When purchasing vitamin E soft capsules, two common queries are: first, what are the differences between conventional vitamin E and natural vitamin E powder, and second, why is there such a significant price variation between various vitamin E products?
Differences Between Natural Vitamin E and Regular Vitamin E
◆Structural Differences: According to the Chinese Pharmacopoeia, natural vitamin E is (+)-2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-6-chromanol acetate or d-α-tocopheryl acetate. Synthetic vitamin E is (±)-2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-6-chromanol acetate or dl-α-tocopheryl acetate. Consequently, there are a few structural variations between the two.
◆Main Sources: Natural product is primarily derived from plant oils such as rapeseed oil, peanut oil, soybean oil, etc., while synthetic is mainly produced through chemical synthesis.
◆Absorption: Natural vitamin E has a higher rate of absorption than manufactured vitamin E and can enter the body directly through the small intestine. Before synthetic VE to be absorbed, it must first be hydrolyzed and converted in the digestive tract into vitamin E alcohol. Natural vitamin E has twice the bioavailability of synthetic vitamin E, according to research.
◆Biological Activity: Natural vitamin E has a 3–8 times higher biological activity than manufactured.
◆Duration of Action: Natural VE remains in the body for a longer period compared to synthetic vitamin E. According to clinical studies, the content of natural products in human plasma is 1.6 times greater than that of synthetic after 12 hours of oral ingestion. Three to four days later, the concentration of natural vitamin E is twice that of synthetic vitamin E.
Overall, it is thought that natural vitamin E powder is preferable to synthetic.
Price Variations Among Various Vitamin E Forms
First off, it should be noted that most vitamin E-containing health supplements cost more than pharmaceutical-grade versions of the vitamin. However, these prices are mainly influenced by market forces.
Second, due to its higher qualities, natural vitamin E typically costs more than synthetic vitamin E. For example, for vitamin E soft capsules with the same official pharmaceutical standard (usually indicated by a national drug approval number), the price of 100mg30 natural vitamin E may range from 10 to 20 yuan, while 100mg30 regular vitamin E may cost only a few yuan (usually not exceeding 5 yuan).
In conclusion, pharmaceutical-grade vitamin E is less expensive than vitamin E supplements, its prices can also change based on the product's requirements.
In theory, the pharmacological effects of natural vitamin E and regular vitamin E are the same. Therefore, the decision between the two might be based on personal preferences and financial factors. Let's now talk about the purposes and typical applications of vitamin E.
Applications of Vitamin E
1. Cardiovascular disease prevention and therapy: Vitamin E is an adjunctive treatment for cardiovascular disease due to its ability to raise high-density lipoprotein (HDL), lower cholesterol, prevent the development of atherosclerosis, and protect the heart muscles from oxidative damage.
2. Preconception Care for Women: Vitamin E can increase the secretion of gonadotropins, promote follicle growth, and enhance the effects of progesterone. It is used to treat infertility as well as frequent miscarriages and impending miscarriages.
3. Preconception Care for Men: Vitamin E can improve sperm concentration, motility, and the percentage of normal sperm, thus increasing the chances of natural conception.
Skin Conditions and Hyperpigmentation: Vitamin E contains antioxidant characteristics that aid in reducing pigment deposition, maintaining smooth and moisturized skin, increasing skin suppleness, and delaying the aging process of the skin.
4. Wound Healing and Scar Management: Vitamin E can reduce scar formation by inhibiting excessive collagen deposition at wound sites.
5. Vaginal Health in Elderly Women: Oral vitamin E can raise estrogen levels, protect the cell membranes of normal vaginal cells, enhance the immune response of normal vaginal microbiota, and promote recovery in cases of elderly vaginal inflammation.
