Power Your Immune System and Your Health

Designed to help maintain healthy immune system function, Zand Immune Fast works with your body when you need it most. Formulated with EpiCor® yeast fermentate, antioxidant vitamin C and zinc for immunity and gut health support, these clinical strength chews help accelerate immune response and immune cell activity quickly so you can feel your best.

Whether you’re juggling work or school deadlines, family or relationship issues and whatever else gets thrown your way, keeping you and your loved ones healthy can be a challenge. Moving at the speed of life can wear you down, and the physical and mental strain could do a number on your immune system and your overall health 

When your body and mind are working hard, you’ll need powerful immune support – and the faster, the better! Formulated to help support a rapid immune response, Zand Naturals Immune Fast formulas optimize immune cell activity to help them go to work within two hours*. 

How Immune Fast Works 

Like you would expect from any high-quality immune support supplement, Immune Fast contains some of the usual suspects – 1000 mg of vitamin C and 11 mg of zinc, plus immune health herbs echinacea or elderberry (depending on which formula you choose) – all powerful ingredients well-researched for their beneficial effect on the immune system. 

Formulated with EpiCor yeast fermentate, Immune Fast also contains antioxidant vitamin C, zinc and echinacea or elderberry for powerful immune system support.

So what makes Immune Fast stand out so far above the rest? It's one key ingredient: EpiCor® fermented yeast. Backed by clinical trials, this powerful yeast fermentate can help support your body’s immune response within two hours* of taking it to help keep you feeling healthy and in control.  

Here's how: In double-blind, placebo-controlled pilot studies, EpiCor has been shown to help increase levels of slgA, an antibody found in saliva and in the mucous membranes of the mouth, nose and eyes. Antibodies may help support the body's natural defenses against pathogens.

EpiCor may support antioxidant activity that can help increase natural killer (NK) cells in the body, a type of white blood cell essential to the proper functioning of the immune system. Finally, research also suggests that Epicor may act as a prebiotic in the digestive tract, providing nutrients to beneficial bacteria and supporting the growth of healthy gut flora.

Clean, Effective Support

Minimally processed, EpiCor is made with nature-derived, plant-based ingredients that undergo a natural fermentation process. In a nutshell, here’s what we know about EpiCor:

  • Can help support a healthy microbiome environment in the gut

Keep Immune Fast on Hand

Immune Fast makes a great addition to any supplement regimen, or may be used on an as-needed basis to provide essential support at the right moment.

Some great times to take Immune Fast include:

  • When Traveling. Airports, train stations and hectic schedules, along with disrupted sleep patterns and different time zones can all take a toll on your immune system. Combine that with exposure to strange foods, unfamiliar environments and all kinds of new people, and you’ll want your daily serving of Immune Fast, well, fast! Take our advice: never travel without it!
  • During Busy Times at Work or School. Again, the operative word here is busy. A heavier-than-usual workload, a rapidly approaching deadline or a major exam can make you forget to take care of yourself. We recommend you fight back by working on finding healthy ways to relax. Then be sure to keep a bottle of these powerful immune support chews on hand.
  • For Seasonal Support. Whether you’re facing those cold winter months or dealing with the spring season, Immune Fast can provide powerful respiratory support.
  • When You’re Feeling Run Down. Are you tired, have low energy or just feel under the weather? There’s no time to waste! Immune Fast is designed to go to work within two hours** of taking it to optimize your body’s immune response and keep you feeling your best
