Phosphatidylserine (PS) is a phospholipid that is found in all cells, but is most highly concentrated in the walls (membranes) of brain cells, making up about 70% of its nerve tissue mass. There it aids in the storage, release and activity of many vital neurotransmitters and their receptors. Phosphatidylserine also aids in cell-to-cell communication.

The idea, or ideal, of a purer nutritional lifestyle practiced by more technology-ignorant communities is tempting when you think of all the chemicals and artificial additives poured into our food and all the really good food we overlook.

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.

Teenage girls and elderly women living in northern Europe have low winter vitamin D status. Andersen R, Mølgaard C, Skovgaard LT, Brot C, Cashman KD, Chabros E, Charzewska J, Flynn A, Jakobsen J, Kärkkäinen M, Kiely M, Lamberg-Allardt C, Moreiras O, Natri AM, O'brien M, Rogalska-Niedzwiedz M, Ovesen L. Eur J Clin Nutr. 2005 Apr;59(4):533-41. PMID: 15714215 doi:10.1038/sj.ejcn.1602108 CONCLUSION: Vitamin D status is low in northern Europe during winter. More than one-third of the adolescent girls have vitamin D status below 25 nmol/l and almost all are below 50 nmol/l. Two-thirds of the elderly community-dwelling women have vitamin D status below 50 nmol/l. Use of vitamin D supplements is a significant positive determinant for S-25OHD for both girls and women (P = 0.001).

The importance of calcium, potassium, and acid-base homeostasis in bone health and osteoporosis prevention. Tylavsky FA, Spence LA, Harkness L. J Nutr. 2008 Jan;138(1):164S-165S. PMID: 18156418 In concert with the acid-base literature, protein intake is considered to be a net acid-producing substance and thus a net negative risk factor for bone dissolution. However, substantial literature supports the beneficial effects on skeletal metabolism when higher protein levels are consumed in concert with adequate calcium, potassium, and other minerals, regardless of the source of protein (24-26). The Dietary Approaches to Stopping Hypertension (DASH) diet (27) is a calcium-rich diet that emphasizes fruits, vegetables, and low-fat dairy products. This diet underscores the importance of consuming a complement of foods from meats, grains, dairy, fruits, and vegetables as prudent for promoting optimal bone health. In the following articles, Rafferty and Lanham-New carefully review the evidence on the interaction of specific diet components that impact bone health and conclude that a balanced diet with recommended servings of dairy products and a variety of fruits and vegetables is prudent for optimal bone health. Additionally, they comment on future research directions for consideration by the scientific community.

The material presented on this site comes from individuals with years of hard-won experience either practicing alternative diets or observing those who do. As you'll find, no two writers will necessarily agree on all topics. A unifying theme, however, is the intent to squarely acknowledge and discuss the sometimes serious problems that can occur on alternative diets but often go unreported, and to go beyond the simplistic dogmas readily available elsewhere--in fact almost everywhere--to "explain them away." A sense of admirable idealism is often a motivating factor encouraging people to take responsibility for their own health and to explore different diets. However, the development of emotional attachments to philosophies underlying such diets can often end up becoming far more important for some individuals than the results they obtain--or fail to. One result has been widespread refusal in the alternative diet community to face health and behavioral problems that may arise on these diets. A common thread in what you'll read here is that a kind of subjective, "blinded naturalism" has become more or less endemic in the vegetarian, raw-food, and alternative diet movements, which can lead to serious health troubles.

One doesn't need to plunge far into the vitamin community to hear one thing or another about the B vitamins. They are perhaps the most well-known of the vitamin supplements.

"Had enough about reading/hearing about Vitamin D? Well, it keeps on coming. And for my lack of surprise, the medical community in general is not catching on like wild fire. I really don't understand it. A recent study from the Heart Institute at Intermountain Medical Center in Salt Lake City (click) followed 27,686 patients greater than 50 years of age with no prior history of cardiovascular disease. The Vitamin D levels were checked and classified as such: * normal - greater than 30 ng/ml * low - 15 to 30 * very low - less than 15 The results of the study showed that patients with very low Vitamin D levels in comparison to normal had: * 77% greater risk of death * 45% increased risk of coronary artery disease * 78% increased risk of stroke * twice the risk of developing heart failure"

"(NaturalNews) New research published in The Journal of the Federation of American Societies for Experimental Biology (FASEB) has found that the "Western" diet, typically high in sugar and fat, may be responsible for activating genes that signal the body to become fatter. According to scientists, the body's response to high amounts of energy-dense food is to activate the kappa opioid receptor which triggers increased fat storage. Researchers arrived at this conclusion by conducting an experiment on two groups of mice. One group had its kappa opioid receptors genetically deactivated while the other remained intact. Both groups were fed diets high in fat and sugar for 16 weeks. At the end of 16 weeks, the group with the deactivated receptor remained lean while the control group gained significant weight. Besides limiting their bodies' ability to store energy-dense food in their fat stores, the mice whose receptors had been deactivated were noted to also have a limited ability to assimilate and store nutrients from the foods they ingested. Traci Ann Czyzyk-Morgan, one of the study's researchers, indicated that the findings prove the hypothesis long held by many in the scientific community that the kappa opioid receptor may be responsible for causing widespread obesity in Western countries. She and others continue to encourage people to avoid diets high in fat and sugar. "

"The US Food and Drug Administration has advised consumers that certain vitamin supplements "can be useful", stating that "there are many good reasons" to consider taking them. The consumer advisory, released this week in video and text format, comes at a time of increased pressure on the supplements industry, with media outlets repeatedly questioning the usefulness and safety of dietary supplements. "Supplements can be useful when they fulfill a specific identified nutrient need that can't be met by food or is not being met through normal food intake," said Barbara Schneeman, PhD, director of FDA's Office of Nutritional Products, Labeling, and Dietary Supplements. The message is one that dietary supplement trade groups have consistently tried to get across, with campaigns such as CRN's Life…supplemented set up to communicate the importan Vitamins for the right reasons According to FDA's consumer update - Fortify Your Knowledge About Vitamins - there are many good reasons to consider taking vitamin supplements, which could be recommended by a doctor in a number of situations, including: * For certain health problems * When following a vegetarian or vegan diet * When pregnant or breastfeeding Iron and folic acid are important for pregnant women or women of childbearing age, to be consumed via a varied diet or from fortified foods and supplements, says FDA. People over 50 should consume vitamin B12, and those with darker skin or with insufficient exposure to sunlight should consume extra vitamin D, again via fortified foods or supplements."
