ALA is very inexpensive. The Vitamin Shoppe(a chain of stores in the US) sell 120 tablets of 50 mg ALA for just $8.29. I haven't bought any cilantro, however I can't imagine it being less than 7 cents a dose. Some people take just 25 mg of ALA at a time, so that would be under 4 cents a dose(split the 50 mg tablets in half).
