possibly autism. Sunlight does not cause an overdose of vitamin D production, and toxicity from supplementation is rare. Dose recommendations are increasing, but appear to be lagging the favorable trial results. A number of common drugs deplete vitamin D levels, and others may limit its biosynthesis from sunlight. People with adequate levels from sun exposure will not benefit from supplementation. While dietary intake is helpful, supplementation is better able to raise serum 25-hydroxyvitamin D , the major circulating metabolite, to the level now thought adequate, 30-50 ng/mL. Where there is inadequate daily sun exposure, oral doses of 1,000-2,000 IU/d are now considered routine, with much higher doses (up to 50,000 IU) for rapid repletion now considered safe.

Athletic performance and vitamin D. Cannell JJ, Hollis BW, Sorenson MB, Taft TN, Anderson JJ. Med Sci Sports Exerc. 2009 May;41(5):1102-10. Review. PMID: 19346976 doi: 10.1249/MSS.0b013e3181930c2b Conclusions: Vitamin D may improve athletic performance in vitamin D-deficient athletes. Peak athletic performance may occur when 25(OH)D levels approach those obtained by natural, full-body, summer sun exposure, which is at least 50 ng·mL-1. Such 25(OH)D levels may also protect the athlete from several acute and chronic medical conditions.

Vitamin D-induced up-regulation of tumour necrosis factor alpha (TNF-alpha) in prostate cancer cells. Golovko O, Nazarova N, Tuohimaa P. Life Sci. 2005 Jun 17;77(5):562-77. Epub 2005 Feb 25. PMID: 15904673 doi:10.1016/j.lfs.2004.10.072 Combined addition of human recombinant TNF-alpha with calcitriol or CB1093 cause enhanced effect in induction of apoptosis. We conclude that under physiological conditions vitamin D activates only the transcription of TNF-alpha gene, for TNF-alpha protein synthesis additional cofactors are required. Therefore a cooperation of vitamin D and TNF-alpha may play an important role in the control of cell growth in prostate cancer.

"Women from India, Pakistan and Sri Lanka with insulin resistance showed marked improvement after taking vitamin D supplements, says a study. Von Hurst, nutrition lecturer at the Institute of Food, Nutrition and Human Health at Albany, conducted the study for her doctoral thesis. Insulin resistance is largely symptom-free and sufferers are unaware of their condition. 'Once it has fully developed into type-2 diabetes, it can be treated, but not cured,' says Von Hurst. Von Hurst says that while diet and exercise play a major part in the onset of type-2 diabetes, her findings reinforce the importance of vitamin D from the sun and supplements to prevent type-2 diabetes. She also found evidence of vitamin D increasing bone strength in older women. "

Vitamin D and calcium insufficiency-related chronic diseases: molecular and cellular pathophysiology. Peterlik M, Cross HS. Eur J Clin Nutr. 2009 Dec;63(12):1377-86. Epub 2009 Sep 2. PMID: 19724293 doi:10.1038/ejcn.2009.105 A compromised vitamin D status, characterized by low 25-hydroxyvitamin D (25-(OH)D) serum levels, and a nutritional calcium deficit are widely encountered in European and North American countries, independent of age or gender. Both conditions are linked to the pathogenesis of many degenerative, malignant, inflammatory and metabolic diseases. Studies on tissue-specific expression and activity of vitamin D metabolizing enzymes, 25-(OH)D-1alpha-hydroxylase and 25-(OH)D-24-hydroxylase, and of the extracellular calcium-sensing receptor (CaR) have led to the understanding of how, in non-renal tissues and cellular systems, locally produced 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3) and extracellular Ca2+ act jointly as key regulators of cellular proliferation, differentiation and function. Impairment of cooperative signalling from the 1,25-(OH)2D3-activated vitamin D receptor (VDR) and from the CaR in vitamin D and calcium insufficiency causes cellular dysfunction in many organs and biological systems, and, therefore, increases the risk of diseases, particularly of osteoporosis, colorectal and breast cancer, inflammatory bowel disease, insulin-dependent diabetes mellitus type I, metabolic syndrome, diabetes mellitus type II, hypertension and cardiovascular disease. Understanding the underlying molecular and cellular processes provides a rationale for advocating adequate intake of vitamin D and calcium in all populations, thereby preventing many chronic diseases worldwide.

After much consideration into this blog's new name in the light of my new direction, the decision has been made. "Free the Animal" Why? First, if you read that post linked above, you know that my health and fitness approach is perfectly in harmony with my philosophical approach; and hence, my approach to politics and all that. In other words, a big part of the reason I have discovered something that truly works; and moreover, is the simplest, most natural, downright fun way of living: that gets you lean and fit; gets you feeling and sleeping great; and gets you looking years and years younger is precisely because I don't believe in the gods of heaven or earth, we evolved over millions of years and are conditioned by survival pressures that in no way include all vegetable diets, gorging on bottled water all day, eating ground grass seeds (grains and derivatives) running on a treadmill or elliptical, or involving ourselves in social schemes and cons that leave us powerless, with no influence, and at the mercy of the crowd and collective (the cannibal pot). Some have a lot of the pieces and do good work. I have all of the major pieces, though acquiring all of the specifics is a lifelong and never-ending journey of discovery. I will focus on essentials and specifics that really matter to me and others living a normal life in pursuit of survival, prosperity and happiness. I will point to other sources that provide more depth in specific areas that are of interest to only some
