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

Many individuals may report feeling physically and mentally depleted following the winter months. (Melrose 2015) Therefore, springtime offers a unique opportunity for practitioners to support their patients’ wellness. Seasonal allergies, upper respiratory tract infections, digestive health concerns, and depression are common health concerns that may affect patients this time of year. 

In combination with healthy behavioral changes, including adhering to a healthy diet, engaging in daily physical activity, obtaining optimal sleep, and managing stress levels, the following evidence-based dietary supplement ingredients may support general wellness this spring and beyond. 

While there are many ingredients that may be considered part of a wellness protocol, the Integrative Medical Advisory Team (IMAT) has selected these based on general safety, effectiveness, and broad applicability and availability to the adult population.

Vitamin D

400-3000 IU per day for ~6 months. (Gao 2017)(Jolliffe 2021)(NIH 2021) Upper limit (UL) of vitamin D is 4,000 IU per day (NIH 2021)

  • Immune health: A 2021 meta-analysis (MA) of 46 randomized controlled trials (n=75,541) found that 400-1,000 IU/day of vitamin D safely reduced acute respiratory infection (ARI) risk by 8%. (Jolliffe 2021) Vitamin D may also play a role in autoimmune health. (Antico 2012)
  • Allergies: 50,000 IU (as vitamin D pearl) per week with concomitant cetirizine for 8 weeks to adults with vitamin D deficiency reduced symptom severity for rhinorrhea, nasal itching, sneezing, and postnasal drip after 8 weeks but not after 4 weeks compared to cetirizine alone. (Bakhshaee 2019
  • Mood: A 2019 meta-analysis found an association between vitamin D and moderate effect size improvements in symptoms of major depression. (Menon 2018)

Dosages vary widely across studies and product formulations; depending on the patient’s individual needs.

  • Digestive health: A systematic review of 15 studies involving 1,793 patients found that probiotics reduced pain and symptom severity scores in patients with IBS. (Didari 2015) Another systematic review of 43 RCTs found that probiotics reduced the risk of persistent symptoms compared to placebo (RR 0.79); benefits were seen among global IBS, abdominal pain, bloating, and flatulence scores (Ford 2014)
  • Immune health: 1 billion CFU of Lactobacillus paracasei 8700:2 (DSM 13434) and Lactobacillus plantarum HEAL 9 (DSM 15312), once per day for 3 months (Berggren 2010) reduced the incidence of developing more than one common cold episode and number of days with a cold, reduced total symptom scores and pharyngeal symptoms, and reduced B lymphocyte proliferation (Berggren 2010)
  • Allergies: A systematic review and meta-analysis found that supplementation with probiotics improved Rhinitis Quality of Life (RQLQ) scores compared to placebo; however, probiotics had no effect on Rhinitis Total Symptom Scores (RTSS) or total IgE levels. (Zajac 2015)

Omega-3 fatty acids (EPA/DHA)

2-4 g EPA + DHA daily for a minimum of 3 months

  • Mood: A 2021 meta-analysis found omega-3 supplementation to benefit depressive symptoms regardless of severity; subgroup analyses identified possible additional benefits with lower severity (no, or mild-moderate depression), and with longer treatment duration (>12 weeks). (Wolters 2021)
  • Cardiovascular disease: A 2020 Cochrane review of 86 RCTs (n=162,796) concluded EPA+DHA reduced coronary heart disease mortality (10%), but not overall risk of CVD (primary or secondary), or all-cause mortality, noting that high intake of EPA+DHA vs. low decreased triglycerides by 15%. (Abdelhamid 2020)
  • Cognitive function: Omega-3 fatty acid supplementation increased short-term memory only in populations with low baseline omega-3 status, (Cooper 2015) and episodic memory in adults with mild memory complaints. (Yurko-Mauro 2015)

25-50 mg per day, (Yosaee 2022)(Faghfouri 2021)(Mousavi 2018) or 75-100 mg of elemental zinc as zinc acetate or zinc gluconate lozenges, once per day, within 24 hours symptom onset if used for acute common cold symptoms. (Hemilä 2017)(Hemilä 2017)

Zinc in the Fullscript catalog


 325-​​400 mg per day (NIH 2021)(Zhao 2019)(Li 2016) for a minimum of 8 weeks (Mah 2021)

  • Headaches: A 2020 meta-analysis demonstrated that magnesium reduced the intensity and frequency of migraine relapses in patients who experience migraine headaches. (Veronese 2019)
  • Sleep: Sleep latency was found to be significantly reduced by magnesium supplementation in a 2021 meta-analysis where < 1000 mg of elemental magnesium three times per day was recommended. (Mah 2021)
  • Mood: A systematic review found dietary magnesium levels to be associated with lower depressive symptoms, and indicated possible use of oral magnesium supplementation as an adjunctive therapy. (Derom 2013)
