Best Supplements to Take With LL-37
LL-37 is the only antimicrobial peptide the human body produces from its own genetic code, and it depends on a small group of nutrients to run its production pathway and execute its immune functions. Vitamin D is the most critical input: the gene that encodes LL-37 has a molecular on-switch that only activates when the active form of vitamin D is present, which means low vitamin D blunts endogenous LL-37 output whether you are relying on the body's own production or using it as an exogenous peptide. Magnesium sits just upstream of that switch because the enzymes that convert stored vitamin D into its active form require magnesium to work, and zinc, selenium, and the synergists on this list determine whether the immune cells LL-37 recruits can actually do their jobs. This guide explains what earns a slot on that list and why, and hands the exact amounts to the MyPeptidePal app, because the right dose of each depends on your protocol, your bloodwork, and what else you are running.
