Vitamin K2: Building bones while beating back arterial calcification

Vitamin K2’s time to shine has come—move over vitamin D! Once only known for its role as a “koagulation” factor in blood clotting, vitamin K2 is emerging as another fundamental anti-aging nutrient. While vitamins D and E have garnered the majority of interest in the last decade, the impact of vitamin K2 on aging bonesContinue reading “Vitamin K2: Building bones while beating back arterial calcification”

High doses of B vitamins may slow brain shrinkage and support memory

Unfortunately, getting older comes with a common consequence affecting up to 16 percent of elderly people – gradual reduction in brain size, which is associated with problems in learning and memory. However, a new study reports that daily supplementation with high doses of B vitamins may help slow the rate of brain degeneration. Oxford researchersContinue reading “High doses of B vitamins may slow brain shrinkage and support memory”

Boron and Disease

Boron’s ability to induce sex hormone levels give it a role preventing chronic disease. For example, adequate dietary boron may potentially reduce risk of lung cancer (1). The effects also explain why boron supplementation may support bone density guarding against osteoporosis (2). However, caution should be exercised before supplementation with boron. Greater estrogen levels dueContinue reading “Boron and Disease”

Nickel toxicity

Nickel is a known carcinogen. When in the diet in toxic amounts it contributes to oxidative stress, just as mercury and cadmium do, by reducing glutathione thereby interfering with cell membrane integrity and increasing lipid peroxidation (1). The oxidative damage, like from free iron or copper, can cause DNA damage (2). Reference List 1. ValkoContinue reading “Nickel toxicity”

Flouride and the World

As one travels around the world, especially in developing countries, the state of oral health stands out as an issue that needs attention. Fluoride treatment of drinking water can be an important step in improving oral health (1), but some populations may find it’s not necessary because they may already be consuming adequate or evenContinue reading “Flouride and the World”

Molybdenum and Gout

A young electrician with a painful gouty arthritis in 2005 became the first case observed of occupational exposure of toxic amounts of molybdenum (1). Molybdenum is an activator of xanthine oxidase, which oxidizes xanthine producing uric acid (2). Too much produced hyperuricemia (1). The electrician can be thankful that his doctors found the cause ofContinue reading “Molybdenum and Gout”

Manganese as a Neurotoxin

Toxicity of manganese is more common than its deficiency (1), which unfortunately cause damage to the brain. Manganese appears to cause neurogeneration by activating microglia and causing them to release neurotoxins such as reactive oxygen and nitrogen species, which produce oxidative damage (2). The neurotoxins are also thought to possibly alter influence of neurotransmitters suchContinue reading “Manganese as a Neurotoxin”

Vanadium treatment of type 2 diabetes enhanced by organic ligands

Vanadyl ions can act in an insulin-like manner in the body. Thus, when taken orally they may potentiate insulin’s effects, which can potentially improve situations of type 2 diabetes (1). Bioavailability of vanadyl compounds, however, can depend on whether of organic or inorganic nature (2). The organic bis-ligand oxovanadium appear to be far more bioavailableContinue reading “Vanadium treatment of type 2 diabetes enhanced by organic ligands”

Life Depends on Arsenic?

As Gropper, Smitth and Groff tell it, arsenic “conjures an image of toxicity” unlike any other ultratrace mineral (1), but there are good things that come of arsenic and its story is worth discussion. Without arsenic, DNA synthesis couldn’t happen. This is because arsenic is needed for normal metabolism. Specifically, the mineral is required forContinue reading “Life Depends on Arsenic?”

Chromium and Glucose Tolerance

Because of chromium’s known ability to potentiate action of insulin, an adequate chromium status is important especially for people with diabetes, insulin resistance and hypoglycemia to maintain glycemic control (1;2). According to an evaluation of 15 randomized clinical trials, amounts of about 200 mcg per day appear to improve use of glucose (3). In addition,Continue reading “Chromium and Glucose Tolerance”
