CELLULAR DEFENCE

Cellular Defence is a must have! I have loved all the Artah products I’ve tried, but Cellular Defence is my must have. I’ve really noticed a difference since taking it and definitely avoid colds from the kids and getting run down as much as I used to.

After getting sick again and again over winter and regular travel I started taking these and haven’t been sick since. Highly recommend!

The Essential Breakdown

Description

Cellular Defence is a comprehensive daily immune support formula designed to help reinforce the body’s natural defences all year round.

The immune system is a highly complex network that protects the body from external stressors while also supporting recovery, repair, and overall resilience. Its effectiveness depends on a wide range of nutrients and bioactive compounds working together, making consistent nutritional support essential for optimal function.

This targeted formula combines a synergistic blend of medicinal mushrooms, botanical extracts, and immune-supportive nutrients to help maintain a healthy and balanced immune response. At its core are Reishi and Astragalus, two traditional adaptogenic botanicals long valued for their role in supporting vitality, endurance, and immune resilience. These are paired with beta glucans, naturally occurring polysaccharides found in mushrooms and yeast that help support immune system readiness and responsiveness.

Alongside these functional compounds, Cellular Defence includes key immune-essential nutrients such as vitamin C, vitamin A, zinc, and selenium, all of which contribute to the normal function of the immune system. Vitamin C supports immune cell activity and antioxidant protection, while vitamin A plays a role in maintaining healthy mucosal barriers. Zinc and selenium are essential trace minerals involved in immune signalling, cellular defence, and antioxidant processes.

Quercetin, a plant-derived flavonoid, provides additional antioxidant support and helps support the body’s natural inflammatory balance, further reinforcing immune function and cellular resilience.

Together, these ingredients provide a multi-layered approach to immune health, combining traditional botanicals with essential nutrients to support everyday resilience, recovery, and wellbeing. Cellular Defence is designed for consistent daily use to help support immune function during periods of stress, travel, seasonal challenges, and year-round exposure to environmental demands.

FAQs

Who should take Cellular Defence?

Anyone who would like to support their immune system. Because it contains Vitamin A, Zinc, Selenium, Quercetin, and immune supporting herbs and mushrooms, Immune Defence is perfect for those who wish to replace many different supplements with one effective formula.

How can I tell if it's working?

You may notice that you aren't getting sick as often and if you do catch something, you may recover more quickly than usual. You may also notice an improvement in energy within the first month of use.

Do I need to take it regularly or can I take it just when I feel like I'm getting sick?

Immune support will be most effective if taken proactively, for example when approaching the winter season, or to bolster your defences if you're run down or exposed to others who are ill.
