With Metafolin® L-5-MTHF *Multifunctional support for healthy oral immune function L-lysine is an essential amino acid that is transported across membranes via a cationic amino acid transporter system. This allows it to compete with l-arginine for absorption and cellular uptake. In vitro evidence suggests that vitamin E synergizes with l-lysine by supporting healthy protein kinase C activity. Lemon balm extract provides complementary support for natural defenses with immune support from its phenolic compounds. Metafolin® L-5-methyltetrahydrofolate (L-5-MTHF) is the naturally occurring, metabolically active form of folate, an essential B vitamin that helps maintain healthy immune cell populations. Vitamin C and citrus bioflavonoids provide broad-range support for healthy immune responses. Lysine-C Plus maintains healthy arginine metabolism and supports oral and overall immune function Metafolin® is a registered Trademark of Merck KGaA, Darmstadt, Germany.
