Vitamin E is a fat-soluble vitamin that can be found naturally in some foods, added to others, or taken as a dietary supplement. The term “vitamin E” refers to a group of fat-soluble molecules with different antioxidant properties.
Vitamin E is found in eight different chemical forms in nature (alpha-, beta-, gamma-, and delta-tocopherol, and alpha-, beta-, gamma-, and delta-tocotrienol), each with a different level of biological activity. The only type of tocopherol acknowledged to suit human needs is alpha- (or -) tocopherol.
Vitamin E (alpha-tocopherol) serum concentrations are determined by the liver, which absorbs the nutrient after the various forms are absorbed from the small intestine. Only alpha-tocopherol is resecreted by the liver via the hepatic alpha-tocopherol transfer protein.
marriage potentially stop a girl’s formal education (Noor & Mohd, 2018, p.15). When a girl gets married, she is often told to drop out of school. Girls tend to drop out of college during the preparatory time before or after the marriage. Her new role as a wife or mother frequently comes with the expectation that she will take care of the home, the young people and the prolonged family. It is also said that when a girl is out from the school, she becomes more vulnerable. Many females are not in school because it is inaccessible and expensive, and also due to the fact it is viewed as something that irrelevant to their lives. With few alternatives, mothers and fathers often see marriage as a nice choice for their daughter. Moreover, girls who have dropped out of school are likely will get married at the age of 18 compared to ladies with secondary or higher education. Returning to school can be difficult for married girls; this is the reality for them. Girls who marry young are no longer capable to resume their education because the community could not accept their situation. For instance, the stigma of pregnancy keeps girls from returning to school. Some nations also forbid pregnant girls and younger moms from returning to school. Education is a powerful strategy to end child marriage. Education can be one of the most effective equipment to enable girls to keep away from child marriage and fulfill their potential. The longer a girl stays in school, the less probable she is to be married before the age of 18 and have adolescents throughout her teenage years. When females have gotten entry to safe, satisfactory secondary education, the benefits are widely felt. Educated females improve skills, understanding and confidence to make informed choices together with if, when and whom to marry. Being in school additionally helps the perception that women are nevertheless teens and are consequently not of an appropriate age to marry.
Despite the fact that child marriages are a big concern for the community, some of the families in the country who are in favour of child marriage argued that marrying off one’s child can be their escapade from poverty, especially in poverty-stricken areas (Brown, 2018, p.10). Indeed, child marriages may allow families to reduce their general expenses. Admittedly, these families have fewer options because of not enough opportunities and resources so through marrying their child off to another family, they will have one person less to feed, clothe and educate. Additionally, parents and families were also offered economic incenti
