Introduction

In the intensive care unit (ICU), patients experience extreme metabolic stress, inflammation, muscle wasting, and impaired immunity. ^1,2 To support recovery, ICU nutrition must move beyond calories to deliver targeted, therapeutic nutrients that restore core physiological functions.

1. Whey Protein Peptide + Isolate + Concentrate: The Muscle Shield

Critical illness causes rapid loss of lean body mass, and whey protein is a high-quality, fast-digesting source of essential amino acids, especially leucine. Core11 uses a tri-blend of:

• Whey Peptides: Pre-digested for fast absorption ³
• Whey Isolate: High purity with minimal lactose and fat ⁴
• Whey Concentrate: Retains immunoglobulins and growth factors ⁵

This combination supports muscle synthesis, reduces catabolism, enhances immune function, and accelerates post-ICU recovery.

2. Omega-3 Fatty Acids: Anti-inflammatory Backbone

Omega-3s (EPA/DHA) reduce pro-inflammatory cytokines, improve gas exchange, and lower ventilator days. ⁶ They aid in resolving systemic inflammation and improving outcomes in sepsis and ARDS patients. ⁷

3. HMB (Beta-hydroxy beta-methylbutyrate): Muscle Preservation Molecule

HMB promotes protein synthesis through mTOR activation and suppresses protein breakdown. ⁸ Especially effective when combined with whey protein to prevent ICU-induced sarcopenia. ⁹

4. Bovine Colostrum: Gut and Immune Restoration

Rich in immunoglobulins, lactoferrin, and epithelial growth factors, colostrum helps repair the gut barrier, modulate immunity, and reduce translocation of pathogens. ¹⁰ It also supports mucosal healing in critical illness. ¹¹

5. Probiotics: Microbiome Modulation

Critical illness disrupts gut flora, contributing to systemic infections. Probiotics like Lactobacillus rhamnosus and Bifidobacterium longum reduce the risk of ventilator-associated pneumonia and support immune homeostasis. ¹²

6. Digestive Enzymes: Enhanced Absorption

Malabsorption is common in ICU patients. Digestive enzymes (protease, amylase, lipase) enhance nutrient breakdown and reduce feeding intolerance, ensuring patients receive the full benefit of nutritional support. ¹³

7. Peptide-Based Formulation: Better Tolerance, Faster Delivery

Peptide-based enteral feeds improve nitrogen retention and are better tolerated in critically ill patients with impaired digestive capacity. ¹⁴ They help minimize diarrhea and gastric residuals.

8. Synergistic Nutrition: Why It Works Together

Combining these elements targets muscle, immune, gut, and metabolic recovery simultaneously. The synergy between whey protein + HMB, omega-3 + colostrum, and probiotics + enzymes leads to better ICU outcomes.

9. Clinical Guidelines and Recommendations

• ESPEN and ASPEN recommend immunonutrition in specific ICU subsets (e.g., trauma, sepsis)
• Use of omega-3, peptides, probiotics, and glutamine is supported by current evidence
• Timing, monitoring, and tolerance are essential to outcome success

10. Conclusion

ICU patients need more than calories—they need science-backed, precision nutrition. Core11’s Entrifed CC brings together whey peptides, HMB, omega-3s, colostrum, probiotics, and enzymes to support full-spectrum ICU recovery.
