    Secondary research titled: Critical review: “Vitamin D supplementation on plasma calcidiol levels and survival in patients with colorectal cancer.” We aimed to identify the effect that vitamin D supplementation has on plasma calcidiol levels and survival in patients with colorectal cancer. The clinical question was: Does vitamin D supplementation increase plasma vitamin D levels and improve survival rate in patients with colorectal cancer? The Evidence-Based Nutrition methodology was used. The information search was carried out in Science Direct, Pubmed, Splingerlink, Lilacs, Latindex and Scielo, finding 60 articles, 15 being selected that have undergone exhaustive selection with the CASPE tool such as “the effect of vitamin D supplementation on survival in patients with “colorectal cancer: systematic review and meta-analysis of randomized controlled trials.” which met the expectations of the objectives proposed herein, and also obtained a STRONG recommendation grade and A1 level of evidence. Vitamin D supplementation at doses of 2000 IU to 4000 IU showed improvements in plasma calcidiol levels and overall survival and relapse-free survival rates in patients with colorectal cancer.
