"A small amount of sunlight on your skin (twenty to thirty minutes a day) is vital for the production of vitamin d3 (cholecalciferol), and essential for the absorption of calcium and other minerals. The sun's UVB rays react with cholesterol both inside and on the surface of the skin, creating vitamin d3, which helps you absorb and utilize calcium. Vitamin D3 ensures that our cellular nutrition goes through the proper cycle of metabolism, and the calcium ion, which opens the door to deliver the nutrients to the cell, depends on vitamin d3." - Timothy Brantley, The Cure: Heal Your Body, Save Your Life (Get the book.)

"In a double-blind trial, healthy people were given 400—800 IU per day of vitamin d3, or no vitamin d3, for five days during late winter. Results showed that vitamin d3 significantly enhanced positive mood and there was some evidence of a reduction in negative mood compared to a placebo.37 In another double-blind trial, people without depression took 600 IU of vitamin D along with 1,000 mg of calcium (page 483), or a placebo, twice daily for four weeks." - Alan R.

"Cholecalciferol is also called vitamin d3. It is the form used in many supplements and is sometimes used in food fortification. Forms of Vitamin D Vitamin D3, cholecalciferol, is made in the skin or taken as a supplement. Calcidiol is the storage and circulating form of vitamin D. Calcitriol is the active form of vitamin D. Vitamin D2, ergocalciferol, is made by irradiating fungi. Calcidiol is made from cholecalciferol in the liver. Calcidiol is the form of vitamin D that is stored in the liver. It is a precursor to the hormone calcitriol." - Dr. Steve Blake, Vitamins and Minerals Demystified (Get the book.)

"For the most exact dosing, you may want to have three blood tests; vitamin d3, intact PTH (parathyroid hormone), and calcium. The only way to know your vitamin D status definitively is to measure a blood level of 25-hydroxy-vitamin Dy Your blood maintains activated vitamin D (also known as 1,25-dihydroxyvitamin D3) at a relatively constant level even when you're deficient in vitamin D. Activated D levels are a better measure of kidney function than vitamin D status." - James Dowd and Diane Stafford, The Vitamin D Cure (Get the book.)

"A balanced diet rich in omega-3 essential fatty acids (from fish or flax oil) also will give you vitamin d3. If you don't live in the sun belt or high in the mountains where UBV rays are more potent, you might want to consider 185 taking cod-liver oil, which contains naturally occurring vitamin d3. After the summer months, you can derive naturally occurring vitamin d3 from organ meats, eggs, and fish. Do not supplement with synthetic vitamin D2 (ergocalciferol)." - Timothy Brantley, The Cure: Heal Your Body, Save Your Life (Get the book.)

"When buying supplements, make sure they are vitamin d3 and not vitamin D2, which is useless. If you do take vitamin d3 supplements, have your levels checked every three to six months, as too much can cause toxicity, though rarely. But please know that the best and safest way to get your daily dose of vitamin D is from the sun. Sun exposure doesn't cause vitamin D toxicity. However, if you live in a cooler climate, supplementation during the winter months is probably necessary." - Frank Lipman, Mollie Doyle, Spent: Revive: Stop Feeling Spent and Feel Great Again (Get the book.)

"Then, over the course of two to three days pre-vitamin D3 undergoes further changes in the skin to become vitamin d3 which is then carried via bloodstream to the liver and then the kidneys to become the biologically active hormone 1,25 dihydroxyvitamin D3. This is sometimes referred to as 'soltriol', which means 'hormone of sunlight'. Only about 15 per cent of the available 7-dehydrocholesterol in the skin actually becomes vitamin d3, as prolonged exposure to the sun converts pre-vitamin D3 into substances called lumisterol and tachysterol, which are both biologically inert." - Richard Hobday PhD, The Healing Sun: Sunlight and Health in the 21st Century (Get the book.)

"Pre-vitamin D is made in the liver, and ultraviolet B sunlight plus heat twist the pre-vitamin D in a reaction that forms vitamin d3 in the skin. When it's further activated in the liver and again in the kidneys and other tissues, it turns into a potent hormone. You can't make any of the active forms of vitamin D without the UVB step. Many forms of active vitamin D exist—some are more potent than others—and they all serve slightly different cell functions. A mixture of different forms of vitamin D is what's doing the work in your body." - James Dowd and Diane Stafford, The Vitamin D Cure (Get the book.)

"The Women's Health Initiative (WHI) followed 36,282 premenopausal women ages fifty to seventy-nine who were randomly assigned to receive 1,000 mg of calcium with 400 IU of vitamin d3 or placebo daily for seven years to assess bone fracture. Supplementation did not reduce the risk of hip fracture. Although there was an increase in hip-bone density, there was also an increase in kidney stones." - J. Douglas Bremner, Before You Take that Pill: Why the Drug Industry May Be Bad for Your Health (Get the book.)

"For maintenance I recommend: v vitamin d3,2,000 IU (This is in addition to what is in your multivitamin, because so many people are significantly vitamin D—deficient.) However, there are many things to keep in mind as you take vitamin D. Special Considerations for Vitamin D 1. Take the right type of vitamin D. • ;?Take only vitamin D, in the active form (cholecalciferol). Look for this type. -I- Many vitamins and prescriptions of vitamin D have vitamin D2, which is not biologically active. 2. For deficiencies you may need more vitamin D." - Mark Hyman MD, The UltraMind Solution: Fix Your Broken Brain by Healing Your Body First (Get the book.) "For examplejust a little vitamin D3"" prevents rickets, but a higher dose may have a role in treating or preventing heart disease, osteoporosis, tuberculosis, multiple sclerosis, polycystic ovarian syndrome, depression, epilepsy, type 1 diabetes, and cancer. Folate not only prevents dementia, but also depression, colon and breast cancer, birth defects, Down syndrome, and more. Magnesium plays a role in over three hundred enzyme reactions. That's only three vitamins and minerals! Imagine the havoc suboptimal levels of many or all of the nutrients I listed on pages 118?" - Mark Hyman MD, The UltraMind Solution: Fix Your Broken Brain by Healing Your Body First (Get the book.)

"Other nutrients in the bone-building team include: vitamin B6, vitamin B9, vitamin B12, vitamin d3, vitamin C, and trace minerals boron, magnesium, calcium, silicon, copper and zinc. Another essential bone-building nutrient is vitamin Osteoporosis is estimated to affect about 75 ^ . A. .... r i ?r ;,r, K2, a nutrient that is not easy million people in Europe, the USA and japan. ' to serve up on your plate. Vitamin K and Bone Health There are two types of vitamin K involved in your bone health." - Allison Tannis, Probiotic Rescue: How You can use Probiotics to Fight Cholesterol, Cancer, Superbugs, Digestive Complaints and More (Get the book.)

"If you don't live in the sun belt or high in the mountains where UBV rays are more potent, you might want to consider 185 taking cod-liver oil, which contains naturally occurring vitamin d3. After the summer months, you can derive naturally occurring vitamin d3 from organ meats, eggs, and fish. Do not supplement with synthetic vitamin D2 (ergocalciferol). Did you know that in primitive cultures around the world where they eat directly from the earth and the sea, they have very few problems with skin cancer or melanoma?" - Timothy Brantley, The Cure: Heal Your Body, Save Your Life (Get the book.)

"Your best long-term replacement form isn't vitamin D2, though, because research suggests that this is less potent than vitamin d3. You can take your vitamin D once a week or only on certain days as long as your weekly total is based on your needs. For example, if you need 3,000 IU a day, you can take 21,000 IU once a week or 4,000 IU five days a week for a total of 20,000 IU. The difference of 1,000 IU for the week is negligible. For any extended period of time, you shouldn't need any more than 40 units per pound or 85 units per kilogram." - James Dowd and Diane Stafford, The Vitamin D Cure (Get the book.)

"Breitman and He, 1990; reviewed by Linder, 1991:494 Vitamin D3 The active metabolite of vitamin d3, 1,2 5-dihydroxy vitamin d3 (l,25-diOHD3), induces differentiation in a variety of cell lines. However, like retinoic acid, it can be toxic at high levels. Retinoic acid appears to up-regulate vitamin d3 receptors and, in this manner, the two compounds may act synergistically. l,25-diOHD3 also induces differentiation in myelocytes (precursors of leukocytes in the bone marrow), affects lymphocyte function, and induces differentiation in epidermal cells." - John Boik, Cancer & Natural Medicine: A Textbook of Basic Science and Clinical Research (Get the book.)

"You'll also want a multivitamin formula that includes vitamin d3, and make sure the vitamin E is in the form of d-alpha-tocopherol. Avoid the "dl" form, which is synthetic. You'll want a high-potency vitamin C (about 1,000 mg) provided by ascorbic acid. An additional form of vitamin C, ascorbyl palmitate, which is a fat-soluble antioxidant, can enhance the formula. You might also find antioxidant complexes with ingredients such as grapeseed extract, pine bark, blueberry extract, zeaxanthin, and astaxanthin." - Brenda Watson and Leonard Smith, The Detox Strategy: Vibrant Health in 5 Easy Steps (Get the book.)

"When a single dose of either vitamin D2 or vitamin d3 was administered, 25(OH)D2 was shown to remain in blood for a much shorter time than the 25(OH)D3, declining after 1 week [17]. Further research is needed to determine the relative contribution of ergocalciferol to vitamin D status. A recent study [12] sought to determine whether provision of the substrate, cholecalciferol, for synthesis of 25(OH)D was rate-limiting." - Ann M. Coulston and Carol J. Boushey, Nutrition in the Prevention and Treatment of Disease (Get the book.)

"We also take in vitamin D orally via fortified foods and milk, but it must then be converted to its biologically active form, vitamin d3. Often the impaired conversion of vitamin D to vitamin d3 may be more of a problem than deficient intake. This is why I recommend supplementation of vitamin D by using the active form, D3. The New England Journal of Medicine reported a study in which researchers looked at the level of vitamin D in 290 consecutive patients admitted to the medical ward of Massachusetts General Hospital." - Ray D. Strand, What Your Doctor Doesn't Know About Nutritional Medicine May Be Killing You (Get the book.)

"The term vitamin D really represents all compounds having or potentially having the activity that we associate with the active metabolite of vitamin D; however, in nutrition we also refer to the precursor molecules provided in the diet or in supplements, which are cholecalciferol (for vitamin d3) and ergo-calciferol (for vitamin D2), as "vitamin D." Generic use of the term vitamin D is a source of great confusion. Through this chapter, an attempt has been made to use the exact term for each metabolite in order to prevent confusion. Table 1 can be used as a guide for this purpose." - Ann M. Coulston and Carol J. Boushey, Nutrition in the Prevention and Treatment of Disease (Get the book.)

"The vitamin D measured in blood tests (25 hydroxy vitamin d3) has about a two-and-a-half-month half-life, meaning that half of it is gone in two to three months. This form of vitamin D is a reflection of your sun exposure, diet, and activity level. Your question refers to lasting benefit. Benefit does carry over, especially if your vitamin D levels were normal (50 to 70) during the first twenty years of your life." - James Dowd and Diane Stafford, The Vitamin D Cure (Get the book.)

"Supplementation with vitamin d3 may be needed. Food sources: fortified milk, salmon, sardines, and mackerel. Forms in the body: cholecalciferol, calcidiol, and calcitriol. Milk is fortified with the addition of 400 IU of vitamin D2 to each quart in the United States. Other dairy products are not normally fortified. Margarine may be fortified with Vitamin D. Toxicity of Vitamin It is important to note that vitamin D created from sunlight on skin is not known to result in toxic levels. Levels of vitamin D produced from sunlight are self-adjusting." - Dr. Steve Blake, Vitamins and Minerals Demystified (Get the book.)

"Monitor your vitamin d3 levels, and have bone density scans if applicable. A supplement with calcium, vitamin d3, and vitamin K2 (such as Jarrow Formulas Bone Up™) is advised for bone health. Take 1-2 enzyme lactase tablets before each meal that contains lactose.

"As a supplement, Vitamin D comes in two forms: ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). vitamin d3 is the natural form, identical to that produced by your body when it is exposed to sunshine. Most prescription vitamin D is the synthetic form. Recent studies have shown it to be considerably less effective. Make sure you are only prescribed vitamin D as D3 (cholecalciferol)." - James Occhiogrosso, N. D., Your Prostate, Your Libido, Your Life (Get the book.)

"This form requires conversion by the liver and kidneys before it becomes fully active. o vitamin d3 (cholecalciferol) - synthesized in the skin in response to exposure to the sun's ultraviolet rays. o Vitamin D5 - a synthetic form of vitamin D Vitamin D3 is considered the natural form of vitamin D and is the most active. Most beneficial when taken with vitamin A, vitamin C, calcium, and phosphorus." - Dr. David W. Tanton; Ph.D., A Drug-Free Approach To Healthcare, Revised Edition (Get the book.)

"If your vitamin D level is below 50ng/ml, take at least 2,000 IUs of vitamin d3 daily. And know that this means you are not getting enough sun! So it's also a good idea to make a real effort to get outside and feel the sun on your face (not at peak hours). Re-check your vitamin D level in three to four months. 2. If your DHEA is below 100, you may want to try taking a DHEA supplement. But before starting DHEA, I recommend trying some licorice root if your blood pressure is low. Licorice root is almost the perfect antidote for tired adrenals (a common cause of Spent and low DHEA)." - Frank Lipman, Mollie Doyle, Spent: Revive: Stop Feeling Spent and Feel Great Again (Get the book.)

"Those over 50 should take 1,000 IU (International Units of vitamin d3) a day. 5. Omega-3 fatty acids. You can fulfill your daily requirement by consuming one tablespoon of flaxseed meal each day—perhaps sprinkling it over cereal. Be sure to refrigerate ground flaxseed. 6. Cholesterol-lowering drugs. These must be taken under a physician's supervision. My own preference is one of the statin cholesterol-lowering drugs, which should be started when you begin the nutrition program." - Caldwell B.
