Five Factors that Affect the Immune System

The Immune System's Job: Detect and Destroy

The immune system is designed to detect and destroy foreign invaders inside the body like bacteria and viruses. When working optimally, the immune system can prevent sickness when we’re exposed to germs. Several factors like sleep, diet, stress and hygiene can affect the immune system’s performance, and any offsets in these behaviors can cause havoc on immune function. Often times the impact of these factors go unnoticed, but if you tend to get sick after a big project at work or during finals at school, it’s likely because your immune system has suffered due to stress, lack of sleep, binge eating or unhygienic behaviors.

1. Hand Washing

People tend to overestimate their hygiene. Studies show that only 67% of people wash their hands after using a public restroom, vs. 85% who report washing their hands after public restroom use. 1,2 And even if you do wash your hands, you may not be doing it correctly: Centers for Disease Control recommends 15 seconds of scrubbing your hands with soap, or humming the “Happy Birthday” song TWO TIMES! 1 You should try it - it feels like an eternity when you’re standing in front of a mirror in a public restroom, next to a stranger that you might be trying to avoid talking to.

3. Nutrients From Food

Everywhere we turn, we see PSAs, news stories and blogs boasting the importance of fruits and vegetables for a plethora of health reasons, and the same applies to immune health. Studies show vitamins C, A, E, B6 and B12 and minerals like iron and zinc are important for the maintenance of immune function, all of which can be found in fruits and veggies. 7 If you’re a clean-eating enthusiast, you’re probably getting enough of these vitamins and minerals, but many of us aren’t. The Dietary Guidelines for Americans recommends 4.5 cups of fruit and vegetables per day. 5

5. Supplement Intake

To promote and support healthy behaviors, supplements and fortified foods have been widely used to support immune health. According to Nutraingredients, 29% of supplement users take an immune health product. 11

Beta-glucan is an emerging ingredient in immune health supplements. Beta-glucan is a naturally occurring glucose polymer or insoluble fiber found in cereal grains like oat and barley, certain types of mushrooms, yeast, seaweed, and algae. Although all types of beta-glucan have some health benefit, the beta-glucan found in yeast, mushrooms and algae can provide benefits that support immune health. 10

BetaVia™ Beta-glucan for Immune Support

BetaVia Complete is a beta-glucan ingredient naturally-sourced from Euglena gracilis (algae). In vitro and animal studies show that BetaVia can prime key immune cells, thereby strengthening the body’s immune defenses. Algae-sourced BetaVia is distinct from currently available beta-glucan ingredients that are derived from yeast or mushrooms. True to our commitment to providing science-backed ingredients, Kemin has an ongoing BetaVia research program focused on discovery and innovation to bring cutting-edge science, insights and claims to our customers.
