About the amino acid results
- Original report unit
- 1 ppm = 1 mg/kg. These are not per-pouch values.
- Total of 18 items
- 54,702 mg/kg (= 5,470.2 mg/100 g), calculated from the 18 reported values rather than tested separately by SGS.
- BCAA three-item total
- Isoleucine 948 + leucine 1,943 + valine 1,343 = 4,234 mg/kg (= 423.4 mg/100 g), not a separate SGS test item.
- Hydrolyzed amino acid profile
- The SGS hydrolyzed-amino-acid test and FIRDI free-amino-acid test use different methods, so their values should not be compared directly.
Alanine through valine (17 items): SGS SOP TESP-VC-0040, referring to AOAC 994.12. Tryptophan: SGS SOP TESP-VC-0087, referring to AOAC 988.15.

Ingredient Research and Reading Guide
Three selected papers introduce the overall evidence, ingredient background, and human research findings and limitations.
These studies did not test Chengyun Silkie Chicken Essence. Formulations, doses, and participants differ; their findings cannot establish the same effects for this product.
Chicken essence and cognition: an evidence overview
Research topic: A systematic review and meta-analysis of chicken essence and cognitive function.
Summary — Some executive-function analyses were positive, but limited study quality and inconsistent findings leave insufficient convincing evidence to establish cognitive benefits.
Nutrients, 8(1):57. DOI: 10.3390/nu8010057
Read the paperCarnosine and anserine: research background
Research topic: A review of imidazole dipeptides and fatigue research.
Summary — Introduces carnosine and anserine and discusses two human studies related to fatigue. This is early background literature, not a complete account of current evidence.
Japanese Journal of Complementary and Alternative Medicine, 6(3):123–129. DOI: 10.1625/jcam.6.123
Read the paperChicken essence and mental fatigue: a small human trial
Research topic: Repeated chicken essence intake and cognitive performance after mental fatigue.
Summary — Twenty healthy men took part in a placebo-controlled crossover trial. At weeks 1 and 4, reaction times after the post-fatigue rest period were shorter than at baseline; those before and immediately after the fatigue task were unchanged. Placebo showed no comparable significant change, but this alone does not establish superiority over placebo or identify a responsible ingredient.
