Immune Support

Your immune system plays a critical role in keeping you healthy—and certain times of year, this is a heavier lift than others. Long hours indoors during the winter months are notorious for immune health challenges; that's not to say that the warmer months don't come with their own struggles, too.

That's why you need a stay-well strategy, so your natural defenses will be in tip-top shape, no matter what the day (or season) sends your way. Be proactive about your immune health by living an active, healthy lifestyle, eating a well-balanced diet and incorporating immune support supplements like zinc, vitamin C and elderberry, along with a high-quality probiotic, into your wellness routine.

Immune Support Vitamins: Vitamin C

When you need a little extra support for your immune system, turn to an immune support vitamin like vitamin C. Scientifically validated for its immune health benefits, vitamin C helps lessen the duration and response to immune system challenges. Vitamin C also provides powerful antioxidant protection, empowering your cells to fight against free radicals.

Immune Support Supplements: Zinc

For maximum immune health support, turn to zinc. As you age, your zinc levels decline, making it harder for your body to defend itself against challenges. That's why zinc is an especially crucial immune health supplement for the elderly. No matter what your age, though, this mineral is a must-have if you're concerned about staying well!

Probiotics for Immune System Support

Our immune system is our body's built-in first line of defense when it comes to fighting off the challenges posed by foreign substances such as pollen. Probiotics provide powerful immune support because they promote the natural production of immunoglobulin A, an essential part of your body's immune defenses. Probiotics formulated specifically for immune health may also help support healthy nasal flow function by protecting your airflow—stopping pollen in its tracks from activating your immune system.
