Inositol is a collection of nine different stereoisomers but the name is usually used to describe only the most common type of inositol, myo-inositol. Myo-inositol is the cis-1,2,3,5-trans-4,6-cyclohexanehexol and it is prepared from an aqueous extract of corn kernels by precipitation and hydrolysis of crude phytate. These molecules have structural similarities to glucose and are involved in cellular signaling. It is considered a pseudovitamin as it is a molecule that does not qualify to be an essential vitamin because even though its presence is vital in the body, a deficiency in this molecule does not translate into disease conditions. Inositol can be found as an ingredient of OTC products by Health Canada but all current product whose main ingredient is inositol are discontinued. By the FDA, inositol is considered in the list of specific substances affirmed as generally recognized as safe (GRAS).
Inositol can stimulate glucose uptake in skeletal muscle cells which allows the decrease in blood sugar levels. This effect is later seen as a reduction in urine glucose concentration and indicates a decrease in high blood sugar levels.
In PCOS, the administration of inositol has produced the remission of symptoms as well as a reduction in male hormone secretion, a regulation of the cholesterol level, and a more efficient fat breakdown which allow to a significant reduction on body mass and appetite.
Vitamin E Capsule is a Vitamin E preparation. Vitamin E acts as an antioxidant in the body. Vitamin E protects polyunsaturated fatty acids (which are components of cellular membrane) and other oxygen-sensitive substances such as vitamin A & vitamin C from oxidation. Vitamin E reacts with free radicals, which is the cause of oxidative damage to cell membranes, without the formation of another free radical in the process. The main pharmacological action of vitamin E in humans is its antioxidant effect.
In premature neonates irritability, edema, thrombosis and hemolytic anemia may be caused due to vitamin E deficiency. Creatinuria, ceroid deposition, muscle weakness, decreased erythrocyte survival or increased in vitro hemolysis by oxidizing agents have been identified in adults and children with low serum tocopherol concentrations.
Vitamin E is a collective term used to describe 8 separate fat soluble antioxidants, most commonly alpha-tocopherol. Vitamin E acts to protect cells against the effects of free radicals, which are potentially damaging by-products of the body's metabolism. Vitamin E deficiency is seen in persons with abetalipoproteinemia, premature, very low birth weight infants (birth weights less than 1500 grams, or 3½ pounds), cystic fibrosis, and cholestasis and severe liver disease. Preliminary research suggests vitamin E may help prevent or delay coronary heart disease and protect against the damaging effects of free radicals, which may contribute to the development of chronic diseases such as cancer. It also protects other fat-soluble vitamins (A and B group vitamins) from destruction by oxygen. Low levels of vitamin E have been linked to increased incidence of breast and colon cancer.

Uses
Inositol is an ingredient found in a variety of nutritional products.
Inositol may be used in food without any limitation. As a drug, inositol is used as a nutrient supplement in special dietary foods and infant formula. As it presents a relevant role in ensuring oocyte fertility, inositol has been studied for its use in the management of polycystic ovaries. Inositol is also being researched for the treatment of diabetes, prevention of metabolic syndrome, aid agent for weight loss, treatment of depression, psychiatric disorder and anxiety disorder and for prevention of cancer.
As a dietary supplement:
- Vitamin E deficiency resulting from impaired absorption.
- Increased requirements due to diet rich in polyunsaturated fats.
- For healthy hair & skin
- As an Antioxidant
- Hemolytic anemia due to Vitamin E deficiency
Therapeutic use
: Heavy metal poisoning, Hepatotoxin poisoning, Hemolytic anemia, Oxygen therapy and replacement therapy in nutritional deficiency states for the betterment of skin and hair.
Maitong is also used to associated treatment for these conditions: Vitamin Deficiency, Long-chain omega-3 fatty acid supplementation, Dietary supplementation
How Maitong works
The mechanism of action of inositol in brain disorders is not fully understood but it is thought that it may be involved in neurotransmitter synthesis and it is a precursor to the phosphatidylinositol cycle. The change that occurs in the cycle simulates when the postsynaptic receptor is activated but without activating the receptor. This activity provokes a fake activation which regulated the activity of monoamines and other neurotransmitters.
Reports have shown that insulin resistance plays a key role in the clinical development of PCOS. The presence of hyperinsulinemia can induce an excess in androgen production by stimulating ovaries to produce androgens and by reducing the sex hormone binding globulin serum levels. One of the mechanisms of insulin deficiency is thought to be related to a deficiency in inositol in the inositolphosphoglycans. The administration of inositol allows it to act as a direct messenger of the insulin signaling and improves glucose tissue uptake. This mechanism is extrapolated to its functions in diabetes treatment, metabolic syndrome, and weight loss.
In cancer, the mechanism of action of inositol is not fully understood. It is hypothesized that the administration of inositol increases the level of lower-phosphate inositol phosphates why can affect cycle regulation, growth, and differentiation of malignant cells. On the other hand, the formation of inositol hexaphosphate after administration of inositol presents antioxidant characteristics by the chelation of ferric ions and suppression of hydroxyl radicals.
The mechanism of action for most of vitamin E's effects are still unknown. Vitamin E is an antioxidant, preventing free radical reactions with cell membranes. Though in some cases vitamin E has been shown to have pro-oxidant activity.
One mechanism of vitamin E's antioxidant effect is in the termination of lipid peroxidation. Vitamin E reacts with unstable lipid radicals, producing stable lipids and a relatively stable vitamin E radical. The vitamin E radical is then reduced back to stable vitamin E by reaction with ascorbate or glutathione.
Dosage

Side Effects
Overdoses (>1g) have been associated with minor side effects, including hypertension, fatigue, diarrhea and myopathy
Toxicity
Consumption of high doses of inositol is reported to only cause some gastrointestinal effects.
There is no data available for effects in pregnancy, breast feeding, hepatic impairment, or renal impairment. However, it appears that the process of vitamin E elimination is strict and self regulating enough that vitamin E toxicity is exceedingly rare. Studies showing adverse effects from excess vitamin E generally involve people consuming more than 1000mg/day for weeks to months.
Precaution
Vitamin E may enhance the anticoagulant activity of anticoagulant drugs. Caution is advised in premature infants with high dose Vitamin E supplementation, because of reported risk of necrotizing enterocilitis.
Interaction
Vitamin E may impair the absorption of Vitamin A. Vitamin K functions impairement happens at the level of prothrombin formation and potentiates the effect of Warfarin.
Volume of Distribution
The pharmacokinetic profile of inositol was studied in preterm infants and the estimated volume of distribution was reported to be 0.5115 L/kg.
0.41L/kg in premature neonates given a 20mg/kg intramuscular injection.
Elimination Route
Inositol is absorbed from the small intestine. In patients with inositol deficiency, the maximal plasma concentration after oral administration of inositol is registered to be of 4 hours. Inositol is taken up by the tissues via sodium-dependent inositol co-transporter which also mediates glucose uptake. Oral ingestion of inositol is registered to generate a maximal plasma concentration of 36-45 mcg.
10-33% of deuterium labelled vitamin E is absorbed in the small intestine. Absorption of Vitamin E is dependant upon absorption of the fat in which it is dissolved. For patients with poor fat absorption, a water soluble form of vitamin E may need to be substituted such as tocopheryl polyethylene glycol-1000 succinate.
In other studies the oral bioavailability of alpha-tocopherol was 36%, gamma-tocotrienol was 9%. The time to maximum concentration was 9.7 hours for alpha-tocopherol and 2.4 hours for gamma-tocotrienol.
Half Life
The pharmacokinetic profile of inositol was studied in preterm infants and the estimated elimination half-life was reported to be of 5.22 hours.
44 hours in premature neonates given a 20mg/kg intramuscular injection. 12 minutes in intravenous injection of intestinal lymph.
Clearance
The pharmacokinetic profile of inositol was studied in preterm infants and the estimated clearance rate was reported to be 0.0679 L.kg/h.
6.5mL/hr/kg in premature neonates given a 20mg/kg intramuscular injection.
Elimination Route
Most of the administered dose is excreted in urine.
Alpha tocopherol is excreted in urine as well as bile in the feces mainly as a carboxyethyl-hydrochroman (CEHC) metabolite, but it can be excreted in it's natural form .
Pregnancy & Breastfeeding use
Use in pregnancy: Vitamin E may be used in pregnancy in the normally recommended dose but the safety of high dose therapy has not been established.
Use in lactation: There appears to be no contraindication to breast feeding by mothers taking the normally recommended dose.
Contraindication
No known contraindications found.
Special Warning
Use in Children: Vitamin E is safe for children
Acute Overdose
Large doses of vitamin E (more than 1 gm/day) have been reported to increase bleeding tendency in vitamin K deficient patients such as those taking oral anticoagulants.
Storage Condition
