RESUMO

Chemotherapy represents the main pharmacological cancer treatment. Recently, positive effects emerged with the combination of anticancer therapy and nutraceutical products. The aim of this systematic review is to collect and synthesize the available scientific evidence regarding the potential effects of nutraceuticals on cancer cells. A systematic literature search of randomized clinical trials of nutraceutical products in patients with cancer published up to 15 December 2022 was conducted using three data sources: Embase, PubMed, and Web of Science. The effect of high-dose isoflavone supplements on prostate cancer resulted in stabilization or reduction of PSA concentrations in 50% of isoflavone group patients six months after treatment. High doses of vitamin D supplementation plus chemotherapy in patients with advanced or metastatic colorectal cancer showed a median PFS of 13.0 months (95% CI, 10.1-14.7 months) for 49 patients. The effect of vitamin D supplementation on markers of inflammatory level and antioxidant capacity in women with breast cancer showed a significant increase in serum vitamin D concentration (28 ± 2.6 to 39 ± 3.5; p = 0.004) after 8 weeks of treatment. In conclusion, nutraceutical supplements represent a potentially growing sector and can be utilized in medical treatment or nutrition to provide integrated medical care.

RESUMO

Rising rates of obesity has increased the global use of herbal supplements intended to control weight. However, taking these preparations without appropriate medical supervision could increase the risk of manifestation of side effects, especially at the hepatic level. In literature, different cases of acute liver injury consequent to the use of food supplements containing Garcinia cambogia and hydroxycitric acid are reported. This letter aims to review the most recent literature that analysed the herb-induced liver disease due to the use of hydroxycitric acid, from the first alert coming from the European Food and Drug Administration in 2009, to the last recent European food alerts from 2020 to 2021. It is noteworthy that in some cases it demonstrated the relationship between hydroxycitric acid and hepatotoxicity. Therefore, there is a need to draw more attention to the relationship between a safe use and a more awareness in the intake of these supplements, to preserve the safety of the consumers who increasingly purchase food supplements, products that have only nutritive properties and are never curative.
