In Your 60s: What to Know About Supporting Immune Health

Have you noticed that a common cold seems to linger longer than it used to? Entering your 60s brings real changes to the immune system. As we age, the responsiveness and efficiency of immune cells gradually decline, a process known as immunosenescence. This is a normal physiological change, not a disease in itself. Even so, this is a good time to be more proactive about vaccinations, daily habits, and nutrition.

A CDC-Based Vaccine Checklist

If you live in the United States and are in your 60s, it is worth reviewing the following with your doctor.

●       Shingles vaccine: Recommended for adults age 50 and older, even if you have had chickenpox, a previous shingles vaccine, or shingles itself.

●       Pneumococcal vaccine: Recommended for adults age 50 and older. If you have not had this vaccine before, talk with your doctor about the right option for you.

●       RSV vaccine: Recommended for adults age 75 and older, and for adults age 60 to 74 who are at higher risk, such as those with certain chronic conditions.

●       Flu vaccine: Recommended every fall. A high-dose or adjuvanted vaccine is recommended for adults age 65 and older.

●       Tdap (tetanus, diphtheria, pertussis): A booster is recommended every 10 years.

The right timing and eligibility depend on your individual health status, so the safest approach is to check the CDC's adult immunization schedule (cdc.gov/vaccines/adults) and talk with your doctor.

Everyday Habits Worth Building In

Beyond vaccinations, there are daily habits that can support immune health.

●       Sleep: Getting at least seven hours of sleep a night supports healthy immune cell function in adults.

●       Strength training: Strength training at least twice a week helps guard against muscle loss and can also help lower overall inflammation.

●       Gut health: Gut microbial balance is closely linked to immune function, so fermented foods and dietary fiber are worth including.

●       Regular checkups: Managing chronic conditions becomes more closely tied to immune health with age, so regular screenings help you stay on top of underlying issues.

Fucoidan and Immune Function: What the Clinical Research Shows

Fucoidan is a polysaccharide extracted from seaweed that has drawn attention for its connection to immune function.

A randomized, double-blind, placebo-controlled pilot study published in 2021 in the international journal Marine Drugs had healthy adults ingest fucoidan derived from Okinawa mozuku (Cladosiphon okamuranus) for 12 weeks. NK (natural killer) cell activity increased significantly compared with the placebo group (Tomori et al., Marine Drugs 2021, 19(6):340, PMID: 34203925, https://pubmed.ncbi.nlm.nih.gov/34203925/).

NK cells play an important role in the body's innate immune system. This study suggests that fucoidan intake may help support immune function in healthy adults. That said, this is the result of a single pilot study and does not indicate that fucoidan prevents or treats any specific disease.

What to Look for When Choosing a Fucoidan Product

Fucoidan products can vary widely in quality depending on the seaweed source, origin, and purity. Rather than relying on marketing claims, it is worth checking the following directly on the label.

What to check	Why it matters
Seaweed source	Mozuku, mekabu, and bladderwrack each have a different polysaccharide structure, so a blend of two to three seaweed types can offer a more well rounded profile than a single source.
Actual fucoidan content	Check whether the label states the pure fucoidan content, not just the total weight of "fucoidan extract."
Seaweed origin	Water quality standards vary by growing region, which can affect residual heavy metals, so checking the country or region of origin is a reasonable safety step.
High purity (85% or higher)	A purity of 85% or higher is generally needed for the product's effects to be reliable.

Labeled content and product specifications can vary by manufacturer and production batch, so check the most current label and supplement facts panel before you buy.

A Final Word

Your 60s are a good time to pay a little closer attention to what your body is telling you. Reviewing your vaccine schedule, building in basics like sleep and strength training, and considering a clinically studied ingredient when appropriate can all be part of the picture. Since the right approach depends on your individual health, it is best to make these decisions together with your doctor.
