How Aging Impacts The Immune System
Posted on Oct 22, 2021

As we get older, many of our bodily functions begin to slow down or become less efficient. Joint mobility, vitamin absorption, bone and wound healing, and more are all affected. But perhaps the most important function that can be impacted is immunity.

The effects of aging on the immune system are manifest at multiple levels that include reduced production of B and T cells in bone marrow and thymus and diminished function of mature lymphocytes in secondary lymphoid tissues. As a result, elderly individuals do not respond to immune challenges as robustly as the young.”

The true causes of altered immunity with ageing have not been fully described. However, accumulation of cellular damage from oxidative stress and the lack of essential vitamins and micronutrients seem to play a very large role.


Your immune system doesn’t just protect you from outside invaders. That’s it’s most well-known and one of the most important functions, but your immune system handles much more than that.

There are two main parts of the immune system: the innate immune system (which you’re born with) and your adaptive immune system, which you develop over time as your body is exposed to viruses, illness, or other microbes.

The innate immune system is a “rapid response” system. It patrols the body and is the first to respond once it finds an invader. It immediately engulfs the invader, and whatever virus or infection is present is killed within these immune system cells (phagocytes.)

The acquired immune system produces antibodies that protect your body from specific types of illness and infection. Antibodies are literally that. They are proteins that act against another protein.

The lymphocyte will recognize a protein from a virus or bacteria and that protein recognition triggers the production of antibodies against that protein and thus that pathogen. This is the basis of our immune systems that we begin building as we drink our mothers’ milk.

When you get a vaccine, your body is learning about a virus and producing specific antibodies to protect you from it. A vaccine merely utilizes existing machinery of the natural immunity you are capable of producing.

Dr. Meredith Warner is a board-certified orthopedic surgeon with a thriving private practice in Louisiana, USA. Her practice allows her the freedom to treat patients in the best way possible – on an individual basis. It has always been her goal to seek non-operative treatment and functional recovery over surgical or heavy pharmaceutical means of healing.

This is why Dr. Warner developed her Bone & Joint Multivitamin. This proprietary blend contains the essential vitamins and minerals she recommends for her patients’ pre- and post-op regimens. She handpicked each ingredient in this Multi to boost musculoskeletal health, help reduce joint + muscle inflammation, and promote full-body wellness.


  1. Fighting off pathogens. Your immune system fights off bacteria, germs, and viruses you come into contact with every day in the manner described above.
  2. Fighting and removing toxins. Your immune system is responsible for fighting off dangerous substances you come into contact with in your environment. This means that your body is involved in producing antioxidants, which help neutralize free radicals. Often, free radicals (reactive oxygen species) form as a result of a toxic insult to cells.
  3. Fighting off abnormal changes in your body. For example, your immune system is involved in fighting off malignant proliferation of cells that can lead to cancer. The immune system plays an important role in maintaining healthy dynamics of cell death and regeneration in order to maintain your health.
  4. Managing and allowing us to heal after injury. The innate immune system is involved with cleaning up debris such as dead or damaged cells. The immune system as a whole is heavily involved in the healing process for all of our systems after an injury.


One of the best ways to support immunity is to ensure you’re getting the right nutrition, with the correct amount of vitamins – and to avoid inflammatory foods in your diet (like processed foods, simple carbohydrates, excess sugar, and more.)

Unfortunately, many of us aren’t getting the essential vitamins and minerals we need to protect our healthspan (the amount of years we live healthy, vibrant lifestyles.) That’s where supplementation can provide powerful benefits. Healthspan is heavily dependent upon the longevity of the immune system of course.


Our Immune Boost Multi is formulated with clinically high doses of vitamins D and C to support your immune system’s function. This multi provides essential nutrients your body needs to function properly to regulate its own inflammatory/immune response – and contains a plant-based phytochemical ingredient to provide a powerful antioxidant punch.

Quercetin is a phytonutrient that is highly antioxidant. The group of phytonutrients it’s part of is known for being potent anti-inflammatories and antioxidants that may exert modulating effects on the immune system.

The antioxidant properties of quercetin can help safeguard your cardiovascular health, and bolster your defenses against “lifestyle” diseases like diabetes and certain cancers. Quercetin itself functions to neutralize reactive electrons attached to molecules – so called ‘free radicals’. This is one of the main ways it acts to protect us.

Also, this study found that “short-term high doses of quercetin and resveratrol alters aging markers in human kidney cells.”

Our surgeon-formulated Immune Boost Multi is ideal for those looking to optimize their immune function, boost respiratory health, decrease cardiovascular strain, and more.
