Evolution not revolution: Why the immune health ‘surge’ is built on solid foundations
As brands (and consumers) clamor to the immune health space, those that focus on trust, transparency and scientific substantiation will excel.
COVID-19 has shaken the world, affecting people, countries and industries in often devastating ways. In the nutrition industry, considerable focus has been placed on the resulting spike in interest in products offering benefits for immune health. Sometimes this is presented as a sudden transformation—even the U.K.’s Royal Society of Chemistry talked about an “immunity revolution trend.” However, demand for immune health solutions isn’t a new phenomenon. Consumers’ attitudes haven’t changed overnight; they still have the same fundamental concerns, needs and preferences—and increasing demand is rooted in foundations that long precede the current crisis. Understanding these considerations is key to success in the increasingly crowded immune health space.
There’s been a “surge”…
Unsurprisingly, 2020 has seen a major acceleration of consumer interest in the role of nutrition in immunity, with a 670% increase in Google searches for “food” and “immune system” between February and March. FMCG Gurus data indicated 50% of consumers worldwide have begun eating foods that boost their immune health more frequently since the pandemic. Nearly a quarter (23%) surveyed for Globaldata stated they are buying more vitamins and supplements or stockpiling them. Reflecting that, the immune vitamin dietary supplement market has seen substantial growth, with U.S. sales increasing by 25% in 2020, according to Nutrition Business Journal (NBJ).
The spike in immune health interest is one element of a more proactive approach to protection against illness generally. The FMCG Gurus survey found that 84% of consumers now plan to make greater attempts to stay healthier in the future.
…but the foundations have long been in place
However, interest in immune health was very high, and continuing to rise, before the current pandemic. According to Kerry’s global consumer survey—conducted in 2019—immune system support was the most common reason for consumers to buy healthy lifestyle products. Mintel data showed that between 2015 and 2020, global food and drink launches with immune health claims increased by a compound annual growth rate (CAGR) of 8.2%, and for vitamins and dietary supplements with immune health claims, the figure was 13.6%.
This market growth has been supported by a mainstreaming process, with products for immunity increasingly promoted by retailers. Channels such as Walmart and Amazon, for example, have been giving them more visibility by flashing separate immunity sections on their web pages.
Transparency – Not optional
The ubiquity of smartphones means consumers now have a near-instant ability to learn everything about what a brand is selling and where it comes from, along with accessing online reviews that can make or break a product. All this means brands have nowhere to hide and transparency is not optional.
Meanwhile, consumers are more knowledgeable, more skeptical and more likely to ask questions about the claims made for immune health products. FMCG Gurus research showed that over half (57%) of global consumers want more information about the nutritional benefits of products.
Our own research revealed the importance of transparency in healthy lifestyle products. Half (48%) of consumers in China, and 50% of those in Mexico, for example, said they would be encouraged to buy a product after seeing the benefits explained and supported on packaging.
Research brings reassurance
FMCG Gurus also reported that almost half (47%) of consumers said they regularly research ingredients to help make their choices. Again, this hunger for scientific substantiation is part of a trend that precedes the COVID-19 crisis. Two in five (39%) of the consumers we surveyed in 2019 said seeing research or scientific data claims would make them more likely to buy a healthy lifestyle product. Indeed, research was the top driver for choosing healthy lifestyle products worldwide.
In this climate, clinically supported ingredients offer a significant competitive advantage, as do branded ingredients, which can help companies tell a benefit-driven story that consumers can understand and trust.
Yeast beta-glucans: Supported by science
Consumer demand for safe, natural and clinically proven immune health products is fueling growing interest in the benefits of yeast beta-glucans. Many beta-glucan varieties are available; naturally found in foods such as baker’s yeast, shiitake mushrooms and cereal grains, each has a different structure and potential health effects. Oat beta-glucans, for example, are commonly associated with heart health and helping to manage low-density lipoprotein (LDL) cholesterol.
A growing body of research shows certain yeast beta-glucan strains can play an important role in supporting immune health. A recent review of multiple clinically supported studies indicated that immunomodulators present in some yeast beta-glucans may “train” the body’s immune cells to react more quickly when a pathogen is detected.1
Growing evidence suggests yeast beta-glucans may be uniquely positioned to support immune health—but not all baker’s yeasts provide the same advantages. The strain, as well as the method of beta-glucan extraction, can affect the benefits for the immune system.
Wellmune is a proprietary baker’s yeast beta 1,3/1,6 glucan backed by a long history of research. Its ability to enhance immune cell response was first discovered in 2002, and a study two years later revealed its mechanism of action.2 Its structure and strain-specific efficacy have now been studied extensively, with more than a dozen published, peer-reviewed studies supporting its ability to help improve immune health.
