Carr AC, Maggini S. Vitamin C and Immune Function. Nutrients. 2017 Nov 3;9(11):1211. doi: 10.3390/nu9111211.

Abstract. Vitamin C is an essential micronutrient for humans, with pleiotropic functions related to its ability to donate electrons. It is a potent antioxidant and a cofactor for a family of biosynthetic and gene regulatory enzymes. Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune system.

Bucher A, White N. Vitamin C in the Prevention and Treatment of the Common Cold. Am J Lifestyle Med. 2016 Feb 9;10(3):181-183. doi: 10.1177/1559827616629092.

Abstract. The purpose of this article is to review the current data on the relationship between vitamin C and immune function, specifically, the utility of vitamin C supplementation in the prevention and treatment of the common cold.

Linowiecka K, Foksinski M, Brożyna AA. Vitamin C Transporters and Their Implications in Carcinogenesis. Nutrients. 2020 Dec 18;12(12):3869. doi: 10.3390/nu12123869.

Abstract. This review discusses the potential effects of vitamin C and the impaired SVCT function in cancers. The variations in vitamin C transporter genes may regulate the active transport of vitamin C, and therefore have an impact on cancer risk, but further studies are needed to thoroughly elucidate their involvement in cancer biology.

Hemilä H. Vitamin C and Infections. Nutrients. 2017 Mar 29;9(4):339. doi: 10.3390/nu9040339.

Abstract. In the early literature, vitamin C deficiency was associated with pneumonia. After its identification, a number of studies investigated the effects of vitamin C on diverse infections. 

Marik PE. Vitamin C for the treatment of sepsis: The scientific rationale. Pharmacol Ther. 2018 Sep;189:63-70. doi: 10.1016/j.pharmthera.2018.04.007.

Abstract. Sepsis is associated with an acute deficiency of vitamin C. In experimental sepsis models, intravenous vitamin C reduces organ injury and improves survival. In addition, emerging evidence suggests that the combination of vitamin C, corticosteroids and thiamine may act synergistically to reverse sepsis induced organ dysfunction. 

Wang K, Jiang H, Li W, Qiang M, Dong T, Li H. Role of Vitamin C in Skin Diseases. Front Physiol. 2018 Jul 4;9:819. doi: 10.3389/fphys.2018.00819. 

Abstract. In this review, we will summarize the effects of vitamin C on four skin diseases (porphyria cutanea tarda, atopic dermatitis, malignant melanoma, and herpes zoster and postherpetic neuralgia) and highlight the potential of vitamin C as a therapeutic strategy to treat these diseases, emphasizing the clinical application of vitamin C as an adjuvant for drugs or physical therapy in other skin diseases.

Tada A, Miura H. The Relationship between Vitamin C and Periodontal Diseases: A Systematic Review. Int J Environ Res Public Health. 2019 Jul 11;16(14):2472. doi: 10.3390/ijerph16142472. 

Abstract. Vitamin C is important for preventing and slowing the progression of many diseases. There is significant evidence linking periodontal disease and vitamin C. We aimed to systematically review the studies addressing the relationship between vitamin C and periodontal disease, and the preventive ability of vitamin C against periodontal disease. 

Carr AC, McCall C. The role of vitamin C in the treatment of pain: new insights. J Transl Med. 2017 Apr 14;15(1):77. doi: 10.1186/s12967-017-1179-7. 

Abstract. Herein we propose a novel analgesic mechanism for vitamin C; as a cofactor for the biosynthesis of amidated opioid peptides. It is well established that vitamin C participates in the amidation of peptides, through acting as a cofactor for peptidyl-glycine α-amidating monooxygenase, the only enzyme known to amidate the carboxy terminal residue of neuropeptides and peptide hormones.

Van der Velden U. Vitamin C and Its Role in Periodontal Diseases - The Past and the Present: A Narrative Review. Oral Health Prev Dent. 2020;18(1):115-124. doi: 10.3290/j.ohpd.a44306.

Abstract. In humans, ascorbic acid, better known as vitamin C, is a true vitamin because humans lack the ability to synthesise it. Vitamin C exhibits a number of enzymatic and non-enzymatic effects but all are accounted for by the ability of vitamin C to donate electrons and therefore acts as a reducing agent. It has a wide range of functions. 

 Plevin D, Galletly C. The neuropsychiatric effects of vitamin C deficiency: a systematic review. BMC Psychiatry. 2020 Jun 18;20(1):315. doi: 10.1186/s12888-020-02730-w. 

Abstract. Vitamin C deficiency may be more common than is generally assumed, and the association between vitamin C deficiency and adverse psychiatric effects has been known for centuries. This paper aims to systematically review the evidence base for the neuropsychiatric effects of vitamin C deficiency.
