Nutrition-VitaminDeficiency and Supplements

Feliciashould contact her doctor to get more information before taking therecommended supplement by her friend. It is important for a patientto authenticate the supplement’s effectiveness in publishedscientific studies (NIH Clinical Center, 2011). Vitamins and mineralsnaturally are contained in the foods we take in amounts that the bodycan easily handle. National Health Services (2015), many vitamins arewater soluble and thus when taken in excess amounts are automaticallyflushed out through the urine. However, vitamins A, D, E and K aresoluble in fats and hence stored in the body. Overconsumption ofvitamin can result in complications because they cannot be excretednaturally. Therefore, Felicia should evaluate the recommendedsupplement by assessing its contents to ensure that fat solublevitamins are in recommended amounts.

IfFelicia takes the recommended dose of two caplets per day, she islikely to encounter some problems. Daily consumption of thesupplement, will lead to vitamin a toxicity since the supplementcontains 5000IU, a very high amount in a single dose.According to NIH Clinical Center (2011), a supplement that providesvitamin A in beta-carotene is effective since beta-carotene is thesafest form of the vitamin. Some complications that Felicia maydevelop is an itchy skin, nausea and loss of appetite. If shecontinues to overuse the vitamin for a long time, she might developmore serious health conditions such as blurred vision. The supplementcontains a high amount of vitamin D and hence if taken consistentlyevery day can lead to toxicity. According to National Health Services(2015), overuse of vitamin D can result in loss of appetite, vomitingand slowed mental growth.

Itis clear that Fred might be lacking vitamin B12 and D. According toMorris (2012), lack of vitamin B12 is linked to Dementia and memoryloss. Vitamin B12 is necessary for a healthy brain since it protectsthe brain from diseases that affect it such as cardiovascular andhigh blood pressure. Besides vitamin B12 deficiency, Fred might belacking adequate vitamin D. According to Dunkin (2014), vitamin Ddeficiency is associated with cognitive problems since it isessential for enhancing brain operations such as coordination. Fred’smay have developed this condition despite the fact that his eatinghabits have not changed.

SinceFred claims to be eating healthy, he might be taking a diet that doesnot contain the recommended amounts of vitamin B12 and D. Fred mightbe taking more of a vegan diet to keep fit and hence consuming few ifany animal products such as fish, cheese, fortified milk and beefliver. Vitamin D and B12 are mainly found in animal products (Dunkin,2014: Morris, 2012) and since Fred is taking a strict diet to keephealthy, he might be consuming very low amounts of animal productshence getting inadequate vitamins. However, Fred can change his dietto reverse the deficiency. According to Morris, to reverse VitaminB12 deficiency, a person should regulate the diet to incorporate moreanimal products such as fish and its products (2012). If thedeficiency is severe, Fred should take vitamin B12 supplements butshould first consult his doctor for advice on the best supplement touse. Dunkin explains that vitamin D deficiency can be reversed byconsuming animal products such as milk, cheese (2014). Increasedexposure to sunlight can also be a good source of vitamin D. Fred canalso take Vitamin D supplements with the help of his doctor.
