It is naturally produced in the body through exposure to sunlight and can also be obtained through certain foods and supplementation
Studies finding protective effects against cancer: A meta-analysis found that two copies of the C677T variant (AA genotype) decrease the risk of colon cancer by about 20%![ref] Another meta-analysis found that two copies of the C677T variant (AA genotype) were protective against prostate cancer .[ref] The MTHFR C677T variant decreases the relative risk of retinoblastoma and oral squamous cell cancer.[ref][ref] Two copies of the C677T variant (AA genotype) are protective against gastric cancer.[ref] However, for someone who has cancer, the MTHFR C677T variant is associated with poorer outcomes.[ref] The MTHFR A1298C variant (GG or GT) is associated with a decreased risk of hypothyroidism .[ref] The flip side: Folate can also help protect against cancerous mutations in the first place

Purser drill down into the genetic errors of two children and discuss their potential inflammation, immune system functionality (or lack thereof), risk for autism, how to vaccinate, therapy options, and stressors
These redox PTMs sometimes affect cysteines that are strictly conserved, at least in the photosynthetic organisms analyzed here, suggesting that the mechanism may be conserved and physiologically relevant in a wide range of species
First, this study was unable to elucidate the underlying mechanism causing the poor prognosis in patients with GPX4 positive NSCLC
Nutritional deficiencies in vitamin C, K, or iron also impair blood vessel integrity and healing speed
