The Science Behind Pharma Plus Active Immune: Why We Chose Wellmune®

When we developed Pharma Plus Active Immune, we wanted to create more than just another immune supplement. Every ingredient was carefully selected based on quality, scientific evidence and purpose.

That's why we chose Wellmune®, a premium branded ingredient developed by Kerry, one of Ireland's leading nutrition companies. Unlike generic beta glucans, Wellmune® has been extensively researched and is supported by decades of scientific study.

Meet Wellmune®

Wellmune® is a purified fibre extracted from the cell wall of baker's yeast (Saccharomyces cerevisiae). It is a specific beta 1,3/1,6 glucan and is classified as a postbiotic, meaning it is a purified compound rather than a live microorganism.

Unlike probiotics, which contain live bacteria, Wellmune® works by supporting your body's innate immune system – your first line of defence against everyday immune challenges.

According to Kerry, Wellmune® was the first orally consumed ingredient to be clinically researched for its ability to help train the innate immune system.

How Does Wellmune® Work?

Rather than simply "boosting" the immune system, research suggests that Wellmune® helps train the innate immune system to respond more efficiently when needed.

According to published research, Wellmune® supports key innate immune cells, including macrophages and neutrophils, by helping them use and store energy more efficiently. This helps prepare these important first responder cells to react when the body encounters everyday immune challenges.

Recent studies led by Dr Brian McFarlin (2024–2025) have shown that Wellmune® activates important immune signalling pathways without overstimulating the immune system, supporting a balanced and proactive immune response.

Backed by Extensive Clinical Research

One of the reasons we selected Wellmune® is the strength of the science behind it.

According to Kerry, Wellmune® is the most clinically researched yeast beta glucan postbiotic available today, supported by:

• More than 50 published scientific studies.
• Over a dozen human clinical trials.
• Research involving almost 2,000 adults and children.
• Studies across a variety of groups, including children, athletes and adults experiencing everyday stress.

Wellmune® also holds Generally Recognized as Safe (GRAS) status from the US Food and Drug Administration (FDA) and is used in immune health products in more than 60 countries worldwide.

Not All Beta Glucans Are the Same

You may have seen "beta glucan" listed on supplement labels, but not all beta glucans are created equal.

Beta glucans can be sourced from oats, mushrooms, algae and yeast. Each source has a different molecular structure, purity and branching pattern, and research shows these differences influence how the body responds.

The clinical studies behind Wellmune® relate specifically to its unique yeast-derived beta 1,3/1,6 glucan and Kerry's proprietary purification process. When a supplement simply lists "beta glucan" without identifying the source, there is no guarantee it carries the same level of scientific research.

That's why we specifically formulated Pharma Plus Active Immune with Wellmune® rather than a generic beta glucan ingredient.

Why We Include Wellmune® in Pharma Plus Active Immune

Every ingredient in Active Immune has been carefully selected to work together as part of a comprehensive daily immune support formula.

Our formula combines Wellmune® with:

• Vitamin C
• Vitamin D
• Zinc
  
• B Vitamins
• Elderberry Extract

Vitamins C and D, and zinc contribute to the normal function of the immune system, while Wellmune® was selected because of its extensive clinical research and premium quality.

The result is a thoughtfully formulated supplement that combines evidence-based ingredients with pharmacist expertise.

Why Ingredient Quality Matters

At Pharma Plus, we believe what's inside your supplement matters just as much as what's on the label.

There are many immune supplements available, but not all ingredients are created equal. We believe in using branded, clinically researched ingredients wherever possible because they provide consistency, quality and confidence.

Wellmune® is trusted by leading nutrition brands around the world because of its quality, purity and extensive scientific backing.

We don't include ingredients simply because they're trending. Every ingredient in Active Immune has been selected for a reason, so you can feel confident you're choosing a supplement built on quality and evidence.

The Bottom Line

Pharma Plus Active Immune combines scientifically researched ingredients with pharmacist expertise to support your everyday wellbeing.

By choosing Wellmune® instead of a generic beta glucan, we've selected an ingredient backed by decades of research, extensive clinical studies and trusted worldwide for its quality.

Because when it comes to supporting your immune system, quality ingredients matter.

Important Information

Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle.

Vitamin C, Vitamin D, Zinc and Folate contribute to the normal function of the immune system.

Always take food supplements as directed. If you are pregnant, breastfeeding, taking medication or have a medical condition, consult your healthcare professional before use.
