Immunity is a key category which represents an estimated $2 billion of the American supplement market (about 11% of market share). According to Innova Market Insight, between 2013 and 2016, there was an 80% rise in new product launches positioned for immunity. 
 
There is a strong link between immune health and gut health. After the skin, the intestine is the main natural barrier against external factors. Products combining gut health and immune claims are well understood by consumers. Considering all these market elements, Nexira has launched its new branded ingredient Immunell combining a natural yeast extract and prebiotic acacia fiber. 
 
Manufactured in France, Immunell is a natural and safe ingredient derived from a yeast (Saccharomyces cerevisiae) containing nucleotides, the company said. With a high purity rate, higher than 60% of nucleotides, Immunell is a unique source of the four semi-essential nucleotides (Adenine, Cytosine, Guanine, and Uracil) and formulated with prebiotic acacia fiber. 
 
Naturally occurring in food and breast milk and found in all living cells of the body, nucleotides are semi-essential molecules supporting organ growth, immune system, and intestinal function. 
 
Immunell is an overall support for immunity, from innate immune response to adaptive immune response. Main actions include:
 

• Support cellular regeneration 
• Reinforce the gut barrier 
• Improve the immune system 

 
Nucleotides have been used for years in nutrition to support organ growth, immune system, and intestinal function. Certain demanding conditions (stressful lifestyle, strenuous workout, etc.) or certain organs (fast renewal tissues like the intestines) can lead to a high need of nucleotides. With this new ingredient, Nexira offers an easy and safe way for supplementation, the company said.
