About Beta CaroteneA natural precursor to Vitamin A.Mechanism of Action of Beta CaroteneBeta-carotene acts as the precursor of Vitamin A and in the body it is converted in to Vitamin A. Vitamin A is required for a variety of physiological functions in the body such as: - 1).Proper functioning of retina and formation of pigment Rhodopsin during dark adaptation. 2).promotes differentiation and maintains structural integrity of epithelia over the body and also retard the malignancies of epithelial structures.3).Promotes mucous secretion. 4).Inhibits keratinization, 5). Maintains proper bone growth, 6).Maintenance of spermatogenesis, 7).Supports foetal development, 8).Improves resistance to infection. It is required for proper antibody response, normal lymphocyte proliferation and killer cell function.Pharmacokinets of Beta CaroteneAbsorption: Completely absorbed normally. Steatorrhoea, bile deficiency, and protein poor diet adversely affects the absorption and absorption requires bile salts, pancreatic lipase, and dietary fat.
Distribution: Stored primarily as palmitate in kupffer`s cells in liver. Circulates in the form of specific alpha-1 protein; retinol binding protein and transported to cellular retinol binding protein of target cells.
Metabolism: Metabolized in the liver.
Excretion: Excreted mainly through bile and a small amount is excreted through urine.

About Vit B12N/AMechanism of Action of Vit B12Vitamin B12 is an essential constituent for growth, cell reproduction, hematopoiesis, and nucleoprotein and myelin synthesis. Vitamin B12 is converted in to coenzyme B12 in the tissues which is essential for conversion of methyl-malonate to succinate and synthesis of methionine from homocystine. It is also associated with fat and carbohydrate metabolism and protein synthesis. Cells characterized by rapid division such as epithelial cells, bone marrow, and myeloid cells appear to have greatest requirement of Cyanocobalamin.Pharmacokinets of Vit B12Absorption: Absorbed irregularly after oral administration and absorption depends on Ca and intrinsic factor. It is also administered subcutaneously and intramuscularly.
Distribution: Distributed in to liver, bone marrow, and other tissues. It crosses the placenta and appears in breast milk.
Metabolism: It is metabolized in liver.

About Folic AcidDietary supplement, Folate derivative( B9 ), Water Soluble Vitamin.Mechanism of Action of Folic AcidFolic acid reduced by enzymes folate reductase and dihydrofolate reductase and forms dihydrofolic acid tetrahydrofolic acid respectively. Tetrahydrofolic acid acts as a coenzyme which mediates a number of one carbon transfer reactions by carrying a methyl group as an adduct. It involves a number of reactions such as 1).conversion of homocysteine to methionine. 2).synthesis of thymidylate which is an essential constituent of DNA from methylene-tetrahydrofolic acid. 3). Conversion of serine to glycine by tetrahydrofolic acid and forms methylene-tetrahydrofolic acid. 4).to introduce carbon units at position 2 and 8 during de novo purine synthesis requires formyl-tetrahydrofolic acid and methenyl-tetrahydrofolic acid.5).generation and utilization of "formate pool". 6).For mediating formino group transfer in histidine metabolism. Folic acid is required to maintain normal erythropoiesis and nucleoprotein synthesis.Pharmacokinets of Folic AcidAbsorption: Well absorbed orally
Distribution: Widely distributed in the body and highest concentration is seen in liver. It appears in the CSF and breast milk
Metabolism: Metabolized in to N-methyl tetrahydrofolic acid in liver
