Brief summary: This phase I clinical trial tests the immune effects of fermented wheat germ in patients with advanced solid tumor cancers who are being treated with standard of care checkpoint inhibitors. Fermented wheat germ is a nutritional supplement that some claim is a "dietary food for special medical purposes for cancer patients" to support them in treatment. There have also been claims that fermented wheat germ is "clinically proven" and "recognized by medical experts" to "enhance oncological treatment" and boost immune response to cancer; however, there are currently no documented therapeutic effects of fermented wheat germ as a nutritional supplement. Checkpoint inhibitors, given as part of standard of care for advanced solid tumors, are a type of immunotherapy that may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. The information gained from this trial may allow researchers to determine if there is any value of giving fermented wheat germ with standard of care checkpoint inhibitors for patients with advanced solid tumor malignancies.

Detailed description: PRIMARY OBJECTIVE: I. To assess the effect of fermented wheat germ (FWG) nutritional supplementation on natural killer (NK) cell killing activity in peripheral blood of cancer patients being treated with standard of care (SOC) immunotherapy who have voluntarily decided to take the FWG nutritional supplement.

SECONDARY OBJECTIVES:

I. To assess immunologic effects of FWG in subjects with cancer treated with checkpoint inhibitor (CPi)-based therapy.

II. To archive stool specimens of subjects with cancer treated with CPi-based therapy for future non-interventional studies for subsequent analysis at completion of study.

III. To evaluate toxicities of FWG in subjects with cancer treated with checkpoint inhibitor (CPi)-based therapy.

IV. To assess immunologic effects of FWG in patients with cancer treated with CPi immune-oncology-based therapy (Immune Correlates).

Eligibility criteria: Inclusion Criteria:

* Histologically or cytologically confirmed non small cell lung carcinoma (NSCLC), renal cell carcinoma (RCC), melanoma, colorectal carcinoma (CRC) and triple-negative breast cancer (TNBC) solid tumor malignancies deemed appropriate to receive standard-of-care checkpoint inhibitor (CPi)-based therapy
* Age \>= 18 years of age at time of consent
* Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (Karnofsky \>= 60%)
* Life expectancy of greater than 6 months
* Women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) for the duration of study participation (including dosing interruptions) and for 5 months (150 days) after the last dose of study agent. Women must agree to refrain from egg donation during this timeframe
* Male subjects must agree to employ an effective method of birth control starting dose from cycle 1 day 1, including dosing interruptions through 90 days after receipt of the last dose of fermented wheat germ (FWG). Male subjects must agree to refrain from sperm donation while taking FWG during study treatment for at least 90 days after the last dose of FWG
* Ability to understand and the willingness to sign a written informed consent document
* Must be able to swallow study treatment

Exclusion Criteria:

* Prior allogeneic bone marrow transplantation or solid organ transplantation
* Chemotherapy or radiotherapy within 2 weeks (6 weeks for nitrosoureas or mitomycin C) prior to cycle 1 day 1. However, the following therapies are allowed: \* Hormone-replacement therapy or oral contraceptives \* Herbal therapy intended as anticancer therapy must be discontinued for at least 1 week prior to enrollment)
* Any subject who have not recovered to at least grade 2 from adverse events (other than alopecia) due to agents administered more than 2 weeks earlier. Treatment with any other investigational agent within 3 weeks
* Currently taking FWG
* Treatment with systemic immunostimulatory agents (for example, interferon \[IFN\]-alpha or interleukin \[IL\]-2) within 6 weeks prior
* Current or prior use of immunosuppressive medications (for example, corticosteroid, cyclophosphamide, azathioprine, methotrexate, thalidomide, calcineurin inhibitors, and anti-tumor necrosis factor \[anti-TNF\] agents) within 14 days prior to first dose of FWG. The following are exceptions to this criterion: \* Intranasal, inhaled, topical or local steroid injections (e.g., intra-articular injection); steroids as premedication for hypersensitivity reactions; systemic corticosteroid at physiologic doses not to exceed 10 mg/day of prednisone or equivalent may be enrolled \* Patients who have received acute, low dose, systemic immunosuppressant medications (e.g., a one-time dose of dexamethasone for nausea) may be enrolled \* The use of inhaled corticosteroids and mineralocorticoids (e.g., fludrocortisone) for patients with orthostatic hypotension or adrenocortical insufficiency is allowed
* Patients taking bisphosphonate therapy for hypercalcemia. Use of bisphosphonate therapy for other reasons (e.g., bone metastasis or osteoporosis) is allowed
* Known history of allergic reactions or sensitivity attributed to compounds of similar chemical or biologic composition to the study agent (e.g., gluten)

* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would interfere with patient safety or limit compliance with study requirements
* Female subjects who are pregnant or breast-feeding
* Any condition that would prohibit the understanding or rendering of informed consent in the opinion of the investigator
* Prior intolerance to checkpoint inhibitor (CPi)-based therapies
* Any medical condition that in the opinion of the investigator would interfere with the patient's safety or compliance while on trial
