Can You Take Both Together?

In most cases, Lactoferrin and L-Theanine can be taken together safely. However, always check the interactions section of each supplement and consult a healthcare professional if you take medication.

Which Should You Choose?

Choose Lactoferrin if your primary goal is: immune system support. Choose L-Theanine if your primary goal is: calm focus without sedation.
