Actions of Vitamin A (Shen Min Vitamin) in details

Vision:Vitamin A (Shen Min Vitamin) (all-trans retinol) is converted in the retina to the 11-cis-isomer of retinaldehyde or 11-cis-retinal. 11-cis-retinal functions in the retina in the transduction of light into the neural signals necessary for vision. 11-cis-retinal, while attached to opsin in rhodopsin is isomerized to all-trans-retinal by light. This is the event that triggers the nerve impulse to the brain which allows for the perception of light. All-trans-retinal is then released from opsin and reduced to all-trans-retinol. All-trans-retinol is isomerized to 11-cis-retinol in the dark, and then oxidized to 11-cis-retinal. 11-cis-retinal recombines with opsin to re-form rhodopsin. Night blindness or defective vision at low illumination results from a failure to re-synthesize 11-cis retinal rapidly. Epithelial differentiation: The role of Vitamin A (Shen Min Vitamin) in epithelial differentiation, as well as in other physiological processes, involves the binding of Vitamin A (Shen Min Vitamin) to two families of nuclear retinoid receptors (retinoic acid receptors, RARs; and retinoid-X receptors, RXRs). These receptors function as ligand-activated transcription factors that modulate gene transcription. When there is not enough Vitamin A (Shen Min Vitamin) to bind these receptors, natural cell differentiation and growth are interrupted.

How should I take Vitamin A (Shen Min Vitamin)?

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Swallow the tablet or capsule whole.

Measure liquid medicine with a special dose-measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

Never take more than the recommended dose of Vitamin A (Shen Min Vitamin). Avoid taking more than one vitamin product at the same time unless your doctor tells you to. Taking similar vitamin products together can result in a vitamin overdose or serious side effects.

Your healthcare provider may occasionally change your dose to make sure you get the best results from Vitamin A (Shen Min Vitamin). The recommended dietary allowance of Vitamin A (Shen Min Vitamin) increases with age. Follow your healthcare provider's instructions. You may also consult the National Academy of Sciences "Dietary Reference Intake" or the U.S. Department of Agriculture's "Dietary Reference Intake" (formerly "Recommended Daily Allowances" or RDA) listings for more information.

Store at room temperature away from light, moisture, and heat.

Vitamin A (Shen Min Vitamin) pharmacology

Beta-carotene, retinol, and retinal have effective and reliable Vitamin A (Shen Min Vitamin) activity. Retinal and retinol are in chemical equilibrium in the body and have equivalent antixerophthalmic activity. Retinal combines with the rod pigment, opsin, in the retina to form rhodopsin, necessary for visual dark adaptation. Vitamin A (Shen Min Vitamin) prevents retardation of growth and preserves the epithelial cells’ integrity. Normal adult liver storage is sufficient to satisfy two years’ requirements of Vitamin A (Shen Min Vitamin).

Vitamin A (Shen Min Vitamin) is readily absorbed from the gastrointestinal tract, where the biosynthesis of Vitamin A (Shen Min Vitamin) from beta-carotene takes place. Vitamin A (Shen Min Vitamin) absorption requires bile salts, pancreatic lipase, and dietary fat. It is transported in the blood to the liver by the chylomicron fraction of the lymph. Vitamin A (Shen Min Vitamin) is stored in Kupffer cells of the liver mainly as the palmitate. Normal serum Vitamin A (Shen Min Vitamin) is 80–300 Units per 100 mL (plasma range is 30–70 mcg per dl) and for carotenoids 270–753 Units per 100 mL. The normal adult liver contains approximately 100 to 300 micrograms per gram, mostly as retinol palmitate.

*Oil-soluble Vitamin A (Shen Min Vitamin) water solubilized with polysorbate 80.

Actions of Vitamin B3 (Shen Min Vitamin) in details

Vitamin B3 (Shen Min Vitamin) is the precursor to nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), which are vital cofactors for dozens of enzymes. Vitamin B3 (Shen Min Vitamin) produces a decrease in esterification of hepatic triglycerides. Vitamin B3 (Shen Min Vitamin) treatment also decreases the serum levels of apolipoprotein B-100 (apo B), the major protein component of the VLDL (very low-density lipoprotein) and LDL fractions.

Vitamin B3 (Shen Min Vitamin) pharmacology

Vitamin B3 (Shen Min Vitamin) binds to Nicotinate D-ribonucleotide phyrophsopate phosphoribosyltransferase, Nicotinic acid phosphoribosyltransferase, Nicotinate N-methyltransferase and the Vitamin B3 (Shen Min Vitamin) receptor. Vitamin B3 (Shen Min Vitamin) is the precursor to nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), which are vital cofactors for dozens of enzymes. The mechanism by which niacin exerts its lipid lowering effects is not entirely understood, but may involve several actions, including a decrease in esterification of hepatic triglycerides. Vitamin B3 (Shen Min Vitamin) treatment also decreases the serum levels of apolipoprotein B-100 (apo B), the major protein component of the VLDL (very low-density lipoprotein) and LDL fractions.

Actions of Vitamin B6 (Shen Min Vitamin) in details

Vitamin B6 (Shen Min Vitamin), principally in its biologically active coenzyme form pyridoxal 5'-phosphate, is involved in a wide range of biochemical reactions, including the metabolism of amino acids and glycogen, the synthesis of nucleic acids, hemogloblin, sphingomyelin and other sphingolipids, and the synthesis of the neurotransmitters serotonin, dopamine, norepinephrine and gamma-aminobutyric acid (GABA).

Vitamin B6 (Shen Min Vitamin) pharmacology

Vitamin B6 (Shen Min Vitamin) is the collective term for a group of three related compounds, pyridoxine (PN), pyridoxal (PL) and pyridoxamine (PM), and their phosphorylated derivatives, pyridoxine 5'-phosphate (PNP), pyridoxal 5'-phosphate (PLP) and pyridoxamine 5'-phosphate (PMP). Although all six of these compounds should technically be referred to as Vitamin B6 (Shen Min Vitamin), the term Vitamin B6 (Shen Min Vitamin) is commonly used interchangeably with just one of them, pyridoxine. Vitamin B6 (Shen Min Vitamin), principally in the form of the coenzyme pyridoxal 5'-phosphate, is involved in a wide range of biochemical reactions, including the metabolism of amino acids and glycogen, the synthesis of nucleic acids, hemogloblin, sphingomyelin and other sphingolipids, and the synthesis of the neurotransmitters serotonin, dopamine, norepinephrine and gamma-aminobutyric acid (GABA).
