Erich Uses, Dosage, Side Effects, Food Interaction and all others data.
Erich exists in four different forms designated as α, β, δ, and γ. They present strong antioxidant activities, and it is determined as the major form of vitamin E. Erich, as a group, is composed of soluble phenolic compounds that consist of a chromanol ring and a 16-carbon phytyl chain. The classification of the tocopherol molecules is designated depending on the number and position of the methyl substituent in the chromanol ring. The different types of tocopherol can be presented trimethylated, dimethylated or methylated in the positions 5-, 7- and 8-. When the carbons at position 5- and 7- are not methylated, they can function as electrophilic centers that can trap reactive oxygen and nitrogen species. Erichs can be found in the diet as part of vegetable oil such as corn, soybean, sesame, and cottonseed. It is currently under the list of substances generally recognized as safe (GRAS) in the FDA for the use of human consumption.
The antioxidant effects of tocopherol can be translated into different changes at the pharmacodynamic level. In vitro studies have shown that this antioxidant activity can produce modification in protein kinase C (PKC) which will later be translated into an inhibition of cell death. Some other derivate effects are the anti-inflammatory properties of tocopherol which can be related to the modulation of cytokines or prostaglandins, prostanoids and thromboxanes.

Uses
Erich can be used as a dietary supplement for patients with a deficit of vitamin E; this is mainly prescribed in the alpha form. Vitamin E deficiency is rare, and it is primarily found in premature babies of very low birth weight, patients with fat malabsorption or patients with abetalipoproteinemia.
Erich, due to its antioxidant properties, is studied for its use in prevention or treatment in different complex diseases such as cancer, atherosclerosis, cardiovascular diseases, and age-related macular degeneration.
Erich is also used to associated treatment for these conditions: Vitamin E Deficiency, Skin Care
How Erich works
Erich acts as a radical scavenger. It mainly acts as an antioxidant for lipid bilayers. Erich's functions depend on the H-atom donating ability, location, and movement within the membrane, as well as the efficiency in the radical recycling by some cytosolic reductants such as ascorbate. Erich actions are related to the trap of radicals, and it has been shown that even in the absence of substituents in the ortho-positions, tocopherol can trap more than two radicals. The type of radicals available for tocopherol are alkyl and peroxy.
Toxicity
Erichs are considered as non-toxic but if very high doses are administered, there are reports of hemorrhagic activity. Reproductive and developmental toxicity tests are negative. These negative results were also observed in the analysis of mutagenicity and carcinogenicity.
Food Interaction
No interactions found.Volume of Distribution
The apparent volume of distribution of tocopherol is approximately 0.5 ml.
Elimination Route
The absorption of tocopherol in the digestive tract requires the presence of fat. The approximate tmax of the four different isomers of tocopherol is attained in the range of 3-6 hours. When compared with tocotrienols, tocopherols showed a reduced bioavailability. The bioavailability of tocopherols is highly dependent on the type of isomer that is administered where the alpha-tocopherol can present a bioavailability of 36%. This isomer specificity also determines the intestinal permeability in which the gamma-tocopherol presents a very low permeability. After oral administration, the Cmax, AUC and mean residence time of tocopherols showed to be dependent on the isomer and ranged from 590-2915 ng/ml, 3740-10169 ng/ml and 4.85-5.74 h, respectively.
Half Life
The elimination half-life of tocopherol is approximately 2.6 hours.
Clearance
The clearance rate of tocopherol is approximately 0.15 l/h.
Elimination Route
The pharmacokinetic profile of tocopherol indicates a longer time of excretion for tocopherols when compared to tocotrienols. The different conjugated metabolites are excreted in the urine or feces depending on the length of their side-chain. Due to their polarity, intermediate-chain metabolites and short-chain metabolites are excreted via urine as glucoside conjugates. A mixture of all the metabolites and precursors can be found in feces. The long-chain metabolites correspond to >60% of the total metabolites in feces. It is estimated that the fecal excretion accounts for even 80% of the administered dose.
