Are You Getting As Much Vitamin D3 As Your Body Really Needs?

Posted |

Our ancestors, in many cases, lived in sunny tropical areas and didn’t wear a whole lot of clothes. Since sunlight falling on exposed skin causes human bodies to generate D-complex vitamins internally, these ancient folks probably didn’t suffer too much from Vitamin-D deficiency.

Fast-forward to modern North American life, where most of Canada and the upper tier of American states have dark, cold, snowy winters lasting several months of the year; and comfort, social conformity, and ‘decency’ motivates people to wear clothing over most of their bodies even during warmer weather. Unsurprisingly, Vitamin-D deficiency has emerged in these sometimes-cold areas as a widespread health problem.

How much sunlight exposure people need, in order to obtain adequate amounts of Vitamin-D complex, varies greatly according to the colors of their skins and how much sunscreen lotion they apply to their bodies. Some sunscreen lotion, for light-skinned people, can help them to ward off skin cancers.

This D-complex-vitamin-generation-from-sunlight-exposure process actually occurs in two distinct phases: First. a precursor biochemical is generated when the sunlight hits human skin. Second, human livers and kidneys filter this precursor biochemical out of human bloodstreams, convert it to actual D-complex vitamins, and reintroduce these back into the bloodstreams to carry them to the various bodily organs and structures that need them in order to operate and to develop properly.

Strictly speaking, Vitamin-D complex isn’t a vitamin; it’s actually a whole group of fat-soluble steroid hormones that help human bodies to regulate their nervous systems and to digest and assimilate calcium, iron, magnesium, phosphates, and zinc. Of this group of steroids, the two most critical to human health are Vitamin D2 and Vitamin D3 — the latter being the most crucial bio compound in the entire group.

Vitamins D2 and D3 don’t occur naturally in very many common foods, at least in large enough amounts to make any serious nutritional difference. A few foods that do contain some Vitamin D2 and Vitamin D3 are: some mushrooms, alfalfa sprouts, egg yolks, beef liver, and fatty cold-salt-water fish such as salmon, tuna, mackerel, sardines, halibut, sablefish, and cod. Cod-liver oil is a traditional American dietary supplement, fed to many folks when they were children even when they resisted.

However, it has become common practice today to fortify milk, cheeses, yogurt, and other dairy products with considerable Vitamin D2 and Vitamin D3; also, many breakfast cereals; orange juice, and other fruit juices and fruit drinks; soy-protein-based beverages; meal-replacement energy bars; some bread products; and infant formula.

There’s apparently no consensus among nutritional experts as to how much daily Vitamin-D complex a human body needs. Expert opinions range from a low of 600 International Units (IUs) daily to 8,000 IUs daily. Some folks favor a dose of 50,000 IU once a week, which at least apparently isn’t seen by most medical practitioners as harmful — unless that amount is taken daily and continued for at least several months. Overdosing on Vitamin D is theoretically possible, but doing so requires taking some action as drastic as eating a lot of polar-bear liver – which some Inuit’s have been known to do, with often fatal consequences.
Some nutritional experts even flatly recommend that everyone who lives in the sometimes-snowy northern areas MUST take a Vitamin-D supplement.

It is usually agreed that older people need somewhat more Vitamin D than do younger people, in order to avoid osteoporosis and osteomalacia — weakened bones, which may get broken during falls; and perhaps also to help to ward off developing multiple sclerosis, rheumatoid arthritis, chronic pain, diabetes, high blood pressure, obesity, cardiovascular disease, depression, and even some cancers. Not all authorities accept some or all of these alleged beneficial effects, however.

As previously stated, it’s been estimated by some nutritional experts that human bodies need about 8,000 IU of Vitamin D per day, although some other authorities have put that daily need at 4,000 IU. One CLE Holistic Health Vitamin D3 gelatin capsule provides 5,000-IU of the needed amount, and most folks are getting some Vitamin D from sunshine, and perhaps from eating seafood and egg yolks and beef liver. CLE Vitamin D gel caps also contain several dozen trace minerals. Like other CLE herbal products, it’s prepared from sources that have been raised organically on CLE’s own farmland plots, and then harvested and processed and packaged using CLE’s proprietary methods, with CLE employees doing the work at every step of the way, in order to maintain excellent control of quality, purity, and uniformity. It’s not known to interact with prescription medicines, so you can try it out without otherwise changing your medicinal regimen. So, isn’t CLE Holistic Health Vitamin D3 a product that you should be looking into?
