IMULIFE
About IMULIFE
We are science, but we’re human.
IMULIFE is a health brand focused on everyday immune health. Rooted in cellular immunology, we bring that focus to our products, starting with probiotic formulas built around clearly identified strains and transparent amounts.
Immune health. A human purpose.
We want to make the science of immune health easier to understand and part of everyday life. We explain what is in each formula, why the ingredients are there and who it is designed for.
One focus. Different stages of life.
We bring our focus on immune health to different stages of life. BiCore is designed for adults and teens ages 13+, while BiJoy is made for children ages 2–12. Both are made in Korea and share three Bifidobacterium strains, with different amounts and supporting ingredients for each age group.

Gene Gui
Founder · Cellular Immunologist
IMULIFE was founded by cellular immunologist Gene Gui. He completed postdoctoral training at Dana-Farber Cancer Institute, a research institute affiliated with Harvard Medical School.
His vision is to bring immunology closer to everyday life through thoughtfully developed products and clear, useful information.
Clear information is part of the formula.
We name every probiotic strain, state its amount per sachet and share the full ingredients and directions. We also link to published research and explain what was studied, so you can explore the details for yourself.
