L-lysine description

L-Lysine (abbreviated as Lys or K) is an α-amino acid with the chemical formula HO2CCH(NH2)(CH2)4NH2. This amino acid is an essential amino acid, which means that humans cannot synthesize it. Its codons are AAA and AAG. L-Lysine is a base, as are arginine and histidine. The ε-amino group often participates in hydrogen bonding and as a general base in catalysis. Common posttranslational modifications include methylation of the ε-amino group, giving methyl-, dimethyl-, and trimethyllysine. The latter occurs in calmodulin. Other posttranslational modifications include acetylation. Collagen contains hydroxylysine which is derived from lysine by lysyl hydroxylase. O-Glycosylation of lysine residues in the endoplasmic reticulum or Golgi apparatus is used to mark certain proteins for secretion from the cell.

L-lysine side effects

Nausea, Abdominal cramp, Diarrhoea

What is Vitamin B12?

Cyanocobalamin is a man-made form of vitamin B12. Vitamin B12 is important for growth, cell reproduction, blood formation, and protein and tissue synthesis.

Cyanocobalamin is used to treat vitamin B12 deficiency in people with pernicious anemia and other conditions.

Cyanocobalamin may also be used for purposes not listed in this medication guide.

Vitamin B12 indications

Pernicious anemia, both uncomplicated and accompanied by nervous system involvement.

Dietary deficiency of Vitamin B12, occurring in strict vegetarians and in their breast-fed infants. (Isolated vitamin B12 deficiency is very rare).

Malabsorption of vitamin B12, resulting from structural or functional damage to the stomach, where intrinsic factor is secreted or to the ileum, where intrinsic factor facilitates vitamin B12 absorption. These conditions include tropical sprue, and nontropical sprue (idiopathic steatorrhea, gluten-induced enteropathy). Folate deficiency in these patients is usually more severe than vitamin B12 deficiency.

Inadequate secretion of intrinsic factor, resulting from lesions that destroy the gastric mucosa (ingestion of corrosives, extensive neoplasia), and a number of conditions associated with a variable degree of gastric atrophy (such as multiple sclerosis, certain endocrine disorders, iron deficiency, and subtotal gastrectomy). Total gastrectomy always produces vitamin B12 deficiency.

Structural lesions leading to vitamin B12 deficiency include regional ileitis, ileal resections, malignancies, etc.

Competition for Vitamin B12 by intestinal parasites or bacteria.

The fish tapeworm (Diphyilobothrium latum) absorbs huge quantities of vitamin B12 and infested patients often have associated gastric atrophy. The blind-loop syndrome may produce deficiency of Vitamin B12 or folate.

Inadequate utilization of vitamin B12. This may occur if antimetabolites for the vitamin are employed in the treatment of neoplasia.

For the Schilling Test.

Vitamin B12 description

Vitamin B12 (commonly known as Vitamin B12) is the most chemically complex of all the vitamins. Vitamin B12's structure is based on a corrin ring, which, although similar to the porphyrin ring found in heme, chlorophyll, and cytochrome, has two of the pyrrole rings directly bonded. The central metal ion is Co (cobalt). Vitamin B12 cannot be made by plants or by animals, as the only type of organisms that have the enzymes required for the synthesis of cyanocobalamin are bacteria and archaea. Higher plants do not concentrate cyanocobalamin from the soil and so are a poor source of the substance as compared with animal tissues. Vitamin B12 is naturally found in foods including meat (especially liver and shellfish), eggs, and milk products.

Vitamin B12 dosage

Vitamin B12 is used as injections SC, IV, IM, intralumbar, and also oral. With anemia associated with vitamin B12 deficiency is introduced on 100-200 mcg in 2 days. In anemia with symptoms of funicular myelosis and megalocytic anemia with diseases of the nervous system - 400-500 micrograms in the first 7 days daily, then 1 time every 5-7 days. In the period of remission in the absence of events funicular myelosis maintenance dose - 100 mcg 2 times a month, in the presence of neurological symptoms - at 200-400 mcg 2-4 times a month. In acute post-hemorrhagic anemia and iron anemia by 30-100 mcg 2-3 times a week. When aplastic anemia (especially in children) - 100 micrograms before clinical improvement. When nutritional anemia in infants and preterm - 30 mcg / day during 15 days.

In diseases of the central and peripheral nervous system and neurological diseases with a pain syndrome is administered in increasing doses - 200-500 mcg, with the improvement in the state - 100 mcg / day. The course of treatment with Vitamin B12 is 2 weeks. In traumatic lesions of peripheral nervous system - at 200-400 mcg every other day for 40-45 days.

When hepatitis and cirrhosis - 30-60 mcg / day or 100 mg every other day for 25-40 days.

Dystrophy in young children, Down syndrome and cerebral palsy - by 15-30 mcg every other day.

When funicular myelosis, amyotrophic lateral sclerosis can be introduced into the spinal canal at 15-30 mcg, gradually increasing the dose of 200-250 micrograms.

In radiation sickness, diabetic neuropathy, sprue - by 60-100 mcg daily for 20-30 days.

When deficiency of vitamin B12 to prevent - IV or IM for 1 mg 1 time a month; for treatment - IV or IM for 1 mg daily for 1-2 weeks, the maintenance dose is 1-2 mg IV or IM from 1 per week, up to 1 per month. Duration of treatment is determined individually.

Vitamin B12 interactions

In an application of Vitamin B12 Atlantic Laboratories with hormonal contraceptives for oral administration may decrease the concentration of cyanocobalamin in plasma.

In an application with anticonvulsant drugs decreased cyanocobalamin absorption from the gut.

In an Vitamin B12 Atlantic Laboratories application with neomycin, aminosalicylic acid, colchicine, cimetidine, ranitidine, drugs potassium decreased cyanocobalamin absorption from the gut.

Uses of Vitamin B6 in details

It is used for the treatment and prevention of vitamin B6 deficiency. It is important for the breakdown of protein, fats, and carbohydrates from foods.

Vitamin B6 description

The 4-methanol form of vitamin B 6 which is converted to pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990).

Vitamin B6 interactions

Interactions for vitamin B6

Amiodarone: Concomitant use of vitamin B6 and amiodarone may enhance amiodarone-induced photosensitivity reactions. Doses of vitamin B6 greater than 5-10 milligrams/day should be avoided by those taking amiodarone Carbamazepine: Chronic use of carbamazepine may result in a significant decrease in plasma pyridoxal 5-phosphate levels Cycloserine: Cycloserine may react with pyridoxal 5-phosphate to form a metabolically inactive oxime, which may result in a functional vitamin B6 deficiency Ethionamide: The use of ethionamide may increase vitamin B6 requirements Fosphenytoin: High doses of vitamin B6 may lower plasma levels of phenytoin. Fosphenytoin is a prodrug of phenytoin Hydralazine: The use of hydralazine may increase vitamin B6 requirements Isoniazid: (isonicotinic acid, INH). Isoniazid reacts with pyridoxal 5-phosphate to form a metabolically inactive hydrazone, which may result in functional vitamin B6 deficiency Levodopa: Concomitant use of levodopa and vitamin B6 in doses of 5 milligrams or more daily may reverse the therapeutic effects of levodopa. Vitamin B6 does not reverse the therapeutic effects of levodopa if levodopa is taken concurrently with the levodopa decarboxylase inhibitor carbidopa. Levodopa is typically administered as a combination product with carbidopa

Oral contraceptives: The use of oral contraceptives may increase vitamin B6 requirements. This was more the case with the older oral contraceptive agents with high-dose estrogen/progestin. It appears to be less the case with the newer low-dose estrogen/progestin products Penicillamine: Penicillamine may react with pyridoxal 5-phosphate to form a metabolically inactive thiazolidine, which may result in a functional vitamin B6 deficiency Phenelzine: Phenelzine may react with pyridoxal 5-phosphate to yield a metabolically inactive hydrazone compound Phenobarbital: High doses of vitamin B6 may lower plasma levels of phenobarbital Phenytoin: High doses of vitamin B6 may lower plasma levels of phenytoin Theophylline: Theophylline may react with pyridoxal 5-phosphate leading to low plasma levels of the coenzyme. This may increase the risk of theophylline-induced seizures Valproic acid: Chronic use of valproic acid may result in a significant decrease in plasma pyridoxal 5-phosphate levels.

Vitamin B6 side effects

Applies to pyridoxine: capsule, injectable, solution, tablet, tablet enteric coated, tablet extended release

As well as its needed effects, pyridoxine (the active ingredient contained in Vitamin B6) may cause unwanted side effects that require medical attention.
