Protocol development in integrative medicine is not typically a simple process. Individuals require individualized care, and what works for one patient may not work for another.

To establish these protocols, we first developed a Rating Scale that could be used to discern the rigor of evidence supporting a specific nutrient’s therapeutic effect.

The following protocols were developed using only A through C-quality evidence.

Qualifying studies
Minimum requirements
Systematic review or meta-analysis of human trials
RDBPC human trials
2+ studies and/or 1 study with 50 + subjects
RDBPC human trials
1 study

Physiological responses to surgical procedures impact various outcomes such as length of hospital stay and risk of postoperative complications. (6)(12)(18) Targeting mechanisms that help regulate inflammation and immune function is key to an integrative treatment plan. 

Regulation of post-surgical immune function and inflammation may be achieved through decreasing pro-inflammatory cytokines, such as tumor necrosis factor (TNFα) and interleukins. (9)(24)(19) It is hypothesized that gene expressions of TNF and interleukin-6 (IL-6) are correlated with the gene expression of suppressor of cytokine stimulation-3 (SOCS3), providing insight into the possible mechanism through which decreased inflammation is achieved. (6)

Decreasing oxidative stress may also improve the inflammatory response. Focusing on maintaining adequate plasma and RBC glutathione levels, as well as a favorable glutathione to glutathione disulfide ratio, assists in the attenuated loss of antioxidants. (4) Additionally, interventions aimed at improving neutrophil phagocytosis show potential in upregulating immune function post-operatively. (1)

The ingredients presented in the protocol below reflect research findings that demonstrate the efficacy of dietary supplements when used to support physiological function following surgical interventions.


Specific probiotics strains may reduce the incidence of common postoperative complications such as infection. However, outcomes are dependent on type of surgery, demographic, strain, and dosing. Listed below are three possible strain combinations with associated outcomes. (2)(7)(10)(24)

Strain combination 1

30 billion CFU of Bifidobacterium bifidum, Bifidobacterium infantis, Bifidobacterium longum, Lactobacillus acidophilus, Lactobacillus casei subsp, Lactobacillus lactis, twice per month, 6 months beginning 4 weeks post-surgery

  • Scenario: postoperative complications in colorectal cancer (24)
    • Reduced inflammation, demonstrated by decreased serum levels of TNFα and interleukins IL-6, IL-10, IL-12, IL-17A, IL-17C, and IL-22 when compared to placebo
Probiotic strain combination 1 in the Fullscript catalog

Strain combination 2

Probiotic strain combination 3 in the Fullscript catalog


800 mg magnesium oxide (240 mg elemental magnesium), once per day, from admission to discharge, or 2 g (or 5-50 mg/kg) of intravenous magnesium in the form of levulinate, gluconate, sulfate, or chloride, on day of surgery (3)(8)(11)(12)

  • Incidences of hypomagnesemia, associated with high occurrences in cardiac surgery, were decreased by 29.3% in oral magnesium oxide supplementation, demonstrating an overall decrease in postoperative complications; additionally, reduced gastrointestinal incidences of nausea, vomiting, and constipation in postoperative coronary artery bypass graft surgery when compared to control (12)
  • Decreased postoperative ventricular dysrhythmias, ventilatory support, and increased stroke volume in postoperative cardiac patients treated with intravenous magnesium chloride (3)
  • Systematic review of 14 randomized trials found perioperative magnesium supplementation decreased the risk of postoperative shivering (11)

 0.18-0.4 g/kg, once per day, 1-7 days subsequent to surgery (1)(16)(22)

  • Improved immune function as demonstrated by increased neutrophil phagocytosis, as well as maintained muscular protein synthesis as measured by muscular ribosomal concentration, which is typically reduced following surgical trauma in postoperative colorectal cancer patients (1)
  • Increased T-cell DNA synthesis, indicating enhancement of T-cell function in postoperative colorectal resection (16)
  • Improved immunodepression and nutrition response as well as decreased inflammation in gastrointestinal surgery (22)

Omega-3 fatty acids

0.1-0.2 g/kg once per day of omega-3 fatty acids, seven days subsequent to surgery (1)(9)

Note: Changes in blood flow or coagulation related to altered levels of fibrinogen, factor V, and triglycerides may occur in select populations (13)(14)(20)

  • Neutrophil phagocytosis increased for postoperative colorectal cancer patients whose standard total parenteral nutrition was supplemented with omega-3 fatty acids
  • Postoperative immune function improved and inflammation as indicated by lower levels of IL-6, TNFα, and C-reactive protein in postoperative colorectal cancer patients who had a radical resection; additionally, length of hospital stay decreased (9)
  • Meta-analysis of 16 randomized controlled trials found omega-3 fatty acid emulsion improved immune function, inflammation, and postoperative curative effect in postoperative gastrointestinal cancer (25)
  • Decreased risk of olfactory loss in patients undergoing endoscopic resection for sellar or parasellar tumors (21)
