Often used as a marketing buzzword, learn about the role of antioxidants beyond the hype, and some of the research on health and disease prevention. Jump to: – – – – – The body’s trillion or so cells face formidable threats, from lack of food to infection with a virus. Another constant threat comes from chemicals called free radicals. In very high levels, they are capable of damaging cells and genetic material. The body generates free radicals as the inevitable byproducts of turning food into energy. Free radicals are also formed after exercising or exposure to cigarette smoke, air pollution, and sunlight. [1] Free radicals come in many shapes, sizes, and chemical configurations. What they all share is a voracious appetite for electrons, stealing them from any nearby substances that will yield them. This electron theft can radically alter the “loser’s” structure or function. Free radical damage can change the instructions coded in a strand of DNA. It can make a circulating low-density lipoprotein (LDL, sometimes called bad cholesterol) molecule more likely to get trapped in an artery wall. Or it can alter a cell’s membrane, changing the flow of what enters the cell and what leaves it. An excessive chronic amount of free radicals in the body causes a condition called oxidative stress, which may damage cells and lead to chronic diseases. [2] We aren’t defenseless against free radicals. The body, long used to this relentless attack, makes many molecules that quench free radic...

Preservatives are commonly used as additives in pharmaceutical products, food and cosmetics. Some of the liquid preparation are susceptible to microbial contamination because of the nature of ingredients present in it. Such preparation are protected by preservatives which avoids degradation and alteration of the product.A preservative is a natural or synthetic chemical added to various products which helps to prevent microbial decomposition. Present article deals with the study of ideal properties, classification, mechanism of action, Pharmaceutical applications and its impact on health of various preservatives used in pharmaceuticals.

Antioxidant supplements are popular and commonly considered healthy. In part, this is because fruits and vegetables, which are rich in antioxidants, are associated with many health benefits, including a reduced risk of disease ( Yet, there is strong evidence to suggest that you may be doing your health a disservice by supplementing with antioxidants. This article explains what antioxidant supplements are and why it’s better to get your antioxidants from food. Antioxidant supplements contain concentrated forms of antioxidants, which are substances that stabilize free radicals. Your body naturally produces free radicals when you exercise and digest food. Environmental factors, such as UV exposure, air pollutants, tobacco smoke and industrial chemicals like If free radicals exceed your body’s ability to regulate them, a condition called oxidative stress occurs. Over time, this contributes to aging and the development of diseases, including cancer ( The main antioxidants that help regulate free radicals in your body are the vitamins A, C, and E and the mineral selenium. Antioxidant supplements contain 70–1,660% of the daily value (DV) of these key nutrients ( It’s commonly thought that taking antioxidant supplements prevents the damage caused by free radicals to the body’s cells, thereby promoting longevity and warding off disease. However, taking antioxidant supplements in high amounts can do just the opposite. Summary Antioxidant supplements contain concentrated forms of ant...
