| Vitamin D3 (Cholecalciferol) - Major VITAL study stated Vit D did not reduce invasive cancer, but Secondary Analysis stated reduces the incidence of metastatic cancer at diagnosis. - Amount needed may depend on your BMI. - Vitamin D deficiency, as determined by serum 25(OH)D concentrations of less than 30 ng/mL, - Target achieving 80 ng/mL - Vitamin D may modulate oxidative stress markers. (ROS) - Nrf2 plays a key role in protecting cells against oxidative stress; this is modulated by vitamin D - Vitamin D has antioxidant and anti-inflammatory regulatory effects; whether supplementation alters response to specific chemotherapy regimens remains context-dependent and not firmly established. - excess Vit D can raise calcium and cause harm Vitamin D deficiency is generally defined as serum 25(OH)D <20 ng/mL (50 nmol/L), though some guidelines consider ≥30 ng/mL sufficient. - One recommendation is to get your level up to around 125 ng/ml (however not supported by consensus clinical trial evidence). - Chemo depletes Vitamin D levels so 10,000 IUs daily? – ask your doctor first. Typical maintenance dosing for most adults is 800–2000 IU/day; higher doses may be used short-term under medical supervision when correcting deficiency. After correction of vitamin D deficiency through loading doses of oral vitamin D (or safe sun exposure), adequate maintenance doses of vitamin D3 are needed. This can be achieved in approximately 90% of the adult population with vitamin D supplementation between 1000 to 4000 IU/day, 10,000 IU twice a week, or 50,000 IU twice a month [10,125]. On a population basis, such doses would allow approximately 97% of people to maintain their serum 25(OH)D concentrations above 30 ng/mL [19,126]. Others, such as persons with obesity, those with gastrointestinal disorders, and during pregnancy and lactation, are likely to require doses of 6,000 IU/day. Vitamin D, particularly its active form 1,25-dihydroxyvitamin D (calcitriol), exerts multiple biological effects that may influence cancer development and progression. Calcitriol has been reported to induce cell cycle arrest (often at the G0/G1 phase) and promote pro-apoptotic mechanisms in various cancer cell types. Inhibition of Angiogenesis: Some studies indicate that vitamin D can reduce the expression of pro-angiogenic factors, thereby potentially limiting the blood supply to tumors, which is necessary for tumor growth and metastasis. Effects on the Wnt/β-catenin Pathway: The Wnt/β-catenin signaling pathway, often dysregulated in several cancers (for example, colorectal cancer), may be modulated by vitamin D. Calcitriol has been shown in some models to inhibit β-catenin signaling, which is associated with decreased cell proliferation and tumor progression. Vitamin D may interact with other signaling pathways, including the PI3K/AKT/mTOR pathway, which is involved in cell survival and proliferation.
Time-Scale Flag (TSF): P / R / G
Clinical trial data suggest vitamin D supplementation effects may be attenuated in individuals with obesity, potentially due to pharmacokinetic and inflammatory differences.

| Also known as SLC2A1 An important hallmark in cancer cells is the increase in glucose uptake. GLUT1 is an important target in cancer treatment because cancer cells upregulate GLUT1, a membrane protein that facilitates the basal uptake of glucose in most cell types, to ensure the flux of sugar into metabolic pathways. GLUT1 is a member of the facilitated glucose transporter family and is widely expressed in various tissues, including red blood cells, brain, and cancer cells. GLUT1 has been shown to be overexpressed in many types of tumors, including breast, lung, and colon cancer. This overexpression may contribute to the development and progression of cancer by promoting glucose uptake and energy production in cancer cells. GLUT1 is a protein that facilitates the transport of glucose across cell membranes. GLUT1 plays a role in the regulation of glucose metabolism in diabetes. GLUT1 plays a role in the regulation of glucose metabolism in diabetes. GLUT1 is also known to be involved in the Warburg effect. GLUTs are expressed 10–12-fold higher in cancer cells than in healthy tissues, especially in highly proliferative and malignant tumors. Downregulators: -Resveratrol: associated with reduced GLUT1 expression. -Curcumin: downregulate GLUT1 in various cancer cell lines -Quercetin: downregulating the expression and function of GLUT1. -EGCG: suppress GLUT1 expression -Berberine: linked to decreased expression or activity of GLUT1. |
