Vitamin C in Lyme disease

Vitamin C's antimicrobial, bactericidal, antiviral, antiparasitic, and antifungal effect is based on various molecular mechanisms, mainly its antioxidant and immunomodulatory potential. All of these make it highly effective for supportive treatments for Lyme disease. The 10- to 100-fold higher concentration of vitamin C in leukocytes relative to plasma is the best evidence of the crucial role vitamin C plays in a host of immune cell functions, such as proliferation and differentiation, beyond its potent anti-inflammatory effect.

Thus, vitamin C plays an essential regulatory role in the functioning of monocytes and macrophages, the innate immune system's first line of defense against invading pathogens. Vitamin C protects neutrophils against oxidative stress, improving cell motility in response to chemotactic stimuli. It also plays a vital role in the proliferation and function of B, T, and NK immune lymphocytes, so crucial in the fight against Lyme disease.

Vitamin C in Lyme disease

Since the late 1930s, vitamin C has proven effective in fighting bacterial infections. Studies have demonstrated its antimicrobial effects against bacteria such as Mycobacterium tuberculosis, the hemolytic streptococcus A group, Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Helicobacter pylori, Salmonella enterica, and Campylobacter jejuni,

Vitamin C has also proven effective in treating infections with gram-positive bacteria such as S. aureus and S. epidermidis, or gram-negative bacteria such as Klebsiella pneumoniae and Proteus mirabilis, in synergy with epigallocatechin gallate or quercetin.

The antimicrobial effects of vitamin C aren't limited to bacteria. Its immunomodulatory action has also proven effective against parasites, fungi such as candida, and especially viruses such as herpes simplex poliovirus and influenza.
