Did you know that more than 70 percent of your immune cells are located in your gut? That makes having a balanced gut flora essential to a healthy immune system and in keeping infections like colds and viruses at bay. 

Factors such as stress, too much alcohol or caffeine and poor nutrition can also compromise immunity. 

The immune system needs a range of nutrients to function optimally – vitamin C, vitamin E, zinc and selenium, to name a few. You should be able to get these nutrients by eating a varied, whole-food diet.

On the other hand, consuming a diet rich in processed foods (like white bread, pastries, pasta, etc.) can feed unwanted bacteria and yeast in your digestive tract, outnumbering the “good” bacteria that supports a strong immune system.

Many health practitioners recommend a high-quality, multi-strain probiotic with between 1 and 15 billion colony forming units (CFUs) to make sure the good bacteria in your gut outweighs the bad. 

In addition to keeping your immune system humming along, research has found that a daily probiotic may also:

  • Improve digestion
  • Increase energy levels  
  • Prevent and treat urinary tract infections  
  • Improve skin conditions such as acne and rosacea
  • Support a more restful sleep
