Anthocyanin-Rich Berry Supplementation in Patients With Colorectal Cancer

This prospective, open-label interventional study evaluated the effects of short-term supplementation with an anthocyanin-rich freeze-dried black raspberry and strawberry preparation in patients undergoing treatment for colorectal cancer. The study assessed the tolerability of the intervention and longitudinal changes in nutritional status and selected inflammatory and biochemical biomarkers. Participants received the anthocyanin-rich supplement for 21 consecutive days in addition to standard oncological treatment and were assessed at baseline and during follow-up.
