How Does Vitamin A Prevent Acne Outbreaks?For over four decades, vitamin A has gained medical attention for its anti-acne traits. Because of this vitamin's versatility and efficacy at treating acne, there are now over three generations of vitamin A derived medicines used to combat acne. So whThe varied functions of vitamin A The nutrient vitamin A serves a key role in vision, bone growth, reproduction, cell division, and cell differentiation. In addition, vitamin A enhances immune strength by helping produce white blood cells that attack bacteria and viruses. Vitamin A and acne control According to an investigation in Cutis, vitamin A can control or modify the steps involved in creating acne lesions. One of those steps involves improper shedding of skin cells. Vitamin A can improve how the pores remove dead skin cells and this lowers the chances of developing clogged pores that provoke surplus growth of the acne activating bacteria Propionibactium acnes. Moreover, a report in the Proceedings of the Nutrition Society have found that a vitamin A deficiency can induce inflammation and escalate existing inflammatory states. Clinical research Based on these findings, investigators concluded that low vitamin A blood levels could cause or worsen an acne outbreak. Years earlier, an investigation in the British Journal of Dermatology found that low vitamin A blood levels corresponded to heightened levels of severe, cystic acne in male volunteers. How much Vitamin A to take The daily value for vitamin A for an adults is 5,000 IU (international units). The recommended dietary allowance for vitamin A is 900 miligrams per day or 3,000 IU per day. The tolerable upper level of vitamin A for adults is 10,000 IU each day. Excess dosages of vitamin A can cause liver toxicity, birth defects and/or nausea. Where to get vitamin A Vitamin A found in animal-based foods is called "preformed" vitamin A. Animal-based vitamin A is absorbed in the form of retinol. The body can then convert this retinol into other active forms of vitamin A like retinal and retinoic acid. Food sources of vitamin A include beef liver, chicken liver, fortified milk, cheese and eggs. According to the Mayo Clinic, the best source of needed nutrients is a balanced diet. However, for individuals whose health conditions, lifestyle choices or medications hamper their bodies' ability to receive or absorb proper amounts of vitamin A from foods, a supplement is in order. In short, clinical research has definitely recognized vitamin A as an acne preventative. Thus, adequate consumption of vitamin A should be considered a integral part of treating acne.
