Not a medical advice, but take a look at magnesium supplements. Many people today don't have enough magnesium in their diets, so their balance / ratio of magnesium to sodium is woefully inadequate.
Some forms of magnesium (e.g., taurate, malate, gluconate, glycinate, orotate) are chelated (bound) and may provide amino acids and are much better absorbed by the body than most popular magnesium oxide (which is almost useless as a source of magnesium as it is ill-absorbed in the stomach and is a mild softener / laxative, as is magnesium sulfate aka Epsom salt).
So do some research, but it may be a natural way that works for you to reduce BP.
Ditto what CutePuppy said.
