Immune support

Let natural support give you strength

The best way to get through the cold season is to take care of your immune system, and supporting a healthy immune response requires fundamental nutrition. Let the power of vitamins and specific nutrients help you get the best of this changing season.

Why support yourself with supplements and vitamins

Your immune system plays a critical role in keeping you healthy in general — and that's why it's important to always make sure it gets the daily support and nurture needed. 

  • Normal aging results in a progressive decline in immune function. Healthy immunity, however, can be supported using nutrients that function via multiple pathways.

  • Frequent colds, difficulty fighting off infections, persistent fatigue, or digestive issues, could be a sign that your immune system could use some support.

  • Long hours indoors during the winter months are challenging for immune health; that's not to say that the warmer months don't come with their own struggles, too.

Why these ingredients are very important

In order to live long, healthy lives, we need our immune system to function at peak form on a daily basis. Optimal immunity requires a daily intake of vitamin C and several other immune-supporting nutrients. You see three of them below and find more here.

Why vitamin C

The activity of many immune cells is closely related to their vitamin C content, and research shows that vitamin C promotes a healthy immune system in a variety of ways. The human body can't produce or effectively store vitamin C. In order to maintain optimal immunity, it’s good to replenish your supply through daily supplementation.

Why zinc is important

Zinc is a powerful mineral that helps keep your immune system functioning at peak performance. But zinc deficiency is common, especially in older people. Your body does not naturally produce zinc, so you need to eat a diet rich in zinc or incorporate a high-quality zinc supplement into your wellness routine to get all its health benefits.

Why vitamin D

Vitamin D (especially vitamin D3) plays a critical role in healthy immune function. It fortifies the immune system, helping to protect the body from infections, and lessening their severity. For most people, diet and sunlight are not enough to maintain optimal vitamin D levels. That means that supplementing with vitamin D is recommended.

Support for the seasonal

During seasonal changes (but also all year round) your immune system might be out of balance. 

The immune system is the body's built-in first line of defense when it comes to fighting off foreign substances such as pollen. Therefore, defending it against these health challenges is important, and you also might have the need to calm down seasonal immune discomforts.

If you are looking for immune defense fortification for seasonal challenges, you might want to give these specifically designed formulas a try:

Nutrients that can impact immunity 

Supplementing with specific nutrients may help defend against infectious agents.

Especially with age, immune function markedly declines along with the body’s natural defenses. And keeping a healthy immune response at certain times of year is a heavier lift than others — no matter age! 

That's why you need a stay-well strategy, so your natural defenses will be in tip-top shape, regardless of what the day (or season) sends your way. The following nutrients can help support a healthy immune response: 

  • Vitamin C helps increase levels of antibody-producing cells (lymphocytes), boosts the function of infection-engulfing neutrophils, and helps NK (natural killer) cell activity. 
  • Quercetin can reduce inflammatory immune cells, cuts histamine levels, relaxes airway smooth muscle, inhibits replication and infectivity of cold-causing viruses, and reduces senescent cells and their pro-inflammatory signaling.
  • Vitamin D interferes with virus replication and modulates the immune response via receptors on various immune cell types, thus supporting antimicrobial defenses while limiting inflammatory signaling.
  • Zinc is key to maintaining the integrity of the immune system. It helps with the normal development and function of natural killer cells, lymphocytes, neutrophils, and macrophages.
  • Probiotics: A probiotic strain, Lactobacillus rhamnosus CRL1505, can significantly boost levels of secretory IgA — critical antibodies that target both viral and bacterial invaders in the upper respiratory tract — thus providing a security system against cold and flu viruses within mucosal membranes. 
  • Lactoferrin is a protein found in milk and produced in tears, saliva, mucus, and by some immune cells. It can help prevent a wide range of pathogens from entering through the linings of the oral cavity, nasal cavity, airways, and digestive system. This includes viruses that cause the common cold
  • Garlic: Aged garlic extract has demonstrated potent antiviral and immune-enhancing properties.
  • Mushrooms contain beta-glucans and other compounds known to activate critical immune functions. Shiitake, maitake, and chaga mushrooms help support the immune system, activating immune cells.
  • Melatonin: In addition to protecting against inadequate sleep, which has a well-documented negative impact on immune health, melatonin provides vital immune support by helping coordinate immune responses to a wide variety of threats, including viruses. So when internal production of melatonin drops with age, it leaves the immune system weakened. During this process, called immune senescence, disease risks rise because the immune system stops eliminating abnormalities properly. Thus supplementing with melatonin may be useful to enhance immunity.
