<<Disclaimer: Verify this information before applying it to your situation.>> Hi It is Ted again.I am sorry to even confuse anybody even more following the glutamic acid hydrochloride subject. When i talked about GDL in my first reply i was thinking about gloconic acid. Sorry. OK. Here the revised reply. Glutamic acid hydrochloride is a salt substitute and flavouring agent. It is w white crystalline powder with a solibility in water of one gram in three ml of water. The salt of glutamic acid is usually referred to as MSG or monosodium glutamate,which function as aflavor enhancer as well as a nutrient and diatary supplement. and saltsubstitute. Some people have allergic reaction to glutamic acids or their salts. There you have it As a mineral substitute you could try also natural sources like kelp,dulse,vegetable broth or stock,as well as eating potatoes with the skin on. Ted Wolff
