Does chicken extract supplementation improve mood, cognition, and heart rate variability in healthy young adults?
Ten days of chicken extract supplementation may improve mood and alter heart rate variability in healthy young adults.
May suggest mood benefits from chicken extract in young adults; leaves open causal effects on HRV, cognition, and cortisol pending RCTs.
Chicken extract, which is rich in anserine and carnosine, has been widely taken in Asian countries as a traditional remedy with various aims, including attenuation of psychological fatigue. The effects of consuming BRAND'S Essence of Chicken (EOC) or a placebo on 46 young adults' responses to a standard psychological "stressor" were considered. Heart rate variability (HRV), cortisol responses, mood and cognition were measured at baseline and after ten days supplementation. EOC resulted in feeling less anxious, depressed and confused and more agreeable and clearheaded. A decrease in HRV was observed after EOC but only in females. Cognition and cortisol levels were not influenced by EOC. Findings suggest that EOC may be a promising supplement to improve mood in a healthy population.
