Decaf only for me. My BP runs only slightly toward high, 145-90 some days. I have a small dose Benicar 5mg for BP but only need it once or twice a week maybe. I check it everyday and there is no doubt the cocoa n coffee lowers my BP within 2 hours. Not a lot but I believe it helps keeps me off everyday BP meds. The theobromine is what is believed to help. Plus Coca is full of all kinds of good flavonoids and fiber and no sugar.
Unfortunately, the Special Dark was tested to have higher toxic mineral levels.
Hershey's Special Dark (1 Tablespoon): Cadmium = 3.2 mcg; Lead = 0.36 mcg
Much better:
Good & Gather Unsweetened (Target) (1 Tablespoon): Cadmium = 0.53 mcg; Lead = 0.32 mcg
