During super flu season, seniors are more vulnerable to severe illness and longer recovery. This article highlights science-backed home remedies and commonly discussed supplements that support immune health, with expert insights from WABC Radio contributor Dr. Peter Michalos and United Hebrew’s clinical perspective.

As we move through peak flu season, respiratory illnesses are spreading more widely and more intensely than in recent years. For older adults, the flu can lead to longer recovery times, complications, and hospitalizations. While prevention strategies such as vaccination, hand hygiene, and medical treatment remain essential, many seniors and families are also asking what else can help support immune health.

According to Dr. Elaine Healy, geriatric physician and medical director at United Hebrew, immune support in older adults is most effective when it combines preventive medical care with nutrition, hydration, and early symptom management. She emphasizes that even mild infections can have a greater impact on seniors, making consistent, proactive wellness habits especially important during flu season.

Recently, Dr. Peter Michalos spoke with John Catsimatidis on WABC Radio’s “Cats Roundtable” about the science behind traditional home remedies and supplements that have been studied for their role in immune health. His insights help explain why certain natural approaches continue to be discussed, particularly as complementary supports during cold and flu season.

Why Chicken Soup Really Helps

Chicken soup has long been considered a comfort food when you are sick, but its benefits are rooted in science. According to Dr. Michalos, chicken soup contains a compound called carnosine, which helps reduce inflammation and congestion in the nasal passages.

Chicken soup is also rich in vitamins A and C, magnesium, phosphorus, and antioxidants. These nutrients support immune function and hydration, which are critical when the body is fighting infection. Warm liquids can also help soothe sore throats and encourage fluid intake, an important factor in recovery for older adults.

Garlic and Immune Defense

Garlic has well-documented medicinal properties. Dr. Michalos explains that garlic contains allicin, a compound that supports immune health by helping slow the entry of viruses into cells. This may reduce both the severity and frequency of illness.

Adding fresh garlic to meals during flu season is a simple way to support immune health while enhancing flavor and nutrition.

Elderberry and Symptom Relief

Elderberry is a natural remedy that has gained attention for its potential immune benefits. When cooked properly, elderberry provides flavonoids along with vitamins A and C. These compounds help reduce inflammation and support immune response.

Some studies suggest elderberry may help lessen the severity and shorten the duration of cold and flu symptoms. As with any supplement, older adults should consult their healthcare provider before use, particularly if they take prescription medications or manage chronic conditions.

Zinc, Copper, and Early Protection

Zinc plays a role in helping prevent viruses from entering the body through the mouth and nose. Dr. Michalos notes that zinc is often combined with copper because high levels of zinc alone can interfere with copper absorption.

When taken early at the first sign of symptoms, zinc may help slow viral replication. Seniors should follow recommended dosing and speak with a healthcare provider to ensure safe use.

The Role of Gut Health in Immunity

Research shows that approximately 80 percent of immune function is linked to the gut. A balanced gut microbiome helps the body respond more effectively to infections. Dr. Michalos notes that some clinicians discuss soil-based probiotics, which may reflect the diversity of beneficial bacteria humans were historically exposed to through natural environments.

B Vitamins, Vitamin C, and Vitamin D

Several vitamins play an important role in immune support:

- Vitamin B6, found in B-complex supplements, supports white blood cell and T-cell production.
- Vitamin C has been shown in studies to reduce the duration and severity of cold symptoms.
- Vitamin D supports immune response, helps fight viruses and bacteria, and may shorten the length of illness. It also plays a role in mood regulation and bone health, both critical for older adults.

Dr. Healy notes that vitamin D deficiency and gut imbalance are common among older adults, particularly during winter months. Addressing these issues appropriately can support immune response, bone health, and overall resilience, especially when supplementation is guided by a physician who understands an individual’s full health profile.

In addition to vitamin D, Dr. Michalos notes some providers discuss pairing vitamin D with vitamin K2 to support absorption, and zinc to support immune function when clinically appropriate.

Green Tea and Antioxidants

Green tea contains antioxidants and has antiviral properties. Studies show that people who regularly drink green tea tend to experience fewer colds. It also supports hydration and offers a gentle metabolic boost.

For seniors, green tea can be a soothing daily habit that supports hydration and overall wellness during flu season.

Glutathione and Emerging Immune Research

Glutathione is a powerful antioxidant produced naturally in the body. During the COVID-19 pandemic, researchers observed that individuals with severe illness often had low glutathione levels. As a result, some healthcare providers began recommending supplementation to support immune defense and reduce oxidative stress.

While research is ongoing, glutathione is an area of growing interest in immunity health, particularly when evaluated within a broader clinical context.

Supporting Senior Health Through Flu Season & Everyday

At United Hebrew, supporting healthy aging means more than responding to illness. It means creating an environment where older adults feel supported, nourished, and cared for every day through attentive clinical oversight, nutritious meals, wellness programming, and access to expert caregivers. Because everyone’s individual health needs are different, our clinical team focuses on personalized care rather than one-size-fits all solutions, helping residents make informed choices in partnership with their physicians.

For families exploring assisted living or short-term support for a loved one, learning more about United Hebrew’s community and care approach can be an important first step. We invite you to contact us to learn more or schedule a tour and see how our team helps seniors thrive through every season.
