Unlike other mammals, with the exception of guinea pigs, primates, including we humans, do not synthesize vitamin C in the liver. A mutation in the gulonolactone oxidase (GULO) gene means that we must rely solely on dietary intake; otherwise, we\u2019ll develop scurvy, among other health issues.<\/p>\n<p>Eating vitamin C-rich foods is always preferable because whole plant foods contain lots of other beneficial phytonutrients, not just vitamin C. If fruits and vegetables are not available, vitamin C-fortified foods are second best; supplements may be necessary in the situation of advanced health need, or the presence of a genetic variant (GSTT1) in which the body cannot process dietary vitamin C effectively. Even in the United States where the availability of citrus fruits and other vitamin C-rich foods is relatively widespread, vitamin C deficiency is the fourth most common nutrient deficiency.<a href=\"#_edn1\" name=\"_ednref1\">[i]<\/a><\/p>\n<p><strong><br \/>\nVitamin C-rich Foods<\/strong><\/p>\n<ul>\n<li>Black currants<\/li>\n<li>Red peppers<\/li>\n<li>Kiwifruit<\/li>\n<li>Guavas<\/li>\n<li>Green bell peppers<\/li>\n<li>Oranges<\/li>\n<li>Strawberries<\/li>\n<li>Papayas<\/li>\n<li>Pineapples<\/li>\n<li>Lemons<\/li>\n<li>Grapefruit<\/li>\n<\/ul>\n<p><strong>Supporting the Immune System<br \/>\n<\/strong>In people who are otherwise healthy, their immune systems are capable of handling oxidative stress and otherwise support the body\u2019s healing processes and immune system. Optimizing your immune system\u2019s ability to perform its designated functions is a great reason to make sure you\u2019re getting sufficient vitamin C in your diet. Here are three key functions that vitamin C performs within the human body:<\/p>\n<ul>\n<li>Promotes the proliferation of immune cells (T-cells, B-cells)<\/li>\n<li>Neutralizes free radicals (reactive oxygen species)<\/li>\n<li>Contributes to collagen production in skin cells<\/li>\n<\/ul>\n<p><strong>Vitamin C Deficiency\/Insufficiency<\/strong><br \/>\nResearch suggests that prolonged vitamin C insufficiency leads to impaired immune function, resulting in a myriad of negative health conditions and outcomes <a href=\"#_edn2\" name=\"_ednref2\">[ii]<\/a>,<a href=\"#_edn3\" name=\"_ednref3\">[iii]<\/a> Proponents of vitamin C supplementation encourage its prophylactic use to reduce oxidative stress and thus, fend off any compromise in immune function. Vitamin C supplementation for situational use is also recommended.<\/p>\n<p><strong><br \/>\nVitamin C Requirements<\/strong><br \/>\nBecause vitamin C is a water-soluble vitamin, whatever the body doesn\u2019t need will be excreted in the urine. In other words, the body does not readily store vitamin C \u2013 whether it comes from foods or a supplement, so regular, daily consumption is ideal. Consuming too much vitamin C all at once can irritate the stomach and cause irritation (vitamin C is acidic). You should spread your intake of vitamin C throughout the day, especially if you decide to take upwards of 2000mg\/day. The current RDA is 75mg for healthy women and 90mg for healthy men.<a href=\"#_edn4\" name=\"_ednref4\">[iv]<\/a> Smokers need an additional 35mg to combat the oxidative stress due to smoking.<\/p>\n<p><strong><br \/>\nOptimizing a Supplement<\/strong><br \/>\nTraditional vitamin C supplements and multivitamins with vitamin C have low bioavailability. If you consume a large quantity to make up for the low bioavailability, you\u2019re likely to experience extreme stomach discomfort. Some vitamin C-rich foods have similar drawbacks. Another spoke in the wheel is due to the transit through the G.I. tract. As the vitamin C comes in contact with enzymes, digestive juices, and bile salts that essentially \u201cuse up\u201d most of the antioxidant capacity. This makes a liposomal vitamin C supplement more desirable. Liposome encapsulated vitamin C reaches all the way to the liver non-oxidized (not \u201cused up\u201d) and is 10-20 times more bioavailable than non-encapsulated vitamin C.<a href=\"#_edn5\" name=\"_ednref5\">[v]<\/a> A liposomal form may be a little more expensive, but provides the anticipated health benefits and stomach upset is not a problem.<\/p>\n<p>______________________________________________________________________________________________________________________________<\/p>\n<p><a href=\"#_ednref1\" name=\"_edn1\">[i]<\/a> Carr AC, Maggini S.

After spending a considerable amount of time doing \u201call the right things\u201d without seeing any results, she decided to seek out the root cause of her health problems. Samantha was no stranger to the natural abilities of the human body. As a young athlete, Samantha first set goals for herself in team sports such as synchronized swimming, water polo, and field hockey. In high school, she focused on rowing, where she was a member of the St. Louis Rowing Club &amp; one of a team of eight young women who were ranked nationally. Samantha\u2019s perseverance to improve her health and her athletic ability created a career path as a Functional Diagnostics Practitioner. After receiving her B.A. in Sports Management &amp; Functional Movement from the University of Michigan in 2003, she decided to open her own holistic practice, See Fit. Today, she works with clients to identify the root cause instead of a \u201cband-aid\" approach. Using an individualized, holistic path, she incorporates lifestyle, diet, rest, exercise, stress reduction, and supplementation to help her clients achieve their ultimate health and wellness goals regardless of their current age, gender, and ability.","sameAs":["https:\/\/sovereignlaboratories.com"]}]}},"_links":{"self":[{"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/posts\/1770","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/users\/12"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/comments?post=1770"}],"version-history":[{"count":3,"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/posts\/1770\/revisions"}],"predecessor-version":[{"id":2018,"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/posts\/1770\/revisions\/2018"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/media\/1772"}],"wp:attachment":[{"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/media?parent=1770"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/categories?post=1770"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sovereignlaboratories.com\/blog\/wp-json\/wp\/v2\/tags?post=1770"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
