Preeclampsia : Supplements

L-arginine was first isolated in 1886. In 1932, L-arginine was found to be required for the generation of urea, which is necessary for the removal of toxic ammonia from the body. In 1939, L-arginine was also shown to be required for the synthesis of creatine. Creatine degrades to creatinine at a constant rate, and is cleared from the body by the kidney. Arginine is considered a semi-essential amino acid, because although it is normally synthesized in sufficient amounts by the body, supplementation is sometimes required (for example, due to inborn errors of urea synthesis, protein malnutrition, excess ammonia production, excessive lysine intake, burns, infection, peritoneal dialysis, rapid growth, or sepsis). Symptoms of arginine deficiency include poor wound healing, hair loss, skin rash, constipation, and fatty liver. Arginine is a precursor of nitric oxide, which causes blood vessel relaxation (vasodilation). Preliminary evidence suggests that arginine may be useful in the treatment of medical conditions that are improved by vasodilation, such as angina, atherosclerosis, coronary artery disease, erectile dysfunction, heart failure, intermittent claudication/peripheral vascular disease, and vascular headache. Arginine also stimulates protein synthesis and has been studied for wound healing, bodybuilding, enhancement of sperm production (spermatogenesis), and prevention of wasting in people with critical illness. Arginine hydrochloride contains high chloride content and has been used for the treatment of metabolic alkalosis. This use should be under the supervision of a qualified healthcare professional. Most people likely do not need to take arginine supplements because the body usually makes sufficient amounts.

Arginine is one of the amino acids produced in the human body by the digestion, or hydrolysis of proteins. Arginine can also be produced synthetically.

Selenium is a trace mineral found in soil, water, and some foods. It is an essential element in several metabolic pathways. Selenium deficiency can occur in areas where soil content of selenium is low, and may affect thyroid function and cause conditions such as Keshan disease. Selenium deficiency is also commonly seen in patients on total parenteral nutrition (TPN) as their sole source of nutrition. Gastrointestinal disorders may decrease the absorption of selenium resulting in depletion or deficiency. Selenium may be destroyed when foods are refined or processed. Specific dietary sources of selenium include brewer's yeast, wheat germ, butter, garlic, grains, sunflower seeds, Brazil nuts, walnuts, raisins, liver, kidney, shellfish (lobster, oyster, shrimp, scallops), fresh-water and salt-water fish (red snapper, salmon, swordfish, tuna, mackerel, halibut, flounder, herring, smelts). Selenium is also found in alfalfa, burdock root, catnip, fennel seed, ginseng, raspberry leaf, radish, horseradish, onion, chives, medicinal mushrooms (reishi, shiitake), and yarrow. The role of selenium in cancer prevention has been the subject of recent study and debate. Initial evidence from the Nutritional Prevention of Cancer (NPC) trial suggests that selenium supplementation reduces the risk of prostate cancer among men with normal baseline PSA (prostate specific antigen) levels, and low selenium blood levels. However, in this study selenium did not reduce the risk of lung, colorectal, or basal cell carcinoma of the skin, and actually increased the risk of squamous cell skin carcinoma. The ongoing Selenium and Vitamin E Cancer Prevention Trial (SELECT) aims to definitively address the role of selenium in prostate cancer prevention.

Selenium is an essential trace mineral. Small amounts of selenium are good for your health.Selenium has a variety of functions.

Selenium is a nonmetallic element with an atomic number of 34 and an atomic weight of 78.96. Its chemical symbol is Se.

Riboflavin is a water-soluble vitamin, which is involved in vital metabolic processes in the body, and is necessary for normal cell function, growth, and energy production. Small amounts of riboflavin are present in most animal and plant tissues. Healthy individuals who eat a balanced diet rarely need riboflavin supplements. Especially good dietary sources of riboflavin are milk (and other dairy products), eggs, enriched cereals/grains, meats, liver, and green vegetables (such as asparagus or broccoli). Intake may be lower in vegetarians compared to non-vegetarians. Riboflavin is often used as a tracer of medication compliance in the treatment of patients with alcohol dependence, mental disorders, and other conditions. Urinary riboflavin levels may be measured in order to determine level of compliance.

Water-soluble, B complex vitamin.

Riboflavin is a type of B vitamin. It is water soluble, which means it is not stored in the body.

Riboflavin, also known as Vitamin B 2, has many functions in common with the other members of the B complex family. These include support of the immune and nervous systems, and formation of healthy red blood cells.

Riboflavin deficiency occurs when the chronic failure to eat sufficient amounts of foods that contain riboflavin produces lesions of the skin, lesions of smooth surfaces in the digestive tract, or nervous disorders.Riboflavin, also called vitamin ...

Lycopene is a carotenoid, and is present in human serum, liver, adrenal glands, lungs, prostate, colon, and skin at higher levels than other carotenoids. Lycopene has been found to possess antioxidant and antiproliferative properties in animal and in vitro studies, although activity in humans remains controversial. Numerous epidemiological investigations have correlated high intake of lycopene-containing foods or high lycopene serum levels with reduced incidence of cancer, cardiovascular disease, and macular degeneration. However, estimates of lycopene consumption have been based on reported tomato intake, not on the use of lycopene supplements. Since tomatoes are sources of other nutrients including vitamin C, folate, and potassium, it is not clear that lycopene itself is beneficial. There is no established definition of "lycopene deficiency," and no direct evidence that repletion of low lycopene levels has any benefit.

Lycopene is a red, fat-soluble pigment found in vegetables, and most commonly found in tomatoes. It is one of a family of pigments called carotenoids.

Lutein and zeaxanthin are found in high levels in foods such as green vegetables, egg yolk, kiwi fruit, grapes, orange juice, zucchini, squash, and corn. For some commercially available supplements, lutein is extracted from marigold petals. Lutein and zeaxanthin are carotenoids in the macular region of the retina of the eye (macular pigment), and thus lutein has been studied for its use in treating cataracts, preventing macular degeneration and retinal degeneration. Lutein and zeaxanthin also have antioxidant capabilities as well as the ability to trap short-wavelength light. The potential for carotenoids, including lutein, to play a preventing role in cardiovascular disease and cancer was recognized in the 1990s. Most of the information surrounding lutein is based on blood and/or dietary intakes of lutein compared with disease states (e.g. cancer, eye disorders, lung function, muscle soreness, obesity, and pre-eclampsia). More evidence is needed before recommendations can be made in these fields.

Found in certain fruits and vegetables as well as egg yolks, lutein is a nutrient with a number of potentially beneficial effects. It is a member of the carotenoid family, a group of chemicals related to vitamin A.

Dietary sources of omega-3 fatty acids include fish oil and certain plant/nut oils. Fish oil contains both docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), while some nuts (English walnuts) and vegetable oils (canola, soybean, flaxseed/linseed, olive) contain alpha-linolenic acid (ALA). There is evidence from multiple studies supporting intake of recommended amounts of DHA and EPA in the form of dietary fish or fish oil supplements lowers triglycerides, reduces the risk of death, heart attack, dangerous abnormal heart rhythms, and strokes in people with known cardiovascular disease, slows the buildup of atherosclerotic plaques ("hardening of the arteries"), and lowers blood pressure slightly. However, high doses may have harmful effects, such as an increased risk of bleeding. Although similar benefits are proposed for alpha-linolenic acid, scientific evidence is less compelling, and beneficial effects may be less pronounced. Some species of fish carry a higher risk of environmental contamination, such as with methylmercury.

Antilipemic agent; combination consisting predominantly of ethyl esters of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Omega-6 fatty acids are one of two groups of essential fatty acids(EFAs) that are required in human nutrition.(The other is the omega-3 fatty acid group.)

Omega-3 fatty acids are one of two groups of fatty acids—the omega-3s and the omega-6s—that are vital to human life. They are called essential fatty acids(EFAs), which the body cannot make but absolutely needs for normal growth and dev...

Omega-3 EFAs are found in deepwater fish, fish oil, and some vegetable oils, such as canola, flaxseed, and walnut oil. Nuts are also a good source of omega-3 fatty acids, particularly hazelnuts, almonds, pecans, cashews, walnuts, and macadamia nuts.

Gamma linolenic acid (GLA) is a dietary omega-6 fatty acid found in many plant oil extracts. Commercial products are typically made from seed extracts from evening primrose (average oil content 7-14%), blackcurrant (15-20%), borage oil (20-27%) and fungal oil (25%). GLA is not found in high levels in the diet. It has been suggested that some individuals may not convert the omega-6 fatty acid linoleic acid to longer chain derivatives, such as GLA, efficiently. Thus, supplementation with GLA-containing oils, such as borage oil and evening primrose oil, is occasionally recommended to increase GLA levels in the body. GLA is available commonly as a dietary supplement and is sold over the counter in capsules or oil to treat a variety of conditions such as eczema, oral mucoceles (mucus polyps), hyperlipidemia (high cholesterol), depression, postpartum depression, chronic fatigue syndrome (CFS), psoriasis (chronic skin disease), muscle aches, and menopausal flushing. There is currently good evidence for GLA treatment in rheumatoid arthritis, acute respiratory distress syndrome, and diabetic neuropathy (nerve damage). Little or no effect has been found in treatment of atopic dermatitis, attention deficit hyperactivity disorder (ADHD), cancer prevention, menopausal flushing, systemic sclerosis, and hypertension (high blood pressure). GLA has also been used to help with the body's response to tamoxifen in breast cancer patients. Today, production and extraction of oil from evening primrose and borage is done by companies primarily in China, New Zealand, and England. Pharmaceutical licensing for GLA oil products has had only limited success worldwide.

Chinese herbalists have relied on rhubarb rhizomes and roots for thousands of years. The rhizomes and roots contain powerful anthraquinones and tannins that act as stimulant laxatives and astringents, respectively. In traditional Chinese medicine, rhubarb is also used to treat gastric ulcers, chronic renal (kidney) failure, and pregnancy-induced hypertension (high blood pressure), pre-eclampsia and eclampsia. European herbalists have recommended rhubarb as a laxative, diuretic, and to treat kidney stones, gout (foot inflammation), and liver diseases. Externally, it is recommended to heal skin sores and scabs. The current practice of using rhubarb to treat cancer (as an ingredient in the herbal Essiac® formula) lacks the support of controlled clinical trials. However, rhubarb is being tested for multiple other conditions, including hyperlipidemia (high cholesterol) and obesity. Use for gingivitis, chronic renal failure and upper gastrointestinal bleeding seem to be the most promising, although more research should be done in these areas, specifically with rhubarb as a monotherapy.

Rhubarb, also called sweet round-leaved dock or pieplant, is usually thought of as a fruit, but it is actually one of the few perennial vegetables in existence. Ordinary garden rhubarb carries the botanical name of Rheum rhaponticum, though there ...

Evening primrose oil (EPO) contains an omega-6 essential fatty acid, gamma-linolenic acid (GLA), which is believed to be the active ingredient. EPO has been studied in a wide variety of disorders, particularly those affected by metabolic products of essential fatty acids. However, high-quality evidence for its use in most conditions is still lacking.

Evening primrose oil is a dietary supplement derived from the seeds of the evening primrose plant, Oenothera biennis. Its Latin name is derived from the Greek word for wine, reflecting the folk belief that the plant could.relieve the symptoms of a...
