Cell-quenching absorption
Old-school supplements break down before your body can fully absorb them. Our liposomal formulas deliver nutrients directly to your cells for enhanced bioavailability.
WHAT IS A LIPOSOME?
It comes from Greek words that mean “fat structure.” They are microscopic bubbles designed to protect the nutrients inside.
WILL I FEEL DIFFERENT?
Our formulas are extra gentle on your stomach, even taken without food. For full benefits, stick with it daily for at least 6 weeks.
IS LIPOSOMAL ALWAYS BETTER?
No. We focus on ingredients shown to benefit from liposomal delivery, such as vitamin D, glutathione, and magnesium. We also include other nutrients that enhance the benefits of the formula.
