  • Has 4Life TF-Boost been researched?
    Yes, science is in all we do! TF-Boost has been clinically researched and tested in our labs.
  • Why is Vitamin D important for my immune system?
    Vitamin D is important for normal function of the immune system and supports healthy inflammatory response. Vitamin D can be obtained from dietary sources or can be synthesised in the body by exposure to UV-radiation from the sun. Nevertheless, synthesis of vitamin D in the skin by the action of sunlight is insufficient to meet requirements in some European countries, especially during winter months when there is little sunlight exposure.
  • How often can I take 4Life TF-Boost?
    Take one stick per day during 5 consecutive days.
  • Sometimes when I mix 4Life TF-Boost, some of the powder stays floating on the top. Why is that?
    That is the 4Life Transfer Factor we source from chicken egg yolks. It is less water soluble than the other ingredients, so it takes a little extra mixing to dissolve. This is normal, and you can still drink it without any further mixing, or you can mix your TF-Boost a little more to fully dissolve 4Life Transfer Factor.
  • Is 4Life TF-Boost naturally sweetened?
    Yes! 4Life TF-Boost is sweetened with natural sweeteners like stevia, and sugar.
  • Is 4Life Transfer Factor Immune Boost Gluten free?

  • Can I take 4Life TF-Boost continuously?
    Yes! Especially if you are going to be exposed to everyday situations that may challenge the normal functioning of the immune system, we recommend taking it for five consecutive days. However, you can continue drinking it for more than five days in a row if desired. Keep in mind that food supplements should not be used to substitute a varied and balanced diet and a healthy lifestyle. If you are pregnant, nursing, or taking medication, consult your doctor before use.
