A to Z Nutrients
Vitamin D assists absorption and utilization of calcium and phosphorus required for bone formation. It also maintains stable nervous system and normal heart action. Signs of deficiency include poor bone and tooth formation, softening of bones and teeth, inadequate absorption of calcium, and retention of phosphorus in kidney. Recommended amount for infants, children, and adults is 400 IU per day. See updated information at our Vitamin D Topic page.
Dandelion (Taraxacum off.) Blood cleanser; powerful and safe diuretic; for inflammation and congestion of the liver and gall bladder, obstructive jaundice. Mild laxative.
Devil's Club (Oplopanax horridum) Pancreatic tonic, blood sugar regulator, increases endurance
DHEA See DHEA HotTopic
Dill (Anethum graveolens) For flatulence and colic, especially in children; stimulates lactation.
is a natural amino alcohol and a precursor to choline and acetylcholine
in the brain. DMAE naturally occurs in fish, especially sardines, herring
and anchovies. Dr. Carl C. Pfeiffer, M.D., Ph.D. introduced DMAE in 1957
under the trade name Deaner. DMAE by itself is alkaline and caustic, so
only salts and esters of DMAE are used in products. Deaner, a prescription
drug, is the p-acetamidobenzoate salt of DMAE. The bitartrate and PABA
salts of DMAE, which are available in vitamin stores, have the same active
DMAE is reported to elevate mood, increase intelligence, improve memory and learning, and extend lifespan. DMAE also stabilizes lysosome membranes, preventing the uncontrolled leakage of lysosomal enzymes in the cells and the resulting damage of important intracellular organelles. Some researchers suggest that aging may be triggered by leakage of lysosomal enzymes into the cells and surrounding connective tissue as a result of membrane damage. Another theory proposes that aging is due in part to the accumulation of lipofuscin, or age pigment, a yellowish-brown substance that builds up in the skin and brain cells. DMAE can slow the rate of accumulation of lipofuscin and also speed up its removal.
DMAE and the vitamin choline have similar structures; DMAE is choline with one methyl group removed. Both are reported to increase levels of acetylcholine in the brain, but choline must be processed in the liver first, while DMAE can be transported directly across the blood-brain barrier. This explains why DMAE works more consistently when taken to increase concentration and short-term memory. DMAE supplementation is best started with a small amount and increased gradually. A large dose taken before the body gets used to it could result in a temporary condition of muscle stiffness in the neck and shoulders. This almost never happens at typical doses of DMAE, but as a precaution it's best to increase the dose at weekly intervals.
DMG (n,n-Dimethylglycine) is the active nutrient behind what was called B-15, calcium pangamate, or pangamic acid. It is an intermediary metabolite that is useful in the production of neurotransmitters, hormones, DNA, choline, and methionine. It enhances the immune response system, normalizes blood glucose levels and reduces high blood pressure levels. It enhances oxygen utilization, reduces lactic acid formation, and aids detoxification- improving liver, pancreas, and adrenal function. In 1960 Russia reported DMG benefited people suffering from diabetes, alcoholism, mental disorders, and cardiovascular ailments. Also, DMG enhanced athletic performance, as demonstrated by the Olympics. I have found it to have excellent results for increasing my endurance when exercising, sharpening my vision, stopping allergy reactions, and even stopping headaches in the early stages.
