Frequently Asked Questions

  • Can I take too much 4Life Transfer Factor?
    While 600 mg is the recommended daily dose of 4Life Transfer Factor, exceeding this amount is a-ok! Since 4Life Transfer Factor is considered a “food,” it’s nearly impossible to take too much.*  
  • When is the best time to take Transfer Factor?
    We recommend taking your daily dose of Transfer Factor when you begin your day! As mentioned, 4Life Transfer Factor is clinically proven to activate the immune system within two hours, so the sooner you take it, the sooner your body will benefit. You can also take a second dose of Transfer Factor in the evening, or whenever you feel you need it, to maintain and optimize your immune system health as you sleep, which is a critical time for your body to repair itself.*1  
  • What if I forget to take my Transfer Factor daily dose in the morning?
    Don’t worry, you can still take your daily dose in the afternoon or evening to maintain and optimize your immune system function.* 
  • How can I get my 600 mg daily dose of 4Life Transfer Factor?  
    Many 4Life products can help you achieve your daily dose. For example, 4Life Transfer Factor Tri-Factor Formula, 4Life Transfer Factor Chewable Tri-Factor Formula, RioVida, RioVida Stix, RioVida Burst, 4Life Transfer Factor Immune Boost, RiteStart Kids & Teens, Pro-TF Vanilla Cream, Pro-TF Chocolate, or a combination of the above products are all great daily options to restore your immune support.*  
  • How did 4Life discover the daily dose?
    4Life’s Research and Development team collaborated with Natural Immune System Labs (NIS) in a human clinical study to discover how fast Transfer Factor can boost the immune system. The study showed that 600 milligrams of 4Life Transfer Factor Tri-Factor Formula activates the immune system in as little as two hours!*1
