Capsules include supplements that’s enclosed in an outer shell. In this capsule are beadlets made from the active ingredient. This outer shell is broken down in the digestive tract and the active ingredient is absorbed into the bloodstream and then distributed and metabolized in much the same way as medication from a tablet. Liposomal zinc helps keep your immune system strong. Because it is necessary for immune cell function and cell signaling, a deficiency can lead to a weakened immune response. Zinc supplements stimulate particular immune cells and reduce oxidative stress.
